Prolongation of radiotherapy (RT) in the treatment of numerous types of cancer has been shown to reduce overall survival (OS). Treatment delays are common in squamous cell carcinoma of the anus (SCCA) due to the toxicity of definitive chemoradiation (CRT). The effect of these delays on outcomes has not been well evaluated. This study investigated the effects of RT prolongation on OS in patients receiving CRT for SCCA.
