A large number of clinical data have confirmed that the prognosis of breast cancer patients is closely related to the presence or absence of axillary lymph node metastasis [Recent studies have shown that radiomics have a good predictive power for evaluating LNM various cancers [Studies have demonstrated the potential application of PET radiomics in the diagnosis, staging, and assessment of treatment response in breast cancer [Previous studies have often predicted LNM by the volume of the primary tumor and its metabolic parameters. For example, studies by De [Limitations of this study are that it was a retrospective single-center study with possible selection bias; patients with multifocal lesions, bilateral lesions, and occult lesions were excluded because it was difficult to identify lesions that would lead to LNM; and only internal validation was performed due to the volume of data, which needs to be expanded for external validation.
