Epidemiological Profile in Portugal of Breast Implant-Associated Anaplastic Large Cell Lymphoma: A Cross-Sectional Study.

Abstract

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a rare T-cell neoplasm that is predominantly associated with the use of textured implants. Recently, several countries have tried to clarify their epidemiological profile of BIA-ALCL. This study aims to estimate the number of cases of BIA-ALCL in Portugal and to describe the pattern of use of breast implants at a national level. This is a cross-sectional study including 57 healthcare institutions - 29 public hospitals and 28 private institutions. Each department of Plastic, Reconstructive and Aesthetic Surgery was asked to provide information concerning the main manufacturer(s) and respective device texture of the breast implants used, and to report the number of registered cases of BIA-ALCL. In our study sample, the response rate was 58%. In our sample, most hospitals reported using textured breast implants from Mentor (45.45%), Allergan (42.42%) and Polytech (39.39%). Only one private institution referred using smooth-coated implants from Mentor and Motiva. Despite several hospitals reporting late-onset seromas, there was only one confirmed case of BIA-ALCL after proper investigation with immunohistochemistry and histological procedures. BIA-ALCL may represent a shift for surgeons regarding selection of implant type. Smooth-coated implants or autologous tissue represent adequate alternatives that could surpass the risks associated with textured devices. In the future, the creation of a national patient registry and proper recognition of BIA-ALCL by plastic surgeons could be useful tools to clarify the impact of the disease nationally and to mitigate potential risk factors.
