[A new modality of locoregional chemotherapy based on biochemical double modulation of 5-fluorouracil with both leucovorin and cisplatin against liver metastases of colorectal cancer].
A new modality of locoregional chemotherapy based on biochemical double modulation of 5-fluorouracil (FU) with both leucovorin (LV) and cisplatin (CDDP) against liver metastases of colorectal cancer was devised. The schedule for the locoregional therapy was as follows; bolus infusion of LV (6 mg/body) followed by 30-minute infusion of CDDP (10 mg/body) and 30-minute infusion of 5-FU (250 mg/body). Four colorectal cancer patients with numerous metastases to both lobes of liver were given intraarterial administration of above anticancer drugs every 1-2 weeks after resection of primary lesions. On the one hand, 3 colorectal cancer patients, who developed a few metastases to both lobes of liver, were treated preventively by the same schedule every 2-3 weeks after the resection of metastatic tumors. As for the clinical (radiographic) response, complete response and partial response were observed in 1 and 2 of 4 patients, respectively. The response rate was 75%. No new lesions appeared for over 1 year by the preventive treatment in 2 of 3 patients, whereas new lesions appeared in one patient at 3 months after discontinuation of treatment because of mild toxicity. The toxicity, however, was within acceptable limits. These results indicated that biochemical double modulation of 5-FU with both LV and CDDP is a very promising locoregional chemotherapy against liver metastases of colorectal cancer.
