چکیده انگلیسی
Radiation-induced sarcoma (RIS) or postirradiation sarcoma has been reported rarely as a long-term complication of radiation therapy (RT). We report 4 cases of oral sarcomas or sarcomatoid tumors with a rather short latency period after radiotherapy of the prior OSCC. Histopathological evaluation and immunohistochemical study were performed using a panel of markers including vimentin, cytokeratin, S-100, desmin, myoglobin, HHF-35, p53, and p16. All reported cases were positive for vimentin and negative for cytokeratin. Two cases were positive for myoglobin, desmin, or HHF-35, and were probably myogenic origin. One case was possibly a fibrosarcoma and the subclassification of the other one was not specified. Diverse expression of p53 and p16 was further observed in these 4 cases. Report of the complicated clinical processes and the analysis of genetic markers of these cases provide useful clinical and pathogenetic insights of mesenchymal malignancies associated with a status post OSCC radiation.
