The prediction effect of pCR and the prognosis by a combination of the prediction model and ctDNA monitoring. A The pCR prediction determined by the chemotherapy predictive model constructed by combining the information from the established tumor prediction model (including DNA mutations and clinical factors), along with the information from ctDNA status. B Different chemotherapy predictive models are established using random forest based on the expression status of ctDNA at different time points of T0, T1, and T2. C The predictive effect for the chemotherapy predictive model on the prognosis of NAC patients. D Kaplan–Meier curves for patients in high- and low-risk group
