Purpose : To investigate the effect of patient and tumor factors on the degree of tumor
necrosis and the effect of the degree of the tumor necrosis on the survival in patients
treated with curative resection following transcatheter arterial therapy.
Materials and Methods : 90 patients diagnosed as having hepatocellular carcinoma and
treated with curative resection following transcatheter arterial therapy at Yonsei Medical
Center between January 1986 and December 1995. The subjects were classified into four
groups: 100% necrosis group (Group ¥°, n=29), over 95% necrosis group (Group ¥±,
n=28), 50¡­95% necrosis group (Group ¥², n=13) and below 50% necrosis group (Group
IV, n=20). The factors which affect on the necrosis of the tumor were compared. The
overall and disease-free survival rates according to the degree of tumor necrosis were
illustrated.
Results : There was no statistical difference in the degree of the tumor necrosis
according to age, sex, HBsAg, ¥á-FP, liver cirrhosis, tumor size and morphological
classification. In the comparison between the preoperative transcatheter arterial therapies,
however, transcatheter arterial chemo-oily embolization (TACOE), which used the
injection of the mixture of 3¡­10 §¦ Lipiodol and 30¡­50 §· Adriamycin followed by
Gelfoam embolization, showed the higher number of 100% necrosis and over 95%
necrosis cases. The 1, 3 year overall survival rates were greater for Group ¥°, although
not statistically significant. The 1, 5 year disease-free survival rates were greater for
Group ¥°, although not statistically significant.
Conclusion : In the preoperative transcatheter arterial embolization, TACOE was most
effective to get total necrosis of tumor. However overall survival and disease free
survival were not affected by the amount of tumor necrosis.
