由于EB病毒和鼻咽癌密切相关,运用多项EB病毒免疫学指标(VCA—IgA,EA—IgA,EA—IgG,EBNA)对鼻咽癌进行研究,结果表明VCA—IgA,EA—IgA和EA—IgG对鼻咽癌均较特异,临床上可起到相互补充的作用,从而进一步提高鼻咽癌的诊断水平,减少假阳性;将VCA-IgA运用到高发危险区人群普查中,将有助于提高鼻咽癌早期发现率;合用抗朴体免疫酶法和细针穿刺法检查鼻咽癌颈转移癌细胞的EBNA,对于原发灶不明的颈块鉴别诊断和鼻咽原发灶隐蔽(To期)的鼻咽癌而又首先表现为颈转移者的诊断是有效的。
Because EB virus is closely related to nasopharyngeal carcinoma, a number of EB virus immunological markers (VCA-IgA, EA-IgA, EA-IgG, EBNA) were used to study NPC. The results showed that VCA-IgA, EA-IgA and EA-IgG is specific to nasopharyngeal carcinoma and can complement each other clinically to further improve the diagnostic level of nasopharyngeal carcinoma and reduce false positives. The use of VCA-IgA in high-risk population surveys will have Helps to improve the early detection rate of nasopharyngeal carcinoma; combined with anti-mycoplasma immunoenzymatic method and fine needle aspiration to examine the EBNA of metastatic carcinoma of neck of nasopharyngeal carcinoma for the differential diagnosis of the unidentifiable primary tumor and the concealment of nasopharyngeal primary lesions The (To) stage of nasopharyngeal carcinoma and first manifestation of cervical metastases is valid.
