Abstract
IntroductionSecond-look ultrasound (SLU) is useful to characterise new lesions identified by magnetic resonance imaging (MRI). SLU may also help to optimise surgical treatment since it allows the performance of biopsies and histopathological analysis of the lesions. The aim of this study was to determine the utility of SLU to identify and characterise lesions initially detected by MRI, as well as its subsequent influence on surgical management. Material and methodWe performed an observational retrospective study that included women diagnosed with breast cancer who underwent SLU after MRI between 2013 and 2015. We collected data on epidemiological factors, the primary tumour, the characteristics of the lesions identified by MRI and subsequently by SLU, surgical procedures, and histopathological results. ResultsA total of 168 new lesions were identified by MRI in 110 patients. Of these, 123 (73.2%) were subsequently identified in SLU. Using the BI-RADS system, 88 (71.6%) lesions were classified as BI-RADS3 and 24 (19.5%) as BI-RADS4. The result of biopsy after SLU was malignancy in 17 lesions, leading to a change of surgical management in 15 patients. ConclusionsSLU can be useful to optimise the surgical treatment of patients with breast cancer and detection of a new lesion by MRI. SLU allows these lesions to be characterised and localised and biopsies to be taken. This in turn allows histopathological analysis, which helps to determine the need for extirpation of the lesion.
