Clinically, we show that high expressions of Aur A, FBN1 or SLUG, and low-expression of BRCA2 were significantly associated with poor disease-free and/or overall survivals, but high expression of p53 was not associated with patient survivals although p53 is commonly mutated and highly expressed in high grade serous ovarian cancer tissues, which is consistent with a previous study [28]. This evidence concerns the gene SNAI2 and ovarian serous adenocarcinoma.
