TNM Stage IVa의 진행성 간암에서 간동맥내 항암제 주입약제에 따른 치료성적과 예후인자

Abstract

BACKGROUND/AIMS: The study proposed to evaluate the efficacy of anticancer drugs of intraarterial chemoinfusion and investigate prognostic factors influencing survival. METHODS: A total of 127 patients diagnosed as having advanced hepatocellular carcinoma(HCC) of same stage (TNM stage IVa) from 1996 to 1998 were examined. Two intraarterial infusion chemotherapeutic regimens were employed: Adriamycin(Group I) and Cisplatin(Group II). RESULTS: Overall survival was significantly diffrent(10.0 vs 5.7months) and favored Group I. By the univariate analysis, significant prognostic factors included: age, portal vein thrombosis(PVT), size(>5cm) and type of tumor, response rate (size & -fetoprotein) at 3 months after therapy, level of albumin, alkaline phosphatase, and total bilirubin. After repeated therapy, Group I showed better survival (14.0 vs 7.9 months), but there was no statistical difference in survival rate between two groups in the case of large size, PVT, and diffuse type. CONCLUSION: Group I showed better survival than Group II in advanced HCC of TNM stage IVa. But, considering prognostic factors, there was no significant difference in survival rate between two groups except small size or nodular type of HCC. TNM classification of stage IVa should be reconsidered to include prognostic factors influencing survival rate such as PVT, size and type of HCC.
