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
Patients diagnosed with local +/- regional recurrence (LRR) with high-risk tumor characteristics and previously treated with postoperative local +/- regional irradiation for primary breast cancer/previous recurrence with an indication for salvage mastectomy with/without postoperative re-irradiation (+/-hyperthermia).
Patients 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 therapy (NST) is allowed.
Use of (FES/FDG-)PET-CT in 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) are allowed.
