Postoperative Concurrent Chemoradiotherapy in Treating Patients With High-Risk Salivary Gland Carcinomas

Postoperative Concurrent Chemoradiotherapy in Treating Patients With High-Risk Salivary Gland Carcinomas of Head and Neck, A Non-Randomized, Phase II Trial

This is a non-randomized, phase II, open label study of postoperative current chemoradiotherapy for high-risk malignant salivary gland tumors of head and neck.The primary purpose of this study is to evaluate the efficacy and safety of concurrent chemoradiotherapy in these patients.

3. Surgical resection with curative intent within 8 weeks prior to registration, with no evidence of gross tumor residual

4. No evidence of distant metastases

5. No synchronous or concurrent head and neck primary tumors

6. Karnofsky score over 60

   3. Hemoglobin >= 10 g/dl
   4. AST and ALT <= 2.5 times institutional upper limit of normal (ULN)
   5. Total bilirubin <= 1.5 times institutional ULN
   6. Creatinine clearance >= 50 ml/min
   7. Serum creatine <= 1 times ULN

8. Signed written informed consent
