Colorectal Carcinoma: Is There Any Correlation between Her2/neu Expression, Ki-67 Score, and Tumor Budding and Clinicopathological Parameters?-A Prospective Institution-Based Study.

Objectives: Colorectal cancer is one of the most frequent cancers worldwide and is still a major cause of cancer mortality. Her2/neu, Ki67 score, and tumor budding are independent prognostic factors in colorectal carcinomas. The objectives of the study were to evaluate Her2/neu expression, Ki67 score, and tumor budding index at invasive margin in colorectal carcinoma and find out their possible correlations with different clinicopathological factors.
