Background
Variation in rates of breast reconstruction after mastectomy has raised concerns about the quality of decisions about reconstruction. We sought to evaluate patient decision making about reconstruction, using a validated measure of knowledge and preferences related to reconstruction.
Methods
A cross-sectional survey of early-stage breast cancer survivors from four university medical centers was conducted. The survey included measures of knowledge about specific reconstruction facts, personal goals and concerns, and involvement in decision making. A multivariable linear regression model of characteristics associated with knowledge and a logistic regression model of factors associated with having reconstruction were developed.
Results
84 patients participated (59% response rate). Participants answered 37.9% of knowledge questions correctly. Higher education (beta 15%, p=0.003) and having reconstruction (beta 21%, p<0.0001) were associated with higher knowledge. The goals “use your own tissue to make a breast” (OR 1.53, 95% CI 1.15, 2.05) and “wake up after mastectomy with reconstruction underway” (OR 1.66, 95% CI 1.30, 2.12) were associated with reconstruction. The goal “avoid putting foreign material in your body” was associated with no reconstruction (OR 0.64, 95% CI 0.48, 0.86). Most patients reported they mainly made the decision or made the decision with the doctor equally (93%, 95%CI 85-97%), and that their degree of involvement was about right (85%, 95%CI 75-91%).
Conclusion
Women treated with mastectomy in this study were not well-informed about breast reconstruction. Treatments were associated with patients' goals and concerns, however, and patients were highly involved in their decisions. Knowledge deficits suggest that breast cancer patients would benefit from interventions to support their decision making.
