Table 2 The actuarial 5-year overall survival, disease-free survival, locoregional progression-free survival, local progression-free survival, regional progression-free survival and metastasis-free survival rates in the intensity-modulated radiotherapy-treated and helical tomotherapy-treated groups

From: Impact of postoperative daily image-guided intensity-modulated radiotherapy on overall and local progression-free survival in patients with oral cavity cancer

5-year DFS 39.3 % 73.8 % 0.40 to 0.74 0.146
5-year LRPFS 49.8 % 69.8 % 0.37 to 0.77 0.104
5-year LPFS 58.4 % 85.2 % 0.58 to 0.70 0.006
5-year RPFS 81.2 % 81.4 % 0.62 to 0.72 0.653
5-year MFS 82.6 % 80.1 % 0.62 to 0.72 0.892
