Initial PSA >20 ng/mL is generally considered an adverse prognostic feature in prostate cancer (PCa). Our goals were to estimate the impact of radical prostatectomy (RP) on biochemical recurrence- (BCR-) free and cancer-specific survival (CSS) rates of PCa patients with PSA >20 ng/mL, and to identify patients with favorable oncological outcome. Using 20 ng/mL as a cut-point value, 205 PCa patients, who underwent RP, were stratified into two groups. Multivariate analysis was used to determine the significant outcome predictors among patients with PSA >20 ng/mL. Men in this group had significantly lower 10-yr BCR-free and CSS rates than patients with PSA ≤20 ng/mL (20.7% versus 79.6% (P < 0.001) and 65.0% versus 87.9% (P = 0.010), resp.). Pathological stage and lymph node status were found to be the only independent predictors of PSA failure. Patients with favorable combination of these variables (pT2, N0) had significantly longer 10-yr BCR-free and CSS rates (44.3% versus 0% (P = 0.001) and 100.0% versus 33.6% (P = 0.011), resp.). High PSA values do not uniformly indicate poor prognosis after surgery. Patients, who might benefit the most from RP, are those with organ confined PCa and negative lymph nodes.
前列腺特异性抗原(PSA)初始值>20 ng/mL通常被认为是前列腺癌(PCa)的不良预后特征。我们的目标是评估根治性前列腺切除术(RP)对PSA>20 ng/mL的PCa患者生化无复发生存率(BCR)和癌症特异性生存率(CSS)的影响,并识别出具有良好肿瘤学结局的患者。以20 ng/mL作为切点值,将205例行RP的PCa患者分为两组。采用多变量分析确定PSA>20 ng/mL患者的显著结局预测因素。该组男性的10年BCR和CSS率显著低于PSA≤20 ng/mL的患者(分别为20.7%对79.6%(P<0.001)和65.0%对87.9%(P = 0.010))。病理分期和淋巴结状态被发现是PSA失败的唯一独立预测因素。这些变量(pT2,N0)组合良好的患者10年BCR和CSS率显著更长(分别为44.3%对0%(P = 0.001)和100.0%对33.6%(P = 0.011))。高PSA值并不一致地表明手术后预后不良。可能从RP中获益最大的患者是那些肿瘤局限于器官且淋巴结阴性的患者。
