Abstract: Objective To investigate the corresponds between NF-κB p65 activation and k-ras mutations.Methods NF-κB p65 activation was analyzed by immunochemistry in 167 colorectal cancer specimens in which the k-ras mutation status was confirmed.Resluts Among 167 colorectal cancer specimens screened,59 (35.3 ％) had k-ras mutations and 63 (37.7 ％) had NF-κB p65 activation.k-ras mutations and NF-κB p65 nuclear expression were no significant difference in different sex,age,ECOG score,pathological types,degrees of pathological differentiation,TNM stage,and metastases on lymph nodes (P＞ 0.05).The positive nuclear expression rate of NF-κB p65 was 50.8 ％ (30/59) in specimens with k-ras mutations and 30.6 ％ (33/108) in specimens with wild type k-ras.There was obviously statistical difference between them (P =0.010).Conclusion NF-κB p65 activation in coloretal cancer was associated with k-ras mutations.
