RESUMEN
OBJECTIVE: To evaluate the therapeutic efficacy of intensity-modulated radiation therapy(IMRT) combined with Delisheng injection for treatment of nasopharyngeal carcinoma (NPC). METHODS: Sixty-six patients with pathologically confirmed NPC (stage II and III) were randomized into therapeutic group and control group. Patients in the therapeutic group were treated with Delisheng injection in addition to IMRT and those in the control group with IMRT alone. RESULTS: No significant difference in the response rate occurred between the two groups. The incidence of adverse effects was significantly lower in the therapeutic group than in the control group, and the humoral immunity was improved in the former. CONCLUSION: Delisheng injection can decrease the side effects of IMRT and improve humoral immunity in NPC patients.
