Significance of Immunohistochemical Expression of Fascin-1 in Colorectal Carcinoma

colorectal carcinoma is an aggressive malignant tumor. It has high incidence of cancer-related morbidity and mortality. the malignant potential of a given neoplasm is based mainly on its ability to invade the surrounding vasculature and reach to distant sites, the latter is called metastasis. in order to metastasize to distant sites, the neoplastic cells must re-arrange the intracellular actin filaments into well formed intracellular assembly which enable the neoplastic cells to reach to distant sites. Fascin-1 is an actin binding protein, it is involved in reconstruction of actin assembly. fortunately, Fascin-1 could be blocked by newly developed medications, blocking of Fascin-1 may limit the metastasis of colorectal carcinoma. in current study the investigators detect Fascin-1 in colorectal carcinoma by immunohistochemical approach, then they correlated different levels of Fascin-1 expression to tumor clinical and pathological criteria as patients' ages, sexes, tumor stages, nodal metastasis, vascular and per-ineural invasions.
