Abstract

<abstract> <title>Abstract</title> <p> <italic>Conclusion:</italic> The prognosis and late adverse effects of radiotherapy (RT) in the patients with nasopharyngeal carcinoma (NPC) with or without dermatomyositis (DM) were similar, although the NPC patients with DM had higher Epstein-Barr virus (EBV) VCA-IgA titers and more severe acute side effects. Gender, TNM stage, and chemotherapy were independent prognostic factors of overall survival for NPC with DM. Glucocorticoid treatment did not affect the survival of NPC patients with DM. <italic>Objectives:</italic> We evaluated the clinical characteristics, prognosis, and differences in the toxicity of RT in patients with NPC with or without DM. <italic>Methods:</italic> A paired study of 172 NPC cases with DM (DM group) or without DM (control group) from Sun Yat-sen University Cancer Center was conducted. <italic>Results:</italic> The DM group had higher EBV VCA-IgA titers than the control group (<italic>p</italic> = 0.017) and more acute adverse effects of RT (<italic>p</italic> &lt; 0.001). No significant differences in the overall survival or late adverse effects were found between the two groups. Gender, TNM stage, and chemotherapy were independent prognostic factors for the overall survival in the DM group. No significant differences in the overall survival were found between the patients in the DM group who were taking glucocorticoids and those who were not.</p> </abstract>
