The Netherlands • Increase incidence breast cancer 2005-2025 18% • 40-50% of these patients are 65 years and older • 50-75% has comorbidity of any kind • No internationally agreed recommendations • Lack of clinical trial data • Uncertainty treatment toxicity and benefits • Interaction between therapy and comorbidity • Competing risks of death • New pathological and molecular variables associated with outcome and response to therapy • Lack of assessment tools to identify at-risk and frail elders in oncology FOCUS
Giordano et al. JCO2005;4:783-91 Several cohort studies • Less aggressive therapy (corrected stage) • Strongly decreased survival (not only explained by therapy) • Stage at diagnosis higher • Tumor biology: increased hormone receptor positive, less Her2/neu overexpression, lower grades, lower proliferative indices • Life expectancy is central issue • However • Variability within age group is large (individualized treatment) • Comorbidity • Risks / benefits treatment FOCUS
In conclusion • Increasing incidence of breast cancer in elderly However: • Limited data • No guidelines for individualized treatment Female breast cancer in the elderly; Optimizing clinical guidelines using clinico-pathological and molecular data FOCUS FOCUS

Data from clinical trials EORTC 10902 Preoperative chemotherapy EORTC 10801 BCT vs Mastectomy Pooled dataset n=5500 (>65 years) EORTC 10854 Perioperative chemotherapy EORTC 22881 TEAM data FOCUS
Trial data • Comparison of characteristics between the young and the elderly patients Selection of the elderly 2. Multivariate analysis Survival (OS, DSS, DFS) 3. Risk factors for the elderly - Morbidity - Frequency of Adverse Events - Treatment withdrawal 4. Age stratified analysis (65-74; 75-84 and 85 and older) within the elderly patients (age-dependent prediction model) FOCUS
Three parts FOCUS
Gene expression analyis • Recent studies no inclusion of elderly • Relevance of the signatures in elderly patients are unknown • Which factors are significantly different between young and elderly patients • Are there different activated pathways in young vs. elderly breast cancer patients • Validate existing and/or find new prognostic/predictive factors for elderly breast cancer patients FOCUS
Central dogma of molecular biology • DNA in nucleus • Genes and non-coding regions • Gene: Introns and exons • Transcriptie DNA RNA Poly A tail, cap and splicing mRNA • mRNA translated into protein in cytoplasm FOCUS
Methods DNA SNP array • Infinium SNP array Illumina mRNA Expression array • Human WG6 expression array Illumina Protein Immunohistochemical staining on Tissue Micro Array (TMA) FOCUS
Three parts Prospective study FOCUS
Prospective study Combination of all data * Molecular data * Trial data * Data from cohorts Risk model - Recurrent disease - (Breast cancer related) death - Adverse events - Patient and tumor characteristics Evidence based, high quality care Tailored treatment guidelines FOCUS
