2021-08-06肿瘤情报组原创:医学界肿瘤频道携带生殖系/体细胞BRCA1/BRCA2突变(g/sBRCA1/2)是胰腺导管腺癌(PDAC)的独特生物学亚组。近日有研究发现:在具有双等位基因状态的g/sBRCA1/2突变的患者中,铂类和PARP抑制剂提供了可观且持久的获益。 在2011年1月至2020年6月期间,共确定了136例g/sBRCA1/2患者。对于接受一线铂类药物治疗的IV期疾病患者,双等位基因患者(n=39)的中位OS为26个月(95%CI,20-52个月),杂合子患者(n=4)为8.66个月(95%CI,6.2个月至未达到)。对于接受PARP抑制剂治疗的患者,双等位基因患者(n=25)的中位OS为26.5个月(95%CI,24-53个月),杂合子患者(n=2)的中位OS为8.66个月(95%CI,7.23个月至未达到)。参考文献 共4篇 [1]Updated Overall Survival Data and Predictive Biomarkers of Sintilimab Plus Pemetrexed and Platinum as First-Line Treatment for Locally Advanced or Metastatic Non-squamous NSCLC in the Phase III ORIENT-11 Study.From https://www./article/S1556-0864(21)02330-3/fulltext [2]Ji Y,Du X,Zhu W,et al.Efficacy of Concurrent Chemoradiotherapy With S-1 vs Radiotherapy Alone for Older Patients With Esophageal Cancer:A Multicenter Randomized Phase 3 Clinical Trial.JAMA Oncol.Published online August 05,2021.doi:10.1001/jamaoncol.2021.2705 [3]Parisa Momtaz MD,Catherine A.O’Connor,Joanne F.Chou MPH,Marinela Capanu PhD,Wungki Park MD,Chaitanya Bandlamudi PhD,Michael F.Berger PhD,David P.Kelsen MD,Pancreas cancer and BRCA:A critical subset of patients with improving therapeutic outcomes.First published:05 August 2021 https:///10.1002/cncr.33812 [4]https://mp.weixin.qq.com/s/5Wcr-QwDmZ8DLE8VYTp5dQ 仅供医学人士参考
