Locoregional progression-free survival (yellow) and freedom from distant metastases (blue). The 5-year locoregional control estimate was 97% (95% CI = 88.7% – 99.2%). KM freedom from distant metastases was 84.6% at 5 years (95% CI = 72.9% – 91.5%). Below the figure is shown the patients at risk at different time points; LR indicates locoregional DM indicates distant metastases.
