迄今,血清VCA-IgA抗体检测,已作为临床上鼻咽癌有效的辅诊方法之一。其阳性率达93％(Henle.1976)。本文着重报导在本院门诊随机收集的38例鼻咽其它病变(A组)。82例以颈块为主诉的颈部其它病变(B组)和80例鼻咽癌(C组)的血清VCA-IgA抗体检测结果,并比较该抗体检测对它们的诊断意义。认为VCA-IgA检测对鼻咽癌鉴别诊断有一定价值。 材料与方法 本实验采用上海生物制品研究所提供的鼻咽癌免疫酶诊断试剂盒,实验方法和步骤与刘育希报告同。本文以抗体滴度≥1:5为阳性阈值。
So far, serum VCA-IgA antibody detection has been used as one of the clinically effective methods of auxiliary diagnosis of nasopharyngeal carcinoma. The positive rate is 93% (Henle. 1976). This article focuses on 38 cases of other nasopharyngeal lesions (Group A) randomly collected in our hospital. The results of serum VCA-IgA antibody detection in 82 cases with other neck lesions (group B) and 80 cases of nasopharyngeal carcinoma (group C) using neck blocks as main complaints were compared, and the diagnostic significance of this antibody test was compared. It is considered that the detection of VCA-IgA has some value in the differential diagnosis of nasopharyngeal carcinoma. Materials and Methods In this experiment, the diagnostic kit for nasopharyngeal carcinoma immune enzyme provided by Shanghai Institute of Biological Products was used. The experimental methods and procedures were the same as those reported by Liu Yuxi. In this paper, the antibody titers ≥ 1:5 as a positive threshold.
