    A Case of Invasive Ductal Carcinoma with Axillary Skip Metastasis Confined to the Interpectoral (Rotter's) Lymph Node. (PubMed, Surg Case Rep)
    This extraordinarily rare case of axillary skip metastasis limited to the interpectoral node emphasizes the potential for false-negative SN biopsies. Careful review of preoperative images, particularly MRI images, is crucial to avoid understaging. Awareness of interpectoral node involvement may help guide appropriate treatment strategies for selected patients.

    Identifying immune-related predictive factors for post-eribulin therapy in patients with HER2-negative advanced breast cancer- a multicenter retrospective study. (PubMed, Int J Clin Oncol)
    An ALC ≥ 1000/μL at ERI completion was associated with an improved post-ERI OS (OS2). It is suggested that not only the factors at the initiation of ERI, but also the immunological status at the end of ERI, may have prognostic value after ERI.
