Abstract:
Objective to investigate the role of Pim‐3 and NF‐κB in the development and progression of infiltrating ductal carcinoma of the breast .Methods Here ,we used immunohistochemistry to detect expression of Pim‐3 and NF‐κB in 75 samples of infiltrating ductal breast carcinoma ,21 samples of intraductal breast carcinoma and 30 normal breast tissues .The relationship of their expression ,as well as their correlation with clinicopathological features and patient survival were assessed .Results In con‐trast ,both Pim‐3 and NF‐κB were more commonly detected in infiltrating ductal carcinoma than in intraductal carcinoma and normal tissue .In the infiltrating ductal carcinoma ,the positive expression rate of Pim‐3 was 77 .3% ,and that of NF‐κB was 68 .0% ;in duc‐tal carcinoma of the breast ,the positive expression rate of Pim‐3 was 52 .4% ,and that of NF‐κB was 42 .9% ;in the normal breast tissue ,the positive expression rate of Pim‐3 was 23 .3% ,and that of NF‐κB was 16 .7% ;the positive expression rate of Pim‐3 was correlated with tumor size ,histological grade ,and clinicopathological stage ;and that of NF‐κB was correlated with tumor size ,histo‐logical grade ,lymph node metastasis of breast cancer .Spearman rank correlation analysis revealed a positive correlation between Pim‐3 expression and NF‐κB expression in infiltrating breast cancer (r=0 .243) .Conclusion Our results demonstrate that Pim‐3 and NF‐κB play a role in the initiation and development of breast cancer ,thus ,these proteins may serve as useful diagnostic and prognostic markers of invasive breast cancer .
