Impact of lymph node staging on survival in presumed early-stage ovarian cancer: a multicentric retrospective study.
Article in Journal of gynecologic oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveThis study aimed to assess the impact of comprehensive staging on survival outcomes in this population.
methodsPatients 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.
resultsA 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.
conclusionExtensive 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.
