Abstract

The translationally controlled tumor protein (TCTP) is a highly conserved protein involved in a variety of normal cell functions and disease processes. Preclinical studies revealed that TCTP has anti‑apoptotic properties, promotes cell growth and division and is involved in cancer progression by promoting invasion and metastasis. The present study explored the potential value of TCTP as a prognostic marker in colon cancer. A retrospective analysis of 74 patients with colon cancer was performed. Using immunohistochemistry, TCTP levels in the primary tumor were assessed semi‑quantitatively by the calculation of cytoplasmic and nuclear H‑score. Cytoplasmic TCTP levels in the primary tumor had no statistically significant association with disease‑free survival (DFS), progression‑free survival (PFS) and overall survival (OS) in the present patient population. Patients whose primary tumors had a negative nuclear TCTP expression had significantly improved clinical outcomes. The PFS for the negative nuclear TCTP expression group was 7.7 months [95% confidence interval (CI), 5.8‑9.5] compared with 5.5 months (95% CI, 3.2‑7.8) in the group with positive nuclear expression (P=0.023, Mantel‑Cox log‑rank). Patients with a negative nuclear expression of TCTP had a significantly higher median OS (22.2 months; 95% CI, 16.1‑28.3) compared with those with positive TCTP nuclear expression (median 13.2 months; 95% CI, 10.1‑16.3; P=0.008, Mantel‑Cox log‑rank). In a multivariate Cox regression model, a positive nuclear TCTP H‑score was an independent risk factor for worse PFS and OS. The 1‑year OS rate in the group with negative nuclear TCTP expression was 86.3% compared with 56.5% in patients with positive nuclear TCTP expression (P=0.008). The present study suggested that semiquantitative H‑score measurement of TCTP levels in the nuclei of tumor cells from the primary tumor is a potential prognostic marker for clinical outcomes in patients with colon cancer.
