Non-surgical Treatment Options in Managing Recurrent Hepatocellular Carcinoma

Abstract

Despite advances in current treatment options, Hepatocellular Carcinoma (HCC) recurrence still presents as a significant clinical challenge. After initial treatment, HCC recurrence occurs in a considerable portion of patients without an available standardized protocol for managing such an incident. Recurrence of advanced liver disease may make surgical treatment options impossible, in which case, locoregional therapy should be considered as an alternative. This review article discusses recurrent HCC after initial treatment and available non-surgical treatment options. Along with systemic therapy, liver-targeted therapies for recurrent HCC including, radiofrequency, microwave ablation, transarterial chemoembolization, and stereotactic body radiation therapy are promising options. Thermal ablation with radiofrequency or microwave ablation is a suitable treatment option for patients who experience smaller tumor recurrences but are not operable because of comorbidities, impaired liver functions, or tumor locality. Transarterial chemoembolization or radioembolization using Yttrium-90 can be used for patients with an incurable disease and have comparatively low adverse effects.
