†HR, Hazard ratios calculated using the unadjusted Cox proportional hazards model; *CI, confidence interval; ‡P-values were calculated by the unadjusted log-rank test. RT, Radiotherapy; OS, Overall survival; FFS, Failure-free survival; DMFS, Distant metastasis-free survival; LRFS, Local relapse-free survival; CRPT, Complete response of primary tumor.
