EB病毒(EBV)特异的核壳抗原IgA抗体(VcA/IgA)在鼻咽癌的早期诊断上的价值已早被公认,并广泛应用于临床,VcA/IgA抗体阳性滴度上升者,更是潜在的发生鼻咽癌的高危人群,以往对此尚无有效治疗方法,我们在对鼻咽癌患者天然杀伤(NK)细胞活性研究中,发现癌症患者的NK细胞活性明显低于正常人,NE细胞活性的变化与临床病情的稳定与复发密切有关,患者血清中α-干扰素浓度降
The value of Epstein-Barr virus (EBV) specific core-shell antigen IgA antibody (VcA / IgA) in the early diagnosis of nasopharyngeal carcinoma has long been recognized and widely used clinically, and the increase of VcA / IgA antibody positive titer is even more Potential nasopharyngeal cancer in high-risk groups, in the past there is no effective treatment for this, our natural killer (NK) cell activity in patients with nasopharyngeal carcinoma study found that cancer patients with NK cell activity was significantly lower than normal, NE Changes in cell activity and clinical disease is closely related to the stability and recurrence, serum α-interferon concentration decreased
