Clinical Trial Summary

A multicentre prospective cohort study will monitor the efficacy and safety of Autologous Fat Transfer (AFT) with pre-expansion. AFT will be evaluated in terms of quality of life, aesthetic result, complications, oncological safety and cost-effectiveness. It follows the BREAST trial, the randomised controlled trial comparing AFT with implant-based reconstruction. In this study, patients all receive AFT.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Breast-related Quality of life	Measured by the BREAST-Q questionnaire (quality of life subdivision)	2 years
Secondary	Aesthetic result	The overall aesthetic result will be measured using 3D-photographs which will be assessed by a panel of independent plastisch surgeons, ex-breast cancer patients and healthy volunteers. In addition, the volume, shape and symmetry will be assessed by the patient using the BREAST-Q questionnaire (satisfaction with breasts subdivisions).	2 years
Secondary	Complications	Measurement of short-term als well as mid-term complications associated with procedures as well as (serious) adverse events.	2 years
Secondary	Oncological safety	Oncological follow-up will comply to the guidelines for breast cancer and will take place by a yearly consult with the oncological surgeon (including physical examination and mammography/ultrasound/MRI) for 5 years postoperatively. All (loco)regional and distant recurrences will be recorded.	5 years
Secondary	Cost-effectiveness	Cost-effectiveness analysis to determine the intramural and socio-economic costs associated with the breast reconstruction treatment.	2 years
