Long-term survival of patients with unresectable hepatocellular carcinoma treated with transcatheter arterial chemoinfusion.

Background Transcatheter arterial chemoembolization (TACE) has become one of the most common treatments for unresectable hepatocellular carcinoma. Published studies of TACE report a 5–16% risk of serious complications. Compared with TACE, transcatheter arterial chemoinfusion (TACI) may have similar efficacy and fewer side effects. Aim To examine the clinical outcomes of TACI. Methods We performed a retrospective cohort study of 345 consecutive TACI cases in 165 patients performed at a single United States medical center between 1998 and 2002. Primary outcomes were tumour response and survival rates. Results Only seven patients were hospitalized for more than 24 h after the procedure, and only three patients had worsening of liver function within 30 days of TACI. Survival was significantly poorer for patients with tumour-node-metastasis (TNM) IV compared to those with TNM I–III and also for patients with Child’s class B/C vs. A. Following adjustment for age, gender, ethnicity and aetiology of liver diseases, independent predictors of poor survival were Child’s class B/C [Hazard Ratio (HR) = 1.69, P = 0.024] and TNM IV staging (HR = 1.63, P = 0.014). Conclusions TACI appears to be safe and effective for unresectable hepatocellular carcinoma with TNM stage I–III; randomized controlled trials are needed to compare TACI to TACE.
