Amino acid profiles of patients with cancer. The results of receiver-operator characteristic curve (ROC) analysis of plasma amino acids before and after complete surgery. Area under the ROC (AUC) for amino acids used to calculate API values are shown for all patients (n = 94) (a), patients with cervical cancer (n = 22) (b), patients with endometrial cancer (n = 53) (c), and patients with ovarian cancer (n = 19) (d). HC, healthy control; pre, pre-surgery; and post, post-surgery. Axes show the AUC of each amino acid
