GARCIA-MANZANO, Roberto A. et al. Evaluation of the diagnostic performance of the Malignant Risk Index II in women with anexial mass diagnosis in a third level hospital. Cir. cir. [online]. 2021, vol.89, n.3, pp.321-325.  Epub Nov 03, 2021. ISSN 2444-054X.


Evaluate the usefulness of the Malignancy Risk Index II (MRI II) using diagnostic accuracy variables in 100 patients diagnosed with adnexal mass.


In a sample of 100 patients with a diagnosis of adnexal mass, demographic variables were quantified and MRI II was applied. The sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy were obtained using a 2 × 2 table and compared with the histopathological result.


MRI II with positive result was presented in 73.1% (52 patients) with malignant histopathological result and in 26.9% of patients with benign histopathological result. It presents a sensitivity in the test of 73.1%, a specificity of 70.8%, positive and negative predictive value of 73.2 and 70.8%, respectively. Diagnostic accuracy of 72%.


MRI II is a screening tool with acceptable diagnostic performance to regulate behavior, such as referring to a specialized center or requesting more specific studies in patients diagnosed with adnexal mass due to suspected malignancy.
