Receiver operating characteristic curves to predict pCR. Receiver operating characteristic curves for the ability of (A) the radiographic response (using the mRECIST measurement method), B AFP response, and C the radiographic response combined with AFP response to predict pCR, respectively. A included all 35 patients; B and C only included 25 patients who had positive AFP at baseline. AFP, α-fetoprotein; AUC, area under the receiver operating characteristic curve; mRECIST, modified Response Evaluation Criteria in Solid Tumors; pCR, pathologic complete response
