标题：The efficacy and toxicities of intensive induction chemotherapy followed by concurrent chemoradiotherapy in nasopharyngeal carcinoma patients with N3 disease
摘要：To assess the feasibility, efficacy and safety of 4 cycles of induction chemotherapy (ICT) followed by concurrent chemoradiotherapy (CRT) in nasopharyngeal carcinoma (NPC) patients with N3 disease. ICT consisting of paclitaxel (135 mg/m(2)) and nedaplatin (80 mg/m(2)) given every 3 weeks for 4 cycles followed by cisplatin-based CRT was planned. 22 patients completed 4 cycles of TP regimen ICT and the CRT according to the protocol. After 4 cycles of ICT, the ORR of the primary site was 100% (CR 22.7%, PR 77.3%), and that of the cervical lymph nodes was 95.5% (CR 27.3%, PR 68.2%). After the completion of CRT, the ORR of the primary site was 100% (CR 81.8%, PR 18.2%), and that of the cervical lymph nodes also reached 100% (CR 86.4%, PR 3.6%). The main hematological adverse events were grade 1 to 2 (G1/G2) neutropenia/anemia without febrile neutropenia. The most frequent toxicities during CRT were G1/G2 neutropenia, asthenia, oropharyngeal mucositis and skin injury. The median follow-up time was 46.5 (14 to 75) months. The 3-year PFS, DMFS, LRFS and OS were 81.8%, 81.8%, 100%, and 90.9%, respectively. The results suggest that intensive ICT followed by CRT in NPC patients with N3 disease is effective and well tolerated.
