RAND Europe conducted a study on the societal impact of early breast cancer. This study was divided into three interconnected phases, which together aim to enrich the evidence base on the broader health, societal and economic impacts of treatment of early breast cancer, using a mixed methods approach. It highlights the available evidence and state of research on early breast cancer and considers the impact and 'cost' of disease progression for patients and their carers, as well as wider society. The first phase consisted of a mapping review on the published literature on the impacts of treatment of early breast cancer. The review revealed existing gaps in the evidence on the non-clinical impacts of treatment of early breast cancer to patients, carers or wider society. Studies of treatment effectiveness clearly dominate the literature and there is much less evidence on other types of outcomes extending beyond traditional treatment effectiveness evaluations. Yet understanding the wider impacts of cancer survivorship is important to better understand the impacts beyond treatment of breast cancer, and there is a need for more detailed analyses of these to inform better-informed decision making.

Key Findings

  • Most primary research that considers the impacts from treating early breast cancer report on either observational studies (48.0%) or randomised controlled trials (RCTs) (41.1%).
  • The most frequently reported outcomes across the pool of analysed primary papers are survival (55.0%) and recurrence (53.7%).
  • Chemotherapy, surgery and radiotherapy are the most common therapies (38.3%, 36.2% and 29.2% of all primary research studies respectively), followed by hormonal therapy (22.3%) and biological therapy (12.8%).
  • Only 15.6% of all primary papers in the sample analysed for the mapping review mentioned the country of focus for the studies they report on in the title and abstract, covering 33 countries, across diverse regions globally.
