Abstract

BACKGROUND:

Management of older women with breast cancer (BC) is challenging, as age-related comorbidities may limit treatment. We present 5-year follow-up data from women aged 70 years or older (70+), at the time of diagnosis of their BC, compared with younger women (<70 years).

METHODS:

Data is from an Australian cohort study of women with their first episode of invasive BC (Bupa study). Participants completed an enrollment questionnaire (EQ) within 12 months of diagnosis and annual follow-up questionnaires (FQ) for 5 years (FQ1-5). Data collected included details of the BC and its treatment. Psychological wellbeing was measured by the Psychological General Wellbeing Index (PGWB).

RESULTS:

At diagnosis, 274 (16%) women were aged 70+ and of them, 90% were aged 70-79 years. Compared with women aged <70 years, the women aged 70+ were less likely to have positive nodes, they were less likely to receive radiotherapy and chemotherapy and were more likely to have pre-existing cardiovascular morbidities. By FQ5 women aged 70+ were less likely to be taking oral adjuvant endocrine therapy (OAET) and were more likely to have died from causes other than BC. At FQ5, women 70+ reported less anxiety and better self-control.

CONCLUSIONS:

Women aged 70+, compared to <70 years, had less advanced disease, received radiation and chemotherapy less often, were more likely to have cardiovascular disease at the time of diagnosis, were less likely to be taking OAET at the 5-year assessment, and were more likely to die of causes other than breast cancer.
