Kaplan Meier curves of disease free survival of risk groups for TNBC patients.

Abstract

<p>The patients were stratified into different risk groups. Two low basal (EGFR≤15% and CK5/6≤50%) risk groups: group 1 (n = 20) with low expressions/values of EGFR (≤15%), CK5/6 (≤50%), Ki-67 (≤50%), pT (≤ 3), and pN (≤ 1), and group 2 (n = 30) with low expressions of EGFR and CK5/6, and any high expressions/values of Ki-67, pT, and pN. Two high basal risk groups: group 3 (n = 106) with single high basal expression (EGFR>15% or CK5/6>50%), and group 4 (n = 36) with double high basal expressions (EGFR>15% and CK5/6>50%).</p
