RESUMEN
BACKGROUND: Breast cancer and its treatment remains a public health problem. There is still a lack of epidemiological data concerning complications and aesthetic results bound to radiotherapy after an immediate breast reconstruction. The objective of this study was to compare outcomes of immediate breast reconstruction regardless to the use of radiotherapy (history of radiotherapy or adjuvant radiation therapy), in order to determine risk factor of complications and bad aesthetic results. METHODS: We conducted a retrospective study between January 2014 and December 2016 at the hospital "Gustave Roussy" in Paris, concerning breast cancer patients who needed immediate breast reconstruction after total mastectomy. The primary endpoint was to assess the failure rate of reconstruction and the aesthetic result, the secondary endpoint assessed the early and late rate of complications. We realized a multivariate analysis in order to identify risks factors that may predict complications. RESULTS: Three hundred and thirty three patients have been included: 157 in the "radiotherapy group" compared to 176 in the "no radiotherapy group". Preoperative characteristics were comparable. Average follow-up was between 1 and 3years without missing. Patients who benefited from radiotherapy had an equal risk failure of reconstruction. The subgroup analysis revealed non-significant differences: 12.7% failure rate reconstruction in the "radiotherapy group" vs. 12.5%. We could notify a better rate of "excellent results" in the "no radiotherapy group": 35% vs. 8.2%. Secondary outcomes were comparable. CONCLUSIONS: Radiotherapy related to immediate breast reconstruction didn't increase the failure rate of reconstruction or aesthetic results, comparatively to non-irradiated patients. It is therefore permissible to suggest an immediate breast reconstruction to any patients which would benefit from a total mastectomy followed by radiotherapy; in order to prevent them from a secondary breast reconstruction, who could be physically and psychologically more impactful.

BACKGROUND: The standard of care for sinonasal malignancies is a large surgical resection followed by radiotherapy. Midfacial defects resulting from maxillectomy require a complex reconstruction procedure. Given their adaptability, chimeric flaps such as latissimus dorsi-scapular (LDS) free flaps appear to be a good option. MATERIAL & METHODS: We performed a single-center retrospective study of consecutive patients with sinonasal cancers where a LDS free flap was used for reconstruction. We assessed the postoperative complications and the functional, aesthetic and oncologic outcomes. RESULTS: Eighty-four patients were included. Primary tumors were staged as T4a in 68% of cases; 38.3% of the patients received induction chemotherapy and 82.7% received adjuvant radiotherapy. Based on our classification of midfacial and palatal defects, the majority of the patients (69%) had a type IIa with interruption of the three facial pillars. The orbital floor was removed in 55.9% of cases. The median follow-up was 45â¯months. Total flap necrosis with no possible revascularization occurred in 5.9% of cases. For the orbital reconstruction, a revision procedure was needed for necrosis and/or infection of the costal cartilage graft in eight cases (17%). More than 90% of the patients had no functional disorders regarding speaking, swallowing and chewing. Soft palate involvement was a prognostic factor of speech (pâ¯<â¯10-4) and swallowing (pâ¯=â¯.005) disorders. Dental rehabilitation was realized in 70.2% of the patients. No severe complications were observed in the donor site, except for one seroma. CONCLUSION: A LDS free flap is a reliable technique for the reconstruction of complex midfacial defects.

Immediate breast reconstruction showed many advantages in terms of aesthetic and functional results and improvement of quality of life when compared to delayed breast reconstruction. Previous radiotherapy or the use of adjuvant treatments such as radiation therapy, or chemotherapy are no longer a contraindication for immediate breast reconstruction. However, it is important to respect certain rules in order to decrease the risk of complications: the choice of reconstruction technique, the management of the skin envelope according to the breast shape you want to create, the time delay between the first and the second stage of reconstruction depending on a possible adjuvant treatment.

Immediate breast reconstruction indications extend to infiltrating carcinomas, due to new matrix implant coverage techniques and the development of perforator flaps. These techniques allow adjuvant treatments. However, the decision of immediate reconstruction must be discussed with the oncological multidisciplinary team and the benefits/risks must also be evaluated in relation to the morphology of the patients and their co-morbidities. The chosen type of mastectomy: conventional or skin sparing and/or nipple sparing depends on the shape and volume of the breast, the localization of the tumor in the breast and the distance from the nipple areola complex (NAC). We describe an algorithm to allow, in the case of therapeutic mastectomy with or without adjuvant radiotherapy, an immediate reconstruction with implants or free or pedicled flaps.

Background: The cyclin-dependent kinase 4 (CDK4)/6 inhibitor Palbociclib is a new standard treatment in hormone-receptor positive breast cancer patients. No predictive biomarkers have been identified and no pharmacodynamics has properly been described so far. Patients and methods: Patients with early-breast cancer were randomized 3 : 1 to oral palbociclib 125 mg daily for 14 days until the day before the surgery versus no treatment. Primary objective was antiproliferative response defined as a natural logarithm of Ki67 expression at day 15 below 1. Secondary end points were subgroups analyses and safety. Exploratory analyses included search for predictive biomarkers. Immunostainings (Ki67, RB, pRB, p16, pAKT, pER, pCDK2, CyclinD1), FISH (CCND1) and gene expression (GE) arrays were carried out at baseline and at surgery. In addition, activating PIK3CA and AKT1 mutations were assessed at baseline. Results: 74 patients were allocated to palbociclib and 26 to control. Most patients (93%) were hormone-receptor (HR)-positive, whereas 8% were HER2-positive. Palbociclib led to significantly more antiproliferative responses when compared with control (58% versus 12%, P < 0.001), and to a significantly higher Ki67 decrease (P < 0.001). In the HR-positive/HER2-negative subgroup, this antiproliferative effect was even more marked in the palbociclib arm when compared with control (70% versus 9%, P < 0.001). Palbociclib treatment led also to a significantly higher decrease from baseline in phospho-Rb when compared with control (P < 0.001). Among treated patients, changes in Ki67 correlated with changes in phospho-Rb (Spearman rank r = 0.41, P < 0.0001). GE analyses confirmed a major effect on proliferation and cell cycle genes. Among treated patients, CCNE2 expression was significantly more decreased in antiproliferative responders versus nonresponders (P = 0.006). Conclusion: Short-term preoperative palbociclib decreases Ki67 in early-breast cancer patients. Early decrease of Rb phosphorylation correlates with drug's effect on cell proliferation and could potentially identify patients with primary resistance. Clinical trial registration: NCT02008734.

Robot-assisted surgery is more and more widely used in urology, general surgery and gynecological surgery. The interest of robotics in plastic and reconstructive surgery, a discipline that operates primarily on surfaces, has yet to be conclusively proved. However, the initial applications of robotic surgery in plastic and reconstructive surgery have been emerging in a number of fields including transoral reconstruction of posterior oropharyngeal defects, nipple-sparing mastectomy with immediate breast reconstruction, microsurgery, muscle harvesting for pelvic reconstruction and coverage of the scalp or the extremities.

The Indocyanine green (ICG) is a soluble dye that is eliminated by the liver and excreted in bile. When illuminated by an near-infrared light, the ICG emits fluorescence in the near-infrared spectrum, which can be captured by a near-infrared camera-handled device. In case of intravenous injection, ICG may be used as a marker of skin perfusion. In case of interstitial injection, it may be useful for lymphatic network mapping. In oncological and reconstructive breast surgery, ICG is used for sentinel lymph node identification, to predict mastectomy skin flap necrosis, to assess the perfusion of free flaps in autologous reconstruction and for diagnosis and treatment of upper limb secondary lymphedema. Intraoperative indocyanine green fluorescence might also be used to guide the excision of nonpalpable breast cancer.

Even though DIEP-SIEA flaps or latissimus dorsi musculocutaneous flap are the most frequently used, a wide variety of flaps have been described for autologous breast reconstruction. Concerning the choice of donor-site, the aim is to prevent and to limit the morbidity. That is why the donor-site should be carefully chosen, according to the morphology of the patient. Lumbar artery perforator flap (LAP) is an option for breast reconstruction, but it is not well known and its use is limited. This study summarizes the authors' early experience with free LAP flap for breast reconstruction. Three patients underwent immediate or delayed autologous breast reconstruction using a LAP flap. No vascular by pass was required to lengthen the pedicle. No partial or complete flap necrosis has been reported. There was no surgical donor-site complication. Mean operative time was 7hours. LAP flap can be considered as a good option for autologous breast reconstruction, especially in patients with unfavorable abdominal donor-site, and impossibility to use a DIEP flap.

The musculocutaneous tensor fascia latae flap was one of the first free flaps described. It is possible to harvest a flap with the same skin paddle, vascularized by a septo-cutaneous perforator running through the tensor fascia lata muscle septum and coming from the ascending branch of the lateral circumflex femoral artery. The DIEP is currently the workhorse of autologous breast reconstruction, but there are some contraindications. The septo-cutaneous tensor fascia latae perforator flap may be an alternative for women with lateral upper thigh lipodystrophy. Between 2010 and 2014, three flaps have been performed in two patients for delayed breast reconstruction (one case of unilateral reconstruction, and one bilateral). Perforators were identified by preoperative angiography. The intervention was performed in a two-team approach, in only one operative position. Perforators were located in the horizontal axis of the upper rim of the pubis bone. One perforator artery was dissected for each flap. The mean caliber of the pedicle was 2.8mm, and the mean length was 6.4cm. The operative time was 240minutes for unilateral flap, 375minutes for bilateral flap. There was no case of total or partial necrosis, or complications on the donor site. Cosmetic results were considered satisfying by patients and surgeons with the reconstructed breast as well as the donor site. Septo-cutaneous fascia lata perforator flap is an attractive flap for breast reconstruction in patients with DIEP contraindication and lateral upper thigh lipodystrophy. It has many advantages: easy to harvest, length and calibre of the pedicle, double team approach, only one operating position, quality of reconstruction. It is necessary to carry out a larger series of cases to study the complication rate in the donor site.

INTRODUCTION: Skin graft is still a method of choice for the coverage of temporal defects. But there are some disadvantages like a "patch" appearance, the need of dressing or longer healing time. Numbers of local flaps have been described for closing skin defects on temporal region. Yet, they may cause distortion of the surrounding tissues, especially in the temporal hairline and eyebrow. We present a series of seven local flaps based on small branches (SB) of the superficial temporal artery (STA) for the coverage of temporal defects, and discuss their advantages. PATIENTS AND METHODS: Supermicrodissection of SB of the STA was performed to obtain local flaps for reconstruction of temporal defects after skin cancer excisions in seven patients. Patient's age ranged from 70 to 88 years old and the diameter of defects ranged from 4 to 6 cm. All procedures were performed under local anesthesia except one. In all cases, defects were obtained after skin cancer excisions. RESULTS: The operative time ranged from 55 to 75 min. All flaps survived with an average follow-up of 8 months, reconstructions have maintained a cosmetically pleasing result. CONCLUSION: We believe that SB flaps may be a new option for reconstruction of temporal defects with the advantages of local flaps, without the inconvenience of a skin pedicle. Moreover, these flaps raise the question of the use of SB based flaps for the coverage of moderate-sized skin defects anywhere in the body, and open new fields in reconstructive surgery.

INTRODUCTION: Twenty-five cases of airway fire during tracheostomy have been reported in the literature. The authors describe a case observed in their centre 3 years ago, discuss the causes and preventive management and propose guidelines for prevention of this complication. CASE REPORT: A 66-year-old woman was intubated and ventilated with 100% oxygen during general anaesthesia for tracheostomy. On opening the trachea by monopolar diathermy, the oxygen present in the endotracheal tube caught fire, inducing combustion of the tube spreading to the lower airways. This airway fire was responsible for severe acute respiratory failure and the formation of multiple laryngotracheal stenoses. DISCUSSION: Combustion of the endotracheal tube due to ignition of anaesthetic gases induced by the heat generated by diathermy is responsible for airway fire. These various phenomena are discussed. Prevention is based on safety measures and coordination of surgical and anaesthetic teams.

The basal-cell carcinoma is the most frequent malignant tumor in human, usually involving the healthy sun-exposed skin of head and neck area, but thoracic and members localisations are possible. Macroscopic appearance is variable excepting the pathognomonic pearl. Periungual lesions are in this context very rare and we report the case of a 64-year-old man presenting with a basal-cell carcinoma on the thumb. A literature review was also performed and our purpose is to warn our colleagues about this quite often unrecognized pathology which may need a more aggressive treatment in case of delayed diagnosis, and to remind them that all chronic lesions impose a biopsy.

AIM: The internal breast pedicle flap is not a well-known technique yet. Anyway, it is effective for some of breast reconstructions and partial thoracic defects. This technique is applied to patients presenting breast hypertrophy. In this article, we present the experience of our department in this technique, considering its indications, surgery details, complications that may occur and subsisting interrogations about this surgical approach. MATERIAL AND METHODS: Two patients were treated with internal breast pedicle flap, one for controlateral breast reconstruction and one for coverage of partial thoracic defect. RESULTS: Patients were followed; flap survival and aesthetic results were analyzed during consultations. Results were good and similar to other well-spread reconstruction techniques. CONCLUSION: The internal breast pedicle flap is a relevant, reproducible and easy technique. Overall results are satisfying and allow the possibility of applying other techniques in case of failure. You have to keep in mind the risk of making a transfer of a potentially carcinogenic tissue for a patient having already presented a breast cancer.
