Key clinical point: In patients with breast cancer (BC), premastectomy radiotherapy (PreMRT) followed by mastectomy and immediate breast reconstruction (IMBR) is feasible, safe, and shortens the time required for breast reconstruction.
Major finding: At a median follow-up of 29.7 months, there were no complete flap losses, locoregional recurrences, distant metastases, or deaths in the 48 patients who completed mastectomy with IMBR. Patients could undergo mastectomy with IMBR as early as 3 weeks (median 23 days) after completing radiotherapy. No grade 3-4 radiotherapy-related toxic effect or discontinuation of radiotherapy was reported.
Study details: The study enrolled 49 patients with T0-T3, N0-N3b, M0 BC from the phase 2 SAPHIRE trial who received PreMRT and were randomly assigned to receive hypofractionated or conventionally fractionated regional nodal irradiation, followed by mastectomy and IMBR.
Disclosures: This study was supported by the National Cancer Institute of the US National Institutes of Health and others. Five authors declared receiving grants from or having other ties with various sources.
