NEJM:奥拉帕利辅助治疗BRCA阳性早期乳腺癌

2021-06-26 MedSci原创 MedSci原创

对于高危、HER-2阴性、BRCA1或BRCA2阳性早期乳腺癌患者,在完成基础治疗后,接受后续奥拉帕尼辅助治疗可降低患者侵袭性疾病或远端疾病转移风险

临床上,大约5%的乳腺癌患者携带BRCA1或BRCA2突变,这部分患者多有乳腺癌家族史、年龄较低、伴有对侧乳腺癌和卵巢癌,并且多被确诊为三阴性乳腺癌。聚腺苷二磷酸核糖聚合酶抑制剂(PARP)可通过合成致死性靶向同源重组修复缺陷性肿瘤。近日研究人员考察了奥拉帕尼对BRCA1或BRCA2突变早期乳腺癌患者的辅助治疗效果。

在本次III期临床研究中,研究人员招募人类表皮生长因子受体2(HER2)阴性的早期乳腺癌患者,患者伴有BRCA1或BRCA2突变,在接受局部治疗、辅助治疗或辅助化疗后复发风险较高。患者随机接受口服奥拉帕尼或安慰剂,持续1年。研究的主要终点是无侵袭性疾病生存。

共有1836名患者接受了随机分组,平均随访2.5年,奥拉帕利组3年无侵袭性疾病生存率为85.9%,安慰剂组为77.1%(差异8.8%,侵袭性疾病或死亡的危险比为0.58)。奥拉帕利组3年无病生存率为87.5%,安慰剂组为80.4%(差异7.1%,远端转移或死亡危险比为0.57)。与安慰剂(86名患者死亡)组相比,奥拉帕尼组的死亡率较低(59名患者死亡,死亡风险比为0.68),但差异不显著。研究中未发现新的安全性事件,没有严重不良事件或需特别关注的不良事件。

研究认为,对于高危、HER-2阴性、BRCA1或BRCA2阳性早期乳腺癌患者,在完成基础治疗后,接受后续奥拉帕尼辅助治疗可降低患者侵袭性疾病或远端疾病转移风险

恩杂鲁胺或阿比特龙治疗后进展的转移性去势耐药性前列腺癌患者,PARP抑制剂奥拉帕尼可显著改善患者的无进展生存期

Mol Cancer Ther:GnRH受体靶向抑制剂可联合奥拉帕尼治疗卵巢癌

EP-100是一种合成的可溶性多肽,特异性靶向癌细胞上的促性腺激素释放激素受体。为扩大EP-100的应用范围,Shaolin Ma等人尝试探索治疗卵巢癌的EP-100联合方法,并探索这种联合方案的潜在机制。在原位癌的小鼠模型中,EP-100可降低卵巢癌细胞的存活率并抑制肿瘤的生长速度。研究人员还分别检测了EP-100与顺铂、紫杉醇、阿霉素、托泊替康、奥拉帕尼等5种标准药物的联合疗效,发现EP-10

2019 ESMO胃肠癌世界大会:奥拉帕尼维持治疗改善了BRCA突变的转移性胰腺癌患者的无进展生存期

2019年欧洲肿瘤内科学会胃肠癌世界大会(ESMO-GI)上的研究显示,使用一线铂类化疗成功治疗后使用奥拉帕尼olaparib维持治疗,可显着改善BRCA突变的转移性胰腺癌患者的无进展生存期(PFS)。
