RESUMO

BACKGROUND: Pancreatic adenocarcinoma (PC) is a highly lethal malignancy with a survival rate of only 12%. Surveillance is recommended for high-risk individuals (HRIs), but it is not widely adopted. To address this unmet clinical need and drive early diagnosis research, we established the Pancreatic Cancer Early Detection (PRECEDE) Consortium. METHODS: PRECEDE is a multi-institutional international collaboration that has undertaken an observational prospective cohort study. Individuals (aged 18-90 years) are enrolled into 1 of 7 cohorts based on family history and pathogenic germline variant (PGV) status. From April 1, 2020, to November 21, 2022, a total of 3,402 participants were enrolled in 1 of 7 study cohorts, with 1,759 (51.7%) meeting criteria for the highest-risk cohort (Cohort 1). Cohort 1 HRIs underwent germline testing and pancreas imaging by MRI/MR-cholangiopancreatography or endoscopic ultrasound. RESULTS: A total of 1,400 participants in Cohort 1 (79.6%) had completed baseline imaging and were subclassified into 3 groups based on familial PC (FPC; n=670), a PGV and FPC (PGV+/FPC+; n=115), and a PGV with a pedigree that does not meet FPC criteria (PGV+/FPC-; n=615). One HRI was diagnosed with stage IIB PC on study entry, and 35.1% of HRIs harbored pancreatic cysts. Increasing age (odds ratio, 1.05; P<.001) and FPC group assignment (odds ratio, 1.57; P<.001; relative to PGV+/FPC-) were independent predictors of harboring a pancreatic cyst. CONCLUSIONS: PRECEDE provides infrastructure support to increase access to clinical surveillance for HRIs worldwide, while aiming to drive early PC detection advancements through longitudinal standardized clinical data, imaging, and biospecimen captures. Increased cyst prevalence in HRIs with FPC suggests that FPC may infer distinct biological processes. To enable the development of PC surveillance approaches better tailored to risk category, we recommend adoption of subclassification of HRIs into FPC, PGV+/FPC+, and PGV+/FPC- risk groups by surveillance protocols.

RESUMO

PURPOSE: To evaluate preferences for and experiences with genetic testing in a diverse cohort of patients with breast cancer identified through population-based registries, with attention to differences by race/ethnicity. METHODS: We surveyed women diagnosed with nonmetastatic breast cancer from 2005 to 2007, as reported to the SEER registries of metropolitan Los Angeles and Detroit, about experiences with hereditary risk evaluation. Multivariable models evaluated correlates of a strong desire for genetic testing, unmet need for discussion with a health care professional, and receipt of testing. RESULTS: Among 1,536 patients who completed the survey, 35% expressed strong desire for genetic testing, 28% reported discussing testing with a health care professional, and 19% reported test receipt. Strong desire for testing was more common in younger women, Latinas, and those with family history. Minority patients were significantly more likely to have unmet need for discussion (failure to discuss genetic testing with a health professional when they had a strong desire for testing): odds ratios of 1.68, 2.44, and 7.39 for blacks, English-speaking Latinas, and Spanish-speaking Latinas compared with whites, respectively. Worry in the long-term survivorship period was higher among those with unmet need for discussion (48.7% v 24.9%; P <.001). Patients who received genetic testing were younger, less likely to be black, and more likely to have a family cancer history. CONCLUSION: Many patients, especially minorities, express a strong desire for genetic testing and may benefit from discussion to clarify risks. Clinicians should discuss genetic risk even with patients they perceive to be at low risk, as this may reduce worry.

RESUMO

BACKGROUND: While studies suggest most women have little regret regarding their breast cancer treatment decisions immediately following treatment, no studies to date have evaluated how regret may change over time. OBJECTIVE: To measure the stability of posttreatment decision regret over time among women with breast cancer. METHODS: Women diagnosed with breast cancer between August 2005 and May 2007 reported to the Detroit, Michigan, or Los Angeles County Surveillance, Epidemiology, and End Results (SEER) registry and completed surveys at 9 months following diagnosis (time 1) and again approximately 4 years later (time 2). A decision regret scale consisting of 5 items was summed to create 2 decision regret scores at both time 1 and time 2 (range, 0-20). Multivariable linear regression was used to examine change in regret from 9 months to 4 years. Independent variables included surgery type, receipt of reconstruction, and recurrence status at follow-up. The model controlled for demographic and clinical factors. RESULTS: The analytic sample included 1536 women. Mean regret in the overall sample was 4.9 at time 1 and 5.4 at time 2 (P < 0.001). In the multivariable linear model, we found no difference in change in decision regret over time by surgery type. Reporting a new diagnosis of breast cancer at time 2 was associated with a 2.6-point increase in regret over time compared with women without an additional diagnosis (P = 0.003). Receipt of reconstruction was not associated with change in decision regret over time. CONCLUSIONS: Decision regret following treatment was low and relatively stable over time for most women. Those facing an additional diagnosis of breast cancer following treatment may be at risk for elevated regret-related distress.

RESUMO

IMPORTANCE: Most women undergoing mastectomy for breast cancer do not undergo breast reconstruction. OBJECTIVE: To examine correlates of breast reconstruction after mastectomy and to determine if a significant unmet need for reconstruction exists. DESIGN, SETTING, AND PARTICIPANTS: We used Surveillance, Epidemiology, and End Results registries from Los Angeles, California, and Detroit, Michigan, for rapid case ascertainment to identify a sample of women aged 20 to 79 years diagnosed as having ductal carcinoma in situ or stages I to III invasive breast cancer. Black and Latina women were oversampled to ensure adequate representation of racial/ethnic minorities. Eligible participants were able to complete a survey in English or Spanish. Of 3252 women sent the initial survey a median of 9 months after diagnosis, 2290 completed it. Those who remained disease free were surveyed 4 years later to determine the frequency of immediate and delayed reconstruction and patient attitudes toward the procedure; 1536 completed the follow-up survey. The 485 who remained disease free at follow-up underwent analysis. EXPOSURES: Disease-free survival of breast cancer. MAIN OUTCOMES AND MEASURES: Breast reconstruction at any time after mastectomy and patient satisfaction with different aspects of the reconstruction decision-making process. RESULTS: Response rates in the initial and follow-up surveys were 73.1% and 67.7%, respectively (overall, 49.4%). Of 485 patients reporting mastectomy at the initial survey and remaining disease free, 24.8% underwent immediate and 16.8% underwent delayed reconstruction (total, 41.6%). Factors significantly associated with not undergoing reconstruction were black race (adjusted odds ratio [AOR], 2.16 [95% CI, 1.11-4.20]; P = .004), lower educational level (AOR, 4.49 [95% CI, 2.31-8.72]; P < .001), increased age (AOR in 10-year increments, 2.53 [95% CI, 1.77-3.61]; P < .001), major comorbidity (AOR, 2.27 [95% CI, 1.01-5.11]; P = .048), and chemotherapy (AOR, 1.82 [95% CI, 0.99-3.31]; P = .05). Only 13.3% of women were dissatisfied with the reconstruction decision-making process, but dissatisfaction was higher among nonwhite patients in the sample (AOR, 2.87 [95% CI, 1.27-6.51]; P = .03). The most common patient-reported reasons for not having reconstruction were the desire to avoid additional surgery (48.5%) and the belief that it was not important (33.8%), but 36.3% expressed fear of implants. Reasons for avoiding reconstruction and systems barriers to care varied by race; barriers were more common among nonwhite participants. Residual demand for reconstruction at 4 years was low, with only 30 of 263 who did not undergo reconstruction still considering the procedure. CONCLUSIONS AND RELEVANCE: Reconstruction rates largely reflect patient demand; most patients are satisfied with the decision-making process about reconstruction. Specific approaches are needed to address lingering patient-level and system factors with a negative effect on reconstruction among minority women.

RESUMO

IMPORTANCE: The growing rate of contralateral prophylactic mastectomy (CPM) among women diagnosed as having breast cancer has raised concerns about potential for overtreatment. Yet, there are few large survey studies of factors that affect women's decisions for this surgical treatment option. OBJECTIVE: To determine factors associated with the use of CPM in a population-based sample of patients with breast cancer. DESIGN, SETTING, AND PARTICIPANTS: A longitudinal survey of 2290 women newly diagnosed as having breast cancer who reported to the Detroit and Los Angeles Surveillance, Epidemiology, and End Results registries from June 1, 2005, to February 1, 2007, and again 4 years later (June 2009 to February 2010) merged with Surveillance, Epidemiology, and End Results registry data (n = 1536). Multinomial logistic regression was used to evaluate factors associated with type of surgery. Primary independent variables included clinical indications for CPM (genetic mutation and/or strong family history), diagnostic magnetic resonance imaging, and patient extent of worry about recurrence at the time of treatment decision making. MAIN OUTCOMES AND MEASURES: Type of surgery received from patient self-report, categorized as CPM, unilateral mastectomy, or breast conservation surgery. RESULTS: Of the 1447 women in the analytic sample, 18.9% strongly considered CPM and 7.6% received it. Of those who strongly considered CPM, 32.2% received CPM, while 45.8% received unilateral mastectomy and 22.8% received breast conservation surgery (BCS). The majority of patients (68.9%) who received CPM had no major genetic or familial risk factors for contralateral disease. Multivariate regression showed that receipt of CPM (vs either unilateral mastectomy or breast conservation surgery) was significantly associated with genetic testing (positive or negative) (vs UM, relative risk ratio [RRR]: 10.48; 95% CI, 3.61-3.48 and vs BCS, RRR: 19.10; 95% CI, 5.67-56.41; P < .001), a strong family history of breast or ovarian cancer (vs UM, RRR: 5.19; 95% CI, 2.34-11.56 and vs BCS, RRR: 4.24; 95% CI, 1.80-9.88; P = .001), receipt of magnetic resonance imaging (vs UM RRR: 2.07; 95% CI, 1.21-3.52 and vs BCS, RRR: 2.14; 95% CI, 1.28-3.58; P = .001), higher education (vs UM, RRR: 5.04; 95% CI, 2.37-10.71 and vs BCS, RRR: 4.38; 95% CI, 2.07-9.29; P < .001), and greater worry about recurrence (vs UM, RRR: 2.81; 95% CI, 1.14-6.88 and vs BCS, RRR: 4.24; 95% CI, 1.80-9.98; P = .001). CONCLUSIONS AND RELEVANCE: Many women considered CPM and a substantial number received it, although few had a clinically significant risk of contralateral breast cancer. Receipt of magnetic resonance imaging at diagnosis contributed to receipt of CPM. Worry about recurrence appeared to drive decisions for CPM although the procedure has not been shown to reduce recurrence risk. More research is needed about the underlying factors driving the use of CPM.

RESUMO

BACKGROUND: Many women with early-stage breast cancer are working at the time of diagnosis and survive without disease recurrence. The short-term impact of chemotherapy receipt on employment has been demonstrated, but the long-term impact merits further research. METHODS: The authors conducted a longitudinal multicenter cohort study of women diagnosed with nonmetastatic breast cancer between 2005 and 2007, as reported to the population-based Los Angeles and Detroit Surveillance, Epidemiology, and End Results program registries. Of 3133 individuals who were sent surveys, 2290 (73%) completed a baseline survey soon after diagnosis and of these, 1536 (67%) completed a 4-year follow-up questionnaire. RESULTS: Of the 1026 patients aged < 65 years at the time of diagnosis whose breast cancer did not recur and who responded to both surveys, 746 (76%) worked for pay before diagnosis. Of these, 236 (30%) were no longer working at the time of the follow-up survey. Women who received chemotherapy as part of their initial treatment were less likely to be working at the time of the follow-up survey (38% vs 27%; P = .003). Chemotherapy receipt at the time of diagnosis (odds ratio, 1.4; P = .04) was found to be independently associated with unemployment during survivorship in a multivariable model. Many women who were not employed during the survivorship period wanted to work: 50% reported that it was important for them to work and 31% were actively seeking work. CONCLUSIONS: Unemployment among survivors of breast cancer 4 years after diagnosis is often undesired and appears to be related to the receipt of chemotherapy during initial treatment. These findings should be considered when patients decide whether to receive adjuvant chemotherapy, particularly when the expected benefit is low.

RESUMO

To describe which providers provide breast cancer survivorship care, we conducted a longitudinal survey of nonmetastatic breast cancer patients identified by the SEER registries of Los Angeles and Detroit. Multinomial logistic regression examined the adjusted odds of surgeon compared with a medical oncologist follow-up or primary care provider compared with medical oncologist follow-up, adjusting for age, race/ethnicity, insurance, tumor stage, receipt of chemotherapy, endocrine therapy use, and visit to a medical oncologist at the time of diagnosis. Results were weighted to account for sample selection and nonresponse. 844 women had invasive disease and received chemotherapy or endocrine therapy. 65.2 % reported medical oncologists as their main care provider at 4 years, followed by PCP/other physicians (24.3 %) and surgeons (10.5 %). Black women were more likely to receive their follow-up care from surgeons (OR 2.47, 95 % CI 1.16-5.27) or PCP/other physicians (OR 2.62, 95 % CI 1.47-4.65) than medical oncologists. Latinas were more likely to report PCP/other physician follow-up than medical oncologists (OR 2.33, 95 % CI 1.15-4.73). Compared with privately insured women, Medicaid recipients were more likely to report PCP/other physician follow-up (OR 2.52, 95 % CI 1.24-5.15). Women taking endocrine therapy 4 years after diagnosis were less likely to report surgeons or PCP/other physicians as their primary provider of breast cancer follow-up care. Different survivorship care patterns emerge on race/ethnicity and insurance status. Interventions are needed to inform patients and providers on the recommended sources of breast cancer follow-up.

RESUMO

PURPOSE/OBJECTIVES: To characterize the perspectives of partners (husbands or significant others) of patients with breast cancer in the treatment decision-making process and to evaluate racial and ethnic differences in decision outcomes. DESIGN: A cross-sectional survey. SETTING: Los Angeles, CA, and Detroit, MI. SAMPLE: 517 partners of a population-based sample of patients with breast cancer four years post-treatment. METHODS: A self-administered mailed questionnaire. Chi-square tests and logistic regression were used to assess associations between race and ethnicity and decision outcomes. MAIN RESEARCH VARIABLES: Decision regret and three elements of the decision process: information received, actual involvement, and desired involvement. FINDINGS: Most partners reported receiving sufficient information (77%), being involved in treatment decisions (74%), and having sufficient involvement (73%). Less-acculturated Hispanic partners were more likely than their Caucasian counterparts to report high decision regret (45% versus 14%, p<0.001). Factors significantly associated (p<0.05) with high decision regret were insufficient receipt of treatment information, low involvement in decision making, and a desire for more involvement. CONCLUSIONS: Partners were generally positive regarding their perspectives about participating in the breast cancer treatment decision-making process. However, less acculturated Hispanic partners were most vulnerable to decision regret. In addition, high decision regret was associated with modifiable elements of the decision-making process. IMPLICATIONS FOR NURSING: Attention should be paid to ensuring racial and ethnic minority partners are sufficiently involved in breast cancer treatment decisions and receive decision support.

RESUMO

OBJECTIVE: The study aimed to characterize cancer-related concerns among women with a new diagnosis of gynecological cancer from a developmental life stage perspective. The study compared the degree of cancer-related concern between young women (45 years or younger), middle age women (46-64 years), and older women (65 years or older). MATERIALS/METHODS: Data from women (N = 243) with a condition diagnosed as primary gynecological cancer who were participating in a randomized control trial were analyzed. Women completed a measure that assessed the degree of concern in 12 cancer-related domains (physical functioning, cancer treatment, emotional functioning, sexual functioning, disease progression/death, own well-being, partner well-being, relationship with spouse/partner, body image, relationship with others, employment, and finances). Multivariate comparisons were made between the 3 age groups on the cancer-related concerns. RESULTS: There were age group differences in overall cancer-related concern and specific cancer-related domains. Young women reported the greatest cancer-related concern (P < 0.001). They reported greater concern over emotional functioning (P < 0.001) and sexual functioning (P < 0.001) compared to the middle- and older-age groups. Older women reported less concern over the impact of cancer on finances (P = 007). There were no differences between age groups in concern over physical impairment, cancer treatment, disease progression/death, own well-being, partner well-being, relationship with spouse/partner, body image, and relationship with others. CONCLUSIONS: Age may play an important role in the impact of a gynecological cancer diagnosis in domains of functioning, specifically emotional functioning, sexual functioning, and finances. Other cancer-related areas may represent more universal degree of impact. Professionals may benefit from considering the impact of cancer from a developmental life stage perspective.

RESUMO

PURPOSE: This study investigated factors associated with declines in emotional well-being (EWB) over time in breast cancer survivors. METHODS: Women with breast cancer (Stages I-III) residing in Los Angeles, CA, or Detroit, MI, and reported to the Surveillance, Epidemiology, and End Results registries between June 2005 and February 2007 completed surveys at 9 months and 4 years after diagnosis. EWB was measured by the Functional Assessment of Cancer Treatment-Breast. Using a stress coping framework, logistic regression models assessed associations between personal, social, and clinical correlates, appraisal (e.g., worry about recurrence) and coping factors (e.g., emotional support) to EWB declines. RESULTS: Among eligible women who completed primary breast cancer treatment, 772 completed both surveys, and 192 (24.9 %) experienced EWB declines over time. Women with past or current depression were more likely to report EWB decline (p < 0.01). Survivors who perceived they did not receive enough information about risk of breast cancer recurrence during primary treatment were more likely to have EWB decline (OR 0.53, 95 % CI 0.32-0.87). Greater perceived likelihood of recurrence (OR 1.95, 95 % CI 1.01-5.29) and increased worry about recurrence (OR 1.38, 95 % CI 1.10-1.72) were associated with EWB decline. Higher spirituality beliefs and practices were associated with EWB decline. CONCLUSIONS: A considerable number of breast cancer patients report emotional well-being declines over time. Early identification of women who are vulnerable, such as women with past depression, is crucial to improve quality of care. Women would benefit from education about cancer recurrence and tailored strategies to manage worry about recurrence over time. IMPLICATION FOR CANCER SURVIVORS: Understanding actual risk of recurrence and managing worry about recurrence is important for cancer survivors. Emotional concerns are common for individuals with cancer so survivors should feel free to reach out and discuss such concerns with providers well into the survivorship period.

RESUMO

BACKGROUND: While randomized controlled trials represent the highest level of evidence we can generate in comparative effectiveness research, there are clinical scenarios where this type of study design is not feasible. The Comparative Effectiveness Analyses of Surgery and Radiation in localized prostate cancer (CEASAR) study is an observational study designed to compare the effectiveness and harms of different treatments for localized prostate cancer, a clinical scenario in which randomized controlled trials have been difficult to execute and, when completed, have been difficult to generalize to the population at large. METHODS: CEASAR employs a population-based, prospective cohort study design, using tumor registries as cohort inception tools. The primary outcome is quality of life after treatment, measured by validated instruments. Risk adjustment is facilitated by capture of traditional and nontraditional confounders before treatment and by propensity score analysis. RESULTS: We have accrued a diverse, representative cohort of 3691 men in the USA with clinically localized prostate cancer. Half of the men invited to participate enrolled, and 86% of patients who enrolled have completed the 6-month survey. CONCLUSION: Challenging comparative effectiveness research questions can be addressed using well-designed observational studies. The CEASAR study provides an opportunity to determine what treatments work best, for which patients, and in whose hands.

RESUMO

Adjuvant endocrine therapy for breast cancer reduces recurrence and improves survival rates. Many patients never start treatment or discontinue prematurely. A better understanding of factors associated with endocrine therapy initiation and persistence could inform practitioners how to support patients. We analyzed data from a longitudinal study of 2,268 women diagnosed with breast cancer and reported to the Metropolitan Detroit and Los Angeles SEER cancer registries in 2005-2007. Patients were surveyed approximately both 9 months and 4 years after diagnosis. At the 4-year mark, patients were asked if they had initiated endocrine therapy, terminated therapy, or were currently taking therapy (defined as persistence). Multivariable logistic regression models examined factors associated with initiation and persistence. Of the 743 patients eligible for endocrine therapy, 80 (10.8 %) never initiated therapy, 112 (15.1 %) started therapy but discontinued prematurely, and 551 (74.2 %) continued use at the second time point. Compared with whites, Latinas (OR 2.80, 95 % CI 1.08-7.23) and black women (OR 3.63, 95 % CI 1.22-10.78) were more likely to initiate therapy. Other factors associated with initiation included worry about recurrence (OR 3.54, 95 % CI 1.31-9.56) and inadequate information about side effects (OR 0.24, 95 % CI 0.10-0.55). Factors associated with persistence included two or more medications taken weekly (OR 4.19, 95 % CI 2.28-7.68) and increased age (OR 0.98, 95 % CI 0.95-0.99). Enhanced patient education about potential side effects and the effectiveness of adjuvant endocrine therapy in improving outcomes may improve initiation and persistence rates and optimize breast cancer survival.

RESUMO

INTRODUCTION: Inflammatory breast cancer (IBC) is characterized by an apparent geographical distribution in incidence, being more common in North Africa than other parts of the world. Despite the rapid growth of immigrants to the United States from Arab nations, little is known about disease patterns among Arab Americans because a racial category is rarely considered for this group. The aim of this study was to advance our understanding of the burden of IBC in Arab ethnic populations by describing the proportion of IBC among different racial groups, including Arab Americans from the Detroit, New Jersey and California Surveillance, Epidemiology and End Results (SEER) registries. METHODS: We utilized a validated Arab surname algorithm to identify women of Arab descent from the SEER registries. Differences in the proportion of IBC out of all breast cancer and IBC characteristics by race and menopausal status were evaluated using chi-square tests for categorical variables, t-tests and ANOVA tests for continuous variables, and log-rank tests for survival data. We modeled the association between race and IBC among all women with breast cancer using hierarchical logistic regression models, adjusting for individual and census tract-level variables. RESULTS: Statistically significant differences in the proportion of IBC out of all breast cancers by race were evident. In a hierarchical model, adjusting for age, estrogen and progesterone receptor, human epidermal growth receptor 2, registry and census-tract level education, Arab-Americans (OR=1.5, 95% CI=1.2,1.9), Hispanics (OR=1.2, 95% CI=1.1,1.3), Non-Hispanic Blacks (OR=1.3, 95% CI=1.2, 1.4), and American Indians/Alaskans (OR=1.9, 95% CI=1.1, 3.4) had increased odds of IBC, while Asians (OR=0.6, 95% CI=0.6, 0.7) had decreased odds of IBC as compared to Non-Hispanic Whites. CONCLUSIONS: IBC may be more common among certain minority groups, including Arab American women. Understanding the descriptive epidemiology of IBC by race may generate hypotheses about risk factors for this aggressive disease. Future research should focus on etiologic factors that may explain these differences.

RESUMO

OBJECTIVE: This cross sectional study aimed to characterize fears of recurrence among women newly diagnosed with gynecologic cancer. The study also evaluated models predicting the impact of recurrence fears on psychological distress through social and cognitive variables. METHODS: Women (N=150) who participated in a randomized clinical trial comparing a coping and communication intervention to a supportive counseling intervention to usual care completed baseline surveys that were utilized for the study. The survey included the Concerns about Recurrence Scale (CARS), Beck Depression Inventory (BDI), Impact of Event Scale (IES), and measures of social (holding back from sharing concerns and negative responses from family and friends) and cognitive (positive reappraisal, efficacy appraisal, and self-esteem appraisal) variables. Medical data was obtained via medical chart review. RESULTS: Moderate-to-high levels of recurrence fears were reported by 47% of the women. Younger age (p<.01) and functional impairment (p<.01) correlated with greater recurrence fears. A social-cognitive model of fear of recurrence and psychological distress was supported. Mediation analyses indicated, that as a set, the social and cognitive variables mediated the association between fear of recurrence and both depression and cancer-specific distress. Holding back and self-esteem showed the strongest mediating effects. CONCLUSION: Fears of recurrence are prevalent among women newly diagnosed with gynecologic cancer. Social and cognitive factors play a role in women's adaptation to fears and impact overall psychological adjustment. These factors may be appropriate targets for intervention.

RESUMO

BACKGROUND AND PURPOSE: While variation in breast cancer quality indicators has been studied, to date there have been no studies examining the degree of surgeon-level variation in patient-reported outcomes. The purpose of this study is to examine surgeon-level variation in patient appraisals of their breast cancer care experiences. METHODS: Survey responses and clinical data from breast cancer patients reported to Detroit and Los Angeles Surveillance, Epidemiology and End Results registries from 6/2005 to 2/2007 were merged with attending surgeon surveys (1,780 patients, 291 surgeons). Primary outcomes were patient reports of access to care, care coordination, and decision satisfaction. Random-effects models examined variation due to individual surgeons for these three outcomes. RESULTS: Mean values on each patient-reported outcome scale were high. The amount of variation attributable to individual surgeons in the unconditional models was low to modest: 5.4% for access to care, 3.3% for care coordination, and 7.5% for decision satisfaction. Few factors were independently associated with patient reports of better access to or coordination of care, but less-acculturated Latina patients had lower decision satisfaction. CONCLUSIONS: Patients reported generally positive experiences with their breast cancer treatment, though we found disparities in decision satisfaction. Individual surgeons did not substantively explain the variation in any of the patient-reported outcomes.

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: The national obesity epidemic is contributing to an increased proportion of overweight and obese breast cancer patients. The authors' purpose was to determine whether patterns of use and outcomes of reconstruction differed among obese and nonobese patients. METHODS: The authors performed a 5-year follow-up survey of mastectomy-treated breast cancer patients from the Los Angeles and Detroit Surveillance, Epidemiology and End Results Cancer Registries (response rate, 59 percent). Patients were divided into three body mass index categories: normal weight (body mass index<25 kg/m), overweight (25 to 30 kg/m), and obese (>30 kg/m). Outcomes of interest were receipt of reconstruction, type and timing of reconstruction, access barriers, and satisfaction. Chi-square and t tests were used for analysis. Logistic regression was used to identify predictors of autologous reconstruction. RESULTS: Of 374 mastectomy-treated patients, receipt of reconstruction did not vary by body mass index (53 percent normal weight, 48 percent overweight, and 45 percent obese; p=0.43). Receipt did vary by type of reconstruction: significantly more obese patients received transverse rectus abdominis musculocutaneous flaps compared with normal weight patients (53 percent versus 26 percent; p=0.01). No specific access barriers to reconstruction were identified. Patient satisfaction with surgical decision-making and surgical outcomes was similar across body mass index categories. CONCLUSIONS: Obese compared with normal weight breast cancer patients have similar use of breast reconstruction, are more likely to receive an autologous procedure, and report similar satisfaction with surgical outcomes. Future efforts should be directed at decreasing the surgical risk in this challenging patient population. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.

RESUMO

BACKGROUND: Surveillance, Epidemiology, and End Results (SEER) registry data have been used to suggest underuse and disparities in receipt of radiotherapy. Prior studies have cautioned that SEER may underascertain radiotherapy but lacked adequate representation to assess whether underascertainment varies by geography or patient sociodemographic characteristics. The authors sought to determine rates and correlates of underascertainment of radiotherapy in recent SEER data. METHODS: The authors evaluated data from 2290 survey respondents with nonmetastatic breast cancer, aged 20 to 79 years, diagnosed from June of 2005 to February 2007 in Detroit and Los Angeles and reported to SEER registries (73% response rate). Survey responses regarding treatment and sociodemographic factors were merged with SEER data. The authors compared radiotherapy receipt as reported by patients versus SEER records. The authors then assessed correlates of radiotherapy underascertainment in SEER. RESULTS: Of 1292 patients who reported receiving radiotherapy, 273 were coded as not receiving radiotherapy in SEER (underascertained). Underascertainment was more common in Los Angeles than in Detroit (32.0% vs 11.25%, P < .001). On multivariate analysis, radiotherapy underascertainment was significantly associated in each registry (Los Angeles, Detroit) with stage (P = .008, P = .026), income (P < .001, P = .050), mastectomy receipt (P < .001, P < .001), chemotherapy receipt (P < .001, P = .045), and diagnosis at a hospital that was not accredited by the American College of Surgeons (P < .001, P < .001). In Los Angeles, additional significant variables included younger age (P < .001), nonprivate insurance (P < .001), and delayed receipt of radiotherapy (P < .001). CONCLUSIONS: SEER registry data as currently collected may not be an appropriate source for documentation of rates of radiotherapy receipt or investigation of geographic variation in the radiation treatment of breast cancer.

RESUMO

PURPOSE: To assess whether radiation oncologists and surgeons differ in their attitudes regarding the local management of breast cancer, and to examine coordination of care between these specialists. METHODS AND MATERIALS: We surveyed attending surgeons and radiation oncologists who treated a population-based sample of patients diagnosed with breast cancer in metropolitan Detroit and Los Angeles. We identified 419 surgeons, of whom 318 (76%) responded, and 160 radiation oncologists, of whom 117 (73%) responded. We assessed demographic, professional, and practice characteristics; challenges to coordinated care; and attitudes toward management in three scenarios. RESULTS: 92.1% of surgeons and 94.8% of radiation oncologists indicated access to a multidisciplinary tumor board. Nevertheless, the most commonly identified challenge to radiation oncologists, cited by 27.9%, was failure of other providers to include them in the treatment decision process early enough. Nearly half the surgeons (49.7%) stated that few or almost none of the breast cancer patients they saw in the past 12 months had consulted with a radiation oncologist before undergoing definitive surgery. Surgeons and radiation oncologists differed in their recommendations in management scenarios. Radiation oncologists were more likely to favor radiation than were surgeons for a patient with 3/20 lymph nodes undergoing mastectomy (p = 0.03); surgeons were more likely to favor more widely clear margins after breast conservation than were radiation oncologists (p = 0.001). CONCLUSIONS: Despite the widespread availability of tumor boards, a substantial minority of radiation oncologists indicated other providers failed to include them in the breast cancer treatment decision-making process early enough. Earlier inclusion of radiation oncologists may influence patient decisions, and interventions to facilitate this should be considered.
