Total Pelvic Exenteration for Primary Local Advanced Colorectal Cancer

Abstract

Total pelvic exenteration (TPE) is an ultraradical operative procedure for locally advanced pelvic tumors with high morbidity and mortality rates. We retrospectively reviewed the results of TPE for primary locally advanced colorectal cancer in terms of mortality, morbidity, and long-term survival. Of 2952 patients with colorectal cancer, 50 underwent TPE for primary locally advanced colorectal cancer between 1986 and 1995. There was one operative death (2%). The other 49 cases were entered into a retrospective study. Thirty-two cases (65%) showed involvement of one or more adjacent organs. Thirty-one patients (97%) had urologic organs invaded by tumor. The overall 5-year survival rate was 49% and the overall morbidity was 37%. The survival rate for stage II was 62%, and that for stage III was 35%; there was no survival in stage IV. Early morbidity was noted in 24% of patients; late morbidity, in 15%. TNM stage appeared to be the only independent factor for survival (p = 0.022). Our study showed that TPE can be performed with relatively low operative mortality and acceptable morbidity. With thorough preoperative evaluation and adequate surgical dissection, satisfactory outcomes for a primary locally advanced colorectal cancer can be achieved, especially at the earlier stages.
