OBJECTIVES: Biochemical modulation (BM) was initially used to enhance the effect of 5-fluorouracil (5-FU) by modulating its pharmacological action with the addition of other drugs. BM with low-dose cisplatin and 5-FU or UFT has been examined in cases of advanced gastric or pancreas cancer and 30 to 40% response rates have been reported. In the present study, the effect of BM on hormone refractory prostate cancer (HRPC) patients was examined. METHODS: BM consisting of 5 mg/body of cisplatin 3 times per week and 300-450 mg of UFT/day was given to 30 HRPC patients (median and range of age: 66 and 52-72, respectively). The ECOG performance status was 0 to 1. Gleason score was 7 in 8 patients, 8 in 10 patients and 9 in 12 patients, respectively. The metastatic site was bone in 29 patients (extent of disease on bone scan [EOD] grade 1: 10, 2: 10, 3: 8, 4: 1), lymph node in 8 and liver in 1. RESULTS: Among the 29 patients assessable for bone metastasis, 5 (17%) obtained marked improvement on bone scan. One was EOD grade 4 (super bone scan) and 4 were EOD grade 1-3. Eight (28%) were stable and 16 (55%) progressed on bone scan. Among 8 patients with lymph node metastasis, 4 (50%) showed partial response and 4 (50%) progression. One patient with liver metastasis showed complete response. Fourteen (47%) out of 30 patients showed a PSA decline of 50% or greater. Their median response duration was 8 months (range; 2 to 44 months). Among the 25 patients assessable for bone pain, 7 (28%) improved, 12 (48%) remained stable and 6 (24%) progressed. A side effect of Grade II anemia was seen in one patient. CONCLUSION: BM is effective in almost half of hormone refractory prostate cancer patients.
