Analysis on Effects of Combined Radiotherapy with Thymic Peptide in Treating Moderate-advanced Nasopharyngeal Carcinoma

【Objective】To evaluate the effect of combined radiotherapy and thymic peptide on the survival rate of moderate-advanced nasopharyngeal carcinoma.【Methods】One hundred twenty four patients with stage Ⅲ and Ⅳ nasopharyngeal carcinoma were randomly divided into two groups,in which there were 60 cases in the combined therapy group and 64 cases in the radiotherapy alone group respectively.The 5-year survival rate,disease free survival rate,local control rate and distant metastasis rate in both groups were evaluated.【Results】 The 5-year survival rate,disease free survival rate,local control rate and distant metastasis rate of the combined therapy group were 61.6%、55%、66.7%、30% respectively,while the data of the control group were 40.6%、31.3%、54.7%、48.4%(P0.05).【Conclusion】The combined radiotherapy with thymic peptide can highly improve the survival rate of patients with nasopharyngeal carcinoma and lower its distant metastasis rate.
