ASCO 2020:三阴性乳腺癌节拍化疗探索(SYSUCC-001研究)

中山大学肿瘤防治中心的袁中玉教授和王曦教授领衔的SYSUCC-001研究是第一个采取节拍化疗模式的研究,今年更是入选了ASCO口头报告。

中山大学肿瘤防治中心的袁中玉教授和王曦教授领衔的SYSUCC-001研究是第一个采取节拍化疗模式的研究,今年更是入选了ASCO口头报告。

研究对完成标准治疗的TNBC患者采用一年卡培他滨节拍化疗维持治疗。SYSUCC-001研究入组的三阴性乳腺癌患者没有经过筛选,直接加入了卡培他滨。在56.5个月的中位随访期间,卡培他滨组的5年DFS率明显优于观察组(83% vs 73%,HR 0.63;95%CI 0.42=0.96;p=0.027),绝对获益达到了10%。卡培他滨组的5年DDFS率也明显高于观察组(85% vs 76%,HR 0.56;95%CI 0.37-0.90;p=0.016)。

5年OS率分别为85%和81%,无统计学差异,但是也能看到有优效性的改善。仍然具有重要的临床意义,选择一个低毒、通用的卡培他滨小剂量节拍化疗的方案,确实是一个非常好的创新。

著名的CREAT-X研究探讨了卡培他滨辅助治疗用于术前新辅助化疗未达pCR患者的疗效与安全性,结果发现对于新辅助化疗后未达到PCR或淋巴结阳性的HER2阴性早期乳腺癌患者,术后再给予6~8个周期的卡培他滨的巩固治疗能显著提高5年DFS与OS,这项研究改变了我们的临床实践。SYSUCC-001这项研究采取卡培他滨节拍化疗的模式,一是控制用药间隔周期,二是减小用药剂量,因而比CREAT-X研究耐受性更好,不良反应以及并发症的发生率都很低。202例(91.4%)患者按计划完成了为期一年的卡培他滨治疗,说明患者依从性和顺应性都很好,这项研究从一定程度上会改变我们的临床实践,同时也需要我们在后续的临床实践中加以验证。
