Objective To investigate the related factors and preventive measures of nasopharyngeal massive hemorrhage in patients with nasopharyngeal carcinoma after radiotherapy. Methods Clinical data of 43 nasopharyngeal massive hemorrhage patients with nasopharyngeal carcinoma after radiotherapy were analyzed retrospectively. Results Thirty-nine cases(90.7 %) had abroad skull base invasion due to tumor, 36 cases (83.7%) received high dose of radiation, and 13 cases (30.2 %) were accompanied by diabetes. Conclusion Tumor location is the major factor for nasopharyngeal massive hemorrhage, while radiation dosage, fractionation patterns and diabetes are the secondary factors. The measures in cluding hyperfractionation, overall dose control and blood sugar regulation should be taken for the high risk patients. Prevention is more important than salvage.
