The authors investigated the association between cellular phone use and epithelial parotid gland malignancy. The subjects were 136 cases who were treated for this condition at the authors? hospital from January 1993 to March 2010, and 2051 controls who did not have salivary gland tumours and were admitted to the oral and maxillofacial surgery department during the same period. Logistic analysis was used to examine the relationship between cellular phone use and risk of epithelial parotid gland malignancy and mucoepidermoid carcinoma. Overall, the frequency of cellular phone use was not significantly associated with epithelial parotid gland malignancy. Female gender, advanced age, married status, high income, and smoking were associated with an elevated risk of epithelial parotid gland malignancy, especially mucoepidermoid carcinoma. Residence in a rural area was associated with reduced risk of epithelial parotid gland malignancy. The results suggest a possible dose?response relationship of cellular phone use with epithelial parotid gland malignancy. The authors suggest that the association of cellular phone use and epithelial parotid gland malignancy and mucoepidermoid carcinoma requires further investigation with large prospective studies.
