The analysis aims to identify differences in tumor characteristics, treatment patterns, and outcomes of breast cancer in older women aged 70–79 versus those aged ≥80 years.
Population-based analysis of breast cancer patients at LMU Breast Center and Munich Red Cross Hospital
Comparison of clinical data from 2699 women aged 70–79 and ≥80 years
Evaluation of tumor biology and treatment approaches including surgery and systemic treatment.
Stable rates of breast-conserving surgery over time, with increased use of sentinel lymph node biopsy in both age groups.
Older patients (≥80) presented with larger tumors, received less systemic treatment despite similar hormone-receptor positivity.
Chemotherapy usage peaked in 2009, with a steady decline, while endocrine therapy increased; older patients less frequently received chemotherapy, often opting for endocrine therapy.
Patients aged ≥80 years exhibited higher rates of distant metastasis compared to those aged 70–79.
