Abstract
It has been confirmed gradually that transcatheter arterial embolization is the most effective, conservative therapy for the treatment of unresectable hepatic cell carcinoma (hepatoma). Embolization or one shot therapy was carried out in a clinical trial involving 41 patients with unresectable hepatoma visiting our department. Embolization group (emboli G): 19 cases. 1 to 6 embolizations in each case. One shot group (one shot G): 22 cases. Medications: Mitomycin C 10–40 mg and others. Disappearance rate of icterus after treatment was 50% (emboli G) and 25% (one shot G). Decrease in size of hepatomegaly or tumor was seen in 84% (emboli G) and 32% (one shot G) which was statistically significant (< 1 %). Serum AFP titer after embolization decreased in all cases but in only 5 of 12 cases (ca 41 %) after one shot (< 1 %). Effective cases measured by Karnofsky’s method were 18 out of 19 cases (95%) in emboli G, but in one shot G only 10 out of 22 cases (ca 45%)(< 0.1%). Survival rate after each therapy was 67% (emboli G) and 38% (one shot G) after 6 months, and 59% (emboli G) and 19% (one shot G) at 1 year respectively. One study showed that transcatheter arterial embolization therapy was much more effective than one shot therapy.
