Doxorubicin, mitomycin-C, and 5-fluorouracil (DMF) in the treatment of metastatic hormonal refractory adenocarcinoma of the prostate, with a note on the staging of metastatic prostate cancer.
Sixty-two patients with metastatic hormonal refractory adenocarcinoma of the prostate received a combination of doxorubicin, mitomycin-C, and 5-fluorouracil (DMF). Thirty (48%) of the patients achieved an objective response. Response criteria excluded disease "stabilization" as a manifestation of response. Four clinical prognostic categories were identified: osseous I (OI) had metastatic axial skeletal involvement (23 patients); osseous II (OII) had axial and extremity skeletaL involvement (18 patients); visceral I (VI) had pulmonary metastasis (9 patients); and visceral II (VII) had pulmonary metastasis and involvement of other viscera (12 patients). The 20 responding patients survived a median of 47.5 weeks, whereas the 32 nonresponding patients survived a median of 23.8 weeks (n = 0.002). Response rates were highest among patients with OI (52%) and VI (88%) disease; response rates were lower amont patients with OII (33%) and VII (33%) disease. Responding patients in each clinical category survived longer than nonresponding patients except for those patients with VII disease. The median duration of response for patients with OI disease was 11 months, for OII 9.5 months, for VI patients it was 6.5 months, and VII patients it was 5 months. DMF is an effective treatment of metastatic hormonal refractory prostate cancer, resulting in consistent objective responses. The staging system employed identifies four clinical categories of metastatic prostate cancer and allows for accurate comparison of diet and stratification of study populations.
