Mastectomy and immediate reconstruction of 122 breasts were performed in 109 patients in close collaboration between plastic surgeons and general surgeons. In 56 patients reconstruction was performed using tissue expanders including 13 bilateral operations, 29 patients had a latissimus dorsi myocutaneous flap and 24 a free transverse rectus abdominis myocutaneous flap. There were 27 postoperative local complications in 122 reconstructions (22%), in five the reconstruction was lost. Only patients clinically in stage I were considered for reconstruction. After histopathological staging 27 patients received systemic treatment and 10 local radiotherapy as well. There was no complication during systemic therapy related to reconstruction. In 10 cases local radiotherapy was performed in full, with a delay of four weeks in one patient and a need for correction of the radiation field during treatment in one patient.
