Abstract

The delineation of clinical target volume (CTV) is a critical step in planning conformal radiotherapy for rectal cancer.Several guidelines suggest different subvolumes and anatomical boundaries in radiotherapy for rectal cancer, potentially leading to a misunderstanding of CTV definition.This article reviews recent advances in the delineation of CTV in radiotherapy for rectal cancer.
