Ther Adv Med Onco:骨转移对尿路上皮癌患者预后的预测意义

2022-05-08 xiaozeng MedSci原创

已发生骨转移的转移性尿路上皮癌患者的总生存期较短

在转移性尿路上皮癌 (mUC) 中,骨转移 (BM) 与显著的发病率和死亡率相关,但它们作为独立预后因素的预测意义仍未完全明确。

本研究旨在评估骨转移对采用以铂类为基础的化疗作一线治疗的转移性尿路上皮癌患者的总生存预后的影响。

纳入了于2005年1月-2018年1月期间在玛格丽特公主癌症中心、汤姆贝克癌症中心或交叉癌症研究所接受以铂类为基础的化疗的转移性尿路上皮癌患者,收集患者的病情、治疗和反应特征。采用Kaplan-Meier方法估算无进展生存期(PFS)和总生存期(OS)。

总体上,共纳入了376位患者(中位年龄 67岁,76%的男性,63%的患者的ECOG表现状态 0-1分,41%的患者存在骨转移)。所有患者都接受了一线铂类化疗。


受试患者的临床特征

中位随访了16.8个月(范围:2.2-218.3个月),有骨转移的患者的中位无进展生存期较无骨转移患者的短(4.9 vs 6.5个月,p=0.03),有骨转移的患者的中位总生存期也较无骨转移患者的短(8.8 vs 10.8个月,p=0.002)。


有无骨转移患者的无进展生存率和总生存率

在单变量分析中,ECOG表现状态 2-3分(p<0.001)、有骨转移(p=0.002)和白细胞计数≥11000个细胞/mm3(p=0.001)均与较差的生存预后相关。既往膀胱切除术(p<0.001)和治疗后无进展(病情稳定、部分或完全缓解)均与总生存期延长相关(p<0.001)。这些因素在多变量分析中仍存在显著性。

综上,在该回顾性研究中,已发生骨转移的转移性尿路上皮癌患者的总生存期较短,提示骨转移或可作为接受铂类一线化疗的转移性尿路上皮癌患者的独立的负性预测因素,还可作为未来转移性尿路上皮癌相关临床试验设计时的分层因素。
