ObjectivesTo evaluate long-term results of a phase II study of induction and adjuvant gemcitabine and cisplatin (GP) chemotherapy with intensity-modulated radiotherapy (IMRT) in locoregionally advanced nasopharyngeal carcinoma (NPC).Materials and methodsOne hundred and twelve patients (Stage III: 65, IVA-B: 47) with locoregionally advanced NPC were enrolled in this study. All patients received induction chemotherapy consisting of 1000 mg/m² gemcitabine on day 1 and 8, and cisplatin 25 mg/m² on day 1–3, every 3 weeks for 2 cycles. Adjuvant chemotherapy for 2 cycles of the same regime was given 28 days after the end of IMRT. The IMRT technique was utilized for all patients.ResultsIn total, 97.3% patients completed 2 cycles of induction chemotherapy. The overall response rate (RR) of cervical lymph nodes was 89.0%. Acute toxicities were mainly grade 1–2 myleosuppression and vomiting. And 83.9% patients completed 2 cycles of adjuvant chemotherapy. All patients finished IMRT with RR at the end of IMRT for nasopharynx, lymph nodes of neck and retropharyngeal area being 99.1%, 97.9% and 97.7%, respectively. The 5-year local control, regional control, distant metastasis-free and overall survival rates were 93.2%, 92.3%, 89.0% and 82.1%, respectively. The 5-year overall survival of stage III and IVA-B were 87.0%, and 75.5%, respectively. The incidence of grade 3–4 acute radiotherapy-related mucositis was 28.6%. Severe late toxicities were uncommon.ConclusionIMRT combined with GP for locoregionally advanced NPC is well tolerated, effective, and convenient, and warrants further studies.
