curves of overall survival (OS) (A) and progression-free survival (PFS) (B) according to α-fetoprotein (AFP) response among patients with stable disease at the first radiological response evaluation. Patients with an AFP response had significantly longer OS and PFS than patients without an AFP response (median 12.7 versus 5.8 months, log-rank test P=0.027 for OS and 9.1 versus 3.7 months, log-rank test P=0.019 for PFS).
Abbreviation: vs, versus.
