Brief summary
The purpose of this study was to assess the amounts of particular immune cells in tissue around a specific type of breast cancer in patients whose cancer had returned. The results were compared to the amounts of these immune cells in tissue from patients with the same type of breast cancer whose cancer had not returned to evaluate whether these immune cells could help to predict which cancers were more likely to return.
Interventions
Data prospectively collected from January 2000 to June 2013 at a single centre at the Mount Hospital in Perth. Archival formalin-fixed, paraffin embedded samples one each of primary tumour and one of involved and uninvolved axillary nodes from 60 patients with luminal B early breast cancer who had experienced an invasive breast cancer event reviewed retrospectively. These were compared with Formalin-Fixed Paraffin-Embedded (FFPE) samples of one each from primary tumour and one from axillary nodes from a control group of 60 age and stage-matched patients treated in the same era who remained disease-free. Samples were examined for biomarkers identifying effector and suppressor immune cells and compared between the two groups. Participants were followed up per standard of care and data were collected as per standard of care as this study was a retrospective review of data collected propsectively as per standard of care (every 3 months for 2 years, 6 monthly for the following three years and then every year after that)
