Feasibility of perforator flaps in Day surgery. A retrospective study through a two-years' experience.

BACKGROUND: Day surgery is developing and its popularity is increasing for a variety of reasons: economic constraints, changes in professional practices, a greater adhesion of the patient. In an era of progress in surgical procedures, pedicled-perforator flaps reducing donor site morbidity and avoiding micro-anastomosis could take their place in Day surgery if planned and managed by an experienced team. METHODS: In the period January 2019 to January 2021, we performed perforator flaps for soft tissue coverage in ambulatory setting. The patients were included retrospectively and data were collected by reviewing the medical records. Major and minor complications were recorded. RESULTS: The retrospective cohort included 32 surgical procedures in 32 patients. In all cases, perforator flaps were realized for resurfacing soft tissue defects consequent to oncodermatology surgery (84.3%), soft tissue sarcoma surgery (12.5%), invasive ductal breast carcinoma (3.1%). Major complications needing a surgical revision overcame 3/32 times (9.4%). In these cases, a failure requiring the drop off the flap overcame once. The average wound healing time was of 33 days (15-90) and the mean duration of follow-up was 9.6 months (1-22). CONCLUSION: The low complication rate in our series suggests that this first experience on perforator flaps in outpatient surgery is promising in terms of safety and feasibility. Day surgery could be a practical option for this type of surgical procedures avoiding the conventional department's saturation and allowing the delivery of proper surgical cares.

Improved nationwide survival of sarcoma patients with a network of reference centers.

BACKGROUND: We investigated the impact of the implementation of a network of reference centers for sarcomas (NETSARC) on the care and survival of sarcoma patients in France since 2010. PATIENTS AND METHODS: NETSARC (netsarc.org) is a network of 26 reference sarcoma centers with specialized multidisciplinary tumor boards (MDTBs), funded by the French National Cancer Institute (INCa) since 2010. Its aims are to improve the quality of diagnosis and care of sarcoma patients. Patients' characteristics, treatments, and outcomes are collected in a nationwide database. The objective of this analysis was to compare the survival of patients in three periods: 2010-2012 (non-exhaustive), 2013-2015, and 2016-2020. RESULTS: A total of 43 975 patients with sarcomas, gastrointestinal stromal tumors (GISTs), or connective tissue tumors of intermediate malignancy were included in the NETSARC+ database since 2010 (n = 9266 before 2013, n = 12 274 between 2013 and 2015, n = 22 435 in 2016-2020). Median age was 56 years, 50.5% were women, and 13.2% had metastasis at diagnosis. Overall survival was significantly superior in the period 2016-2020 versus 2013-2015 versus 2010-2012 for the entire population, for patients >18 years of age, and for both metastatic and non-metastatic patients in univariate and multivariate analyses (P < 0.0001). Over the three periods, we observed a significantly improved compliance to clinical practice guidelines (CPGs) nationwide: the proportion of patients biopsied before surgery increased from 62.9% to 72.6%; the percentage of patients presented to NETSARC MDTBs before first surgery increased from 31.7% to 44.4% (P < 0.0001). The proportion of patients with R0 resection on first surgery increased (from 36.1% to 46.6%), while R2 resection rate decreased (from 10.9% to 7.9%), with a better compliance and improvement in NETSARC centers. CONCLUSIONS: The implementation of the national reference network for sarcoma was associated with an improvement of overall survival and compliance to guidelines nationwide in sarcoma patients. Referral to expert networks for sarcoma patients should be encouraged, though a better compliance to CPGs can still be achieved.

The star approach, a surgical approach for skin sparing mastectomy and central lumpectomies.

When preservation of the nipple-areolar complex (NAC) is not possible in oncologic breast surgery, the traditional approaches are either a horizontal incision centered on the NAC resulting in visible scars and breast distortion, or a round block with risk of healing difficulties. To address these concerns, the authors propose a star approach technique for skin sparing mastectomies and lumpectomies of central breast tumors. During the oncologic surgery, the NAC is removed with four cutaneous extensions, which can be closed as a cross-shaped scar. The scarring is similar in size to the original NAC diameter and can easily be covered by the NAC reconstruction. This technique offers good exposure during surgery, a good aesthetic result with limited scarring, no breast deformity, correction of breast sagging, and high-quality healing.

Muscle sparing latissimus dorsi flap for reconstruction of a large chemo-necrosis of the chest wall: A case report.

BACKGROUND: Extravasation of chemotherapeutic agents is a common complication in cancer centers. In severe cases involving large tissue necrosis, surgery may be needed to resect necrotic tissues and to cover the exposed areas. CLINICAL CASE DESCRIPTION: A 71 years old women was referred to our unit two month after extravasation of epirubicin from an implanted port-a-cath with a large chemonecrosis of the anterior chest wall. She presented an evolutive tissue necrosis extending from the upper anterior thoracic region to the right breast. Surgical debridements and negative wound pressure therapy were necessary in order to obtain clean areas. The final chest wall defect was covered using a Muscle Sparing Latissimus Dorsi pedicled flap. This surgical management have permitted a satisfying wound healing and functional recovery without any complication. CONCLUSION: Chemotherapeutics' extravasations can be a severe complication of oncologic treatment and have to be discussed between oncologists and plastic surgeons to find the most effective and suitable solution with consideration of the specificities of cancer therapy. In chest wall skin defect, the use of muscle sparing latissimus dorsi pedicled flap is a robust solution with low morbidity of the donor site.

[Complications of autologous breast reconstruction]. / Complication des lambeaux en reconstruction mammaire.

Flap reconstruction techniques are increasingly desired by French's patients and it represents almost half of breast reconstruction indications in 2017. The main reasons of this statistics are the growing concerns of the patients with breast implant of developing BIA-ALCL, as well as their desire of having a more natural reconstruction results without having any foreign bodies. The multiplication of autologous reconstruction techniques, especially microsurgical techniques which has been popularized in the recent years, makes possible to propose a reconstruction to the majority of patients without an implant. This type of reconstructions is associated with a significant number of complications; thus, a proper selection of patient should be done and a good knowledge of the surgical technique by the surgeon to reduce the complication. Our proposed study is divided into two main parts, the complications of the flap and the complications at the donor site. Based on the experience of our plastic surgery department in immediate and delayed breast reconstruction, the objective of this article is to describe and to analyze the possible complications of breast reconstruction by a flap and their surgical management in intra and post operatively. Our goal is to provide an algorithm for our young colleagues in order to obtain better understanding of this type of interventions difficulties and to provide an appropriate care in the event of complication, also to provide optimal care to the patients who wish to undergo autologous flap reconstructions.

[Morbidity of bodylift. Evaluation of 111 patients over 5 years]. / Morbidité de la dermolipectomie abdominale circulaire. Série rétrospective de 111 patients sur 5 ans.

INTRODUCTION: The management of patients with weight loss sequelae, sometimes major, is increasingly well standardized. However, this surgery is not without risk. Complications of bodylift are more frequent than those of conventional abdominoplasties. The objective of this study was to evaluate the morbidity associated with this surgery through a retrospective, single-center study. MATERIALS AND METHODS: One hundred and eleven circular abdominaloplasties were conducted between June 2011 and September 2015 in the plastic surgery department of the university hospital of Toulouse. Minor and major complications were identified and analyzed. RESULTS: Frequency of postoperative complications was 44.1% in our series. Major complications have involved 15.3% of patients. Blood transfusions (9%) and hematoma requiring reoperation (7.2%) were the most frequent major complications. We found significantly more major complications in patients with important fat resection with a cut off at 3200 g (P=0.02). Men experienced significantly more major complications than women (P=0.005). The average delta-BMI (before and after weight loss) was significantly higher in the group of patients with the highest percentage of minor complications (P=0.045). Indeed, a high delta-BMI (greater than 19.5) was associated with an excess risk of minor complications in our population. CONCLUSION: Democratization and progress in the field of bodylift should not obscure the fact that it is, in reality, a procedure at risk. While we manage increasingly better cosmetic results and thromboembolic complications, it still persists many complications.

[Radiotherapy as conservative therapy for sarcomas within the irradiated field]. / Place de la radiothérapie dans le traitement conservateur des sarcomes en territoire irradié

PURPOSE: To describe long-term outcome after combined-modality treatment including radiation therapy in patients with localized sarcoma within irradiated field. PATIENTS AND METHODS: Individual clinical data from all consecutive patients diagnosed and treated for a localized sarcoma within irradiated field between January 2000 and October 2011 at the Institut Claudius-Regaud, Toulouse, France, were retrospectively reviewed. RESULTS: Twenty-seven patients were eligible for this study. Ten patients were re-irradiated with a rate of unresectable, gross or microscopically positive margins disease significantly higher than the rest of the cohort (90% vs. 12%; P<0.001). After a median follow-up of 3.8 years, there is a non-significant trend toward longer 4-year relapse free survival in the subgroup of patients who received adjuvant or definitive radiation therapy compared to the rest of the cohort (53% vs. 27%; P=0.09) with an acceptable toxicity profile allowing conservative management. CONCLUSION: The complete surgical resection sarcoma within irradiated field is often difficult to achieve enhancing the risk of relapse. Radiation therapy should be discussed when faced with an unresectable tumour or after suboptimal surgery as part of intensified local management with a curative intent.

Dermatofibrosarcoma protuberans: margins reduction using slow-Mohs micrographic surgery. Experience with 35 patients.

INTRODUCTION: Dermatofibrosarcoma protuberans (DFSP) is a potentially malignant dermal mesenchymal tumour with a high risk of local recurrence. DFSP presents a sprawling appearance whose complete excision requires important margins. DFSP was initially resected with a 5cm excision margins, and more recently 3cm then 2cm margins were recommended. Mohs micrographic surgery (MMS) helps reduce these margins thanks to a 3-dimensional excision around the tumour, which is analysed in its entirety. We used the modified MMS called slow-MMS and tried every time it was possible to perform direct closure. METHODS: Thirty-five patients presenting a DFSP between 2004 and 2013 within the Plastic Surgery unit at Claudius Regaud Institute were included in this retrospective study. The patients were treated with slow-MMS using paraffin-embedded sections. RESULTS: One surgery was necessary for 72% of patients. For 17%, we had to perform a second surgery, and for 11% a third one. Our median clinical excision margins was 17mm (range 9.0:30.0). After a median follow-up of 46 months (range 35.2:60.2), we didn't observe any recurrence. Only one case required a local flap; for the others, the loss of substance was resolved with a direct closure. CONCLUSION: Slow-MMS enabled a local control of the margins without recurrence at 46 months in our series. Besides, it helps performing smaller margins than wide excision and thus preserving the tissues. In our opinion, this is the treatment of choice regarding DFSP for which tissue sparing is essential. It seems particularly appropriate near functional areas or on the face.

Role of radiation therapy in the conservative management of sarcoma within an irradiated field.

PURPOSE: To report on clinical outcome and toxicity profile after combined treatment that included radiation therapy (RT) in patients with localized sarcoma within an irradiated field. PATIENTS AND METHODS: Individual clinical data from all consecutive patients diagnosed and treated for a localized SIF between January 2000 and October 2011 at the Institut Claudius Regaud, Toulouse, France, were retrospectively reviewed. Outcomes of patients with SIF who underwent adjuvant or definitive radiotherapy were compared with patients who did not receive further RT. RESULTS: Of the 27 patients eligible for this study: surgery alone (S), surgery followed by RT (S + RT) or definitive RT (RT) was performed in 16, 8 and 2 cases respectively. The rate of unresectable, gross or microscopically positive margin disease among the 10 re-irradiated patients was significantly higher than the non re-irradiated group (90% vs. 12% p < 0.001). After a median follow-up of 3.8 years, there was a trend toward longer survival and better local control in the subgroup of patients who received adjuvant or definitive RT compared to the rest of the cohort with an acceptable toxicity profile. The 4-year relapse free survival rates of patients treated with and without RT were 53% and 27% respectively (p = 0.09). CONCLUSION: SIF complete surgical resection is often difficult to achieve, enhancing the risk of relapse. RT should be discussed in case of unresectable tumor or after suboptimal surgery as part of intensified local management that has a curative intent.

"Body-lift"-like pattern for the simultaneous bilateral superior gluteal artery perforator flap in breast reconstruction.

UNLABELLED: Prophylactic mastectomies have increased during the last 10 years. Breast reconstructions with free flaps are performed because they provide natural and long-lasting results. In bilateral mastectomy, a simultaneous bilateral superior gluteal artery perforator (SGAP) flap can provide good reconstruction with autologous tissue and low donor-site morbidity. This report describes the case of a "body-lift"-like pattern for a simultaneous bilateral SGAP flap procedure. This innovative pattern provides good aesthetic results for the abdomen and buttocks and preserves the option of using a deep inferior epigastric artery and vein perforator (DIEP) flap in case one SGAP flap fails. After 3 months, the patient was very satisfied with the results. The SGAP flap remains undeniably an alternative to the DIEP flap when the abdominal excess is insufficient for a bilateral reconstruction.

[Histological techniques in oncodermatology]. / L'apport des techniques anatomopathologiques en oncodermatologie.

The skin oncology or "oncodermatology" requires a surgical treatment in most cases. For some surgeons, the oncodermatology takes a very important part of their practice. In the course of diagnostic and therapeutic of skin lesions, the pathologist plays now an essential role. He will guide our surgery. The techniques used by this specialist are numerous. Therefore, the objective of this paper is to review the different histological methods used to improve our management of skin tumors.

[Dermatologic adverse events of the new targeted anticancer therapies used in oncodermatology]. / Toxicité dermatologique des nouvelles thérapies ciblées anticancéreuses utilisées en oncodermatologie.

The management of oncology patients has been deeply modified over recent years by the development of new targeted anticancer therapies. Though these new therapies generally have a good safety profile, the skin is probably the organ most affected by their toxicity, in terms of frequency and symptom diversity. This review describes the most frequent cutaneous side effects induced by the new targeted therapies used in oncodermatology, whether they are well-established drugs such as EGF receptor inhibitors (cetuximab, erlotinib) or imatinib, or new treatments for metastatic melanoma such as selective BRAF (vemurafenib) or MEK inhibitors (selumetinib) and CTLA-4 monoclonal antibodies (ipilimumab).

[Outcome at 18 months after the recall of Poly Implant Prosthesis. Experience of a cancer center]. / Bilan à 18 mois du retrait du marché des prothèses Poly Implant Prothèse. Expérience d'un centre anticancéreux.

INTRODUCTION: On March 30, 2010, AFSSAPS (sanitary French) issued a medical alert about breast implants "Poly Implant Prothese" (PIP), because it was shown that its failure rate was higher than of other manufacturers. This alert was accompanied by a suspension of sales and use of breast implants PIP. Since the announcement of this decision, the Institut Claudius Regaud (ICR) has set up a crisis unit to best meet the demands and questions concerning patients who had PIP implants. After 18 months of the beginning of the crisis, we decided to review the consequences of this decision. PATIENTS AND METHODS: This is a retrospective study of all patients who underwent breast reconstruction with a prosthesis PIP since 2006. We are interested in managing of the crisis, the fate of patients and the problems of implants. RESULTS: In total 128 PIP prostheses were implanted on 116 patients. These were all cases of asymmetric anatomic implants placed in 91 cases in immediate breast reconstruction and of breast-delayed reconstruction in 25 cases. Twelve patients had a contralateral PIP prosthesis. After careful analysis of the records, we found that 18 patients (16%) had received a change of prosthesis or simple removal of the prosthesis before the beginning of the crisis. No prosthesis was broken. After the retrospective chart review we found that we reoperated 61,2% of patients and explanted 59,4% of prostheses PIP. In 31 cases (26,7%), another surgery was associated with the change of prosthesis. Of the 76 explanted prostheses, ten of them had an abnormality (13,1%). Three implants (3,9%) were ripted. Six implants (7,9%) had a phenomenon of perspiration. The average life span of these prostheses was of 21,3 months. Among patients who were reoperated, we observed three postoperative complications (3,9%). CONCLUSION: More than 18 months after the withdrawal on the market of breast implants PIP, we reviewed almost all patients implanted at our institution. To date, 60% of patients no longer have this prosthesis in place, but 16% of patients with this specific breast implant had already been remove before March 2010. Eighteen percent of implants had an abnormality and three had a rupture. In this retrospective study we also found that the care of our patients could be improved, including the legibility of the monitoring and in the administrative field.

[The adipose tissue transfer in the mammary parenchyma (part II): Review of the literature on the carcinologic risks]. / Transfert de tissu adipeux dans le parenchyme mammaire (2e partie) : y a-t-il un risque carcinologique ? Revue de la littérature.

The adipose tissue transfer in the mammary parenchyma is a controversial area that generates passionate debates both in France and abroad. This second article presents a review of the literature on the interactions of fat transfer and the risk of developing breast cancer. Analysis of the results of the fundamental literature on the effects of adipose tissue in breast cancer development is troubling. At this stage, these results can not be transposed to humans as there are no studies showing a clinical correlation with suspected factors. It is difficult today to propose a pragmatic attitude on the transfer fat tissue into the breast. Given the results of the literature, we believe that the recommendations of caution of various scientific societies is well justified. The development of prospective study seems necessary to address this controversial issue.

[The adipose tissue transfer in the mammary parenchyma (part I): Review of the literature on modifications of the radiological images]. / Transfert de tissu adipeux dans le parenchyme mammaire (première partie) : les modifications des images radiologiques. Revue de la littérature.

The adipose tissue transfer (ATT) in the mammary parenchyma is a subject of controversy and generates passionate debates in scientific meetings. So far, many phenomena remain unexplained. Among these phenomena, changes in mammogram images generated by the grafted adipose tissue and the interactions between the grafted adipose tissue and a clinically undetectable breast cancer are the most important. We will present a series of articles with a critical analysis of the scientific literature on each of these phenomena. This first article presents the review of the literature on modifications of the radiological images after ATT. Two types of images are most common in mammograms after ATT. These are oil cysts and microcalcifications. Regarding to the presented review of literature, there is not yet sufficient evidence to prove a similarity or not between these images generated by the ATT and those from a breast malignancy. Therefore, clinically, patients must be included in a prospective clinical trial and in terms of research, the first step should be an exhaustive description of radiological images after ATT and a comparison of these images to images of malignancy. So, it's important to include these patients in prospective protocols with close and long term follow-up.
