鼻咽癌与EB病毒的密切关系,十分引人注意。用血清学的方法,在鼻咽癌病人中可以测到EB病毒早期抗原(EA)、壳抗原(VCA)等多种抗体,且具有一定的特异性,对鼻咽癌的诊断有一定意义。但鼻咽癌患者的抗体水平实际上是不一致的,其中少数患者是阴性,部分是弱阳性,部分是强阳性,影响抗体水平的因素目前还不清楚。本文报告了194例鼻咽癌患者治疗前血清中EB病毒早期抗原的免疫球蛋白G(EA-IgG)滴度的研究,以便进一步了解其对诊断的意义,并从病理改变方面探讨影响抗体水平的一些因素。
The close relationship between nasopharyngeal carcinoma and Epstein-Barr virus is very noticeable. Using serological methods, many antibodies such as Epstein-Barr virus early antigen (EA) and shell antigen (VCA) can be detected in patients with nasopharyngeal carcinoma, and have certain specificity, which has certain significance for the diagnosis of nasopharyngeal carcinoma. However, the antibody levels of patients with nasopharyngeal carcinoma are actually inconsistent. Among them, a small number of patients are negative, some are weak positive, and some are strong positive. The factors affecting antibody levels are still unclear. This paper reports on the study of EB virus early antigen antigen-IgG (EA-IgG) titer in 194 patients with nasopharyngeal carcinoma before treatment in order to further understand its significance for diagnosis, and explore the impact of the pathological changes in antibody levels Some of the factors.
