OBJECTIVE: To study the changes of the clinical aspects of primary liver cancer (PLC) during the past 30 years. METHODS: The clinical data of 3,250 patients with PLC, from 10 regions of China were collected, analyzed, and compared with the clinical data of 3254 PLC cases 30 years before. RESULTS: The 3,250 patients were aged 1- 80, with an average age of 49.1 years, younger than those 30 years before (43.7 years). The male to female ratio was 2.3:1, lower than that 30 years before (7.7:1). 73.5% of them sought medical advice within 3 months after the onset in comparison of 63.8% 30 years before. Compared with those 30 years before the symptoms and signs were alleviated in general. The HBsAg positive rate was 81.0%, the HCV-Ag positive rate was 13.2%, and the alpha-fetoprotein positive rate was 75%. 1912 cases underwent pathological examination of which 91.8% were diagnosed as with hepatocellular carcinoma. The overall resection rate was 46,3%. Those of early, median, and late stages accounted for 29.9%, 51.5%, and 18.6% respectively in comparison with the rates of 0.4%, 47.0%, and 52.6% 30 years before. The one-year survival rate, three-year survival rate, and five-year survival rate were 66.1%, 39.7%, and 32.5% respectively for the whole group, 93.5%, 70.1%, and 59.1% for the early stage patients, and 65.3%, 30.5%, and 23.5% respectively for the median stage patients. The half-year survival rate and one-year survival rate of the late stage patients were 52.5% and 14.7% respectively. Compared with the data 30 years before a lower percentages of the patients died of hepatic coma, hemorrhage of upper digestive tract and hemorrhage due to rupture of tumor, and a higher percentage of then died of asthenia universalis and other causes. CONCLUSION: In comparison with the situation 30 years ago, PLC can be diagnosed earlier. More patients undergo resection. The prognosis of PLC has been improved greatly.
