PFS rates of target lesions according to the modality of radiotherapy. The IG-IMRT group had a significantly longer median progression-free survival time of target lesions (). The median progression-free survival in the IG-IMRT group and the 3D-CRT group was months and months, respectively. The 1- and 2-year progression-free rates were 68.5% and 20.3% in the IG-IMRT group and 41.4% and 16.9% in the 3D-CRT group, respectively.
