      다국어 초록 (Multilingual Abstract)

      A series of 31 patients with primary oral squamous cell carcinoma (SCC) who were treated at Chonbuk National university Hospital during the years 1991-1995,were evaluated by dual parameter analysis in flow cytometric DNA measurement,Bryne's malignancy grading system,and the TNM classification.The aims of the present study were to discover that previously undetected aneuploid clones could be detected by dual parameter analysis and to determine the prognostic value of the above parameters.
      1.Using dual parameter analysis of cytokenratin and DNA on disintegrated paraffin-embedded samples,aneuploid clones which were undetected by regular single parameter DNA analysis could be found among the cytokenratin-selected cells. DNA aneuploidy from parafin-embedded samples were 15 cases compared with 10 cases using conventional DNA analysis.
      2.The portion of aneuploid tumors showed slightly higher clinical stage tumor size than the portion of diploid tumors, but the difference was not significant.The portion of DNA aneuploid tumors showed significantly higher mean mitosis and total malignancy scores than the portion of DNA diploid tumors.
      3.The majority of the patients presented with clinical stage Ⅲ and Ⅳ lesions showed showed significantly higher mean total malignancy scores as compared to those with clinical stage Ⅰ and Ⅱ.
      4.Histopatholgic mean total malignancy score of the 31 cases was 12.7.Among the histologic parameters,mean mitosis score was correlated to the status of DNA ploidy and total malignancy score were correlated to the DNA ploidy and clinical staging.
