In the United Kingdom, as long as the AFP value is ≤1000 ng/mL, HCC patients with ≤5 nodules that are ≤3 cm in diameter or a single tumor of >5 cm but ≤7 cm in diameter with no evidence of tumor progression over a 6-month period are allowed to register with the waiting list [103]. The gene discussed is AFP; the disease is neoplasm.
