Usually, liver CT is performed at 1 week, 1 month, 6 months, and every year until 5 years after surgery. Afterwards, liver CT is performed at 2-year intervals. Measurement of blood tumor markers [AFP and prothrombin induced by vitamin K absence-II] is performed every month for 6 months after discharge from the hospital and every 3 months thereafter. Additional liver CT, liver magnetic resonance imaging, or positron emission tomography-CT is performed when elevated tumor markers or suspicious lesions were noted. A new lesion with radiographic features compatible with HCC is defined as recurrence of HCC based on the reports of specialist in radiology.
