Abstract

IntroductionGastric cancer (GC) is a highly heterogeneous malignancy, necessitating novel therapeutic targets. B7-H3 and CD39, as immune checkpoints, are potential modulators of the tumor microenvironment and may influence the efficacy of immunotherapies.MethodsB7-H3, CD39, and CD8 expression was assessed via immunohistochemistry (IHC) in 268 GC tissues and 80 gastric precancerous lesions. The correlation between B7-H3 and CD39 expression was analyzed using Spearman's correlation. Multiplex immunohistochemistry (m-IHC) was employed to determine the co-localization of B7-H3 and CD39 in GC tissues. Kaplan-Meier survival analysis and Cox regression models were utilized to evaluate clinical outcomes in different patient subgroups.ResultsBoth B7-H3 and CD39 expression showed a stepwise increase during gastric carcinogenesis including chronic superficial gastritis (CSG), chronic atrophic gastritis (CAG), low-grade intraepithelial neoplasia (LGIN), high-grade intraepithelial neoplasia (HGIN) to GC, with significantly higher expression levels in GC tissues compared to all precancerous lesions (P < .05). A significant positive correlation was observed between B7-H3 and CD39 expression (r = 0.2398, P < .001). Co-localization of B7-H3 and CD39 was detected within tumor nests and peritumoral regions and was significantly correlated with tumor volume (P = .017), tumor stage (P = .001), tumor depth (P = .002), lymph node metastasis (P = .005), lymph node involvement (P = .004) and distant metastasis (P = .028). Kaplan-Meier analysis revealed that patients with co-localized B7-H3 and CD39 expression exhibited significantly poorer prognosis (P = .0055). Cox regression analysis confirmed that this co-localization was a significant predictor of survival (P = .007) and an independent prognostic factor in multivariate analysis (P = .027).ConclusionThe co-localized expression of B7-H3 and CD39 in GC patients is strongly associated with poor prognosis. This dual-target expression pattern provides novel insights and a theoretical foundation for the development of dual-target immune checkpoint inhibitors as potential therapeutic strategies.

B7-H3和CD39在胃癌中的共定位:一种潜在的预后生物标志物和潜在的免疫治疗双靶点。
胃癌是一种高度异质性的恶性肿瘤,需要新的治疗靶点。B7-H3和CD39作为免疫检查点,是肿瘤微环境的潜在调节剂,可能影响免疫治疗的效果。方法采用免疫组化(IHC)方法检测268例胃癌组织和80例胃癌前病变组织中sb7 - h3、CD39、CD8的表达。采用Spearman相关法分析B7-H3与CD39表达的相关性。采用多重免疫组化(m-IHC)检测B7-H3和CD39在GC组织中的共定位。采用Kaplan-Meier生存分析和Cox回归模型评价不同患者亚组的临床结果。结果B7-H3和CD39的表达在慢性浅表性胃炎(CSG)、慢性萎缩性胃炎(CAG)、低级别上皮内瘤变(LGIN)、高级别上皮内瘤变(HGIN)至胃癌的癌变过程中呈逐步升高趋势,其中胃癌组织中B7-H3和CD39的表达水平明显高于所有癌前病变(P P P =)。017),肿瘤分期(P =。001),肿瘤深度(P =。002),淋巴结转移(P =。005),淋巴结受累(P = 0.004)和远处转移(P = 0.028)。Kaplan-Meier分析显示,B7-H3和CD39共定位表达的患者预后明显较差(P = 0.0055)。Cox回归分析证实,这种共定位是生存的重要预测因子(P = .007),也是多因素分析的独立预后因素(P = .027)。结论GC患者中B7-H3和CD39的共定位表达与预后不良密切相关。这种双靶点表达模式为开发双靶点免疫检查点抑制剂作为潜在的治疗策略提供了新的见解和理论基础。
