Oncoplastic Breast Consortium consensus conference on nipple-sparing mastectomy.
Purpose
Indications for nipple-sparing mastectomy (NSM) have broadened to include the risk reducing setting and locally advanced tumors, which resulted in a dramatic increase in the use of NSM. The Oncoplastic Breast Consortium consensus conference on NSM and immediate reconstruction was held to address a variety of questions in clinical practice and research based on published evidence and expert panel opinion.
Methods
The panel consisted of 44 breast surgeons from 14 countries across four continents with a background in gynecology, general or reconstructive surgery and a practice dedicated to breast cancer, as well as a patient advocate. Panelists presented evidence summaries relating to each topic for debate during the in-person consensus conference. The iterative
process in question development, voting, and wording of the recommendations followed the modified Delphi methodology.
Results
Consensus recommendations were reached in 35, majority recommendations in 24, and no recommendations in the remaining 12 questions. The panel acknowledged the need for standardization of various aspects of NSM and immediate reconstruction. It endorsed several oncological contraindications to the preservation of the skin and nipple. Furthermore, it recommended inclusion of patients in prospective registries and routine assessment of patient-reported outcomes. Considerable heterogeneity in breast reconstruction practice became obvious during the conference.
Conclusions
In case of conflicting or missing evidence to guide treatment, the consensus conference revealed substantial disagreement in expert panel opinion, which, among others, supports the need for a randomized trial to evaluate the safest
and most efficacious reconstruction techniques
Endoscopic Reconstruction of Partial Mastectomy Defects Using a Latissimus Dorsi Muscle Flap Without Causing Scars on the Back
Endoscopic reconstruction of partial mastectomy defects using latissimus dorsi muscle flap without causing scars on the back
Background: Results obtained with breast-conserving therapy are not always satisfactory. Reconstruction with a pure latissimus dorsi muscle flap is a useful option. The techniques described for endoscopic dissection of the flap create several scars on the back. As a result, they do not improve on the open approach, which causes a horizontal scar at the level of the bra strap. The authors' technique avoids all scars on the back using a single incision in the highest folds of the axilla, which also is used for the sentinel node biopsy or lymphadectomy and quadrantectomy. Methods: The study was performed with 23 patients. The tumor was extracted via a clockwise downward periareolar incision and via another incision in a fold of the axilla. Through this axillary incision, the sentinel lymph node biopsy or lymphadectomy was performed, and the external part of the latissimus dorsi muscle was harvested endoscopically for the reconstruction. Results: Both the medical team and the patients reported high satisfaction with the aesthetic and functional results due to the preservation of the breast shape and the absence of any scarring on the back. Conclusion: Endoscopy-assisted techniques make either three small scars on the back or one long scar, with the muscle sectioned distally, or a vertical incision in the midaxillary line, which may form a hypertrophic or keloid scar. The authors' approach avoids the creation of these scars on the back because the endoscopy and the distal sectioning of the muscle flap are performed through the single axillary incision.

Platelet-rich plasma mixed-fat grafting: a reasonable prosurvival strategy for fat grafts?
Background: One of the most interesting developments in practical applications of fat grafting in recent years is the use of prosurvival strategies to improve maintenance of volume. Platelet-rich plasma (PRP) plays a decisive role in the repair and regeneration of different tissues via the activation and secretion of a great variety of growth factors and other cytokines stored in the alpha-granules of the platelets. This review aimed to assess the efficacy of PRP mixed-fat grafting as a prosurvival strategy for fat grafts.
Methods: Online searches of the Cochrane Library and MEDLINE until January 2014 were conducted. The review included studies with at least one clinical end point in which the effect of PRP on the absorption and viability of the fat graft could be assessed.
Results: The review comprised 6 preclinical studies with a control group and 9 clinical studies of humans. It also included comparative studies performed with other prosurvival strategies for fat grafts, such as combination with the stromal vascular fraction and second-generation PRP, also called “platelet-rich fibrin.” The results indicate that PRP may have a dose-dependent positive effect on fat grafts and suggest low complication rates.
Conclusions: The development of new growth factor delivery systems or cell therapies to enrich fat grafts is an area that merits further research
