There was no statistically significant difference in expression of the BRCA1 protein with the age of the patients (95% CI = 0.42–2.24, p=0.944), histological types (95% CI = 0.70–1.52, p=0.867), and tumor grade for nonserous EOC cases (95% CI = 0.51–4.41, p=0.482) as well as serous tumors (95% CI = 0.51–4.41, p=0.482). This evidence concerns the gene BRCA1 and neoplasm.
