Predictive clinicopathologic factors for para-aortic nodal involvement in endometrial carcinoma.
Article in BMC cancer, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundTo identify clinicopathologic risk factors predicting para-aortic lymph node (PALN) metastasis in patients with endometrial carcinoma.
methodsA retrospective analysis was conducted on 598 patients with FIGO 2009 stage I-III endometrial carcinoma who underwent comprehensive surgical staging, including pelvic and para-aortic lymphadenectomy, at Bursa Uludag University Hospital between January 2000 and May 2025. Demographic, surgical, and histopathological parameters were extracted from medical records. Univariable and multivariable regression analyses were performed to determine predictors of PALN metastasis.
resultsPALN metastasis was identified in 64 patients (10.7%). Isolated PALN involvement occurred in 3.5% of cases. On multivariable analysis, elevated preoperative CA-125 (> 35 U/mL) (OR 2.07, 95% CI 1.11-4.84), deep myometrial invasion (> 50%) (OR 2.62, 95% CI 1.09-6.30), lymphovascular space invasion (OR 1.91, 95% CI 1.12-4.75), and pelvic lymph node metastasis (OR 25.5, 95% CI 12.8-50.9) were independently associated with PALN involvement. Patients with pelvic nodal metastasis had a markedly increased likelihood of para-aortic spread.
conclusionsPara-aortic lymph node metastasis in endometrial carcinoma is independently associated with pelvic lymph node positivity, elevated preoperative CA-125, deep myometrial invasion, and LVSI. These parameters may guide risk stratification and support the development of predictive models to minimize unnecessary lymphadenectomy while ensuring accurate staging and tailored adjuvant therapy.
