To study the 2-year PFS (progression-free survival) of patients with stage III nasopharyngeal carcinoma of pretreatment EBV DNA<4000 copy/ml treated with induction chemotherapy followed by two different doses of intensity-modulated radiation therapy and cisplatin.
To explore the 2 year PFS of patients with stage III nasopharyngeal carcinoma of pretreatment EBV DNA<4000 copy/ml treated with induction chemotherapy followed by reduced-dose radiation and cisplatin. The enrolled patients will receive 2 cycles of TPF regimen induction chemotherapy, if radiographic CR/PR and EBV DNA=0 after induction chemotherapy, the patients will be delivered by 60 Gy IMRT combined with 3 cycles of cisplatin concurrent chemotherapy. If radiographic SD/PD or EBV DNA>0 after induction chemotherapy, the patients will receive a total of 70 Gy IMRT combined with 3 cycles of cisplatin concurrent chemotherapy.
The included patients will be treated with 2 cycles of TPF regimen induction chemotherapy and 60Gy IMRT combined with cisplatin concurrent chemotherapy. The TPF regimen is consist of paclitaxel liposome 135mg/m2 d1, cisplatin 25mg/m2d1-d3 and 5-Fu 3750mg/m2 civ120h, with a total of two cycles. Concurrent cisplatin chemotherapy is delivered with dose of 100mg/m2, a total of three cycles. The third cycle of cisplatin concurrent chemotherapy is allowed to be delivered within one week after IMRT finished.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Reduced dose group | Experimental | After 2 cycles of induction chemotherapy with Paclitaxel Liposome, Cisplatin and 5-Fluorouracil, patients undergo low-dose intensity-modulated radiotherapy (IMRT) 5 days per week for approximately 6 weeks (30 fractions). Patients also receive cisplatin once per three week for 3 cycles. |
|
| Standard dose group | Experimental | After 2 cycles of induction chemotherapy with Paclitaxel Liposome,Cisplatin and 5-Fluorouracil, patients undergo standard-dose intensity-modulated radiotherapy (IMRT) 5 days per week for approximately 6 weeks (33 fractions). Patients also receive cisplatin once per three week for 3 cycles. |

| Overall response rate | Tumour response rate was classified according to RECIST, version 1.1 | 2 years |
| Incidence of acute toxicity | Numbers of patients of treatment-related adverse events as assessed by CTCAE v4.0. | 2 years |
| Incidence of late toxicity | Numbers of patients of late radiation toxicities were assessed using the Radiation Therapy Oncology Group and European Organization for Research and Treatment of Cancer late radiation morbidity scoring scheme. | 2 years |
| Change of ADC( apparent diffusion coefficient ) value of DWI(Diffusion-Weighted MRI) of patients predictive of failure | The ADC value of each patient of Diffusion-Weighted MRI at pretreatment and after induction chemotherapy was calculated were evaluated independently on a work station. | 2 years |
| Change of QoL | QoL scores were assessed for each scale by using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTCQLQ-C30) before induction chemotherapy, before radiotherapy, at the end of radiotherapy, at 3 months after radiotherapy, at 6 months after radiotherapy and 12 months after radiotherapy. | 1 years |
| Change of EORTC quality of life questionnaire(QLQ) Head and Neck score | QoL scores were assessed by using EORTC quality of life questionnaire(QLQ) Head and Neck. The QLQ-H&N35 is composed of seven multi-item symptom scales (pain, swallowing, sensation, speech, eating from a social,perspective, social interactions, and sexuality) and 11 single-item symptom scales (teeth, opening mouth,dry mouth, sticky saliva, coughing, felt ill, pain medication use, nutritional supplementation, feeding tube requirement, weight loss, and weight gain). All of the scales and items ranged in score from 0 to 100. A high score for a functional or global QoL scale represents a relatively high/healthy level of functional or global QoL, whereas a high score for a symptom scale or item represents a high number of symptoms or problems. | 1 years |
| Plasma EBV DNA copy number | Plasma EBV DNA copy number with either reduced or standard dose radiotherapy was assessed by qRT-PCR at pretreatment. The predictive value of plasma EBV DNA copy number was assessed by survival analysis. | 2 years |
