本文就358例口腔鳞癌的癌周组织的淋巴细胞、浆细胞反应及120例引流淋巴结的反应状态进行观察,并分析其与预后的关系。结果表明:癌周淋巴细胞、浆细胞浸润是宿主抗肿瘤的一种防御性反应,随反应强度的增加,患者五年生存率明显增高。区域淋巴结的反应状态及淋巴结内窦组织细胞增生情况也可做为判断预后的病理学指际。 In this paper, we observed the lymphocyte and plasma cell response in 120 cases of oral squamous cell carcinoma, and the reaction status of lymphatic drainage in 120 cases, and analyzed their relationship with prognosis. The results showed that lymphocytic infiltration and plasma cell infiltration were defensive responses of the host against tumors. With the increase of reaction intensity, the five-year survival rate of patients was significantly higher. Regional lymph node response status and lymph node sinus tissue cell proliferation can also be used as a pathological indication for prognosis.
