中文摘要

TIL(肿瘤浸润淋巴细胞)与HER2阳性乳腺癌患者接受新辅助化疗和trastuzumab后的结局相关。然而,在双重HER2靶向治疗背景下,TIL是否可作为预后和/或预测性生物标志物仍不清楚。

本研究评估TRAIN-2试验中389例II–III期HER2阳性乳腺癌患者的TIL与病理应答(pCR)及浸润性无病生存期(IDFS)的关系;患者接受含蒽环类或不含蒽环类化疗联合trastuzumab和pertuzumab的新辅助治疗。尽管TIL与pCR无显著关联,TIL评分≥60%的患者3年IDFS为100%(95% CI 100–100),无论激素受体状态、淋巴结分期及是否达到pCR均如此。

此外,在激素受体阳性患者中,将TIL作为连续变量分析显示,其与pCR呈正相关趋势(TIL每增加10%的校正比值比为1.15,95% CI 0.99–1.34;p=0.070),与IDFS也呈正相关趋势(每增加10%的校正风险比为0.71,95% CI 0.50–1.01;p=0.058)。未发现TIL与蒽环类治疗之间存在交互作用。结果提示,高TIL评分可能有助于识别预后良好的II–III期HER2阳性乳腺癌患者。

Tumor-infiltrating lymphocytes (TILs) have been associated with outcomes in HER2-positive breast cancer patients treated with neoadjuvant chemotherapy and trastuzumab.

However, it remains unclear if TILs could be a prognostic and/or predictive biomarker in the context of dual HER2-targeting treatment. In this study, we evaluated the association between TILs and pathological response (pCR) and invasive-disease free survival (IDFS) in 389 patients with stage II-III HER2 positive breast cancer who received neoadjuvant anthracycline-containing or anthracycline-free chemotherapy combined with trastuzumab and pertuzumab in the TRAIN-2 trial.

Although no significant association was seen between TILs and pCR, patients with TIL scores 60% demonstrated an excellent 3-year IDFS of 100% (95% CI 100-100), regardless of hormone receptor status, nodal stage and attainment of pCR.

Additionally, in patients with hormone receptor positive disease, TILs as a continuous variable showed a trend to a positive association with pCR (adjusted Odds Ratio per 10% increase in TILs 1. 15, 95% CI 0. 99-1. 34, p = 0. 070) and IDFS (adjusted Hazard Ratio per 10% increase in TILs 0. 71, 95% CI 0. 50-1. 01, p = 0. 058).

We found no interactions between TILs and anthracycline treatment.

Our results suggest that high TIL scores might be able to identify stage II-III HER2-positive breast cancer patients with a favorable prognosis.
