Abstract
Background:
Weight gain is a common occurrence among breast cancer patients. Previous studies have shown an increase in weight is correlated with a greater risk of recurrence. The impact of autologous breast reconstruction versus implant-based reconstruction on BMI has not previously been analyzed.
Methods:
This was a single-center retrospective review of 506 patients who received breast reconstruction following mastectomy by a single surgeon between 2008-2017. Patients were categorized by autologous versus implant-based reconstruction. Follow-up data were reviewed for BMI, weight at diagnosis, and each year up to 10 years post-op. T-test analysis was performed to determine the effects of different breast reconstruction on change in BMI.
Results: For autologous reconstruction, the average percent BMI change from diagnosis to 6 months,1 year, 2 years, 3 years, 4 years, 5 years, and 10 years was 0.20%, 1.30%, 1.61%, 2.53%, 3.89%, 3.92%, and 7.56%, respectively. For implant-based reconstruction, the average percent BMI change from diagnosis BMI to 6 months,1 year, 2 years, 3 years, 4 years, 5 years, and 10 years was 1.49%, 2.24%, 3.59%. 3.44%, 3.00%, 4.60%, and 9.31%. For autologous reconstruction, the average weight change from diagnosis weight to 10 years were 11.93 pounds and for implant-based reconstruction it was 11.08 pounds.
Conclusion: Both autologous and implant-based reconstruction are associated with weight gain, on average 11 pounds by 10-years post-op. Patients should be counselled that breast reconstruction is associated with long-term weight gain, but is not dependent on type of breast reconstruction (autologous versus implant-based).
