There is an error in the penultimate sentence of the Abstract. The correct sentence is: Multivariate analysis which incorporated variables of patients' age, tumor size, grade, and lymph node metastasis revealed that BRCA1 promoter methylation was associated with overall survival (p = 0.027; hazard ratio, 16.38) and disease-free survival (p = 0.003; hazard ratio, 12.19).
