Abstract
Purpose
To improve shared decision making, clinical- and patient-reported outcomes between immediate implant-based and autologous breast reconstruction followed by postmastectomy radiotherapy (PMRT) were compared.
Methods
All women with in situ and/or invasive breast cancer who underwent skin sparing mastectomy with immediate breast reconstruction (IBR) (autologous- or implant based, one- or two staged) followed by PMRT in the Utrecht region between 2012 and 2016 were selected from the Netherlands Cancer Registry, of which 112 (59%) agreed to participate. The primary outcome was reconstruction failure after the start of radiotherapy, and secondary outcomes were patient-reported outcomes measured with BREAST-Q.
Results
109 patients underwent skin-sparing mastectomy, of which 29 (27%) underwent immediate autologous reconstruction and 80 (73%) received immediate implant-based reconstruction. After PMRT, reconstruction failure occurred in 17 patients (21%) with implant-based reconstruction, while no failure was seen in the autologous group (p = 0.04). Mean patient-reported ‘Satisfaction with Breasts’ (50.9 vs. 63.7, p = 0.001) and ‘Sexual Well-being’ (46.0 vs. 55.5, p = 0.037) were lower after implant-based reconstruction compared to autologous reconstruction. Thirteen patients with autologous flaps underwent surgical cosmetic corrections compared to ten patients in the implant group (45 vs. 13%, p = 0.001). IBR and PMRT in this study resulted in a high rate of severe capsular contraction in implant-based reconstruction (16.9%) and fibrosis in autologous reconstruction (13.8%).
Conclusions
Patients treated with PMRT and one or two stage immediate implant-based reconstruction were at greater risk of develo** reconstruction failure and were less satisfied when compared to one or two stage immediate autologous reconstruction. Since fairly high complication rates in both reconstruction methods after PMRT are observed, it raises the question whether immediate breast reconstruction should be considered at all when PMRT is indicated. Patients considering or potential candidates for IBR should be informed about the consequences of PMRT and especially when opting for autologous reconstruction one should possibly perform reconstruction in a secondary setting.
