  • histology of the cancer and patients' characteristics including: type, size and grade of the tumour; side of the body affected; lymph node status; oestrogen receptor status; progesterone receptor status; human epidermal growth factor receptor 2 status; and age of the patient

  • local recurrence

  • treatment after local recurrence

  • metastatic disease

  • disease-free survival

  • overall survival

  • adverse effects of treatment

  • health-related quality of life (including EQ‑5D).
