Local progression-free survival (LPFS) according to each response criteria. Modified response evaluation criteria in solid tumors (mRECIST) was the most significant factor for LPFS, but diffusion-weighted (DW) RECIST displayed comparable results.

Receiver operating curve analysis for local progression (LP). Area under the curve value was highest in modified response evaluation criteria in solid tumors (mRECIST) but was also comparable in diffusion-weighted (DW) RECIST.
