The impact of tumor-infiltrating lymphocytes (TILs) and tumor-associated macrophages (TAMs) on the prognosis of biliary tract cancer (BTC) is not completely understood. Therefore, in our study, we investigated the effects of the various immune cells infiltration in tumor microenvironment (TME).
A total of 130 patients with BTC who underwent surgical treatment at our institution were enrolled in this study. We retrospectively evaluated TILs and TAMs with immunohistochemical staining.
With CD8-high, CD4-high, FOXP3-high, and CD68-low in TME as one factor, we calculated Immunoscore according to the number of factors. The high Immunoscore group showed significantly superior overall survival (OS) and recurrence-free survival (RFS) than the low Immunoscore group (median OS, 60.8 vs. 26.4 months, p = 0.001; median RFS not reached vs. 17.2 months, p < 0.001). Also, high Immunoscore was an independent good prognostic factor for OS and RFS (hazards ratio 2.05 and 2.41 and p = 0.01 and p = 0.001, respectively).
High Immunoscore group had significantly superior OS and RFS and was an independent good prognostic factor for OS and RFS.
肿瘤浸润淋巴细胞(TILs)和肿瘤相关巨噬细胞(TAMs)对胆道癌(BTC)预后的影响尚不完全清楚。因此,在本研究中,我们研究了肿瘤微环境(TME)中各种免疫细胞浸润的影响。
本研究共纳入在我院接受手术治疗的 130 例 BTC 患者。我们采用免疫组织化学染色法对 TILs 和 TAMs 进行了回顾性评估。
以 TME 中 CD8-high、CD4-high、FOXP3-high 和 CD68-low 为一个因素,根据因素数量计算免疫评分。高免疫评分组的总生存(OS)和无复发生存(RFS)明显优于低免疫评分组(中位 OS:60.8 与 26.4 个月,p = 0.001;中位 RFS 未达到与 17.2 个月,p < 0.001)。此外,高免疫评分是 OS 和 RFS 的独立预后良好因素(风险比 2.05 和 2.41,p = 0.01 和 p = 0.001)。
高免疫评分组的 OS 和 RFS 明显更好,是 OS 和 RFS 的独立预后良好因素。
