Complications and Long-term Satisfaction in Autologous vs. Implant-Based Breast Reconstruction

The study is conducted at the Medical University of Graz and has been approved by the responsible ethics' committee (EK: 32-235 ex 19/20). The study includes female breast cancer patients who underwent elective breast reconstruction at one of the participating departments between April 2020 and April 2023. Written informed consent was obtained from all individual study participants enrolled. Exclusion criteria is defined as: * Missing or insufficient information * combination of reconstruction techniques on the same breast * reconstruction procedures with insufficient number of cases * inability to fully understand study procedures and to provide informed consent Data were first collected retrospectively from the clinical data management programs using surgical reports, outpatient charts, and physicians' letters. Personal data such as patient age, concomitant diseases, nicotine abuse, anticoagulation status, previous oncological therapy and surgery, etc. were acquired. Furthermore, surgery-related data (site and type of reconstruction, size and location of implant/tissue expander, intraoperative complications) and data on the postoperative course (early and late complications, revision surgeries, number of total surgeries required, etc.) were acquired. The five-level modified Clavien-Dindo classification is used to objectively classify postoperative complications, to allow further comparisons between treatment options, different time periods and correlations to health-related quality of life. Postoperative changes in health-related quality of life are measured using the BREAST-Q questionnaire, an effective and reliable patient-reported outcome measure in breast reconstruction.
