COMPARISON OF IMMUNOHISTOCHEMICAL EXPRESSION OF INSULIN LIKE GROWTH FACTOR 1 RECEPTOR (IGF-1R) IN BENIGN AND MALIGNANT SALIVARY GLAND TUMORS

Objectives: To evaluate the difference in immunohistochemical expression of insulin-like growth factor-1 receptor (IGF-1R) in diagnosed cases of benign and malignant salivary gland tumors.Materials and Methods: This Comparative Cross-Sectional Study was conducted at the department of Pathology, Peshawar Medical and Dental College, Peshawar. A total of 100 Salivary Gland Tumors from 56 male and 44 female patients were included in the study, with an average age of 43.50 ± 15.21. The Immunohistochemical Expression of Insulin-like Growth Factor 1 Receptor was determined on both benign and malignant salivary gland tumors using the Bio SB Polyclonal IGF-1R antibody (rabbit, BT-AP04398). The collected data were analyzed using SPSS version 25.Results: For the immunohistochemical expression of IGF-1R on benign and malignant salivary gland tumors, the Allred Scoring method was utilized. P value of <0.05 was considered significant, but no positive signifi cance was found between the expression of IGF-1R and salivary gland tumors.Conclusion: IGF1R expression was positive in various SGTs but no statistically significant difference was seen in multiple histopathological types of benign and malignant SGT
