OBJECTIVE:

To determine the correlation between the risk of malignancy index Jacobs II and anatomopathological result in ovarian tumors.

MATERIALS AND METHODS:

Observational, retrospective, prospective, analytical and transversal study of patients with a diagnosis of ovarian tumor with tumor marker of Ca 125 and the result of pathology admitted to the Christus Muguerza Conchita Hospital in Nuevo León during a 2-year period (2016-2018). Risk of malignancy index Jacobs II was calculated: IRM = U x M x Ca 125. Two groups were divided according to the results of histopathology (benign and malignant). For variables of central tendency, were compared with Student&apos;s t-test adjusted to two-tailed normality (P <0.05). For categorical sampling, compared with the 2-tailed Fisher&apos;s test to describe the differences between the groups or distribution c2 (P <0.05). The sample was studied to observe risk / benefit factors (AUROC) as well as determination of the odds ratio, relative risk, sensitivity, specificity and creation of the logistic regression model of the indicators of interest.

RESULTS:

It was found that patients with a Jacobs II malignancy index higher than 155.22 (AUROC 0.95) were more likely to have a malignant lesion due to pathology with 88% sensitivity and 91% specificity.

CONCLUSION:

There is a correlation between the risk index for malignancy of Jacobs II and the anatomopathological result in ovarian tumors.
