随着免疫学的发展,肿瘤免疫日益受到重视,研究表明,肿瘤的发生、发展和预后均与宿主免疫状态密切相关;在抗肿瘤的免疫效应中,细胞免疫起着重要的作用;一般认为,Ｔ淋巴细胞为抗癌免疫反应的核心细胞。现将Ｔ淋巴细胞在肿瘤免疫调节中的作用及进展综述如下。1　肿瘤患者外周血Ｔ With the development of immunology, tumor immunity has received increasing attention. Studies have shown that the occurrence, development and prognosis of tumors are closely related to the host immune status. In the anti-tumor immune effects, cellular immunity plays an important role; generally believed that T lymphocytes are the core cells of the anti-cancer immune response. The role and progress of T lymphocytes in tumor immunomodulation are summarized below. 1 cancer patients peripheral blood T
