Project description:BackgroundBreast cancer (BC) patients who are treated with mastectomy are frequently offered immediate breast reconstruction. This study aimed to assess decisional conflict in patients considering immediate breast reconstruction, and to identify factors associated with clinically significant decisional conflict (CSDC).MethodsBaseline data of a multicenter randomized controlled trial evaluating the impact of an online decision aid for BC patients considering immediate breast reconstruction after mastectomy were analyzed. Participants completed questionnaires assessing sociodemographic and clinical characteristics, decisional conflict and other patient-reported outcomes related to decision-making such as breast reconstruction preference, knowledge, information resources used, preferred involvement in decision-making, information coping style, and anxiety. Multivariable logistic regression analysis was performed to identify factors associated with CSDC (score > 37.5 on decisional conflict).ResultsOf the 250 participants, 68% experienced CSDC. Patients with a slight preference for breast reconstruction (odds ratio (OR) = 6.19, p < .01), with no preference for or against breast reconstruction (OR = 11.84, p < .01), and with a strong preference for no breast reconstruction (OR = 5.20, p < .05) were more likely to experience CSDC than patients with a strong preference for breast reconstruction. Furthermore, patients with more anxiety were more likely to experience CSDC (OR = 1.03, p = .01).ConclusionA majority of BC patients who consider immediate breast reconstruction after mastectomy experience clinically significant decisional conflict. The findings emphasize the need for decision support, especially for patients who do not have a strong preference for breast reconstruction.

Project description:BackgroundAn increasing number of patients undergo contralateral prophylactic mastectomy (CPM) for unilateral breast cancer. However, the benefit of CPM has not been quantified in the setting of contemporary breast cancer therapy.MethodsWe performed an analysis of 180 068 patients in the Surveillance, Epidemiology, and End Results (SEER) database, diagnosed with unilateral ductal breast carcinoma between 1998 and 2013 and treated with unilateral mastectomy (UM) or CPM. UM was performed in 146 213 patients (81.2%); CPM was performed in 33 855 patients (19.8%). Primary outcome of interest was cumulative incidence of a second primary breast cancer in the ipsilateral or contralateral breast greater than 3 months after initial diagnosis. Cumulative incidence analysis was based on a Cox proportional model to generate curves of second primary breast cancer in any breast, ipsilateral breast only, or contralateral breast only.ResultsPatients who underwent CPM had a significantly reduced incidence of second primary breast cancer 10 and 15 years after surgery (CPM 0.93% [0.73%, 1.12%] vs UM 4.44% [4.28%, 4.60%]). Patients who underwent CPM had significantly lower adjusted hazard of second primary breast cancer when compared with UM (HR 0.38 vs 1.0, P < .0001).ConclusionsCPM offers some protection from a second primary breast cancer, attributable to a reduced incidence in the contralateral breast. These findings provide additional information to providers and patients as they make decisions regarding surgical management. They should also be interpreted in the context of the absolute incidence of second primary breast cancer after UM and previous literature demonstrating no survival benefit.

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: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.

Project description:BACKGROUND AND OBJECTIVES:Women with unilateral early-stage breast cancer are increasingly choosing contralateral prophylactic mastectomy (CPM) despite the absence of survival benefits and increased risk of surgical complications. Data are lacking on whether this trend extends to women with clinically locally advanced nonmetastatic (cT4M0) cancer. This study aims to estimate national CPM trends in women with unilateral cT4M0 breast cancer. METHODS:Women aged???18 years, who underwent mastectomy during 2004 to 2014 for unilateral cT4M0 breast cancer were identified using the National Cancer Database and grouped as all locally advanced (T4), chest wall invasion, skin nodule/ulceration, or both (T4abc), and inflammatory (T4d) cancer. Poisson regression for trends and logistic modeling for predictors of CPM were performed. RESULTS:Of 23 943 women, 41% had T4abc disease and 35% T4d. Cumulative CPM rates were 15%, 23%, and 18%, for the T4abc, T4d, and all T4 groups, respectively. Trend analysis revealed a significant upsurge in CPM demonstrating 12% annual growth for T4abc tumors, 8% for T4d and 9% for all T4 (all P?<?0.001). CONCLUSIONS:Increasing numbers of women with unilateral cT4M0 breast cancer are undergoing CPM. This rising trend warrants further research to understand stakeholders' preferences in surgical decision-making for women with locally advanced breast cancer.

Project description:BackgroundRates of contralateral prophylactic mastectomy (CPM)-removal of the healthy breast following breast cancer diagnosis-have increased, particularly among women for whom CPM provides no survival benefit. Affective (i.e., emotional) decision making is often blamed for this increase. We studied whether greater negative breast cancer affect could motivate uptake of CPM through increased cancer risk perceptions and biased treatment evaluations.MethodsWe randomly assigned healthy women with average breast-cancer risk (N = 1030; Mage = 44.14, SD = 9.23 y) to 1 of 3 affect conditions (negative v. neutral v. positive narrative manipulation) in a hypothetical online experiment in which they were asked to imagine being diagnosed with cancer in one breast. We assessed 1) treatment choice, 2) affect toward CPM, and 3) perceived risk of future breast cancer in each breast (cancer affected and healthy) following lumpectomy, single mastectomy, and CPM.ResultsThe manipulation caused women in the negative and neutral narrative conditions (26.9% and 26.4%, respectively) to choose CPM more compared with the positive narrative condition (19.1%). Across conditions, women's CPM affect did not differ. However, exploratory analyses addressing a possible association of affect toward cancer-related targets suggested that women in the negative narrative condition may have felt more positively toward CPM than women in the positive narrative condition. The manipulation did not have significant effects on breast cancer risk perceptions.LimitationsThe manipulation of affect had a small effect size, possibly due to the hypothetical nature of this study and/or strong a priori knowledge and attitudes about breast cancer and its treatment options.ConclusionIncreased negative affect toward breast cancer increased choice of CPM over other surgical options and might have motivated more positive affective evaluations of CPM.HighlightsThis study used narratives to elicit different levels of negative integral affect toward breast cancer to investigate the effects of affect on breast cancer treatment choices.Increased negative affect toward breast cancer increased the choice of double mastectomy over lumpectomy and single mastectomy to treat a hypothetical, early-stage cancer.The narrative manipulation of negative affect toward breast cancer did not change the perceived risks of future cancer following any of the surgical interventions.Negative affect toward breast cancer may have biased affective evaluations of double mastectomy.

Project description:The use of contralateral prophylactic mastectomy (CPM) in the U.S. among patients with unilateral invasive breast cancer increased by 150% from 1993 to 2003. Although CPM has been shown to reduce the risk for developing contralateral breast cancer, there is conflicting evidence on whether or not it reduces breast cancer mortality or overall death. The increase in the CPM rate is especially concerning among women with early-stage sporadic breast cancer who have a minimal annual risk for developing contralateral breast cancer, and for many of these women the risk for distant metastatic disease outweighs the risk for contralateral breast cancer. The lack of information about the clinical value of CPM in women with sporadic breast cancer is an important public health problem. This review evaluates current data on the clinical indications for CPM and long-term patient satisfaction and psychosocial outcomes. Gaps in knowledge about the clinical value of CPM, including patient- and physician-related psychosocial factors that influence the decision-making process of CPM among women with sporadic breast cancer, are highlighted.

Project description:Gene expression in histologically normal epithelium from breast cancer patients and cancer-free prophylactic mastectomy patients share a similar profile Introduction: We hypothesized that gene expression in histologically normal epithelium (NlEpi) would differ in breast cancer patients (HN) compared to usual-risk controls undergoing reduction mammoplasty (RM), and that gene expression in NlEpi from cancer-free prophylactic mastectomies from high-risk women (PM), would resemble HN gene expression. Methods: We analyzed gene expression in 73 NlEpi samples microdissected from frozen tissue. In 42 cases, we used Affymetrix HU133A microarrays to compare gene expression in 18 RM vs 18 age-matched HN (9 ER+, 9 ER-) and 6 PM. Data were validated with qPCR in 31 independent NlEpi samples (8 RM, 17 HN, 6 PM). Results: 98 probesets (86 genes) were differentially expressed between RM and HN samples. Perfoming supervised hierarchical analysis with these 98 probesets, PM and HN samples clustered together, away from RM samples. qPCR validation of independent samples was high (84%) and uniform in RM vs HN, and lower (58%), but more heterogeneous, in RM vs PM. The 86 genes were implicated in many processes including transcription and the MAPK pathway. Conclusion: Gene expression differs between NlEpi of cancer cases and controls. The cancer cases' profile can be discerned in high-risk NlEpi. This suggests that the profile is not an effect of the tumor, but may mark increased risk and reveal breast cancer's earliest genomic changes. We determined that 98 probesets significantly differed between reduction mammoplasty and histologically normal epithelium from breast cancer patients. We also found that the histologically normal epithelium from prophylactic mastectomy patients' gene expression was more similar to histologically normal epithelium from breast cancer patients' than to reduction mammoplasty patients' gene expression. These results demonstrate that gene expression differs between NlEpi of cancer cases and controls. The cancer cases’ profile can be discerned in high-risk NlEpi. This suggests that the profile is not an effect of the tumor, but may mark increased risk and reveal breast cancer's earliest genomic changes.

Project description:PurposeDespite lack of survival benefit, demand for contralateral prophylactic mastectomy (CPM) to treat unilateral breast cancer remains high. High uptake of CPM has been demonstrated in Midwestern rural women. Greater travel distance for surgical treatment is associated with CPM. Our objective was to examine the relationship between rurality and travel distance to surgery with CPM.MethodsWomen diagnosed with stages I-III unilateral breast cancer between 2007 and 2017 were identified using the National Cancer Database. Logistic regression was used to model likelihood of CPM based on rurality, proximity to metropolitan centers, and travel distance. A multinomial logistic regression model compared factors associated with CPM with reconstruction versus other surgical options.ResultsBoth rurality (OR 1.10, 95% CI 1.06-1.15 for non-metro/rural vs. metro) and travel distance (OR 1.37, 95% CI 1.33-1.41 for those who traveled 50 + miles vs. < 30 miles) were independently associated with CPM. For women who traveled 30 + miles, odds of receiving CPM were highest for non-metro/rural women (OR 1.33 for 30-49 miles, OR 1.57 for 50 + miles; reference: metro women traveling < 30 miles). Non-metro/rural women who received reconstruction were more likely to undergo CPM regardless of travel distance (ORs 1.11-1.21). Both metro and metro-adjacent women who received reconstruction were more likely to undergo CPM only if they traveled 30 + miles (ORs 1.24-1.30).ConclusionThe impact of travel distance on likelihood of CPM varies by patient rurality and receipt of reconstruction. Further research is needed to understand how patient residence, travel burden, and geographic access to comprehensive cancer care services, including reconstruction, influence patient decisions regarding surgery.

Project description:ImportanceGuidelines 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.ObjectiveTo 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 participantsThis 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 measuresWe 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.ResultsThe 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 relevanceMost 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.
