AbstractAbstract PDF
The concept of oligometastasis is widely accepted for various types of solid tumors; accordingly, better outcomes can be anticipated with aggressive local interventions. The treatment of advanced hepatocellular carcinoma (HCC) with extrahepatic metastasis is systemic therapy. However, treatment responses to systemic therapy are poor. Recently, a small number of metastatic cancers (oligometastasis) have been controlled by local therapy rather than systemic therapy. Our study reports a case of a 66-year-old male patient with advanced HCC with lung metastasis, which was treated with local therapy. There were less than four metastases in the lungs, which were treated with wedge resection, radiofrequency, and radiation therapy. He repeatedly underwent local therapy for lung oligometastasis and locoregional therapy for intrahepatic HCC rather than systemic therapy; control by local therapy was possible as his liver function was preserved with Child-Turcotte-Pugh class A.

Background/Aim
s: To reduce the cancer burden, the Korean government initiated the National Cancer Control Plan including the National Liver Cancer Screening Program (NLCSP). Ultrasonography examinations and α-fetoprotein tests at six-month intervals are currently offered for high-risk individuals. High-risk individuals are identified by reviewing the National Health Insurance Service claims data for medical use for the past two years using International Classification of Diseases Codes for specific liver disease. We surveyed the attitudes and opinions towards the NLCSP to understand the issues surrounding the NLCSP in Korea.
Methods
Altogether, 90 Korean Liver Cancer Association members participated in online and offline surveys between November and December 2019.
Results
Approximately one-quarter (27%) of the survey participants rated the NLCSP as very contributing and about two-thirds (68%) as contributing to some extent toward reducing hepatocellular carcinoma (HCC)-related deaths in Korea. Most (87.8%) responded that the current process of identifying high-risk individuals needs improvement. Many (78.9%) were concerned that the current process identifies individuals who use medical services and paradoxically misses those who do not. When asked for the foremost priority for improvement, solving ‘duplication issues between the NLCSP and private clinic HCC screening practices’ was the most commonly selected choice (23.3%).
Conclusions
The survey participants positively rated the role of the NLCSP in reducing liver cancer deaths. However, many participants rated the NCLSP as needing improvement in all areas. This survey can be a relevant resource for future health policy decisions regarding the NLCSP in Korea.

AbstractAbstract PDF
Obesity is closely associated with hepatocellular carcinoma (HCC) as well as other malignancies. Obesity is an important risk factor for cancer development and overall mortality in HCC. Molecular mechanisms of hepatocarcinogenesis in obesity are adipose tissue remodeling, dysregulation of adipokines, increased reactive oxygen species, insulin resistance or hyperinsulinemia, alteration of gut microbiota, and dysregulation of microRNA. Obesity is the most common cause of non-alcoholic fatty liver disease (NAFLD) or non-alcoholic steatohepatitis (NASH). NAFLD or NASH leads to HCC as well as liver cirrhosis. Hepatitis C virus regulates lipid homeostasis in liver. Obesity and its’ related factors (metabolic syndrome and diabetes mellitus) are significantly related to the risk of HCC development in chronic hepatitis C. However, it is not clear whether obesity is a risk factor for HCC in chronic hepatitis B. The relationship between obesity and HCC seems to be different according to etiology of background liver disease. Further studies are needed to clarify the effect of obesity on HCC in different etiologies of chronic liver disease.
