[Analysis of clinical effects of a concurrent CDDP/5-FU therapy on inoperable colon cancer].

The mechanisms of synergic effects on cancer cells, the rational dose schedules resulting from these action mechanisms, and actual clinical results for inoperable colon cancer patients by a concurrent CDDP/5-FU therapy, are described. We analyzed the clinical results on the basis on the literature dealing with concurrent CDDP/5-FU therapy for inoperable colon cancer patients. This analysis suggested that some modified dose schedules of CDDP and 5-FU for inoperable colon cancer patients made no difference in response rates, survival times or adverse effects. Concurrent low-dose CDDP/5-FU therapy for inoperable colon cancer patients is now awaited in Japan.
