Abstract
Background: The standard therapy in advanced hepatocellular carcinoma (HCC) is sorafenib (SOR),
which has the inconvenience of toxicity and discontinuation. Patient selection and the use of early
markers are critical for optimizing the potential benefit of SOR. Alpha-fetoprotein (AFP) has an es-
tablished role in HCC prognosis. The objective was to evaluate whether AFP variation during SOR
treatment reflects the lack of progression to SOR and can be used as a prognostic factor. Methods:
AFP levels were prospectively analyzed in 114 patients to determine whether the time to progres-
sion of AFP (TPA) at 3 months had a prognostic value for survival. Results: Between July 2007 and
October 2012, 114 patients were included (mean age 64 years, 97 male, 96 with cirrhosis). Etiology
was alcohol 47 (41%) and hepatitis C virus (HCV) 31 (27%). According to the Barcelona Clinic Liver
Cancer (BCLC) staging system: A (one case), B (24 cases) and C (89 cases). The Child-Pugh was Class
A in 89 cases. The general condition of the patient according to ECOG-PS was 0 in 73 cases. The me-
dian duration of treatment was 5 months (3.47 - 6.53, 95% CI). The median overall survival (OS)
was 9.23 months. The standard dose was maintained in 26 patients (22.8%). Sixty-seven percent of
patients experienced at least one adverse event grade 3-4. The time to progression of AFP lower or
higher than 3 months was an independent prognostic factor of OS (univariate and multivariate
analysis): 8.10 vs. 18.85 months, P < 0.001. Conclusion: HCC treated with SOR with TPA > 3 months
had longer OS, and TPA was an independent prognostic factor.
