METHOD FOR DIFFERENTIAL DIAGNOSIS OF BENIGN AND MALIGNANT NEOPLASMS OF OVARIES Russian patent published in 2019 - IPC A61B8/08 A61B5/1468 

FIELD: medicine.

SUBSTANCE: invention refers to gynaecology and oncology, and can be used for differential diagnosis of benign and malignant ovarian formations. Quantitative assessment is carried out in points of malignancy risk by formula AxBxC. A - features of the woman's age: reproductive age - 1 point, postmenopause - 4 points. B - presence of such ultrasonic signs as multi-chamber formation, solid formation, bilateral defeat, presence of ascites, presence of metastases. If observing no ultrasound sign B is equal to 1 point. If observing from two to five signs B is equal to 4 points. C is concentration of tumour marker HE-4 (pmol/l) in blood serum. Index value more than 170 in patients of reproductive age and more than 340 in postmenopausal women enables to predict malignant nature of ovarian formations.

EFFECT: method provides differential diagnosis of benign and malignant ovarian formations by using ultrasound findings and use as a tumour marker in blood serum HE-4.
