The diagnostic criteria have been constantly updated by the World Health Organization (WHO) with increasing understanding, most recently in 2019. Focusing on characteristics, treatments and outcomes, we performed a comprehensive individual patient data (IPD) meta-analysis of the cases reported in literature between 2003 and August 2024. PubMed and Web of Science were searched systematically for case reports using predefined search terms. The protocol was prospectively registered with the international prospective register of systematic reviews (PROSPERO CRD42022356345). 185 publications, consisting of case reports or small case series published between 2003 and 2024, were eligible. They reported on 202 patients. Median age at diagnosis was 54 years (range 13-86). The 5-year overall survival proportion was 77%. On univariable analysis, overall survival was significantly influenced by regional and distant metastases, histologic grading, receptor status, Ki-67 index and surgical intervention. We did not observe any significant outcome improvement over time. Only poorly differentiated neuroendocrine carcinoma and lack of surgery were found to be prognostic factors for poor overall survival in multivariable analysis. This rare subtype of breast cancer is associated with a poor prognosis with no meaningful treatment progress in the last 2 decades. The present study identified key prognostic factors. However, the available data are insufficient to determine the optimal treatment approach. Establishing uniform diagnostic criteria and consistently reporting cases is crucial to generate a larger pool of data, thereby advancing our understanding and management of this rare disease.</div></div>","PeriodicalId":10197,"journal":{"name":"Clinical breast cancer","volume":"26 2","pages":"Pages 146-160"},"PeriodicalIF":2.5,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145174063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Detection of the PBLN is critical for monitoring disease response and guiding subsequent treatment decisions. However, conventional sentinel lymph node biopsy (SLNB) techniques have shown unacceptable false negative rates. Recommendations for improvement suggest using dual tracers, removing more lymph nodes and implantable markers in the PBLN. This study evaluated the accuracy of PBLN identification using each of the 3 most common localization techniques: blue dye (lymphazurin), radioisotope (Technetium-99m sulfur colloid), and implanted fiducial marker (SAVI SCOUT).</div></div><div><h3>Methods</h3><div>Patients with PBLN marked with a SAVI SCOUT, with or without a metallic clip, and who received NAC were identified from our breast cancer surgery database. The accuracy of the 3 localizing techniques was evaluated.

A SAVI SCOUT was placed at the time of biopsy instead of a clip in 13 patients and identification of the PBLN was 100% for those patients. The mean number of lymph nodes removed with the SAVI SCOUT was 2.7, with radioisotope was 4.3 and with blue dye was 3.6 (<em>P</em> = .004). The mean number of SLN sampling events with the SAVI SCOUT was 1, with radioisotope was 2.0 (range: 0-6) and with blue dye was 1.8 (range: 0-5) (<em>P</em> &lt; .005).

The interaction between estrogen receptor (ER) and HER2 signaling pathways promotes tumor growth and therapeutic resistance, highlighting the need for tailored approaches. This review focuses on the clinical and molecular features of HR + /HER2 + metastatic BC, with an emphasis on recent data exploring the integration of CDK4/6 inhibitors (CDK4/6i) into anti-HER2 therapeutic strategies. Key findings from metastatic trials are summarized. HR + /HER2 + metastatic BC is characterized by a predominance of luminal molecular subtypes, associated with distinct patterns of metastatic spread and prolonged progression-free survival compared to nonluminal subtypes. Despite the efficacy of dual HER2 blockade, resistance remains a challenge, driven by crosstalk between ER and HER2 pathways. CDK4/6i disrupt the cell cycle at the G1/S checkpoint and have shown promise in overcoming resistance, inducing sustained senescence, and improving outcomes in luminal subtypes. Recent trials suggest that CDK4/6i may play a key role in maintenance therapy and chemotherapy-free regimens for selected patients with HR + /HER2 + metastatic BC. The integration of CDK4/6 inhibitors into anti-HER2 treatment strategies represents a promising approach to address the unique biology of HR + /HER2 + BC.
