Why the Micromort Concept Falls Short in Breast Implant-Associated Anaplastic Large Cell Lymphoma (BIA-ALCL) Risk Analysis

BIA-ALCL Epidemiological Findings From a Retrospective Study of 248 Cases Extracted From Relevant Case Reports and Series: A Systematic Review

BACKGROUND

The epidemiologic picture of breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is unclear, with no high-level evidence, because only case reports and series are available.

OBJECTIVES

The aim of this study was to update knowledge on BIA-ALCL epidemiology by utilizing all available data through a systematic review of scientific literature.

METHODS

A search on PubMed, Scopus, and Web of Science was conducted between October 2021 and April 2022. Out of the 2799 available records, 114 pertinent articles were selected, featuring 248 BIA-ALCL cases which were retrospectively analyzed by means of descriptive statistics, incidence rate (IR), Kaplan-Meier survival curves, and Pearson correlation coefficients.

RESULTS

The United States, the Netherlands, Italy, and Australia were the countries reporting the most cases. The mean age at first implantation was 42 years, and the mean age at diagnosis was 53 years. Aesthetic indications were the reason for 52% of cases, and reconstruction for 48%; macrotextured surface was linked to 73.8% of cases, and seroma to 83%. Total follow-up was 492 months, and mean event-free time (EFT) to BIA-ALCL development was 129 months. The IR was 96 new cases/1,000 women per year after first implantation, and was directly correlated to the number of replacements. EFT was directly correlated to the number of replacements, implant rupture, and capsule contracture, and was inversely associated with patients' age at first implantation and to BRACA1/2 and TP53 mutations.

CONCLUSIONS

Macrotextured implant use in older patients and in patients with BRCA1/2 and TP53 mutations should be reconsidered, because this is associated with earlier disease onset. Implant replacement of asymptomatic, risk-stratified patients can be indicated due to its protective role against BIA-ALCL, reducing IR and risk, while increasing the EFT.

Clinical recommendations for diagnosis and treatment according to current updated knowledge on BIA-ALCL

Shared strategies and correct information are essential to guide physicians in the management of such an uncommon disease as Breast Implant-Associated Anaplastic Large Cell Lymphoma (BIA-ALCL). A systematic review of the literature was performed to collect the most relevant evidence on BIA-ALCL reported cases. A panel of multidisciplinary experts discussed the scientific evidence on BIA-ALCL, and updated consensus recommendations were developed through the Delphi process. The lastest reported Italian incidence of BIA-ALCL is 3.5 per 100.000 implanted patients (95% CI, 1.36 to 5.78), and the disease counts over 1216 cases worldwide as of June 2022. The most common presentation symptom is a late onset seroma followed by a palpable breast mass. In the event of a suspicious case, ultrasound-guided fine-needle aspiration should be the first step in evaluation, followed by cytologic and immunohistochemical examination. In patients with confirmed diagnosis of BIA-ALCL confined to the capsule, the en-bloc capsulectomy should be performed, followed by immediate autologous reconstruction, while delayed reconstruction applies for disseminate disease or radically unresectable tumor. Nevertheless, a multidisciplinary team approach is essential for the correct management of this pathology.

Management of Asymptomatic Patients With Textured Breast Implants: A Survey Analysis of Members of The Aesthetic Society

BACKGROUND

The management of breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) has been well established. However, there is minimal data and significant variability in the management of asymptomatic textured implant (ATI) patients.

OBJECTIVES

The purpose of this study was to survey members of The Aesthetic Society on management of ATI patients in order to understand trends in practice patterns.

METHODS

Members of The Aesthetic Society were queried via an electronic survey regarding management of ATI patients. Anonymous responses were collected by QualtricsXM (SAP, Walldorf, Germany) survey software. Descriptive statistics were used to examine the data, reported as frequencies. All analyses were performed with IBM SPSS Statistics 26.

RESULTS

The survey was sent to 2149 active and candidate members of The Aesthetic Society with a total of 470 responses (21.87% response rate). For ATI patients presenting with concerns regarding BIA-ALCL risk, 88.8% of respondents educate the patient with clinical follow-up and/or imaging. The other 11.2% of surgeons recommend implant removal with variability in capsulectomy technique. For ATI patients requesting surgery, 42.5% of respondents educate the patient with clinical follow-up and/or imaging. The majority of surgeons (57.6%) recommend removal of the implant, with 30% recommending total capsulectomies.

CONCLUSIONS

There is considerable variability in how members of The Aesthetic Society manage ATI patients who request surgery. Future regulatory agency and professional society collaborative efforts should continue to aim for generation of high-level scientific data to aid in the counseling and management of ATI patients.

Evaluating the Necessity of Capsulectomy in Cases of Textured Breast Implant Replacement

BACKGROUND

Capsulectomy has traditionally been recommended as a treatment for capsular contracture after breast augmentation. With the advent of breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL), and the Food and Drug Administration's decision to ban Biocell textured devices, this operation has taken on new importance. This review was undertaken to better inform clinical recommendations for women with textured devices.

METHODS

An electronic search was performed using PubMed to identify all the available literature on the subject of capsulectomy and open capsulotomy (the alternative treatment).

RESULTS

Fifty-seven articles on this topic were identified. Capsulectomy was widely recommended for treatment of capsular contracture, although many authors recommended leaving thin capsular tissue behind in the absence of symptoms. En bloc resection was recommended only for women with a diagnosis of BIA-ALCL. No information supported a prophylactic role for capsulectomy in asymptomatic women with textured breast implants who are concerned regarding their future risk of BIA-ALCL. Routine pathologic examination in asymptomatic patients was not supported.

DISCUSSION

Capsulectomy adds substantially to the surgical risk, discomfort, recovery time, and expense. Implant removal or replacement without a simultaneous capsulectomy is atraumatic and poses negligible risk.

CONCLUSIONS

Capsulectomy introduces additional morbidity and is not mandatory for asymptomatic patients. Implant removal or exchange for smooth implants without a capsulectomy may be an acceptable choice for many women who do not demonstrate capsular pathology. However, any symptoms or surgical findings suggesting pathology warrant a capsulectomy. En bloc resections are reserved for patients diagnosed with BIA-ALCL.

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.
