Breast cancer treatment must nowadays optimize cosmetic results. This can be accomplished in selected cases by means of a single-stage operation that the authors call "skin-reducing mastectomy." The final scars imitate those of cosmetic surgery. Careful patient selection and improvement in the learning curve may reduce the complication rate.

In this study we performed 77 procedures on 65 patients fulfilling the oncological criteria for skin-sparing mastectomy and presenting with large or medium size breasts. All the operations were performed as a single-stage procedure with an anatomical prosthesis allocated into a compound pouch, made up of the pectoralis major, serratus anterior fascia, and a lower dermal adipose flap. The medium size of the anatomical implants employed was 444.3 cc. The implant removal rate was 14.2%. At a median follow-up of 36 months we reported a 0.5% local recurrence rate per year. The overall specific survival rate was 98.2%. This study confirms the safety and effectiveness of this technical variation of skin and nipple-sparing mastectomies. All breast, irrespective of mammary shape and size, can be reconstructed with medium size implants and, if required, contralateral adjustments. The overall complication rate is in keeping with previous studies.

Introduction: During the last few years it has been shown that an anaplastic T cell lymphoma can develop as a rare and late sequelae of implant-based breast reconstruction. This malignancy was recognized in the 2017 by WHO and named breast implant associated anaplastic large T cell lymphoma (BIA-ALCL). BIA-ALCL usually presents as abundant effusion around the implant, thus, in addition to cytology smears, its diagnosis also requires immunohistochemistry, T cells clonality and cytometry. Due to the increasing attention of clinicians, it is likely that the number of the BIA-ALCL suspected cases will grow in the future, implying the necessity of a reliable and cost-effective diagnostic procedure. Methods: To achieve this goal, we retrospectively analyzed the results of laboratory investigations performed at our Institute (Fondazione IRCCS Istituto Nazionale dei Tumori Milan, Italy) on 44 effusions obtained from 31 women suspected for BIA-ALCL. Results: Through cytology, eight out of 44 effusions showed the presence of BIA-ALCL cells. Lymphoma cells were than confirmed in seven samples by immunohistochemistry and/or T cell clonality and/or cytometry. Overall, cytology showed 100% sensitivity, 97% specificity and positive and negative predictive values of 87.5% and 100% respectively. Further analyses were particularly useful in effusions showing small percentages of BIA-ALCL cells. Moreover, an extended cytometric profile that can be applied when fast confirmation of the cytologic result is required was also identified. Conclusions: Our results evidenced a central role of cytopathology in the management of BIA-ALCL suspected effusions and suggested that further laboratory investigations might be applied only in cases showing atypical/activated lymphoid cells through cytology.

The Authors present a novel technique of immediate breast reconstruction with definite implants after mastectomy conserving the nipple-areola complex and, less frequently, in skin-sparing mastectomy. The increase of indications for both oncologic and prophylactic nipple-sparing mastectomy has induced the research for a single-stage technique that could replace the two-stage reconstruction with expanders and/or autogenous reconstructions with flaps. The new techniques introduce modifications of the pocket coverage for the implants occurring in two ways: i) autologous adaptation of muscle-fascia-fat-skin layers, ii) application of alloplastic materials as the meshes. A series of 124 immediate reconstructions were performed from 2008 to 2011 using a continuous composite pocket made of pectoralis maior and serratus anterior muscle above, and skin-fat flap below. The innovation is represented by an extended electrosurgical scoring of the lower pole of the mammary pocket at two levels. The first is the deep-fascia and muscle layer; the second is the superfiacial fascial system. This operative technique represents an advancement of a prior procedure described by the Authors in 1998. This preliminary study would primarily describe the technique step by step. Discussion debates about alternative techniques in terms of either surgical details of technique or cosmetic results are still to be reached.

This report concerns only a few potential patients, but supports a trend that surgeons should consider. An elective indication for transabdominal breast augmentation can be represented even by those few patients who are candidates for TRAM flap reconstruction, who are agreeable to a small augmentation in the absence of a scar on their healthy breast, and whose reconstructed breast is larger and more prominent at the central part of the mound than on the contralateral side.
