Recombinant Human Granulocyte Macrophage Colony Stimulating Factor(rhGM-CSF) Treating Oral Mucositis

A Open,Randomized Phase II Trial Comparing Local Use of rhGM-CSF and Compound Vitamin B12 Solution to Compound Vitamin B12 Solution Alone Treating Chemoradiotherapy-induced Oral Mucositis in Patients With Primary Nasopharyngeal Carcinoma

This is a open,randomized phase II trial comparing effectiveness and safety of local use of rhGM-CSF and Compound Vitamin B12 to Compound Vitamin B12 solution alone treating oral mucositis in primary nasopharyngeal cancer. The main end point is the incidence of grade II and less oral mucositis at the end of treatment.The hypothesis of the study is that the local use of rhGM-CSF and Compound Vitamin B12 can decrease the incidence of grade III and more oral mucositis at the end of treatment compared to local use of Compound Vitamin B12 alone.
