Trastuzumab as a first HER2-targeted therapy for the treatment of HER2-positive breast cancer patients was introduced in 1998. Although trastuzumab has opened a new avenue to treat patients with HER2-positive breast cancer and other types of cancer, some patients are not responsive or become resistant to this treatment. So far, several mechanisms have been suggested for the mode of action of trastuzumab; however, the findings regarding these mechanisms are controversial. In this review, we aimed to provide a detailed insight into the various mechanisms of action of trastuzumab.

This study aims to explore the risk factors associated with poor survival outcomes in geriatric female patients with breast cancer. This study utilized data from the METABRIC database to evaluate the risk factors associated with poor survival outcomes among geriatric breast cancer patients. A total of 2909 female patients, 766 of whom were geriatric, were included in the study.

Article Synopsis
  • The study investigates the role of ERBB3 expression in HER2-positive breast cancer and its potential impact on treatment resistance.
  • Through various bioinformatics techniques and machine learning algorithms, the researchers identified three key genes—PBX1, IGHM, and CXCL13—that are linked to ERBB3 expression and can serve as prognostic markers.
  • Findings suggest that these genes may influence breast cancer cell behavior and prognosis, emphasizing their significance in understanding HER2-positive breast cancer treatment outcomes.

Apatinib and trastuzumab-based chemotherapy for heavily treated primary trastuzumab-resistant metastatic breast cancer.

J Cancer Res Ther

December 2024

Department of Medical Oncology, National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital and Shenzhen Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Shenzhen, People's Republic of China.

Article Synopsis
  • The study examines the effects of a combination therapy (apatinib and trastuzumab-based chemotherapy) on patients with primary trastuzumab resistance (PTR) in HER2-positive breast cancer.
  • A total of 20 PTR patients were treated, showing a clinical benefit rate of 55%, though no complete responses were observed, and median progression-free survival was 5.7 months.
  • While the treatment had manageable side effects, further research is recommended to better identify which PTR patients could potentially benefit from this therapy.

Therapeutic decision-making for older patients with human epidermal growth factor receptor 2 (HER2)-positive breast cancer highlights the importance of a comprehensive geriatric assessment (CGA). This assessment considers the functional status, comorbidities, and relevant conditions of the patient, and allows for an estimation of life expectancy, but it does not facilitate individualized treatment plans. There are also other challenges to consider related to the cardiac toxicity of the treatments and the under-representation of older patients in clinical trials.

Sushi domain-containing protein 2 (SUSD2), a transmembrane protein containing a sushi motif, has been reported to have tumor-promoting functions in various types of cancer, including breast cancer. However, the regulatory mechanism of SUSD2 and its function in HER2-positive (HER2+) breast cancer have not been fully identified as yet. In this study, we explored the potential of targeting SUSD2 to overcome trastuzumab (TRZ) resistance in HER2+ breast cancer.
