Fig. 3From: The dynamic monitoring of CEA in response to chemotherapy and prognosis of mCRC patientsROC curve constructed the relationship between CEA change and radiological tumor response assessed by RECIST criteria. a. CEA change from baseline to 12 weeks could predict radiological tumor response to chemotherapy; b. CEA change ratio from 12 weeks to 18 weeks could predict the radiological progression.
