用电镜观察大肠癌80例,发现癌细胞间有淋巴细胞浸润者40例(50％),其中有淋巴细胞邻接癌细胞破坏(溶癌现象)者10例(25％)。淋巴细胞对癌细胞除了溶解破坏外,还可能阻挡癌细胞的活动,减弱其浸润。大肠癌细胞间淋巴细胞溶癌现象较为明显,虽不及鼻咽癌,但比人体其他肿瘤明显。 Observed by electron microscopy 80 cases of colorectal cancer and found that there are 40 cases (50%) of lymphocytes infiltrating between cancer cells, of which 10 cases (25%) were adjacent lymphocyte destruction (cancer). Lymphocytes in addition to the destruction of cancer cells, but also may block cancer activity, reducing its infiltration. Colorectal cancer cells lymphatic cell carcinoma phenomenon is more obvious, although not as nasopharyngeal carcinoma, but significantly more than the other human tumors.
