Jayasekara H, et al. - Researchers sought to determine the long-term mortality following breast cancer diagnosis with respect to age at diagnosis, tumor estrogen receptor (ER) status, and the time already survived. Using the population-based Australian Breast Cancer Family Study which followed-up 1,196 women enrolled during 1992-99 when aged <60 years at diagnosis with a first primary invasive breast cancer, over-sampled for younger ages at diagnosis, for whom tumor pathology features and ER status were measured, they identified substantial and qualitative differences in the risk of death following a breast cancer diagnosis with diagnosis age, ER status and time survived. On an average longer life is expected for women who survive >7 years, those with ER-negative disease, and more so if these were younger at diagnosis.
