Breast Implant Associated-Anaplastic Large Cell Lymphoma (BIA-ALCL) - Letter to Health Care Providers

February 6, 2019
Dear Health Care Providers of the following specialties:
  • Radiology
  • Pathology
  • Plastic Surgery
  • Cosmetic Surgery
  • General Surgery
  • Internal Medicine
  • Obstetrics/Gynecology
  • Oncology
  • General Practice/Family Practice
  • Nurse Practitioners
  • Physician's Assistants
  • Emergency Medicine
The Food and Drug Administration (FDA) wants to increase awareness about an association between all breast implants, regardless of filling or texture, and Breast Implant Associated- Anaplastic Large Cell Lymphoma (BIA-ALCL). The FDA received reports indicating that patients with breast implants have an increased risk of developing this disease within the scar capsule adjacent to the implant.
We want all healthcare providers to be aware of BIA-ALCL, particularly in patients with new swelling, lumps, or pain around breast implants, to expedite diagnosis of this malignancy. We are also asking health care providers to report to the FDA cases of BIA-ALCL in patients with breast implants. This includes reporting individual cases as well as rates you may have experienced during your practice.

BACKGROUND 

BIA-ALCL is a type of lymphoma and is not a cancer of the breast tissue. When breast implants are placed in the body, they are inserted behind the breast tissue or under the chest muscle. Over time, a fibrous scar called a capsule develops around the implant, separating it from the rest of the breast. In patients with breast implants, reported cases of BIA-ALCL were generally found adjacent to the implant itself and contained within the fibrous capsule.
A significant body of medical literature has been published since the FDA's 2011 report on BIA-ALCL, including additional case histories and comprehensive reviews of the natural history and long-term outcomes of BIA-ALCL. Current literature reports various estimates for the incidence of BIA-ALCL. These estimated incidence rates range from a high of 1 per 3,817 patients to a low estimate of 1 in 30,000 (Clemens et al, 2017; Loch-Wilkinson et al, 2017; De Boer et al, 2018). While the majority of patients who develop BIA-ALCL have had textured implants, and most cases reported in the literature describe individuals who have had textured implants, there have been reports of BIA-ALCL in patients with smooth-surfaced implants and many reports do not include the surface texture of the implant at the time of diagnosis.   
As of the latest medical device reports (MDRs) update, the FDA has received a total of 660 MDRs of BIA-ALCL. The FDA has carefully reviewed the 660 MDRs to remove duplicate reports and to control for MDRs in which a BIA-ALCL diagnosis was confirmed by: a physician, positive pathology/cytology test results, or positive for biomarker CD30 and negative for biomarker ALK. The FDA's additional data analysis identified 457 unique MDRs for BIA-ALCL, including the death of nine patients which may be attributable to BIA-ALCL. However, it is important to note that at the time of diagnosis, patients may have their original breast implants or they may have had one or more replacements.
While the MDR reports provide information regarding the implant at the time of BIA-ALCL diagnosis, they do not typically give information about a patient's history of breast implants. Additional cases have been identified through the FDA's contact with other regulatory authorities, scientific experts, and breast implant manufacturers. Recent journal articles explore possible risk factors for developing BIA-ALCL, including the methods used to create the textured surface and the role of biofilm. Additionally, most of the published information about treatment describes removal of the implant and the capsule surrounding the implant, and in some patients, treatment with chemotherapy and radiation.
Though the number of identified cases of BIA-ALCL is small compared to the estimated 1.5 million patients who receive breast implants worldwide every year, confirmed data and published information reviewed to date suggests that patients with breast implants have an increased risk of BIA-ALCL.

RECOMMENDATIONS

In most of the cases reported to the FDA, patients were diagnosed with BIA-ALCL when they sought medical treatment for implant-related symptoms such as pain, lumps, swelling, or asymmetry that developed after their initial surgical sites were fully healed. These symptoms were due to collection of fluid (seroma), or masses surrounding the breast implant. Examination of the fluid and capsule surrounding the breast implant led to the BIA-ALCL diagnosis.
Therefore, the FDA is recommending that health care providers:
  • Prior to implantation, provide all patients with the breast implant manufacturer's labeling, including the patient-specific labeling, as well as other educational material prior, and make sure they are aware of the benefits and risks of the different types of implants. Most confirmed cases of BIA-ALCL have occurred in patients with textured surface implants, although there are known cases in patients with only smooth-surface breast implants.
  • Consider the possibility of BIA-ALCL when treating a patient with late onset, peri-implant seroma. In some cases, patients presented with a mass or masses adjacent to the breast implant. If you have a patient with suspected BIA-ALCL, refer the individual's case to a multidisciplinary team for evaluation.
  • Collect fresh seroma fluid and representative portions of the capsule and send for pathology tests to rule out BIA-ALCL. Diagnostic evaluation should include cytological evaluation of seroma fluid or mass with Wright Giemsa stained smears and cell block immunohistochemistry/flow cytometry testing for cluster of differentiation (CD30) and Anaplastic Lymphoma Kinase (ALK) markers.
  • Develop an individualized treatment plan in coordination with the patient's multi-disciplinary care team. Consider current clinical practice guidelines, such as those from the Plastic Surgery Foundation or the National Comprehensive Cancer Network (NCCN) when choosing your treatment approach.
  • Report all confirmed cases of BIA-ALCL in individuals with breast implants to MedWatch, the FDA Safety Information and Adverse Event Reporting program.
    • Health care personnel employed by facilities that are subject to FDA's user facility reporting requirements should follow the reporting procedures established by their facilities. Prompt reporting of adverse events can help the FDA identify and better understand the risks associated with medical devices. In some cases, the FDA may contact you for additional information. The FDA will keep the identities of the reporter and the patient confidential.
  • Submit case reports of BIA-ALCL to the Patient Registry and Outcomes For breast Implants and anaplastic large cell Lymphoma etiology and Epidemiology (PROFILE) Registry to contribute to a better understanding of the causes and treatments of BIA-ALCL. 

FDA ACTIONS

The FDA continues to actively work alongside the American Society of Plastic Surgeons (ASPS), international regulatory agencies and other experts in the clinical and scientific communities to evaluate all available information to understand the nature and possible factors contributing to BIA-ALCL in patients with breast implants.
The FDA will keep the public informed as significant new information becomes available.
