Figure 2. Pathological complete response (pCR) assessment in relation to the ΔSUVpeak.

Figure 2

Application of a cutoff ΔSUVpeak of >80% predicted 88% of overall non-pCRs A. and 89% of axillary lymph node (ALN) non-pCRs C. in the HER2-negative group, displaying higher negative predictive values of 94% and 89%, respectively. In the HER2-positive group, ΔSUVpeak could not predict overall B. or ALN pCRs/non-pCRs D. because a clear cutoff could not be defined. ΔSUVpeak refers to the difference in standard uptake values between baseline and after two chemotherapy cycles.
