ABSTRACT

Background: women with a breast cancer diagnosis are five times more likely to develop a tumor in the contralateral breast. More than 16% of contralateral metachronous cancers have reported metastasis. Even with normal results from mammograms and physical exploration at the time of diagnosis, contralateral cancer is detected subsequently in 10% of cases. A patient in such conditions must undergo a second treatment which could have been could have been administered from the outset if it had been detected sooner; consequently, treatment can be considered delayed in such cases. Screening by magnetic resonance helps detect contralateral cancer in up to 5% of such patients.
Objectives: assess the usefulness of magnetic resonance in searching for multifocality or multicentricity in patients with diagnosis of breast cancer, in order to provide objective and timely treatment for each patient. Correlate compatible findings in magnetic resonance with pathology reports.
Materials and methods: all patients who underwent magnetic resonance studies of breasts, over a total period of four years, who had a prior histopathological diagnosis of breast cancer, were included. The results were correlated with mammogram or ultrasound studies. The magnetic resonance reports on patients with suspicious findings were correlated with compatible results from pathology.
Results: 21 patients were included in an age range of 34 to 69 years, with a mean age of 48. New lesions were found in the patients, the majority benign, over-aggregated; in two patients (9.5%) new malignant lesions were found, leading to changes in the previously planned treatment regime.
Conclusions: the capacity of magnetic resonance to detect multifocality was confirmed, influencing patients’ treatment and prognosis.
