本文总结了500例大肠癌临床病理材料,五年存活率55.5％,十年存活率33.75％。着重分析了肿瘤大小、大体类型、组织学类型、浸润深度、淋巴结转移、淋巴结反应类型与予后的关系。瘤组织分化的好坏,对予后可能起着非常重要的作用;免疫形态学改变确能反映予后。滤泡增生和淋巴细胞增生型和癌周组织淋巴细胞浸润与予后也有一定的关系。 This article summarizes 500 cases of colorectal cancer clinical pathological material, the five-year survival rate of 55.5%, the survival rate of 33.75%. The relationship between tumor size, gross type, histological type, depth of invasion, lymph node metastasis, type of lymph node response, and postmortem analysis was emphatically analyzed. The differentiation of the tumor tissue may play a very important role after the diagnosis; the morphological changes of the immune system can reflect the prognosis. Follicular hyperplasia and lymphoproliferative and lymphoid infiltrate in the pericancerous tissue also have a certain relationship with post-inflation.
