Task: Answer Verification
Input (English): Question: Is malnutrition a prognostic factor in patients with hepatocellular carcinoma ( HCC )?
Answer: A significant proportion of patients with HCC is malnourished or at risk for malnutrition. Screening questionnaires and BIA measurement are superior to pure anthropometric measurements to identify the condition that negatively influences survival. The phase angle derived from body impedance analysis is an independent prognostic factor in patients with HCC.
Output (English): yes
