Previous studies investigating prostate cancer (PCa) features in younger men have reported conflicting findings. This study aimed to investigate pathologic outcomes and biochemical recurrence (BCR) status in younger men who underwent radical prostatectomy (RP) for PCa. Records of 2057 patients who underwent RP at Seoul National University Bundang Hospital (Seongnam, Korea) between 2006 and 2015 were reviewed; patients were divided according to age into the younger and older groups (men aged ≤50 and >50 years, respectively). Postoperative BCR status and functional outcomes and clinicopathologic features were compared between both groups. All analyses were repeated after propensity score matching. Younger men were more likely to have low-risk disease (P < 0.001), lower pathologic Gleason score (P < 0.001) and pathologic stages (P < 0.001) than older men. The pathologic Gleason score (P = 0.002) and rates of extracapsular extension (P = 0.004) were lower in younger men after propensity score matching. In multivariate analysis, age at RP was not an independent predictor of BCR-free survival after RP (P = 0.669). Moreover, at 1 year after RP, younger men with preoperative 5-item International Index of Erectile Function score ≥22 (n = 228) showed more favorable results for urinary continence (defined as nonuse of pads daily) (99.4% vs 95%, P = 0.009) and erections sufficient for vaginal intercourse (81.8% vs 55.5%, P = 0.001). Younger men had more favorable clinicopathologic features at RP than their older counterparts. Although age was not an independent predictor of BCR status outcome, younger men had better functional outcomes following RP.
先前研究前列腺癌(PCa)在年轻男性中的特征报告存在矛盾的发现。本研究旨在调查接受根治性前列腺切除术(RP)治疗 PCa 的年轻男性的病理结局和生化复发(BCR)状态。回顾了 2006 年至 2015 年间在首尔国立大学盆唐医院(韩国城南)接受 RP 的 2057 例患者的记录;根据年龄将患者分为年轻组和老年组(分别为年龄≤50 岁和>50 岁的男性)。比较了两组患者的术后 BCR 状态和功能结局以及临床病理特征。所有分析均在倾向评分匹配后重复。年轻男性更可能患有低危疾病(P<0.001)、较低的病理 Gleason 评分(P<0.001)和病理分期(P<0.001)。在倾向评分匹配后,年轻男性的病理 Gleason 评分(P=0.002)和包膜外延伸率(P=0.004)较低。多变量分析显示,RP 时的年龄不是 RP 后 BCR 无复发生存的独立预测因素(P=0.669)。此外,在 RP 后 1 年,术前 5 项国际勃起功能指数评分≥22 的年轻男性(n=228)在尿控(定义为每日不使用护垫)方面表现出更有利的结果(99.4% vs 95%,P=0.009)和阴道性交足够的勃起(81.8% vs 55.5%,P=0.001)。年轻男性在 RP 时具有比老年患者更有利的临床病理特征。尽管年龄不是 BCR 状态的独立预测因素,但年轻男性在 RP 后具有更好的功能结局。
