Radiotherapy (RT) is a potentially effective method in the treatment of symptoms of rectal
carcinomas. Nevertheless, almost all the evidences about palliative RT in rectal cancer have
been published more than two decades ago and were based on 2D conventional RT, which is
nowadays no longer used. Consequently, prospective studies on the efficacy of 3D-RT in the
management of symptomatic rectal cancer are still lacking. The aim of this prospective study
was to assess the efficacy of palliative short-course 3D RT (SCRT) in patients with
symptomatic obstructive rectal cancer.
