A Prospective Randomized Trial of Capecitabine Treatment in Patients With HNSCC

A Prospective Randomized Controlled Clinical Trial of Capecitabine Treatment in Patients With Locally Advanced Squamous Cell Carcinoma of the Head and Neck After Radiotherapy: Phase II Study

This prospective randomized controlled clinical Trial will be performed in patients with locally advanced squamous cell carcinoma of the head and neck. The objectives of the trial are to compare the efficacy and safety of Capecitabine treatment with placebo as adjuvant therapy to patients who have received radiotherapy.

4. Age between 18 and 65 years old
5. Prior treatment with chemo-radiotherapy (CRT) based Platinum drugs.
6. Adequate marrow: WBC count ≥4000/μL, hemoglobin ≥90g/L and platelet count ≥100000/μL.
7. Normal liver function test: Alanine Aminotransferase (ALT), Aspartate Aminotransferase (AST) ≤ 1.5×upper limit of normal (ULN) concomitant with alkaline phosphatase (ALP) ≤ 2.5×ULN, and bilirubin ≤ 1.5ULN.
8. Adequate renal function: creatinine clearance ≥60 ml/min.
9. Patients must be informed of the investigational nature of this study and give written informed consent.

Exclusion Criteria:

1. Nasopharyngeal carcinoma and/or salivary gland carcinoma.
2. Any other malignancy (except for primaries, appropriately treated superficial basal cell skin cancer and surgically cured cervical cancer in situ)

6. Severe hematological abnormality and intolerance to chemotherapy
7. Evidence of significant medical illness that in the investigator's judgment will substantially increase the risk associated with the subject's participation in and completion of the study.
8. Pregnancy or breast feeding
