  1. P-value determined by chi-square test. * P-value of the correlation between CCNB-2 expression and clinicopatholigical parameters. ¤ P-value of hazard ratio (HR). BRE, Bloom, Richardson, Elston/Ellis; CI, confidence interval. All parameters were coded as 0 (negative) and 1 (positive) except as noted. Pathologic tumor size was coded as 1 (0-20mm), 2 (>20-50mm) and 3 (>50mm). Histologic type was coded as 1 (ductal), 2 (lobular ductal), 3 (ductal and lobular) and 4 (other). (N) = No. of patients (%).
