This study aimed to elucidate the optimal cumulative cisplatin dose (CCD) for concurrent chemoradiotherapy (CCRT) according to the post-induction chemotherapy (IC) plasma Epstein-Barr virus (EBV) DNA level.
EBV DNA was detected and undetected in 179 and 370 patients, respectively. Of the entire cohort, 73/549 (13.3%) patients received a total CCD ≥ 160 mg/m and 476/549 (86.7%) patients, <160 mg/m. CCD enhancement was not associated with a survival benefit in patients with undetected EBV DNA after IC. However, among patients with post-IC detectable EBV DNA, higher 3-year PFS and locoregional relapse-free survival (LRFS) rates were observed in those who received a CCD ≥ 160 mg/m. Multivariate analysis also showed CCD was an independent prognostic factor for PFS and LRFS in patients with post-IC detectable EBV DNA.
CCD enhancement was not associated with a survival benefit in patients with undetected EBV DNA after IC. However, among patients with post-IC detectable EBV DNA, those receiving ≥160 mg/m CCD showed significantly improved 3-year PFS and LRFS.
NPC patients (549) treated with IC and CCRT were included. Prognosis was assessed using a multivariate Cox proportional hazards model. Furthermore, grade 1-4 toxicities were compared between different CCD groups.
本研究旨在根据诱导化疗（IC）后血浆 Epstein-Barr 病毒（EBV）DNA 水平阐明同步放化疗（CCRT）的最佳累积顺铂剂量（CCD）。
分别在 179 例和 370 例患者中检测到和未检测到 EBV DNA。在整个队列中，73/549（13.3%）例患者接受的总 CCD≥160mg/m，476/549（86.7%）例患者接受的总 CCD<160mg/m。在 IC 后 EBV DNA 未检测到的患者中，CCD 增强与生存获益无关。然而，在 IC 后 EBV DNA 可检测的患者中，接受 CCD≥160mg/m 的患者的 3 年无进展生存（PFS）和局部区域无复发生存（LRFS）率更高。多变量分析还表明，在 IC 后 EBV DNA 可检测的患者中，CCD 是 PFS 和 LRFS 的独立预后因素。

纳入接受 IC 和 CCRT 治疗的 NPC 患者（549 例）。采用多变量 Cox 比例风险模型评估预后。此外，还比较了不同 CCD 组之间的 1-4 级毒性。
