Prospective Study of Psychosocial Outcomes of Having Contralateral Prophylactic Mastectomy Among Women With Nonhereditary Breast Cancer.

ABSTRACT: Purpose The incidence of contralateral prophylactic mastectomy (CPM) has continued to increase. We prospectively examined psychosocial outcomes before and up to 18 months after surgery in women who did or did not have CPM. Methods Women with unilateral, nonhereditary breast cancer completed questionnaires before and 1, 6, 12, and 18 months after surgery. Primary psychosocial measures were cancer worry and cancer-specific distress. Secondary measures were body image, quality of life (QOL), decisional satisfaction, and decisional regret. Results A total of 288 women (mean age, 56 years; 58% non-Hispanic white) provided questionnaire data, of whom 50 underwent CPM. Before surgery, women who subsequently received CPM had higher cancer distress ( P = .04), cancer worry ( P < .001), and body image concerns ( P < .001) than women who did not have CPM. In a multivariable repeated measures model adjusted for time, age, race/ethnicity, and stage, CPM was associated with more body image distress ( P < .001) and poorer QOL ( P = .02). There was a significant interaction between time point and CPM group for cancer worry ( Pinteraction < .001), suggesting that CPM patients had higher presurgery cancer worry, but their postsurgery worry decreased over time and was similar to the worry of patients who did not have CPM. QOL was similar between CPM groups before surgery but declined 1 month after surgery and remained lower than patients who did not have CPM after surgery ( Pinteraction = .05). Conclusion These results may facilitate informed discussions between women and their physicians regarding CPM. Fear and worry may be foremost concerns at the time surgical decisions are made, when women may not anticipate the adverse future effect of CPM on body image and QOL.

Project description:BACKGROUND:Contralateral prophylactic mastectomy may be unnecessary from an oncologic perspective; therefore, the debate persists about the value of contralateral prophylactic mastectomy in women with early-stage unilateral breast cancer. Given finite health care resources, this study aims to evaluate the cost of contralateral prophylactic mastectomy and breast reconstruction. METHODS:Women with unilateral breast cancer undergoing either unilateral mastectomy or unilateral mastectomy with contralateral prophylactic mastectomy and immediate breast reconstruction were selected from the Truven MarketScan databases between 2009 and 2013. Demographic and treatment data were recorded, and over an 18-month follow-up period, the treatment cost was tallied. A log-transformed linear model was used to compare cost between the groups. RESULTS:A total of 2343 women were identified who met our inclusion criteria, with 1295 undergoing unilateral mastectomy and 1048 undergoing contralateral prophylactic mastectomy. Complication rates within 18 months were similar for women undergoing unilateral mastectomy and contralateral prophylactic mastectomy (39 percent versus 42 percent; p = 0.17). Management with unilateral mastectomy with reconstruction required an adjusted cumulative mean cost of $33,557. Contralateral prophylactic mastectomy with reconstruction was an additional $11,872 in expenditure (p < 0.001). The cost of initial procedures (mean difference, $6467) and secondary procedures (mean difference, $2455) were the greatest contributors to cost. CONCLUSIONS:In women with unilateral breast cancer, contralateral prophylactic mastectomy with reconstruction is more costly. The increased monetary cost of contralateral prophylactic mastectomy may be offset by improved quality of life. However, this financial reality is an important consideration when ongoing efforts toward reimbursement reform may not pay for contralateral prophylactic mastectomy if outcomes data are not presented to justify this procedure.

Project description:ImportanceRates of contralateral prophylactic mastectomy (CPM) have markedly increased but we know little about the influence of surgeons on variability of the procedure in the community.ObjectiveTo quantify the influence of the attending surgeon on rates of CPM and clinician attitudes that explained it.Design, setting, and participantsIn this population-based survey study, we identified 7810 women with stages 0 to II breast cancer treated in 2013 to 2015 through the Surveillance, Epidemiology, and End Results registries of Georgia and Los Angeles County. Surveys were sent approximately 2 months after surgery. Surveys were also sent to 488 attending surgeons identified by the patients.Main outcomes and measuresWe conducted multilevel analyses to examine the impact of surgeon influence on variations in patient receipt of CPM using information from patient and surgeon surveys merged to Surveillance, Epidemiology, and End Results data.ResultsA total of 5080 women responded to the survey (70% response rate), and 377 surgeons responded (77% response rate). The mean (SD) age of responding women was 61.9 (11) years; 28% had an increased risk of second primary cancer, and 16% received CPM. Half of surgeons (52%) practiced for more than 20 years and 30% treated more than 50 new patients with breast cancer annually. Attending surgeon explained a large amount (20%) of the variation in CPM, controlling for patient factors. The odds of a patient receiving CPM increased almost 3-fold (odds ratio, 2.8; 95% CI, 2.1-3.4) if she saw a surgeon with a practice approach 1 SD above a surgeon with the mean CPM rate (independent of age, diagnosis date, BRCA status, and risk of second primary). One-quarter (25%) of the surgeon influence was explained by attending attitudes about initial recommendations for surgery and responses to patient requests for CPM. The estimated rate of CPM was 34% for surgeons who least favored initial breast conservation and were least reluctant to perform CPM vs 4% for surgeons who most favored initial breast conservation and were most reluctant to perform CPM.Conclusions and relevanceIn this study, attending surgeons exerted influence on the likelihood of receipt of CPM after a breast cancer diagnosis. Variations in surgeon attitudes about recommendations for surgery and response to patient requests for CPM explain a substantial amount of this influence.

Project description:Importance:Guidelines assert that contralateral prophylactic mastectomy (CPM) should be discouraged in patients without an elevated risk for a second primary breast cancer. However, little is known about the impact of surgeons discouraging CPM on patient care satisfaction or decisions to seek treatment from another clinician. Objective:To examine the association between patient report of first-surgeon recommendation against CPM and the extent of discussion about it with 3 outcomes: patient satisfaction with surgery decisions, receipt of a second opinion, and receipt of surgery by a second surgeon. Design, Setting, and Participants:This population-based survey study was conducted in Georgia and California. We identified 3880 women with stages 0 to II breast cancer treated in 2013-2014 through the Surveillance, Epidemiology, and End Results registries of Georgia and Los Angeles County. Surveys were sent approximately 2 months after surgery (71% response rate, n?=?2578). In this analysis conducted from February to May 2016, we included patients with unilateral breast cancer who considered CPM (n?=?1140). Patients were selected between July 2013 and September 2014. Main Outcomes and Measures:We examined report of surgeon recommendations, level of discussion about CPM, satisfaction with surgical decision making, receipt of second surgical opinion, and surgery from a second surgeon. Results:The mean (SD) age of patients included in this study was 56 (10.6) years. About one-quarter of patients (26.7%; n?=?304) reported that their first surgeon recommended against CPM and 30.1% (n?=?343) reported no substantial discussion about CPM. Dissatisfaction with surgery decision was uncommon (7.6%; n?=?130), controlling for clinical and demographic characteristics. One-fifth of patients (20.6%; n?=?304) had a second opinion about surgical options and 9.8% (n?=?158) had surgery performed by a second surgeon. Dissatisfaction was very low (3.9%; n?=?42) among patients who reported that their surgeon did not recommend against CPM but discussed it. Dissatisfaction was substantively higher for those whose surgeon recommended against CPM with no substantive discussion (14.5%; n?=?37). Women who received a recommendation against CPM were not more likely to seek a second opinion (17.1% among patients with recommendation against CPM vs 15.1% of others; P?=?.52) nor to receive surgery by a second surgeon (7.9% among patients with recommendation against CPM vs 8.3% of others; P?=?.88). Conclusions and Relevance:Most patients are satisfied with surgical decision making. First-surgeon recommendation against CPM does not appear to substantively increase patient dissatisfaction, use of second opinions, or loss of the patient to a second surgeon.

Project description:Importance:Contralateral prophylactic mastectomy (CPM) use is increasing among women with unilateral breast cancer, but little is known about treatment decision making or physician interactions in diverse patient populations. Objective:To evaluate patient motivations, knowledge, and decisions, as well as the impact of surgeon recommendations, in a large, diverse sample of patients who underwent recent treatment for breast cancer. Design, Setting, and Participants:A survey was sent to 3631 women with newly diagnosed, unilateral stage 0, I, or II breast cancer between July 2013 and September 2014. Women were identified through the population-based Surveillance Epidemiology and End Results registries of Los Angeles County and Georgia. Data on surgical decisions, motivations for those decisions, and knowledge were included in the analysis. Logistic and multinomial logistic regression of the data were conducted to identify factors associated with (1) CPM vs all other treatments combined, (2) CPM vs unilateral mastectomy (UM), and (3) CPM vs breast-conserving surgery (BCS). Associations between CPM receipt and surgeon recommendations were also evaluated. All statistical models and summary estimates were weighted to be representative of the target population. Main Outcomes and Measures:Receipt of CPM was the primary dependent variable for analysis and was measured by a woman's self-report of her treatment. Results:Of the 3631 women selected to receive the survey, 2578 (71.0%) responded and 2402 of these respondents who did not have bilateral disease and for whom surgery type was known constituted the final analytic sample. The mean (SD) age was 61.8 (12) years at the time of the survey. Overall, 1301 (43.9%) patients considered CPM (601 [24.8%] considered it very strongly or strongly); only 395 (38.1%) of them knew that CPM does not improve survival for all women with breast cancer. Ultimately, 1466 women (61.6%) received BCS, 508 (21.2%) underwent UM, and 428 (17.3%) received CPM. On multivariable analysis, factors associated with CPM included younger age (per 5-year increase: odds ratio [OR], 0.71; 95% CI, 0.65-0.77), white race (black vs white: OR, 0.50; 95% CI, 0.34-0.74), higher educational level (OR, 1.69; 95% CI, 1.20-2.40), family history (OR, 1.63; 95% CI, 1.22-2.17), and private insurance (Medicaid vs private insurance: OR, 0.47; 95% CI, 0.28-0.79). Among 1569 patients (65.5%) without high genetic risk or an identified mutation, 598 (39.3%) reported a surgeon recommendation against CPM, of whom only 12 (1.9%) underwent CPM, but among the 746 (46.8%) of these women who received no recommendation for or against CPM from a surgeon, 148 (19.0%) underwent CPM. Conclusions and Relevance:Many patients consider CPM, but knowledge about the procedure is low and discussions with surgeons appear to be incomplete. Contralateral prophylactic mastectomy use is substantial among patients without clinical indications but is low when patients report that their surgeon recommended against it. More effective physician-patient communication about CPM is needed to reduce potential overtreatment.
