Neoadjuvant chemotherapy followed by concurrent chemoradiotherapy versus concurrent chemoradiotherapy alone in nasopharyngeal carcinoma patients with cervical nodal necrosis

Abstract

The effectiveness of neoadjuvant chemotherapy (NACT) followed by concurrent chemoradiotherapy (CCRT) compared with CCRT alone in nasopharyngeal carcinoma (NPC) patients who presented with cervical nodal necrosis (CNN) is unknown. A total of 792 patients with stage T1-4N1-3M0 NPC and presented with CNN based on magnetic resonance imaging were retrospectively reviewed. Propensity score matching method was used to balance treatment arms for baseline characteristics. Eventually, 508 patients were propensity-matched on a 1:1 basis to create two groups (NACT + CCRT and CCRT groups). Survival rates were calculated by Kaplan-Meier method and differences were compared by using the log-rank test. The 5-year disease specific survival, disease-free survival and distant metastasis-free survival were significantly higher in NACT + CCRT group relative to the matched CCRT group (82.1% vs. 72.5%, P = 0.021; 70.3% vs. 54.1%, P < 0.001; 81.9% vs. 67.3%, P < 0.001, respectively). Although the rates of grade 3-4 leucopenia and mucositis were higher in NACT + CCRT group than CCRT group, compliance with the combined treatment was good and no significant difference was observed between two groups. NACT followed by CCRT was relatively safe and could achieve better survival than CCRT alone in NPC patients with CNN by reducing the risk of death, tumor progression and distant metastasis.
