title: Breast cancer in elderly women: presentation, survival, and treatment options.
abstract: Recent data suggest that breast cancer in elderly women does not present as more advanced disease, nor is survival significantly inferior to that in younger women. Unfortunately, until recently, older women have been excluded from clinical trials that have determined survival benefit in both screening and treatment modalities. Unless co-morbid conditions adversely affect one's life expectancy or tolerance to therapy, older women should be treated with standard surgical procedures (including breast conservation, if so desired) for early-stage disease, as outcome is comparable to that in younger patients. Adjuvant tamoxifen therapy has proven survival benefit in women over 70 years of age with estrogen receptor-positive tumors and should be considered in all women with tumors greater than 1 cm in size. Older women may experience more chemotherapy-related toxicities. However, for those with a significant risk of recurrence due to tumor size or lymph node status, chemotherapy can be safely administered when factors such as age-related decline in creatinine clearance and co-morbid conditions are considered. Hormonal therapy (tamoxifen) is usually the first-line treatment option over chemotherapy for metastatic disease in the elderly unless the patient has an estrogen receptor-negative tumor, visceral-dominant disease, or significant disease-related symptoms. In the latter settings, chemotherapy can provide improved or more rapid response proportions but does not affect long-term survival.
