Oncologic safety of immediate autologous fat grafting for reconstruction in breast-conserving surgery.

IMPORTANCE: Autologous fat grafting (AFG), or lipofilling, has been used for immediate reconstruction at the time of breast-conserving surgery in order to achieve a satisfactory cosmetic outcome in patients with breast cancer and an unfavorable tumor-to-breast volume ratio or unfavorable tumor location. However, the oncologic safety of this technique is still unclear. OBJECTIVE: To determine whether AFG performed simultaneously with breast-conserving surgery is associated with differences in local relapse rates and disease-free survival. DESIGN: Matched retrospective cohort study. SETTING: Tertiary referral center. PARTICIPANTS: Patients undergoing breast-conserving surgery with or without AFG between 2004 and 2016 were retrospectively enrolled and matched for age, staging, grade, tumor histology, and tumor immunohistochemical profile. MAIN OUTCOME(S) AND MEASURE(S): The cumulative incidence of locoregional recurrence (LRR) and disease-free survival were the primary end points, while distant recurrence and overall survival were the secondary end points. RESULTS: A total of 320 patients were followed. Cases were matched with controls at a 1:4 ratio. There was no difference in LRR or distant recurrence of breast cancer between the two groups. The annual LRR rate was 0.86% in patients who received immediate AFG vs. 0.7% in patients undergoing breast-conserving surgery alone (p ≥ 0.05). Number of lymph nodes was the sole independent risk factor for local recurrence (p = 0.045). No significant differences in disease-free survival rates were found between the groups. CONCLUSIONS AND RELEVANCE: At a mean follow-up of 5 years, no significant differences in locoregional recurrence rates were found between patients who received immediate AFG and those who underwent breast-conserving surgery alone. These findings corroborate previous research demonstrating the oncological safety of immediate AFG reconstruction, further suggesting that this technique as a safe, effective way to achieve optimal cosmetic outcomes in primary breast cancer surgery without jeopardizing oncologic outcomes.

Breast-Conserving Surgery with Immediate Autologous Fat Grafting Reconstruction: Oncologic Outcomes.

INTRODUCTION: Autologous fat grafting (AFG; lipofilling, lipografting) has been used in delayed breast reconstruction. Recently, it has also been investigated as an alternative for immediate reconstruction in patients submitted to breast-conserving surgery (BCS). Although good aesthetic results have been reported, the oncologic safety of the procedure remains under investigation. This article aims to assess oncologic outcomes of patients submitted to BCS with immediate AFG reconstruction. METHODS: This study consisted of 65 patients undergoing BCS with AFG between January 2010 and January 2017. They were closely followed after surgery for a median period of 40.8 months. Locoregional and systemic recurrences were the primary endpoints of this study. RESULTS: Ten patients developed cancer recurrence (15.4%). The median time for recurrence was 58.9 months. Only two patients presented locoregional recurrence (LRR) (3.07%). Five patients had systemic recurrence (7.69%), and three had both systemic and LRR (4.61%). Median disease-free survival (DFS) was 42.2 months, and overall survival (OV) was 44.3 months. Recurrences were significantly associated with the number of metastatic axillary lymph nodes detected. CONCLUSION: Oncologic outcomes of immediate AFG are similar to the results previously reported in BCS without AFG. Locoregional and systemic recurrences are associated with the presence of axillary metastases. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

Immediate Reconstruction with Autologous fat Transfer Following Breast-Conserving Surgery.

This study explores the technical viability of autologous fat grafting for immediate partial breast reconstruction following the primary conservative surgery for breast cancer; restoring volume, shape, and symmetry to the treated breast. We analyze the impact in relation to mammographic follow-up and the subjective degree of satisfaction with esthetic results and although we didn't have any local failure during the observation period; we understand that is too early for any kind of conclusion. From June of 2010 to July of 2011, 20 patients were selected for breast-conserving surgery (BCS) with partial breast reconstruction with autologous fat grafting performed during the same operation by the same medical team. The fat graft was injected in the subcutaneous and intraglandular breast tissue around the resected area. We performed an overcorrection, predicting a resorbing of about 30-50% of the volume grafted. All patients received the literature-based recommendations for breast cancer treatment with complementary radiotherapy. The follow-up period after the completion of radiotherapy ranged from 13 to 29 months. The average volume grafted was 121 cc and it was 2.1 times larger than the resected volume. The esthetic scores were considered very good or good in the majority of cases. Mammograms were taken every 6 months after radiotherapy and only one patient had a mammogram classified as BI-RADS 3, suggesting fat necrosis. The remaining patients were classified as BI-RADS 2. Immediate autologous fat grafting is a promising technique for partial breast reconstruction after BCS. It is associated with high patient and physician satisfaction. It is an alternative for reconstruction of small- and medium-sized breasts. This technique has the advantage that enables the reconstruction of defects in areas difficult to repair, particularly in the upper inner quadrants. It also may reduce the need for major glandular or myocutaneous flaps mobilization.

The Effects of Melatonin on the Descending Pain Inhibitory System and Neural Plasticity Markers in Breast Cancer Patients Receiving Chemotherapy: Randomized, Double-Blinded, Placebo-Controlled Trial.

Background: Adjuvant chemotherapy for breast cancer (ACBC) has been associated with fatigue, pain, depressive symptoms, and disturbed sleep. And, previous studies in non-cancer patients showed that melatonin could improve the descending pain modulatory system (DPMS). We tested the hypothesis that melatonin use before and during the first cycle of ACBC is better than placebo at improving the DPMS function assessed by changes in the 0-10 Numerical Pain Scale (NPS) during the conditioned pain modulating task (CPM-task) (primary outcome). The effects of melatonin were evaluated in the following secondary endpoints: heat pain threshold (HPT), heat pain tolerance (HPTo), and neuroplasticity state assessed by serum brain-derived neurotrophic factor (BDNF), tropomyosin kinase receptor B, and S100B-protein and whether melatonin's effects on pain and neuroplasticity state are due more so to its impact on sleep quality. Methods: Thirty-six women, ages 18 to 75 years old, scheduled for their first cycle of ACBC were randomized to receive 20mg of oral melatonin (n = 18) or placebo (n = 18). The effect of treatment on the outcomes was analyzed by delta (Δ)-values (from pre to treatment end). Results: Multivariate analyses of covariance revealed that melatonin improved the function of the DPMS. The Δ-mean (SD) on the NPS (0-10) during the CPM-task in the placebo group was -1.91 [-1.81 (1.67) vs. -0.1 (1.61)], and in the melatonin group was -3.5 [-0.94 (1.61) vs. -2.29 (1.61)], and the mean difference (md) between treatment groups was 1.59 [(95% CI, 0.50 to 2.68). Melatonin's effect increased the HPTo and HPT while reducing the (Δ)-means of the serum neuroplasticity marker in placebo vs. melatonin. The Δ-BDNF is 1.87 (7.17) vs. -20.44 (17.17), respectively, and the md = 22.31 [(95% CI = 13.40 to 31.22)]; TrKB md = 0.61 [0.46 (0.17) vs. -0.15 (0.18); 95% CI = 0.49 to 0.73)] and S00B-protein md = -8.27[(2.89 (11.18) vs. -11.16 (9.75); 95% CI = -15.38 to -1.16)]. However, melatonin's effect on pain and the neuroplastic state are not due to its effect on sleep quality. Conclusions: These results suggest that oral melatonin, together with the first ACBC counteracts the dysfunction in the inhibitory DPMS and improves pain perception measures. Also, it shows that changes in the neuroplasticity state mediate the impact of melatonin on pain. Clinical Trial Registration: www.ClinicalTrials.gov, identifier NCT03205033.

Comparação dos resultados do tratamento cirúrgico da incontinência urinária de esforço por três diferentes técnicas cirúrgicas / Comparision of the results of the treatment of stress urinary incontinence with three different surgical procedures

Objetivo: analisar a prevalência de recidivas de incontinência urinária de esforço (IUE) tratada com diferentes técnicas cirúrgicas após pelo menos 2 anos de seguimento. Pacientes e métodos: avaliamos 55 pacientes com diagnóstico de IUE que submeteram-se à cirurgia para sua correção no Serviço de Ginecologia do Hospital de Clínicas de Porto Alegre, no período de 1992 a 1996. O seguimento pós-cirúrgico nesse Seruiço foi superior a 2 anos. As pacientes foram divididas em 3 grupos conforme a técnica cirúrgica empregada: Kelly-Kennedy (n=24), Burch (n= 23) e Marshall-Marchetti-Krantz (n=8). Resultados: não foram encontradas diferenças significativas quanto ao tempo de recidiva, idade na época da cirurgia e da recidiva, estado menopausal, uso de terapia de reposição hormonal (TRH), número de gestações e antecedentes de parto via vaginal. O número de casos com perineoplastia posterior foi maior no grupo de cirurgia de Kelly-Kennedy, sem, contudo, influir na recidiva. O grupo de cirurgia de Burch apresentou um tempo de menopausa maior quando da cirurgia (p<0,05). Conclusão: a taxa de recidiva com emprego das técnicas de Kelly-Kennedy, Burch e Marshall-Marchetti-Krantz foi respectivamente 29,2, 39,1 e 50 por cento, não diferindo do ponto de vista estatístico. A pesquisa de modificadores de risco para a incontinência urinária genuína não foi estatisticamente diferente nos três grupos estudados. Observou-se, contudo, que a totalidade das pacientes com cirurgia prévia recidivaram

Cirurgia de redução mamária e o mastologista / Breast reduction surgery and the breast surgeon

O tratamento cirúrgico de neoplasias mamárias benignas e malignas, assim como a abordagem de hipertrofias e assimetrias mamárias, requer do mastologista conhecimentos técnicos anteriormente utilizados apenas na área da cirurgia plástica. As técnicas de mamoplastia redutora utilizadas nos dias atuais derivam de técnicas descritas há muitos anos, com diferentes adaptações, objetivando sempre melhores resultados imediatos e tardios. As alterações estruturais e cicatriciais provocadas por esse tipo de cirurgia devem ser bem conhecidas e acompanhadas quando for empregada na solução de problemas oncológicos. Nesta breve revisão, discutem-se diversos aspectos técnicos e conceituais referentes à mamoplastia redutora com relevância na clínica mastológica atual.

New trends in breast cancer surgery motivated breast surgeons to get acquainted with surgical skills formerly only employed in aesthetic surgery. The modern surgical approach to reduction mammaplasty represents a surgical procedure improvement for better shape and reduced scars. Postsurgical changes, some of which may mimic cancer must be recognized and followed by mammography and clinical examination. In this review, we go through some issues about reduction mammaplasty and its importance for breast surgeons.
