鼻咽癌是我国南方数省常见的恶性肿瘤之一。在对鼻咽癌进行组织形态学研究的同时,如何建立早期诊断、疑诊病例鉴别、疗效指标和预后指标,是一项新的课题。近年来,国内外许多学者证实EB病毒与鼻咽癌的关系十分密切。Wara等发现鼻咽癌病人血清中IgA水平升高,并认为是EB病毒抗元的特异抗体。接着,Henle等首先报告EB病毒壳抗元(VCA)特异的IgA抗体是鼻咽癌的一个显著特点,并用间接免疫荧光法测定放疗前鼻咽癌
Nasopharyngeal carcinoma is one of the common malignant tumors in several southern provinces of China. While conducting histomorphological studies on nasopharyngeal carcinoma, it is a new topic how to establish early diagnosis, identification of suspected cases, efficacy indicators, and prognostic indicators. In recent years, many scholars at home and abroad have confirmed the close relationship between EB virus and nasopharyngeal carcinoma. Wara et al. found that serum IgA levels in patients with nasopharyngeal carcinoma were elevated and considered to be specific antibodies against EB virus. Next, Henle et al. first reported that EBV-specific IgA antibody is a significant feature of nasopharyngeal carcinoma, and indirect immunofluorescence was used to measure prenasal nasopharyngeal carcinoma.
