Of the patients with recurrent MBC, less than half received a biopsy (49.5%) or biomarker reassessment (48.7%) to confirm the diagnosis of MBC. Patients treated at high- and medium-volume centers had higher rates of biopsy than low-volume clinics (51.9%, 54.3%, and 40.7%, respectively, <i>p</i> = 0.03).

Among the 677 patients with estrogen receptor (ER)+/HER2− MBC (de novo and recurrent), most received ET alone (69%), followed by CT (22%) and CDKi + ET (9%).

Patients meeting IHC 0 with membrane staining (HER2-ultralow) criteria may benefit from HER2-targeted therapies such as trastuzumab deruxtecan. This cohort study assessed the prevalence of HER2-ultralow expression by re-scoring HER2 IHC slides using Mayo Clinic electronic health record data. Three hundred patients with advanced breast cancer (Stages III-IV) and documented HER2 IHC 0 status (January 2017–March 2023) were identified. One slide per patient was digitized and independently re-scored by two Mayo Clinic pathologists following the 2023 ASCO-CAP guidelines, including tumor staining percentage to denote HER2-ultralow status. A sensitivity analysis was performed by a third independent pathologist. The re-scored patients had a mean age of 57.7 years (SD = 13.6). Most samples (95%, <i>n</i> = 285) remained scored IHC 0 by at least one pathologist; 60% of these met HER2-ultralow criteria per at least one pathologist. HER2-ultralow prevalence ranged from 43% to 45% per pathologist, with 57% overall interpathologist concordance. Samples with no observable staining comprised most of the concordant cases. Treatment patterns were similar between HER2-ultralow and no-staining groups; however, time to treatment failure (TTF) varied between groups across lines of therapy (LOT). In HR− positive cohorts, median TTF for LOT1 was 7.73 months in patients with HER2-ultralow versus 9.43 months with no observable IHC staining. In HR− negative cohorts, median TTF was 5.00 months for HER2-ultralow versus 3.17 months with no observable IHC staining. Similar TTF trends were observed in LOT2-LOT3. Approximately three in five samples originally classified as IHC 0 met HER2-ultralow criteria, suggesting many patients may benefit from HER2-directed therapy if reclassified. These findings highlight potential challenges of identifying HER2-ultralow expression and suggest the need for enhanced pathologist training, adherence to best practices, and integration of digital pathology and artificial intelligence solutions.</p><p><b>Trial Registration:</b> ClinicalTrials.gov_identifier: NCT03734029</p>","PeriodicalId":56326,"journal":{"name":"Breast Journal","volume":"2026 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2026-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/tbj/7212120","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148310808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
