D’Rummo KA, et al. - Among patients with muscle-invasive bladder cancer (MIBC) who received bladder-preserving radiotherapy (RT), researchers examined the link between facility RT case volume and overall survival (OS), as well as the link with adherence to National Comprehensive Cancer Network guidelines for bladder preservation. They identified the participants using the National Cancer Database. They stratified facilities into high-volume facility (HVF) or low-volume facility at the 80th percentile of RT case volume. This study included a total of 7,562 patients. The groups did not differ in terms of age, Charlson-Deyo score, T stage, or node-positive rates. Among patients with MIBC, improved OS and greater guideline-concordant management were achieved in correlation with treatment at an HVF.
