In a study reported in JAMA Surgery, Hanson et al found no difference in long-term satisfaction with breasts among women with early breast cancer who underwent breast-conserving surgery with radiation therapy vs mastectomy and breast reconstruction without radiation therapy. Women who underwent mastectomy and reconstruction without radiotherapy reported poorer psychosocial and sexual well-being.
The study used data from the Texas Cancer Registry for women diagnosed with stage 0 to II breast cancer and treated with breast-conserving surgery or mastectomy and reconstruction between 2006 and 2008. A total of 1,616 patients, including 980 who had undergone breast-conserving surgery and 636 who had undergone mastectomy and reconstruction, were mailed a survey between March 2017 and April 2018.
The primary outcome measure was satisfaction with breasts, assessed with the BREAST-Q patient-reported outcome instrument. Physical well-being, psychosocial well-being, and sexual well-being were assessed using BREAST-Q; health utility was assessed using the EuroQol Health-Related Quality of Life 5-Dimension/3-Level questionnaire; and treatment decision regret was assessed using the Decisional Regret Scale. Scores were transformed to a 0 to 100 scale (higher = better), with clinically significant difference defined as an absolute difference of at least 8 points.
Among 647 women who responded to the survey (40.0%), 356 had undergone breast-conserving surgery and 291 had undergone mastectomy with reconstruction. Median age was 53 years (range = 23–85 years) and median time from diagnosis to survey was 10.3 years (range = 8.4–12.5 years).
On multivariate analysis, no significant difference between the breast-conserving surgery group vs the mastectomy with reconstruction group was observed for satisfaction with breasts (effect size = 2.71, 95% confidence interval [CI] = –2.45 to 7.88, P = .30).
Similarly, no significant differences between the breast-conserving surgery group vs the mastectomy with reconstruction group were observed for physical well-being (effect size = –1.80, 95% CI = –5.65 to 2.05, P = .36), health utility (effect size = –0.003, 95% CI = –0.03 to 0.03, P = .83) or decisional regret (effect size = 1.32, 95% CI = –3.77 to 6.40, P = .61).
Compared with the breast-conserving surgery group, the mastectomy with reconstruction group reported significantly poorer psychosocial well-being (effect size = –8.61, 95% CI = –13.26 to –3.95, P < .001) and sexual well-being (effect size = –10.68, 95% CI = –16.60 to –4.76, P < .001).
The investigators concluded: “The findings support equivalence of breast-conserving surgery with [radiotherapy] and mastectomy and reconstruction without [radiotherapy] with regard to breast satisfaction and physical well-being. However, breast-conserving surgery with [radiotherapy] was associated with clinically meaningful improvements in psychosocial and sexual well-being. These findings may help inform preference-sensitive decision-making for women with early-stage breast cancer.”
