Downstaging Unresectable Hepatocellular Carcinoma to Resectable Disease With Combined Immunotherapy and Stereotactic Beamed Radiotherapy: a Pilot Study

Recruiting now · Not applicable

Conditions studied: HCC - Hepatocellular Carcinoma, Unresectable Hepatocellular Carcinoma

In brief

Hepatocellular carcinoma (HCC) is one of the commonest cancers worldwide and ranks the third on the incidence of cancer-related death. There are more than 500000 new cases diagnosed annually worldwide. The incidence and prevalence of HCC are on rising trend with the majority of the disease burden is in Asia where viral hepatitis B is endemic. Surgical resection, radiofrequency ablation (RFA) and liver transplantation (LT) represent the only chance of cure for HCC patients. Despite more aggressive surgical approach has been adopted in most Asian countries, yet curative intervention remains only amendable in 30% of patients. Most patients are diagnosed with intermediate or advanced stage diseases; the long-term cure rate is only 0-10%. Hence, every effort has been made in an attempt to convert inoperable HCC into operable disease (i.e. downstaging) in order to improve the chance of survival of these patients. The current study, to our knowledge, will be the first study in the field to deploy a novel treatment strategy to deploy both immunotherapy and stereotactic beamed radiotherapy to induce tumor shrinkage rendering it become operable cancer.
