Use of textured breast implants for postmastectomy reconstruction led to a small but significant increase in breast cancer recurrence as compared with smooth-surface implants, a retrospective study from South Korea showed.
Overall, 4% of 650 women had some form of disease recurrence during a median follow-up of 52 months after receiving breast implants. The 5-year locoregional recurrence-free survival (LRRFS) rate was 95.9% among women who received textured implants and 97.8% in those who had smooth implants, a nonsignificant difference, reported Sa Ik Bang, MD, PhD, of Sungkyunkwan University and Samsung Medical Center in Seoul, and colleagues.
As shown in their study online in JAMA Surgery, the 5-year disease-free survival (DFS) rate was significantly lower with textured implants: 93.3% vs 97.8%.
In a Kaplan-Meier survival analysis, LRRFS did not differ by implant surface type, but DFS remained significantly lower in the textured-implant group at 3, 4, and 5 years.
