[Long-term survival in a case of large bowel cancer--efficacy of CPT-11-based chemotherapy].

A 77-year-old woman underwent an ileocecal resection and a partial resection of the small intestine for cecal cancer. However, ileus caused by a recurrence in the small intestine was detected two years and four months postoperatively, so an ileal resection was performed. Furthermore, metastases to the lungs, lymph nodes, and peritoneum were detected, and CPT-11-based chemotherapy was administered. The patient was initially treated by combination therapy with a small dose of CPT-11 and CDDP. The combination drugs were changed to MMC, 5'-DFUR, etc. while the appearance of adverse reactions was monitored. Three years of continuous treatment served to prevent the proliferation of tumors. At present, TS-1 chemotherapy is ongoing. The results suggest that CPT-11-based chemotherapy can be continued by changing the combination of concomitant drugs while monitoring adverse reactions. It thus may be an effective regimen for advanced and recurrent large bowel cancer.
