Of these, the University of California San Francisco (UCSF) criteria (a single lesion of ≤6.5 cm or 2–3 lesions ≤4.5 cm with a total diameter ≤8 cm), the Up-to-seven criteria (the sum of the size of the largest tumor [in cm] and the number of tumors should not exceed 7), and the French AFP model (a score calculated based on a combination of AFP level, tumor size, and number which should not exceed 2) have been most widely accepted [2–4]. Here, AFP is linked to neoplasm.
