ABSTRACT
A total of 154 sera from patients with nasopharyngeal carcinoma(NPC), patients with other head and neck tumors(OHNT) and healthy individuals (HI) from Shaanxi province were tested for IgA antibody to EB viral capsid antigen (VCA-IgA) by immunoenzyrnie method. 75.93% of 54 pretreated NPC patients had VCA-IgA antibody with a GMT of 1 38. 00,whereas less than 12. 00%of 50 OHNT and 50 HI with a GMT of 1 2. 5 ~ 1 3. 35.The results showed that the detection of VCA-IgA was of great value in diagnosis of NPC from low risk areas. The elevated level of VCA-IgA was seen in well-differentiated squamous cell carcinoma which gave a pattern similar to that noted in vacuolar nuclear cell carcinoma or less-differentiated carcinoma, but not in undifferentiated carcinoma. The VCA-IgA positive ratio in NPC patients below 30-year-old was similar to that in OHNT, however the GMT was elevated markedly. The results above showed that VCA-IgA antibody was of little value in diagnosis of NPC below 30-year-old and undifferentiated carcinoma.
