GP Vs PF As Induction Chemotherapy Combined with CCRT for Locoregionally Advanced Nasopharyngeal Carcinoma

GP Vs PF As Induction Chemotherapy Combined with CCRT for Locoregionally Advanced Nasopharyngeal Carcinoma：a Prospective,Parallel, Randomized, Open Labeled, Multicenter Phase III Clinical Trial

The purpose of this study is to compare the survival and toxicity of GP (gemcitabine and cisplatin) vs. PF (cisplatin and fluorouracil) as induction chemotherapy combined with concurrent chemoradiotherapy (CCRT) for locoregionally advanced nasopharyngeal carcinoma( NPC ) patients.

Patients presented with non-keratinizing NPC and stage T1-4N2-3/T4N0-1M0 are randomly assigned to receive GP (gemcitabine and cisplatin) or PF (cisplatin and fluorouracil) induction chemotherapy combined with concurrent chemoradiotherapy. Patients in both arms receive radical radiotherapy, and cisplatin (100mg/m²) every three weeks for two cycles during radiotherapy. Patients in the investigational arm receive gemcitabine (1000 mg/m² d1,8) and cisplatin (80mg/m² d1) every 3 weeks for three cycles. Patients in the control arm receive fluorouracil (800mg/m² d1-5) and cisplatin (80mg/m² d1) every 3 weeks for three cycles. Our primary endpoint is progress-free survival (PFS). Secondary end points include distant metastasis-free survival (DMFS), overall survival (OS), locoregional relapse-free survival (LRRFS), initial response rates after treatments, toxic effects and quality of life (QoL).

Inclusion Criteria:

• Patients with newly histologically confirmed non-keratinizing nasopharyngeal carcinoma, including WHO II or III
• Tumor staged as T1-4N2-3/T4N0-1M0（according to the 8th AJCC edition）
• Male and no pregnant female
• Age between 18-65
• Adequate marrow: leucocyte count ≥4000/μL, hemoglobin ≥90g/L and platelet count ≥100000/μL
• Normal liver function test: Alanine Aminotransferase (ALT)、Aspartate Aminotransferase (AST) <2.0×upper limit of normal (ULN)
• Adequate renal function: creatinine clearance ≥60 ml/min
• Satisfactory performance status: Karnofsky scale (KPS) ≥ 70
• Without radiotherapy or chemotherapy
• Patients must give signed informed consent

Exclusion Criteria:

• Evidence of relapse or distant metastasis
• History of prior malignancy or previous treatment for NPC
• Any severe intercurrent disease, which may bring unacceptable risk or affect the compliance of the trial, for example, unstable cardiac disease requiring treatment, renal disease, chronic hepatitis, diabetes with poor control (fasting plasma glucose >1.5×ULN), and emotional disturbance.
• Pregnancy or lactation
