肝细胞癌(HCC)是常见的恶性肿瘤之一,发病隐匿,常由于诊断晚导致预后差,早期诊断对HCC至关重要.目前,病理组织学检查仍是诊断HCC的金标准,但存在创伤性、风险大等缺点;在非创伤性检查中,血浆甲胎蛋白(AFP)水平和超声波检查是目前最常用的监测手段,而AFP存在敏感度和特异度较低的缺陷[1].有研究[2]结果表明,血清AFP水平超过500μg/L时与肿瘤大小存在相关性,但约
Hepatocellular carcinoma (HCC) is one of the common malignant neoplasms with occult onset, often with poor prognosis due to late diagnosis, and early diagnosis is critical for HCC. Currently, histopathological examination is still the gold standard for HCC diagnosis, but there is trauma Sexual, risk and other shortcomings; in non-invasive examination, plasma alpha-fetoprotein (AFP) levels and ultrasound examination is the most commonly used monitoring means, and AFP there is a low sensitivity and specificity defects [1]. The results of the study [2] showed that there was a correlation with tumor size when serum AFP levels exceeded 500 μg / L, but about
