Timing of adjuvant radiotherapy for early-stage endometrial carcinoma: a single-center retrospective cohort 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
objectiveTo investigate the appropriate timing of radiotherapy (RT) after hysterectomy in women with early-stage endometrial cancer (EC).
methodsWe analyzed the data of 1,062 patients with early-stage EC who underwent postoperative RT at our hospital between April 1999 and November 2020. Restricted cubic spline were used to explore the relationship between the surgery-radiotherapy interval (SRI) and local recurrence-free survival (LRFS). The maximally selected rank statistics method was used to identify the optimal threshold for SRI. The overall survival (OS), disease-free survival (DFS), LRFS, and distant metastasis-free survival (DMFS) rates were estimated using the Kaplan-Meier method. Multivariate analysis was performed using the Cox proportional hazards regression.
resultsIn entire cohort, patients with SRI ≥42 days had worse survival. In multivariate analysis, SRI was an independent prognostic factor for OS (p=0.011), DFS (p=0.019), LRFS (p=0.013) and DMFS (p=0.050). However, in piecewise Cox regression, the significance of SRI for DMFS disappeared. In the subgroup analysis, the optimal cut-off value for SRI in the high-intermediate risk (HIR) and high-risk (HR) groups was 33 days. Multivariate analysis showed that SRI was an independent prognostic factor only for LRFS (p=0.033) and marginally associated with OS (p=0.055).
conclusionThe timing of postoperative RT is crucial in patients with early-stage EC. Adjuvant RT should be initiated as soon as the vaginal cuff is healed, while for HIR and HR patients, it should be initiated within 33 days.
