Intensity-Modulated Radiation Therapy vs. 3D Conformal Radiation Therapy for Squamous Cell Carcinoma of the Anal Canal.

Abstract

This study is the largest thus far to compare 3DCRT and IMRT for definitive treatment of anal cancer. Although long-term outcomes did not significantly differ based on RT technique, a marked decrease in adverse effects and the need for a treatment break was achieved with IMRT.
