The prognostic activity of transforming acidic coiled-coil 3 (TACC3) immunohistochemical expression in colon adenocarcinoma patients

INTRODUCTION: Colorectal cancer is most common in developed countries. Each year, more than one million people develop colon cancer, and nearly 70,000 people die from the disease. Although medicine has made great strides in the treatment of colorectal cancer, the prognosis of patients is still poor. It is difficult to find the main cause of colon cancer, so it is necessary to introduce new methods that will accurately diagnose the cause of this malignancy. MATERIAL AND METHODS: Paraffin-embedded colon adenocarcinoma samples (n = 97) were assessed immunohistochemically for TACC3 protein. Connections between TACC3 immunoexpression and clinicopathological factors, including the 5-year overall survival (OS), were evaluated. RESULTS: Immunohistochemical expression of TACC3 protein in colon adenocarcinoma samples and non-pathological samples of colon tissue was described as weak, moderate, or strong. As demonstrated, the level of the TACC3 immunohistochemical reactivity was not correlated with demographic factors including gender and age, and clinicopathological factors. The average survival time for all the patients was 36.8 months (95% CI: 33.134–40.536). A multivariate analysis demonstrated that the grade of tumour differentiation (HR = 2.740; 95% CI: 1.864–4.027, p < 0.001) and TACC3 immunoexpression in healthy tissues (HR = 1.700; 95% CI: 1.073–2.694) were independent risk factors for worse survival of patients. CONCLUSIONS: The high level of TACC3 immunoexpression in cancerous tissue was not associated with malignancy-related clinicopathological factors and 5-year overall survival of patients.
