EB病毒与鼻咽癌关系十分密切,鼻咽癌病人血清中EB病毒VCA-IgA抗体水平明显升高,这种抗体滴度与病理学之间的关系作者曾作过报导。本文就检测VCA-IgA抗体的临床意义和应用价值进行分析。材料与方法本文收集疗前鼻咽癌261例,放疗后3年以上鼻咽癌34例,鼻咽部非癌疾患36例,头颈部其它原发性恶性肿瘤47例,颈部淋巴结转移癌27例,颈部淋巴结炎性疾患10例和正常成年人140例。以上共555例血清应用免疫酶标记抗体间接法检测EB病毒VCA—IgA抗体,滴度≥1:5为阳性阈值。同时,除正常人
The relationship between Epstein-Barr virus and nasopharyngeal carcinoma is very close. The serum level of Epstein-Barr virus (VCA-IgA) antibody in patients with nasopharyngeal carcinoma is significantly higher. The relationship between this antibody titer and pathology has been reported by the author. This article analyzes the clinical significance and application value of the detection of VCA-IgA antibodies. Materials and Methods In this study, 261 patients received pretreatment nasopharyngeal carcinoma, 34 patients with nasopharyngeal carcinoma more than 3 years after radiotherapy, 36 patients with non-cancer disorders of nasopharyngeal tissue, 47 other primary malignancies of the head and neck, and metastatic lymph nodes of the neck. In 27 cases, there were 10 cases of cervical lymphadenitis and 140 cases of normal adults. A total of 555 cases of serum anti-EBV antibodies were detected by indirect immuno-enzyme-labeled antibodies. The titer ≥1:5 was the positive threshold. At the same time, in addition to normal people
