Abstract

Background:

Transarterial chemoembolization (TACE) is widely used for unresectable hepatocellular carcinoma (HCC), but the long-term survival benefit remains unclear.

Methods:

Pretreatment variables were analysed for factors predictive of actual 5-year survival from a prospective database of patients with inoperable HCC treated by TACE between 1989 and 1996.

Results:

Complete 5-year follow-up (median 91 months) was obtained for 320 patients who underwent a median of 4 (range 1–41) TACEs. Median tumour size was 9 (range 1–28) cm. There were 25 5-year survivors (8 per cent), including eight with tumours larger than 10 cm in diameter and three with portal vein branch involvement. On univariate analysis, female gender (P = 0·037), absence of ascites (P = 0·028), platelet count below 150 ×109 per litre (P = 0·011), albumin concentration greater than 35 g/l (P = 0·04), α-fetoprotein level below 1000 ng/ml (P = 0·007), unilobar tumour (P = 0·027), fewer than three tumours (P = 0·015), absence of venous invasion (P = 0·011), and tumour diameter less than 8 cm (P = 0·021) were significant predictors of 5-year survival. Albumin concentration greater than 35 g/l (P = 0·011), unilobar tumour (P = 0·012) and α-fetoprotein level below 1000 ng/ml (P = 0·014) were independent prognostic factors on multivariate analysis.

Conclusion:

Five-year survival is possible with TACE for inoperable HCC, even in some patients with advanced tumours. Unilobar tumours, α-fetoprotein level below 1000 ng/ml and albumin concentration greater than 35 g/l were factors predictive of 5-year survival.
