Impact of lymph node staging on survival in presumed early-stage ovarian cancer: a multicentric retrospective study

This study aimed to assess the impact of comprehensive staging on survival outcomes in this population. Patients who underwent surgery for epithelial ovarian cancer in one of the 14 Francogyn cancer centers between 2000 and 2020 were included in the study. The primary analysis evaluated the impact of lymphadenectomy on overall survival and recurrence-free survival. Lymph node count was analyzed as a continuous variable, and its association with survival, considered as a continuous outcome was assessed using linear regression (secondary analysis). Survival was compared using the log-rank test, and multivariate analysis was performed using a Cox model. A total of 467 patients with presumed early-stage epithelial ovarian cancer were included, of which 198 underwent complete lymphadenectomy and 266 did not. No significant association was found between lymph node staging and survival in the primary analysis, possibly due to limited statistical power and a selection bias, as patients without lymphadenectomy had more favorable disease profiles (p=0.600 and p=0.700, respectively). Complete lymphadenectomy was associated with a significantly higher risk of complications (34.5% vs. 14%, p<0.001). In secondary analysis, the number of para-aortic lymph nodes harvested was identified as an independent predictor of both overall survival and recurrence-free survival (p=0.007 and p=0.002, respectively). Histological characteristics and adjuvant chemotherapy also showed a significant correlation with improved survival outcomes. Extensive para-aortic lymphadenectomy in early-stage epithelial ovarian cancer is associated with better overall and recurrence-free survival but comes with an increased risk of complications.

Comparison of survival outcomes between laparoscopic and abdominal radical hysterectomy for early-stage cervical cancer: A French multicentric study

A recent randomized controlled trial has reconsidered the use of laparoscopy for treating patients with early-stage cervical cancer with radical hysterectomy (RH). We aimed to evaluate if surgical approach had an impact on surgical and oncological outcomes in these patients in a French setting. Data of 1706 patients with cervical cancer treated between 1996 and 2017 were extracted from maintained databases of 9 French University hospitals. Patients, with FIGO stage IA2 to IIB tumors, treated by radical hysterectomy were selected for further analysis. A propensity score matching was used with a ratio of 2:1 in favor of laparoscopic approach was used. The Kaplan Meier method was used to estimate the survival distribution. 34 patients treated with laparotomy were matched with 61 patients treated by minimally invasive surgery (MIS). There was no difference regarding overall survival (91 % vs 81 %, p > 0.05) or disease-free survival (82 % vs 78 %, p > 0.05). There was no difference regarding surgical outcomes with no excess of postoperative complication in patients with MIS. Hospital stay was significantly longer in patients operated on laparotomy. In our study, there was no evidence of a difference in survival between minimally invasive surgery and laparotomy in patients treated with radical hysterectomy for early-stage cervical cancer.
