Targeting BRAF pathway in low-grade serous ovarian cancer

Mutations in genes encoding for proteins along the RAS-RAF-MEK-ERK pathway have been detected in a variety of tumor entities including ovarian carcinomas. In the recent years, several inhibitors of this pathway have been developed, whose antitumor potential is currently being assessed in different clinical trials. Low grade serous ovarian carcinoma, is a rare gynecological tumor which shows favorable overall survival, compared to the general ovarian cancer population, but worrying resistance to conventional chemotherapies. The clinical behavior of low grade serous ovarian carcinoma reflects the different gene profile compared to high-grade serous carcinoma:

Sentinel node mapping in endometrial cancer

Nodal status is one of the most important prognostic factors for patients with apparent early stage endometrial cancer. The role of retroperitoneal staging in endometrial cancer is controversial. Nodal status provides useful prognostic data, and allows to tailor the need of postoperative treatments. However, two independent randomized trials showed that the execution of (pelvic) lymphadenectomy increases the risk of having surgery-related complication without improving patients' outcomes. Sentinel node mapping aims to achieve data regarding nodal status without increasing morbidity. Sentinel node mapping is the removal of first (clinically negative) lymph nodes draining the uterus. Several studies suggested that sentinel node mapping is not inferior to lymphadenectomy in identifying patients with nodal disease. More importantly, thorough ultrastaging sentinel node mapping allows the detection of low volume disease (micrometastases and isolated tumor cells), that are not always detectable via conventional pathological examination. Therefore, the adoption of sentinel node mapping guarantees a higher identification of patients with nodal disease than lymphadenectomy. Further evidence is needed to assess the value of various adjuvant strategies in patients with low volume disease and to tailor those treatments also on the basis of the molecular and genomic characterization of endometrial tumors.

Malignant germ cells tumor of the ovary

Malignant ovarian germ cell tumors are rare and diverse malignancies, accounting for approximately 5% of all ovarian cancers. Primarily affecting young women, these tumors present unique challenges, particularly in balancing effective treatment with fertility preservation. Early diagnosis is common due to the rapid tumor growth and symptoms such as abdominal pain and distension, leading to favorable prognoses when combined with the high chemosensitivity of platinum-based regimens. Fertility-sparing surgery is the cornerstone of treatment for stage I disease, often followed by close surveillance to minimize the long-term toxicities of chemotherapy. Pathology is pivotal for diagnosis, incorporating immunohistochemical markers to differentiate malignant ovarian germ cell tumors subtypes, including dysgerminomas, yolk sac tumors, and immature teratomas. Advanced imaging modalities like ultrasound, magnetic resonance imaging, and computed tomography are essential for staging, monitoring treatment response, and detecting recurrences. Despite high cure rates, long-term follow-up is crucial to manage late toxicities, such as gonadal dysfunction and secondary malignancies. Recurrent malignant ovarian germ cell tumors present significant therapeutic challenges. High-dose chemotherapy with stem-cell transplantation offers promise in select cases, while the role of secondary cytoreductive surgery and radiotherapy is limited to specific indications. Emerging targeted therapies and novel approaches, such as KIT inhibitors for dysgerminomas with KIT mutations, remain experimental, with limited success reported so far. The rarity and heterogeneity of malignant ovarian germ cell tumors impede large-scale research efforts, underscoring the need for greater understanding of their molecular and genetic landscape to develop more effective and personalized therapies.

Ovarian Cancer Retrospective European (O'CaRE) study: first-line outcomes by number of risk factors for progression

Age-specific predictors of cervical dysplasia recurrence after primary conization: analysis of 3,212 women

This study aimed to identify predictors of recurrence/persistence of cervical intraepithelial neoplasia grade 2+ (CIN2+) lesion (r-CIN2+) after primary conization. Retrospective analysis involving all consecutive women having conization for CIN2+ between 1998 and 2018. The risk of r-CIN2+ was assessed using Kaplan-Meier and Cox models. Data of 3,212 women were retrospectively identified. After a mean follow-up of 47 (±22.2) months, 112 (3.5%) patients developed r-CIN2+. Mean time interval between prior conization and diagnosis of r-CIN2+ was 26.2 (±13.2) months. Via multivariate analysis, presence of high-risk human papillomavirus (HPV) types at the time of CIN2+ diagnosis, hazard ratio (HR)=3.40 (95% confidence interval [CI]=1.66-6.95) for HPV16/18 and HR=2.59 (95% CI=1.21-5.55) for HPV types other than 16/18, positive margins at primary conization, HR=4.11 (95% CI=2.04-8.26) and HPV persistence after conization, HR=16.69 (95% CI=8.20-33.9), correlated with r-CIN2+, independently. Considering age-specific HPV types distribution, we observed that HPV16/18 infection correlated to an increased risk of r-CIN2+ only in young women (aged ≤25 years; p=0.031, log-rank test); while in the older population (>25 years) HPV type(s) involved had not impact on r-CIN2+ risk (p>0.200, log-rank test). HPV persistence is the main factor predicting r-CIN2+. Infection from HPV16/18 has a detrimental effect in young women, thus highlighting the need of implementing vaccination against HPV in this population. Further prospective studies are warranted for tailoring clinical decision-making for post-conization follow-up on the basis of risk factors.

The future of gynecologic oncologic surgery: a narrative review of current surgical trials

Recent advances in gynecologic oncology have driven a paradigm shift toward less invasive, more personalized surgical approaches. This narrative review critically examines key ongoing international trials investigating innovative surgical strategies across vulvar, cervical, ovarian, and endometrial cancers, with a focus on improving oncologic outcomes while minimizing morbidity. In vulvar cancer, trials are exploring the use of neoadjuvant chemotherapy and the replacement of inguinofemoral lymphadenectomy with chemoradiation in selected patients. For cervical cancer, large multicenter randomized trials are evaluating the oncologic safety of minimally invasive hysterectomy, surgical staging for para-aortic disease, and robotic-assisted surgery. In the contest of ovarian cancer, randomized trials are assessing the role of lymphadenectomy in early-stage disease, the optimal timing of cytoreductive surgery (primary versus interval), and the potential benefits of hyperthermic intraperitoneal chemotherapy, even in cases of platinum-resistant recurrence. For endometrial cancer, both observational and interventional studies are investigating sentinel lymph nodes mapping and robotic-assisted hysterectomy as alternatives to traditional staging procedures. Collectively, these trials underscore the growing importance of individualized treatment strategies guided by disease stage, histologic subtype, response to neoadjuvant therapy, and patient-specific factors. While minimally invasive techniques and surgical de-escalation appear promising for selected patient populations, critical questions remain regarding long-term oncologic safety, cost-effectiveness, and the consistency of practice across institutions. This narrative review synthesizes current evidence and outlines how the outcomes of these pivotal studies are expected to influence future guidelines in gynecologic cancer surgery.

Comparison of ultrasound with computed tomography and whole‐body diffusion‐weighted MRI in prediction of surgical outcome using ESMO ‐ ESGO criteria in patients with tubo‐ovarian carcinoma: prospective ISAAC study

ABSTRACT Objective To test the non‐inferiority of extended abdominopelvic ultrasound examination compared with contrast‐enhanced computed tomography (CT) and whole‐body diffusion‐weighted magnetic resonance imaging (WB‐DWI/MRI) in discriminating preoperatively between resectable and non‐resectable disease based on the European Society for Medical Oncology (ESMO) and European Society of Gynecological Oncology (ESGO)‐defined criteria in patients with tubo‐ovarian carcinoma. Methods The Imaging Study on Advanced ovArian Cancer was a prospective multicenter observational study conducted in five European gynecological oncology centers. All centers had ESGO accreditation to perform advanced ovarian cancer surgery, and ultrasound examinations were performed by a European Federation of Societies for Ultrasound in Medicine and Biology level‐III examiner in a standardized manner. Included in the analysis were patients enrolled between 2020 and 2022 with suspected or histologically proven primary tubo‐ovarian (including peritoneal) carcinoma who, for the purposes of the study, underwent ultrasound and CT imaging, as well as WB‐DWI/MRI if available, prior to surgery. The index tests, which included the preoperative imaging modalities as well as intraoperative exploration at the start of surgery, supplemented by biopsy or follow‐up imaging for extra‐abdominal locations, evaluated the presence of disease at eight anatomical sites that, if infiltrated, would indicate non‐resectability of the tumor according to the ESMO‐ESGO criteria. Surgical outcome, described by the surgeons at the end of the procedure, was used as the reference standard and non‐resectability was defined as the presence of residual disease > 1 cm or when debulking surgery was not feasible. The area under the receiver‐operating‐characteristics curve (AUC) and F 1  score were used to assess the performance of the preoperative imaging methods and surgical exploration in discriminating between patients with resectable and those with non‐resectable disease, based on the ESMO‐ESGO criteria. We also calculated the percentage agreement between imaging findings and surgical exploration findings at the start of surgery, supplemented when applicable by biopsy or follow‐up imaging for extra‐abdominal locations, regarding the presence of tumor infiltration at each of the eight anatomical sites associated with non‐resectability. Results Of 279 patients enrolled during the study period, 242 were included in the final analysis. In the subgroup of 167 patients who underwent surgery and had been examined by all three imaging methods, the AUC of the three imaging modalities and surgical exploration for discriminating between resectable and non‐resectable disease based on the ESMO‐ESGO criteria was 0.835 (95% CI, 0.756–0.915) for ultrasound, for CT it was 0.754 (95% CI, 0.664–0.843), for WB‐DWI/MRI it was 0.720 (95% CI, 0.626–0.814) and for surgical exploration it was 0.952 (95% CI, 0.915–0.988). Ultrasound was not inferior to CT or WB‐DWI/MRI, based on the AUC and F 1 score, in discriminating between patients with resectable and those with non‐resectable tubo‐ovarian carcinoma. At surgical exploration, at least one non‐resectability criterion was present in 32.2% cases. The criteria observed most frequently at surgical exploration were small‐bowel involvement (23.6% of cases), diffuse deep infiltration of the root of the small‐bowel mesentery (18.2% of cases) and hepatic hilum involvement (5.4% of cases). The percentage agreement between ultrasound and surgical exploration in assessing the presence of disease in at least one of the eight anatomical sites that, if infiltrated, would indicate non‐resectability of tumor, was 83.9%, surpassing the percentage agreement with surgical exploration of both CT (77.7%) and WB‐DWI/MRI (75.8%). Conclusion When performed by an experienced examiner, ultrasound is not inferior to either CT or WB‐DWI/MRI in discriminating between resectable and non‐resectable disease in patients with tubo‐ovarian carcinoma, based on evaluation of the presence of the disease in at least one of eight anatomical sites that, if infiltrated, would indicate non‐resectability of the tumor. © 2025 The Author(s).
