RESUMO

PURPOSE: Triple-negative breast cancer (TNBC) is an aggressive subtype most prevalent among women of Western Sub-Saharan African ancestry. It accounts for 15-25% of African American (AA) breast cancers (BC) and up to 80% of Ghanaian breast cancers, thus contributing to outcome disparities in BC for black women. The aggressive biology of TNBC has been shown to be regulated partially by breast cancer stem cells (BCSC) which mediate tumor recurrence and metastasis and are more abundant in African breast tumors. METHODS: We studied the biological differences between TNBC in women with African ancestry and those of Caucasian women by comparing the gene expression of the BCSC. From low-passage patient derived xenografts (PDX) from Ghanaian (GH), AA, and Caucasian American (CA) TNBCs, we sorted for and sequenced the stem cell populations and analyzed for differential gene enrichment. RESULTS: In our cohort of TNBC tumors, we observed that the ALDH expressing stem cells display distinct ethnic specific gene expression patterns, with the largest difference existing between the GH and AA ALDH+ cells. Furthermore, the tumors from the women of African ancestry [GH/AA] had ALDH stem cell (SC) enrichment for expression of immune related genes and processes. Among the significantly upregulated genes were CD274 (PD-L1), CXCR9, CXCR10 and IFI27, which could serve as potential drug targets. CONCLUSIONS: Further exploration of the role of immune regulated genes and biological processes in BCSC may offer insight into developing novel approaches to treating TNBC to help ameliorate survival disparities in women with African ancestry.

RESUMO

INTRODUCTION: Triple-negative breast cancer (TNBC) is more common among African American (AA) and western sub-Saharan African breast cancer (BC) patients compared with White/Caucasian Americans (WA) and Europeans. Little is known about TNBC in east Africa. METHODS: Invasive BC diagnosed 1998-2014 were evaluated: WA and AA patients from the Henry Ford Health System in Detroit, Michigan; Ghanaian/west Africans from the Komfo Anokye Teaching Hospital in Kumasi, Ghana; and Ethiopian/east Africans from the St. Paul's Hospital Millennium Medical College in Addis Ababa, Ethiopia. Histopathology and immunohistochemistry for estrogen receptor (ER), progesterone receptor (PR), and HER2/neu expression was performed in Michigan on formalin-fixed, paraffin-embedded samples from all cases. RESULTS: A total of 234 Ghanaian (mean age 49 years), 94 Ethiopian (mean age 43 years), 272 AA (mean age 60 years), and 321 WA (mean age 62 years; p = 0.001) patients were compared. ER-negative and TNBC were more common among Ghanaian and AA compared with WA and Ethiopian cases (frequency ER-negativity 71.1 and 37.1 % vs. 19.8 and 28.6 % respectively, p < 0.0001; frequency TNBC 53.2 and 29.8 % vs. 15.5 and 15.0 %, respectively, p < 0.0001). Among patients younger than 50 years, prevalence of TNBC remained highest among Ghanaians (50.8 %) and AA (34.3 %) compared with WA and Ethiopians (approximately 16 % in each; p = 0.0002). CONCLUSIONS: This study confirms an association between TNBC and West African ancestry; TNBC frequency among AA patients is intermediate between WA and Ghanaian/West Africans consistent with genetic admixture following the west Africa-based trans-Atlantic slave trade. TNBC frequency was low among Ethiopians/East Africans; this may reflect less shared ancestry between AA and Ethiopians.

RESUMO

BACKGROUND: Postmastectomy breast reconstruction is an important component of breast cancer care, but few receive it at the time of the mastectomy. Virtually nothing is known about receipt of reconstruction after initial cancer therapy and why treatment might be delayed. MATERIALS AND METHODS: A 5-year follow-up survey was mailed to a population-based cohort of mastectomy-treated breast cancer patients who were initially surveyed at time of diagnosis in 2002 and reported to the Los Angeles and Detroit SEER registries (N = 645, response rate 60%). Outcomes were receipt of reconstruction (immediate [IR], delayed [DR], or none) and patient appraisal of their treatment decisions. RESULTS: About one-third (35.9%) had IR, 11.5% had DR, and 52.6% had no reconstruction. One-third delayed reconstruction because they focused more on other cancer interventions, and nearly half were concerned about surgical complications and interference with cancer surveillance. Two-thirds of those with no reconstruction said that the procedure was not important to them. A large proportion of all patients were satisfied with their reconstruction decision-making (89.4% IR, 78.4% DR, 80.4% no reconstruction, P = NS). However, only 59.3% of those with no reconstruction felt that they were adequately informed about their reconstructive options (vs 82.7% IR and 78.4% DR, P < .01). CONCLUSIONS: There was modest uptake of breast reconstruction after initial cancer treatment. Factors associated with delayed reconstruction were primarily related to uncertainty about the procedure, concern about cancer surveillance, and low priority. Those without reconstruction demonstrated significant informational needs, which should be addressed with future research efforts.

RESUMO

Funding agencies are increasingly seeking team-based approaches to tackling complex research questions, but there is a need to mobilize translational teams and create shared visions and strategic action plans long before specific funding opportunities are considered or even released. This is particularly evident for teams who want to pursue large-scale grants, where cross-disciplinary synergy is often required. In response, we created Research Jams, which are engaging yet structured brainstorming sessions that bring together groups for the first time to collectively generate novel research ideas, critically map the future of initiatives, prioritize opportunities and next steps, and build community. Research Jams leveraged various aspects of design thinking, including divergence and convergence, visual thinking, and amplifying diversity. We piloted seven Research Jams for a collective 129 researchers, staff, and partners across 50 University of Michigan units and external organizations. Feedback was overwhelmingly positive, with the vast majority of survey respondents indicating that the sessions were helpful for surfacing shared ideas or visions and that opportunities emerged they would like to pursue. Research Jams were ideal for cross-disciplinary groups who wanted to collaboratively ideate and strategize around complex problems in translational research. Importantly, these models have the potential for implementation with groups in any disciplinary domain who want to spur collaborations to address challenging problems. Our ultimate goal is for Research Jams to be the first intervention within a comprehensive support pathway that extends from early brainstorming all the way to grant submission.

RESUMO

PURPOSE: Population-based incidence rates of breast cancers that are negative for estrogen receptor (ER), progesterone receptor, and human epidermal growth factor receptor 2/ neu (triple-negative breast cancer [TNBC]) are higher among African American (AA) compared with white American (WA) women, and TNBC prevalence is elevated among selected populations of African patients. The extent to which TNBC risk is related to East African versus West African ancestry, and whether these associations extend to expression of other biomarkers, is uncertain. METHODS: We used immunohistochemistry to evaluate estrogen receptor, progesterone receptor, human epidermal growth factor receptor 2/ neu, androgen receptor and aldehyde dehydrogenase 1 (ALDH1) expression among WA (n = 153), AA (n = 76), Ethiopian (Eth)/East African (n = 90), and Ghanaian (Gh)/West African (n = 286) patients with breast cancer through an institutional review board-approved international research program. RESULTS: Mean age at diagnosis was 43, 49, 60, and 57 years for the Eth, Gh, AA, and WA patients, respectively. TNBC frequency was higher for AA and Gh patients (41% and 54%, respectively) compared with WA and Eth patients (23% and 15%, respectively; P < .001) Frequency of ALDH1 positivity was higher for AA and Gh patients (32% and 36%, respectively) compared with WA and Eth patients (23% and 17%, respectively; P = .007). Significant differences were observed for distribution of androgen receptor positivity: 71%, 55%, 42%, and 50% for the WA, AA, Gh, and Eth patients, respectively ( P = .008). CONCLUSION: Extent of African ancestry seems to be associated with particular breast cancer phenotypes. West African ancestry correlates with increased risk of TNBC and breast cancers that are positive for ALDH1.

RESUMO

OBJECTIVE: To evaluate factors associated with women's reported level of involvement in breast cancer surgical treatment decision making, and the factors associated with the match between actual and preferred involvement in this decision. METHODS: Survey data from breast cancer patients in Detroit and Los Angeles was merged with surgeon data for an analytic dataset of 1101 patients and 277 surgeons. Decisional involvement and the match between actual and preferred amount of involvement were analyzed as three-level dependent variables using multinomial logistic regression controlling for clustering within surgeons. Independent variables included patient demographic and clinical factors, surgeon demographic and practice factors, cancer program designation, and two measures of patient-surgeon communication. RESULTS: We found variation in women's actual decisional involvement and match between actual and preferred involvement. Women with a surgeon-based or patient-based (versus shared) decision were significantly (p < or = 0.05) younger. Women who had too little decisional involvement (versus the right amount) were younger, while women with too much involvement had less education. Patient-surgeon communication variables were significantly associated with both involvement and match, and higher surgeon volume as associated with too little involvement. CONCLUSION: Patient factors and patient-surgeon communication influence women's perception of their involvement in breast cancer surgical treatment decision making. PRACTICE IMPLICATIONS: Decision tools are needed across surgeons and practice settings to elicit patients' preferences for involvement in treatment decisions for breast cancer.

RESUMO

PURPOSE: Concerns have been raised about the quality of treatment for women with ductal carcinoma-in-situ (DCIS) because persistent high rates of mastectomy suggest overtreatment, whereas lower than expected rates of radiation therapy after breast-conserving surgery (BCS) suggest undertreatment. PATIENTS AND METHODS: All women with DCIS diagnosed in 2002 and who reported to the Detroit and Los Angeles Surveillance, Epidemiology, and End Results (SEER) registries were identified and surveyed shortly after receipt of surgery (response rate, 79.7%; n = 817). Analyses were restricted to patients with DCIS (n = 659) indicated by SEER stage data. RESULTS: Only 14.0% of patients at lowest risk of recurrence (based on tumor size and histologic grade) received a mastectomy compared with 22.8% and 52.6% of patients at intermediate and highest risk (P < .001). Only 13.1% of patients who were not influenced or slightly influenced by concerns about recurrence received mastectomy compared with 48.8% of women who were greatly influenced by this concern (P < .001). A between-geographic site difference in receipt of radiation after BCS was observed for the lowest risk group (38.9% in Los Angeles v 70.5% in Detroit) but not for the highest risk group (80.2% in Los Angeles v 85.9% in Detroit, P = .006 for site and risk group differences). Between-site differences in receipt of radiation after BCS were consistent with patient recall of surgeon discussions about treatment. CONCLUSION: Surgeons are tailoring their recommendations for local therapy options for DCIS based on important clinical factors. Patient attitudes also play an important role in treatment decisions. The substantial influence of both surgeon opinion and patient attitudes should temper concerns about the quality of treatment for women with DCIS.

RESUMO

PURPOSE: High rates of mastectomy and marked regional variations have motivated lingering concerns about overtreatment and failure to involve women in treatment decisions. We examined the relationship between patient involvement in decision making and type of surgical treatment for women with breast cancer. METHODS: All women with ductal carcinoma-in-situ and a 20% random sample of women with invasive breast cancer aged 79 years and younger who were diagnosed in 2002 and reported to the Detroit and Los Angeles Surveillance, Epidemiology, and End Results registries were identified and surveyed shortly after receipt of surgical treatment (response rate, 77.4%; n = 1,844). RESULTS: Mean age was 60.1 years; 70.2% of the women were white, 18.0% were African American, and 11.8% were from other ethnic groups. Overall, 30.2% of women received mastectomy as initial treatment. Most women reported that they made the surgical decision (41.0%) or that the decision was shared (37.1%); 21.9% of patients reported that their surgeon made the decision with or without their input. Among white women, only 5.3% of patients whose surgeon made the decision received mastectomy compared with 16.8% of women who shared the decision and 27.0% of women who made the decision (P < .001, adjusted for clinical factors, predisposing factors, and number of surgeons visited). However, this association was not observed for African American women (Wald test 10.0, P = .041). CONCLUSION: Most women reported that they made or shared the decision about surgical treatment. More patient involvement in decision making was associated with greater use of mastectomy. Racial differences in the association of involvement with receipt of treatment suggest that the decision-making process varies by racial groups.

RESUMO

OBJECTIVES: Previous research has generally found that racial/ethnic differences in breast cancer stage at diagnosis attenuate when measures of socioeconomic status are included in the analysis, although most previous research measured socioeconomic status at the contextual level. This study investigated the relation between race/ethnicity, individual socioeconomic status, and breast cancer stage at diagnosis. METHODS: Women with stage 0 to III breast cancer were identified from population-based data from the Surveillance, Epidemiology, and End Results tumor registries in the Detroit and Los Angeles metropolitan areas. These data were combined with data from a mailed survey in a sample of White, Black, and Hispanic women (n=1700). Logistic regression identified factors associated with early-stage diagnosis. RESULTS: Black and Hispanic women were less likely to be diagnosed with early-stage breast cancer than were White women (P< .001). After control for study site, age, and individual socioeconomic factors, the odds of early detection were still significantly less for Hispanic women (odds ratio [OR]=0.45) and Black women (OR = 0.72) than for White women. After control for the method of disease detection, the White/Black disparity attenuated to insignificance; the decreased likelihood of early detection among Hispanic women remained significant (OR=0.59). CONCLUSION: The way in which racial/ethnic minority status and socioeconomic characteristics produce disparities in women's experiences with breast cancer deserves further research and policy attention.

RESUMO

OBJECTIVE: Although involving women in breast cancer treatment decisions is advocated, there is little understanding of whether women have the information they need to make informed decisions. The objective of the current study was to evaluate women's knowledge of survival and recurrence rates for mastectomy and breast conserving surgery (BCS) and the factors associated with this knowledge. METHODS: We used a population-based sample of women diagnosed with breast cancer in metropolitan Los Angeles and Detroit between December 2001 and January 2003. All women with ductal carcinoma in situ and a random sample of women with invasive disease were selected (N=2382), of which 1844 participated (77.4%). All participants were mailed surveys. The main outcome measures were knowledge of survival and recurrence rates by surgical treatment type. RESULTS: Only 16% of women knew that recurrence rates were different for mastectomy and BCS, and 48% knew that the survival rates were equivalent across treatment. Knowledge about survival and recurrence was improved by exposure to the Internet and health pamphlets (p<0.01). Women who had a female (versus male) surgeon, and/or a surgeon who explained both treatments (rather than just one treatment) demonstrated higher survival knowledge (p<0.01). The majority of women had inadequate knowledge with which to make informed decisions about breast cancer surgical treatment. CONCLUSION: Previous explanations for poor knowledge, such as irrelevance of knowledge to decision making and lack of access to information, were not shown to be plausible explanations for the low levels of knowledge observed in this sample. PRACTICE IMPLICATIONS: These results suggest a need for fundamental changes in patient education to ensure that women are able to make informed decisions about their breast cancer treatment. These changes may include an increase in the use of decision aids and in decreasing the speed at which treatment decisions are made.

RESUMO

Women with African ancestry in western, sub-Saharan Africa and in the United States represent a population subset facing an increased risk of being diagnosed with biologically aggressive phenotypes of breast cancer that are negative for the estrogen receptor, the progesterone receptor, and the HER2/neu marker. These tumors are commonly referred to as triple-negative breast cancer. Disparities in breast cancer incidence and outcome related to racial or ethnic identity motivated the establishment of the International Breast Registry, on the basis of partnerships between the Komfo Anokye Teaching Hospital in Kumasi, Ghana, the University of Michigan Comprehensive Cancer Center in Ann Arbor, Michigan, and the Henry Ford Health System in Detroit, Michigan. This research collaborative has featured educational training programs as well as scientific investigations related to the comparative biology of breast cancer in Ghanaian African, African American, and white/European American patients. Currently, the International Breast Registry has expanded to include African American patients throughout the United States by partnering with the Sisters Network (a national African American breast cancer survivors' organization) and additional sites in Ghana (representing West Africa) as well as Ethiopia (representing East Africa). Its activities are now coordinated through the Henry Ford Health System International Center for the Study of Breast Cancer Subtypes. Herein, we review the history and results of this international program at its 10-year anniversary.

RESUMO

OBJECTIVE: To better understand medical decision making in the context of "preference sensitive care," we investigated factors associated with breast cancer patients' satisfaction with the type of surgery received and with the decision process. DATA SOURCES/DATA COLLECTION: For a population-based sample of recently diagnosed breast cancer patients in the Detroit and Los Angeles metropolitan areas (N=1,633), demographic and clinical data were obtained from the Surveillance, Epidemiology, and End Results tumor registry, and self-reported psychosocial and satisfaction data were obtained through a mailed survey (78.4 percent response rate). STUDY DESIGN: Cross-sectional design in which multivariable logistic regression was used to identify sociodemographic and clinical factors associated with three satisfaction measures: low satisfaction with surgery type, low satisfaction with the decision process, and decision regret. PRINCIPAL FINDINGS: Overall, there were high levels of satisfaction with both surgery and the decision process, and low rates of decision regret. Ethnic minority women and those with low incomes were more likely to have low satisfaction or decision regret. In addition, the match between patient preferences regarding decision involvement and their actual level of involvement was a strong indicator of satisfaction and decision regret/ambivalence. While having less involvement than preferred was a significant indicator of low satisfaction and regret, having more involvement than preferred was also a risk factor. Women who received mastectomy without reconstruction were more likely to report low satisfaction with surgery (odds ratio [OR]=1.54, p<.05), low satisfaction with the process (OR=1.37, p<.05), and decision regret (OR=1.55, p<.05) compared with those receiving breast conserving surgery (BCS). An additional finding was that as patients' level of involvement in the decision process increased, the rate of mastectomy also increased (p<.001). CONCLUSIONS: A significant proportion of breast cancer patients experience a decision process that matches their preferences for participation, and report satisfaction with both the process and the outcome. However, women who report more involvement in the decision process are significantly less likely to receive a lumpectomy. Thus, increasing patient involvement in the decision process will not necessarily increase use of BCS or lead to greater satisfaction. The most salient aspect for satisfaction with the decision making process is the match between patients' preferences and experiences regarding participation.

RESUMO

PURPOSE: Disparities in receipt of adjuvant chemotherapy may contribute to higher breast cancer fatality rates among black and Hispanic women compared with non-Hispanic whites. We investigated factors associated with receipt of chemotherapy in a diverse population-based sample. PATIENTS AND METHODS: Women diagnosed with breast cancer between August 2005 and May 2007 (N = 3,252) and reported to the Detroit, Michigan, or Los Angeles County Surveillance, Epidemiology, and End Results (SEER) registry were recruited to complete a survey. Multivariable analyses examined factors associated with chemotherapy receipt. RESULTS: The survey was sent to 3,133 patients; 2,290 completed a survey (73.1%), and 1,403 of these patients were included in the analytic sample. In multivariable models, disease characteristics were significantly associated with the likelihood of receiving chemotherapy. Low-acculturated Hispanics were more likely to receive chemotherapy than non-Hispanic whites (odds ratio [OR], 2.00; 95% CI, 1.31 to 3.04), as were high-acculturated Hispanics (OR, 1.43; 95% CI, 1.03 to 1.98). Black women were less likely to receive chemotherapy than non-Hispanic whites, but the difference was not significant (OR, 0.83; 95% CI, 0.64 to 1.08). Increasing age (even in women age < 50 years) and Medicaid insurance were associated with lower rates of chemotherapy receipt. CONCLUSION: In this population-based sample, disease characteristics were strongly associated with receipt of chemotherapy, indicating that clinical benefit guides most treatment decisions. We found no compelling evidence that black women and Hispanics receive chemotherapy at lower rates. Interventions that address chemotherapy use rates according to age and insurance status may improve quality of systemic treatment.

RESUMO

BACKGROUND: Plastic surgery demographics are transforming, with a greater proportion of women and younger physicians who desire balance between their career and personal lives compared with previous generations. The authors' purpose was to describe the patterns and correlates of satisfaction with work-life balance among U.S. plastic surgeons. METHODS: A self-administered survey was mailed to a random sample of American Society of Plastic Surgeons members (n = 708; 71 percent response rate). The primary outcome was satisfaction with work-life balance. Independent variables consisted of surgeon sociodemographic and professional characteristics. Logistic regression was used to evaluate correlates of satisfaction with work-life balance. RESULTS: Overall, over three-fourths of respondents were satisfied with their career; however, only half were satisfied with their time management between career and personal responsibilities. Factors independently associated with diminished satisfaction with work-life balance were being female (odds ratio = 0.63; 95 percent CI, 0.42 to 0.95), working more than 60 hours per week (versus < 60 hours per week; odds ratio = 0.44; 95 percent CI, 0.28 to 0.72), having emergency room call responsibilities (versus no emergency room call, odds ratio = 0.42; 95 percent CI, 0.27 to 0.67), and having a primarily reconstructive practice (versus primarily aesthetic practice; odds ratio = 0.53; 95 percent CI, 0.30 to 0.93). CONCLUSIONS: While generational differences were minimal, surgeons who were female, worked longer hours, and had emergency room call responsibilities and primarily reconstructive practices were significantly less satisfied with their work-life balance.

RESUMO

BACKGROUND: : Concern exists that plastic surgeons have lost interest in postmastectomy breast reconstruction, which has helped enable the oncoplastic movement by general surgery. The authors evaluated patterns and correlates of postmastectomy breast reconstruction among U.S. plastic surgeons. METHODS: A survey was mailed to a national sample of 500 randomly selected members of the American Society of Plastic Surgeons (73 percent of eligible subjects responded; n = 312). The dependent variable was surgeon's annual volume of breast reconstructions (dichotomized into >50 and ≤ 50 cases per year). Logistic regression was used to evaluate factors associated with annual volume, including surgeon demographic and practice characteristics, community support for reconstruction, and surgeons' attitudes toward insurance reimbursement. RESULTS: Ninety percent found doing breast reconstruction personally rewarding, and nearly all enjoyed the technical aspects of the procedure. The majority of surgeons, however, were low-volume to moderate-volume providers, and 43 percent reported decreasing their volume over the past year due to poor reimbursement. Resident availability was significantly associated with high volume (odds ratio, 4.93; 95 percent CI, 2.31 to 10.49); years in practice and perceived financial constraints by third-party payers were inversely associated with high volume (>20 years compared with ≤ 10 years: odds ratio, 0.23. 95 percent CI, 0.07 to 0.71; odds ratio, 0.22, 95 percent CI, 0.08 to 0.56, respectively). CONCLUSIONS: Although plastic surgeons find breast reconstruction professionally rewarding, many are decreasing their practice. Factors associated with low volume include lack of resident coverage and perceived poor reimbursement. Advocacy efforts must be directed at facilitating reconstructive services for this highly demanding patient population.

RESUMO

SUMMARY: Survey research is a unique methodology that can provide insight into individuals' perspectives and experiences and can be collected on a large population-based sample. Specifically, in plastic surgery, survey research can provide patients and providers with accurate and reproducible information to assist with medical decision-making. When using survey methods in research, researchers should develop a conceptual model that explains the relationships of the independent and dependent variables. The items of the survey are of primary importance. Collected data are only useful if they accurately measure the concepts of interest. In addition, administration of the survey must follow basic principles to ensure an adequate response rate and representation of the intended target sample. In this article, the authors review some general concepts important for successful survey research and discuss the many advantages this methodology has for obtaining limitless amounts of valuable information.

RESUMO

BACKGROUND: The authors' purpose was to describe patterns and correlates of satisfaction with career choice among U.S. plastic surgeons. METHODS: A mailed, self-administered survey was sent to 708 U.S. plastic surgeons who were randomly sampled from the American Society of Plastic Surgeons registry (71 percent response rate, n = 505). The dependent variable was satisfaction with the decision to become a plastic surgeon, which was created from a scale of four validated questions measuring decisional satisfaction and decisional regret. The independent variables included surgeon and practice characteristics. Logistic regression was used to evaluate associations between satisfaction with the decision to become a plastic surgeon and independent factors. RESULTS: Few respondents (4 percent) regretted becoming plastic surgeons. Factors independently associated with greater satisfaction with the decision to become a plastic surgeon included group practice compared with solo practice (odds ratio, 1.65; 95 percent confidence interval, 1.0 to 2.71), resident educator (odds ratio, 1.88; 95 percent confidence interval, 1.06 to 3.31), and a highly cosmetic practice mix: primarily cosmetic versus primarily reconstructive (odds ratio, 2.42; 95 percent confidence interval, 1.25 to 4.66) and mixed versus primarily reconstructive (odds ratio, 1.59, 95 percent confidence interval, 0.92 to 2.76). Demographic factors such as age and gender were not associated with surgeon satisfaction. CONCLUSIONS: Overall, the majority of plastic surgeons are satisfied with their career choice despite the current health care and economic environment. Factors significantly associated with greater satisfaction with career choice included group practice, involvement in resident education, and a highly elective cosmetic practice.

RESUMO

BACKGROUND: Few studies have evaluated the association between patient decision involvement and surgery received among racially and ethnically diverse patients or patients' attitudes about surgery and the role of family and friends in surgical treatment choices. METHODS: Women diagnosed with nonmetastatic breast cancer from June 2005 through February 2007 and reported to the Los Angeles or Detroit Surveillance, Epidemiology, and End Results registries were mailed a survey after diagnosis (N = 3133). Latina and African American women were oversampled. The response rate was 72.4%. The analytic sample (N = 1651) excluded those with stage IIIA or higher disease, self-reported clinical contraindications to breast-conserving surgery with radiation, and unclear race or ethnicity. The dependent variable was receipt of mastectomy initially. The primary independent variables were patient involvement in decision making, race or ethnicity, attitudes about recurrence, the effects of radiation, the impact of surgery on body image, and the role of others in decision making. Latinas were categorized as low or high acculturated. The association between patient involvement in decision making and the receipt of mastectomy was evaluated using logistic regression while controlling for other independent variables. All statistical tests were two-sided. RESULTS: The analytic sample was 23.9% Latina (12.0% low acculturated, 11.9% high acculturated), 27.1% African American, and 48.9% white, and 17.2% received a mastectomy initially. For each racial or ethnic group, more women who reported a patient-based decision received mastectomy than those who reported a shared or surgeon-based decision (P = .022 for low-acculturated Latinas, P < .001 for other groups). Women who reported that concerns about recurrence or radiation effects were very important in their surgery decision were more likely to receive mastectomy than those less concerned (for recurrence concerns, estimated relative risk [RR] = 1.66, 95% confidence interval [CI] = 1.28 to 2.10; for radiation concerns, estimated RR = 2.35, 95% CI = 1.88 to 2.85). Women who reported that body image concerns and their spouse's opinion were very important in their surgery decision less often received mastectomy than those less concerned about body image or who placed less weight on their spouse's opinion (for body image concerns, estimated RR = 0.47, 95% CI = 0.30 to 0.74; for spouse's opinion, estimated RR = 0.53, 95% CI = 0.36 to 0.78). CONCLUSION: Greater patient involvement in decision making was associated with receipt of mastectomy for all racial and ethnic groups. Patient attitudes about surgery and the opinions of family and friends contribute to surgical choices made by women with breast cancer.

RESUMO

PURPOSE: Latinas and African-Americans with breast cancer, especially those of lower socioeconomic status and acculturation, have been underrepresented in studies assessing treatment satisfaction, decision-making, and quality of life. A study was designed to recruit a large and representative sample of these subgroups. MATERIALS AND METHODS: Incident cases were selected by rapid case ascertainment (RCA) in the Los Angeles Surveillance, Epidemiology, and End Results Registry from 2005 to 2006, with oversampling of Latinas and African-Americans. Patients were mailed a questionnaire and $10 incentive 5 to 6 months after diagnosis; nonrespondents were contacted by telephone. Multivariate analysis was used to assess possible response bias. The RCA definition of Hispanic origin was validated by self-reports. The Short Acculturation Scale for Hispanics index for Latina respondents was used. RESULTS: One thousand six hundred and ninety-eight eligible breast cancer cases were selected and 1,223 participated, for a response rate of 72.0%, which varied little by race/ethnicity. Age, race/ethnicity, and clinical factors were not associated with response; however, respondents were slightly more likely to be married and from higher socioeconomic status census tracts than nonrespondents. The RCA definition of Hispanic identity was highly sensitive (94.6%) and specific (90.0%). Lower acculturation was associated with lower education and literacy among Latinas. DISCUSSION: High response rates among all subgroups were achieved due to the use of RCA, an incentive, extensive telephone follow-up, a native Spanish-speaking interviewer, and a focused questionnaire. The low acculturation index category identified a highly vulnerable subgroup. This large sample representing subgroups with greater problems will provide a basis for developing better interventions to assist these women.
