Abstract

Introduction: Colon adenocarcinoma (COAD), the fourth most common malignant cancer, has been the fifth leading cause of cancer-related death diseases worldwide. It was estimated that nearly 101,420 new COAD cases were diagnosed and 27,640 deaths in the United States in 2019. COX2 has an important role in colorectal tumorigenesis and the strong relationship between COX2/prostaglandin E2 (PGE2) signaling pathway and adenomatous polyposis coli gene (APC) expression in intestinal neoplasia and also plays an important role in carcinogenesis, suppression of apoptosis, angiogenesis, and metastasis of colon cancer.


Aim of the work: To evaluate COX2 expression in sporadic cases of colorectal adenocarcinoma in Tobruk-Libya


Patients, Materials, and Methods: The study group included 60 selected cases of colorectal adenocarcinoma, diagnosed at the Pathology department of Tobruk Medical Center, Libya, between 2016 and 2019. All patients were surgically treated and underwent right or left hemicolectomy according to the site of the tumor.


Results: The details of 60 patients selected for analyses are as follows. The mean age of the patients at initial surgery was 48.3 years (range, 38–72 years), and 42 were (70%) males and 18 (30%) were females. 18 cases of the tumors were well-differentiated adenocarcinoma (30%); 36 cases were moderately differentiated adenocarcinoma (60%) and 6 cases were poorly differentiated adenocarcinoma (10%).


Conclusion: COX2 could be used as useful markers to detect the invasiveness of colorectal adenocarcinoma. Aspirin can be used for the prevention of colorectal adenocarcinoma.
