BACKGROUND: The characterization of breast nodules by means of fine needle sampling is sometimes complicated due to different reasons for inconclusive results. These issues extend the diagnostic time by making further biopsies necessary with often contrasting results. For this reason, in many centers larger-sized needles are being used, replacing the cytology with the microhistology: vacuum-assisted breast biopsy (VABB) systems have a better performance, although they are often difficult to handle and more expensive. The aim of this work is to evaluate the performance of the microhistological sampling system with 13-G needle and VABB technology with no cables and easy to handle as a cutting needle.
METHODS: From January 2016 to February 2018, two operators performed a total of 86 microhistological samples with a 13-G Elite needle on BIRADS 3, 4 and 5 lesions, 30 of which were repeated after previous inconclusive cytohistological sampling. Biopsies between 5 and 43 mm were biopsied, including 70 nodules, 12 areas of non-mass echostructural alteration and 3 cysts complex.
RESULTS: The 13-G system showed 3.53% cases classified as B1, 41.17% as B2, 17.64% as B3, and 37.64% as B5. In the same period the sampling with 14- or 16-G cutting needle with the same operators showed the following results: 2.65% B1, 44.33% B2, 9% B3, 0.48% B4, 43.49% B5. The 13-G Elite sampling allowed a histological class change in 83.33% of the repeated procedures after non-definitive sampling.
CONCLUSIONS: Biopsy with TruVac system proved to be reliable and could be used to reduce cases with non-decisive cytohistological results.
