Clinical characteristics and treatment modalities in women with newly diagnosed advanced high-grade serous epithelial ovarian cancer in Taiwan

This study was designed to investigate the demographics, treatment patterns, and clinical outcomes of patients newly diagnosed with high-grade serous ovarian cancer (HGSOC) in 3 medical centers in Taiwan before the integration of poly (ADP-ribose) polymerase inhibitors in clinical practice. A retrospective analysis was conducted on data from patients diagnosed with HGSOC between January 2014 and December 2018 and followed-up for a minimum of 12 months after diagnosis. Descriptive statistics were used to analyze the data, while survival rates were evaluated using the Kaplan‒Meier method. There were 251 patients included in the analysis, and 98.8% received platinum plus paclitaxel chemotherapy (PPCT). Primary cytoreductive surgery (PCS) and interval debulking surgery (IDS) were performed in 78.9% and 17.1% of patients, respectively. The percentage of optimal surgery was higher in the IDS cohort than in the PCS cohort (83.8% vs. 53.6%). Bevacizumab was used as initiation therapy in 16.7% of patients, and maintenance therapy was administered in 6.8%. Advanced age, IDS, and suboptimal surgery were independent poor prognostic factors associated with lower overall survival (OS). Patients with optimal surgery had significantly lower OS and progression-free survival in the IDS cohort than in the PCS cohort. The predictive accuracy was good for OS at the 1-year follow-up. Advanced age, IDS, and residual disease are associated with poor OS in patients with HGSOC. Compared to PCS, IDS provides a higher likelihood of optimal surgery but results in a lower probability of survival for patients with HGSOC in Taiwan.

Long‐term outcomes of fertility‐sparing treatment in endometrial carcinoma and endometrial intraepithelial neoplasia: Recurrence risk factors over a 9‐year follow‐up

AbstractIntroductionFertility‐sparing treatments using oral progestins have demonstrated promising oncologic outcomes for endometrial intraepithelial neoplasia and early‐stage endometrial cancer. However, the high recurrence rate remains a major concern, and the literature on long‐term follow‐up outcomes is limited. This study aimed to identify recurrence risk factors by analyzing clinicopathological and molecular profiles in a cohort with a median follow‐up of 9 years.Material and MethodsThis retrospective study included patients under 45 years of age who were diagnosed with endometrial intraepithelial neoplasia or endometrial cancer and received fertility‐sparing treatments at our center between 2010 and 2021. Patients who achieved complete responses were categorized according to recurrence status. Demographic, clinical, and molecular data were compared between groups. The primary endpoint was to identify risk factors for recurrence; secondary endpoints assessed obstetric and oncologic outcomes in patients with relapse.ResultsOut of 40 patients, 8 underwent hysterectomy within 1.5 years, while 32 responded to treatment and continued follow‐up. The recurrence and non‐recurrence groups contained 20 and 12 patients, respectively, with a median follow‐up of 107.5 months (range, 35–175 months). Multivariate analysis showed that a family history of cancer (HR = 2.597, p = 0.039) and treatment with megestrol acetate as the initial therapy (HR = 3.130, p = 0.021) were independent risk factors for shorter time to recurrence. Although mismatch repair deficiency was positively correlated with recurrence, the association did not reach statistical significance (p = 0.057). Four out of 24 patients were upstaged after hysterectomy, and all were in the recurrence group. Nine patients (22.5%) achieved pregnancy, with three successfully conceiving after achieving complete response following retreatment.ConclusionsIn patients with long‐term follow‐up after fertility‐sparing treatment, a family history of cancer and initial treatment with megestrol acetate were significantly associated with recurrence.

Preoperative magnetic resonance imaging predicts clinicopathological parameters and stages of endometrial carcinomas

ABSTRACTBackgroundWe investigated the agreement and accuracy of preoperative magnetic resonance imaging (MRI) with postoperative pathological characteristics and stages of endometrial endometrioid carcinoma (EEC).MethodsWe recruited 527 women with EEC who underwent staging surgery at a single medical institution. The preoperative MRI, stages, and clinical and pathological parameters, including myometrial invasion (MI), cervical invasion (CI), adnexal metastasis (AM), intra‐abdominal metastasis, and pelvic and/or para‐aortic nodal metastasis, were recorded and analyzed. The agreement and accuracy between the preoperative MRI findings and these parameters and stages were assessed.ResultsThe rate of the preoperative MRI‐based clinical stage matching the postoperative surgical stage was 85.2% in International Federation of Gynecology and Obstetrics stage IA, 51.9% in stage IB, 35.5% in stage II, 5.3% in stage IIIA, 33.3% in stage IIIB, 28.6% in stage IIIC1, 64.3% in stage IIIC2, and 93.8% in stage IVB. The consistency between radiologists and pathologists was 80.5% for deep MI, 91.5% for cervical invasion, 92.2% for adnexal metastasis, 98.9% for intra‐abdominal metastasis, and 87.5% and 92.2% for pelvic and para‐aortic nodal metastases, respectively. The negative predictive value of intra‐abdominal metastasis was the highest with 99.8%.ConclusionsPreoperative MRI could be an excellent tool for routine preoperative assessment to predict pathological parameters and stages of EEC, especially in excluding intra‐abdominal metastatic disease.

Technique for inguino-femoral lymph node dissection in vulvar cancer: an international survey

Vulvar cancer is a rare disease and despite broad adoption of sentinel lymph node mapping to assess groin metastases, inguino-femoral lymph node dissection still plays a role in the management of this disease. Inguino-femoral lymph node dissection is associated with high morbidity, and limited research exists to guide the best surgical approach. To determine international practice patterns in key aspects of the inguino-femoral lymph node dissection technique and provide data to guide future research. A survey addressing six key domains of practice patterns in performing inguino-femoral lymph node dissection was distributed internationally to gynecologic oncology surgeons between April and October 2020. The survey was distributed using the British Gynecological Cancer Society, the Society of Gynecologic Oncology, authors' direct links, the UK Audit and Research in Gynecology Oncology group, and Twitter. A total of 259 responses were received from 18 countries. The majority (236/259, 91.1%) of respondents reported performing a modified oblique incision, routinely dissecting the superficial and deep inguino-femoral lymph nodes (137/185, 74.1%) with sparing of the saphenous vein (227/258, 88%). Most respondents did not routinely use compression dressings/underwear (169/252 (67.1%), used prophylactic antibiotics at the time of surgery only (167/257, 65%), and closed the skin with sutures (192 74.4%). Also, a drain is placed at the time of surgery by 243/259 (93.8%) surgeons, with most practitioners (144/243, 59.3%) waiting for drainage to be less than 30-50 mL in 24 hours before removal; most respondents (66.3%) routinely discharge patients with drain(s) in situ. Our study showed that most surgeons perform a modified oblique incision, dissect the superficial and deep inguino-femoral lymph nodes, and spare the saphenous vein when performing groin lymphadenectomy. This survey has demonstrated significant variability in inguino-femoral lymph node dissection in cases of vulvar cancer among gynecologic oncology surgeons internationally.

Consensus on surgical technique for sentinel lymph node dissection in cervical cancer

The purpose of this study was to establish a consensus on the surgical technique for sentinel lymph node (SLN) dissection in cervical cancer. A 26 question survey was emailed to international expert gynecological oncology surgeons. A two-step modified Delphi method was used to establish consensus. After a first round of online survey, the questions were amended and a second round, along with semistructured interviews was performed. Consensus was defined using a 70% cut-off for agreement. Twenty-five of 38 (65.8%) experts responded to the first and second rounds of the online survey. Agreement ≥70% was reached for 13 (50.0%) questions in the first round and for 15 (57.7%) in the final round. Consensus agreement identified 15 recommended, three optional, and five not recommended steps. Experts agreed on the following recommended procedures: use of indocyanine green as a tracer; superficial (with or without deep) injection at 3 and 9 o'clock; injection at the margins of uninvolved mucosa avoiding vaginal fornices; grasping the cervix with forceps only in part of the cervix is free of tumor; use of a minimally invasive approach for SLN biopsy in the case of simple trachelectomy/conization; identification of the ureter, obliterated umbilical artery, and external iliac vessels before SLN excision; commencing the dissection at the level of the uterine artery and continuing laterally; and completing dissection in one hemi-pelvis before proceeding to the contralateral side. Consensus was also reached in recommending against injection at 6 and 12 o'clock, and injection directly into the tumor in cases of the tumor completely replacing the cervix; against removal of nodes through port without protective maneuvers; absence of an ultrastaging protocol; and against modifying tracer concentration at the time of re-injection after mapping failure. Recommended, optional, and not recommended steps of SLN dissection in cervical cancer have been identified based on consensus among international experts. These represent a surgical guide that may be used by surgeons in clinical trials and for quality assurance in routine practice.
