[Two-route chemotherapy under AT-II induced hypertension using totally implanted injection port system in liver metastases derived from digestive cancers].
Two-route chemotherapy (TRC) with intraarterial infusion of cis-diamminedichloroplatinum and intravenous infusion of sodium thiosulfate was carried out on 8 cases of digestive cancer with liver metastases, using totally implanted injection port system. The metastases occurred from gastric cancer in 3 cases and from colonic cancer in 5 cases. Computed tomography and/or ultra-sonography revealed an overall response rate of 50% (4/8). Complete response (CR) was obtained in two cases. The therapy was repeated 12 times in one case of gastric cancer with multiple liver metastases and 5 times in another rectal cancer with a solid metastatic tumor. In the latter case, a right hepatic lobectomy was performed thereafter. The histology of the hepatic tumor showed mucin lakes and necrotic lesions, and no viable cancer cells were observed. This mode of chemotherapy was therefore considered a useful measure for the treatment of liver metastases derived from digestive cancers. Furthermore, no serious side effects occurred.
