Abstract:
Objective:In order to investigate the clinical features and influence factors for incidence in patients with radiation-induced external auditory canal carcinoma (RIEACC).
Methods:The nasopharyngeal carcinoma (NPC) 16 patients who were diagnosised RIEACC after radiotherapy in the Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University from January 1990 to December 2017 were retrospectively analysis. The influence factors analysis were used Logistic regression analysis.
Results:Univariate analysis showed that age, somking history, family history of cancer and NPC stage were the influencing factors. Multi-factor logistic regression analysis showed that age, family history of cancer and NPC stage were independent risk factors.
Conclusions:RIEACC is rare complication of NPC patients received radiotherapy, which is also a multifactorial outcome. Age, family history of cancer and NPC stage is preliminary the main influencing factor. Although RIEACC has a low incidence, its malignancy should be highly vigilant.
