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.
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.
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.
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.
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.
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.
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).
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.
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.
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.
Population-based cancer registry data from the Surveillance, Epidemiology, and End Results (SEER) Program at the National Cancer Institute are based on medical records and administrative information. ...Although SEER data have been used extensively in health disparities research, the quality of information concerning race, Hispanic ethnicity, and immigrant status has not been systematically evaluated. The quality of this information was determined by comparing SEER data with self-reported data among 13,538 cancer patients diagnosed between 1973-2001 in the SEER—National Longitudinal Mortality Study linked database. The overall agreement was excellent on race (κ = 0.90, 95% CI = 0.88-0.91), moderate to substantial on Hispanic ethnicity (κ = 0.61, 95% CI = 0.58-0.64), and low on immigrant status (κ = 0.21. 95% CI = 0.10, 0.23). The effect of these disagreements was that SEER data tended to under-classify patient numbers when compared to self-identifications, except for the non-Hispanic group which was slightly over-classified. These disagreements translated into varying racial-, ethnic-, and immigrant status-specific cancer statistics, depending on whether self-reported or SEER data were used. In particular, the 5-year Kaplan-Meier survival and the median survival time from all causes for American Indians/Alaska Natives were substantially higher when based on self-classification (59% and 140 months, respectively) than when based on SEER classification (44% and 53 months, respectively), although the number of patients is small. These results can serve as a useful guide to researchers contemplating the use of population-based registry data to ascertain disparities in cancer burden. In particular, the study results caution against evaluating health disparities by using birth-place as a measure of immigrant status and race information for American Indians/Alaska Natives.
Abstract 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.
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.
To present a normal range of cerebrospinal fluid (CSF) protein levels in a community-based population and to evaluate factors that contribute to CSF protein level variability.
Samples of CSF protein ...were obtained from participants aged 32 to 95 years who underwent lumbar puncture (LP) between November 1, 2007, and October 1, 2017, as part of the Mayo Clinic Study of Aging, a longitudinal, population-based study of residents of Olmsted County, Minnesota.
A total of 633 participants (58.1% male; 99.1% White; mean ± SD age, 70.9±11.6 years) underwent LP with recorded CSF protein level. Mean ± SD CSF protein level was 52.2±18.4 mg/dL (to convert to mg/L, multiply by 10), with a 95% reference interval of 24.0 to 93.4 mg/dL (range, 14.0-148.0 mg/dL). Spinal stenosis and arterial hypertension were associated with higher CSF protein levels on univariable analysis (P<.001). Increasing age, male sex, and diabetes were all independently associated with higher CSF protein levels on multivariable analysis (P<.001). In the 66 participants with repeated LPs within 2.5 years, the coefficient of repeatability was 26.1 mg/dL. Eleven participants (16.7%) had a CSF protein level difference of 20 mg/dL or more between serial LPs, and 4 (6.1%) had a difference of 25 mg/dL or more. There was a trend toward greater CSF protein level variability in patients with spinal stenosis (P=.054).
This large population-based study showed that CSF protein level can vary significantly among individuals. Elevated CSF protein level was independently associated with older age, male sex, and diabetes and is higher than listed in many laboratories. These findings emphasize the necessity of evidence-based reevaluation and standardization of CSF protein metrics.
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.
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.
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.
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.
