评估哪些mCRPC患者更适合阿比特龙的模型

转移性去雄抵抗前列腺癌(mCRPC)代表前列腺癌的最后阶段。近年来,阿比特龙的开发显著提高了mCRPC患者的预期寿命。然而,存在显著的临床异质性,一些患者表现为疾病进展缓慢,而另一些患者则遭受着侵袭性的、迅速进展的疾病。如何来评估患者的预后,仍然是一个亟需解决的问题。

《欧洲泌尿外科杂志》近日发表了一项研究结果,该结果验证了预后模型,并评估发现模型对低风险患者从阿比特龙中获益最大。

方法

该研究是在COU-AA-302 试验中治疗的 mCRPC 患者进行了分析 (NCT00887198);使用的模型为 :

危险评分= -0.344 × 白蛋白 + 0.235 × 碱性磷酸酶 - 0.166 × 血红蛋白 0.408 LDH + 0.378 ×  NLR  +  0.381 × 骨转移灶数目  + 0.262 × 疼痛评分(根据疼痛量表的疼痛得分简表)  + 0.707 × POS  + 0.204  × LnPSA - 0.003 ×TDR(诊断开始治疗的时间单位为月) + 0.389 ×治疗(详见网址https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6888025/ 中的补充材料)

结果

共分析了 1088 名患者。风险评分与总生存期相关模型的AUC0.733。大多数患者处于低 (49%) 或中 (41%) 风险。风险类别与 OS 显着相关(风险比 HR:2.3),影像学无进展生存期(HR:1.7)和前列腺特异性抗原无进展生存期(HR:1.7)。低风险患者的生存率更高(HR:0.73),但在中等风险中相似(HR:0.97)和高风险(HR:1.35) 患者。阿比特龙与安慰剂相比,低风险患者的两年 OS 率为 82% 与 74%,中风险患者为 55% 与 52%,高风险患者为 28% 与 31%

结论

阿比特龙对该模型中低风险疾病患者的生存影响最大
