[A case of effective regimen of tegafur and uracil (UFT)/leucovorin (LV) plus irinotecan (CPT-11) for advanced rectal carcinoma with severe pelvic infiltration to be performed curative resection].

A 72-year-old man was admitted to our hospital, complaining of severe diarrhea. Computed tomography, barium enema and colonoscopy revealed a cysto-rectal fistula and massive invasion to middle rectum and retroperitoneal space from the main tumor in the upper rectum. Because of obstruction of passage of stool, sigmoid colostomy was performed. Oral UFT/LV+CPT-11 were undertaken after surgery for 4 cycles to remarkably reduce the tumor both clinically and on an outpatient basis. During this period, no side effect was detected, and a performance status (PS) of 0 has been maintained. As the result, radical resection was performed 5 months after the first operation. The histological effect was judged to be grade 2. Furthermore, no recurrence was recognized after 16 months postoperatively. Therefore, oral administration of UFT/LV+CPT-11 was considered as effective neoadjuvant chemotherapy for advanced rectal carcinoma, and this also could be a promising regimen to maintain the quality of life (QOL) for patients in ambulatory therapy.
