PD-1 axis blockade, in combination with chemotherapy, improves outcomes in advanced triple-negative breast cancer that is PD-L1 positive. The phase 3 KEYNOTE-522 trial now shows that the addition of pembrolizumab to chemotherapy improves pathological complete response rates regardless of PD-L1 status and appears to improve survival.
PD-1 轴阻断联合化疗可改善 PD-L1 阳性的晚期三阴性乳腺癌的结局。目前,III 期 KEYNOTE-522 试验表明,帕博利珠单抗联合化疗可提高病理完全缓解率,且不受 PD-L1 状态影响,并可能改善生存。
