This study aimed to assess the treatment response of HLX02-based neoadjuvant therapy in HER2-positive BC, with a focus on HR-positive versus HR-negative subgroups. Additionally, we investigated the potential role of a CDK4/6 inhibitor in combination with anti-HER2 therapy.</p>\u0000 <p><b>Methods:</b> This retrospective study included HER2-positive BC patients who received HLX02-based neoadjuvant therapy followed by curative surgery at Anhui Provincial Cancer Hospital between March 2021 and August 2023. Pathological complete response (pCR) rates were analyzed, and subgroup analyses evaluated predictors of pCR. In vitro experiments using BT-474 and MCF-7 cell lines assessed the effects of combining CDK4/6 inhibitors with anti-HER2 therapy on cell viability and apoptosis.</p>\u0000 <p><b>Results:</b> The study included 67 patients with a median age of 53 years. The overall pCR rate was 53.73%, with higher pCR rates observed in HR-negative patients compared to HR-positive patients (63.89% vs. 41.94%). Dual HER2 blockade with HLX02 and pertuzumab was associated with a numerically improved pCR rate (62.16%). ER expression significantly increased post-treatment, potentially indicating treatment resistance mechanisms. In vitro, the combination of CDK4/6 inhibitors with anti-HER2 therapy significantly reduced cell viability and promoted apoptosis in HR-positive, HER2-positive cell lines.</p>\u0000 <p><b>Conclusion:</b> HLX02 demonstrates real-world efficacy as part of neoadjuvant therapy for HER2-positive BC, especially in HR-negative patients. The lower pCR rate in HR-positive patients highlights the need for additional strategies. Combining CDK4/6 inhibitors with anti-HER2 therapy presents a promising approach for HR-positive HER2-positive patients, warranting further clinical validation.</p>\u0000 </div>","PeriodicalId":56326,"journal":{"name":"Breast Journal","volume":"2025 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/tbj/1653319","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144598512","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}

Linear/cystic hypoechoic areas could be detected within the lesion in 12 cases (41.4%), and in 17 cases, the lesions had extensive conventional ultrasound findings with no significant features. The ultrasound-measured lesion diameters were smaller than those measured in surgically resected lesions, and the statistical difference was highly significant (<i>p</i> &lt; 0.01). Fifteen cases underwent CEUS examination, with 7 lesions (46.7%) demonstrating uniform enhancement and 8 lesions (53.3%) exhibiting nonuniform enhancement.

The areas of patchy perfusion defects corresponded to the linear/cystic hypoechoic regions observed in the conventional sonographic images of the lesions.
