[Combination chemotherapy with 5-FU and low-dose CDDP for urogenital tumors]

Chemotherapy with 5-FU and low-dose CDDP, MTX or LV has not been fully evaluated in urogenital tumors. In a study of advanced renal cell carcinoma, the response rate of the combination of 5-FU, CDDP and IFN-alpha was 9%. In urinary bladder cancer, the combination chemotherapy with 5-FU and low-dose CDDP has been used as a radiosensitizer. This combination chemotherapy with radiation introduced a high response rate and has been used for the preservation of bladder function with minimum invasive surgery. There are very few effective chemotherapies for advanced androgen independent prostate cancer. However, some oral fluoripyrimidine, like UFT, was shown to be effective to some extent for prostate cancer in a phase II study. Thus, combination therapies of 5-FU and low-dose CDDP for prostate cancer as a biochemical modulator may be expected.
