Data are presented as mean ± SEM. All other values represent the number of cases. Statistical analysis was performed using the Student's t-test or a cross-table using the Chi-squared test. P-values < 0.05 were considered significant and are shown in bold. ER, estrogen receptor; LI, labeling index; PR, progesterone receptor.
