摘要

QuestionnnIn patients with locally advanced prostate cancer, does endocrine therapy plus radiotherapy reduce disease-specific mortality more than endocrine therapy alone? nnMethodsnnDesign: Randomized controlled trial (SPCG-7/SFUO-3 trial). Current Controlled Trials ISRCTN01534787.nnAllocation: Concealed.*nnBlinding: Unblinded.*nnFollow-up period: Median 7.6 years.nnSetting: 47 centers in Norway, Sweden, and Denmark.nnPatients: 880 men < 76 years of age who had histologically confirmed clinical stage T1b–T2, G2–G3, or T3, G1-3 prostate cancer (1992 TNM classification, World Health Organization grade), prostate-specific antigen (PSA) level 70 ng/mL ( 70 µg/L), no metastases on bone scan and pulmonary radiography, good performance status, and life expectancy > 10 years. Patients with nodal disease were excluded.nnIntervention: Endocrine therapy alone (n = 439) or with radiotherapy (n = 436). Endocrine therapy consisted of total androgen blockade (leuprorelin, 3.75 mg/mo or 11.25 mg/3 mo, and flutamide, 250 mg 3 times/d) for 3 months, then flutamide until progression or death. Standard 3-dimensional conformal radiotherapy was started at 3 months and consisted of 50 Gy to the prostate and seminal vesicles and 20 Gy boost to the prostate.nnOutcomes: Prostate-cancer–specific mortality. Secondary outcomes were all-cause mortality, PSA recurrence, and quality of life (European Organization for Research and Treatment of Cancer QLQ-C30 questionnaire).nnPatient follow-up: 99% (mean age 66 y, intention-to-treat analysis).
