Autologous fat grafting to the breast has been used as an adjunct to reconstructive breast surgery to contour deformities and improve shape and volume. Adipose-derived stem cells (ADSC) have been proposed as a supplement to the fat graft in an attempt to improve graft survival.Although adipose-derived stem cells could play a role in graft survival through adipogenesis, a complete understanding of the mechanisms of interactions among adipose stem cells and growth factors is lacking. Questions related to isolation, harvesting and purification of adipose-derived stem cells, their effect on cancer cell growth and their long term efficacy remain.
The use of adipose-derived stem cells in autologous fat grafting to the breast is considered investigational.

We develop Medical Policies to provide guidance to Members and Providers. This Medical Policy relates only to the services or supplies described in it. The existence of a Medical Policy is not an authorization, certification, explanation of benefits or a contract for the service (or supply) that is referenced in the Medical Policy. For a determination of the benefits that a Member is entitled to receive under his or her health plan, the Member's health plan must be reviewed. If there is a conflict between the Medical Policy and a health plan, the express terms of the health plan will govern.
The evidence for the use of adipose-derived stem cells in individuals who have breast cancer and are undergoing autologous fat grafting to the breast includes small single-arm studies, some of which are prospective. Limitations of the data are small numbers of participants, short-term follow-up and lack of understanding of the possible oncologic influence adipose-derived stem cells may have on the fat grafting procedure. The evidence is insufficient to determine the effects of this technology on health outcomes.
