Aim: To evaluate overall survival (OS) in unresectable American Joint Committee on Cancer (AJCC) stage I/II hepatocellular carcinoma (HCC) treated with drug-eluting-bead transarterial chemoembolization (DEB-TACE) versus best supportive care.
Materials & methods: OS in consecutive patients with AJCC stage I/II unresectable HCC diagnosed in 2005-2010 who underwent DEB-TACE and similar patients from SEER with no surgery/radiation recommended/performed was evaluated.
Results: Median OS from HCC diagnosis was 28.9 months (DEB-TACE) versus 10.0 months (SEER), p < 0.0001. Median OS was 36.3 months (DEB-TACE) versus 12.0 months (SEER) in AJCC I, and 27.9 months (DEB-TACE) versus 10.0 months (SEER) in AJCC II, p < 0.0001. Significant independent prognostic factors for OS were single primary tumor, no vascular invasion, normal α-fetoprotein and DEB-TACE.
Conclusion: DEB-TACE in patients with unresectable AJCC stage I/II HCC was a significant independent prognostic factor for greater OS in a population-based study.
