Are Uterine Manipulators Harmful in Minimally Invasive Endometrial Cancer Surgery? A Retrospective Cohort Study.
Article in Cancers, 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
objectiveThe objective of our study was to assess the oncological safety of uterine manipulators (UMs) in apparent early-stage (FIGO I-II 2009) endometrial cancer treated by minimally invasive surgery (MIS).
methodsOur single-center retrospective study includes patients who underwent endometrial cancer surgery for apparent early-stage disease by either laparoscopy or by robotic or laparoscopic-assisted vaginal hysterectomy from November 2012 to December 2020. Data on UMs, isolated tumor cells (ITCs), cytology, lymphovascular space invasion, free cancer cells in fallopian tubes, stage, histology and grade were collected. Primary and secondary outcomes were cancer recurrence and disease-specific death. Kaplan-Meier curves and multivariate logistic regression were used for statistical analysis.
resultsA total of 930 women with early-stage endometrial cancer were included; 789 (84.8%) had hysterectomy with a uterine manipulator and 141 (15.2%) without. A total of 88% had endometrioid histology, 71.6% were grade 1 and 95.7% had stage I disease. A higher risk of recurrence was observed with the Hohl manipulator (HR: 2.83. 95% CI: 1.004-7.98
conclusionsThe use of UMs in MIS for endometrial cancer was associated with higher rates of recurrence without affecting disease-specific death, except in high-grade histologies.
