摘要
食管癌一直以来是我国最常见的肿瘤之一,而其诊断阶段是判定患者生存预后的关键。然而,大多数食管癌病例在晚期才被诊断出来,其治疗方案有限,生存率低。研究显示食管癌有许多相关的相关免疫因素,其中包括程序性死亡蛋白-1 (Programmed Death-1, PD-1)及其配体程序性蛋白死亡配体-1 (Programmed Death Ligand-1, PD-L1)呈现出显著的疾病相关性。此外,促进抗肿瘤T细胞功能的其他机制是T细胞表面表达的共刺激分子,如4-1BB、ICOS,它们可以诱导细胞因子的产生、抗凋亡分子的表达和免疫反应增强。本文探讨PD-1、ICOS、4-1BB与食管癌的联系,提供了新的思路来寻找改进食管癌的诊断和预后的生物标志物。
Esophageal cancer has always been one of the most common tumors in China, and its diagnostic stage is the key to determining the survival prognosis of patients. However, most cases of esophage-al cancer are only diagnosed in the late stage, with limited treatment options and low survival rates. Studies have shown that esophageal cancer is associated with many immune factors, including Pro-grammed Death Protein-1 (PD-1) and its ligand Programmed Death Ligand-1 (PD-L1), which exhibit significant disease associations. In addition, other mechanisms that promote anti-tumor T cell func-tion are costimulatory molecules expressed on T cell surfaces, such as 4-1BB and ICOS, which can induce cytokine production, expression of anti-apoptotic molecules, and enhanced immune re-sponse. This article explores the relationship between PD-1, ICOS, 4-1BB and esophageal cancer, providing new ideas for finding biomarkers to improve the diagnosis and prognosis of esophageal cancer.
