Abstract
Background:
The association between textured implants and breast implant–associated anaplastic large cell lymphoma (BIA-ALCL) is well established, but the risk of BIA-ALCL in patients with transient exposure to a textured tissue expander (TE) is not as well documented. The aim of this study was to assess the incidence and risk of BIA-ALCL in patients with temporary exposure to a textured TE with subsequent smooth implant placement.
Methods:
This single-institution retrospective cohort study included all female patients who underwent two-stage breast reconstruction with placement of a textured TE from 1995 to 2016 with subsequent exchange to a smooth permanent implant. Primary outcome of interest was development of BIA-ALCL. Patients with exposure to textured implants were excluded. Follow-up was determined by last documented visit. The authors calculated summary statistics for exposure time and follow-up intervals.
Results:
Overall, 3310 patients had temporary exposure to a textured TE with exchange to a smooth implant, totaling 5201 textured TEs. Average textured TE exposure time was 6.7 months (median, 5.8 months). Average follow-up was 6.8 years (median, 6.3 years), ranging from 3.7 months to 18 years. No cases of BIA-ALCL were identified.
Conclusions:
As no cases of BIA-ALCL were identified, the risk of BIA-ALCL with short exposure to textured TEs is likely lower than the risk from exposure to permanent textured implants. Although longer follow-up is needed, these results can help counsel patients with previous exposure to textured TEs who are concerned about their risk of BIA-ALCL and can contribute to discussions on potential continued utility of textured TEs.
