The distribution of clinical characteristics in our 44 sporadic breast tumors. Estrogen receptor-α status is denoted as ER+ and ER-. Clinical outcome for the patients is represented by M+ (distant recurrences within 6 years) and M- (no recurrences within a follow-up period of at least 5 years). Microarray data were generated as described by Gruvberger et al. [8].
