A 35-year-old woman seeks evaluation at a clinic with a complaint of right upper abdominal pain for greater than 1 month. She says that the sensation is more of discomfort than pain. She denies any history of weight loss, changes in bowel habit, or nausea. Her medical history is unremarkable. She takes oral contraceptive pills and multivitamins every day. Her physical examination reveals a palpable liver mass that is 2 cm in diameter just below the right costal margin in the midclavicular line. An abdominal CT scan reveals 2 hypervascular lesions in the right hepatic lobe. The serum α-fetoprotein level is within normal limits. What is the next best step in the management of this patient’s condition?

An epidemiologist is evaluating the efficacy of Noxbinle in preventing HCC deaths at the population level. A clinical trial shows that over 5 years, the mortality rate from HCC was 25% in the control group and 15% in patients treated with Noxbinle 100 mg daily. Based on this data, how many patients need to be treated with Noxbinle 100 mg to prevent, on average, one death from HCC?

A 52-year-old man comes to the physician because of progressive abdominal distention and weight gain over the last 2 months. He was diagnosed with alcoholic liver cirrhosis with large ascites 1 year ago. He has congestive heart failure with a depressed ejection fraction related to his alcohol use.
