To examine the association between the features of metabolic syndrome (MetS) (obesity, hypertension, diabetes mellitus, and dyslipidemia) and the risk of biochemical recurrence (BCR) after radical prostatectomy in patients with prostate cancer.
This study included 283 Japanese patients with localized prostate cancer who were treated with radical prostatectomy between 2008 and 2012. Their oncological outcomes and the prognostic significance of several clinicopathological factors, as well as the features of MetS, were analyzed.
Of 283 men who underwent radical prostatectomy, 49 (17.2%) subsequently developed BCR with a median postoperative follow-up of 14.8 months. Among the clinicopathological factors, prostate-specific antigen (PSA) level at diagnosis, pathological stage, pathological Gleason score, and lymph-node involvement were independent risk factors for BCR in multivariate analysis. In addition, the number of metabolic risk factors was also an independent risk factor for BCR.
The features of MetS were linked with poorer outcome after radical prostatectomy among Japanese men. Further investigations are needed to determine the effect of improving MetS on prostate cancer prognosis.
研究代谢综合征(MetS)(肥胖、高血压、糖尿病和血脂异常)特征与前列腺癌患者根治性前列腺切除术后生化复发(BCR)风险之间的关系。
本研究纳入了 2008 年至 2012 年间接受根治性前列腺切除术的 283 例局限性前列腺癌日本患者。分析了他们的肿瘤学结局以及几个临床病理因素的预后意义,以及 MetS 的特征。
在 283 例接受根治性前列腺切除术的男性中,49 例(17.2%)随后发生 BCR,术后中位随访时间为 14.8 个月。在临床病理因素中,诊断时 PSA 水平、病理分期、病理 Gleason 评分和淋巴结受累是多因素分析中 BCR 的独立危险因素。此外,代谢风险因素的数量也是 BCR 的独立危险因素。
代谢综合征的特征与日本男性根治性前列腺切除术后的不良结局有关。需要进一步研究以确定改善 MetS 对前列腺癌预后的影响。
