HCC 患者中 CD8 + CD39 + TSTs 密度高且表现出肿瘤反应性表型的患者生存期改善,提示 CD8/CD39 免疫组化可能作为个性化治疗策略的预后工具。
肿瘤抗原特异性CD8+CD39+T细胞(TSTs)是抗肿瘤适应性免疫的重要组成部分,在肿瘤微环境(TME)中可处于不同的分化阶段,从早期干性样状态到终末衰竭阶段。我们的目的是评估肝细胞癌(HCC)TME中TSTs的定量和定性特征,取决于它们是否表现出干性样或衰竭特征。
我们分析了100例接受根治性肝切除术的HCC患者。在组织芯片切片上应用多重免疫组化(CD8/CD39/TCF1、CD8/CD39/TOX),并使用数字成像评估肿瘤中心、肿瘤周边及邻近非肿瘤肝组织中的T细胞浸润。在H&E染色切片上评估三级淋巴结构(TLS)。
在HCC TME中,72%的CD8+ T细胞共表达CD39,而44%的CD8+CD39+ TSTs共表达TCF1(干性样),超过50%共表达TOX(耗竭型)。肿瘤周边高CD8+CD39+ T细胞密度与更长的总生存期相关(p = 0.016)。肿瘤中心和周边CD8+CD39-TCF1+ T细胞浸润增加与更差的预后相关(p = 0.009)。TLS的存在与高TST密度相关(p < 0.001)。
We analyzed 100 HCC patients undergoing curative hepatectomy. Multiplex immunohistochemistry (CD8/CD39/TCF1, CD8/CD39/TOX) was applied on tissue microarray sections with digital imaging used to evaluate T cell infiltration in tumour center, periphery and adjacent non-neoplastic liver. Tertiary lymphoid structures (TLS) were assessed on H&E-stained slides.
In HCC TME, 72% of CD8 + T cells co-express CD39, while 44% of CD8 + CD39 + TSTs co-express TCF1 (stem-like) and over 50% co-express TOX (exhausted). High CD8 + CD39 + T cell density in tumour periphery was linked to longer overall survival (p = 0.016). Increased CD8 + CD39 - TCF1 + T cell infiltration in tumour center and periphery correlated with worse prognosis (p = 0.009). TLS presence was associated with high TST density (p < 0.001).
Patients with HCC and high CD8 + CD39 + TSTs density exhibiting a tumour-reactive phenotype have improved survival, suggesting the potential role of CD8/CD39 immunohistochemistry as a prognostic tool for personalised therapeutic strategies.
