ABSTRACT

OBJECTIVE@#To investigate the cause of epistasis in patients irradiated for nasopharyngeal carcinoma.@*METHOD@#Seventy nasopharyngeal carcinoma cases with epistasis after radiotherapy were retrospectively analyzed.@*RESULT@#The causes of epistasis were local nasopharyngeal carcinoma recurrent 34.3% (24/70), pseudoaneurysm 14.3% (10/70) and nasopharyngeal crust 51.4% (36/70). Seven cases with local recurrent, 3 cases with pseudoaneurysm and 1 cases with nasopharyngeal crust and osteoradionecrosis died of intractable epistasis.@*CONCLUSION@#Epistasis in patients irradiated for nasopharyngeal carcinoma is dangerous complication, especially in cases with local recurrent and pseudoaneurysm. Nasopharyngeal crust must be treated actively.
