title: Quality of life of patients with newly diagnosed poor prognosis M1 prostate cancer undergoing orchiectomy without or with mitomycin C. Results from the EORTC Phase-III trial 30893.
abstract: OBJECTIVE
  To compare the quality of life (QL) of patients with poor prognosis M1 prostate cancer treated with orchiectomy alone (ORCH) or orchiectomy combined with adjuvant mitomycin C (MMC; 15 mg/m(2) i.v. q 6 weeks: ORCH+MMC; EORTC trial 30893).
  
  
  METHODS
  Patients with newly diagnosed M1 poor prognosis prostate cancer completed a truncated version of the EORTC QLQ-C30 (V 1.0) at randomization (baseline) and every 6-12 weeks thereafter until going off the protocol. Five ad hoc questions assessing lower urinary tract symptoms were included in the QL questionnaire.
  
  
  RESULTS
  At least one QL form was completed by 177 of the 189 patients included in the trial, with baseline questionnaires available for 113 patients (ORCH n = 52; ORCH+MMC n = 61). In both arms, pain and urinary dysfunction improved during treatment. Compared with patients from the ORCH arm, the use of adjuvant MMC was associated with a significant reduction in global health status/QL and with impairment in 7 of 11 QL dimensions covered by the questionnaire. Some improvement in QL was observed after discontinuation of MMC. A survival benefit was not observed in the ORCH+MMC arm.
  
  
  CONCLUSIONS
  Intravenous MMC (15 mg/m(2) q 6 weeks) cannot be recommended as adjuvant treatment in M1 poor prognosis prostate cancer due to its negative impact on QL and lack of efficacy. In general, QL assessments should be mandatory when adjuvant chemotherapy is evaluated in patients with metastatic prostate cancer.
