[์˜๋ฌธ] There have been many reports on the etiological role of HPV in various oral diseases including carcinomas. Present study was performed to elucidate the distribution of HPV 16/18 in oral squamous cell carcinomas, leukoplakias and papillomas of Koreans.24 cases of squamous cell carcinomas,7 cases of leukoplakias and 6 cases of papillomas were reviewed through immunohistochemical staining using anti-HPV 16/18 E6 monoclonal antibody, Obtained results were as fellows : 1. Positive reactions were observed in 6 cases out of 24 squamous cell carcinomas. Among the 6 positive cases 3 cases showed positive reaction broth in the tumor cells and the adjacent epithelial cells, whereas the remaining 3 cases only in the adjacent epithelial cells. 2. 4 cases out of 7 leukoplakias reacted positively, all of which showed no dysplasia. 3. Positive stainings were observed in 4 cases out of 6 papillomas. These results confirm HPV involvement in oral papilloma, leukoplakia and squamous cell carcinoma, and support the hypothesis of HPV as an etiological agent in oral carcinogenesis. However, the frequency of positive reaction was much higher in benign lesions such as papillomas and leukoplakias, than in malignant lesions like squamous cell carcinomas. Therefore, HPV may be thought to be a co-factor in oral carcinogenesis together with chemical factor, rather than a single factor. And further studies will be needed to elucidate the role of HPV in oral carcinogenesis.restrictio
