Twenty-one patients(male 18 cases,femal 3 cases)died of primary liver cancer after operation are reviewed.The liver tumors were located in the right lobe(13 cases),left lobe(3 cases),middle position of liver(4 cases)and hepatic hilum(1 cases).The average diameter of the tumors were 9.0cm.All the patients had suffered from liver cirrhosis and were operated on (most of them partial hepatectomy).The times of death were about 7 days,7-14 days later after operation.The data suggest that causes of death were different from the different stage after operation.The relations between partial hepatectomy and hepatic failure,and the liver cirrhosis and liver regeneration are discussed.
