Perioperative Risk Stratification in Surgically Treated Endometrial Cancer: The Impact of Nutritional Status and Comorbidity Burden on Morbidity and Survival.
Article in Annals of surgical oncology, 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 compare outcomes between older (≥ 70 years) and younger (< 70 years) patients with surgically treated endometrial cancer, evaluating the Prognostic Nutritional Index (PNI), Systemic Immune-Inflammation Index (SII), and Age-Adjusted Charlson Comorbidity Index (ACCI).
methodsThis retrospective cohort study included 319 patients who underwent surgery at a tertiary center (2014-2024). Demographics, pathology, treatment, and outcomes were analyzed. Perioperative morbidity was graded (Clavien-Dindo). Frailty (ACCI), PNI, and SII were assessed. Overall survival and disease-specific survival were analyzed in parallel; Kaplan-Meier analyses were performed overall and stratified by stage and histology. Major morbidity was analyzed with multivariable logistic regression.
resultsOf 319 patients, 93 (29.2%) were aged ≥ 70 years. Older patients more frequently exhibited high-grade histology, advanced stage, ASA III-IV status, high ACCI, and low PNI. Admissions to the intensive care unit were higher in older patients, but major morbidity (4.3% vs. 3.5%; p = 0.60) and 30-day mortality (1.1% vs. 0.9%; p = 0.60) were comparable between groups. Low PNI demonstrated moderate discriminatory ability for major complications. In multivariable analysis, low PNI (odds ratio 5.78; p = 0.012) and ASA III-IV (odds ratio 3.89; p = 0.047) were independently associated with major morbidity, whereas age ≥ 70 was not. For overall survival, higher PNI remained protective (hazard ratio 0.48 per 5-point increase; p < 0.001) and ASA III-IV predicted worse outcomes (hazard ratio 3.80; p = 0.002); however, chronological age was not an independent predictor.
conclusionOlder age is associated with more aggressive tumor biology but not with higher rates of major complications. PNI and ASA class are independent predictors of major morbidity and survival and should be integrated into perioperative risk stratification rather than using chronological age alone.
