Prevention of local symptoms in muscle invasive bladder cancer patients: clinical significance of local radiation therapy.

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
purposeTo evaluate the significance of local radiation therapy (LRT) for prevention of local symptoms (LSs) caused by muscle-invasive bladder cancer (MIBC).
methodsWe retrospectively reviewed the clinical records of 133 patients from 13 hospitals. MIBC patients with or without metastases who were treated with LRT alone from January 2015 through December 2020 were enrolled. Exclusion criteria were urinary diversion (UD) prior to LRT, non-MIBC, or lack of clinical information. LSs were defined as hematuria requiring invasive treatment or transfusion, UD after LRT, bladder tamponade, and opioid use for bladder pain.
resultsOne hundred fourteen patients were finally enrolled in the study. During the median follow-up period of 13.5 months, 30 patients (26.3%) had LSs. Risk factors of LSs in multivariate analysis were a prior history of non-MIBC (NMIBC) (hazard ratio [HR] 2.99; 95% confidence interval [CI], 1.36 to 6.56; P < 0.01), radiation dose of less than 50 Gray (Gy) (HR 3.99; 95% CI, 1.80 to 8.82; P < 0.01), and tumor stage 3 or more (HR 2.43; 95% CI, 1.14 to 5.21; P = 0.02). Risk factors of overall survival (OS) in multivariate analysis were being female (HR 3.32; 95% CI, 1.68 to 6.58; P < 0.01), an age-adjusted Charlson Comorbidity index of 6 or more (HR 2.19; 95% CI, 1.18 to 4.10; P = 0.01), distant metastases (HR 3.20; 95% CI, 1.39 to 6.58; P < 0.01), and tumor size of 40 mm or more (HR 2.38; 95% CI, 1.34 to 4.52; P < 0.01). Toxicity (all grades) occurred in 40.4% of the patients, 4.8% with grade 3 or more and 95.2% with lower grades.
conclusionsWe determined the risk factors for LSs in MIBC patients treated with LRT alone. An escalated-dose of 50 Gy or more may contribute to prevention of LSs caused by MIBC. Thus, dose-escalated LRT for MIBC patients who can expect favorable survival may be a good option to avoid future annoying LSs.
