研究概要

TILs 上 PD-1 的表达与肿瘤细胞上 PD-L1 的表达,与结直肠腺癌中 TILs 的分级显著相关。

中文摘要

结直肠癌(CRC)是一种常见且死亡率较高的恶性肿瘤。TIL(肿瘤浸润淋巴细胞)在抗肿瘤免疫应答中发挥关键作用。程序性死亡蛋白1(PD-1)和程序性死亡配体1(PD-L1)是调节肿瘤微环境中T细胞的重要免疫检查点。本研究旨在评估结直肠腺癌中TIL上的PD-1表达、肿瘤内PD-L1表达与TIL分级之间的关系。

采用横断面研究设计,分析130份结直肠腺癌样本。通过免疫组织化学评估PD-1和PD-L1表达,并采用半定量评分系统。使用SPSS 27版分析数据,并以卡方检验探索相关性。

TIL上的PD-1表达与较高TIL分级显著相关(p<0.001),而肿瘤内PD-L1表达与TIL分级呈负相关(p<0.001)。

结直肠腺癌中TIL上的PD-1及肿瘤细胞上的PD-L1表达均与TIL分级显著相关。这一发现提示其有望成为预测PD-1/PD-L1阻断疗法疗效的生物标志物。仍需进一步研究以加强这些结果的证据。

A cross-sectional design was employed to analyze 130 colorectal adenocarcinoma samples. The expression of PD-1 and PD-L1 was assessed through immunohistochemistry. A semi-quantitative scoring system was applied. Statistical analysis with the chi-square test was performed to explore correlations, with the data analyzed in SPSS version 27.

PD-1 expression on TILs significantly correlated with a higher TIL grading ( p < 0.001), while PD-L1 expression in tumors showed an inverse correlation with TIL grading ( p < 0.001).

The expression of PD-1 on TILs and PD-L1 on tumor cells correlated significantly with the grading of TILs in colorectal adenocarcinoma. This finding shows potential as a predictive biomarker for PD-1/PD-L1 blockade therapy. Further studies are needed to strengthen these results.
