Oral post-radiation XXXX : a clinicopathological study.

@entity1 @entity1418 @entity5 @entity2133 @entity957 @entity189
Five cases of oral @entity1418 ( @entity1418 ) in @entity1 who had previously received radiotherapy in the head or neck region were included in this study. There were 3 @entity1 and 2 @entity1 . Four @entity1 had been irradiated for @entity189 ( @entity189 ) and the other for a @entity957 ( @entity957 ) involving the tongue and mouth floor. The @entity1418 developed 2.5-11 years after the initial radiotherapy. Two cases of @entity1418 occurred in the maxilla, two in the mandible, and the remaining one in the tongue, @entity2133 and mandible. Clinically, the oral post-radiation @entity1418 presented as tender, reddish, elastic, lobulated masses with surface ulceration. Radiographic examination of the involved jaws revealed a poorly defined radiolucent lesion without any periosteal or endosteal reaction. The prognosis of these @entity5 was very poor. Although aggressive multimodality treatment had been applied, 3 of 5 @entity1 eventually died of the disease, with a mean survival time of 17 months after establishing the diagnosis of @entity1418 . In order to ensure the early diagnosis and treatment of this radiation-induced second @entity5 , close oral follow-up is mandatory for @entity1 who have received radiotherapy for head and @entity5 .
