Endpoints

​​Primary endpoint:  Patient-reported toxicity according to PRO-CTCAE after a median follow-up of five years after diagnosis of (subsequent) LRR disease.                                                                                        

Secondary endpoints:

  • Quality of Life (EORTC-C30 and –BR45). LRR-free, distant metastasis-free, breast-cancer event-free and overall survival at 2 and 5 years after diagnosis of LRR disease.
  • Referral patterns (per institute, professional, patient-related factors including performance status, and travel distance). ​ 

Eligibility Criteria

  • Diagnosed with local +/- regional recurrence (LRR) (i.e. true recurrence or second primary) with intermediate or high-risk tumor characteristics* and previously treated with breast-conserving therapy (i.e. breast-conserving surgery and radiotherapy) +/- regional irradiation for primary breast cancer/previous recurrence with an indication for salvage mastectomy with/without postoperative re-irradiation (+/-hyperthermia)** re-irradiation = overlap of re-irradiated volume with previous irradiated volume
  • Diagnosed with a chest wall recurrence and treated with local excision with/without NAST and postoperative re-irradiation with/without hyperthermia. In patients with a clinical/radiological complete response after neoadjuvant systemic treatment, NO surgery and re-irradiation (+/- hyperthermia) (since surgery is not possible in this group)
  • (Neo-)adjuvant systemic (NAST) treatment is allowed
  • Use of PET(FES/FDG)-CT for staging of nodal and disseminated disease
  • Oligometastases in lymph nodes in the mediastinum, neck, contralateral axillary/supraclavicular region (up to a maximal number of five) is allowed

 

* Definition of intermediate and high-risk tumor characteristics are:
• (Focal) irradical resection
• All clinical and pathological stages except for low-risk LRR:
– rcT1-2N0
– r(y)pT1-2N0

** according to local clinical practice and/or shared decision making process
