We also found that expression of NgBR and survivin has statistically significant correlations in the Stage II (correlation = 0.448, p<0.05) and Stage III–IV (correlation = 0.386, p<0.05) of ductal adenocarcinoma samples, but there are no statistically significant correlations in normal and Stage I groups (Table 4). This evidence concerns the gene BIRC5 and invasive ductal breast carcinoma.
