Acute and Late Rectal Toxicity Following Hypofractionated Radiotherapy in Patients With Prostate Cancer: Results of a Prospective Study.

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
BACKGROUND/
aimPrevious randomized clinical trials have shown that moderate hypofractionation has a non-inferior or even superior efficacy to conventionally fractionated external beam radiation therapy (EBRT) in low and intermediate-risk prostate cancer. We herein aimed to evaluate the acute and late gastrointestinal (GI) toxicity of hypofractionated radiotherapy (HRT) in a real-world setting. PATIENTS AND
methodsPatients with intermediate-risk prostate adenocarcinoma eligible to receive HRT were prospectively enrolled. All patients were submitted to rectoscopy after completion of HRT, every three months after radiotherapy for the first year and every six months for the second year. Toxicity events were classified as acute, when presenting during radiotherapy or within the first three months following its completion, and as late when appearing three months to three years post-HRT.
resultsTwenty prostate cancer patients participated in this study and received 22 sessions of HRT (5 sessions a week; 2.75 Gy per session) and an overall dose of 60.5 Gy. None of our patients developed acute GI toxicity; late GI toxicity (RTOG/EORTC grade 3 rectal bleeding) was observed in 1 patient only (1/20, 5%), at 6- and 12-months post-HRT. No rectal mucosa damage was observed on follow-up rectoscopy in the acute phase in any of our patients; five patients (5/20, 25%) developed late telangiectasias. Vienna retroscopy score (VRS) was 1 in 4/5 patients (80%) and 2 in 1/5 (20%).
conclusionMinimal radiation-induced rectal mucosal damage was observed in our patient population, and only as a late event, further attesting to the safety of HRT in this setting.
