Recommandations pour la pratique clinique Nice/Saint-Paul-de-Vence 2022–2023 : Prise en charge du cancer du col de l'utérus avancé

French recommendations for clinical practice, Nice/Saint-Paul-de-Vence 2022-2023: Management of advanced cervical cancer The prognosis of cervical cancer remained pejorative until recently, first-line treatment consisting of platinum-based chemotherapy, associated with bevacizumab whenever possible, without any other therapeutic innovation for several years. However in 2022, immunotherapy appeared in the therapeutic landscape. Pembrolizumab can now be prescribed, thanks to the early access status granted by the HAS in September 2022, in patients with PD-L1 positive tumors. In parallel, bevacizumab generic is now reimbursed, allowing its association with chemotherapy on top of pembrolizumab, if indicated. For patient relapsing after platinium salts, and who never received immunotherapy, cemiplimab could be delivered and reimboursed since spring 2023, whatever could be PD-L1 status. Pretherapeutic work-up includes imaging combining MRI and PET/CT or CT of the chest, abdomen and pelvis, as well as evaluation of PD-L1 status on tumor and immune cells to define the CPS score that will determine eligibility to pembrolizumab treatment (CPS > 1). Possibilities of locoregional treatment depend on individual situations and are discussed on a case-by-case basis in multidisciplinary meetings. Early supportive care is always recommended and inclusion in clinical trials must be systematically considered.

Stratégies ganglionnaires dans les cancers de l’endomètre

In 2018, around 382,100 new cases of endometrial cancer (EC) were reported worldwide, accounting for about 4.4% of all new cases of cancer in women. In France, in 2018, the EC is the first gynecological cancer in incidence and the fourth cancer in women. The rationale for the therapeutic management of EC is based on the estimation of a theoretical risk of recurrence and lymph node metastasis using MRI and preoperative biopsy criteria. However, lymph node status remains the determining factor of adjuvant treatment. In order to reduce the morbidity of lymphadenectomy, the concept of sentinel lymph node biopsy (SLN) has been developed. The SLN technique has evolved in recent years, thanks to the advent of robotics and the creation of fluorescence detection cameras. It has been shown that detection of SLN with Indocyanine Green (ICG) allows for more frequent bilateral migration of 88 to 100% and better detection of pelvic GS in 97% of cases with a decrease in morbidity. Recently, in view of the absence of a therapeutic role of lymph node staging, the operational risks and the delay of adjuvant treatments, in case of pelvic lymph node metastasis on definitive histological examination, the question of secondarily performing paraaortic lymphadenectomy arises. The SLN procedure, extended to all early-stage endometrial cancers, should lead to a major reduction in the use of secondary staging and better adaptation of adjuvant therapy.

Déficit de la recombinaison homologue dans les cancers épithéliaux de l’ovaire : de la caractérisation moléculaire au parcours des patientes

High-grade serous ovarian carcinoma (HGSOC), the most frequent and aggressive form of epithelial ovarian cancer is characterized in half of cases by homologous recombination deficiency (HRD). This molecular alteration is defined by distinct causes and consequences. The main and most characterized cause is the presence of an alteration affecting BRCA1 and BRCA2 genes. Regarding consequences, a specific genomic instability leads to increased sensitivity to platinum salts and poly (ADP-ribose) polymerase (PARPi) inhibitors. This latter point enabled the advent of PARPi in first and second line maintenance. As such, the initial and rapid evaluation of HRD status with molecular tests is a key step in the management of HGSOC. Until recently, the range of tests offered proved to be very limited and suffered from technical and medical limitations. This has recently led to the development and validation of alternatives, including academic ones. This "state of the art" review will bring a synthesis concerning the assessment of HRD status in HGSOCs. After a brief introduction of HRD (including main causes and consequences) and of its predictive value regarding PARPi, we will discuss the limitations of current molecular tests and the existing alternatives. Finally, we will contextualize this to the situation in France, with special consideration concerning the positioning and the financial coverage of these tests, with the perspective of optimizing patient management .

Real-world dostarlimab use in advanced/recurrent endometrial cancer in France

In October 2020, the French Health Authority granted early access outside of the clinical trial setting for dostarlimab, a programmed death-1 inhibitor. Dostarlimab was approved by the European Medicines Agency (in April 2021) as monotherapy for patients with post-platinum mismatch repair deficient/microsatellite instability-high advanced/recurrent endometrial cancer, based on the results of the GARNET trial (NCT02715284). This was a real-world descriptive analysis of patients granted cohort temporary authorization of use to receive dostarlimab between November 2020 and June 2021. Physicians could complete follow-up forms at each treatment cycle to provide clinical information, safety, and efficacy data. Safety and disease progression data were also captured through pharmacovigilance reports. Of 95 temporary authorization of use requests made by 80 oncologists in 59 French hospitals, 87 patients were eligible, and 80 received≥1 dose of dostarlimab. Based on treatment response assessments received (n=43), the mean (standard deviation) time from treatment initiation to response evaluation was 11 (6) weeks. The disease control rate (complete plus partial responses plus stable disease rates) was 56% (n=24/43), and the overall response rate was 35% (n=15/43); both consistent with those reported in the GARNET trial. No new safety signals were reported. The enrolment of 80 patients in an 8-month period highlights the need for access to novel treatment regimens in France for these patients post-platinum. Prospective randomized studies are ongoing to assess the efficacy and safety of dostarlimab and other checkpoint inhibitors as first-line treatment in patients with endometrial cancer.

Étude rétrospective : chirurgie d’intervalle tardive post chimiothérapie versus après 3–4 cures dans le cadre de la prise en charge d’un cancer de l’ovaire localement avancé non opérable d’emblée

Treatment in locally advanced ovarian cancer is optimal surgery followed by chemotherapy. Patients with significant tumor spread, OMS>2, age>75 years old are poor candidates for aggressive primary surgery. Interval surgery, after neo-adjuvant chemotherapy, aims to achieve more complete surgery, increase survival, and reduce surgical morbidity. The primary endpoint was progression-free survival. Secondary outcomes were overall survival and postoperative morbidity and mortality. This is a retrospective study conducted in 2 French referral centers between January 2000 and December 2015. Patients who could not benefit from a complete initial surgery were operated after 3 cures of chemotherapy at the François Baclesse center and after least 5 cures at the center René Gauducheau. The population analyzed included 104 patients, 43 (41.0%) patients treated at the René Gauducheau center (group 1) and 61 (59.0%) patients treated at the François Baclesse center (group 2). Progression-free and overall survival were similar between the 2 groups, they were, respectively, 15.9 months and 34 months in group 1 vs. 15.4 months and 37.6 months in group 2 (P=0.72; P=0.65). Mean hospital stay and postoperative morbidity were similar in both groups. For weak patients, to limit invasive surgery, doing more than 5 courses of chemotherapy may be a reasonable option.

Reste-t-il des indications de curage ganglionnaire dans les cancers épithéliaux de l’ovaire après l’essai LION ?

In March 2019, Harter et al. published the results of the LION study (Lymphadenectomy in patients with advanced ovarian neoplasms) which raises the question of pelvic and para-aortic lymphadenectomy for patients with advanced-stage epithelial ovarian cancer (EOC). These results influenced the new French recommendations published in December 2018 by the French National Cancer Institute (INCa). Thus, it no longer seems consistent to perform a systematic lymphadenectomy for patients for whom there is no argument for nodal involvement, when a macroscopic complete peritoneal cytoreductive surgery has been performed. The question of preoperative lymph node assessment is therefore essential, whereas more than half of the patients in the LION study had metastatic lymph node involvement that was histologically proven. For the assessment of lymph node status by imaging, superior sensitivity for Positron Emission Tomography is demonstrated in comparison with CT-scan or Magnetic Resonance Imaging. Nevertheless, thoraco-abdomino-pelvic CT-scan with contrast injection remains the gold standard for this indication. In the absence of suspected involvement, supra-renal, mesenteric, coelio-hepatic, and cardio-phrenic lymphadenectomy are not recommended. Lymphadenectomies should always be performed in the other situations of EOC management apart from the rare case of stage 1 expansile subtype mucinous carcinoma. The aim of this review is to discuss lymphadenectomy indications for the surgical management of EOC by taking into account new data from the scientific literature.

Mise à jour 2021 des recommandations pour la pratique clinique de Nice/Saint-Paul-de-Vence dans le cancer de l’ovaire épithélial de haut grade

Since the previous 2013 and 2016 recommendations for clinical practice (RPC) Nice/Saint-Paul-de-Vence for gynecological cancers, the management of ovarian cancer has become more complex with the evolution of the quality criteria recommended for surgery and the integration of molecular biology for the decision of medical treatments, especially for high grade epithelial ovarian cancers. Surgical indications have become more precise both in the first line and in the context of relapse. Treatments with PARP inhibitors is a major advance in medical management with significant efficacy in maintenance after response to platinum-based chemotherapy. The benefit already known in the case of late relapse has also been demonstrated in first-line treatment with progression-free survival never observed in this pathology with patients with very long responses, especially in the case of BRCA gene abnormalities (somatic or constitutional). In 2021, medical and surgical strategies in front line including PARP inhibitors associated or not with bevacizumab as a maintenance complement after platinum chemotherapy are guided by both response to platinum agents and molecular profiling including BRCA (somatic or constitutional) genetic status and homologous recombination pathway (HRD) abnormalities, that should be early tested. On behalf of the GINECO national oncologist group, we have updated the guidelines for high grade ovarian epithelial cancer (excepted rare tumors) in order to allow rapid dissemination of the latest advances to the medical community and improve daily practice.

Diagnostic histologique et moléculaire des cancers de l’ovaire – recommandations pour la pratique clinique Saint-Paul 2021

Oncogenetic testing is now part of standard management in high grade ovarian cancer, including at least mutational status of BRCA1/BRCA2 genes. If necessary, tumor genetic testing is followed by constitutional testing to either confirm the constitutional origin of variants identified in BRCA1/2 genes or detect variants in other predisposition genes. The whole process including prescription of tumoral testing, retrieval of analysis report and communication of results must be formalized, as well as information on possible consequences of the results for the patient and her family. Tumor material must meet criteria of size and cellularity to allow high-quality analysis. These samples are processed during the preanalytical phase with two major steps : time of cold ischemia and fixation. Only pathogenic (Class V) and likely pathogenic (Class IV) variants shown in tumor tissue are mentioned in the report. Currently, only BRCA1 and BRCA2 genes are routinely studied but, in the future, analysis will be extended to other genes involved in homologous recombination repair. In patients without BRCA mutation, other biomarkers reflecting sensitivity to PARP inhibitors, such as HRD scores (homologous recombination deficiency) that appeared recently, will have to be implemented in routine practice in order to better select patients for these treatments and choose optimal therapy.

Prise en charge chirurgicale du cancer épithélial de l’ovaire – première ligne et première rechute

Based on recently published data, these recommendations present some evolutions in the surgical management of high grade epithelial ovarian cancers. In apparently early stages (FIGO I and II), surgical staging must be undertaken to confirm the absence of both peritoneal lesions and lymph node involvement (that might change stage and management). Neoadjuvant chemotherapy is not indicated, surgical exploration should be performed upfront, by laparotomy, to reduce the risk of rupture of the primary tumor. In advanced stages, the first step is to evaluate the feasibility of primary surgery with complete tumor cytoreduction. If it appears unfeasible, 3 or 4 cycles of neoadjuvant chemotherapy are administered before interval surgey. Whether it is implemented in the primary or interval setting, surgery must be performed by experimented teams, in an approved facility, having developed a rehabilitation program. Lymph node dissection is not mandatory if no adenopathies have been identified by imaging and by peroperative palpation. At first relapse, the surgical decision must be made by a multidisciplinary team, using scores predictive of complete cytoreduction (AGO or iMODEL criteria). Similarly as in first line, the objective is to achieve resection without any residual disease. Surveillance after first-line treatment must be adapted, according to the probability of another complete cytoreduction in case of late relapse, especially in patients who benefited from primary complete surgery and maintained good performance status.

Certification nationale pour la chirurgie des cancers gynécologiques

In France, we are lacking an identified pathway for training in gynaecological cancer surgery. The four competent French learned societies: the SFOG, the CNGOF, the SFCO and the SCGP supported by the CNU of Obstetrics & Gynaecology, and UNICANCER agreed to materialize this course and attest it by a certification awarded by a national jury. The national committee of certification in gynaecological oncology made up of ten members, representing the 6 concerned organizations, set itself five objectives: the definition of the eligibility criteria for training centres; the determination of a check-list to be filled by the candidate; the determination of a targeted curriculum for the training in gynecological oncological surgery; the determination of the assets necessary for the certification of a candidate already in practice; and the practical organization of the certification. Criteria for approval of centres for training included 150 gynaecological cancer cases per year, among which 100 excisional surgeries, including twenty advanced-stage ovarian cancers. For certification of candidate who followed the curriculum established by the committee or by validation of prior experience for an actual practitioner, a candidate must validate a logbook and fill out a checklist including four parts: theoretical and practical training; research and publications; teaching and subscription to a continuing education program. The accomplished elements of the logbook and the checklist will be evaluated by a score. The first certification session is planned for the end of 2021.

De la biologie des tumeurs de la granulosa de l’ovaire à la perspective de nouvelles thérapeutiques au-delà de la chimiothérapie

Granulosa cell tumors (GCTs) are rare ovarian neoplasms, accounting for 2-5% of all ovarian cancers. Two histological types have been described: juvenile (JGCT) and adult (AGCT), the latter accounting for around 95% of the GCTs. AGCTs are mostly diagnosed at an early stage and commonly have a good prognosis. However, GCTs tend to be associated with late recurrence in about a third of cases which are a major concern. These recurrences often require repeated surgical interventions. Systemic treatments, for their part, show limited effectiveness in this context, highlighting the need to identify new therapeutic targets. Thus, better biological characterization of these tumors would enable us to propose more targeted treatments. To achieve this, the molecular characteristics of GCTs have been explored. Most AGCTs harbor a mutation in the FOXL2 transcription factor sequence, therefore allowing to investigate therapeutic perspectives targeting its signalling, as well as setting the first steps towards immunotherapy in these tumors. Knowledge of JGCTs is more limited due to their rarity. However, molecular analysis revealed that ∼60% of the JGCTs bore a genetic mutation in the AKT1 oncogene. However, its clinical significance has still to be explored. For both GCTs subtypes, the CDK4/6-Rb1 axis is promising. Consequently, exploring the molecular features and their role in the biology of these tumors could open up new avenues for targeted and personalized therapies, thereby improving patient care.

Prospects of the therapeutic approaches of ketogenic diet on the clinical outcomes of cancer: A scoping review

The scientific community has become more enthusiastic about ketogenic diet (KD) to improve the outcomes in medical conditions, including cancer by exploiting the reprogramed metabolism of cancer cells, making the diet a promising candidate as an adjuvant cancer therapy. From this perspective, the aim of this study was to provide a broad overview covering the therapeutic effects, evaluating the clinical evidence of clinical studies underlying the implementation of the KD in the context of cancer treatment and prognosis. A scoping literature search between the years 1990 and 2023 was carried out by using PRISMA guidelines and searching through different databases of the clinical studies supporting the effectiveness and benefits of KD in various carcinomas that could provide findings of evidence on the prognosis and clinical outcomes of cancer treatment. A total of 23 cancer-related publications were included, 12 of which focused on brain cancer particularly glioblastoma multiforme (GBM), 4 on both breast and ovarian cancers, and 3 on pancreatic cancer. A total of 10 publications were reported as clinical trials regarding cancers of the brain (4 studies), breast (2 studies), and ovarian (4 studies). Case report studies were reported in 3 publications for brain cancer, and 2 publications for breast cancer. Nearly almost of the studies found that there was a potential role of KD in the prognosis of cancer treatment. The current review suggests that cancer patients may get favorable effects from the implementation of KD to support clinical outcomes of cancer treatment.

Ovarian mature teratomas: Differences in management and outcomes in adolescents cared for by gynecologic and pediatric surgeons

Ovarian mature teratomas (OMTs) are the most common benign ovarian tumors in pediatric patients. Management in adolescents can be performed by pediatric (PSs) or gynecologic surgeons (GSs). The aim of this study was to assess the differences in OMT management and the repercussions according to the risk of secondary events. Based on a multicentric study, we compared patients aged 14 to 18 who underwent surgery for OMT between 2009 and 2022 from the French national pediatric database of OMTs with patients managed by GSs. In total, 119 patients were included (80 by PSs, 39 by GSs). Differences between teams were noted: (i) tumor marker analysis is systematic by PSs (80%, n=72) but rare by GSs (18%, n=7) (P<0.001), (ii) PSs mostly carried out a laparotomy (78%, n=62), whereas GSs preferred laparoscopy (90%, n=35) (P<0.001), (iii) peroperative rupture was more frequent by GSs (56%, n=22) than PSs (10%, n=8) (P<0.001), (iv) median duration of follow-up increased by PSs (20months) versus 1month by GSs (P=0.001). Ten second events (13% by GSs [n=5], 6% by PSs [n=5]) occurred in nine patients, without significant differences (P=0.151). A notable difference exists in the management of OMTs between PSs and GSs in our study, GSs may overlook a malignant component in germ cell tumors in adolescents and the risk of metachronous recurrence, reported up to 10-20%. We recommend a compliance to SIOPE 2020 guidelines (Sessa et al., 2020) to avoid rupture of potential malignant tumor and to preserve fertility.

The association between oral contraceptive pills and ovarian cancer risk: A systematic review and meta-analysis

Previous study results have been inconclusive, so this meta-analysis aims to evaluate the association between ovarian cancer and oral contraceptive pills (OCPs). PubMed, EMBASE, Scopus, and Web of Science were searched to identify studies on the association between OCPs and ovarian cancer from January 1, 2000 through February 5, 2023. The pooled relative risk (RR) and odds ratio (OR) were used to measure this relationship. A total of 67 studies were included. In the association between ever-use compared with never-use of OCPs and ovarian cancer risk, the pooled RR in cohort studies was 0.69 [95% CI: 0.61, 0.78]. For the relationship between duration of OCPs use and ovarian cancer in the cohort studies, no association between duration of use1-12 months 0.92 [95% CI: 0.82, 1.03] and duration of use 13-60 months 0.87 [95% CI: 0.73, 1.04], but there is a statistically significant inverse relationship between duration of use 61-120 months 0.62 [95% CI: 0.48, 0.81] and more than 120 months 0.51 [95% CI: 0.32, 0.80] and ovarian cancer. For the relationship between OCPs and histological subtype of epithelial ovarian cancer in the cohort studies, the pooled RR for invasive was 0.70 [95% CI: 0.56, 0.87], but no association between OCPs and borderline ovarian cancer 0.64 [95% CI: 0.31, 1.31]. Our analysis shows a statistically significant inverse relationship between ever-use compared to never-use of OCPs and ovarian cancer risk,and also between invasive cancer and OCPs. By increasing the duration of OCPs use, the risk of ovarian cancer decreased.

Prise en charge médicale de la récidive du cancer épithélial de l'ovaire

The panel of therapeutic options available for medical treatment of relapsed ovarian cancer increased over the last years. In late, platinum-sensitive relapse, standard treatment remains platinum-based polychemotherapy. The choice between bevacizumab added to chemotherapy followed by maintenance and inhibitors of poly-(ADP-riboses) polymerases (PARPi) after response to platinum-based therapy should be discussed, taking into account prior treatment, contraindications, and disease characteristics (biology, symptoms…). The addition of bevacizumab at first platinum-sensitive relapse can be considered if it has not been administered in first line, and it is optional (rechallenge) if previously administered (but without Marketing Authorization in this setting). PARPi are indicated for maintenance therapy after response to platinum-based chemotherapy (whatever the treatment line), regardless of BRCA mutational status, in case of no prior administration. Early relapses are associated with poor prognosis and therapeutic options are more limited. They are treated by monochemotherapy without platinum agents, associated with bevacizumab if not administered previously. Beyond first early relapse, there is no standard and inclusion in a clinical trial should be proposed if possible. Several clinical studies assessing associations of immunotherapy and chemotherapy and/or antiangiogenic drugs and/or targeted therapies (such as PARPi) are ongoing in early or late relapse.

CAR-T cells, from principle to clinical applications

Chimeric antigen receptors (CAR)-T cells are genetically engineered T-lymphocytes redirected with a predefined specificity to any target antigen, in a non-HLA restricted manner, therefore combining antibody-type specificity with effector T-cell function. This strategy was developed some thirty years ago, after extensive work established the key role of the immune system against cancer. The first-engineered T-cell with chimeric molecule was designed in 1993 by Israeli immunologist Zelig Eshhar. Since then, several modifications took place, including the addition of co-stimulatory domain, to further improve CAR-T cell anti-tumor potency. The first clinical application of CAR-T cell was done in Rotterdam in 2005 for metastatic renal cell carcinoma and simultaneously at the National Cancer Institute (NCI) for metastatic ovarian cancer. These pioneered studies failed to demonstrate a therapeutic benefit, but warning emerged concerning their safety of use. The real clinical success came with anti-CD19 CAR-T cells, used since 2009 by Steven Rosenberg at the NCI in a patient with refractory follicular lymphoma and in 2011 by Carl June and David Porter from the University of Pennsylvania in patients with chronic lymphocytic leukemia and B-cell acute lymphoblastic leukemia. From that time, large centers in North America have embarked in several early phase and pivotal trials that have demonstrated unprecedent response rate in heavily pretreated chemo refractory patient with B-cell malignancies. Theses clinical success have led to the approval of three anti-CD19 CAR-T cells products for the management of B-cell malignancies in the United States and in Europe as of December 2020.

Combinaison de la chirurgie et du traitement médical du cancer de l’ovaire : y a-t-il une stratégie optimale ?

The objective of this review is to evaluate the optimal positioning of cytoreduction surgery and perioperative medical treatments in the initial management and relapse of advanced-stage epithelial ovarian carcinoma. In the initial management, primary surgery should be proposed if the absence of tumor residue is feasible with reasonable surgery (extensive surgical resections to be considered and their complications, but also the general condition of the patient). Guidelines recommend 3 to 4 cycles of neoadjuvant chemotherapy before interval surgery for patients not eligible for primary surgery. Late interval surgery (i.e. after≥5-6 cycles of chemotherapy) is not a standard of care and should only be proposed in case of poor tumor response after 3-4 cycles and when complete interval surgery seems feasible. At first tumor recurrence in platinum-sensitive patients, a primary cytoreduction surgery can be considered if complete surgery can be managed. Predictive scores (AGO score; i-model score) can be used to select eligible patients. Given the lack of strong evidence, performing cytoreduction surgery at first recurrence in platinum-resistant patients or in the event of subsequent recurrence cannot be recommended. Nevertheless, obtaining a complete surgery in these clinical situations seems to provide a benefit in terms of overall survival and its application should be based on the expertise of specialized teams.

Diagnostic des sarcomes utérins et tumeurs mésenchymateuses utérines rares à potentiel de malignité. Référentiels du Groupe Sarcome Français et des Tumeurs Rares Gynécologiques

The landscape of uterine sarcomas is becoming more complex with the description of new entities associated with recurrent driver molecular alterations. Uterine sarcomas, in analogy with soft tissue sarcomas, are distinguished into complex genomic and simple genomic sarcomas. Leiomyosarcomas and undifferentiated uterine sarcomas belong to complex genomic sarcomas group. Low-grade and high-grade endometrial stromal sarcomas, other rare tumors associated with fusion transcripts (such as NTRK, PDGFB, ALK, RET ROS1) and SMARCA4-deficient uterine sarcoma are considered simple genomic sarcomas. The most common uterine sarcoma are first leiomyosarcoma and secondly endometrial stromal sarcomas. Three different histological subtypes of leiomyosarcoma (fusiform, myxoid, epithelioid) are identified, myxoid and epithelioid leiomyosarcoma being more aggressive than fusiform leiomyosarcoma. The distinction between low-grade and high-grade endometrial stromal sarcoma is primarily morphological and immunohistochemical and the detection of fusion transcripts can help the diagnosis. Uterine PEComa is a rare tumor, which is distinguished into borderline and malignant, according to a risk assessment algorithm. Embryonal rhabdomyosarcoma of the uterine cervix is more common in children but can also occur in adult women. Embryonal rhabdomyosarcoma of the uterine cervix is almost always DICER1 mutated, unlike that of the vagina which is wild-type DICER1, and adenosarcoma which can be DICER1 mutated but with less frequency. Among the emerging entities, sarcomas associated with fusion transcripts involving the NTRK, ALK, PDGFB genes benefit from targeted therapy. The integration of molecular data with histology and clinical data allows better identification of uterine sarcomas in order to better treat them.

Prise en charge du cancer de l’endomètre métastatique et/ou en rechute. Recommandations 2020 pour la pratique clinique (Colloque de Nice-Saint Paul de Vence)

Endometrial cancer is a common cancer in older women and is often associated with comorbidities. Management of metastatic disease and/or relapse requires a multidisciplinary approach. Recent advances in the understanding of oncogenesis and molecular classification of endometrial cancers offer new therapeutic perspectives. These first recommendations, established following the methodology of Nice-Saint-Paul recommendations for clinical practice (RPC), aims to integrate molecular advances in diagnostic and therapeutic management. In 2020, the histological diagnosis of endometrial cancer is based on morphology and immunohistochemistry, including at least p53, oestrogen and progesterone receptors. Deficiency in the DNA mismatch repair system (MMR) must be assessed in all advanced endometrial tumors for oncogenetic and theranostic purposes. It can be sought initially by an analysis in immunohistochemistry with the 4 markers (MLH1, MSH2, MSH6, PMS2). Medical treatment depends on histological type, presence of hormone receptors and patient's profile to refer to chemotherapy (carboplatin-paclitaxel) or hormone therapy (for example of the progestogen type); in the event of MMR-deficiency, immunotherapy trial is the best option. As part of overall management of advanced endometrial cancer, radiotherapy (and surgery in rare cases) must be discussed, in particular in the event of loco-regional only relapse or oligometastatic disease.

La formation spécialisée transversale en cancérologie pour les internes en gynécologie médicale : retour sur cinq ans d’existence

The transversal specialized formation (TSF) in oncology has been enabling non-oncologist physicians to acquire oncology skills for five years. This study aims to assess the TSF for medical gynecology residents. A 23-item questionnaire was sent to physicians from the specialized medical degree (SMD) in medical gynecology who completed the TSF between 2020 and 2023. The data were analyzed using Student's t-tests, Fischer tests, and Chi Of the 22 residents identified, 20 (90.9%) responded to the questionnaire. Nine residents (40.9%) were from the Paris region. The reasons for undertaking the TSF included interest in gynecological and breast cancers (81.8%), clinical richness (50.0%), and scientific dynamism (50.0%). Of the 11 respondents who had completed the SMD or had a defined post-residency project, all reported working in a hospital setting. The main activity was gyneco-oncology (n=6, 55.0%), including sexology, monitoring at-risk women, post-cancer care, and medical oncology (n=5, 45.0%). The average satisfaction with the TSF was 7.2/10, with no significant regional difference (P=0.62). Suggested areas for improvement included harmonizing theoretical courses, offering specialized internships in gynecological oncology, and providing mentorship. Five years after its implementation, medical gynecologists are satisfied with the TSF in oncology. The main requests are for strengthening national courses and expanding the range of internships, all focused on the original specialty.

Correlation between HPV-16 integration status and cervical intraepithelial neoplasia and cervical cancer in patients infected with HIV

This study aimed to explore the mechanism by which HIV infection promotes cervical cancer and precancerous lesions. This was a retrospective observational study including 96 patients with high-risk HPV-16 infection who underwent cervical biopsy, cervical conization, or hysterectomy. Among them, 43 patients were diagnosed with both HIV and cervical cancer or precancerous lesions. High-risk HPV infection (HPV16+) positive samples were collected, and total RNA was extracted and amplified by fluorescence quantitative PCR. The expression of HPV E2 and E6 in cervical tissues of HIV-infected and non-HIV-infected patients with high-risk HPV was determined. As the degree of cervical tissue lesions increased, the proportions of integrated HPV-16 increased significantly within both HIV-negative (P=0.008) and HIV-positive groups (P=0.027). In comparison to the HIV-positive group, although the HIV-negative group had a higher proportion of free type HPV-16 infection (64.3% vs. 35.7%) and a lower proportion of integrated type infection (41.7% vs. 58.3%), the differences were not statistically significant (P=0.117). The lower the CD4+ T lymphocyte level, the greater the possibility of HPV-16 integrated infection. Patients with HIV and HPV-16 infection exhibit a significantly higher rate of integrated HPV-16 infection, which is closely linked to HIV-induced immunosuppression, particularly the depletion of CD4+ T lymphocytes. This integration accelerates the progression of cervical lesions, increasing the risk of developing high-grade cervical intraepithelial neoplasia or cervical cancer. These findings underscore the need for targeted screening and therapeutic strategies in HIV-positive women to prevent HPV-related malignancies.

Therapeutic effect of haploidentical peripheral blood stem cell treatment on relapsed/refractory ovarian cancer

The traditional immunotherapy is limited on relapsed/refractory metastatic ovarian cancer because tumors cause immunosuppression. Since new therapeutic strategies to improve clinical outcomes for patients with relapsed/refractory metastatic ovarian carcinoma are needed, the aim of this study was to evaluate the therapeutic effect of haploidentical peripheral blood stem cells (haplo-PBSCs) adoptive treatment on relapsed/refractory ovarian cancer. Thirteen patients with advanced stage of ovarian cancer and refractory history after surgery and chemotherapy were treated with interleukin-2 activated haplo-PBSCs donated by their parents or children. Clinical outcomes including therapeutic response by measuring tumor size changes using CT scanning, CA-125 levels and survival times were evaluated. T and NK cell population in patients before and after treatment was detected by flow cytometry analysis. The median follow-up time after haplo-PBSCs adoptive treatment was 14 months. At the time of the last follow-up, the median overall survival after haplo-PBSCs adoptive treatment was 9.1 months. Ten patients (76.9%) achieved a relief of symptoms, including abdominal distention, ache, fatigue, and poor appetite. During the first 2 months after treatment, CA125 levels decreased in 10 patients (76.9%). Five patients (38.5%) had a stable disease and 1 patient (8%) had partial response. T cell population (CD3

Impact of complete surgical staging on survival of patients with early-stage (FIGO I or II) ovarian cancer: Data from the Cote d’Or Registry of Gynecological Cancers from 1998 to 2015

Early-stage ovarian cancer represents 20 to 33% of all ovarian cancers and is thus quite rare in France, with around 1200 new cases per year. No study to date has convincingly demonstrated the utility of lymphadenectomy in early-stage ovarian cancer. We sought to evaluate the impact on overall survival of complete surgical staging in patients management for FIGO stage I and II ovarian cancer. We performed a retrospective observational study using data from the Cote d'Or Registry of Gynecological Cancers. We included patients with invasive early stage epithelial ovarian cancer (FIGO stages I and II), diagnosed between 1 January 1998 and 31 December 2015. A total of 179 patients were included in the study. Patients who had lymphadenectomy were younger on average (P<0.001) and had fewer comorbidities (P=0.03). Lymphadenectomy was performed during the first surgery in 59.2% of cases (58 patients) and during a second, re-staging surgery in 40.8% (n=40). When complete surgical staging was performed, the rate of up-staging (to at least FIGO stage III) was 11.2% (11/98). The median follow-up was 8.4 years. At the study, 31.6% patients with complete surgical staging had died and 48.4% patients also died in the group without lymphadenectomy, HR 0.59 CI [0.36-0.97] P<0.04. In patients with early-stage ovarian cancer, complete surgical staging appears to yield a benefit in terms of overall survival. In 10 to 15% of cases, it leads to upstaging, with the resultant indication for maintenance therapy, which has also shown a survival benefit.

Recommandations pour la pratique clinique Nice/Saint-Paul-de-Vence 2024–2025 : prise en charge cardio-oncologique des principaux schémas thérapeutiques en onco-gynécologie

New therapeutic options for gynecological cancers (in particular, targeted therapies and immunotherapies) are associated with potential cardiovascular toxicities that oncologists should be able to identify, detect and manage together with a cardiologist. The first step consists of evaluating the patient's individual cardiovascular risk, regardless of planned oncologic treatment, to determine whether this treatment can be initiated immediately or if cardiological advice is required. In a second step, the risk of cardiovascular toxicity of the selected treatment must be assessed, considering its intrinsic risk and the patient's comorbidities. Once treatment has started, appropriate monitoring should be implemented during administration, and after discontinuation. Beyond general recommendations, specific situations are detailed for initial workup and surveillance relating to most common protocols of chemotherapy, immunotherapy, targeted therapy and associations used in gynecological oncology. If cardiotoxicity occurs (hypertension, QT interval increase, left ventricular dysfunction, troponin increase, myocarditis), the oncologist must be aware of the principles of management, and distinguish between what he can manage on his own and what requires referring to specialists. Prior to rechallenge after cardiotoxicity, multidisciplinary discussion is mandatory to assess the patient's benefit/risk ratio.

Results of a National French Survey on use of KELIM model for management of patients with advanced stage epithelial ovarian cancer (SFOG Campus)

Ovarian cancer, predominantly epithelial, is the ninth most common and fifth most lethal cancer among women in France, with late diagnosis and poor prognosis despite curative treatments. The KELIM model, built according to Ca125 kinetics, given its proven predictive and prognostic characteristics, has been implemented online to aid therapeutic decision-making. This study assessed the use of the KELIM score among French gynecological oncology experts using a survey sent from 13 December 2023 to 30 January 2024, through Google forms to all member of French Society of Gynecological Oncology (SFOG), Young of French Society of Gynecological Oncology (SFOG campus) and National Investigators Group for Ovarian and Breast Cancer Studies in France (GINECO-ARCAGY). Fifty-two respondents, mainly gynecology and medical oncologists, revealed that 58% of them have used KELIM score, primarily in neoadjuvant settings. Participants considered that the KELIM score was mainly used to define the chemosensitivity (79%) and to identify patients who could then receive bevacizumab (82%). In the maintenance setting, the KELIM score was reported as quite frequently used (41%). It was inconsistently used to help the surgical procedure decision (37%). The KELIM score predictive value for chemosensitivity, is acknowledged, especially for bevacizumab indications. However, its adoption into routine practice is dependent on the level of familiarity of practitioners. The findings suggest that while KELIM is seen as a potential useful tool for reinforcing therapeutic strategies, including choice of maintenance therapy or sequence of cytoreduction surgery, its broader adoption requires enhanced education and prospective validation.

Statement of the AGO Kommission Ovar, AGO Study Group, NOGGO, AGO Austria, Swiss AGO, BGOG, CEEGOG, GEICO, and SFOG regarding the use of hyperthermic intraperitoneal chemotherapy (HIPEC) in epithelial ovarian cancer

An international joint statement about the use of hyperthermic intraperitoneal chemotherapy (HIPEC) in ovarian cancer was published in 2016, warning about the uncritical use of HIPEC outside controlled studies. This statement has now been updated after the most recent literature was reviewed by the participating study groups and societies. HIPEC became a treatment option in patients with advanced colon cancer after positive results of a randomized trial comparing surgery and HIPEC versus palliative treatment alone. Although this trial did not compare the added value of HIPEC to surgery alone, HIPEC for the treatment of peritoneal metastases was in the subsequent years generalized to many other cancer types associated with peritoneal carcinomatosis including epithelial ovarian cancer (EOC). In the meantime, new evidence from prospective randomized trials specifically for EOC-patients emerged, with however contradicting results and several quality aspects that made the interpretation of their findings critical. Moreover, three additional trials in colorectal cancer failed to confirm the previously presumed survival benefit through the implementation of HIPEC in peritoneally disseminated colorectal cancers. Based on a still unclear and inconsistent landscape, the authors conclude that HIPEC should remain within the remit of clinical trials for EOC-patients. Available evidence is not yet sufficient to justify its broad endorsement into the routine clinical practice.

HJURP inhibits proliferation of ovarian cancer cells by regulating CENP-A/CENP-N

High expression of Holliday Junction-Recognizing Protein (HJURP) has been shown to be a marker of poor prognosis in ovarian cancer. The objective of this study was to investigate the molecular mechanisms of HJURP in ovarian cancer (OC) progression. Gene Expression Profiling Interactive Analysis (GEPIA) was used to analyze the gene expression profile. Real-time quantitative PCR (qRT-PCR) was used to detect the expression level and correlation of HJURP and centromere protein-A (CENP-A) in OC tissues and cell lines. CCK-8 assay was used to detect cell proliferation. The expression level of apoptosis-related proteins and cell cycle-related proteins were detected by western blotting. Cell cycle and mitochondrial content were determined by flow cytometry. The results showed that HJURP was up-regulated in OC tissues and cell lines, while the cell proliferation was inhibited after transfecting by si-HJURP. Knockdown of HJURP promoted cell apoptosis. Meanwhile, low-expression of HJURP could down-regulate cell replication cycle-related proteins (Cyclin-dependent kinase 2, cyclinD1 and Cyclin-dependent kinase 4) and make cell replication stay in the S phase. Moreover, further studies showed that HJURP was positively correlated with CENP-A in OC tissues. Finally, the rescue experiment further verified that HJURP targeted regulation of CENP-A in OC. The study indicated that HJURP plays a significant role in OC and could target CENP-A to regulate OC cell growth. These findings provide a clue to the diagnosis and treatment of OC.

Place du ganglion sentinelle dans les cancers du col utérin débutants

Lymph node status is the most important prognostic factor of survival in women with early stage cervical cancer. Sentinel lymph node (SLN) biopsy is an accurate method for the assessment of lymph nodal involvement in early-stages cervical cancer and has been increasingly used instead of systematic pelvic lymph node dissection (PLND). Less-radical lymph node dissection decreases the associated morbidity of PLND, especially the risk of lower-leg lymphoedema, which affects severely patient quality of life. SLN biopsy allows nodes ultrastaging and provides supplementary histological information by increasing the detection of tumor low-volume (isolated tumors cells and micrometastases). Moreover, SLN biopsy provides accurate anatomical information on pelvic lymphatic drainage pathway by identifying nodes outside of routine lymphadenectomy areas. Selection of a population at low-risk of nodal metastasis, a minimal training, and simple rules may ensure a low false negative rate. Several studies have shown that SLN mapping in these patients is feasible, with excellent detection rates and sensitivity. Combined detection with technetium-99 and blue dye has been widely used but recently, there has been increasing interest in the use of fluorescent dies such as indocyanine green (ICG) which would improve SLN detection. Although recent international guidelines recommend performing SLN biopsy in addition to PLND, SLN biopsy alone is not the gold-standard yet due to lack of prospective evidence, especially on long-term oncological safety. Some points remain controversial such as the low accuracy of intraoperative SLN status assessment by frozen section and the impact of micrometastasis on prognostic. The prospective randomized clinical trial SENTICOL III will answer to these problematics.

Recommandations pour la pratique clinique Nice/Saint-Paul-de-Vence 2022–2023 : Prise en charge du cancer de l'endomètre métastatique et/ou en rechute

Recommendations for clinical practice Nice/Saint-Paul-de-Vence 2022-2023 : Management of advanced/relapsing endometrial cancer Since the first recommendations in 2020 concerning metastatic and/or relapsed endometrial cancer, new treatment options have shown a benefit on patients' life expectancy, justifying their update. In first line, the choice will be made between chemotherapy with carboplatin/paclitaxel or hormone therapy with progestin, depending on tumor characteristics (histological type, grade, expression of hormone receptors, rate of progression). In case of a dMMR tumors, the use of immunotherapy within the framework of a therapeutic trial is an option. Beyond first-line chemotherapy, current standard treatment consists of the combination of pembrolizumab and lenvatinib, regardless of MMR status. Close clinical and biological monitoring is however necessary given the potential toxicity. Chemotherapy retains its place either as monotherapy (paclitaxel or doxorubicin) in the event of failure or contraindication to pembrolizumab-lenvatinib, or in combination with carboplatin in the event of a long free interval and pMMR tumor. The numerous ongoing clinical trials evaluating new therapeutic targets or strategies adapted to molecular or histological types should allow further improvements the prognosis of patients with metastatic endometrial cancer.

Recommandations pour la pratique clinique Nice/Saint-Paul-de-Vence 2022–2023 : Diagnostic histomoléculaire des carcinomes de l'endomètre

French recommendations for clinical practice Nice-Saint-Paul de Vence 2022-2023: histomolecular diagnosis of endometrial carcinomas The characterisation of endometrial carcinomas has been recently modified and enriched by molecular classification, the integration of which now impacts therapeutic decisions on whether adjuvant therapy should be administered or not in localized tumors, and influences treatment selection in advanced disease. Mandatory information includes histological type according to WHO 2020 classification, histological grade, hormone receptors status and molecular classification, the main new elements to provide being analysis of MMR proteins, p53 status and POLE status in selected cases. Sampling and preparation of material must be performed adequately to allow complete analysis. Numerous markers can be used to better define histological type, distinguish between primary lesion or metastases, or provide prognostic information. Determination of MMR/MSI profile is complex but well defined by guidelines that precisely describe techniques to be used and interpretation rules. Knowledge of POLE status is useful to guide therapeutic strategy, especially to consider de-escalation in stages I and II, in particular in case of high grade and/or p53 mutated tumors. This is why indications of POLE determination must be well defined. Finally, oncogenetics consultation is recommended in dMMR tumors (except in case or MLH1 promoter methylation) and in patients with evocative familial history.

Recommandations pour la pratique clinique Nice/Saint-Paul-de-Vence 2022–2023 : prise en charge du cancer de l'endomètre localisé

Recommendations for clinical practice, Nice/Saint-Paul-de-Vence 2022-2023: Management of localized endometrial cancer Endometrial cancer is the most frequent gynecological cancers in industrialized countries and its incidence increases. The newmolecularclassification allows determination of the risk of recurrence and helps orienting therapeutic management. Surgery remains the cornerstone of treatment. Minimally invasive approach must be preferred for stages I and II. Surgery includes hysterectomy with bilateral adnexectomy, sentinel lymph node biopsy even in high risk diseases and omentectomy for non-endometrioid tumors (except in case of clear cells tumors). Fertility preservation can be proposed in low grade, stage I tumors without myometrial involvement. In stage III/IV disease, lymph node debulking without totallymphadenectomy is indicated. In case of peritoneal carcinomatosis, first-line cytoreductive surgery is recommended if complete resection can be achieved. Adjuvant therapy is not recommended in low risk tumors. In intermediate risk tumors, curietherapy is indicated. In tumors with high-intermediate risk, curietherapy and external radiotherapy are indicated according to prognostic factors (stage II, lymphovascular invasion); adjuvant chemotherapy can be considered on a case-by-case basis. In high risk tumors, chemotherapy and external radiotherapy are recommended using a concomitant or sequential approach.

Sarcomes du stroma endométrial de bas grade : référentiels de prise en charge du GSF-GETO/NETSARC+ et du groupe TMRG

Low-grade endometrial stromal sarcoma (LG-ESS) accounts for approximately 15% of all uterine sarcomas. Median age of patients is around 50 years and half of the patients are premenopausal. In all, 60% of cases present with FIGO stage I disease. Preoperatively radiologic findings of ESS are not specific. Pathological diagnosis remains essential. This review aimed to present the French guidelines for low grade ESS treatment within the Groupe sarcome français - Groupe d'étude des tumeurs osseuse (GSF-GETO)/NETSARC+ and tumeur maligne rare gynécologique (TMRG) networks. Treatments should be validated in multidisciplinary team involved in sarcomas or rare gynecologic tumors. Hysterectomy is the cornerstone of treatment for localized ESS, and morcellation should be avoided. Systematic lymphadenectomy in ESS does not improve the outcome and is not recommended. Leaving the ovaries in situ in stage I tumors could be discussed for young women. Adjuvant hormonal treatment could be considered, for two years for stage I with morcellation or stage II and livelong for stages III or IV. Nevertheless, several questions remain, such as optimal doses, regimens (progestins or aromatase inhibitors) and duration of therapy. Tamoxifen is contraindicated. Secondary cytoreductive surgery if feasible for recurrent disease, appears to be an acceptable approach. Systemic treatment for recurrent or metastatic disease is mainly hormonal, with or without surgery.

Gestational trophoblastic diseases and neonatal choriocarcinoma

Trophoblastic diseases include benign pre-tumor entities (hydatidiform moles) and malignancies called gestational trophoblastic tumors. Most of the latter arise after a hydatidiform mole and are referred to as post-molar trophoblastic tumors. Their diagnosis relies on elevated human chorionic gonadotrophin (hCG) levels following a mole, without the need for histological confirmation. Other forms, including choriocarcinoma, placental site trophoblastic tumor (PSTT), and epithelioid trophoblastic tumor (ETT), require histology; notably, PSTT and ETT are relatively resistant to chemotherapy and usually necessitate surgery. The management of post-molar tumors and choriocarcinomas is guided by the International Federation of Gynecology and Obstetrics prognostic score: low-risk cases are treated with monochemotherapy, whereas high-risk forms by polychemotherapy. In refractory disease, immune checkpoint inhibitors represent an emerging option. Gestational choriocarcinoma is characterized by its marked malignancy, aggressiveness, and ability to spread to the mother and fetus. Diagnosis is based on histology combined with abnormally elevated circulating or urinary levels of hCG. Neonatal choriocarcinoma, resulting from transplacental transmission, is exceptionally rare yet life-threatening. It typically manifests early in life, with hemorrhagic visceral metastases. Management, although non-standardized, generally involves platinum-based chemotherapy followed by possible surgical removal of residual lesions. Therapeutic intervention must be prompt and adapted to neonatal pharmacokinetics, while addressing the significant risk of hemorrhagic complications. This review summarizes current knowledges on the diagnosis and treatment of gestational trophoblastic diseases, with particular emphasis on gestational choriocarcinoma and its neonatal counterpart.
