Abstract
AIM: To investigate the expression of YB-1 and P53 in colorectal carcinoma (CRC) of different stages and to analyze their correlation with clinicopathological features of CRC.
METHODS: Expression of YB-1 and P53 proteins in normal colorectal mucosa (NCM, n = 20), low-grade colorectal intraepithelial neoplasia (LGIN, n = 30), high-grade colorectal intraepithelial neoplasia (HGIN, n = 30), and colorectal carcinoma (CRC, n = 50) was detected by immunohistochemistry.
RESULTS: The strong positive rate of YB-1 expression in NCM was significantly lower than those in LGIN, HGIN, and CRC (0% vs 76.7%, 80.0%, 80.0%, all P < 0.05). The strong positive expression of YB-1 was statistically correlated with lymph node metastasis and TNM stage in CRC (both P > 0.05). The positive rate of P53 in NCM was significantly lower than those in LGIN, HGIN, and CRC (0% vs 6.7%, 40.0%, 60.0%, all P < 0.05). The positive expression of P53 was statistically correlated with degree of tumor differentiation, lymph node metastasis and TNM stage in CRC (all P < 0.05). The expression of YB-1 was positively correlated with that of P53 in CRC (r = 0.306, P < 0.05).
CONCLUSION: YB-1 and P53 play an important role in the development and metastasis of colorectal carcinoma. Combined detection of YB-1 and P53 proteins may be useful for judging the severity and prognosis of colorectal cancer.
