Is breast implant-associated anaplastic large cell lymphoma a hazard of breast implant surgery?

Anaplastic lymphoma associated with breast implants-Early diagnosis and treatment

Anaplastic large cell lymphoma associated with breast implants is a relatively new disease that deserves attention from the academic community. Brazil figures as one of the protagonists in plastic surgery, however publications are insufficient and very few cases are reported in comparison to other countries. It is a disease with excellent prognosis when diagnosed early and treated effectively, but for this to happen, it is essential that health care professionals and the patient understand its pathology. We reported two cases in a small town during a short period of time. In both cases reported by this study, the patients presented late seroma, associated with pain as a clinical presentation, at 13 and 9 years after the placement of silicone implants with textured polyurethane surfaces. After the procedure, the patients were screened for cancer. Further research with more robust samples is still needed to fully determine the risks and benefits of using textured versus smooth implants.

The evaluation of the delayed swollen breast in patients with a history of breast implants

Breast implants, whether placed for reconstructive or cosmetic purposes, are rarely lifetime devices. Rupture, resulting from compromised implant shell integrity, and capsular contracture caused by constriction of the specialized scar tissue that normally forms around breast implants, have long been recognized, and remain the leading causes of implant failure. It is apparent, however, that women with breast implants may also experience delayed breast swelling due to a range of etiologic factors. While a majority of delayed seromas associated with breast implants have a benign etiology, this presentation cannot be ignored without an adequate workup as malignancies such as breast implant associated anaplastic large cell lymphoma (BIA-ALCL), breast implant associated diffuse large B-cell lymphoma (BIA-DLBCL), and breast implant associated squamous cell carcinoma (BIA-SCC) can have a similar clinical presentation. Since these malignancies occur with sufficient frequency, and with sometimes lethal consequences, their existence must be recognized, and an appropriate diagnostic approach implemented. A multidisciplinary team that involves a plastic surgeon, radiologist, pathologist, and, as required, surgical and medical oncologists can expedite judicious care. Herein we review and further characterize conditions that can lead to delayed swelling around breast implants.

Current Understanding of Breast Implant-Associated Anaplastic Large Cell Lymphoma

Every year, breast implants are inserted worldwide for reconstructive or aesthetic reasons. Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a rather uncommon type of T cell lymphoma that is positive for the CD30 biomarker. Despite being far more common than other primary breast lymphomas, BIA-ALCL has a very low incidence. Textured types of implants have been linked to almost all cases. The majority of patients have a favorable prognosis after the removal of implants and capsules. Nevertheless, the chance of a fatal outcome is higher with capsular invasion and tumor bulk. Although the exact cause of BIA-ALCL is unknown, it has been suggested that persistent infections or toxins related to the implants may play a role. Therefore, physicians must be aware of breast implants' rare but potentially significant side effects. Before surgery, patients with verified instances should be directed to a breast medical oncologist or lymphoma specialist for oncologic assessment. Total en-bloc capsulectomy, a surgical procedure that removes the implant and the surrounding capsule, is usually adequate. In other cases, a late diagnosis necessitates more invasive surgery and systemic therapies, which, while typically effective, have been linked to poor outcomes and even fatalities. Since it is a recently described entity and the "denominator" (i.e., the total number of breast implant procedures) is unknown, it is challenging to determine the risk of development. In this review, we hope to emphasize the elements of etiology, demography, clinical features, and current treatment approaches for BIA-ALCL. In doing so, we hope to increase the medical professional's knowledge of the recognition and treatment of BIA-ALCL.

2022 Practice Recommendation Updates From the World Consensus Conference on BIA-ALCL

BACKGROUND

Laboratory and clinical research on breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is rapidly evolving. Changes in standard of care and insights into best practice were recently presented at the 3rd World Consensus Conference on BIA-ALCL.

OBJECTIVES

The authors sought to provide practice recommendations from a consensus of experts, supplemented with a literature review regarding epidemiology, etiology, pathogenesis, diagnosis, treatment, socio-psychological aspects, and international authority guidance.

METHODS

A literature search of all manuscripts between 1997 and August 2021 for the above areas of BIA-ALCL was conducted with the PubMed database. Manuscripts in different languages, on non-human subjects, and/or discussing conditions separate from BIA-ALCL were excluded. The study was conducted employing the Delphi process, gathering 18 experts panelists and utilizing email-based questionnaires to record the level of agreement with each statement by applying a 5-point Likert Scale. Median response, interquartile range, and comments were employed to accept, reject, or revise each statement.

RESULTS

The literature search initially yielded 764 manuscripts, of which 405 were discarded. From the remaining 359, only 218 were included in the review and utilized to prepare 36 statements subdivided into 5 sections. After 1 round, panelists agreed on all criteria.

CONCLUSIONS

BIA-ALCL is uncommon and still largely underreported. Mandatory implant registries and actions by regulatory authorities are needed to better understand disease epidemiology and address initial lymphomagenesis and progression. Deviation from current diagnosis and treatment protocols can lead to disease recurrence, and research on breast implant risk factors provide insight to etiology.

ESSM Position Statement "Sexual Wellbeing After Gender Affirming Surgery"

Introduction

Much has been published on the surgical and functional results following Gender Affirming Surgery (‘GAS’) in trans individuals. Comprehensive results regarding sexual wellbeing following GAS, however, are generally lacking.

Aim

To review the impact of various GAS on sexual wellbeing in treatment seeking trans individuals, and provide a comprehensive list of clinical recommendations regarding the various surgical options of GAS on behalf of the European Society for Sexual Medicine.

Methods

The Medline, Cochrane Library and Embase databases were reviewed on the results of sexual wellbeing after GAS.

Main Outcomes Measure

The task force established consensus statements regarding the somatic and general requirements before GAS and of GAS: orchiectomy-only, vaginoplasty, breast augmentation, vocal feminization surgery, facial feminization surgery, mastectomy, removal of the female sexual organs, metaidoioplasty, and phalloplasty. Outcomes pertaining to sexual wellbeing- sexual satisfaction, sexual relationship, sexual response, sexual activity, enacted sexual script, sexuality, sexual function, genital function, quality of sex life and sexual pleasure- are provided for each statement separately.

Results

The present position paper provides clinicians with statements and recommendations for clinical practice, regarding GAS and their effects on sexual wellbeing in trans individuals. These data, are limited and may not be sufficient to make evidence-based recommendations for every surgical option. Findings regarding sexual wellbeing following GAS were mainly positive. There was no data on sexual wellbeing following orchiectomy-only, vocal feminization surgery, facial feminization surgery or the removal of the female sexual organs. The choice for GAS is dependent on patient preference, anatomy and health status, and the surgeon's skills. Trans individuals may benefit from studies focusing exclusively on the effects of GAS on sexual wellbeing.

Conclusion

The available evidence suggests positive results regarding sexual wellbeing following GAS. We advise more studies that underline the evidence regarding sexual wellbeing following GAS. This position statement may aid both clinicians and patients in decision-making process regarding the choice for GAS. Özer M, Toulabi SP, Fisher AD, et al.

Breast Implant-Associated Anaplastic Large Cell Lymphoma (BIA-ALCL): Review of Epidemiology and Prevalence Assessment in Europe

BACKGROUND

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) epidemiologic studies focus on incidence and risk estimates.

OBJECTIVES

The aim of this study was to perform a thorough literature review, and to provide an accurate estimate of BIA-ALCL prevalence in Europe.

METHODS

We searched PubMed, Web of Science, SCOPUS, and Google Scholar databases to identify publications reporting BIA-ALCL epidemiology. Research was conducted between November 2019 and August 2020. European prevalence was assessed as the ratio between pathology-confirmed cases and breast implant-bearing individuals. The Committee on Device Safety and Development (CDSD) collected data from national plastic surgery societies, health authorities, and disease-specific registries to calculate the numerator. The denominator was estimated by combining European demographic data with scientific reports.

RESULTS

Our research identified 507 articles: 106 were excluded for not being relevant to BIA-ALCL. From the remaining 401 articles, we selected 35 that discussed epidemiology and 12 reviews. The CDSD reported 420 cases in Europe, with an overall prevalence of 1:13,745 cases in the 28 member states of the European Union (EU-28). Countries where specific measures have been implemented to tackle BIA-ALCL account for 61% of the EU-28 population and actively reported 382 cases with an overall prevalence of 1:9121.

CONCLUSION

Countries where specific measures have been implemented show a higher prevalence of BIA-ALCL compared with the European mean, suggesting that these countries have improved the detection of the condition and reduced underreporting, which affects the numerator value. Other nations should adopt projections based on these measures to avoid underestimating how widespread BIA-ALCL is.

Microbial community compositions in breast implant biofilms associated with contracted capsules

Subclinical bacterial infections (biofilms) are strongly implicated in breast augmentation failure due to capsular contracture, and while these infections are generally ascribed to common skin commensals, this remains largely unsubstantiated through robust cultivation independent analyses. To determine capsule biofilm microbial community compositions, we employed amplicon sequencing of the 16S rRNA gene using DNA extracted from breast implant capsule samples. These cultivation independent analyses revealed that capsule associated biofilms are more diverse than canonical single-species infections, but have relatively low diversity (~ <100 species) compared to many host-associated microbial communities. In addition to taxa commonly associated with capsular contracture, the biofilms analyzed comprised a number of taxa that escaped detection in cultivation-dependent work. We have also isolated several key taxa identified through the culture-independent analyses. Together our analyses reveal that capsule biofilms are more diverse than cultivation studies suggest and can be heterogeneous within an individual capsule, between breasts of the same patient, across similar implant types, and over a range in severity of contracture. The complex nature of these communities requires further study across a broader suite of patients in addition to higher resolution analyses including metagenomics to better assess the fundamental role of microorganisms in capsular contracture.

Rare Cancer on the Rise: An Educational Review of Breast Implant-associated Anaplastic Large Cell Lymphoma

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a rare but increasingly important diagnosis as the incidence of breast implant placement, both elective and reconstructive, continues to rise. When detected and treated early, this indolent disease carries an excellent prognosis. However, because the clinical presentation is often nonspecific, it is crucial for radiologists to accurately identify the imaging findings associated with BIA-ALCL to facilitate a timely diagnosis. This article will provide radiologists with an overview of the diagnosis, imaging findings, and management of BIA-ALCL.

Silicone nipple discharge: A case report of an unusual presentation of breast implant rupture

INTRODUCTION

Breast implant rupture is a well-documented complication of breast implant surgery. Diagnosis of ruptured silicone implants can be difficult due to the lack of overt symptoms. This is the first reported case of a patient with silicone breast implant rupture presenting with clear nipple discharge and is presented in line with SCARCE 2018 Guidelines [1].

PRESENTATION OF CASE

A 45-year-old-female was referred to a breast surgeon with viscous clear nipple discharge, on a background of bilateral mastopexy-augmentation surgery 10 years prior. Imaging revealed extensive intraductal and free silicone causing significant stromal deformity secondary to breast implant rupture. Cytology of the nipple discharge was consistent with silicone gel. The patient was also found to have fibroadenoma without atypia in the right breast. She underwent an oncoplastic excision of free silicone and change of bilateral breast implants by a team of breast and plastic surgeons.

DISCUSSION

With breast implants being an increasingly common procedure worldwide, we can expect an increase in these unusual presentations. Clinicians and patients need to be aware of these in order to avoid an unnecessary delay in diagnosis.

CONCLUSION

Silicone implant rupture is a well-known complication and the rate of rupture increases over the life of the implant. Diagnosis of ruptured silicone implants is rare on clinical examination however remains an essential component of a doctor's examination of the patient and nipple discharge must be considered a symptom of rupture.

A Novel JAK1 Mutant Breast Implant-Associated Anaplastic Large Cell Lymphoma Patient-Derived Xenograft Fostering Pre-Clinical Discoveries

Breast implant-associated lymphoma (BIA-ALCL) has recently been recognized as an independent peripheral T-cell lymphoma (PTCL) entity. In this study, we generated the first BIA-ALCL patient-derived tumor xenograft (PDTX) model (IL89) and a matching continuous cell line (IL89_CL#3488) to discover potential vulnerabilities and druggable targets. We characterized IL89 and IL89_CL#3488, both phenotypically and genotypically, and demonstrated that they closely resemble the matching human primary lymphoma. The tumor content underwent significant enrichment along passages, as confirmed by the increased variant allele frequency (VAF) of mutations. Known aberrations (JAK1 and KMT2C) were identified, together with novel hits, including PDGFB, PDGFRA, and SETBP1. A deep sequencing approach allowed the detection of mutations below the Whole Exome Sequencing (WES) sensitivity threshold, including JAK1G1097D, in the primary sample. RNA sequencing confirmed the expression of a signature of differentially expressed genes in BIA-ALCL. Next, we tested IL89’s sensitivity to the JAK inhibitor ruxolitinib and observed a potent anti-tumor effect, both in vitro and in vivo. We also implemented a high-throughput drug screening approach to identify compounds associated with increased responses in the presence of ruxolitinib. In conclusion, these new IL89 BIA-ALCL models closely recapitulate the primary correspondent lymphoma and represent an informative platform for dissecting the molecular features of BIA-ALCL and performing pre-clinical drug discovery studies, fostering the development of new precision medicine approaches.

The Emerging Crisis of Stakeholders in Implant-based Augmentation Mammaplasty in Korea

BACKGROUND

Korea is no longer safe from the risk of breast implant-associated anaplastic large cell lymphoma (BIA-ALCL); the first reported case was a Korean woman in her 40s who had a 7-year-history of receiving an implant-based augmentation mammaplasty using a textured implant. We conducted this study to discuss the emerging crisis of stakeholders in implant-based augmentation mammaplasty and to propose a multi-disciplinary approach to early detection of its complications.

METHODS

We analyzed medical examination data that was collected from patients who visited us between August 12 and September 27, 2019. We evaluated a total of 114 women (n = 114) in the current study. They were evaluated for whether they were in healthy condition. Moreover, their baseline characteristics were also examined; these included age, gender, height (cm), weight (kg), duration since surgery (years), possession of a breast implant card, the site of surgical incision, side of symptoms and reasons for outpatient visit. Furthermore, the patients were also evaluated for their subjective awareness of the manufacturer, surface and shape of the breast implant. Potential complications include malrotation, folding, seroma, capsule thickening, upside-down rotation, rupture, capsule mass and breast mass.

RESULTS

A majority of the patients had a past history of receiving textured implants. The corresponding percentage was 78.95% (90/114) and 85.09% (97/114) based on their subjective awareness of a breast implant and sonographic findings, respectively. That is, it was slightly increased with the use of a breast ultrasound.

CONCLUSION

Here, we propose the following approaches. First, patient data should be prospectively collected. By tracking outcomes and complications of an implant-based augmentation mammaplasty, both high-quality care and patient safety can be ensured. Second, stakeholders in implant-based augmentation mammaplasty should collaborate with customers and regulatory authorities. Third, surgeons should consider applying imaging modalities for early detection of postoperative complications.

Granulomatous slack skin mycosis fungoides developing simultaneously with sarcoid-like lesions in a patient with repeated anabolic injections in the past?

We present a 32-year-old man with successful treatment and remission of mycosis fungoides of both axillae in 2016 after PUVA therapy and systemic and local administration of corticosteroids. Subsequently, in 2017, the patient also achieved remission of a T-cell CD 30 positive, ALK-1 negative large-cell lymphoma of a retroperitoneal and inguinal lymph node after chemotherapy and radiotherapy. One year later, in 2018, the patient presented to our clinic with progression of skin lesions in both axillary areas and the appearance of а tumor in the right gluteal region.Dermatological examination showed livid-to-erythematous, partly sclerotic plaques in the right inguinal area, cutis laxa-like plaque formations in the right axillary region with similar but less-developed changes in the left axillary fold, a solitary subcutaneous tumor formation affecting the entire right gluteal region, and enlarged, palpable lymph nodes in the right para-axillary area. Biopsies were obtained from an axillary lesion and the surgically removed axillary lymph nodes, and histological examination revealed changes of granulomatous slack skin in the axilla and reactive inflammatory changes in the lymph nodes. Histology of gluteal tissue showed a "foreign body" type of reaction with sarcoid-like features, where the patient in the past have been injected with anabolic and steroidal drugs. Herein we describe a patient with simultaneous occurrence of granulomatous slack skin type mycosis fungoides and a sarcoid-like reaction. The question remains open whether this represents the so-called sarcoidosis-lymphoma syndrome or, more likely, granulomatous slack skin MF associated with a sarcoid-like reaction of "foreign body" type. The possibility that disturbance of tissue homeostasis by incorporation of certain adjuvants within injections (for example) in the past might have been an inducer of cutaneous T cell lymphoma and sarcoidosis/sarcoid like lesions seems reasonable but also speculative.

A Rare Case of Breast Implant-Associated Diffuse Large B-Cell Lymphoma

This is a case of an elderly female who presented for follow-up ultrasound of the right breast after routine mammogram revealed a small benign mass. A subsequent ultrasound detected a small nodular mass that was described as benign in appearance. Although the patient was asymptomatic, a fine-needle biopsy was performed to rule out malignancy. Results from immunohistochemistry and FISH studies of the biopsy were positive for diffuse large B-cell lymphoma (DLBCL). The patient underwent surgery for lumpectomy and removal of breast implants. Intraoperative tissue samples were analyzed by pathology using both flow cytometry and microscopy, and results confirmed DLBCL. With total tumor resection and implant removal completed, the patient did not require additional treatments as the prognosis of DLBCL status post implant removal is excellent. She returned for follow-up six months later and has since had no signs of reoccurrence.

Cell of Origin and Immunologic Events in the Pathogenesis of Breast Implant-Associated Anaplastic Large-Cell Lymphoma

Breast implant–associated anaplastic large-cell lymphoma (BIA-ALCL) is a CD30-positive, anaplastic lymphoma kinase–negative T-cell lymphoma. Nearly all cases have been associated with textured implants. Most cases are of effusion-limited, indolent disease, with an excellent prognosis after implant and capsule removal. However, capsular invasion and tumor mass have a more aggressive course and a fatal outcome risk. This review summarizes the current knowledge on BIA-ALCL cell of origin and immunologic factors underlying its pathogenesis. Cytokine expression profiling of BIA-ALCL cell lines and clinical specimens reveals a predominantly type 17 helper T-cell (Th17)/Th1 signature, implicating this as its cell of origin. However, a Th2 allergic inflammatory response is suggested by the presence of IL-13, with infiltration of eosinophils and IgE-coated mast cells in clinical specimens of BIA-ALCL. The microenvironment-induced T-cell plasticity, a factor increasingly appreciated, may partially explain these divergent results. Mutations resulting in constitutive Janus kinase (JAK)–STAT activation have been detected and associated with BIA-ALCL pathogenesis in a small number of cases. One possible scenario is that an inflammatory microenvironment stimulates an immune response, followed by polyclonal expansion of Th17/Th1 cell subsets with release of inflammatory cytokines and chemokines and accumulation of seroma. JAK-STAT3 gain-of-function mutations within this pathway and others may subsequently lead to monoclonal T-cell proliferation and clinical BIA-ALCL. Current research suggests that therapies targeting JAK proteins warrant investigation in BIA-ALCL.
