Abstract
Excepting operation-related deaths, including deaths within 30 days after operation and hospital deaths, and absolute non-curative resection cases, 171 resected cases of Hepatocellular carcinoma (HCC) were classified into 3 groups in terms of Kobayashi's risk score, namely, group A (score 7.5 or above; 29 cases), group B (7.4-6.0; 94) and group C (5.9 or below; 48). Results were: 1) The number of cases with a score of 6.0 or above was 123 out of 171 cases (71.9%). 2) In comparison with the other 2 groups, both postoperative survival rate and non-recurrent rate were significantly poor in group A (p<0.05), and this reason might lie not only in the recurrence but also in possible multicentric cancer causing. 3) There were 4 factors involved in increasing the risk score from group B to group A, namely, HBs-Ag (+), alcholic history (+), familiar history of HCC (+) and AFP≥21 ng/ml. On the other hand, there were 2 factors involved in decreasing the risk score from group B to group C, namely, sex and age (p<0.01). 4) The mean size of tumors in group A was larger than that in group C. Tumors in stage I or II were lesser in group A than the other 2 groups (p<0.05), however, there was no significant difference among the 3 groups in 7 factors such as macroscopic type, fc, fc-inf, vp, im, Hr and tw.
