Figure 4. Overall survival curves according to the expression of B-cell CLL/lymphoma 2 (BCL2) in each subtype classified by each stage. Survival curves for HR(+)/HER2(−) in stage I (A), stage II (B), stage III (C), for HR(+)/HER2(+) in stage I (D), stage II (E), stage III (F), for HR(−)/HER2(+) in stage I (G), stage II (H), stage III (I), and for HR(−)/HER2(−) in stage I (J), stage II (K), stage III (L) subgroups.

HR=hormonal receptor; HER2=human epidermal growth factor receptor 2.
