Can Replacing CA125 with HE4 in Risk of Malignancy Indices 1–4 Improve Diagnostic Performance in the Presurgical Assessment of Adnexal Tumors?

Figure 4

Diagnostic accuracy of classical and modified risk of malignancy indices (RMIs) 1–4 for differentiation of malignant stage I (FIGO) from nonmalignant adnexal masses. Modified RMIs were obtained by replacing cancer antigen 125 with human epididymis secretory protein 4 in the classical RMI. Diagnostic accuracy was based on receiver operating characteristic analysis. Diagonal segments are produced by ties.
