Current Progress in Breast Implant-Associated Anaplastic Large Cell Lymphoma

Breast Implant Surgery: The Importance of Informed Health Care Decisions and Outcome Monitoring

Breast implant surgery is a popular, globally performed, and frequently requested cosmetic and reconstructive surgical procedure. Breast implant surgery can cause implant-associated systemic symptoms and types of implant-associated cancers, so it is vital to monitor patient outcomes. Most patients who undergo breast implant surgery do not experience health problems. However, patients who do experience health problems as a result of breast implant surgery form a unique patient population. When plastic and aesthetic surgeons, nurses, and other healthcare providers are knowledgeable and experienced in recognizing and treating patients with health problems related to breast implant surgery, the health outcomes of this patient population improve. This article aims to promote informed decision-making and increase patient safety by providing information about the health problems associated with breast implant surgery. This article also highlights recent safety announcements and updates from the United States Food and Drug Administration (FDA). Ensuring the safety of patients undergoing breast implant surgery is a responsibility shared by plastic and aesthetic surgeons, nurses, and other healthcare providers; the general medical community; breast implant manufacturers; and the FDA. These entities must collaborate and coordinate as a united group to accomplish this important goal. The nursing profession can contribute to these collaborative efforts by serving as professional liaisons to these entities and advocating for continued collaborative efforts to increase the safety of patients who have undergone breast implant surgery.

A case of BIA-ALCL in which postoperative chest wall recurrence was highly suspected: the third reported case of BIA-ALCL in Japan

BACKGROUND

Breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL) is a rare malignancy. Many cases of BIA-ALCL are identified based on the presence of late-onset effusion and/or masses. Importantly, the United States Food and Drug Administration noted that in all cases diagnosed in patients with textured implants, the patients either had a history of mixed implantation of smooth and textured devices or no clinical history was supplied for review. In Japan, the first case of BIA-ALCL was reported in 2019, and we encountered the third case in Japan in December 2021. There have been a total of five cases of BIA-ALCL previously reported at Japanese academic conferences (Japan Oncoplastic Breast Surgery Society. http://jopbs.umin.jp/medical/index.html ), of which only the first case has been published. Unlike the first case, this patient had clinical features that were highly suggestive of the postoperative chest wall recurrence of breast cancer, with a mass and rash on the skin.

CASE PRESENTATION

The patient was a 45-year-old woman who had undergone breast reconstruction after breast cancer surgery of the right breast 8 years previously. The patient presented with a mass and skin rash inside the inframammary area, and we suspected a damaged silicone breast implant (SBI) or chest wall recurrence. We examined the mass by a core needle biopsy and made a pathological diagnosis of BIA-ALCL. Imaging findings suggested internal thoracic lymph node swelling and lymphoma infiltration beyond the capsule but no metastatic lesions (cStage III). After en bloc resection of the SBI and lymphoma, adjuvant systemic therapy was performed.

CONCLUSION

We encountered the third case of BIA-ALCL in Japan. This was a case with clinically advanced stage of disease; however, the BIA-ALCL was found to be in remission.

Safety and Efficacy of the Sientra Silicone Gel Round and Shaped Breast Implants: 6-Year Results of the U.S. Postapproval Study

BACKGROUND

After approval of Sientra silicone gel breast implants in March of 2012, the U.S. Food and Drug Administration required completion of a 10-year U.S. postapproval study. The authors present results from the first 6 years of this study.

METHODS

An ongoing, open-label, prospective, multicenter study is being conducted to evaluate the long-term clinical performance of Sientra implants in patients undergoing breast augmentation, reconstruction, and revision in the postmarket environment. Enrollment of 5197 patients (10,327 implants) was completed on March 6, 2015 (4046 primary augmentation, 895 revision-augmentation, 149 primary reconstruction, and 107 revision-reconstruction). Analyses were conducted at year 6 (database lock: January 24, 2022).

RESULTS

Across all cohorts who received an implant, the Kaplan-Meier risk of investigator-reported Baker grade III/IV capsular contracture was 4.1% (3.9% with submuscular placement and 6.75%with subglandular placement), the risk of reoperation was 11.6%, and the risk of implant removal was 7.8% (5.9% with implant replacement and 2.0% without replacement). The primary reason (>50%) for reoperation was aesthetic (eg, style/size change). The Kaplan-Meier risk of rupture, calculated for patients who underwent explantation or MRI for rupture evaluation, was 5.8%. Overall, 82.6% of patients were highly satisfied/happy with their implant. No cases of breast implant-associated anaplastic large cell lymphoma were reported.

CONCLUSION

Six-year results of the postapproval study were consistent with the 10-year core study and provide additional evidence in a large data set supporting the comprehensive safety and effectiveness profile of the Sientra implants.

Breast implant surface topography triggers a chronic-like inflammatory response

Breast implants are extensively employed for both reconstructive and esthetic purposes. However, the safety of breast implants with textured surfaces has been questioned, owing to a potential correlation with anaplastic large-cell lymphoma and the recurrence of breast cancer. This study investigates the immune response elicited by different prosthetic surfaces, focusing on the comparison between macrotextured and microtextured breast implants. Through the analysis of intraoperatively harvested periprosthetic fluids and cell culture experiments on surface replicas, we demonstrate that macrotextured surfaces elicit a more pronounced chronic-like activation of leucocytes and an increased release of inflammatory cytokines, in contrast to microtextured surfaces. In addition, in vitro fluorescent imaging of leucocytes revealed an accumulation of lymphocytes within the cavities of the macrotextured surfaces, indicating that the physical entrapment of these cells may contribute to their activation. These findings suggest that the topography of implant surfaces plays a significant role in promoting a chronic-like inflammatory environment, which could be a contributing factor in the development of lymphomas associated with a wide range of implantable devices.

From Case Reports to Molecular Insight: Examining the Outcomes and Underlying Mechanisms of Squamous Cell Carcinoma in Breast Implant Patients-A Systematic Review

There is extensive coverage in the existing literature on implant-associated lymphomas like anaplastic large-cell lymphoma, but breast implant-associated squamous cell carcinoma (BIA-SCC) has received limited scholarly attention since its first case in 1992. Thus, this study aims to conduct a qualitative synthesis focused on the underexplored association between breast implants and BIA-SCC. A systematic review was conducted utilizing the PubMed, Web of Science, and Cochrane databases to identify all currently reported cases of BIA-SCC. Additionally, a literature review was performed to identify potential biochemical mechanisms that could lead to BIA-SCC. Studies were vetted for quality using the NIH quality assessment tool. From an initial pool of 246 papers, 11 met the quality criteria for inclusion, examining a total of 14 patients aged between 40 and 81 years. BIA-SCC was found in a diverse range of implants, including those with smooth and textured surfaces, as well as those filled with saline and silicone. The condition notably manifested a proclivity for aggressive clinical progression, as evidenced by a mortality rate approximating 21.4% within a post-diagnostic interval of six months. Our literature review reveals that chronic inflammation, driven by various external factors such as pathogens and implants, can initiate carcinogenesis through epigenetic modifications and immune system alterations. This includes effects from exosomes and macrophage polarization, showcasing potential pathways for the pathogenesis of BIA-SCC. The study highlights the pressing need for further investigation into BIA-SCC, a subject hitherto inadequately addressed in the academic sphere. This necessitates the urgency for early screening and intervention to improve postoperative outcomes. While the review is confined by its reliance on case reports and series, it serves as a valuable reference for future research endeavors.

BIA-ALCL in patients with genetic predisposition for breast cancer: our experience and a review of the literature

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is an emerging non-Hodgkin's lymphoma that occurs exclusively in patients with breast implants. The estimated risk of developing BIA-ALCL from exposure to breast implants is largely based on approximations about patients at risk. There is a growing body of evidence regarding the presence of specific germline mutations in patients developing BIA-ALCL, rising interest regarding possible markers of genetic predisposition to this type of lymphoma. The present paper focuses attention on BIA-ALCL in women with a genetic predisposition for breast cancer. We report our experience at the European Institute of Oncology, Milan, Italy, describing a case of BIA-ALCL in a BRCA1 mutation carrier who developed BIA-ALCL 5 years after implant-based post mastectomy reconstruction. She was treated successfully with an en-bloc capsulectomy. Additionally, we review the available literature on inherited genetic factors predisposing to the development of BIA-ALCL. In patients with genetic predisposition to breast cancer (mainly TP53 and BRCA1/2 germline mutations), BIA-ALCL prevalence seems to be higher and time to onset appears to be shorter in comparison to the general population. These high-risk patients are already included in close follow-up programs allowing the diagnosis of early-stage BIA-ALCL. For this reason, we do not believe that a different approach should be followed for postoperative surveillance.

Practice Trends in the Management of Asymptomatic Breast Reconstruction Patients with Textured Implants: A Survey Analysis

Despite the increasing prevalence of breast implant associated anaplastic large cell lymphoma, there remains a paucity of literature guiding management of asymptomatic patients with textured breast implants. This risk can be anxiety provoking in breast reconstruction patients given their history of cancer or increased future risk. The purpose of this study is to evaluate current practice trends when managing the concerned asymptomatic patient following textured implant-based breast reconstruction.

Methods

An electronic survey was distributed to members of the American Society of Plastic Surgeons, regarding management of asymptomatic breast reconstruction patients with textured devices. Anonymous responses were collected, and statistical analysis was performed.

Results

A total of 304 responses were received. Of respondents, 237 (92%) have managed asymptomatic patients with textured devices. Historically, the overwhelming majority (89%) used textured devices; however, only 25% report current use. Regarding management of asymptomatic breast reconstruction patients, 87% recommend conservative management, while 13% recommend surgical management. When surgery is performed, 16.3% of respondents elected for implant exchange, 33.8% recommended implant exchange with partial capsulectomy, and 49.8% elected for implant exchange with total capsulectomy. Evaluation of practice patterns based on demographics demonstrated statistically significant differences in current use of textured devices and management of acellular dermal matrix.

Conclusions

Despite decreased current use, there is a significant population of asymptomatic breast reconstruction patients with a history of textured devices concerned for risk of breast implant associated anaplastic large cell lymphoma. This survey demonstrates ongoing variability in surgeon recommendations regarding conservative and surgical management of these patients and the need for continued development of evidence-based guidelines.

Breast Implant-Associated Tumors

In addition to anaplastic large T-cell lymphomas (BIA-ALCL), other implant-related tumors have been described for some years. Squamous cell carcinoma (SSC) and B-cell lymphomas occurred in very rare cases. The unexplained pathogenesis as well as the unclear individual risk profile is an ongoing source of uncertainty for patients and physicians. The pathogenesis of the tumors is still largely not understood. While BIA-ALCL occurs more frequently with textured breast implants, other tumors were also observed with smooth implants and at other implant sites. Multiple potential mechanisms are discussed. It is suspected that the etiology of a chronic inflammatory response and subsequently immunostimulation is multifactorial and appears to play a key role in the malignant transformation. Since there are currently no sufficiently valid data for a specific risk assessment, this must be done with caution. This article presents the incidence, pathogenesis, as well as the level of evidence according to the current state of knowledge, and evaluates and discusses the current literature.

Breast Implant-Associated Anaplastic Large Cell Lymphoma

Pathologic staging including assessment of margins is essential for the proper management of patients with breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL). As most patients present with effusion, cytologic examination with immunohistochemistry and/or flow cytometry immunophenotyping are essential for diagnosis. Upon a diagnosis of BIA-ALCL, en bloc resection is recommended. When a tumor mass is not identified, a systematic approach to fixation and sampling of the capsule, followed by pathologic staging and assessment of margins, is essential. Cure is likely when lymphoma is contained within the en bloc resection and margins are negative. Incomplete resection or positive margins require a multidisciplinary team assessment for adjuvant therapy.

First Case Report of Breast Implant Associated-Anaplastic Large Cell Lymphoma from India: Are We Ready?

Breast implant associated-anaplastic large cell lymphoma (BIA-ALCL) has become a hot topic in recent plastic surgery and oncology forum. Its cases have been on the rise since its first emergence more than two decades ago. This condition is less known and management guidelines are still evolving. BIA-ALCL was seen recently with a classical presentation in one of our patients, who underwent immediate reconstruction with a macro-textured silicone implant following breast cancer surgery. We want to add the first case report from India to the global information database. There are still unanswered questions in its management, and we wish to highlight the same to make way for further research. With the rise in aesthetic and reconstructive implant surgeries, the knowledge of BIA-ALCL must expand among oncologists, radiologists, and pathologists for early identification and treatment for better patient outcomes.

The Role of Microorganisms in the Development of Breast Implant-Associated Anaplastic Large Cell Lymphoma

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a variant of anaplastic large cell lymphoma (ALCL) associated with textured-surface silicone breast implants. Since first being described in 1997, over 1100 cases have been currently reported worldwide. A causal relationship between BIA-ALCL and textured implants has been established in epidemiological studies, but a multifactorial process is likely to be involved in the pathogenesis of BIA-ALCL. However, pathophysiologic mechanisms remain unclear. One of the hypotheses that could explain the link between textured implants and BIA-ALCL consists in the greater tendency of bacterial biofilm in colonizing the surface of textured implants compared to smooth implants, and the resulting chronic inflammation which, in predisposed individuals, may lead to tumorigenesis. This review summarizes the existing evidence on the role of micro-organisms and rough surface implants in the development of BIA-ALCL. It also provides insights into the most updated clinical practice knowledge about BIA-ALCL, from clinical presentation and investigation to treatment and outcomes.

Reverse strategy to locally advanced breast implant-associated anaplastic large cell lymphoma: A case report

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a rare T-cell lymphoma associated with textured breast implants. The most common presentation is a periprosthetic seroma that occurs at least 1 year after an aesthetic or reconstructive implantation, and in these cases, the surgical treatment seems to be successful. More rarely, BIA-ALCL presents with locally advanced mass-formed disease and a related regional lymph node involvement. In all these cases with worse prognosis, a multidisciplinary approach is required, including adjuvant chemotherapy, radiation therapy, and surgery. We present a clinical case of a 49-year-old woman who developed on the left side of the breast a mass-formed stage 3 BIA-ALCL 15 years after a bilateral breast augmentation with textured silicone implant. Our multidisciplinary team (MDT) scheduled the patient for a "reverse-strategy" sequential approach consisting of induction chemotherapy, hematopoietic stem cell mobilization, and harvest followed by autologous stem cell transplant (ASCT). After 100 days from the stem cell transplant, the patient showed a complete pathologic response and was a candidate for radical surgery. She underwent removal of both implants with total en bloc capsulectomy. On the left site, the periprosthetic mass was also en bloc removed. We did not perform any axillary dissection. Our surgical and hemato-oncological teams followed the patient every 3 months, and no local or systemic recurrences were observed 24 months after surgery. This case report has demonstrated the effectiveness of neoadjuvant chemotherapy as part of a "reverse strategy" in selected cases of advanced-stage BIA-ALCL in which it was not possible to perform an immediate radical surgery. Furthermore, in our case, the de-escalation strategy adopted permitted a less demolitic surgery with good functional and aesthetic results.

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.

Clinical Manifestations and Surgical Management of Breast Implant-Associated Anaplastic Large Cell Lymphoma: Beyond the NCCN Guidelines

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is an uncommon peripheral T cell lymphoma arising in response to textured-surface breast implants. Frequently, BIA-ALCL is indolent and typically presents with peri-implant swelling after breast reconstruction or cosmetic augmentation. However, patients can present with an invasive breast or chest wall mass, palpable lymphadenopathy, or metastatic disease. The current literature is limited regarding surgical recommendations for patients with a more aggressive presentation of BIA-ALCL. This report aims to review the various clinical manifestations of BIA-ALCL, including the more advanced and less frequently encountered presentations, with an emphasis on a multidisciplinary approach, with early involvement of a surgical oncologist.

Silicon breast implants’ texture affecting bacterial biofilm formation

Introduction/Objective. The most important etiologic factors for both, capsular contracture (CC) and breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is subclinical infection, defined as a response of an organism on presence of biofilm on the implant surface. The aim of this research was to examine the possibility of biofilm formation of four different bacteria (Staphylococcus epidermidis, Staphylococcus aureus, Pseudomonas aeruginosa, and Ralstonia picketti) on three differently textured silicone breast implants (Siltex, Mentor, pore size 70?150 ?m; MESMORsensitive, Polytech, pore size 50?900 ?m; and SilkSurface, Motiva pores 13 ?m) in vitro. Methods. Samples of silicone breast implant capsules (sized 1 ? 1 cm) were divided into three groups according to texture. After sterilization, 30 samples in every group were contaminated with 100 ?l of examined bacterial broth, followed by incubation which led to biofilm formation. For testing the capability of biofilm formation, modified technique with microtitar plates described by Stepanovic? was used. Results. All four examined bacteria (Staphylococcus epidermidis, Staphylococcus aureus, Pseudomonas aeruginosa, and Ralstonia picketti) form more biofilm on implants with pore sizes 50?900 ?m compared to implants with pore size 70?150 ?m and those with 13 ?m. Statistical significance was found in biofilm formation on implants with pores 70?150 ?m compared to implants with pores 13 ?m. The only exception was P. aeuruginosa which did not show significant difference in biofilm formation on implants 70?150 ?m and 13 ?m. Conclusion. Silicone breast implants with micro and nanotexture should be chosen in order to prevent biofilm formation and possible consequent complications.
