Preoperative Factors Associated with Infiltrative Histologic Growth Patterns in Extremity Soft Tissue Sarcoma

Figure 3

Pairwise AUC comparison of the predictive index and the tumor border on MRI alone or histological subtype other than liposarcoma alone in predicting infiltrative histologic growth pattern. (a) Pairwise area under the receiver-operating curve (AUC) comparison of the predictive index and the tumor border on MRI alone in predicting infiltrative histological growth pattern. (b) Pairwise area under the receiver-operating curve (AUC) comparison of the predictive index and histological subtype other than liposarcoma alone in predicting infiltrative histological growth pattern. AUC, area under the curve. The dashed line in both graphs represented random guess to predict (AUC = 0.500).
