肿瘤相关抗原及抗体在肝癌诊断中的研究进展

Research progress in tumor- associated antigen antibodies for diagnosis of liver cancer

肝癌是全世界最常见的恶性肿瘤之一,虽然其治疗手段不断进步,但病死率仍居高不下。早期诊断可提高患者的生存时间,因此,亟须探索新的生物标志物以便及时诊断肝癌。当前研究的热点集中于肿瘤相关抗原(TAA)及对应的自身抗体来作为肿瘤血清学生物学标志,介绍了自身抗体的产生过程以及当前在肝癌组织中所发现的TAA组和抗-TAAs。此外,指出了这些新发现的自身抗体具有较高敏感性和特异性,将有助于肝癌的早期诊断。

Liver cancer is one of the most common malignant tumors in the world.The mortality of patients with liver cancer remains high e-ven with increasing progress in therapies.Early diagnosis is helpful for prolonging the survival of patients,so new biomarkers need to be ex-plored for timely diagnosis and treatment of liver cancer.The present research focuses on tumor-associated antigens （TAAs）and their cor-responding autoantibodies as serological biomarkers of liver cancer.The production of autoantibodies and the TAAs and anti-TAAs currently found in the liver cancer tissue are summarized.In addition,it is pointed out that these newly found autoantibodies have relatively high sen-sitivity and specificity for the early diagnosis of liver cancer.
