Abstract:
OBJECTIVETo investigate the incidence of radiation-induced maxillary malignancy after radiotherapy for head and neck cancer.
METHODSA total of 273 patients who suffered from osteoradionecrosis after radiotherapy for head and neck cancer were evaluated. Among them, 6 patients were presented with carcinoma and sarcoma arising from maxillary area after radiotherapy.
RESULTSRadiation-induced maxillary cancers happened at a rate of 2.2% in the patients with osteoradionecrosis. There were no statistically significant differences in age, sex and the time interval between the radiotherapy and the cancer occurrence.
CONCLUSIONSRadiation-induced malignancy after radiotherapy for head and neck cancer is mainly located in maxilla, presenting as squamous cell carcinoma or sarcoma of the maxillary sinus.
