Cell line and treatment | Median tumor wt [mg] on day 25 (p value)] | % T/C, day 25 | Median time for tumor wt to reach 1300 mg in days (p value) | T-C (days) | Td (days)* | Log10 cell kill total |

Estimated from log-linear plot of data in Table I;
PC3N-α6-RR + RT values calculated against PC3N-α6-RR values;
% T/C = (Median Tumor Weight of Treated/Median Tumor Weight of Control) × 100;
T-C is tumor growth delay based upon the median time in days required for the treatment group (T) and the untreated control group (c) tumor to reach 1300 mg;
Td = Tumor doubling in days from log-linear portion of the tumor growth curve for untreated tumors;
Log Cell Kill = T-C/(3.32 × Td).
