Secondary orbital exenteration for conjunctival melanoma: A study of 25 cases.

INTRODUCTION: The treatment of conjunctival melanoma is most often conservative, but exenteration is sometimes necessary in order to achieve local control of the disease. It can be performed as a primary procedure in cases of locally advanced disease or as a secondary procedure after one or more recurrences. No benefit to secondary exenteration on patient survival has been demonstrated to date for conjunctival melanoma, and it is generally considered a palliative procedure. PATIENTS AND METHODS: Single-center retrospective study performed in the ocular oncology department of the Institut Curie (Paris, France). We included all patients who underwent secondary orbital exenteration for conjunctival melanoma between January 2008 and January 2016. RESULTS: Twenty-five patients underwent secondary exenteration for conjunctival melanoma. The maximum number of local recurrences prior to exenteration was six. Metastases occurred in 11 patients after exenteration and were more common when there was a greater tumor thickness on histology, if the tumor had not been treated initially in an ocular oncology center, or if there had been a greater number of local recurrences before the secondary exenteration was performed. Seventy-five percent of patients developed metastases when the exenteration was performed after 5 or 6 local recurrences. CONCLUSION: This study suggests that early secondary exenteration (i.e. after a number of local recurrences less than or equal to 4) may reduce the occurrence of metastases (and therefore improve patient survival) in conjunctival melanoma. Thus, secondary exenteration might be a curative surgery in some patients with recurrent disease.

[Breast reconstruction by TRAM]. / La reconstruction mammaire par TRAM.

The Transverse Rectus Abominis Musculocutaneous flap or TRAM was first described by Hartrampf in 1982. It consists in raising a abdominal musculocutaneous flap whose perforators vessels come from the superior epigastric vessels. We describe the surgical technique step by step with photos commented on different times.

Outcomes after surgical resection of lower eyelid tumors and reconstruction using a nasal chondromucosal graft and an upper eyelid myocutaneous flap.

INTRODUCTION: Surgical excision of large malignant lower eyelid tumors may cause important full-thickness eyelid defects. The reconstruction of such defects must restore the physiologic function of the eyelid and also re-establish an acceptable aesthetic result. MATERIALS AND METHODS: We report the outcomes of full-thickness excision of tumors extending over half of the horizontal lid length, followed by reconstruction using a nasal chondromucosal graft (coming from the ipsilateral ala of the nose) and an upper eyelid myocutaneous flap. Histological analysis of the specimen identified the tumor type and surgical margins for each patient. RESULTS: A total of 25 patients were operated using this reconstruction technique between March 2009 and June 2015: 17 basal cell carcinomas, 3 spindle cell carcinomas and 5 conjunctival melanomas (out of which 2 were associated with lentigo maligna). Mean duration of follow-up after surgery was respectively 36, 41 and 17 months for each of these 3 tumor types. We found a single local tumor recurrence and this was a basal cell carcinoma in a xeroderma pigmentosum patient. After surgery, none of the patients had lagophthalmos or ocular surface complications. Only 4 patients had a 1mm scleral show postoperatively; 3 other patients developed a small retraction of the eyelid after adjuvant radiotherapy and a 1mm scleral show occurred. CONCLUSION: In malignant tumors, complete surgical excision with histological margins adapted to tumor type prevents local recurrence in most cases. Our repair strategy of nasal chondromucosal graft and skin-muscle flap for large inferior eyelid defects provides good functional and aesthetic results.

The inframammary skin-sparing mastectomy technique.

Skin-sparing mastectomy and immediate implant-based breast reconstruction is technically a challenging procedures for women with large, ptotic breasts. This is usually performed using the Wise pattern incision resulting in an inverted T scar, which is associated with postoperative complications. The other challenge is obtaining adequate coverage of the prosthesis. We describe a technique that avoids the inverted T scar and provides a single horizontal scar with a double dermo-muscular layer coverage of the prosthesis.

Merkel cell carcinoma: value of sentinel lymph-node status and adjuvant radiation therapy.

BACKGROUND: Sentinel lymph-node (LN) biopsy (SLNB) is a valuable tool to assess the regional LN status in Merkel cell carcinoma (MCC). However, its prognostic value is still debated. This study was undertaken to assess SLNB usefulness for MCC management and to determine the impact of SLNB status on disease-free survival (DFS) and overall survival (OS) by comparing SLNB-positive versus -negative patients according to demographic, clinical and treatment characteristics. PATIENTS AND METHODS: In this retrospective, multicenter observational study, SLNB was proposed to all patients referred for clinically N0 MCC. Treatment schedule consisted of wide-margin surgical resection of primary MCC followed by adjuvant radiation therapy (aRT) to the primary site and, for SLNB-positive patients, radical LN dissection followed by regional aRT. Univariate and multivariate analyses determined factors associated with DFS and OS. RESULTS: Among 87 patients with successful SLNB, 21 (24.1%) were SLNB-positive. Median follow-up for the entire series was 39 months; respective 3-year DFS and OS rates were 73% and 81.4%, respectively. Univariate analysis (all patients) identified SLNB-negativity as being associated with prolonged OS (P = 0.013) and aRT (all sites considered) was associated with longer DFS (P = 0.004) and OS (P = 0.018). Multivariate analysis (all patients) retained SLNB status and aRT (all sites considered) as being associated with improved DFS (P = 0.014 and 0.0008) and OS (P = 0.0020 and 0.0019). Moreover, for SLNB-negative patients, tumor-bed irradiation was also significantly associated with prolonged DFS (P = 0.006) and OS (P = 0.014). CONCLUSIONS: The present study demonstrates that SLNB-negativity is a strong predictor of longer DFS and OS in stage I and II MCC patients. The similar benefit for aRT on tumor bed observed in this study has to be confirmed by a prospective study. The results advocate for SLNB being considered to all MCC patients.

[The role of nipple-sparing mastectomy in breast cancer: a comprehensive review of the literature]. / Mastectomie avec conservation de la plaque aréolo-mamelonnaire et cancer du sein. Mise au point.

BACKGROUND: The role of nipple-sparing mastectomy (NSM) for breast cancer is controversial as there is concern regarding its oncological safety and complication rate. We carried out a review of the literature to quantify the incidence of occult nipple malignancy in breast cancer, identify the factors influencing occult nipple malignancy, quantify locoregional recurrence rates and quantify NSM complication rates. METHODS: A search of the literature was performed using PubMed. Keywords used were "mastectomy", "nipple involvement", "nipple-sparing mastectomy", "skin-sparing mastectomy" "occult nipple malignancy" "occult nipple disease" "breast cancer recurrence". Articles were analyzed regarding incidence of occult nipple malignancy, potential factors influencing the incidence of occult malignancy and recurrence/complications following NSM. The incidence of occult nipple disease was compared between groups using Chi(2) or Fisher's exact tests for categorical variables and Student's t-tests for continuous variables. P values were considered significant<0.05. We identified nearly 30 studies compiling nearly 10 000 cases examining the rate of occult nipple malignancy and 23 studies compiling 2300 cases providing information on the rate of local recurrence after NSM. RESULTS: The overall rate of occult nipple malignancy was 11.5 %. Primary tumour characteristics influencing occult nipple malignancy were tumour-nipple distance<2cm, grade, lymph node metastasis, lymphovascular invasion, HER2 positive, ER/PR negative, tumour size>5cm, retro-areolar/central location and multicentric tumours. The overall nipple recurrence rate following NSM was 0.9 %, skin flap recurrence rate was 4.2 %. Full and partial thickness nipple necrosis rates were 2.9 % and 6.3 % respectively. CONCLUSION: NSM for primary breast cancer is appropriate in carefully selected patients. All patients should have retro-areolar sampling. There is strong evidence to suggest that suitable cases are well circumscribed single or multifocal lesions that have a TND>2cm. Tumours should be graded 1-2 and not have LVI, axillary node metastasis or HER2 positivity.

Extensive pure ductal carcinoma in situ of the breast: identification of predictors of associated infiltrating carcinoma and lymph node metastasis before immediate reconstructive surgery.

AIM: To identify predictors for infiltrating carcinoma and lymph node involvement, before immediate breast reconstructive surgery, in patients with an initial diagnosis of extensive pure ductal carcinoma in situ of the breast (DCIS). PATIENTS AND METHODS: Between January 2000 and December 2009, 241 patients with pure extensive DCIS in preoperative biopsy had underwent mastectomy. Axillary staging (sentinel node and/or axillary dissection) was performed in 92% (n = 221) of patients. Patients with micro-invasive lesions at initial diagnosis, recurrence or contralateral breast cancer were excluded. RESULTS: Respectively 14% and 21% of patients had a final diagnosis of micro-invasive carcinoma (MIC) and invasive ductal carcinoma (IDC). Univariate analysis showed that the following variables at diagnosis were significantly correlated with the presence of either MIC or IDC in the mastectomy specimen: palpable tumor (p = 0.002), high grade DCIS (p = 0.002) and detection of an opacity by mammography (p = 0.019). Axillary lymph node (ALN) involvement was reported in 9% of patients. Univariate analysis suggested that a body mass index higher than 25 (p = 0.007), a palpable tumor (p = 0.012) and the detection of an opacity by mammography (p = 0.044) were associated with an increased rate of ALN involvement. CONCLUSION: Skin-sparing mastectomy and immediate breast reconstruction (IBRS) has become increasingly popular, especially for patients with extended DCIS of the breast. This study confirmed that extended DCIS is associated with a substantial risk of finding MIC or IDC on the surgical specimen but also ALN involvement. Adjuvant systemic treatment and/or radiotherapy could be indicated for some of these patients after the surgery. Patients should be informed of the rate of 1) complications associated to IBRS that will potentially delay the introduction of systemic or local therapy 2) complications associated to radiotherapy after IBRS.

Assessment of poly-L-lysine dendrigrafts for virus concentration in water: use of MS2 bacteriophage as proof of concept.

AIMS: Virus detection has often been difficult due to a low concentration in water. In this study, we developed a new procedure based on concentration of virus particles on an innovative support: poly-L-lysine dendrigrafts (DGL), coupled with directed nucleic acid extraction and real-time PCR quantification. METHODS AND RESULTS: This method was evaluated using the bacteriophage MS2 as a model virus. This virus exhibited the size and structural properties of human pathogenic enteric viruses and has often been used to assess new supports of concentration. Moreover, this bacteriophage is also a faecal contamination indicator. In this study, many water filtration conditions were tested (volume of water, concentration, etc.), and more than 80% of bacteriophage were recovered after filtration on polymer, in most conditions. We demonstrated that the method was linear (slope = 0·99 ± 0·04 and Y intercept when x = -0·02 ± 0·28), valid (as manipulators, tested concentrations, volumes of sample and batch of polymer did not have any influence on concentration) and sensitive (allowing to concentrate up to 16,600-fold 1 l of sample and to detect and quantify down to 750 GC l(-1) and 7500 GC l(-1), respectively). CONCLUSIONS: To conclude, this support exhibits high interest to retain viruses and to allow to detect low concentration of virus in water. SIGNIFICANCE AND IMPACT OF THE STUDY: This study gives valuable advance in the methods of concentration and diagnosis of virus in water.

Prediction of axillary lymph node status in male breast carcinoma.

BACKGROUND: To evaluate whether predictive factors of axillary lymph node metastasis in female breast cancer (BC) are similar in male BC. PATIENTS AND METHODS: From January 1994 to May 2011, we recorded 80 non-metastatic male BC treated at Institut Curie (IC). We analysed the calibration and discrimination performance of two nomograms [IC, Memorian Sloan-Kettering Cancer Center (MSKCC)] originally designed to predict axillary lymph node metastases in female BC. RESULTS: About 55% and 24% of the tumours were pT1 and pT4, respectively. Nearly 46% demonstrated axillary lymph node metastasis. About 99% were oestrogen receptor positive and 94% HER2 negative. Lymph node status was the only significant prognostic factor of overall survival (P = 0.012). The area under curve (AUC) of IC and MSKCC nomograms were 0.66 (95% CI 0.54-0.79) and 0.64 (95% CI 0.52-0.76), respectively. The calibration of these two models was inadequate. CONCLUSIONS: Multi-variate models designed to predict axillary lymph node metastases for female BC were not effective in our male BC series. Our results may be explained by (i) small sample size (ii) different biological determinants influencing axillary metastasis in male BC compared with female BC.

Management of exposed, infected implant-based breast reconstruction and strategies for salvage.

INTRODUCTION: Complications of implant-based breast reconstruction are rare but mastectomy flap necrosis and peri-implant infection are the most frequent and remain an important cause of early implant failure. This study aimed to compare the results of three different management strategies employed to deal with these complications at our institution. PATIENTS AND METHODS: A consecutive series of 71 infected/exposed prostheses in 68 patients over a 20-year period were analysed. Management strategies included explantation and delayed reconstruction, implant salvage and explantation and immediate autologous reconstruction. RESULTS: Only 19 of 45 (42%), managed with implant removal, went on to delayed reconstruction. Methods of delayed reconstruction were distributed equally between implant-only, implant and autologous tissue and autologous-only reconstructions. The implant was successfully salvaged in nine cases, but reducing the implant size or introducing new tissue as a flap increased the success from 45% to 53%. Three patients with infected implant-only breast reconstruction underwent explantation and immediate conversion to autologous-only reconstructions. CONCLUSIONS: All the three interventions reviewed here have their place in the management of infected implant-based breast reconstructions. It is noteworthy that following implant removal, the likelihood of the patient proceeding to delayed reconstruction of any kind is similar to the likelihood of successful salvage (42% vs. 45%). This study population had high numbers of exposed implants in irradiated fields. Reducing implant size or introducing new tissue in the form of a flap increases the chances of successful implant salvage. In the presence of mild infection, removal of exposed/infected implants and immediate conversion to an autologous-only reconstruction can prove to be successful.

Oncoplastic breast surgery: a review and systematic approach.

Oncoplastic breast surgery (OBS) is relatively new, but has made rapid progress from its tentative steps of infancy in the 1990s. The recent Milanese Consensus Conference on Breast Conservation concluded that, firstly, oncoplastic techniques are warranted to allow wide excision and clear margins without compromising cosmesis. Secondly, such surgery is ideally performed at the same time as oncological excision. Whilst technically more challenging than standard breast conserving therapy (BCT), OBS is well proven, if not yet widely practised, both oncologically and aesthetically and a review of the available techniques is perhaps timely. The roots of breast conserving therapy can be traced to the 1930s, actually due to advances made in radiotherapy, and the last 20 years have seen it become firmly established. This review aims to summarise the key historical developments and latest innovations in OBS. Not only are our patients, who expect not only safe cancer treatment but a satisfactory aesthetic outcome, increasingly informed and demanding, but longer follow up has stimulated surgeons to improve outcomes. In many cases, particularly with ptosis and macromastia, the cancer can be treated, usually with wider excision margins, simultaneously improving the aesthetic appearance. Present at the birth of OBS, the Institut Curie has continued to introduce innovative techniques over the last two decades and a systematic approach, comprising nine basic techniques, has evolved to allow high quality treatment of any and all breast cancers suitable for OBS.

Lateral mammaplasty reconstruction after surgery for breast cancer.

BACKGROUND: Up to 60 per cent of cancers develop laterally in the breast and breast-conserving surgery frequently produces superolateral nipple-areolar complex (NAC) distortion aggravated by postoperative irradiation. Correction is technically demanding and the outcomes are variable. Lateral mammaplasty may allow wider excision margins and prevent such deformities. METHODS: This was a review of 86 consecutive patients who had lateral mammaplasty: combined wide tumour excision with NAC repositioning on a reliable dermoglandular pedicle. Simultaneous axillary surgery was performed via a separate or combined incision. Aesthetic outcomes were assessed. RESULTS: The median age of the women was 54 (range 29-75) years; 55 (64 per cent) had palpable tumours and 73 (85 per cent) underwent simultaneous axillary surgery. Median radiological and histological tumour sizes were 29.8 and 33.6 mm, respectively, and median weight of excised tumour was 150 g. Two patients required haematoma evacuation. Eleven women required revisional surgery for involved or close margins. Aesthetic outcomes were excellent or good in 93 per cent. CONCLUSION: Lateral mammaplasty produced clear margins in 87 per cent of women. It is an option when a deformity is anticipated after breast-conserving surgery, and is particularly valuable when neoadjuvant chemotherapy has downgraded a large tumour.

[Secondary breast reconstruction using exclusive lipofilling]. / Reconstruction mammaire secondaire par lipomodelage exclusif.

Lipofilling is usually performed in breast surgery for treatment of aesthetics sequelae after breast conserving surgery or correction after breast reconstruction by prothesis or musculocutaneous flaps. We present a case of a patient where exclusive lipofilling breast reconstruction has been successfully performed. Aesthetic result is assessed by the patient and the surgeon as very satisfactory after one year of follow-up. This technology not much used in this present indication have important advantages in terms of tolerance or morbidness but the long-term results depend on not controlled factors such as volumetric cast iron or fatty resorption. Further studies are necessary to define the patients will be able to benefit from this technology and to assess the modalities of follow-up but also to measure evenly practicability, stability of reconstruction and its evolution in time. However, aesthetic result and contentment of the patient allow us to envisage the broadcasting of this technology of mammary reconstruction for selected patients.

[Nipple and areola reconstruction by tattooing, "F" and "Z" flaps]. / La reconstruction de la plaque aréolo-mamelonnaire par tatouage, lambeaux << F >> et << Z >>

Nipple and areola reconstruction is very important in the evaluation of the quality of breast reconstruction. It can be done during the primary or secondary breast reconstruction or later. We have performed the techniques of nipple reconstruction routinely since 1992. Under local anesthesia during a second operative time or general anesthesia during breast reconstruction, the local "F" and "Z" skin flaps and tattooing grant a quality result in the wound and the long-term projection. They are easily reproduced, rapid and as there is no graft the choice of the incisions grants a good tolerance. Complications are rare and it is always possible to use other techniques in case of poor result. We also present the main techniques of nipple and areola reconstruction with their advantages and limits.

[Partial reconstruction after conservative treatment for breast cancer: classification of sequelae and treatment options]. / Séquelles esthétiques du traitement conservateur des cancers du sein: une classification pour les reconstructions après tumorectomie.

Most patients presenting with breast cancer are treated by breast conserving treatment (BCT). Some of these patients present with poor cosmetic results and ask for partial breast reconstruction. These reconstructions following BCT are presenting more frequently to plastic surgeons as a difficult management problem. We have defined and published a classification of the different cosmetic sequelae (CS) after BCT into three types. This classification helps to analyse these complex deformities aggravated by radiotherapy. Furthermore, our classification helps to choose between the different surgical techniques and propose the optimal option for their surgical correction. Our initial publications reported 35 and 85 patients: we have currently operated more than 150 cases of CS after BCT. Type-1 CS are defined by an asymmetry between the two breasts, with no distortion or deformity of the radiated breast. Type-2 CS are those with an obvious breast deformity, that can be corrected with a partial reconstruction of the breast. Type-3 CS are those with such a deformity that only a mastectomy with total reconstruction of the breast can be performed. Most of the patients present with type-2 CS, but are reluctant to undergo what they feel is a major reconstructive procedure: in a initial prospective series of 85 patients operated for CS after BCT, 48 (56.5%) had type-1 CS, 33 patients (38.8%) type-2 CS and four patients (4.7%) type-3 CS. Type-1 patients should be managed essentially by contralateral symmetrizing procedures. One should limit any surgery on the radiated breast, as a mammoplasty or an augmentation is at high risk of complications. Type-2 is the most difficult to manage and requires all the surgical armamentarium of breast reconstructive surgery. The insetting of a myocutaneous flap is often necessary and autologous fat grafting is a promising tool in selected cases. Type-3 CS requires mastectomy and immediate reconstruction with a myocutaneous flap. The major development though in the past 10 years has been the development of oncoplastic techniques at the time of the original tumour removal, in order to avoid most of type 2 and type 3 deformities. This paper reaffirms the validity of the Cosmetic Sequelae classification as a simple, practical guide for breast reconstructive surgeons. It discusses the various choices of reconstructive procedures available, the importance of "preventing" these CS and defining the role of the plastic surgeon in the management of these patients.

[Evaluation of asymetric implants in breast cancer]. / Evaluation des prothèses asymétriques en reconstruction mammaire.

Since more than twenty years, methods of breast reconstruction using implants have continued to evolve in order to improve their aesthetic results. Shapes and materials of these implants have also evolved to obtain contours similar to that of the natural opposite breast. Therefore it can be considered that the use of asymmetric implants is the last step in implant technology before using made to measure implants. Asymmetric implants allow obtaining different contours in harmony to the different breast shapes according to the side, left or right, of the reconstructed breast which maximise the naturalness of the result. Such implants have an axis directed towards the exterior and lower part of the chest wall, are wider than high with a thinner part on their inner edge and a concave rear side moulding the curves of the chest wall. In our own experience, we placed more than 500 asymmetric implants. When analysing retrospectively the medical records of 156 patients, no distinctive features were observed when compared to symmetric classic implants in easiness in the surgical procedure or in complications except a slightly higher rate of seroma formation. When compared to usual implants the main benefits of asymmetric implants are: to offer a wider breadth, to slope down gently on their upper and inner sides according to their concave rear side, and therefore to better match subtle curves of a normal breast. Moreover such contours allow a distribution of the volume which fit better to the usual natural breast configuration of patients who underwent surgery for breast carcinoma. At last, such implants are easy to place and a very low rate of secondary rotation has been observed. In summary, for all these reasons, asymmetric implants, can be considered to be the class one in the choice of implants for breast reconstruction after breast surgery.

[Evaluation of asymmetric implants in breast augmentation surgery]. / Evaluation des prothèses asymétriques dans la chirurgie mammaire d'augmentation.

Since more than 30 years, the quality of breast implants has continued to evolve in order to improve the aesthetic results of prosthetic augmentation. Shapes and materials of these implants have also evolved to obtain stronger and more reliable prostheses almost similar to the natural breast. Therefore it can be considered that the use of asymmetric implants is the last step in implant technology before using made to measure implants. Asymmetric implants allow obtaining different contours in harmony to the different breast shapes capable to reproduce faithfully, in all dimensions, the anatomy of the female breast, including the differences between each side which maximise the naturalness of the result. Such implants have an axis directed towards the exterior and lower part of the chest wall, are wider than high with a thinner part on their inner edge and a concave rear side moulding the curves of the chest wall. In our own experience, we placed between 2002 and 2004, asymmetric implants in 100 patients. Such implants were easy to place and no secondary rotation was observed. The control of secondary displacements even in case of prosthesis change seems to be linked to their concave rear side, roughness and asymmetry. When analysing retrospectively the medical records, no distinctive features were observed when compared to symmetric classic implants in easiness in the surgical procedure or in complications except a slightly higher rate of seroma formation. However asymmetric implants are less appropriate in case of major breast ptosis, patients being unsatisfied by the "too natural" breast shape. Moreover a high risk of secondary rotation seems to be real in such cases. In summary, for all these reasons, asymmetric implants, are gradually considered to be a first-rank choice for implants in breast augmentation cosmetic surgery.
