Abstract Breast augmentation is a common aesthetic surgery, and there are two major surgical methods for breast implant delivery: the finger method and the plastic film method. There are advantages and disadvantages for each method, and we have developed a pre-lubricated polypropylene (PP) injector that might be the most suitable device for delivering breast implants. By covering the interior surface of the injector with the hydrophilic coating, the friction coefficient was significantly reduced when sliding a silicone sled against the pre-lubricated PP injector. In order to confirm the pre-lubricated PP injector would not damage the breast implant, fatigue testing was performed and the result showed the injector did not cause rupture or microleakage of the breast implant. In addition, the cell viability result demonstrated the pre-lubricated PP injector was biocompatible. In addition, the pre-lubricated PP injector provides a small incision site and stability during breast implant delivery. Our results provided evidence that the pre-lubricated PP injector is a smooth and safe method for breast implant delivery.

Abstract Background Granzyme B (GrB) is a serine protease secreted, along with pore-forming perforin, by cytotoxic lymphocytes to mediate apoptosis in target cells. GrB has been detected in tumor cells associated with systemic and breast implant–associated anaplastic large cell lymphoma (BIA-ALCL) but its potential use for detection of early BIA-ALCL has not been fully investigated. Objectives Prompted by the increased incidence of BIA-ALCL, the aim of this study was to assess GrB as a new biomarker to detect early disease in malignant seromas and to better understand the nature of the neoplastic cell. Methods A Human XL Cytokine Discovery Magnetic Luminex 45-plex Fixed Panel Performance Assay was used to compare cytokine levels in cell culture supernatants of BIA-ALCL and other T-cell lymphomas, as well as malignant and benign seromas surrounding breast implants. Immunohistochemistry was employed to localize GrB to cells in seromas and capsular infiltrates. Results Differences in GrB concentrations between malignant and benign seromas were significant (P < 0.001). GrB was found in and around apoptotic tumor cells, suggesting that the protease may be involved in tumor cell death. Conclusions GrB is a useful marker for early detection of malignant seromas and to identify tumor cells in seromas and capsular infiltrates. Because there is an overlap between the lowest concentrations of soluble GrB in malignant seromas and the highest concentrations of GrB in benign seromas, it is recommended that GrB be used only as part of a panel of biomarkers for the screening and early detection of BIA-ALCL.

Abstract Introduction Peri-implant fluid more than 6 months from surgery is a known complication of breast surgery.Differential diagnosis includes infection, inflammation,implant rupture and haematoma.Other than infection raised no concern until the identification of Breast Implant Associated Anaplastic Large Cell Lymphoma(BIA-ALCL). Method Retrospective electronic data collection for women 18 years or older who met the following inclusion criteria:(a)oncoplastic and/or cosmetic reconstructive surgery with placement of implant(b)peri-implant fluid collection after 6-36 months. Results In total,17 women with implants with a mean age of 56 years were included in the study.The mean time between reconstructive surgery and the peri-implant fluid collection was 23 months.The median peri-implant fluid collection size was 143 ml.14 of the 17 peri-implant fluid collections were benign.12 of 14 had polyurethane-coated textured implants.4 of the 17 were BIA-ALCL. Conclusions The current literature suggests that late peri-implant seromas arise from friction as the implant moves within the cavity and that this friction is increased with textured rather than smooth implants.In our unit 12/14 of the benign collections appeared in reconstructions with polyurethane implants.Furthermore,BIA-ALCL should always be considered in this situation and aspirate should be sent for cytology.Is this change in polyurethane implants a new entity?

Breast implantation either for cosmetic or reconstructive e purposes is one of the most common procedures performed in plastic surgery. Biofilm infection is hypothesised to be involved in the development of both capsular contracture and anaplastic large cell lymphoma (ALCL). Capsular contracture is one of the principal reasons for breast revision surgery and is characterised by the tightening and hardening of the capsule surrounding the implant, and ALCL is an indolent lymphoma found only in women with textured implants. We describe the types of breast implants available with regard to their surface characteristics of surface area and roughness and how this might contribute to capsular contracture and/or biofilm formation. The pathogenesis of capsular contracture is thought to be due to biofilm formation on the implant, which results in on-going inflammation. We describe the current research into breast implant associated ALCL and how implant properties may affect its pathogenesis, with ALCL only occurring in women with textured implants.

Large Cell Lymphoma

Breast implant-associated anaplastic large cell lymphoma (ALCL) is a recently recognized type of T-cell lymphoma that can develop following breast implants, with morphologic and immunophenotypic features indistinguishable from those of ALK-negative ALCL. Here we report a case of a 58-year-old woman with a history of subglandular silicone implants placed for bilateral breast augmentation 25 years ago, who presented with bilateral breast pain and was found to have bilateral Baker Grade III capsular contracture, and heterogenous fluid collection centered near the left third costochondral articulation, a suspicious left chest wall lesion, and left axillary lymphadenopathy on imaging. A left axillary lymph node core biopsy and an aspiration of the fluid were performed, and no malignant cells were identified. The patient underwent bilateral removal of breast implants and total capsulectomies. Microscopic examination of the capsule surrounding the left breast implant revealed large pleomorphic tumor cells in a fibrinous exudate. By immunohistochemistry, the tumor cells were found to be positive for CD3 (subset), CD4, CD7, CD30 (strong and uniform), and CD43, and negative for CD2, CD5, CD8, and ALK1, supporting the diagnosis of breast implant-associated ALCL. No lymphoma cells were identified in the right breast capsule, confirmed by CD30 stain. Breast implant-associated ALCL is a very rare disease that can develop many years after breast implant placement. Proper evaluation with breast imaging and pathologic workup is essential to confirm the diagnosis in suspected cases. Our case highlights that adequate sampling is important in the investigation of patients with suspected breast implant-associated ALCL.

Large Cell Lymphoma

Abstract Background Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is an emerging cancer that has been linked to the use of textured devices. The recent increase in number and frequency of cases has led to worldwide regulatory action. Objectives The authors aimed to longitudinally study BIA-ALCL in Australia since the index case was first reported in 2007. Methods Confirmed historical cases were collected and then prospectively analyzed from October 2015 to May 2019. Clinical and implant exposure data were determined and compared with company sales data for 4 devices to generate implant-specific risk. Results A total 104 cases of BIA-ALCL were diagnosed in Australia with exposure to 149 unique breast implants. The mean age of patients was 48.2 years (range, 22.4-78.5 years). They had an average time from implantation to diagnosis of 6.8 years. A total 51.7% of implants utilized in this cohort were Allergan Biocell devices. The indication for implant usage was for primary cosmetic augmentation in 70%, post-breast cancer reconstruction in 23%, and following weight loss/pregnancy in 7%. The majority of women presented with early (stage 1) disease (87.5%). The risk for developing BIA-ALCL ranged from 1 in 1947 sales (95% confidence interval = 1199-3406) for Silimed Polyurethane devices to 1 in 36,730 (95% confidence interval = 12,568-178,107) for Siltex imprinted textured devices. Conclusions Implants with higher surface area/texture seem to be more associated with BIA-ALCL in Australia. Recent regulatory action to suspend, cancel, or recall some of these higher risk devices is supported by these findings. Level of Evidence: 2
