Tumor growth patterns for the experimental groups. Presented as mean ± SEM (n = 8 - 10 per group). The control group was removed from the study at day 21 due to tumor diameters exceeding 20 mm (A). Tumor growth delays as mean number of days for tumors to reach a 3-fold increase in relative tumor volume for each of the treatment groups versus the control group, TGD
. *The RT group did not reach 3-fold increase in relative volume at day 29; thus the TGD
is more than 19 days (B).
