ABSTRACT

Objective To systematically analyze the relevant scientific literature on the effect of nasopharyngeal carcinoma radiotherapy on thy?roid function and to elucidate the current research status in this field. Methods We searched the relevant literature published over a recent de?cade using the PubMed database,and parameters such as the number of published articles and high?frequency keywords were counted. Cluster analysis of the high?frequency keywords was performed using SPSS software. Results We identified 2928 references and 11 high?frequency key?words. The clustering analysis results identified five main aspects. Conclusion In recently published articles on the effect of nasopharyngeal carci?noma radiotherapy on thyroid function,the high?frequency keywords were clustered mainly in the following five categories:nasopharyngeal carcino?ma radiotherapy,complications of nasopharyngeal neoplasms and etiology of hypothyroidism,radiation dose and side effects,effect of radiation ther?apy on thyroid functional,nasopharyngeal neoplasm pathology,and secondary carcinoma.
