--- Objective: To ascertain the usefulness of the IRM H2M in predicting malignancy in adnexal tumors in patients treated at HNDM between 2008 and 2010. Study: Observational, retrospective and transversal. Location: Oncologic Gynecology Service from HNDM. Population: Patients with preoperative diagnosis of adnexal tumor, between 2008 and 2010. Methods: IRM H2M index was calculated by multiplying the Sassone derived ultrasonographic score (U), menopausal status (M), Ca 125 (U/mL) and the larger diameter of the tumor (D). The X2 test was used to prove differences in M, U and D. Sensitivity and specificity of the IRM H2M index was calculated and ROC curves were generated to determine its validity (CI 95%). Results: 105 patients were included in the study. There was a significant difference between the age of the patients with benign tumors (N=85) and those with malign ones (N=20) (42.16 ± 13.43 vs 50.70 ± 12.59 years; p<0.05). The most common malign tumor was the serous cystadenocarcinoma (7.6%) and the most common benign tumor was the serous cystadenoma (32.4%). There was a strong correlation between malignancy and “U”, “M” and Ca-125. “D” did not show any relation with malignancy. The area under the ROC curve for the IRM H2M was significantly higher than every one of its individual components; the best cut off point was 346.5, with a sensitivity of 90.0% and a specificity of 90.6%.Conclusion: The IRM H2M index distinguishes reliably the adnexal benign tumors from the malign adnexal tumors. Keywords: Ovarian cancer, adnexal masses, Malignancy Risk Index.
