As diagnosis of hepatic tumors has recently advanced, small liver cancer less than 5cm in diameter have been often detected. Forty three cases of the small liver cell cancer resected in our department were investigated.
Eleven cases were less than 2cm (A group) and 32 cases (B group) were over 2cm below 5cm in diameter. The patients with those liver cancer were evaluated as 0 or 1 of performance status and Child’s class A or B except one patient.
Fibrous capsule was shown in 64% of A and 78% of B. Liver cirrhosis was accompanied in 100% of A and, 81.2% of B. No significant difference was found between A and B. Tumor invasion beyond the capsule was observed in 40.0% of B and 14.2% in A. The 2 years survival rates indicated better prognosis in patients with no capsular invasion in both the groups.
One of 11 in A was in stage II and one in stage III. Only half patients in B belonged to stage I.
In conclusion, small liver cancer is not always an early cancer, but has a favorable prognosis. A curative resection based on the biological characteristics of the tumor and the remaining liver function is a choice of the treatment.
