Optimal cumulative cisplatin dose in nasopharyngeal carcinoma patients based on plasma Epstein–Barr virus DNA level after induction chemotherapy

Figure 2. Kaplan–Meier PFS (A), OS (B), LRFS (C), and DMFS (D) curves for the subgroup of 174 NPC patients with detectable EBV DNA level after induction chemotherapy stratified by CCD < 160 mg/m2, and CCD ≥ 160 mg/m2. Abbreviations: PFS = progression-free survival; OS = overall survival; LRFS = local-regional relapse-free survival; DMFS = distant metastasis-free survival; NPC, nasopharyngeal carcinoma; CCD = cumulative cisplatin dose.
