Abstract

Given that human cancer xenografts tend to retain chemosensitivities similar to the cancerous tissue of origin, human carcinoma xenografts grown in nude mice were tested for sensitivity to four drug protocols: doxorubicin at 5 mg/kg, i.v., q5d; irinotecan at 60 mg/kg, i.v., q4d; cisplatin 5 mg/kg, i.p., q7d; and topotecan 1.5 mg/kg, p.o., qd (5 of 7 days). Irinotecan and doxorubicin protocols either halted or caused significant regression of the breast cancer cell lines (MCF7, MDA-MB 231 and T47D). None of the protocols tested resulted in significant regression in the lung cancer xenografts (H460, A549 and H226) although both irinotecan and doxorubicin did halt growth of the H226 xenograft. The ability of the irinotecan treatment to cause regression of xenograft size in all three colon cancer cell lines (SW620, COLO205 and HT29) justifies further clinical trials of irinotecan as an especially promising drug for the treatment of colon cancer.
