NCT04448522 · Status: RECRUITING · Phase: PHASE3 · Type: INTERVENTIONAL · Enrollment: 508

Last updated 2020-09-28

No results posted yet for this study

Summary

Through multicenter, open-label, randomised clinical trials, we intend to demonstrate that radiotherapy with reduced dose could significantly reduce the incidence of radiotherapy toxicities, improve the quality of life of patients while ensuring the tumor control rates for NPC patients staged as II-III who are sensitive to induction chemotherapy (imaging evaluation of CR/PR and EBV DNA copy number decreased to 0 copies/mL after induction chemotherapy)

Conditions

  • Nasopharyngeal Carcinoma
  • Radiotherapy
  • Chemotherapy

Interventions

RADIATION

reduced dosage IMRT

1. Gemcitabine plus cisplatin induction chemotherapy: gemcitabine is injected intravenously at the dose of 1000 mg/m2 on the 1st and 8th day (within 30 minutes) for 3 cycles; cisplatin is injected intravenously at the dose of 80 mg/m2 on the 1st day, for 3 cycles. 1 cycles per 3 weeks. 2. Concurrent cisplatin chemotherapy: cisplatin is given at a dose of 100 mg/m2 via a continuous intravenous infusion during radiotherapy and starts on the 1st day of radiotherapy for 2 cycles. 1 cycles per 3 weeks. 3. IMRT: PTVnx：63.6Gy/30Fr/2.12Gy; PTVnd：63.6Gy/30Fr/2.12Gy; PTV1：54Gy/30Fr/1.8Gy; PTV2：49.2Gy/30Fr/1.64Gy
