RADIATION DIAGNOSTICS OF PRIMARY MULTIPLE MALIGNANT NEOPLASMS AFFECTING THE GASTROINTESTINAL TRACT AND FEMALE REPRODUCTIVE ORGANS

Abstract

The purpose of the study is to study the information content of radiodiagnosis of primary multiple malignant neoplasms (PMMN) of the gastrointestinal tract and female reproductive organs. The relevance is due to the annual increase in the number of newly diagnosed cancer patients, including polyneoplasia. Radiation diagnostic technologies were used: ultrasound, X-ray computed tomography and magnetic resonance imaging. Statistical analysis was carried out using medical statistics methods (significant differences - p ≤ 0.05). Damage to the gastrointestinal tract among patients with PMMN was diagnosed in 385 (average age - 55.2±2.9 years), there were fewer women among them (173 women, 44.9%) than men. Synchronous malignant neoplasms (MNT) of the gastrointestinal tract (GIT) were identified in 96 patients (24.94%), metachronous - in 289 (75.06%). A combination of metachronous cancers of the gastrointestinal tract and endometrium was found in 14 (4.8%), breast – 25 (8.6%), myometrium – 9 (3.1%), cervix and ovaries – 3 cases each (1.04 %). Synchronous PMZN with damage to the gastrointestinal tract and liquid waste: esophagus - endometrium - 1 case (1.04%); stomach – mammary gland, stomach – body of the uterus – 1 case each (1.04%); colon – mammary gland and colon – ovaries – 4 cases each (4.2%); colon - cervix and colon - endometrium - 1 case each (1.04%). The information content of complex radiation diagnostics was: sensitivity – 90.28%, specificity – 91.43%, accuracy – 90.85%. To identify polyneoplasia, it is necessary to use all radiation diagnostic technologies in the patient examination algorithm both at the screening stage and at the stage of primary and differential diagnosis of primary multiple and metastatic tumors of the digestive organs and all other systems.
