现已知道,恶性肿瘤与免疫系统是有着重要关系。患病时在体液免疫方面,可对免疫球蛋白(简称Ig)之一种或几种发生影响,表现在血液中免疫球蛋白一种或几种含量上升。为探索恶性肿瘤患者的血液Ig水平关系,我们对41例肺癌和13例鼻咽癌患者的血清IgG、血清IgA、血清IgM进行了定量测定,以求了解肺癌、鼻咽癌和Ig之关系,希望对恶性肿瘤的防治有所帮助。 It is now known that malignant tumors have an important relationship with the immune system. In the aspect of humoral immunity during illness, one or more of immunoglobulins (abbreviated as Ig) may be affected, and one or more levels of immunoglobulin in the blood may increase. To explore the relationship of blood Ig levels in patients with malignant tumors, we quantitatively measured serum IgG, serum IgA, and serum IgM in 41 patients with lung cancer and 13 patients with nasopharyngeal carcinoma, in order to understand the relationship between lung cancer, nasopharyngeal carcinoma, and Ig. I hope to help prevent and treat malignant tumors.
