  1. The difference between N1 and ≥ N2 was statistically significant between focal and diffuse types, and between high and low expression of CXCR4, by χ2 tests. The numbers of metastatic nodes were also significantly different between focal and diffuse types, and between high and low expression of CXCR4, by Student's t-test. N1, metastatic nodes were confined in low and mid axilla area; N2, metastatic nodes were detected at apical axilla area.
