BMJ:保乳手术术中放疗治疗早期乳腺癌

2020-08-22 MedSci原创 MedSci原创

对于可以接受保乳治疗的早期乳腺癌患者,术中接受单次放疗的治疗效果与术后体外放射治疗相当,并且非乳腺癌死亡率较低

近日研究人员考察了乳腺癌患者肿瘤切除术中单剂量放疗的效果和安全性。

 

研究在英国、欧洲、澳大利亚、美国和加拿大等10个国家的32个中心开展,2298名年龄在45岁及45岁以上的女性乳腺癌患者参与,患者患有3.5厘米以下的浸润性导管癌,CN0-N1期,符合保乳治疗条件,随机分为靶向术中放疗组(TARGIT-IORT)或术后体外放射治疗组(EBRT)。EBRT组接受3-6周的全乳腺放射治疗,TARGIT-ORT组在肿块切除术后立即接受放疗,且80%的患者仅接受这一次放疗。研究的主要终点为5年局部复发率和长期生存率,非劣性边界为2.5%。

TARGIT-IORT组包含1140名患者,EBRT组包含1158名患者。研究认为TARGIT-IORT的治疗效果并不劣于EBRT:5年随访时,TARGIT-IORT组的局部复发率为2.11%,而EBRT为0.95%(差异为1.16%)。完全统计在治疗后最初的五年的数据,与EBRT相比,TARGIT-IORT额外报告了13例局部复发(24/1140 vs 11/1158),但死亡人数减少了14例(42/1140 vs 56/1158)。

长期随访(中位数8.6年,最大18.90年)表明,组间局部无复发生存率(危险比1.13),保乳手术生存率(0.96),无远端转移生存率(0.88),总体生存率(0.82)和乳腺癌死亡率(1.12)无显著差异,但TARGIT-IORT组其他原因的死亡率显著降低(0.59)。

对于可以接受保乳治疗的早期乳腺癌患者,术中接受单次放疗的治疗效果与术后体外放射治疗相当,并且非乳腺癌死亡率较低。
