Clinicopathological Value Of Epidermal Growth Factor Receptor (EGFR) And Ki-67 Expression In Colorectal Adenoma And Adenocarcinoma.

Objectives: To evaluate epidermal growth factor receptor and Ki-67 immunohistochemical expression in colorectal adenoma and carcinoma cases, and to relate their expression with the available clinicopathological data.

Method: The retrospective study was conducted at the Faculty of Medicine, Kafrelsheikh University, Egypt, from September 2019 to October 2020, and comprised formalin-fixed and paraffin-embedded specimens related to cases of colorectal adenoma and those of colorectal carcinoma, who had no previous radiation or chemotherapeutic treatment. Immunohistochemical staining of all thecases was done using anti-epidermal growth factor receptor and anti-Ki-67 antibodies.
