Fig 2. Tumor growth curves obtained by measuring the volumes of the tumors in the study groups.

The volume ratio of the tumor was obtained from the initial volume (V₀) at the onset of the treatment (Day 0) to the following day. On the tumor growth curve, the mean volume ratio in each group on the follow-up dates was plotted. In the AART group, the tumor growth rate is much more suppressed than those in the other groups. RT, radiation therapy; AAT, antiangiogenic agent therapy; and AART, AAT plus RT.
