Prognostic significance of para-aortic node metastasis in endometrial cancer: Japanese Gynecologic Oncology Group Study JGOG2043 post hoc analysis.
Trial report in Journal of gynecologic oncology, 2025. 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 prognostic significance of para-aortic lymphadenectomy (PALX) and para-aortic lymph node metastasis in endometrial cancer (EC) patients at risk of post-operative recurrence.
methodsJapanese Gynecologic Oncology Group (JGOG) 2043 was a randomized controlled trial assessing the efficacy of adjuvant chemotherapy in EC patients at risk for post-operative recurrence. A retrospective analysis included patients who underwent pelvic lymphadenectomy (PLX) alone or both PLX and PALX in JGOG2043. Data on positive lymph nodes and other clinicopathological risk factors were collected.
resultsPLX and PALX were performed on 402 patients, while PLX alone was conducted on 250 patients. Evaluating the effect of PALX on survival was challenging through a comparison of the outcomes of the 2 cohorts since PALX was predominantly administered to higher-risk patients. Patients with 2 or more metastases in para-aortic nodes exhibited significantly poorer overall survival than those with no or 1 metastasis, respectively (p<0.001, p=0.031). Multivariate analysis revealed that 2 or more metastases in para-aortic nodes is independent risk factors for disease-free survival (hazard ratio [HR]=1.72; 95% confidence interval [CI]=1.10-2.72; p=0.019) and are marginally significant for overall survival (HR=1.58; 95% CI=0.92-2.72; p=0.096) compared to no or a single metastasis.
conclusionThe clinical relevance of PALX was challenging to evaluate in the JGOG2043 cohort; however, the presence of 2 or more para-aortic node metastases was identified as an independent unfavorable prognostic factor in EC patients at risk of recurrence.
