5-Fluorouracil + cisplatin + mitomycin C is a relatively most effective combination against xenograft lines of human colorectal cancer.
5-Fluorouracil (5-FU) has been an accepted effective against colorectal cancer, but combination regimens resulted in a lesser effect than 5-FU alone. The present study was designed to evaluate the efficiency of various combination chemotherapies, including 5-FU, on human colorectal cancer xenograft lines (CC-KK and RC-TK), which had been passed by transplantation in nude mice. Eight anticancer agents [5-FU, mitomycin C (MMC), adriamycin (ADR), 4'-epirubicin (EPIR), carboquone (CQ), cisplatin, carboplatin and etoposide (VP-16)] and their combinations were evaluated at 2-4 times the clinical dose. When the agents were administered singly, 5-FU, EPIR and CQ were effective against CC-KK, and 5-FU, MMC, EPIR, ADR, CQ and carboplatin were effective against RC-TK. Of the two-agent combinations including 5-FU, cisplatin + 5-FU was the most effective against both CC-KK and RC-TK. However, of the three-agent combinations, only cisplatin + 5-FU + MMC was more effective against both lines than cisplatin + 5-FU. These results suggest that cisplatin + 5-FU + MMC may be the most useful regimen against colorectal cancers in clinical application.
