The main goal of the trial was to analyse the value of radiotherapy after breast conserving surgery for patients with breast cancer, and to find groups of patients where the treatment could be omitted.
The trial recruited patients between 1991-1996, and the primary outcome in terms of recurrences has been updated through the years since then. Tumour material has been collected in order to study prognostic and predictive factors for breast cancer patients that are treated today. Late side effects of the treatment are studied.
