Introduction
Colorectal cancer (CRC) incidence is increasing globally. It is ranked as the second most common cancer in women and the third most in men. Angiogenesis plays a significant role in the development and spread of colorectal cancer. Angiogenesis has been proposed as a prognostic marker in a variety of human neoplasms. In this regard, markers of angiogenic endothelial cells are emerging as targets for cancer therapy.
Aim of the Work
The aim of this study is to evaluate the prognostic impact of tumor angiogenesis assessed by microvessel density (MVD) counting using CD31 and CD105 along with VEGF immunostaining in colorectal cancer patients.
Methods
VEGF, CD31, and CD105 expressions were evaluated using immunohistochemical staining in 50 patients with colorectal cancer. The relationship between their expressions and clinicopathological factors and outcome of patients were analyzed.
Results
The VEGF expression (70% of the cases) correlated significantly with larger tumor size, higher grade, and advanced tumor stage (p = 0.006, p < 0.001, p < 0.001), respectively. The mean MVD was 24.2 ± VMD by CD105 (p = 0.10.65 019 for CD105, 19.2 ± 8.41 for CD31, respectively. MVD by CD31 (p = 0.023)) and was significant predictive factors for overall survival. Furthermore, the VEGF expression (p = < 0.001) was a significant predictive factor for DFS. There was a statistically significant association between the recurrence rates with both VEGF and CD105 (p < 0.001) but not significant with CD31.
Conclusion
CRC patients with high VEGF, CD105, and CD31 expression showed poor prognosis. The immunohistochemical markers could be used for stratification of patients into low-risk and high-risk groups.
