[Evolution and prognosis in patients with primary liver cancer. I. The effect of individual factors on the survival of patients with primary liver cancer].

The data of the frequency, evolution and prognosis of 63 patients with primary liver carcinoma which had developed on the basis of liver cirrhosis are presented. An attempt is made to assess the importance of the etiologic factors, type of liver cirrhosis, macroscopic type of the tumor, histologic pattern of the cancer, sex and age for the evolution and prognosis of the disease. The patients with primary liver carcinoma without cirrhosis have a better prognosis. As high risk factors may be accepted: male sex, age over 50 years, toxic factors, hepatitis B virus infection and chronic alcoholism. The macroscopic type of the tumor also affects the prognosis. The histologic pattern of the cancer does not influence the survival of the patients with primary liver carcinoma.
