Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The aims of this study are to assess:
1. the feasibility of implant-based breast reconstruction and fat grafting after mastectomy (simple mastectomy, nipple-sparing and skin-sparing mastectomy)
2. oncological safety of implant-based breast reconstruction and fat grafting.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
On the other hand, fat grafting improves softness of tissues and scars, releasing their rigidity and for these effects it has been studied for effectively promoting the regeneration of irradiated tissues, enlarging the envelope thickness for safety reasons, optimizing cosmetic outcomes and ultimately increasing patient comfort and quality of life.
Therefore, a surgical technique combining implant-based breast reconstruction after mastectomy and fat grafting may favor alloplastic reconstruction in selected patients.
The investigators enroll patients candidate to mastectomy and breast reconstruction who had received prior adjuvant radiation therapy after breast conserving surgery (BCS) or radiation therapy for the treatment of Hodgkin Lymphoma (HL).
Aims of the study are to investigate (i) the feasibility of implant-based breast reconstruction and fat grafting after mastectomy (simple mastectomy, nipple-sparing and skin-sparing mastectomy); (ii) the oncological safety of implant-based breast reconstruction and fat grafting.

Immediate tissue expander and fat grafting after mastectomy
Patients underwent simple mastectomy, skin-sparing or nipple-sparing mastectomy and implant-based, two-stage breast reconstruction: contextual mastectomy and expander positioning were performed during first stage (stage I) while substitution of the expander with definitive implant occurred during second stage (stage II). Fat grafting with regenerative intent was performed during stage I or between stage I and II. Adipose tissue was harvested from the abdomen, flanks, trochanter regions, inner thigh and medial aspect of knees. Fat was injected in the subfascial plane of the pectoralis major muscle with blunt cannula in order to avoid thrombo-embolic risks. At least six months after stage I patients underwent expander substitution with definitive implant and contralateral mammoplasty when required. In case of complications that required removal of the implant, autologous reconstruction was performed.
Immediate tissue expander and lipofilling after mastectomy
Implant-based breast reconstruction and fat grafting after salvage or prophylactic mastectomy in patients previously exposed to radiation therapy on the breast as adjuvant treatment after breast conserving surgery (BCS) or on thoracic wall for Hodgkin Lymphoma (HL).
