Effect of Patient Age on Outcomes in Breast Reconstruction: Results from a Multicenter Prospective Study

Although >40% of new breast cancer diagnoses in the US are in older women, few studies have assessed the outcomes of post-mastectomy reconstruction in this population. Our objective was to evaluate age effects on postoperative complications and patient-reported outcomes in women undergoing breast reconstruction, and to investigate whether age effects differ between reconstructive procedure types.

Eligible patients in the Mastectomy Reconstruction Outcomes Consortium study from 11 institutions (57 providers) in North America were analyzed. Two-year complications and patient-reported outcomes via BREAST-Q domains were compared across younger (younger than 45 years), middle-aged (45 to 60 years), and older (older than 60 years) women. Mixed-effects regression models were used, controlling for a range of demographic and clinical covariates.

A total of 1,531 patients were studied: 494 younger, 803 middle-aged, and 234 older. Age was not a significant predictor of complications. For sexual well-being 2 years post-reconstruction, older women reported 4.25 (p = 0.04) higher mean scores with implant procedures, and 10.39 (p < 0.01) higher mean scores with autologous procedures compared with younger women. No age effect was seen with implant procedures with regard to physical and psychosocial well-being; however, older women who underwent autologous procedures reported 6.07 (p < 0.01) higher physical, and 8.21 (p < 0.01) higher psychosocial well-being scores than younger women.

Age did not significantly affect complication rates. Older women demonstrated higher sexual well-being for both procedures, and better satisfaction and physical and psychosocial well-being than younger women with autologous procedures. Post-mastectomy reconstruction is a viable option for older patients, with risks and benefits comparable with those in younger women.
