Surgical treatment of 109 patients with symptomatic and asymptomatic hepatocellular carcinoma.

A total of 109 patients with histologically proved hepatocellular carcinoma (HCC) have undergone hepatic resection during the 56-month period from October 1978 to May 1983. There were two sources of patients: those with symptomatic HCC (n = 47) and those with asymptomatic HCC (n = 62). A family tendency of HCC was noted in 11% of the patients studied. The percent of positive hepatitis B surface antigen (HBsAg) was 87%, and the serum alpha-fetoprotein was less than 20 ng/ml in 30% in the group with symptoms. The operative mortality rate was 3% and the hospital mortality rate was also 3%. The postoperative course was complicated with pleural effusion in 10%, bile leakage in 4%, subphrenic abscess in 4%, and upper gastrointestinal bleeding caused by gastritis in 1% of the patients. The actual survival rate for the 103 cases was 84% for 350 days and 28% for 1400 days. However, in the group with asymptomatic HCC with an average tumor size of 3.35 +/- 1.49 cm in diameter, the rate was 92% for 350 days and 44% for 1400 days. In the group with symptomatic HCC with an average tumor size of 10.6 +/- 5.1 cm in diameter, the rate was 76% for 350 days and 8% for 1400 days. The survival rate of the group with asymptomatic HCC was far better than that of the group with symptoms (p less than 0.05). In analysis of factors that might affect the patient's survival, only second or third operations (p less than 0.05), typical gross findings of tumor appearance (p less than 0.05), and an adequate margin were closely related (p less than 0.001). Neither the tumor size, the status of accompanying liver cirrhosis, the tumor location, nor the patient's sex and age affected the patient's survival (all p greater than 0.05).
