近年来免疫学的迅速发展,使人们对肿瘤与免疫的关系有了进一步认识。大量实验表明,肿瘤能被宿主免疫系统识别并产生一系列复杂的免疫反应。一、肿瘤与免疫目前对肿瘤与细胞免疫系统间关系的研究较多,与体液免疫机制关系的研究较少,但也值得重视。观察宫颈癌、膀胱癌、乳腺癌及头颈部癌患者局部引流淋巴结的反应情况表明,无论是淋巴结的T细胞区域(副皮 The rapid development of immunology in recent years has led to a better understanding of the relationship between cancer and immunity. Extensive experiments have shown that tumors can be recognized by the host immune system and produce a series of complex immune responses. I. Tumor and Immunity At present, there are many studies on the relationship between tumor and cellular immune system. There are few studies on the relationship between humoral immune system and tumor, but it is also worthy of attention. Observing the local drainage of lymph nodes in patients with cervical cancer, bladder cancer, breast cancer, and head and neck cancer shows that whether it is the T-cell region of lymph nodes (subcutaneous
