Figure 1

Local progression-free survival curves for patients with IFRT or ENI. The 1-, 2-, and 3-year local tumor progression-free survival rates in the IFRT arm were 78.1%, 72.6%, and 62.9% compared with 85.5%, 61.2%, and 56.1%, respectively, in the ENI arm. There was no statistically significant difference in local progression-free survival between the two arms ( ).
