Implication

Cohort study reveals increased complications between 3 and 12 months post-radiation in autologous breast reconstruction, indicating reconstruction before 3 months is safe.

Key Points

To evaluate the association between the timing of delayed autologous breast reconstruction following postmastectomy radiation therapy and the risk of postoperative complications.
Retrospective cohort study using data from the Truven Health MarketScan Research Databases from 2009 to 2016 (N=1,039).
Patients underwent mastectomy, postmastectomy radiation therapy (PMRT), and delayed autologous breast reconstruction categorized into intervals: 0–3, 3–6, 6–12, 12–24, and >24 months.
Multivariable models evaluated associations between reconstruction timing and key measures of postoperative morbidity.
The overall complication rate was 39.4%, with wound complications occurring in 13.3% and additional flap requirements occurring in 11.3% of patients (peaking at 14.0% in the 3–6 month window).
Multivariable analysis identified significantly higher risks of any complication at 3–6 months (OR: 3.04, p < 0.001), 6–12 months (OR: 2.66, p < 0.001), and 12–24 months (OR: 2.13, p = 0.001) compared with 0–3 months.
Complication rates for reconstructions performed after 24 months did not differ significantly from those under 3 months (p > 0.05), though wound complications were lowest after 24 months (OR: 0.34, p = 0.035).
