Abstract
Here, we describe a step-by-step novel level I oncoplastic technique and present the aesthetic results of 58 breast cancer patients who underwent the spoon-shape technique for primary tumor resection. The Paris Breast Center’s 5-point scale was used to evaluate the aesthetic outcomes. The median age of the participants was 52 years old. The average size of the resected tumor was 22.1 mm; two intraoperative re-excisions were required due to positive margins. Postoperative localized seroma was observed in four patients, and one patient presented signs of wound infection. Skin flap necrosis and fat liquefaction were not observed. The average aesthetic score was 4.86. None of the patients presented cancer recurrence in the following two years. The spoon-shape technique showed good aesthetic results because it provided the surgeons an adequate amount of surrounding tissue from which to reshape the breast after tumor removal. We encourage surgeons to apply this approach in early-stage breast cancer, regardless of the quadrant where the tumor is located.

[PMID: 34894122 PMCID: PMC8665419 DOI: 10.1093/bjsopen/zrab126] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2021] [Accepted: 11/05/2021] [Indexed: 11/12/2022] Open
Abstract
BACKGROUND Therapeutic mammaplasty (TM) is an oncological procedure which combines tumour resection with breast reduction and mastopexy techniques. Previous systematic reviews have demonstrated the oncological safety of TM but reporting of critically important outcomes, such as quality of life, aesthetic and functional outcomes, are limited, piecemeal or inconsistent. This systematic review aimed to identify all outcomes reported in clinical studies of TM to facilitate development of a core outcome set. METHODS Medline, EMBASE, CINAHL and Web of Science were searched from inception to 5 August 2020. Included studies reported clinical outcomes following TM for adult women. Two authors screened articles independently for eligibility. Data were extracted regarding the outcome definition and classification type (for example, oncological, quality of life, etc.), time of outcome reporting and measurement tools. RESULTS Of 5709 de-duplicated records, 148 were included in the narrative synthesis. The majority of studies (n = 102, 68.9 per cent) reported measures of survival and/or recurrence; approximately three-quarters (n = 75, 73.5 per cent) had less than 5 years follow-up. Aesthetic outcome was reported in half of studies (n = 75, 50.7 per cent) using mainly subjective, non-validated measurement tools. The time point at which aesthetic assessment was conducted was highly variable, and only defined in 48 (64.0 per cent) studies and none included a preoperative baseline for comparison. Few studies reported quality of life (n = 30, 20.3 per cent), functional outcomes (n = 5, 3.4 per cent) or resource use (n = 28, 18.9 per cent). CONCLUSION Given the oncological equivalence of TM and mastectomy, treatment decisions are often driven by aesthetic and functional outcomes, which are infrequently and inconsistently reported with non-validated measurement tools.

Abstract
Esthetic masculinization of the chest wall is one of the first surgical steps in female-to-male transsexual (FTMTS) reassignment.This surgical procedure is not a simple mastectomy: it is required for removal of breast tissue with glandular resection and skin excess revision, to reduce and replace the nipple-areola complex in the right location, minimizing chest wall scars. The creation of an esthetically pleasing male chest allows the patient to live at ease in the male gender role.In this article, we present our series of 68 FTMTSs who underwent bilateral mastectomies for surgical sexual reassignment (a total of 136 mastectomies) according to our algorithm, in the period between January 2010 and December 2017. We selected 4 different operative procedures, classified as subcutaneous ("pull-through" and "concentric circular" techniques) and skin extended ("ultrathin vertical bipedicle" and free nipple graft).We achieved a total complication rate of 6.6%, less than that reported in the literature; additional procedures for esthetic improvements were performed in 14.7% of cases. The mean patient satisfaction was approximately 4.57% of a maximal value of 5 (excellent).To help surgeons in choosing the most appropriate FTMTS surgical technique and to reduce unfavorable results, we propose the use of our treatment algorithm in preoperative evaluation of the chest wall according to the breast volume, degree of glandular ptosis, and skin elasticity.

Paving the way for changing perceptions in breast surgery: a systematic literature review focused on oncological and aesthetic outcomes of oncoplastic surgery for breast cancer. Breast Cancer 2019; 26:416-427. [PMID: 30955172 DOI: 10.1007/s12282-019-00968-1] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2018] [Accepted: 03/16/2019] [Indexed: 11/30/2022]
Abstract
BACKGROUND The emphasis on aesthetic outcomes and quality of life after breast cancer surgery has motivated breast surgeons to develop oncoplastic breast conserving surgery (OPS). Training programs are still rare in most countries, and there is little standardization, which challenges the scientific evaluation of these techniques. This systematic review aims to assess oncological and cosmetic outcomes of OPS. METHODS After a strict selection process with precise inclusion and exclusion criteria, oncologic and aesthetic outcomes of oncoplastic surgery were searched, using the MEDLINE database up to September 30th, 2017. Available published literature was classified in levels of evidence. After a thorough screening process, only studies with the best level of evidence were included on selection. Systematic reviews and meta-analyses were not included for methodological reasons. RESULTS Titles and abstracts of 2.854 citations were identified and after screening 15 prospective studies including 1.391 patients were reviewed and scored in detail. Local relapse was found in 2.8% of cases with a wide range of follow-up (from 6 to 74 months). Close margins were retrieved in 11% of cases and positive margins in 9.4% of cases. Mastectomy was implemented in 6.9% of breast cancer patients to whom OPS was performed. Good cosmetic outcomes were detected in 90.2% of patients undergoing OPS, leaving open issues for who should perform cosmetic evaluation and which method should be used. CONCLUSION Tumor margins, mastectomy rates, and cosmetic outcomes of OPS have to be further improved by standardizing various aspects of OPS. Research efforts should focus on level I evidence assessing both oncological and aesthetic outcomes of OPS and survival rates.

Abstract
BACKGROUND AND OBJECTIVES Reduction Mammaplasty (RM) in breast cancer allows mammary remodeling after wide excisions. We aimed to analyze the complications, survival, and quality of life after RM. METHODS Retrospective study of women who underwent a surgical intervention for breast cancer between 2000 and 2016. Patients were divided into two groups: RM and tumorectomy. Postoperative complications, survival and quality of life were assessed using the Breast-Q questionnaire. RESULTS A total of 801 patients were evaluated, with a mean follow up of 84 months. RM patients experienced a longer operating time and hospital stay, and a higher proportion of tissue necrosis compared to tumorectomy patients (P < 0.001). No significant differences were observed regarding rate of re-excision or rate of mastectomy, but the recurrence rate at 10 years was higher for RM patients (P < 0.03). Patients who underwent RM reported optimal satisfaction with the breast and a good quality of life. CONCLUSIONS RM is a useful approach in breast cancer surgery, with a low rate of re-excision and mastectomy. Overall survival at 10 years is similar to that associated with tumorectomy, though with a higher rate of local recurrence. Patient satisfaction and quality of life appears to be good one year after radiotherapy.

Abstract
Background The aim of this study was to assess the usefulness of the breast segmentectomy with rotation mammoplasty (BSRMP) in conserving therapy for an extensive ductal carcinoma in situ (DCIS) with or without an invasive component. Methods Thirty-six women with DCIS visible as large area of microcalcifications distributed out of the retroareolar area regardless of the quadrant were studied prospectively. All the patients underwent BSRMP and axillary procedure (31 sentinel node biopsy, 5 axillary dissection) followed by radiotherapy. In each case, follow-up was carried out carefully and special effort was made to identify postoperative complications. Cosmetic result was judged 6 months after radiotherapy by the patient herself and two surgeons being rated as poor, mediocre, medium, good or excellent. Results Operation was completed without any difficulties in all the cases. Appropriate BSRMP was easily done after the skin marking. Regardless of the type of axillary approach, it was conveniently performed. Wound was healed by primary adhesion; skin or breast tissue necrosis did not develop. Neither haematoma nor surgical site infection was observed. In none of the patient, centralisation of the nipple-areola complex (NAC) was needed. Three patients (8.3 %) with close margins (1 mm or less) successfully underwent subsequent re-excision. The scar did not result in any impairment of arm movement. Cosmetic outcome was evaluated by the women as excellent and good in 55 (87 %) and 8 (13 %) cases, respectively, while by the surgeons as excellent, good and medium in 52 (82 %), 8 (13 %), and 3 cases (5 %), respectively. Conclusions BSRMP is a simple and safe technique achieving good cosmetic results without NAC centralisation and giving the wide and easy access to axilla for both sentinel node biopsy and lymphadenectomy. It can be helpful in cases of extensive, radially spreading tumours (in particular DCIS or invasive cancers with intraductal component), eccentric lesions, or superficially located cancers when the neighbouring skin is excised. However, due to its limitations (long incision, difficult subsequent mastectomy, possibility of scar placement in the visible area of decollete), a careful patients’ selection should be done. Further studies are needed to assess long-term cosmetic outcomes including delayed post-radiotherapy effects.

Abstract
INTRODUCTION Breast conservation is a legacy of Umberto Veronesi who laid the groundwork for the preservation of the body image of women affected by breast cancer (BC) with the Milan I study in the late 70ies of the last millennium. Breast conservative surgery (BCS) has two aspects: oncological safety of tumour resection with free margins and aesthetic preservation of the breast. Determinants of local control used to be T-size, nodal status and receptor status until biologically driven concepts defined risk of recurrence on the basis of molecular portraits. We explored whether these concepts of intrinsic subtypes prove at a large scale in the context of BCS and which surgical techniques procure best oncological and aesthetic outcomes, avoiding re-excision and necessity of conversion to mastectomy. PATIENTS AND METHODS We analyzed 1035 BCS patients with primary unilateral breast cancer (2004-2009) with regards to the local recurrence as a function of tumour location, surgical technique, resection volume, T-size, nodal status, grading, histopathological and intrinsic subtype and margins. RESULTS Five surgical techniques were applied to 944 eligible patients at a median follow-up of 5.2 years with the following frequency: Glandular rotation mammoplasty (63.8%), tumour-adapted rotation mammoplasty (20.9%), dermoglandular rotation mammoplasty (6.7%), 4.4% (lateral thoracic wall advancement), 0.7% latissimus dorsi flap (0.7%) and others (13.5%). Tumour-free margins were achieved in 88.6% of all patients at first surgery. Recurrence was independent of the surgical technique used, resection volume, T-size (in a T1/T2-cohort), nodal status (in low N-stages: NO/N1) and histopathology (inv.-ductal vs. lobular), however non-invasive subtype (DCIS), high grading (G3 vs. G1), non-luminal Her2 positive BC and triple-negative breast cancer (TNBC) were significantly associated with local recurrence. CONCLUSIONS Five defined oncoplastic principles presented in our nomogramme (targeted breast surgery) allow the reconstruction of major segmental resection defects during breast-conserving therapy with high clinical applicability and result in favorable oncological and aesthetic outcome. Recurrence was not a function of traditional prognostic factors like T-size or nodal status (in a T1/T2, N0/N1 cohort), but of grading, intrinsic subtypes and non-invasive breast cancer components. Lobular histology, multi-centricity and DCIS were predictive for breast preservation failure and conversion to mastectomy.
