Methods From August 1995 to December 2007 80 patients with a symptomatic pelvic mass of metastatic colorectal cancer were treated with palliative RT at Samsung Medical Center. Initial presenting symptoms were pain 68 cases bleeding 18 cases and obstruction nine cases . The pelvic mass originated from rectal cancer in 58 patients 73 and from colon cancer in 22 patients 27 . Initially 72 patients 90 were treated with surgery including 64 complete local excisions 77 in colon cancer and 81 in rectal cancer. The total RT dose ranged 860 Gy median 36 Gy with Gy per fraction. When the a p for the tumor was assumed to be 10 Gy for the biologically equivalent dose BED the median RT dose was Gy10 . Twenty one patients 26 were treated with CCRT. Symptom palliation was assessed one month after the completion of RT. Results Symptom palliation was achieved in 80 of the cases. During the median follow-up period of five months 1-44 months 45 of the cases experienced reappearance of symptoms the median symptom control duration was five months. Median survival after RT was six months. On univariate analysis the only significant prognostic factor for symptom control duration was BED 40 Gy10 p and CCRT was a marginally significant factor p . On multivariate analysis BED and CCRT were significant prognostic factors for symptom control duration p . .
