Impact of Prolonged Surgical Waiting Time on 5-Year Progression-Free Survival in Patients With Endometrial Cancer.
Article in The journal of obstetrics and gynaecology research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
aimTo evaluate the impact of surgical waiting time (SWT) on 5-year progression-free survival (PFS). Secondary objectives were to evaluate 5-year overall survival (OS) and prognostic factors for recurrence and OS in endometrial cancer (EC), considering Thailand's Key Performance Indicator (KPI) recommending surgery within 4 weeks.
methodsThis retrospective cohort study included 377 patients with histologically confirmed EC who underwent primary surgery at Hatyai Hospital between October 2016 and September 2024. SWT was defined as the time from diagnostic biopsy to definitive surgery and categorized as early (≤ 4 weeks) or delayed (> 4 weeks). Survival outcomes were assessed using Kaplan-Meier curves and log-rank tests. Prognostic factors were analyzed using Cox proportional hazards models.
resultsThe median SWT was 32 days. Median follow-up was 23 months. Delayed surgery correlated with higher BMI, larger tumors, and increased recurrence (12.7% vs. 4.9%, p = 0.010). Advanced FIGO stage, non-endometrioid histology, grade 3 tumors, LVSI, and delayed SWT were significant recurrence risk factors. Multivariate analysis confirmed advanced stage (HR: 5.15, p < 0.001) and SWT > 4 weeks (HR: 3.22, p = 0.011) as independent predictors. Recurrence risk increased with longer delays (> 6 weeks: HR: 3.22; > 8 weeks: HR: 3.16). Kaplan-Meier curves showed significantly reduced PFS with prolonged SWT, while its effect on 5-year OS was not significant (p = 0.1).
conclusionsSurgical delays beyond 4 weeks were associated with reduced PFS and increased recurrence, supporting Thailand's KPI and underscores the importance of timely surgery. The short follow-up may limit interpretation of long-term outcomes. Longer follow-up is warranted to confirm these results.
