Based on their ß coefficients, axillary cCR after NAC evaluated on imaging (β = 1.07) was matched with a score of 98, ER-/HER2-breast cancer (β = 0.80) with a score of 73, ER-/HER2+ subtype (β = 0.97) with a score of 89, ER+/HER2+ subtype (β = 0.61) with a score of 56, Ki67 > 14% at CB (β = 0.55) was matched with a score of 50, NACT's Type3 (β = 0.76) was matched with a score of 70, and histological tumor type at core biopsy “Others” (β = 0.71) with a score of 65. This evidence concerns the gene MKI67 and breast cancer.
