OBJECTIVES: The optimal palliative treatment in patients with advanced hormone-resistant prostate cancer (AHRPC) is still under investigation. We studied the effect of epirubicin, alone or combined with medroxy progesterone acetate (MPA), in this particular patient group. The aim of the study was to investigate the feasibility of quality of life (QOL) measurement and to ascertain whether MPA added to epirubicin produces a better QOL than epirubicin alone. METHODS: Of 28 randomized patients with symptomatic AHRPC, 26 were eligible for the study. Fourteen of them received epirubicin (100 mg/m(2) i.v.) every 3 weeks in combination with an oral dose of 500 mg of MPA twice daily. Twelve patients received epirubicin alone. For the QOL assessment, the Rotterdam Symptom Checkliste was used. Toxic side effects of chemotherapy were assed by the WHO criteria. Subjective responses included performance status and pain score. RESULTS: Compliance in completing QOL questionnaires was high (87.5%). In none of the QOL domains studied did any of the patients, irrespective of their treatment, experience an improvement in their QOL. Moreover, after 12 and 24 weeks, patients in both treatment arms experienced a significant worsening of physical symptom distress when compared to study entry. Toxicity was moderate to severe. A biochemical response (drop in prostate-specific antigen of more than 50%) was observed in 5 out of 26 patients (19.1%) and a subjective response in 7 out of 26 patients (26.9%). The median survival for all patients was 30 weeks. There was no statistically significant difference between the two arms. Performance status and the global QOL as judged by the patients themselves were associated with the duration of survival. No relation was found between the initial observed subjective response and survival. CONCLUSIONS: The feasibility of measuring QOL in patients with symptomatic AHRPC is demonstrated in the present study. Subjective and biochemical responses were observed in both treatment arms, but these were not translatable as improved measured QOL domains.
