A. Distribution of APRIL (black bars) and BAFF (gray bars) immunoreactivity in different areas of breast cancer specimens. The intensity of staining was determined by the use of H-score, as described in the Material and Methods section. Mean ± SEM is presented. Asterisk indicates significantly different results (p < 0.05 at least) as determined by ANOVA with post-hoc mean comparison, after application of the Bonferroni correction. B. Distribution of APRIL immunoreactivity in node-negative (n = 4) and node-positive (n = 35) patients. Mean ± SEM is presented. C. Distribution of APRIL and BAFF immunoreactivity according to the Grade of patients. Mean ± SEM is presented.
