Evaluation of Tumor Associated Macrophages and Vascular Endothelial Growth Factor Receptor expression in Colorectal Carcinoma: An Immunohistochemical Correlation Study
Abstract: Colorectal cancer (CRC) is one of the most common malignancies worldwide and its progression is influenced by the tumor microenvironment. Tumor-associated macrophages (TAMs), particularly the M2 phenotype, play a critical role in tumor progression, immune suppression and angiogenesis. Vascular endothelial growth factor receptor (VEGFR) signaling is a major driver of tumor angiogenesis. This study aimed to evaluate the correlation between tumor-associated macrophages and VEGFR expression in colorectal carcinoma using immunohistochemistry. A cross-sectional study was conducted on 52 cases of colorectal carcinoma received in the Department of Pathology, Osmania General Hospital, Hyderabad. Immunohistochemical staining was performed for CD163 to identify tumor-associated macrophages and VEGF to evaluate angiogenic activity. Expression levels were scored semi?quantitatively and correlated with clinicopathological parameters. Statistical analysis was performed using Spearman correlation and Chi-square tests. A strong positive correlation was observed between CD163 and VEGFR expression (Spearman ? = 0.659, p
