A relatively high prevalence of BM is seen in patients with germline BRCA1/2 mutations. Some patients with MBC have somatic BRCA1/2 mutations but the prevalence of BM in this setting is not known.</p><p><strong>Methods: </strong>Here, we evaluated the prevalence and clinical and genomic characteristics of BM in patients with MBC with somatic BRCA1/2 mutations in cell-free DNA (cfDNA) using the Guardant360 assay. Clinical and genomic features of patients with somatic BRCA1/2 mutations and brain metastases, and those without brain metastases were compared using a Chi-squared test for categorical variables and Wilcoxon rank-sum test for continuous variables.</p><p><strong>Results: </strong>Of 36 patients with MBC and somatic BRCA1/2 mutations, 9 (25%) developed BM. The median time to development of BM was 6.7 months after somatic BRCA detection by cfDNA testing. Among patients with BM, somatic BRCA mutations were commonly BRCA1, clonal, and present at a higher mutant allelic fraction. The coexisting genomic landscape in patients with BM commonly included PIK3CA, TP53, MYC, EGFR, CCNE1, and KIT mutations.</p><p><strong>Conclusion: </strong>A relatively high prevalence of BM in patients with MBC harboring cfDNA somatic BRCA1/2 mutations was observed. CfDNA somatic BRCA1/2 mutations may help identify patients with MBC at risk for BM. To our knowledge, this is the first report linking cfDNA somatic BRCA mutations with BM, and requires further investigation in additional datasets and studies.</p>","PeriodicalId":9133,"journal":{"name":"Breast Cancer Research and Treatment","volume":" ","pages":"107-112"},"PeriodicalIF":3.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143976232","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}

The optimal timing of chemotherapy-neoadjuvant (NACT) versus adjuvant (ACT)-remains controversial. This study assessed real-world outcomes in non-metastatic TNBC patients according to chemotherapy timing.</p><p><strong>Methods: </strong>This retrospective study (2008-2023) evaluated the impact of chemotherapy timing on overall survival (OS) and event-free survival (EFS) in a cohort of 711 patients. Propensity score (PS) matching with preoperative variables was used to adjust for baseline imbalances, and Cox regression models were applied to account for treatment-related variables.</p><p><strong>Results: </strong>NACT was administered to 525 patients (73.8%), with a 37.3% pathological complete response (pCR) rate. PS matching yielded 177 patient pairs; tumor stage, age and histologic grade remained unbalanced. In the unadjusted analysis, NACT was associated with worse OS (HR 1.56, 95% CI1.08-2.25, p = 0.018). However, multivariate analysis adjusting for unmatched and postoperative variables showed a potential benefit of NACT for OS (HR 0.53, 95% CI 0.07-4.13, p = 0.545) and EFS (HR 0.94, 95% CI 0.21-4.17, p = 0.932). Tumor stage acted as an effect modifier, and stratified analyses revealed that NACT was superior to ACT in patients with advanced-stage disease who achieved pCR (HR 0.22, 95% CI 0.07-0.7, p < 0.010).</p><p><strong>Conclusions: </strong>In our TNBC cohort, chemotherapy timing significantly influenced OS and EFS, particularly in relation to initial tumor stage and pCR status. NACT was more beneficial than ACT in patients with advanced disease who achieve pCR, underscoring its role in both prognostic stratification and therapeutic decision-making.</p>","PeriodicalId":9133,"journal":{"name":"Breast Cancer Research and Treatment","volume":" ","pages":"225-236"},"PeriodicalIF":3.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144118793","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}
