EXTENDED SURGERY FOR ADVANCED COLO-RECTAL CARCINOMA (STAGE IV AND V)
Two hundred fifty-five patients with colo-rectal carcinoma underwent operations in our department between January 1980 and December 1988. The five-year survival rate of stage IV patients (30 cases) was 58％, and the three-year survival rate of stage V patients (44 cases) was 8％. The study for the expression of blood group-related cancer-associated antigens (Le
a, CA19-9, etc.) in colo-rectal cancers using immunohistological method and a series of mouse monoclonal antibodies revealed that the stromal staining pattern of CA19-9 means high malignancy with poor prognosis. Nineteen patients with locally invading rectal cancer were submitted to total pelvic exenteration with urinary diversion. The operative mortality rate was 5.3％. A determinate 5-year survival rate of 4.5 was achieved. Fourteen patients with local recurrent lesions of rectal cancer following abdominoperineal resection were submitted to pelvic exenteration combined with sacral resection. Two patients are alive disease free for longer than four years at this writing. This operation assures a better quality of life, lessening of symptoms, disease control and, in selected patients, a cure.
