ABSTRACT
OBJECTIVES:
To report the long-term results of prostate brachytherapy followed by external beam radiotherapy (EBRT) in men with a positive seminal vesicle biopsy (+SVB). PATIENTS ANDMETHODS:
In all, 1081 men with localised prostate cancer were treated with permanent brachytherapy, of which 615 had staging SVB and 53 (9.4%) were positive. Higher stage, Gleason score and PSA level were associated with a +SVB (P < 0.001). Patients with +SVB and negative laparoscopic pelvic lymph node dissection, bone and CT scans had 3 months of androgen-deprivation therapy (ADT) followed by 103 Pd implant to the prostate (dose 100 Gy) and proximal SVs, and 2 months later 45 Gy EBRT. ADT was continued for a median of 6 months (total ADT 9 months). The mean (range) follow-up was 9 (5-22) years.RESULTS:
Biochemical freedom from failure (computed by the Phoenix definition), freedom from metastasis, and cause-specific survival (CSS) for patients with a negative SVB (-SVB) vs +SVB at 15 years, was 76.3% vs 60.6% (P = 0.001), 95.4% vs 78.2% (P < 0.001), and 95% vs 70.4% (P < 0.001), respectively. Prostate cancer death occurred in 45 of 590 (7.6%) men with a -SVB vs eight of 25 (32%) with a +SVB (odds ratio 5.7, 95% confidence interval 2.35-13.9, P < 0.001). Cox proportion hazard rates (HRs) demonstrated Gleason score (P < 0.001, HR 1.9), stage (P = 0.010, HR 1.42), RT dose (P = 0.013, HR 0.991), and +SVB (P = 0.001, HR 4.48), as significantly associated with CSS.CONCLUSIONS:
Men with a +SVB have inferior CSS compared to those with a -SVB. However, a strategy that included a SVB in high-risk patients and implantation of the SVs in men undergoing combined therapy still yields favourable long-term results.Palavras-chave
