/ Aims : Cases of small hepatocellular carcinoma (HCC) have been increasing with the progress of diagnostic methods . In t his study the screening methods for early diagnos is of HCC were re-evaluated, and comparative ther apeutic analyses were perfomed. Methods : A total of 110 pat ients with small HCC (< 5 cm and < 4 nodules ) were retrospectively analyzed. The patients were divided into four treatment groups ; unt reated group (No T x, n=12), transarterial-oily-chemoembolization group (TOCE, n=43), combined treatment group of percutaneous ethanol injection and TOCE (CEI, n=22), OP group ( OP, n=33). Results : Small HCC occupied 22.6% of t ot al HCC cases . Only one thir d of small HCC cases were detected during the regular screening. In this group, Alpha- fet oprotein as say pr ovided a diagnostic clue in 50% of cases, ultras onography in 71%, and the combination of both in 88%. Five year s ur vival rat e and 5- year non- recurrence rate in small HCC was 29% and 37% respectively. Comparative ther apeutic analys es showed t hat CEI and OP gave a bet t er s ur vival t han T OCE in Child gr ade A. CEI prolonged survival in Child grade B wher eas TOCE did not . Only TOCE was tried and did not improve the survival in Child grade C. Conclus i on : 1) A more strict screening is needed in high risk group of HCC. 2) As a first line of treatment in small HCC, OP or CEI can be selected in Child grade A, and CEI in Child grade B. In Child grade C, a less invasive treatment (PEIT , microwave coagulat ion therapy) should be investigated. (Korean J Hepatol 1998;4:365 380)
