HER2-positive gastric cancer (GC), a unique molecular subtype, has garnered significant interest in recent years. Here, we review clinical trial data on advanced HER2-positive GC from the past 15 years. Trastuzumab plus standard chemotherapy remain the first-line treatment. The initial survival benefits conferred by immune checkpoint inhibitors plus trastuzumab and standard chemotherapy are encouraging. The combination of ramucirumab and mono-chemotherapy, as well as the antibody conjugated drug trastuzumab deruxtecan, is the recommended second-line regimen. Treatment with immune checkpoint inhibitors plus ramucirumab and mono-chemotherapy shows promise. Despite the limited treatment options for third line and beyond, development of novel therapeutic strategies is expected. Although clinical cure of advanced HER2-positive GC is unlikely, current clinical studies offer valuable insight into regimens that prolong survival.

Gastric cancer is a common malignant tumor with high incidence and mortality. The overexpression of Human epidermal growth factor receptor 2 (HER2) is associated with increased metastatic potential and poor clinical outcome in gastric cancer. Despite the proven clinical response rates of approved HER2-targeted therapies, including Trastuzumab combined with chemotherapy, their limited long-term clinical benefits and inevitable disease progression still pose significant challenges to the clinical treatment of gastric cancer.

Current therapies suppress growth-promoting biochemical signals, ablate cells expressing tumor-associated antigens, or promote adaptive immunity to tumor neoantigens. However, these approaches are limited by toxicity to normal cells using the same signaling pathways or expressing the same antigens, or by the low frequency of neoantigens in most carcinomas.

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.

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.
