肿瘤免疫学研究证实 ,恶性肿瘤病人机体的免疫功能均有程度不同的降低 ,对肿瘤的发生、发展、转移、疗效及预后有直接影响[1] 。其中Ｔ淋巴细胞介导的细胞免疫是肿瘤免疫的主要方面 ,ＴＨ 与ＴＳ 细胞是肿瘤免疫调节的重要细胞[2 ] 。为探讨恶性肿瘤病人免疫功能的变化及抗肿瘤
Tumor immunology studies have confirmed that the immune function of malignant tumors in patients with varying degrees of reduced, on the tumor occurrence, development, metastasis, efficacy and prognosis have a direct impact [1]. Among them, T lymphocyte-mediated cellular immunity is the main aspect of tumor immunity. TH and TS cells are important cells in tumor immunoregulation [2]. To investigate the changes of immune function in patients with malignant tumors and anti-tumor
