Abstract
Objective: The loss of expression of syndecansyndecan-1 is associated with poor prognosis in many types of human cancer. The objective of this study was to evaluate the relation between syndecan-1 immunoexpression and several clinicopathological parameters in a subset of colorectal carcinoma (CRC) patients.Methods: Pathology tissue blocks of 202 primary tumors, 41 adenomas, and 37 normal colonic mucosae were used in this study. The cases diagnosed in the period 1995–2015 was included in the study. Immunohisto chemistry analysis was performed using anti-CD138/syndecan-1 (B-A38) mouse monoclonal antibody. A semiquantitative method was used to score the syndecan-1 expression based on an evaluation of the percentage and intensity of the membranous and cytoplasmic expression. The data collected from Pathology Department at King Abdulaziz University Hospital, Jeddah, Saudi Arabia. This is a retrospective cohort study that was conducted from July 2018 until August 2019.Results:Loss of syndecan-1 immuno expression was observed in 72 (42.6%), 5 (12.2%), and 3 (8.1%) cases of CRC, adenomas, and normal mucosae, respectively. Low expression of syndecan-1 showed an association with nodal (p=0.003) and distant (p=0.001) metastasis, lymphovascular invasion (p=0.001), and tumor recurrence (p=0.006). Low syndecan-1 expression were associated with short overall survival (OS) (log rank 4.019, p=0.045) and disease-free survival (DFS) probabilities (log rank 4.748, p=0.029).Conclusion: Loss of syndecan-1 immuno expression is associated with metastatic potential, tumor recurrence and shorter survival in CRC and is considered a potential biomarker of poor prognosis in CRC patients.
