Tumor growth delays (TGD) and Enhancement <i>ratios</i> (ER).

Complete responses were defined as the complete disappearance of a measurable tumor mass at some point after initiating therapy and maintained for 4 months. Median survival (in days) corresponds to the time needed by the tumors to reach five times their initial volume. TGD corresponds to the difference (in days) between median survival in treated group and median survival in CTRL group. ER was defined as TGDGEF+RT / [TGDGEF + TGDRT]. aComparison vs CTRL, p<0.05; bComparison vs RT, p<0.05.
