Yu FH, et al. - In patients with early-stage invasive breast cancer (EIBC), researchers used multivariable logistic regression analysis to establish a radiomics nomogram integrating clinical factors and radiomics characteristics from ultrasound for the preoperative diagnosis axillary lymph node (ALN) status. Four hundred and twenty-six manually segmented ultrasound images of EIBC patients were enrolled between September 2016 and December 2018, divided into a primary cohort (n = 300) and a validation cohort (n = 126). According to this retrospective study, as a non-invasive and reliable tool in predicting ALN metastasis, the radiomics nomogram could hold promise and can facilitate the development of more effective preoperative decision-making.
