摘要
目的:研究口腔鳞状细胞癌(Oral squamous cell carcinoma,OSCC)患者外周血中不同淋巴细胞免疫表型的分布特征,探讨其与癌变相关危险因素及肿瘤生物学行为之间的关系。方法:选取49例口腔鳞状细胞癌患者和15例正常成人的外周血,应用流式细胞术检测外周血中T、B淋巴细胞及其各免疫表型的分布特征,并对其与槟榔咀嚼、吸烟、饮酒等癌变危险因素及肿瘤TNM分期和淋巴结转移相关性进行分析。结果:OSCC患者外周血中CD8^+T细胞、效应记忆T细胞(CD4^+Teff、CD8^+Teff)、CD4^+PD1^+T、CD8^+PD1^+T、CD8^+PD1^+Teff、CD8^+Tim3+T、CD8^+Tim3^+Teff的表达均显著高于正常对照组,而CD4^+初始T细胞(Tn)、B细胞则显著降低,且CD4^+Tn/CD4^+Teff、CD8^+Tn/CD8^+Teff比值均明显下降(P<0.05);OSCC患者外周血中CD8^+T细胞、CD4^+Teff、CD8^+Teff细胞的增高与淋巴结转移及肿瘤分期显著相关,且伴淋巴结转移或中晚期患者外周血中CD4^+Tn细胞及CD4/CD8、CD4^+Tn/Teff的比例均显著降低;OSCC患者外周血中CD4^+Teff比例的降低和CD4^+Tn细胞比例的升高与槟榔咀嚼显著相关(P<0.05),而饮酒和吸烟与T、B细胞各免疫亚型的改变无显著相关。结论:本研究发现OSCC患者外周血中淋巴细胞各免疫表型发生了改变,且这种改变与槟榔咀嚼及肿瘤进展显著相关。
Objective：To investigate the distribution of immunophenotypes of peripheral blood lymphocytes in patients with oral squamous cell carcinoma（OSCC）and to explore its role in the tumor progression and its relationship with cancer-associated risk factors.Methods：Forty-nine patients with OSCC and 15normal adults were enrolled in this study.Peripheral T and B lymphocytes and their immunophenotype distributions were detected by flow cytometry.The relevance of this distribution was analyzed with cancer-associated risk factors,including betel-chewing,smoking,alcohol drinking,tumor TNM stage,and lymph node metastasis.Results：The frequency of CD8＋T cells,effector memory T cells（CD4＋Teff CD8＋Teff）,CD4＋PD1＋T,CD8＋PD1＋T,CD8＋PD1＋Teff,CD8＋Tim3＋T,and CD8＋Tim3＋Teff in OSCC was significantly higher than that of normal control group,whereas the CD4＋Naive T cells（Tn）and B cells were significantly decreased,and CD4＋Tn/CD4＋Teff and CD8＋Tn/CD8＋Teff ratios were significantly decreased.The decrease of CD4＋Teff frequency was significantly associated with betel nut chewing,but the expression of CD4＋Tn cells was significantly increased（P〈0.05）.The history of drinking and smoking did not show any significantly difference in T and B cell immune subtypes.Conclusion：In this study,there were significant changes in the immunophenotypes of peripheral blood lymphocytes in patients with OSCC.The changes were significantly associated with betel chewing and tumor progression.
