Chemotherapy in the elderly with breast cancer.

The number of elderly women diagnosed with breast cancer by 2025, will increase by 72%. These elderly women do not yet participate in most screening programmes. One notes more favourable biological characteristics of the tumour, including more expression of steroid receptors (oestrogen receptor, progesterone receptor), low proliferative rate, good differentiation, normal p53 and low expression of epidermal growth factor. Elderly breast cancer patients are frequently treated with breast conservation, omitting axillary dissection, radiation therapy and chemotherapy. There is a paucity of data to substantiate that such an approach is better than a more radical one. The efficacy of chemotherapy and guidelines for its use vary by tumour stage and patient age. Drugs like modified anthracyclines, vinorelbine, the taxanes and capecitabine may be changing the paradigm of combination therapy superiority.
