Abstract
Prostate cancer is the most common noncutaneous malignancy among men worldwide, including in Sudan, where it represents a significant public health challenge. CD147, a transmembrane glycoprotein implicated in tumor progression, invasion, and metastasis, has shown potential as a prognostic biomarker in various cancers. This retrospective case-control study aimed to evaluate CD147 expression in prostate adenocarcinoma among Sudanese men and its association with tumor grade. A total of 80 paraffin-embedded tissue samples, including 40 cases of prostate adenocarcinoma and 40 benign prostatic hyperplasia (BPH) controls, were analyzed using immunohistochemistry. CD147 expression was observed in 22.5% of adenocarcinoma cases compared to 7% of controls; however, the association was not statistically significant (p=0.07). Low-grade tumors were predominant in the cohort, consistent with early-stage diagnoses. The findings revealed no clear link between CD147 expression and tumor grade, diverging from prior studies that associate CD147 with advanced tumor stages. The nonsignificant results may be attributed to the small sample size, emphasizing the need for future research with larger, more diverse cohorts, advanced molecular techniques, and functional studies to better elucidate the role of CD147 in prostate cancer pathogenesis and its potential as a therapeutic target.
