Combined androgen blockade (CAB) is becoming standard treatment for patients with newly diagnosed advanced prostate cancer. This statement is based on the outcome and long-term evaluation of patients treated in prospective randomised trials. Particularly, patients with 'good' prognostic signs at the time of diagnosis benefit most from this approach. Patients with metastatic prostate cancer treated with CAB can be stratified on the basis of clinical prognostic parameters such as performance status, the presence or absence of pain, the levels of alkaline phosphatase, and the levels of prostate-specific antigen (PSA) during the first months of CAB: for combined androgen deprivation, if they fall in the good prognostic category (+/- 30-35% of the patients); for surgical castration and palliative treatment or (experimental) cytotoxic therapy if they belong to the poor prognostic category (+/- 20% of the patients), and, for initial CAB during the first 3-6 months of therapy, followed by an evaluation of the regression of PSA under therapy. If PSA normalises (rapidly) during this period, patients could be considered as good prognostic candidates and continue CAB. If PSA does not decrease or normalise sufficiently, patients might be classified as belonging to the poor prognostic category and should be treated with palliative measures and/or experimental cytotoxic therapy after (surgical) castration.
联合雄激素阻断(CAB)正成为新诊断的晚期前列腺癌患者的标准治疗方法。这一说法基于前瞻性随机试验中患者的治疗结果和长期评估。特别是,诊断时具有“良好”预后体征的患者从这种治疗方法中获益最大。接受CAB治疗的转移性前列腺癌患者可根据临床预后参数进行分层,如身体状况、是否存在疼痛、碱性磷酸酶水平以及CAB治疗头几个月期间的前列腺特异性抗原(PSA)水平:对于联合雄激素剥夺治疗,如果患者属于良好预后类别(约占患者的30 - 35%);对于手术去势及姑息治疗或(试验性)细胞毒性治疗,如果患者属于不良预后类别(约占患者的20%),并且对于治疗前3 - 6个月的初始CAB治疗,随后评估治疗期间PSA的下降情况。如果在此期间PSA(迅速)恢复正常,患者可被视为良好预后候选者并继续CAB治疗。如果PSA没有充分下降或恢复正常,患者可能被归类为不良预后类别,应在(手术)去势后采用姑息措施和/或试验性细胞毒性治疗。
