This study aimed to investigated whether hypermethylation of APC promoter, the aggressive behavior of breast cancer cells, and correlated them with clinicopathological parameters and survival. Methods: Sixty-one fresh tissues of breast tumor were evaluated for APC promoter hypermethylation with methylation-specific PCR techniques (MS-PCR) and  APC mRNA expression level analysis by quantitative real-time reverse transcription-PCR. Results: Our results show aberrant APC hypermethylation status was founded in 27 of 61 cases (44%), and significantly associated with chemotherapy treatment (OR= 6.9, 95%CI=1.5-31.01, P = 0.01), distant metastasis (OR = 5.52, 95%CI = 1.27-24.08, P = 0.04) as well as APC methylated status also associated with shorter overall survival than those without (8.4 and 11.0 years respectively, P = 0.02). Conclusion: The findings indicated hypermethylation of APC promoter may be used as a useful prognostic biomarker in breast cancer patients. %U https://journal.waocp.org/article_89393_cd0bd1a7327afcd356fd6715ea240535.pdf
