Kaplan–Meier OS, DSS, DMFS and LRRFS curves for the poor-prognosis group between CRT and RT alone for 60–64 years old (A), 65–70 years old (B) and ≥ 70 years old (C). Poor-prognosis grou P = intermediate-risk group + high-risk group (intermediate-risk group: plasma EBV DNA titer ≤ 4000 copies/mL & T3–4; high-risk group: plasma EBV DNA titer > 4000 copies/mL & any T). EBV = Epstein–Barr virus; ACE-27 = adult comorbidity evaluation 27; OS = overall survival; DSS = disease-specific survival; DMFS = distant metastasis-free survival; LRRFS = locoregional recurrence-free survival; CRT = chemoradiotherapy; RT = radiotherapy
