鼻咽癌是一种严重危害我国南方数省人群的恶性肿瘤,有关鼻咽癌的病理、临床分型、鼻咽癌的病因发病等问题,均存在不同的甚至截然相反的看法。通常,鼻咽癌为分化较差的鳞状细胞癌,早期转移至局部淋巴结,在癌细胞内可以找到EB病毒的基因组,鼻咽癌病人血液中常可检出与EB病毒有关的各种抗体,有的抗体(VCA—IgA)甚至可作为早期发现鼻咽癌的辅助指标,有的抗体效价可能与病程和预后有关。在分化较高的鼻咽癌细胞内较难发现EB
Nasopharyngeal carcinoma is a kind of malignant tumor that seriously endanger the population of several provinces in the south of our country. There are different or even opposite views on the pathology and clinical classification of nasopharyngeal carcinoma and the etiology of nasopharyngeal carcinoma. In general, nasopharyngeal carcinoma is poorly differentiated squamous cell carcinoma, early metastasis to the local lymph nodes, EB virus genomes can be found in cancer cells, nasopharyngeal cancer patients often detect the EB virus-related antibodies in the blood, Some antibodies (VCA-IgA) can even be used as an early indicator of nasopharyngeal carcinoma, and some antibody titers may be related to the course of disease and prognosis. In differentiated nasopharyngeal carcinoma cells more difficult to find EB
