First birth after uterine transposition in low‐volume lymph node metastasis of cervical cancer: A long journey for success

AbstractLocally advanced cervical cancer poses a significant challenge to fertility‐sparing treatments. Pelvic radiotherapy impairs reproductive potential owing to ovarian, uterine, and endometrial side effects. This study presents a literature review of the main fertility‐sparing therapeutic alternatives for locally advanced cervical cancer and a case report of the first childbirth following uterine transposition for gynecological malignancies.

Uterine transposition for fertility and ovarian function preservation after radiotherapy

To evaluate the feasibility of uterine transposition as a method of preserving fertility and ovarian function after pelvic radiation. This prospective multicenter observational study included patients with non-gynecologic pelvic cancers who underwent pelvic radiation as part of their cancer treatment between June 2017 and June 2019. For inclusion in the study, patients were required to have normal menstrual cycles and hormone levels (follicle-stimulating hormone, luteinizing hormone, and estrogen) before treatment. Uterine transposition to the upper abdomen was performed prior to irradiation. Clinical examinations and Doppler ultrasonography were used to evaluate the gonadal vasculature post-surgery. The uterus was repositioned into the pelvis 2-4 weeks after radiation therapy or at the time of rectosigmoid resection in patients with rectal cancer who had undergone neoadjuvant treatment. Cancer treatment and follow-up were performed according to standard guidelines. Eight patients (seven with rectal cancer and one with pelvic liposarcoma) underwent uterine transposition at a median age of 30.5 years (range 19-37). The uterus was successfully preserved in six patients, accompanied by normal menses, hormonal levels, and vaginal intercourse after treatment. One patient with rectal cancer died of carcinomatosis 4 months after uterine transposition. One patient presented with uterine necrosis 4 days after uterine transposition, and the uterus was removed; however, one ovary was preserved. Cervical ischemia was the most common post-surgical complication in three (37.5%) patients. Three patients attempted to conceive, and two (66%) were spontaneously successful and delivered healthy babies at 36 and 38 weeks by cesarean section without complications. Uterine transposition is a feasible procedure for preserving gonadal and uterine function in patients requiring pelvic radiotherapy for non-gynecological cancer, with the potential for achieving spontaneous pregnancy and successful delivery.

Does sentinel node mapping impact morbidity and quality of life in endometrial cancer?

To evaluate the prevalence of post-operative complications and quality of life (QoL) related to sentinel lymph node (SLN) biopsy vs systematic lymphadenectomy in endometrial cancer. A prospective cohort included women with early-stage endometrial carcinoma who underwent lymph node staging, grouped as follows: SLN group (sentinel lymph node only) and SLN+LND group (sentinel lymph node biopsy with addition of systematic lymphadenectomy). The patients had at least 12 months of follow-up, and QoL was assessed by European Organization for Research and Treatment of Cervical Cancer Quality of Life Questionnaire 30 (EORTC-QLQ-C30) and EORTC-QLQ-Cx24. Lymphedema was also assessed by clinical evaluation and perimetry. 152 patients were included: 113 (74.3%) in the SLN group and 39 (25.7%) in the SLN+LND group. Intra-operative surgical complications occurred in 2 (1.3%) cases, and all belonged to SLN+LND group. Patients undergoing SLN+LND had higher overall complication rates than those undergoing SLN alone (33.3% vs 14.2%; p=0.011), even after adjusting for confound factors (OR=3.45, 95% CI 1.40 to 8.47; p=0.007). The SLN+LND group had longer surgical time (p=0.001) and need for admission to the intensive care unit (p=0.001). Moreover, the incidence of lymphocele was found in eight cases in the SLN+LND group (0 vs 20.5%; p<0.001). There were no differences in lymphedema rate after clinical evaluation and perimetry. However, the lymphedema score was highest when lymphedema was reported by clinical examination at 6 months (30.1 vs 7.8; p<0.001) and at 12 months (36.3 vs 6.0; p<0.001). Regarding the overall assessment of QoL, there was no difference between groups at 12 months of follow-up. There was a higher overall rate of complications for the group undergoing systematic lymphadenectomy, as well as higher rates of lymphocele and lymphedema according to the symptom score. No difference was found in overall QoL between SLN and SLN+LND groups.

Are endometrial cancer clinical practice management guidelines sufficiently consumer centric?

Sentinel lymph node mapping versus sentinel lymph node mapping with systematic lymphadenectomy in endometrial cancer: an open-label, non-inferiority, randomized trial (ALICE trial)

Growing evidence suggest that sentinel lymph node (SLN) biopsy in endometrial cancer accurately detects lymph node metastasis. However, prospective randomized trials addressing the oncological outcomes of SLN biopsy in endometrial cancer without lymphadenectomy are lacking. The present study aims to confirm that SLN biopsy without systematic node dissection does not negatively impact oncological outcomes. We hypothesized that there is no survival benefit in adding systematic lymphadenectomy to sentinel node mapping for endometrial cancer staging. Additionally, we aim to evaluate morbidity and impact in quality of life (QoL) after forgoing systematic lymphadenectomy. This is a collaborative, multicenter, open-label, non-inferiority, randomized trial. After total hysterectomy, bilateral salpingo-oophorectomy and SLN biopsy, patients will be randomized (1:1) into: (a) no further lymph node dissection or (b) systematic pelvic and para-aortic lymphadenectomy. Inclusion criteria are patients with high-grade histologies (endometrioid G3, serous, clear cell, and carcinosarcoma), endometrioid G1 or G2 with imaging concerning for myometrial invasion of ≥50% or cervical invasion, clinically suitable to undergo systematic lymphadenectomy. The primary objective is to compare 3-year disease-free survival and the secondary objectives are 5-year overall survival, morbidity, incidence of lower limb lymphedema, and QoL after SLN mapping ± systematic lymphadenectomy in high-intermediate and high-risk endometrial cancer. 178 participants will be randomized in this study with an estimated date for completing accrual of December 2024 and presenting results in 2027.

Cancer risk‐reducing surgery: Brazilian society of surgical oncology guideline part 1 (gynecology and breast)

AbstractBackgroundRisk‐reducing operations are an important part of the management of hereditary predisposition to cancer. In selected cases, they can considerably reduce the morbidity and mortality associated with cancer in this population.ObjectivesThe Brazilian Society of Surgical Oncology (BSSO) developed this guideline to establish national benchmarks for cancer risk‐reducing operations.MethodsThe guideline was prepared from May to December 2021 by a multidisciplinary team of experts to discuss the surgical management of cancer predisposition syndromes. Fourteen questions were defined and assigned to expert groups that reviewed the literature and drafted preliminary recommendations. Following a review by the coordinators and a second review by all participants, the groups made final adjustments, classified the level of evidence, and voted on the recommendations.ResultsFor all questions including risk‐reduction bilateral salpingo‐oophorectomy, hysterectomy, and mastectomy, major agreement was achieved by the participants, always using accessible alternatives.ConclusionThis and its accompanying article represent the first guideline in cancer risk reduction surgery developed by the BSSO, and it should serve as an important reference for the management of families with cancer predisposition.

Extraperitoneal laparoscopic pelvic lymphadenectomy for cervical cancer staging in twin pregnancy

Brazilian Society of Surgical Oncology consensus on fertility‐sparing surgery for cervical cancer

AbstractObjectiveSeveral controversies remain on conservative management of cervical cancer. Our aim was to develop a consensus recommendation on important and novel topics of fertility‐sparing treatment of cervical cancer.MethodsThe consensus was sponsored by the Brazilian Society of Surgical Oncology (BSSO) from March 2020 to September 2020 and included a multidisciplinary team of 55 specialists. A total of 21 questions were addressed and they were assigned to specialists' groups that reviewed the literature and drafted preliminary recommendations. Further, the coordinators evaluated the recommendations that were classified by the level of evidence, and finally, they were voted by all participants.ResultsThe questions included controversial topics on tumor assessment, surgical treatment, and surveillance in conservative management of cervical cancer. The two topics with lower agreement rates were the role of minimally invasive approach in radical trachelectomy and parametrial preservation. Additionally, only three recommendations had &lt;90% of agreement (fertility preservation in Stage Ib2, anti‐stenosis device, and uterine transposition).ConclusionsAs very few clinical trials have been developed in surgery for cervical cancer, most recommendations were supported by low levels of evidence. We addressed important and novel topics in conservative management of cervical cancer and our study may contribute to literature.

MILACC study: could undetected lymph node micrometastases have impacted recurrence rate in the LACC trial?

The etiology of inferior oncologic outcomes associated with minimally invasive surgery for early-stage cervical cancer remains unknown. Manipulation of lymph nodes with previously unrecognized low-volume disease might explain this finding. We re-analyzed lymph nodes by pathologic ultrastaging in node-negative patients who recurred in the LACC (Laparoscopic Approach to Cervical Cancer) trial. Included patients were drawn from the LACC trial database, had negative lymph nodes on routine pathologic evaluation, and recurred to the abdomen and/or pelvis. Patients without recurrence or without available lymph node tissue were excluded. Paraffin tissue blocks and slides from all lymph nodes removed by lymphadenectomy were re-analyzed per standard ultrastaging protocol aimed at the detection of micrometastases (>0.2 mm and ≤2 mm) and isolated tumor cells (clusters up to 0.2 mm or <200 cells). The study included 20 patients with median age of 42 (range 30-68) years. Most patients were randomized to minimally invasive surgery (90%), had squamous cell carcinoma (65%), FIGO 2009 stage 1B1 (95%), grade 2 (60%) disease, had no adjuvant treatment (75%), and had a single site of recurrence (55%), most commonly at the vaginal cuff (45%). Only one patient had pelvic sidewall recurrence in the absence of other disease sites. The median number of lymph nodes analyzed per patient was 18.5 (range 4-32) for a total of 412 lymph nodes. A total of 621 series and 1242 slides were reviewed centrally by the ultrastaging protocol. No metastatic disease of any size was found in any lymph node. There were no lymph node low-volume metastases among patients with initially negative lymph nodes who recurred in the LACC trial. Therefore, it is unlikely that manipulation of lymph nodes containing clinically undetected metastases is the underlying cause of the higher local recurrence risk in the minimally invasive arm of the LACC trial.

Reconsidering adjuvant radiotherapy in intermediate-risk cervical cancer: findings from the CIRCOL study group

To evaluate survival outcomes associated with intermediate-risk factors in patients who underwent radical hysterectomy for cervical cancer, with a focus on the role of adjuvant radiotherapy. A multicenter retrospective cohort database comprising 1280 patients who underwent radical hysterectomy for cervical cancer was analyzed. For inclusion, patients had tumors ≤4 cm (International Federation of Gynecology and Obstetrics 2018 stages Ia2-Ib2) and were treated surgically between January 2000 and December 2017. Patients with lymph node metastasis, positive surgical margins, or parametrial involvement were excluded. Intermediate-risk factors were defined as tumor size >2 cm to ≤4 cm, stromal invasion ≥10 mm, and presence of lymphovascular space invasion. A total of 759 patients met inclusion criteria, of whom 158 (20.8%) received external beam radiotherapy. Patients who received external beam radiotherapy were older, more often underwent open surgery, and exhibited a higher incidence of adverse pathological features, including larger tumors, deeper stromal invasion, and lymphovascular space invasion. In multivariate analysis, tumor size >2 cm (HR 5.25, 95% CI 1.86 to 14.8) and stromal invasion ≥10 mm (HR 2.68, 95% CI 1.14 to 6.30) were independently associated with increased recurrence risk. No variables were independently associated with cancer-specific mortality. The presence of ≥2 intermediate-risk factors significantly increased the risk of recurrence (HR 3.48, 95% CI 2.05 to 5.91) and cancer-related death (HR 2.47, 95% CI 1.04 to 2.89), regardless of radiotherapy use. Tumor size and depth of stromal invasion were associated with increased recurrence risks. Adjuvant radiotherapy was not associated with improved survival outcomes in patients with intermediate-risk features.

Surgery in Ovarian Cancer—Brazilian Society of Surgical Oncology Consensus

ABSTRACTSurgical management in epithelial ovarian cancer (EOC) has a significant impact on overall survival (OS) and progression‐free survival (PFS). The Brazilian Society of Surgical Oncology (BSSO) supported an expert‐led task force for consensus: the best EOC surgery is provided by experienced and specialized trained surgeons in cancer centers. Laparoscopic or radiological staging can predict the possibility of complete cytoreduction (CC0) and help to reduce unnecessary laparotomies. Carcinomatosis and nodal extension should be evaluated at imaging. Multidisciplinary input is essential for determining the need for the selection of patients for surgery and adjuvant chemotherapy in patients with EOC. The BSSO proposes quality assurance criteria and the need for national consensus. Genetic counseling was deemed mandatory for all patients with EOC. This consensus states the final recommendations from BSSO for the management of EOC.

Comparison of Two-Position and Four-Position Cervical Injection Techniques for Sentinel Lymph Node Mapping in Endometrial Cancer Using Methylene Blue

This clinical trial evaluates lymph node mapping in newly diagnosed endometrial cancer patients undergoing surgery. The standard technique uses a 2-point methylene blue cervical injection. The study aims to determine if increasing injection points improves mapping success.

Sentinel Node Mapping in High Risk Endometrial Cancer

This study will evaluate the role of systematic lymphadenectomy after sentinel node (SLN) mapping in high risk endometrial cancer (high grade histologies or deep myometrial invasion). The participants will be randomized in a non-inferiority controlled trial in 2 groups: SLN mapping or SLN mapping followed by systematic lymphadenectomy.
