中文摘要

本研究评估了 84 例局部晚期乳腺癌(LABC)患者新辅助化疗(NAC)前后乳腺组织中的TIL(肿瘤浸润淋巴细胞)比例及其对生存的影响。分别使用活检标本和手术标本测定 NAC 前后的 TIL 水平。NAC 前后 TIL 中位比例分别为 17.5% 和 5%,差异显著。NAC 前后 Ki-67 指数、分子亚型、NAC 前后 TIL 浓度以及术前残余癌负荷中的 TIL,均与病理完全缓解(pCR)显著相关。

具体而言,NAC 前 TIL 水平较高与 pCR 率较高相关。术后 Ki-67 指数和 pCR 可显著预测无病生存期(DFS);术后 Ki-67 指数也可显著预测总生存期。DFS 的独立预后因素为术后 Ki-67 评分(风险比 [HR]:6.16;p = 0.012)、NAC 后 TIL 评分(HR:0.42;P = 0.041)和 pCR(HR:0.10;P = 0.038)。

本研究证实,较高的 NAC 前 TIL 水平和较低的术后 TIL 水平可能是 DFS 较长的替代指标;术后 TIL 比例还可能预测 LABC 患者 NAC 后是否达到 pCR。

To evaluate the tumour-infiltrating lymphocyte (TIL) rates in breast tissue before and after neoadjuvant chemotherapy (NAC) and their impact on survival, eighty-four patients with locally advanced breast cancer (LABC) were assessed. Pre- and post-NAC TIL levels were determined using biopsy and surgical specimens, respectively. The median TIL rate was significantly different before (17. 5%) and after (5%) NAC. Pre- and postoperative Ki-67 index, molecular subtype, pre- and post-NAC TIL concentration, and preoperative residual-cancer-burden TIL were significantly associated with pathological complete response (pCR).

Specifically, higher pre-NAC TIL levels were associated with higher pCR rates. Postoperative Ki-67 index and pCR, and postoperative Ki-67 index were significant predictors of disease-free (DFS) and overall survival, respectively. The independent prognostic factors for DFS were postoperative Ki-67 score (hazard ratio [HR]: 6. 16; p = 0. 012), post-NAC TIL score (HR: 0. 42; P = 0. 041), and pCR (HR: 0. 10; P = 0. 038).

Our study confirms that higher pre-NAC and lower postoperative TIL levels may be surrogate factors for longer DFS, and postoperative TIL rate may predict post-NAC pCR in patients with LABC.
