AFP and neoplasm: At the time of antibody injection, mean serum AFP concentration for control (75,258 ± 38,683 ng/mL), low-dose (66,434 ± 35,895 ng/ml), and high-dose (75,568 ± 45,467 ng/mL) groups was not statistically significantly different (p=0.98), indicating equivalent overall tumor burden between groups at the initiation of the therapy (Figure 3).
