Abstract:
Objective To explore the clinicopathological value of X-ray repair cross complementing gene 1(XRCC1) expression in colorectal carcinoma. Methods The XRCC1 gene expression in 107 cases of colorectal carcinomas, 25 cases of adjacent mucosa and 36 cases of normal colorectal mucosa was detected immunohistochemically, and the correlation between the expression and clinicopathological factors was analyzed. Results The positive rates of XRCC1 expression in colorectal carcinoma and adjacent mucosa,87.8 % (94/107) and 84.0 % (21/25) respectively, were significantly higher than that in the normal colorectal mucosa [27.8 %(10/36) (P=0.000, P =0.000)]. In colorectal carcinoma, the positive rate of XRCC1 expression in the group of poor differentiation [44.4 % (4/9)] was significantly lower than that in the groups of moderate and well differentiation [94.8 % (50/58)(P=0.000) and 87.5 %(35/40) (P=0.015)], while the positive rate of XRCC1 expression was not related to sex, age, location, infiltration depth and lymph node metastasis (P ＞0.05). Conclusion The results indicated that XRCC 1 protein can be used as a marker to diagnose colorectal carcinoma.
