There was no statistical association between the Ki67 and the age, the tumor size, and the number of the positive axillary lymph nodes (p values 0.412,0.529, and 0.429) respectively, these results are similar to one of our previous studies in which we correlated the positive and the negative levels of Ki67 and we depended on a cut off level of 14% to categorize the positive and the negative groups because Ki67 is expressed at low levels in normal tissues, however in this study we correlated the quantitative level of Ki67 expression with various patient and tumor characteristics [4,14]. This evidence concerns the gene MKI67 and neoplasm.
