title: [Cancer chemotherapy combined with a calcium antagonist in patients with hematologic malignancies and solid tumors resistant to standard chemotherapy].
abstract: Cancer chemotherapy combined with calcium-channel blockers was administered to seventeen evaluable patients with hematologic malignancy and solid tumor who became resistant to standard chemotherapies between November 1981 and June 1986 in Saitama Cancer Center. Nicardipine and diltiazem were used as the calcium-channel blockers, which were given orally or intravenously. Adriamycin and/or vinca alkaloids were mainly used as a cancer chemotherapy. Partial remission was attained in 3 of 6 patients with malignant lymphoma. Remission was attained in 2 of 7 patients with acute leukemia including acute transformation of chronic myelogenous leukemia (CML/BC), one complete remission with acute lymphocytic leukemia and one cytoreductive effect with CML/BC. One partial response and one minor response were obtained among 4 patients with solid tumor. The remission of these responders was of short duration. The most serious side effect caused by calcium-channel blockers was hypotension, which was dose-limiting and induced oliguria in 6 of 23 courses. In conclusion, the clinical impression obtained with regard to the effectiveness against chemotherapy-resistant malignancies of cancer chemotherapy combined with calcium-channel blockers was not good even though the overall remission rate was 41%.
