Serum α-fetoprotein (AFP) testing is no longer recommended for hepatocellular carcinoma (HCC) screening or diagnosis.1 However, AFP remains a valuable tool to monitor treatment response in the 60% to 75% of patients with AFP-producing tumors,13 and as a prognostic marker for recurrence after a liver transplant (LT).46 Although low or decreasing AFP levels at the time of LT predict a lower risk of recurrence, studies have not distinguished HCCs with low AFP levels as a result of cancer treatment from HCCs that do not produce AFP. Thus, it is uncertain whether conventional predictors of recurrence of HCC after LT extend to the subgroup of non-AFP–producing tumors, or whether the lack of AFP production indicates a distinct cancer behavior and prognosis.
