Abstract
Introduction Breast reconstruction with autologous tissue is a state-of-the art procedure. Several patient-related factors have been identified with regard to the safety and efficacy of these reconstructions. The presented study investigates the impact of prereconstruction radiation on outcomes of deep inferior epigastric perforator (DIEP) free-flap breast reconstructions using largest database available in Europe. Materials and Methods Between 2011 and 2019, 3926 female patients underwent 4577 DIEP flap breast reconstructions in 22 different German breast cancer centers. The cases were divided into a no-radiation (NR) and a radiation (R) group, according to radiation status before reconstruction. Groups were compared with regard to surgical complications and free-flap outcome. Results Overall, there was no significant difference between the groups regarding the rate of total flap loss [1.9% (NR) vs 2.1% (R), P = 0.743], partial flap loss [0.9% (NR) vs 1.5 (R), P = 0.069], and revision surgery [vascular revision: 4.4% (NR) vs 4.1% (R), P = 0.686; wound revision: 7.6% (NR) vs 9.4% (R), P = 0.122]. However, the patients had a significantly higher risk of developing wound healing disturbances at the recipient site [1.2% (NR) vs 2.1% (R), P = 0.035] and showed significantly longer hospitalization {8 [SD, 8.4 (NR)] vs 9 [SD, 15.4 {R}] days, P = 0.006} after prereconstruction radiation. Conclusions Our findings suggest that DIEP flap reconstruction after radiation therapy is feasible. Women with a history of radiation therapy should, however, be informed in detail about the higher risk for wound healing disturbances at the recipient site.
