原发性肝细胞癌(简称肝癌)是常见的恶性肿瘤之一.其发病隐蔽,增长迅速,根据Sheu对28例直径≤5cm的早期无症状肝癌患者用B超进行观察,发现肿瘤倍增时间为29～398天,平均136天;并认为1cm的肝癌长到3cm只需4.6月.可见其生长之快.大量资料表明,有症状肝癌患者予后明显较无症状者差;大肝癌明显较小肝癌差.Lee报道,无症状者生存率远较有症者高(P<0.05);有症状者1年死亡率为24%,而无症状仅8%.Nagao报道,肿瘤直径≤5cm的患者预后较>5cm者好.所以我们要力争早期诊断出小肝癌(直径<5cm)及微小肝癌(<2cm).尽早手术,提高术后生存率.要早期诊断尚存在不少困难.作到早期诊断肝癌应从以下几方面着手.【对肝癌高危人群的普查】对肝癌高发地区和高
Primary hepatocellular carcinoma (HCC) is one of the most common malignancies. Its incidence is subtle and increases rapidly. According to Sheu’s observation of 28 cases of early asymptomatic liver cancer patients with a diameter of ≤ 5cm, B-ultrasound was observed. The tumor doubling time was found to be 29 to 398 days, an average of 136 days; and that 1cm of liver cancer grows to 3cm only 4.6 months. Visible growth. A large number of data show that patients with symptomatic liver cancer were significantly worse after asymptomatic; large liver cancer was significantly smaller Hepatocellular carcinoma is poor. Lee reported that the survival rate of asymptomatic patients is far higher than that of patients with symptoms (P<0.05); the 1-year mortality rate of symptomatic patients is 24%, and there is only 8% of asymptomatic patients. Nagao reported that patients with tumor diameter ≤5cm The prognosis is better than 5cm. Therefore, we must strive to early diagnosis of small hepatocellular carcinoma (<5cm in diameter) and small hepatocellular carcinoma (<2cm). Early surgery, improve the survival rate after surgery. To early diagnosis there are still many difficulties. Diagnosis of liver cancer should proceed from the following aspects.
