Editorial note:


Immune checkpoint inhibitors revolutionize the field of immuno-oncology. They have demonstrated great potential in a wide range of adult cancers by reaching long-lasting objective responses and prolonging survival. Through completed and on-ongoing clinical trials, their indications continue to expand among different cancer types.

Introduction

Non-alcoholic fatty liver disease (NAFLD) is a serious global health problem and associated with over-nutrition and its related metabolic risk factors including central obesity, glucose intolerance, dyslipidaemia and hypertension. It is the most common metabolic liver disease worldwide and its prevalence in most Asian countries is similar to that in the States, Europe and Australia. About 10-45% of Asian population have NAFLD. With “westernized” sedentary lifestyle, the prevalence of NAFLD in general urban population in the mainland China is about 15%. NAFLD is even more prevalent in Hong Kong. Our recent study demonstrated...
