Hepatocellular carcinoma (HCC) is the most common malignancy that develops in cirrhotic livers. Its clinical and epidemiological characteristics and mortality rates vary according to geographical region. The objective of this study was to evaluate the clinical profile, epidemiological characteristics, laboratory parameters, treatment and survival of patients with HCC.
Patients with HCC seen between 2000 and 2012 were studied. The Kaplan-Meier method was used for survival analysis according to variables in question.
The study included 247 patients with a mean age of 60 ± 10 years. There was a predominance of males (74%). The main etiologies of HCC were HCV infection (55%), excessive alcohol consumption (12%), and HBV infection (8%). Liver cirrhosis was present in 92% of cases. The mean tumor number and diameter were 2 and 5 cm, respectively. Patients meeting the Milan criteria corresponded to 43% of the sample. Liver transplantation was performed in 22.4% of patients of the Milan subset and in 10% of the whole sample. The overall mean survival was 60 months, with a 1-, 3- and 5-year survival probability of 74%, 40% and 29%, respectively. Lower survival was observed among patients with alcoholic etiology. Survival was higher among patients submitted to liver transplantation (P < 0.001), TACE (P < 0.001), or any kind of treatment (P < 0.001). However, no difference was found for surgical resection (P = 0.1) or sorafenib (P = 0.1).
Patients with HCC were mainly older men diagnosed at an advanced stage. Treatment was associated with better overall survival, but few patients survived to be treated.
肝细胞癌(HCC)是肝硬化肝脏中最常见的恶性肿瘤。其临床和流行病学特征以及死亡率因地理区域而异。本研究的目的是评估HCC患者的临床特征、流行病学特征、实验室参数、治疗及生存情况。
对2000年至2012年间就诊的HCC患者进行研究。根据相关变量,采用Kaplan-Meier方法进行生存分析。
该研究纳入了247例患者,平均年龄为60±10岁。男性占主导(74%)。HCC的主要病因是丙型肝炎病毒(HCV)感染(55%)、过度饮酒(12%)和乙型肝炎病毒(HBV)感染(8%)。92%的病例存在肝硬化。肿瘤的平均数量和直径分别为2个和5厘米。符合米兰标准的患者占样本的43%。米兰亚组中22.4%的患者以及整个样本中10%的患者接受了肝移植。总体平均生存期为60个月,1年、3年和5年的生存概率分别为74%、40%和29%。酒精性病因患者的生存期较低。接受肝移植(P<0.001)、经动脉化疗栓塞(TACE)(P<0.001)或任何一种治疗(P<0.001)的患者生存期较高。然而,手术切除(P = 0.1)或索拉非尼治疗(P = 0.1)未发现差异。
HCC患者主要是老年男性,诊断时已处于晚期。治疗与较好的总体生存相关,但很少有患者能存活到接受治疗。
