Quality control strategies for head and neck brachytherapy (interventional radiotherapy).

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
Purpose: This study aimed to investigate quality control (QC) strategies to enhance treatment delivery in interventional radiotherapy (IRT) for head and neck (H&N) cancers, focusing on ensuring the accuracy of therapy while addressing specific challenges, such as catheter displacement and tube misconnection. Material and methods: A retrospective analysis was conducted among 30 patients treated with IRT for nasal vestibule or eyelid cancers at our institutional center from January 2022 to December 2023. All treatments involved 14 fractions over nine days. QC measures were implemented to monitor catheter placement and prevent misconnection, with daily visual checks and mid-course CT evaluations. Distance measurements between catheter markers were compared across scans, and variations exceeding 2 mm prompted re-planning. Statistical analyses included one-way Results: A total of 420 fractions were delivered, and 360 marker distance measurements were analyzed. No significant differences were observed between initial and mid-course CT scans (mean distances, 35.2 ±10.5 mm and 35.9 ±10.5 mm, respectively). However, in 16.6% of cases, re-planning was required due to catheter displacement or marker variation exceeding 2 mm. Notably, patients with nasal vestibule cancers demonstrated higher number of catheters and increased risk of displacement. Dosimetric evaluation confirmed significant dose distribution changes in a sub-set of cases, highlighting the clinical importance of QC. Conclusions: Quality control strategies are essential to ensure precise treatment delivery in H&N IRT, especially in complex anatomical sites and risk of catheter displacement. Implementation of systematic checks and re-planning criteria enhances patient safety and treatment efficacy. Further research is warranted to refine QC measures and evaluate their impact on clinical outcomes.
