| Introduction: The most common oral cancer is Squamous Cell Carcinoma
(SCC) that a wide variety of environmental factors has caused complex etiology
in terms of prevalence presentation also a significant correlation between the
levels of WT1 expression and prognosis of the disease has been reported.
Materials and Methods: For This descriptive - analytical study samples
were collected from the archives of Pathology Department of Imam Reza
Hospital Tabriz and Department of Pathology of Dentistry School. In this study,
data from patients’ records and results of Immunohistochemical staining (IHC)
were collected in the laboratory. After a review of the histopathologic grade we
compared them with the data records to ensure the accuracy grade and then
were compared with the results of immunohistochemistry. Chi-square test and
comparison of independent groups was analyzed using statistical software
spss16.
Results: From 45 cases, expression of WT1 has been reported in 3 cases
(6.2%) and all of them were well-differentiated. The mean age of the participants
was 66.42 (±16.06) years, which 16 cases were female (35.6%) and 29 cases
were male (64.6%). Histopathologic grade was well-differentiated in 36 cases
(80%), 2 cases had poorly-differentiated grade (4/4%), and moderatelydifferentiation
was reported in 7 cases (6.15%). There was not significant
relation between histopathologic grade and WT1 expression.
Conclusion: Further studies about investigating of the possibility of
treatment with immunotherapy based WT1 peptide as an effective treatment in
cases with increased expression of WT1, are suggested. |
