Breast cancer-specific mortality is static in older women despite having fallen in younger age groups, possibly due to lack of screening and differences in treatment. This study compared stage and treatment between two cohorts of postmenopausal women (55-69 vs >70 years) in a single cancer network over 6 months. A total of 378 patients were studied (>70: N=167, 55-69 years: N=210). Older women presented with more advanced disease (>70: metastatic/locally advanced 12%, 55-69 years: 3%, P<0.01). Those with operable cancer had a worse prognosis (Nottingham Prognostic Index (NPI) >70: median NPI 4.4, 55-69 years: 4.25, P<0.03). These stage differences were partially explained by higher screening rates in the younger cohort. Primary endocrine therapy was used in 42% of older patients compared with 3% in the younger group (P<0.001). Older women with cancers suitable for breast conservation were more likely to choose mastectomy (>70: 57.5% mastectomy rate vs 55-69 years: 20.6%, P<0.01). Nodal surgery was less frequent in older patients (>70: 6.7% no nodal surgery, 55-69 years: 0.5%, P<0.01) and was more likely to be inadequate (>70: 10.7% <4 nodes excised, 55-69 years: 3.4%, P<0.02). In summary, older women presented with more advanced breast cancer, than younger postmenopausal women and were treated less comprehensively.
