Official title

A Randomized, Open-Label, Non-Inferiority Phase III Multicenter Clinical Trial Comparing Reduced-Dose to Standard-Dose Prophylactic Irradiation for Low-Risk Clinical Target Volume (CTV) in the Treatment of Nasopharyngeal Carcinoma.

Overview

To evaluate the locoregional control, survival rate, toxicity, and quality of life in patients with nasopharyngeal carcinoma treated with reduced prophylactic irradiation doses to the Low-Risk Clinical Target Volume (CTV).

Detailed description

This phase 3, multicenter, non-inferiority, randomized controlled clinical trial recruits patients with newly diagnosed, untreated, non-distant metastatic, non-keratinizing nasopharyngeal carcinoma (NPC). The intervention involves comparing reduced-dose prophylactic irradiation to standard-dose prophylactic irradiation for the low-risk clinical target volume (CTV). The objective is to compare the locoregional control, survival rate, toxicity, and quality of life between the two groups.

Interventions

  • Radiation Radiation Therapy
    PTVnx：70Gy/33Fr；PTVnd：70Gy/33Fr；PTV1：60Gy/33Fr；PTV2：42Gy/26Fr.
  • Radiation Radiation Therapy
    PTVnx：70Gy/33Fr；PTVnd：70Gy/33Fr；PTV1：60Gy/33Fr；PTV2：54Gy/33Fr.

Primary outcome measures

  • Locoregional relapse-free survival [Time frame: 3 year]
Secondary outcome measures (6)
  • Overall survival [Time frame: 3 year]
  • Failure-free survival [Time frame: 3 year]
  • Distant metastasis-free survival [Time frame: 3 year]
  • Acute toxicities [Time frame: 3 months]
  • Late toxicities [Time frame: 3 year]
  • Patient's quality-of-life [Time frame: 1 year]

Eligibility criteria

Inclusion criteria

Newly diagnosed, untreated, non-distant metastatic, and non-keratinizing NPC; aged between 18 and 70 years; Eastern Cooperative Oncology Group performance score of 0-1; adequate hematologic function (neutrophil count ≥ 1.5 × 10\^9/L, platelet count ≥100×109/L, and hemoglobin≥ 90 g/L); adequate renal function (creatinine ≤ 1.5 upper limit of normal \[ULN\]) or calculated creatinine clearance (CrCl) ≥ 60 mL/min (Cockcroft-Gault formula); and adequate hepatic function (serum bilirubin ≤ 2.0×ULN, and alanine aminotransferase and aspartate aminotransferase ≤ 2.5×ULN).

Exclusion criteria

Previous chemotherapy treatment, surgery (except diagnostic) or radiotherapy to the neck or nasopharyngeal regions; previous malignancy (except for cured basal cell carcinoma or carcinoma in situ of the cervix); lactation or pregnancy; or severe coexisting illness.
