Recent clinical applications of external beam radiotherapy for hepatocellular carcinoma according to guidelines, major trials and meta ‐analyses

SummaryExternal beam radiotherapy (EBRT) for hepatocellular carcinoma (HCC) has not been widely used due to lack of high ‐level evidence, despite its potent local therapeutic effect. While clinical evidence has accumulated and meta‐analyses of observational studies have provided integrated information to help in clinical decision‐making, a recent randomized trial demonstrated the benefit of EBRT in cases of HCC with major vessel invasion. Based on these trends, the efficacy of EBRT has been better recognized, and EBRT has been more frequently recommended in several international treatment guidelines newly updated in 2018. This review examined the key issues of EBRT in the guidelines updated in 2018 as well as recently published noteworthy randomized trials and meta‐analyses. Ongoing trials to identify the trends and direction of future research on EBRT for HCC were also reviewed.

In this study, 639 patients received TACE plus RT for HCC with MVI as a first-line treatment between January 2010 and December 2015. RESULTS: Main/bilateral portal vein and/or inferior vena cava tumor thrombus was observed in 353 (55.2%) patients. The median radiation dose was 39 Gy (range 24-50) with a 2.5-Gy (2-5) median fraction size. The median overall survival was 10.7 months, with 1- and 2-year survival rates of 46.5% and 23.9%, respectively. In the multivariate analysis, Child-Pugh classification B, tumor size>10 cm, infiltrative/diffuse type, presence of extrahepatic metastasis, alpha-fetoprotein>1...

Objectives: Most localized hepatocellular carcinoma (HCC) patients are not surgically operable or transplantation candidates, increasing the role for nonsurgical therapies. Ablative external beam radiotherapy (XRT) and transarterial radioembolization (TARE) are emerging radiotherapeutic treatments for localized HCC. We sought to evaluate their utilization and efficacy in a large nationwide cohort. Materials and Methods: We conducted an observational study of 2685 patients from the National Cancer Database (NCDB) diagnosed with American Joint Committee on Cancer 7th edition clinical stage I to III HCC between 2004 and ...

Hepatocellular carcinoma (HCC) is the second most common cause of cancer death worldwide, with a majority of HCC patients not suitable for curative therapies. Approximately 70% of initially diagnosed patients cannot undergo surgical resection or transplantation candidates due to locally advanced disease, poor liver function/underlying cirrhosis, or additional comorbidities. Local therapeutic options for patients with unresectable HCC, not suitable for thermal ablation, include transarterial embolization (bland, chemoembolization, radioembolization) and/or external beam radiation therapy (EBRT). Regarding EBRT specifically,...

CONCLUSIONS: MSC-based NIS-mediated 131I therapy after EBRT treatment dramatically enhanced therapeutic efficacy when a TGFB1-inducible SMAD-responsive promoter was used to drive NIS expression in adoptively applied MSCs. The remarkable therapeutic effect seen is thought to be linked in large part to the enhanced TGFB1 produced in this context, which leads to a highly selective and focused amplification of MSC-based NIS expression within the tumor milieu.

ConclusionsVisible uptake of Gd-EOB-DTPA by the liver parenchyma was significantly associated with liver function parameters. EOB-MRI can be a valuable imaging biomarker for the assessment of liver parenchyma function outside of radiation area.
