[Compatibility of the results of ultrasound-guided fine needle aspiration biopsy with the histological findings in assessment of focal breast lesions among woman attending the outpatient breast clinic].

Continuous increase of morbidity and mortality rate due to breast cancer has led to development of new diagnostic methods that are aimed at detecting neoplastic and preneoplastic lesions in their early, yet asymptomatic stages. Development of modern imaging techniques (ultrasonography, mammography, magnetic resonance) and invasive diagnostic procedures (fine needle aspiration biopsy, core needle biopsy, stereotactically guided biopsy) allows to detect lesions not exceeding 1 cm in diameter, and therefore may provide a complete cure. The aim of this study was to estimate diagnostic usefulness of ultrasound-guided fine needle aspiration biopsy in detecting benign breast dysplasia (with and without proliferation of ductal epithelial cells), benign neoplastic lesions and breast cancer, as well as to determine compatibility between US-guided FNAB results and subsequent histological findings. The study group consisted of 213 female patients. The obtained results were subject for statistical analyses that revealed a high degree of compatibility between US-guided FNAB and histological results (93.6-95.5%), and also confirmed high sensitivity of US-guided FNAB. This method has proved to be an efficient diagnostic tool for early detection of benign breast dysplasia, benign neoplasms and breast cancer, making early surgical treatment possible in most cases and permitting omission of an intra-operative histological examination.
