目的:探讨前列腺癌根治术(RP)前系统免疫炎症指数(SII)、中性粒细胞和淋巴细胞比值(NLR)等炎症因子对前列腺癌根治术后Gleason评分(GS)和Gleason评分升级(GSU)的预测作用。方法:回顾性分析2019年8月至2024年3月本院201例行前列腺活检和前列腺癌根治术的患者资料。分别按RP GS分级(GS≤6、GS≥7)比较相关指标。采用受试者工作特征曲线(ROC)分析证实炎症因子SII、NLR及其联合总前列腺特异性抗原(tPSA)预测GS和GSU的判别能力,再通过单因素和多因素logistic回归分析,以评估炎症标志物与GS分级的相关性。结果:入选患者按GS分级分为低GS(GS≤6)组和高GS(GS≥7)组。经独立样本t检验,高GS组患者T3+T4患者比例高于低GS组(P=0.001),NLR(P=0.004)、SII(P=0<0.001)、tPSA (P=0.029)均高于低GS组,年龄、游离前列腺特异性抗原/总前列腺特异性抗原(f/tPSA)、淋巴细胞/单核细胞比值(LMR))两组间无显著统计学差异。ROC曲线分析结果显示,SII、NLR和tPSA的AUC分别为0.716(P<0.001)、0.651(P=0.002)和0.700 (P<0.001),阈值为493.33、2.43和8.99ng/mL。根据多因素logistic回归分析,NLR≥2.43(OR=0.762,95%CI:0.246~2.361,P=0.637),结果显示NLR与GS分级无统计学差异,SII≥493.33 (OR=4.554;95%CI:1.442~14.380,P=0.010),tPSA≥8.99ng/mL (OR=3.095;95%CI:1.468~6.523,P=0.003),SII和tPSA为预测GS升高的独立显著因素。SII、NLR与tPSA联合的AUC分别为0.741(P<0.001)和0.713(P=0.003)。GS≤6的患者共42例(51.85%)出现GSU。根据ROC曲线分析所得的阈值(SII:493.33、NLR:2.43、tPSA:8.99ng/mL)将患者分为高、低两组,高水平组GSU率显著高于低水平组,P值分别为<0.001,<0.001,0.001,<0.001,<0.001。结论: SII和NLR是预测GS和在活检GS≤6的局限性前列腺癌(PCa)患者中检测GSU的有用炎症生物标志物。
