Brief Summary

Toxic and side effects during and after chemoradiotherapy for nasopharyngeal carcinoma seriously affect patients' treatment compliance and long-term quality of life. Active and effective prediction, prevention and management of toxic and side effects is an important element to improve the prognosis of patients. Leucogen has the ability to promote the growth and maturation of granulocytes in the bone marrow and the proliferation of leukocytes, and is widely used in radiation therapy and chemotherapy-induced leukopenia in malignant carcinomas. In addition, leucogen may have potential anticancer synergistic effects. Therefore, based on the application prospect of leucogen in preventing myelosuppression during chemotherapy for solid tumors, the study was designed to investigate the efficacy and safety of leucogen versus placebo on leukocyte and platelet whole-course management assisted by platinum plus low-dose long-term continuous intravenous infused 5-fluorouracil chemotherapy in the treatment of stage IV, recurrent or metastatic nasopharyngeal carcinoma.
