淋巴细胞的细胞毒作用是指肿瘤患者的淋巴细胞在体外对肿瘤靶细胞的杀伤作用,这种现象不论在动物实验肿瘤系统中或在人体肿瘤中已被很多学者证实。鉴于食管癌在我国某些地区的发病率很高,但食管癌患者在体外的细胞毒性测定,以及在体内是否产生免疫反应等,在国内外尚未见任何报道,故作如下实验。 Cytotoxicity of lymphocytes refers to the killing effect of lymphocytes of tumor patients on tumor target cells in vitro. This phenomenon has been confirmed by many scholars in animal experimental tumor systems or in human tumors. In view of the high incidence of esophageal cancer in some areas of China, there are no reports at home and abroad for the determination of cytotoxicity of esophageal cancer patients in vitro and whether there is an immune response in vivo.
