Clinical Factors Associated with Recurrence of Nasopharyngeal Carcinoma

Background and Objectives：The objective of this study was to investigate clinical factors associated with re-currence of nasopharyngeal carcinoma(NPC). Materials and Methods：We performed a retrospective review of 112 diagnosed as nasopharyngeal carcinoma, treated concurrent chemo-radiotherapy(CCRT) and had complete response from March 1, 1995, to March 31, 2012. Results：Of the recurrent NPC patients, patients received 2nd line chemotherapy had more recurrence within 2 years(p=0.010). Especially, patients received 2nd line chemo-therapy longer than 4 months tend to have recurrence early(p=0.035). Other factors are not different between re-current and non-recurrent NPC patients. Conclusion：The presence and the duration of 2nd line chemotherapy are associated with early recurrence.
