Phase 4 International study of the EORTC Breast Reconstruction (BRR) Questionnaire EORTC and NIHR CRN portfolio: 16639 Primary aim: To establish the psychometric validity of a European PROM (Patient Reported Outcome Measure) for women undergoing mastectomy and breast reconstruction (BRR) following breast cancer. Eligibility: Invasive breast cancer and Ductal Cancer in Situ (DCIS) requiring mastectomy Neo-adjuvant chemotherapy or endocrine treatment Recommended Post-Mastectomy Radiotherapy (PMRT) Completion mastectomy (within 6 months) for microscopic margin clearance Previous mastectomy (within 12 to 60 months) with no metastases Able and willing to complete the questionnaires No previous patient participation in earlier questionnaire development Implant only (with or without Acellular Dermal Matrix (ADM) assisted technique) BRR involving a dissected donor site (back, abdomen, buttock or thigh). Study Design: NRES Ethics approved (14/EM/0098) observational study comprising a prospective cohort (260 patients) and a crosssectional cohort (100 patients). The prospective cohort will complete a pre-operative or baseline questionnaire (before mastectomy and BRR) and one post-operative questionnaire at 6months after the final stage BRR. The cross-sectional cohort will complete the post-operative questionnaire at any time point in the preceding 12-60 months after ‘final’ BRR. This group will also complete a second questionnaire 3 weeks later. A debriefing questionnaire will be given to all women. Prospective Cohort: 260 patients Pre-operative assessment (Baseline): Completion of EORTC QLQ-C30, QLQ-BR23 and BRR15 questionnaire Post-operative assessment (6 months post BRR): Completion of EORTC QLQ-C30, QLQ-BR23 and BRR24 questionnaire + Debrief Q. Cross-sectional Cohort: 100 patients Time point 1: Completion of EORTC QLQ-C30, QLQ-BR23 and BRR24 questionnaire Time point 2 (test-retest reliability) - 3 weeks after time point 1: Completion of EORTC QLQ-C30, QLQ-BR23 and BRR24 questionnaire + Debrief Q. Patients will be given the “choice” to complete the questionnaires using the Computer-based Health Evaluation System (CHES), which allows web-based Patient Reported Outcomes (PRO) data collection versus the pen paper completion. CHES will also be used to record clinical data through Case Report Forms. Each centre will need to provide a touch screen tablet or PC for patients to use. 30 Collaborating centres: European (Austria: 2 centres, Italy: 2 centres, France: 2 centres, Sweden, Germany), UK (17 centres); International (Australia: 3 centres, New Zealand, Brazil).
