Impact of rectal gas evacuation on dosimetry and applicator displacement in cervical cancer brachytherapy.

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
objectiveThis study aimed to evaluate the impact of rectal gas evacuation on organ-at-risk (OAR) volumes, dose-volume histogram (DVH) parameters, and applicator displacement during cervical cancer brachytherapy.
methodsTwenty-one cervical cancer patients who received three-dimensional brachytherapy at our center between November and December 2024 and presented with rectal gas were retrospectively included. Planning computed tomography (CT) images were acquired before and after rectal gas evacuation to evaluate changes in rectal and bladder volumes, as well as radiation dose variations to OARs (bladder, rectum, sigmoid, and small intestine). Dosimetric parameters analyzed comprised D
resultsRectal volume decreased by 40.1% after gas evacuation, while bladder volume increased by 18.2%. D
conclusionsRectal gas evacuation results in a statistically significant and clinically relevant reduction in rectal volume and rectal dose, underscoring its importance as a routine clinical procedure. However, as it may induce millimeter-level applicator displacement with clinically measurable dosimetric consequences, careful monitoring is warranted, with post-evacuation replanning or, if necessary, applicator adjustment.
