Objectives: Objectives: The aim of this study was to evaluate the safety and efficacy of a study group (SG) regarding the use of FG-e-ASCs in breast augmentation for aesthetic improvement, comparing the results with a control group (CG) and at the same time the safety and efficacy of a study group (SG-1) regarding the use of FG-e-ASCs in breast reconstruction, comparing the results with a control group (CG-1).
Introduction: Fat graft enhanced with adipose-derived stem cells (FG-e-ASCs) has been utilized in outcomes of radiotherapy after mastectomy, breast soft tissue defects, ulcers, and loss of substance. The authors present their experience using FG-e-ASCs in breast augmentation and breast reconstruction.
Materials / method: A total of 46 patients affected by breast hypoplasia (SG) were treated with FG-e-ASCs, comparing results with those of a CG (n = 30) treated with fat graft not enhanced (FG-ne-ASCs). 121 patients (SG-1) that were affected by the outcomes of breast oncoplastic surgery were treated with FG-e-ASCs, comparing the results with the CG-1(n = 50) treated with FG-ne-ASCs. The preoperative evaluation included a complete clinical evaluation, a photographic assessment, MRI, US, and mammography. Postoperative follow-up took place at 1, 3, 7, 12, 24, and 48 weeks, and then annually.
Results: SG patients treated with FG-e-ASCs showed 58% maintenance of the volume after 3 years compared with the patients of the CG treated with FG-ne-ASCs, who showed 29% maintenance. In 67.4% (n = 31) of breast augmentation treated with FG-e-ASCs, we observed an increase of 10.3 mm in the 3D volume after 36 months, which was observed in only 20.0% (n = 6) of patients in the CG.
In 72.8% (SG-1 n = 88) of breast reconstruction treated with FG-e-ASCs, we observed an increase of 12.8 mm in the 3D volume after 12 weeks, which was only observed in 27,3% (n = 33) of patients in the CG-1.
Conclusion: The use of FG-e-ASCs was safe and effective in this series of cases performed.
