Breast reconstruction patterns from a Swedish nation-wide survey

Abstract

ObjectivesThe overall aim of the Swedish Breast Reconstruction Outcome Study was to investigate national long-term outcomes after mastectomy with or without breast reconstruction. The current report evaluates breast reconstruction (BR) patterns in Sweden over time. Materials and methodsThis is a cross-sectional, registry-based study where all women operated with mastectomy 2000, 2005, 2010 were identified (N = 5853). Geographical differences in type of BR were investigated using heatmaps. Distribution of continuous variables were compared using the Mann-Whitney U test, categorical variables were compared using the chi-square test. ResultsMean age at survey was 69 years (SD=±11.4) and response rate was 50%, responders were on average six years younger than the non-responders and had a more favourable tumor stage (both p < 0.01). Of the 2904 responders, 31% (895/2904) had received a BR: implant-based in 58% (516/895)autologous in 31% (281/895). BR was immediate in 20% (176/895) and delayed in 80% (719/895) women.Women with BR were on average one year older, more often had a normal BMI, reported to be married or had a partner, had a higher educational level and a higher annual income when compared to those without BR (all p < 0.001). The independent factors of not receiving BR were older age and given radiotherapy. ConclusionsTo our knowledge, this is the first national long-term follow-up study on women undergoing mastectomy with and without BR. Around 30% of the survey responders have had a BR with a significant geographical variation highlighting the importance of information, availability and standardisation of indications for BR.
