Outline of Final Research Achievements

Relationships were examined between Wnt5a expression and clinicopathologic factors in 178 consecutive cases of invasive breast cancer.(1)Wnt5a was positively expressed in 69 cases (39%) among 178 cases of invasive breast cancer. Wnt5a expression was strongly correlated with being estrogen receptor (ER)-positive.(2)Analysis of the relationship between Wnt5a expression and malignancy in exclusively 153 cases of ER-positive breast cancer led to detection of significant correlations with lymph node metastasis, nuclear grade, and lymphatic invasion. (3)Relapse-free survival was shorter in cases of Wnt5a-positive breast cancer compared to Wnt5a-negative breast cancer cases. Base on our data, Wnt5a expression can be a prognostic factor in ER-positive breast cancer.
