Vascular Endothelial Growth Factor Expression in Colorectal Adenocarcinoma of Resected Samples and its Association with Histological Grade and Pathological Stage

Mymensingh Med J. 2022 Jul;31(3):642-648.

Abstract

Colorectal carcinoma (CRC) is one of the major public health problems. Vascular endothelial growth factor (VEGF) is an effective angiogenic factor and plays a pivotal role in the development, progression and metastasis of CRC. It also could further help in selecting patients of high risk of disease progression for adjuvant therapy. Therefore, this study was undertaken to reveal the importance of angiogenic factor (VEGF) as an adjunctive tool with histologic parameters of CRC. Total 45 cases were included in this cross-sectional observational study, performed in the department of Pathology, Mymensingh Medical College, Mymensingh and Immunohistochemistry was done in the department of Pathology, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from March 2019 to February 2021. All the cases were evaluated for VEGF immunohistochemical expression. Majority of cases were low grade adenocarcinoma (86.9%) and most common stage was stage III (48.9%). Among 45 cases collectively 13 (4-negative + 9-weak positive) cases were low for VEGF expression and 32 (22-moderate positive + 10-strong positive) cases were high for VEGF expression. Statistically significant association was found with VEGF expression and increasing tumor stage as well as with lymph node metastasis (p<0.05). VEGF had positive significant correlation with stage (r=0.322; p=0.031) of tumor. However, no correlation with VEGF expression and grade (r=0.219; p=0.149) and other clinicopathological parameters of tumor was seen.
