Interestingly, after stratification for the presence of microcalcifications (N = 21), CPB1 expression alone identified 93.3% of the DCIS (N = 8) in the group of patients having microcalcifications and 100% after the inclusion of age at mastectomy and BMI into the model (Figure S3C). The gene discussed is CPB1; the disease is ductal breast carcinoma in situ.
