Methods: Tissues microarray paraffin block with 48 colorectal cancer samples were retrieved from the archives of Elrahma Medical Center. The immunostaining of cyclin D1 was performed and analyzed. Results: Cyclin D1 did not show association with clinicopathological features. There was no statistically significant correlation between Cyclin D1 immunoexpression and tumor grade, with p value > 0.05 that's considered as statistically insignificant. Conclusion: Our study indicated that; cyclin D1 immunoexpression cannot be used as a predictor of survival in colorectal cancer. It also showed no significant correlation with clinicopathological features.
