Eur Urol:多种组织生物标志物可独立和附加地预测前列腺癌病理结果

2020-11-16 AlexYang MedSci原创

区分慢性前列腺癌和侵袭性前列腺癌仍然是前列腺癌治疗决策的一个关键挑战。越来越多的生物标志物现在可以帮助解决上述挑战,但这些标记很少在同一患者中一起检查,从而确定它们潜在的附加价值。

区分慢性前列腺癌和侵袭性前列腺癌仍然是前列腺癌治疗决策的一个关键挑战。越来越多的生物标志物现在可以帮助解决上述挑战,但这些标记很少在同一患者中一起检查,从而确定它们潜在的附加价值。

最近,有研究人员确定两个先前验证过的血浆标志物(转化生长因子β1[TGFβ1]和白细胞介素-6可溶性受体[IL6-SR])和两个验证过的组织评分(转移性前列腺癌基因组评价工具[GEMCaP]和细胞周期进展[CCP]评分工具)是否能在预测前列腺切除术后不良病理的临床参数上有所改善,以及它们在具有异质性格林森等级的的肿瘤中有多大差异。研究人员收集了加州大学旧金山分校381例和华盛顿大学260例的石蜡固定前列腺切除组织和术前血浆样本。研究发现,357名男性在前列腺切除术时没有发生升级/上行性事件,236名男性发生了轻微事件,67名男性发生了严重事件。TGFβ1和IL6-SR均与任何升级/上行性事件无统计学显著关联。相反,在单变量分析中,从格里森模式3组织中获得的CCP和GEMCaP评分都与轻微和严重升级/上行性事件直接相关。两项评分相互之间具有较弱的相关性。在包括这两项评分的多变量分析模型中,CCP评分能够预测轻微升级/上行性(OR 1.62,95% CI 1.05-2.49)和严重升级/上行性(OR 2. 26,95% CI 1.05-4.90),p=0.04),GEMCaP评分也能预测轻微升级/(OR 1.05,95% CI 1.03-1.08)和严重升级/上行性(OR 1.07,95% CI 1.04-1.11),p < 0.01)。其他临床参数在该模型中不显著。在包括Gleason模式3和4升级的肿瘤中,GEMCaP和CCP评分在更高等级的肿瘤中倾向于更高。研究的主要的限制是使用前列腺切除组织的虚拟活检作为前列腺活检的代用品。

IL6-SR和TGFβ1水平在不同队列中的分布

最后,研究人员指出,基于DNA和RNA分析的生物标志物特征可显著且独立地预测接受前列腺切除术的临床低风险前列腺癌男性的不良病理。
