[Successful combined treatment with maximal androgen blockade (MAB), intra arterial chemotherapy and radiation for advanced prostatic ductal adenocarcinoma : report of two cases].

The first case was in a 73-year-old man with macrohematuria. The second case was in a 59-year-old man with pollakiuria. Their serum prostate specific antigen levels were slightly elevated and urinary cytology was negative. Histological examination by prostatic needle biopsy and biopsy from bladder neck showed prostatic ductal adenocarcinoma. Clinical stage on computed tomography and magnetic resonance imaging was T4N0M0 in both cases. After 10-month maximal androgen blockade(MAB) and arterial chemotherapy using reservoir system, radiation therapy was performed. After that, low dose FP-chemotherapy(5-fluorouracil 600 mg/day, cisplatinum 10 mg/day) was performed for 28 days in the first case. At present, there are no signs of recurrence or metastasis in either case.
