Abstract Background: Nasopharyngeal carcinoma (NPC) originates from the mucous epithelium of the nasopharynx. Although induction chemotherapy plus concurrent chemoradiotherapy is the major therapeutic protocol used for locally advanced NPC without metastasis, more researches are needed to evaluate the curative effects.Aims: We aim to identify the therapeutic effects and prognosis after induction chemotherapy plus concurrent chemoradiotherapy in the treatment of locally advancedNPC under the intensity modulated radiotherapy mode.Methods: The patients (N= 544) with locally advanced NPC (III and IVa) after intensity modulated radiotherapy with induction chemotherapy and concurrent chemoradiotherapy were included in this study. We analyzed the characteristics of patients including gender, age, smoking status, tumor-node staging system, clinical stage, pathological type, the therapy protocol of induction chemotherapy and concurrent chemoradiotherapy, and chemotherapy prescription.Results: We have found the 5-year survival rates of OS, PFS, LRRFS, and DMFS were 85.21%, 78.51%, 90.71%, and 85.21% in follow-up and these data indicated that our therapeutic procedure provided beneficial effects on survival rates. Following, the chemotherapy drug base on DOC provided more beneficial effect of survival rate compared with TXT but there was no significant difference between chemotherapy drug base on DDP and NDP treated with NPC patients. The therapeutic effects of induction chemotherapy revealed no difference between TPF and TP. In addition, there was also no significant change between concurrent chemotherapy with TP dual drugs or platinum single drug. Moreover, the survival rate showed no difference between platinum accumulation dose ofmore and less than 150mg/m2for concurrent chemotherapy.Conclusion: Our results indicate that induction chemotherapy plus concurrent chemoradiotherapy under intensity modulated radiotherapy which is the standard therapeutic method for locally advanced NPC provides beneficial therapeutic effects, and it is worthy of further study.

Abstract Aim: To evaluate the efficacy of concurrent chemotherapy and high-dose (≥55 Gy) intensity-modulated radiotherapy (CCIMRT) in comparison with chemotherapy alone and intensity-modulated radiotherapy (IMRT) alone for unresectable locally advanced or metastatic pancreatic cancer. Methods: Forty-six patients with pancreatic cancer undergoing CCIMRT (n = 17), chemotherapy alone (n = 16) or IMRT alone (n = 13) were analysed. Overall survival (OS), locoregional progression-free survival (LRPFS) and gastrointestinal toxicities were evaluated. The median radiation dose was 60 Gy (range, 55–60) delivered in a median of 25 fractions (range, 24–30). Gemcitabine (GEM) alone, GEM + S-1, S-1 alone, FOLFIRINOX and GEM + nab-paclitaxel were used in CCIMRT and chemo-monotherapy. Results: The 1-year OS rate was 69% in the CCIMRT group, 27% in the chemotherapy group and 38% in the IMRT group (p = 0·12). The 1-year LRPFS rate was 73, 0 and 40% in the 3 groups, respectively (p = 0·012). Acute Grade ≥ 2 gastrointestinal toxicity (nausea, diarrhea) was observed in 12% (2/17) in the CCIMRT group, 25% (4/16) in the chemotherapy group and 7·7% (1/13) in the IMRT group (p = 0·38). Late Grade 3 gastrointestinal bleeding was observed in 6·3% (1/16) in the chemotherapy group. Conclusion: High-dose CCIMRT yielded acceptable toxicity and favorable OS and LRPFS.
