Summary

Radiotherapy is an important treatment for initial distant metastases nasopharyngeal carcinoma. Total dose and fraction size are important prognostic factors for survival, although to our knowledge the optimal model has not been well determined to date. The purpose of this clinical trial is to investigate the optimal radiation dose to investigate the feasibility of decreasing the total dose and increasing the fraction size with the objective of achieving a better balance between local control and severe late complications. for initial distant metastases nasopharyngeal carcinoma with definitive radiotherapy.

Detailed description

PRIMARY OBJECTIVES: I. To determine if hypofractionated with a smaller total dose radiation is not inferior to standard-dose radiation in progression-free survival for initial distant metastases nasopharyngeal carcinoma . SECONDARY OBJECTIVES: I. To evaluate if hypofractionated with a low total dose radiation is not inferior to standard-dose radiation in overall survival and locoregional failure-free survival for initial distant metastases nasopharyngeal carcinoma II. To evaluate if hypofractionated with a low total dose radiation with chemotherapy decrease treatment-related toxicities OUTLINE: Patients are randomized to one of the two treatment arms ARM 1: Patients receive hypofractionated with a low total dose radiation with induced chemotherapy and adjuvant chemotherapy.Hypofractionated dose IMRT: GTVnx 60Gy, GTVnd 60Gy, PTV1 50Gy and PTV2 45Gy in 25 fractions, 5 days/week. Induced chemotherapy: Paclitaxel 135mg/m2 D1+Cisplatin 75mg/m2 D1(or D1-3), 3-week chemotherapy for 3 cycles. After radiation, patients receive adjuvant chemotherapy Paclitaxel 135mg/m2 D1+Cisplatin 75mg/m2 D1(or D1-3), 3-week chemotherapy for 3 cycles. ARM 2: Patients receive standard-dose radiation with concurrent chemotherapy. Standard-dose IMRT: GTVnx 69.69Gy, GTVnd 60-68Gy, PTV1 59.4Gy and PTV2 54Gy in 33 fractions, 5 days/week. Induced chemotherapy: Paclitaxel 135mg/m2 D1+Cisplatin 75mg/m2 D1(or D1-3), 3-week chemotherapy for 3 cycles. After radiation, patients receive adjuvant chemotherapy Paclitaxel 135mg/m2 D1+Cisplatin 75mg/m2 D1(or D1-3), 3-week chemotherapy for 3 cycles. After completion of study therapy, patients are followed up every 3-4 months for 2 years, then every 6 months for 3 years.
