我们观察了以扩大根治术的方法清除的直肠癌的原发灶及所属上方及侧方一二三站的全部淋巴结内的免疫反应与远期生存率之间的关系。结果表明:随癌周纤维反应的增强五年生存率增高;随癌周浸润的淋巴细胞反应的增强五年生存率增高,癌周引流淋巴结(一二三站)内的SH、GH及PH反应程度均与五年生存率有关,随反应强度的增加五年生存率增高。我们认为应把癌周及引流淋巴结内的免疫反应作为判定预后的重要指标,进行常规病理学检查。
We observed the relationship between the immune response and the long-term survival rate of the primary tumor of rectal cancer removed by extended radical mastectomy and all the lymph nodes within the upper and lateral stations of the 1-3 stations. The results showed that the five-year survival rate increased with the increase of the fibrinergic phase of the cancer; the five-year survival rate increased with the lymphocyte reaction infiltrating the cancer week, and the SH, GH, and PH responses in the draining lymph nodes (one or two stations) in the cancer week. The degree is related to the five-year survival rate, and the five-year survival rate increases as the response intensity increases. We believe that the pathological changes in the lymph nodes around the tumor should be used as an important index to determine prognosis.
