Figures & data
Figure 1. Correlation between subtypes of the index tumor (marked with blue) and contralateral breast cancer (Contra, marked with red) or local recurrence (Local, marked with red). Surgical treatment of the index tumor was either mastectomy (Mastec) or breast conserving surgery + radio therapy (BCT). Local recurrence (Local) was subdivided into three subgroups: if primary treatment was mastectomy, if primary treatment was BCT and recurrence was developed in the scar or if primary treatment was BCT and recurrence was most likely outside the scar. Younger: ≤45 years, older >45 years.
Figure 2. Relationship between intrinsic subtypes of the primary index tumor and local recurrence or contralateral breast cancer. Intrinsic subtype classification was based on either RIS4 (A) or PAM50 (B).
Figure 3. Relationship between intrinsic subtypes on RIS4 and PAM50.
