鼻咽癌是我省常见的恶性肿瘤之一,根据1978年全省肿瘤死亡回顾调查资料分析,鼻咽癌的死亡率为2.47/10万。而以往鼻咽癌的诊断一般依靠病理学的检查,但因鼻咽腔位置隐蔽,要判断其病变性质取活组织检验有时有一些困难,因此建立一种简易、快速、特异的血清学方法诊断鼻咽癌是有十分必要的。近年来根据国内外许多研究报告,证明 EB 病毒与鼻咽癌有密切关系,尤其是抗 EB 病毒壳抗原的免疫球蛋白 A 抗体(VCA—1gA)对鼻咽癌有较高的特异性。鼻咽癌患者血清中的 VCA—1gA 抗体阳性率达90%以上,其他恶性肿瘤患者和
Nasopharyngeal carcinoma (NPC) is one of the common malignancies in our province. According to a review of cancer deaths in the province in 1978, the mortality rate of nasopharyngeal carcinoma was 2.47/100,000. In the past, the diagnosis of nasopharyngeal carcinoma usually relied on pathological examination. However, due to the concealed location of the nasopharyngeal cavity, it is sometimes difficult to determine the nature of the disease by taking a biopsy test. Therefore, a simple, rapid, and specific diagnosis of serological methods is established. Nasopharyngeal cancer is very necessary. In recent years, according to many research reports at home and abroad, it is proved that EB virus is closely related to nasopharyngeal carcinoma, especially the immunoglobulin A antibody (VCA-1gA) against EB virus shell antigen has high specificity for nasopharyngeal carcinoma. The positive rate of VCA-1gA antibody in serum of patients with nasopharyngeal carcinoma was over 90%. Patients with other malignant tumors were
