Immediate Tissue Expander and Lipofilling After Mastectomy for Breast Cancer Recurrence Following Lumpectomy and Irradiation: Retrospective Multicentric Clinical Trial
Immediate Tissue Expander and Lipofilling After Mastectomy for Breast Cancer Recurrence Following Lumpectomy and Irradiation: Retrospective Multicentric Clinical Trial
Higher rates of complications and poorer cosmetic outcomes have been reported after salvage mastectomy and implant-based versus autologous reconstruction in patients previously exposed to radiation therapy (i) on the breast as adjuvant treatment after breast conserving surgery (BCS) or (ii) on thoracic wall for Hodgkin Lymphoma (HL). Nevertheless, selected patients with favourable preoperative soft-tissue assessment may benefit from alloplastic reconstruction and fat grafting that has been suggested as an effective technique to promote the regeneration of irradiated tissues.
The aims of this study are to assess:
National Comprehensive Cancer Network guidelines recommend autologous reconstruction as the preferred breast reconstruction after mastectomy in previously irradiated patients because of higher complication rates and worse aesthetic outcomes as compared to immediate breast implant reconstruction. In fact, unacceptable rates of complications (60-70%) have been reported by first experiences. Instead, autologous reconstruction showed lower complication rates as compared to implant-based breast reconstruction (25.5% vs 50.9%). However, it may not be indicated in patients with previous surgery at the donor site or in case of other contraindications, requires longer surgical time and is at risk of donor-site morbidity and loss of sensation.
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.
