Twenty-five patients with endocrine-refractory prostatic carcinoma were
treated with doxorubicin, 20 mg/m2 given weekly. All patients had prior
hormonal therapy (68% had two or more prior hormonal maneuvers), and 21
(84%) had prior therapeutic or palliative irradiation. Median Karnofsky
performance status at the time of entry was 70. Hemoglobin was less than
12.0 g/dL in 15 patients. Bidimensional tumors were present in 12 patients
in 19 disease sites; four of the 12 patients (33%) responded in eight of
the 19 sites (42%); and three of eight patients had a 75% decrease in
prostatic nodule size. Ten of 20 evaluable patients had an improvement of
20% or greater in Karnofsky performance status and 67% (14 of 21) had
marked improvement in pain. A greater than 50% reduction or normalization
of acid phosphatase occurred in 19% and of alkaline phosphatase in 53%. The
overall response rate by National Prostatic Cancer Project criteria was
84%. Gastrointestinal toxicity and alopecia were minimal and
myelosuppression was not life threatening in any patient.
