Abstract:
BACKGROUND:The clinicopathological roles and relationships of hTERT, p21 and p53 proteins have not been studied in depth in colorectal cancer. The aim of the present study is to investigate the clinicopathological roles of expression of hTERT protein expression and its relationship with the expression of p21 and p53 proteins in a large cohort of patients with colorectal adenocarcinoma. MATERIALS AND METHODS:Expressions of hTERT, p21 and p53 proteins were investigated in 188 patients with colorectal adenocarcinomas by immunohistochemistry. The findings were correlated with the clinicopathological features and survival data of colorectal adenocarcinomas. RESULTS:hTERT, p53 and p21 proteins were detected in 63%, 100% and 62% of the patients with colorectal carcinoma. High level of hTERT protein expression was noted in patients with metastases (p = 0.038) and in patients with rectal cancer (p = 0.046). Loss or low level of p21 protein was often noted in non-mucinous colorectal adenocarcinoma when compared with mucinous adenocarcinoma (p = 0.001). Furthermore, p53 expression was more frequently noted in non-mucinous adenocarcinoma (p = 0.001). The level of expression of p21 protein was positively correlated with expression of level of hTERT protein (p = 0.00001). The survival of the patients was related to staging (p = 0.001) and p53 protein expression (p = 0.038) of the tumours. CONCLUSIONS:hTERT protein expression is an indicator of the biological aggressiveness of the cancer. The level of expression of the protein was also related to the distal location and level of p21 expression of the tumours.
