Abstract

Analysis of mRNA expression in ∼5,500 breast cancers showed upregulation in 38% of basal tumors and 38% of inflammatory breast cancers (IBC). Upregulation, associated with signs of strong cytotoxic local immune response, was associated with a better survival in the basal or triple-negative subtypes, and with a better pathological response to chemotherapy in these subtypes and IBC. Reactivation of dormant tumor-infiltrating lymphocytes (TILs) by PD1/PDL1-inhibitors represents a promising strategy in these aggressive tumors.

摘要

对约5500例乳腺癌的mRNA表达分析显示,38%的基底样肿瘤和38%的炎性乳腺癌(IBC)出现上调。上调与强烈的细胞毒性局部免疫反应迹象相关,与基底样或三阴性亚型的更好生存率以及这些亚型和IBC对化疗的更好病理反应相关。通过PD1/PDL1抑制剂激活休眠的肿瘤浸润淋巴细胞(TILs)是这些侵袭性肿瘤中有前景的策略。
