Eur Urol Oncol:甲氨蝶呤、长春碱、阿霉素和顺铂在肌层浸润性膀胱癌患者中的安全性和有效性分析

2022-07-16 AlexYang MedSci原创

确定了MIBC患者中,甲氨蝶呤、醋氨蝶呤、阿霉素和顺铂(MVAC)新辅助治疗的安全性和有效性与年龄的关系。

肌层浸润性膀胱癌(MIBC)的标准治疗(SOC)包括基于顺铂的新辅助联合化疗,之后进行根治性膀胱切除术。尽管有指南的建议,但往往由于对毒性的担忧,老年患者并不接受SOC。

近期,来自美国的研究人员在《Eur Urol Oncol》上发表文章,确定了MIBC患者中,甲氨蝶呤、醋氨蝶呤、阿霉素和顺铂(MVAC)新辅助治疗的安全性和有效性与年龄的关系

研究包括了2002年1月1日至2018年12月31日期间,在Fox Chase癌症中心治疗的186名MIBC患者,研究人员对他们进行了回顾性分析。入选条件为经组织学证实的肌层浸润性尿道癌的成年人。排除标准包括非尿道组织学证实,缺乏固有肌层的侵犯,以及原发性上行道或转移性疾病。干预措施为用aMVAC进行新辅助化疗。

研究人员将患者按年龄分层(<65岁,65-74岁,>75岁)。在基线和治疗后评估了肾功能,并对各年龄组的临床病理变量进行了比较来确定疗效。

研究结果发现,在单变量和多变量分析中,当患者按年龄分层时,在剂量减少、治疗中断、手术时间或不良事件方面,不同年龄分层之间没有统计学上的显著差异。由于研究为回顾性,无法获得完整数据。另外,老年患者的基线肾功能明显变差,且随着年龄的增长,肌酐清除率下降的百分比变大。研究人员还发现,无论年龄大小,MVAC的疗效都相当。

aMVAC治疗不同年龄组患者的GFR中值

综上所述,在该单中心回顾性研究中,MVAC治疗是安全的,并在不同年龄段的MIBC患者显示出疗效。另外,还应基于临床变量而非年龄来确定能够接受新辅助化疗的患者。
