【摘要】 背景:研究发现许多恶性肿瘤患者血清中p53抗体水平异常增高,可能与p53基因突变、瘤体内P53蛋白异常积聚、肿瘤不良生物学行为有关。目前,国内对国人原发性肝癌的血清p53抗体阳性率及其与临床特征、预后的关系等研究尚少。 目的:分析原发性肝癌患者血清p53抗体与临床特征的关系并初步探讨肝癌介入治疗后的预后因素。 方法:用ELISA法定量分析肝癌首诊时的血清p53抗体,并与其性别、年龄、饮酒史、HbsAg、KPS评分、病理诊断、肿瘤分化程度、肝硬化、肿瘤生长方式、肿瘤分期、血管侵犯、有无肝外转移、Child分级、血清白蛋白、AFP、血清铁蛋白等资料进行单因素和多因素统计分析。用单因素和多因素logistic回归分析介入治疗后的预后因素。 结果:68例原发性肝癌血清p53抗体阳性率29.4%(20/68)。单因素分析显示,血清p53抗体阳性与肿瘤分化程度低、肝外转移、肿瘤分期晚、血管侵犯有关;多因素分析显示只有肝外转移与p53抗体阳性独立相关。血清p53抗体阳性者,介入治疗后疗效差于阴性患者。预后分析发现浸润生长、肿瘤分期晚(Ⅱb期)为独立的预后不良因素,而有饮酒史则预示预后可能较好。 结论:血清p53抗体阳性与原发性肝癌的不良生物学特征和预后不良有关。肝癌多因素预后分析初步显示浸润生长、肿瘤分期、饮酒是介入治疗后的预后因素。有必要扩大样本量进一步深入研究血清p53抗体在临床中的应用价值。
【Abstract】 Background: It has been found that the levels of serum anti-p53 antibodies elevated abnormally in patients with malignant tumors, and that such antibodies were associated with p53 gene mutations, abnormal accumulation of p53 protein in tumor tissue and bad biological action. So far, the prevalence of serum anti-p53 antibodies in primary hepatic cancer (PHC), clinical associations and value in prognosis are not well studied at home. Aim: To analyze the clinicopathological significance of serum anti-p53 antibodies in PHC and to preliminarily investigate prognostic factors after interventional treatment for PHC.Methods: The enzyme-linked immunosorbent assay (ELISA) was used to analyze serum anti-p53 antibodies in patients with PHC. The level of serum p53 antibodies and clinical data, i.e., age, sex, alcohol consumption, HbsAg, KPS performance, pathological diagnosis, differentiation, liver cirrhosis, pattern of growth, tumor stage, vascular invasion, remote metastasis, Child
