To evaluate outcomes in patients with right atrial (RA) hepatocellular carcinoma extension treated with transarterial chemoembolization. Eight patients were retrospectively reviewed. Follow-up visits occurred at 4-6 weeks; transarterial chemoembolization was repeated if residual tumor persisted. After transarterial chemoembolization, RA tumor volume reduction was 86% ± 19; α-fetoprotein level showed a reduction of 95%. From RA tumor diagnosis, 3-, 6-, and 12-month overall survival was 100% ± 0, 100% ± 0, and 67% ± 29, respectively. In patients with hepatocellular carcinoma invading the right atrium, transarterial chemoembolization alone or in combination with systemic therapy yields an improved imaging response and may be associated with improved survival.
