The excess burden of breast carcinoma in minority and medically underserved communities: application, research, and redressing institutional racism

Association between hospital safety-net burden and receipt of trimodality therapy and survival for patients with esophageal cancer

BACKGROUND

To examine the relationship between hospital safety-net burden and (1) receipt of surgery after chemoradiation (trimodality therapy) and (2) survival in esophageal cancer patients.

METHODS

The National Cancer Database was queried to identify 22,842 clinical stage II to IVa esophageal cancer patients diagnosed in 2004 to 2015. The treatment facilities were categorized by proportion of uninsured/Medicaid-insured patients into percentiles. No safety-net burden hospitals (0-37th percentile) treated no uninsured/Medicaid-insured patients, whereas low (38-75th percentile) and high (76-100th percentile) safety-net burden hospitals treated a median (range) of 8.8% (0.87%-16.7%) and 23.6% (16.8%-100%), respectively. Adjusted odds ratios and hazard ratios with 95% confidence intervals were computed, adjusting for patient, tumor, and treatment characteristics.

RESULTS

Compared to no safety-net burden hospital patients, high safety-net burden hospital patients were significantly more likely to be young, Black, and low-income. Age, female sex, Black race, Hispanic ethnicity, nonprivate insurance, lower income, higher comorbidity score, upper esophageal location, squamous cell histology, higher stage, time to treatment, and treatment at a community program or a low-volume facility were associated with lower odds of receiving trimodality therapy. Adjusting for these factors, high safety-net burden hospital patients were less likely to receive surgery after chemoradiation versus no safety-net burden hospital patients (adjusted odds ratio 0.77 [95% confidence interval 0.68-0.86], P < .0001); no difference was detected comparing low safety-net burden hospitals versus no safety-net burden hospitals (adjusted odds ratio 1.01 [0.92-1.11], P = .874). No significant survival difference was noted by safety-net burden (low safety-net burden hospitals versus no safety-net burden hospitals: adjusted hazard ratio 1.01 [0.96-1.06], P = .704; high safety-net burden hospital versus no safety-net burden hospitals: adjusted hazard ratio 0.99 [0.93-1.06], P = .859).

CONCLUSION

Adjusting for patient, tumor, and treatment factors, high safety-net burden hospital patients were less likely to undergo surgery after chemoradiation but without significant survival differences.

The Experience of Informal Newcomer Cancer Caregivers with Limited Language Proficiency: A Scoping Review

This scoping review explored what is known about the experiences of informal cancer caregivers (CGs) who are newcomers with limited language proficiency. A literature search was performed in seven databases and the search yielded 11,289 articles. After duplicate removal and title and abstract screening, 216 articles underwent full text review and 57 articles and were synthesized. Most studies (n = 41, 72%) were qualitative and were published in North America (n = 35, 61%). Most CG participants were female (69%) and only 19 studies explicitly identified the CG country of origin. Of those that did, 26% originated from Asia, with most migrating from East Asia. Significant challenges were experienced by newcomer CGs and chief among these were related to communication challenges with HCPs that were exacerbated by a lack of availability of medical interpreters and the complexity of oncology health information. Efforts are needed to better integrate newcomer CGs into cancer care.

How Does Patient Socioeconomic Position Affect Breast Cancer Surgical Treatment and Mortality?: A Rapid Review

Background

Breast cancer is the second leading cause of death in women across the world. Despite significant improvements in overall breast cancer survival, disparities still exist. Research shows that socioeconomic position (SEP) plays a strong role in disparities in breast cancer care. Lower SEP can be a predictor of poorer breast cancer health outcomes and treatment received. No recent review has focused on SEP and breast cancer surgery outcomes. We conducted a rapid review assessing how patient SEP affects breast cancer surgical outcomes.

Methods

We developed and ran the search strategy in Ovid MEDLINE in January 2021. We assessed study eligibility using an adapted version of PICOS criteria. We included observational studies that assessed the relationship between SEP and breast cancer surgery treatment, including outcomes like surgery choice, survival, and wait time to surgery. We independently reviewed each article and independently extracted data using a pre-designed form. One reviewer narratively synthesized the data extracted from the included articles.

Results

We found twelve articles that met inclusion criteria. Eight out of 12 articles showed a difference in breast cancer surgery outcomes based on at least one measure of SEP. Six out of eight articles that collected surgery choice data found that women with lower SEP had lower rates of breast conserving surgery. One out of three articles that collected survival data found that higher SEP had a positive effect on survival. Additionally, one article that collected wait time to surgery data found a significant correlation between lower SEP and longer delays to surgical treatment.

Conclusion

In conclusion, our rapid review of SEP and breast cancer surgery outcomes found that there is a relationship between SEP and breast cancer surgery choice. This rapid review did not find enough evidence to see a relationship with overall survival and wait time to surgery.

Equity across the cancer care continuum for culturally and linguistically diverse migrants living in Australia: a scoping review

International evidence suggests migrants experience inequitable access, outcomes and treatment quality across the cancer care continuum. There is currently limited research assessing equity across the cancer care continuum for culturally and linguistically diverse migrants living in Australia. A detailed protocol and search strategy were developed and used to identify all relevant literature, utilising the Joanna Briggs Institute Reviewer’s Manual. Systematic searching was conducted via multiple databases and identified studies were screened against pre-identified inclusion and exclusion criteria. 71 studies met the inclusion criteria for analysis. Most studies examined cancer detection via screening. Very few studies examined cancer prevention, diagnosis, treatment or palliative care. Most studies focused on patient-sided barriers to care and there was a paucity of information regarding institutional barriers to health. Cancer-related outcomes were seldom examined, and most studies were qualitative or behavioral analysis. Results highlighted significant communication issues spanning the cancer care continuum and a context of inadequate support for both patients and clinicians. There is a demonstrable need to examine equity in access and outcomes for culturally and linguistically diverse cancer populations. This requires the identification of cancer-related disparities and an examination of institutional barriers to care. Through addressing this dearth of information, future research and health policy can support the operationalisation of health equity.

What matters most: protocol for a randomized controlled trial of breast cancer surgery encounter decision aids across socioeconomic strata

Background

Breast cancer is the most commonly diagnosed malignancy in women. Mastectomy and breast-conserving surgery (BCS) have equivalent survival for early stage breast cancer. However, each surgery has different benefits and harms that women may value differently. Women of lower socioeconomic status (SES) diagnosed with early stage breast cancer are more likely to experience poorer doctor-patient communication, lower satisfaction with surgery and decision-making, and higher decision regret compared to women of higher SES. They often play a more passive role in decision-making and are less likely to undergo BCS. Our aim is to understand how best to support women of lower SES in making decisions about early stage breast cancer treatments and to reduce disparities in decision quality across socioeconomic strata.

Methods

We will conduct a three-arm, multi-site randomized controlled superiority trial with stratification by SES and clinician-level randomization. At four large cancer centers in the United States, 1100 patients (half higher SES and half lower SES) will be randomized to: (1) Option Grid, (2) Picture Option Grid, or (3) usual care. Interviews, field-notes, and observations will be used to explore strategies that promote the interventions’ sustained use and dissemination. Community-Based Participatory Research will be used throughout. We will include women aged at least 18 years of age with a confirmed diagnosis of early stage breast cancer (I to IIIA) from both higher and lower SES, provided they speak English, Spanish, or Mandarin Chinese. Our primary outcome measure is the 16-item validated Decision Quality Instrument. We will use a regression framework, mediation analyses, and multiple informants analysis. Heterogeneity of treatment effects analyses for SES, age, ethnicity, race, literacy, language, and study site will be performed.

Discussion

Currently, women of lower SES are more likely to make treatment decisions based on incomplete or uninformed preferences, potentially leading to poorer decision quality, quality of life, and decision regret. This study hopes to identify solutions that effectively improve patient-centered care across socioeconomic strata and reduce disparities in decision and care quality.

Impact of Different Sociodemographic Factors on Mental Health Status of Female Cancer Patients Receiving Chemotherapy for Recurrent Disease

Context:

Deterioration in mental health and poor quality of life (QOL) among women suffering from breast and ovarian cancer is not a direct result of the illness but mediated by many other psychosocial variables.

Aims:

The study intended to examine if there was any effect of educational level, residential status, family type, duration of treatment, and income level of family on anxiety, depression, and QOL among the breast and ovarian cancer patients, undergoing second- or subsequent-line chemotherapy.

Subjects and Methods:

Forty married female cancer patients with breast and ovarian cancer, aging between 40 and 60 years, education level ranges from no formal education to postgraduate degree, income level ranges from Rs. 1000 per month to Rs. 20000 per month, and undergoing second- or subsequent-line chemotherapy for the past 1–10 years were studied. Levels of anxiety and depression were determined by Hospital Anxiety and Depression Scale. The QOL was measured by using WHO QOLBREF scale.

Statistical Analysis Used:

Mean and standard deviation and Levene's F values were calculated. If Levene's F value was significant, then Mann–Whitney U-test was done or else independent samples t-test was used.

Results:

Among all the variables, education, residential status, and income affect significantly on anxiety, depression, and QOL.

Conclusions:

Early detection of psychosocial variables is essential for better screening of the cancer patients undergoing chemotherapy, and therefore, further psychological intervention can be planned accordingly.

Understanding Quality-of-Life Issues in Chinese Women with Breast Cancer: A Qualitative Investigation

Little is known about the cultural beliefs and quality of life (QOL) of US-born and foreign-born Chinese women with breast cancer. We conducted individual semistructured qualitative interviews to explore the meaning of QOL, identify beliefs about cancer, and make comparison between US-born and foreign-born survivors. Women in this study identified the stigma of breast cancer that exists in the Asian community. They also described interpersonal support as central to a good QOL. However, when describing QOL, foreign-born Chinese women referred to wealth more frequently, while US-born Chinese women indicated friendship more frequently. The study findings support the need for culturally appropriate interventions that take into consideration the cancer-related beliefs and QOL of breast cancer survivors in the Chinese community.

Predictors of Surgery Types after Neoadjuvant Therapy for Advanced Stage Breast Cancer: Analysis from Florida Population-Based Cancer Registry (1996-2009)

PURPOSE

Despite the established guidelines for breast cancer treatment, there is still variability in surgical treatment after neoadjuvant therapy (NT) for women with large breast tumors. Our objective was to identify predictors of the type of surgical treatment: mastectomy versus breast-conserving surgery (BCS) in women with T3/T4 breast cancer who received NT.

METHODS

Population-based Florida Cancer Data System Registry, Florida’s Agency for Health Care Administration, and US census from 1996 to 2009 were linked for women diagnosed with T3/T4 breast cancer and received NT followed by either BCS or mastectomy. Analysis of multiple variables, such as sociodemographic characteristics (race, ethnicity, socioeconomic status, age, marital status, and urban/rural residency), tumor’s characteristics (estrogen/progesterone receptor status, histology, grade, SEER stage, and regional nodes positivity), treatment facilities (hospital volume and teaching status), patients’ comorbidities, and type of NT, was performed.

RESULTS

Of 1,056 patients treated with NT for T3/T4 breast cancer, 107 (10%) had BCS and 949 (90%) had mastectomy. After adjusting with extensive covariables, Hispanic patients (adjusted odds ratio (aOR) = [3.50], 95% confidence interval (CI): 1.38–8.84, P = 0.008) were more likely to have mastectomy than BCS. Compared to localized SEER stage, regional stage with direct extension (aOR = [3.24], 95% CI: 1.60–6.54, P = 0.001), regional stage with direct extension and nodes (aOR = [4.35], 95% CI: 1.72–11.03, P = 0.002), and distant stage (aOR = [4.44], 95% CI: 1.81–10.88, P = 0.001) were significantly more likely to have mastectomy than BCS. Compared to patients who received both chemotherapy and hormonal therapy, patients who received hormonal NT only (aOR = [0.29], 95% CI: 0.12–0.68, P = 0.004) were less likely to receive mastectomy.

CONCLUSION

Our study suggests that Hispanic ethnicity, advanced SEER stage, and type of NT are significant predictors of receiving mastectomy after NT.

Breast cancer screening patterns among military beneficiaries: racial variations in screening eliminated in an equal-access model

BACKGROUND

African American women present with more aggressive breast tumors and at later stages than white women. Many factors have been proposed to explain these findings, including socioeconomic status, cultural beliefs, and access to medical care. The purpose of this project was to determine if stage at presentation would be equivalent in a system providing equal access to care and if screening was equivalent.

METHODS

The Naval Medical Center San Diego (NMCSD) tumor registry from 2007 to 2012 was queried for this cross-sectional study. Eligible women included all those diagnosed and treated for breast cancer at NMCSD. Distribution of tumor stage (early vs. advanced) between racial groups was compared by age, treatment, and receptor status.

RESULTS

A total of 624 women were eligible; 88 % were early stage (0-II) and 12 % presented with advanced stage (III or IV). Racial differences in distribution were significant among African American and Hispanic women for early versus advanced presentation (p = 0.011). No racial disparity was seen in screening patterns among women.

CONCLUSIONS

In a military health system with equal access to care and standard screening recommendations, screening patterns did not vary with race but did vary with stage and active duty status. African American women present with breast cancer at later stages and with more hormone-receptor negative tumors, suggesting that biology rather than socioeconomic or access factors may be the most important determinant of stage at presentation of breast cancer for African American women.

Body size across the life course and risk of premenopausal and postmenopausal breast cancer in Black women, the Carolina Breast Cancer Study, 1993-2001

BACKGROUND

It is believed that greater adiposity is associated with reduced risk of breast cancer in premenopausal but increased risk in postmenopausal women. However, few studies have evaluated these relationships among Black women or examined anthropometric measures other than near-diagnosis body mass index (BMI).

PURPOSE

This study investigated associations between measures of body size across the life course and breast cancer risk among Black and White women living in the US South.

METHODS

We used data from the Carolina Breast Cancer Study, a population-based case-control study of invasive breast cancer in North Carolina women aged 20-74 years. We assessed nine body size variables, including age 10 relative weight; age 18 BMI; adult weight gain; "reference" BMI 1 year before interview; and post-diagnosis measured BMI and abdominal obesity measures.

RESULTS

Among premenopausal Whites, heavier childhood relative weight was associated with decreased cancer risk [odds ratio (OR) 0.48 95 % confidence interval 0.33-0.70]. Among premenopausal Blacks, greater adult waist circumference and waist-to-hip ratio (WHR) were associated with increased risk [waist OR 1.40 (1.00-1.97) and high tertile WHR OR 2.03 (1.29-3.19)], with associations for WHR in a similar direction in Whites. Among postmenopausal women, recalled body size was not associated with risk, except for increased risk associated with adult weight gain among White non-hormone therapy users. ER/PR status and hormone therapy use also modified other associations.

DISCUSSION

In this population, greater adult BMI was not associated with increased breast cancer risk, but some measures of early-life body size and abdominal obesity were associated with risk.

Challenges to the control of breast cancer in a small developing country

OBJECTIVE

The aim of this study is to determine the clinicopathological features of breast cancer in two dedicated cancer treatment centers in north Trinidad. The histological types and stage at presentation were also investigated.

DESIGN AND METHODS

A retrospective cohort design was used; data were collected from a review of medical records of patients meeting the entry criteria. Clinical and demographic data were extracted.

RESULTS

A total of 640 patients were selected for the study and were available for the analysis. The annual cumulative incidence rate of breast cancer for the calendar years 2010 and 2011 in north Trinidad was 32.4 per 100,000 and 24.6 per 100,000 of the population. The age group between 51-60 years had the highest proportion of cases of breast cancer. There was a significant ethnic disparity in the occurrence of breast cancer, as it was more common in people of African origin than among South East Asians. Surgery and chemotherapy were the major interventions employed.

CONCLUSION

Breast cancer prevalence continues to be high in Trinidad; we provide evidence of the extent of and the degree of sophistication required to care for patients with breast cancer in a health care system in a small developing country.

Local breast cancer spatial patterning: a tool for community health resource allocation to address local disparities in breast cancer mortality

Despite available demographic data on the factors that contribute to breast cancer mortality in large population datasets, local patterns are often overlooked. Such local information could provide a valuable metric by which regional community health resources can be allocated to reduce breast cancer mortality. We used national and statewide datasets to assess geographical distribution of breast cancer mortality rates and known risk factors influencing breast cancer mortality in middle Tennessee. Each county in middle Tennessee, and each ZIP code within metropolitan Davidson County, was scored for risk factor prevalence and assigned quartile scores that were used as a metric to identify geographic areas of need. While breast cancer mortality often correlated with age and incidence, geographic areas were identified in which breast cancer mortality rates did not correlate with age and incidence, but correlated with additional risk factors, such as mammography screening and socioeconomic status. Geographical variability in specific risk factors was evident, demonstrating the utility of this approach to identify local areas of risk. This method revealed local patterns in breast cancer mortality that might otherwise be overlooked in a more broadly based analysis. Our data suggest that understanding the geographic distribution of breast cancer mortality, and the distribution of risk factors that contribute to breast cancer mortality, will not only identify communities with the greatest need of support, but will identify the types of resources that would provide the most benefit to reduce breast cancer mortality in the community.

Employment after a breast cancer diagnosis: a qualitative study of ethnically diverse urban women

Employment status is related to treatment recovery and quality of life in breast cancer survivors, yet little is known about return to work in immigrant and minority survivors. We conducted an exploratory qualitative study using ethnically cohesive focus groups of urban breast cancer survivors who were African-American, African-Caribbean, Chinese, Filipina, Latina, or non-Latina white. We audio- and video-recorded, transcribed, and thematically coded the focus group discussions and we analyzed the coded transcripts within and across ethnic groups. Seven major themes emerged related to the participants' work experiences after diagnosis: normalcy, acceptance, identity, appearance, privacy, lack of flexibility at work, and employer support. Maintaining a sense of normalcy was cited as a benefit of working by survivors in each group. Acceptance of the cancer diagnosis was most common in the Chinese group and in participants who had a family history of breast cancer; those who described this attitude were likely to continue working throughout the treatment period. Appearance was important among all but the Chinese group and was related to privacy, which many thought was necessary to derive the benefit of normalcy at work. Employer support included schedule flexibility, medical confidentiality, and help maintaining a normal work environment, which was particularly important to our study sample. Overall, we found few differences between the different ethnic groups in our study. These results have important implications for the provision of support services to and clinical management of employed women with breast cancer, as well as for further large-scale research in disparities and employment outcomes.

A review of body size and breast cancer risk in Hispanic and African American women

Obesity is an epidemic in the United States, especially among Hispanics and African Americans. Studies of obesity and breast cancer risk have been conducted primarily in non-Hispanic whites. There have been few studies of the association between body mass index (BMI) or weight gain and the risk of breast cancer in minorities, and the results have been inconsistent. Because most studies are conducted primarily in non-Hispanic whites, the etiology of breast cancer in minorities is not well understood. The authors of the current report reviewed the literature on the association between obesity, weight, and weight gain and breast cancer in minorities using a combination of the Medical Subject Heading (MeSH) terms "obesity," "body mass index," "weight," "weight gain," "Hispanic," and "African American." Only publications in English and with both risk estimates and 95% confidence intervals were considered. Forty-five studies of body size and breast cancer risk in non-Hispanic whites were identified. After an exhaustive search of the literature, only 3 studies of body size and breast cancer were conducted in Hispanic women were identified, and only 8 such studies in African American women were identified. The results were inconsistent in both race/ethnicity groups, with studies reporting positive, inverse, and null results. Thus, as obesity rates among Hispanics and African Americans continue to rise, there is an urgent need to identify the roles that both obesity and adult weight gain play in the development of breast cancer in these minorities. Additional studies are needed to provide more understanding of the etiology of this disease and to explain some of the disparities in incidence and mortality.

Impact of perceived racial discrimination on health screening in black women

Perceived discrimination has been shown to be related to health screening behavior. The present study examines the effect of discrimination on cancer screening among women in the Black Women's Health Study. Five self-report items measured discrimination in everyday life and three items measured experiences of major discrimination. Logistic regression was used to test associations of discrimination with Pap smear, mammography, or colonoscopy utilization. At the start of follow-up, 88.8% had a Pap smear in the previous year, 52.7% had a mammogram, and 20.0% had received a colonoscopy. Both everyday and major discrimination were associated with not having received a Pap smear, even after adjusting for other variables. Discrimination was not associated with mammography or colonoscopy utilization. In conclusion, perceived everyday and major discrimination is associated with poorer utilization of Pap smears for cervical cancer screening among Black women.

Racial/Ethnic differences in the health-related quality of life of cancer patients

Previous research has suggested that, when compared to European Americans (EAs), African Americans (AAs) are at higher risk of metastatic disease at time of cancer diagnosis, and a higher risk of shorter survival. Although AA patients have reported worse physical health than EA patients, studies have rarely addressed whether racial/ethnic disparities exist on the social, emotional, and functional aspects of health-related quality of life. Five hundred and two AA and 396 EA patients with AIDS-related malignancies or breast, colon, head/neck, and lung cancers seeking treatment within the contiguous United States and Puerto Rico participated in the present study. Responses on the Functional Assessment of Cancer Therapy-General were analyzed for possible racial/ethnic disparities using multivariable regression models and item response theory modeling to detect differential item functioning. Differential item functioning was found in six items of the Functional Assessment of Cancer Therapy-General, indicating that AA and EA participants had different probabilities of responding to these items. Compared to EAs at the same level of health-related quality of life, AAs reported more severe symptomatology on items that reflected malaise and ability to work, and less severe symptomatology on items that reflected fatigue, treatment side effects, and outlook on life. At the subscale level, AAs reported poorer physical and social well-being, but better emotional well-being, than EAs. Similar to previous studies, AA patients reported poorer physical functioning than a comparable group of EA patients. Some items appear to be responded to differently by AAs and EAs, suggesting it is important to consider race/ethnicity when evaluating responses to questions about health-related quality of life.

Understanding the role of reactions to race-based treatment in breast and cervical cancer screening

Racial and ethnic disparities in breast and cervical cancer mortality persist despite effective screening methods. We examined associations between race/ethnicity and Pap testing within three years or mammography within two years, controlling for a composite reactions-to-race-based-treatment variable created using data from the 2002 and 2004 Behavioral Risk Factor Surveillance System Reactions to Race module, which assessed respondents experiences based on one's race. We calculated prevalence of Pap testing (for women aged > or = 18) and mammography (for women aged > or = 40) by race, and fit logistic regression models to estimate the strength of association of reactions to race-based treatment with screening and race--before and after controlling for demographics, socioeconomic status, health status, smoking and healthcare access. In the reduced model, black women were more likely (2.03: 95% CI: 1.55-2.65) to be screened for cervical cancer than whites. Reactions to race-based treatment did not impact the odds of black women receiving Pap tests or mammograms. Given current racial and ethnic disparities in breast and cervical cancer mortality, we suggest that more attention needs to be focused on follow-up of abnormal results and state-of-the art treatment for black and Hispanic women.

Differences in predictors of cervical and breast cancer screening by screening need in uninsured Latina women

BACKGROUND

Latino women experience higher mortality for cervical cancer and lower 5-year survival for breast cancer than non-Latino White women. Adherence with screening recommendations can increase chances of survival, yet the factors that influence screening behaviors in uninsured women are not well documented.

METHODS

Uninsured Latino women (N = 467) recruited in four US cities participated in the study. Logistic regression was used to model adherence to recommendations by screening type (cervical or breast cancer) and screening need (needs to obtain initial screening, overdue for rescreening, up-to-date with rescreening).

RESULTS

Predictors differed by type of screening and screening need. Women who reported exposure to cancer education were more likely to have had a mammogram and to be up-to-date with Pap smear screening than women without such exposure. Women who were younger, had more than a sixth grade education, and/or had children were more likely to have had a Pap smear. Older women who had been in the US the longest were more likely to be overdue for a Pap smear. Women with incomes 5000 to 7000 were more likely to have obtained a mammogram. Regional differences were found with respect to mammography screening and maintenance behaviors.

CONCLUSIONS

Exposure to cancer education is an important predictor of screenings among uninsured urban Latino women. The potential of creating educational interventions that can increase screening rates among women who evidence health disparities is encouraging. Recruitment strategies to reach women in need of screenings are provided.

Disparities in Lung Cancer: Focus on Asian Americans and Pacific Islanders, American Indians and Alaska Natives, and Hispanics and Latinos

Significant population changes in the United States are expected over the next few decades. The changing demographics inclusive of native and newly native individuals will significantly impact health care because racial and ethnic groups vary widely in their risks for disease and approach to medical care. For lung cancer specifically, racial and ethnic groups differ in smoking habits, metabolism of nicotine, presentation, stage at diagnosis, treatment received, and outcomes. This article summarizes current information on lung cancer for American and Pacific Islanders, American Indians and Alaska natives,and Hispanics and Latinos with an emphasis on tobacco use, epidemiologic issues sur-rounding acculturation and assimilation, genetic epidemiology, and disparities in treatment outcomes.

Survival disadvantage among Medicaid-insured breast cancer patients treated with breast conserving surgery without radiation therapy

BACKGROUND

Clinical studies indicate that breast cancer patients treated with breast conserving surgery (BCS) without radiotherapy (RT) have a greater risk of recurrence and mortality compared to those receiving BCS plus RT. However, this relationship has been underdeveloped among low-income women in the community who may face barriers in accessing adjuvant treatment and post-treatment surveillance. It is possible that the prognostic significance of omission of RT in clinical trials underestimates the significance of risk in the community.

METHODS

Using cancer registry, Medicaid claims, and the Social Security Master Death File, we evaluated receipt of RT in women with early stage breast cancer treated with BCS and mean 6-year overall and cancer-specific survival. Logistic regression was used to assess correlates of RT. The Kaplan-Meier method was used to determine survival by RT status and a multivariate Cox proportional hazards regression was used to evaluate the role of RT status on overall and cause-specific survival.

RESULTS

A total of 65% of women received RT, and 82% of the sample survived the study period. Death rates of 16% and 51% were observed among those who did and did not receive RT, respectively (P < 0.001). One-third of women who died from cancer (8 of 24) received radiation. Use of RT was associated with a statistically significant decrease in all-cause (hazard ratio = 0.42, 95% CI 0.21-0.85) and cancer-specific mortality (hazard ratio = 0.22, 95% CI -0.09 to 0.57).

CONCLUSIONS

Adjuvant radiation following BCS was underused in this sample of poor breast cancer patients. Lack of adjuvant RT may be a proxy for inadequate access to care and poor cancer surveillance after treatment.

Post-treatment symptoms among ethnic minority breast cancer survivors

PURPOSE/OBJECTIVES

To determine racial and ethnic differences in the range and number of post-treatment symptoms among women who have undergone surgical and postsurgical treatment for breast cancer.

DESIGN

Retrospective study.

SETTING

Community-based social services agency and public health clinic.

METHODS

Face-to-face interview of 116 women who had undergone breast cancer surgery.

SAMPLE

Primarily low-income women in an urban area in northern California. Participants were recruited via posted flyers regarding the study.

MAIN RESEARCH VARIABLES

Outcomes (depression, fatigue, pain, and swelling from lymphedema) and demographics (ethnicity, age, income, insurance, education, and marital status).

FINDINGS

The typical participant was 47 years old, had 12 years of education, and was a parent (74%), unmarried (67%), heterosexual (88%), uninsured (68%), and employed (66%). Thirty percent were Caucasian, 30% African American, 25% Latina, and 15% women of other ethnic backgrounds. African American women and Latinas reported increased rates of pain and an increased number of symptoms. Latinas also reported higher rates of fatigue and depression. In multivariate analyses, an increased number of symptoms were associated with decreased income, with receiving chemotherapy, with having a mastectomy, and with Latina ethnicity.

CONCLUSIONS

These data suggest an increased rate of post-treatment symptoms experienced by low-income and ethnic minority women.

IMPLICATIONS FOR NURSING

A need exists for affordable, culturally appropriate symptom management interventions. Nursing will have a vital role in designing, testing, and offering such interventions.

Factors that affect breast cancer treatment: underserved and minority populations

Breast cancer treatment in underserved populations continues to deviate from established guidelines. Significant barriers persist at the system, physician, and patient levels that ultimately may affect survival adversely. Successful strategies to reduce the disparities must be developed to improve outcomes in this population of women.

Health care disparities and cervical cancer

OBJECTIVES

We compared cervical cancer incidence, stage at diagnosis, and survival in Medicaid-insured and non-Medicaid-insured populations.

METHODS

We stratified the sample by age and used ordered logistic regression to predict stage at diagnosis and used Cox proportional hazards regression to predict survival.

RESULTS

Medicaid insured nearly one quarter of women diagnosed with cervical cancer. The likelihood of late-stage disease was greatest for women who enrolled in Medicaid after diagnosis. Women younger than 65 years who enrolled in Medicaid after diagnosis were more likely to die from cervical cancer than were women who were not insured by Medicaid (hazard ratio=2.40, 95% confidence interval=1.49, 3.86).

CONCLUSIONS

Our study underscores the importance of cervical cancer screening programs targeted at low-income women.

Race and family history assessment for breast cancer

OBJECTIVE

Studies have demonstrated disparities in breast cancer screening between racial and ethnic groups. Knowledge of a woman's family history of breast cancer is important for initiating early screening interventions. The purpose of this study was to determine whether differences exist in the collection of family history information based on patient race.

DESIGN

Cross-sectional patient telephone interview and medical record review.

SETTING

Eleven primary care practices in the Greater Boston area, all associated with Harvard Medical School teaching hospitals.

PARTICIPANTS

One thousand seven hundred fifty-nine women without a prior history of breast cancer who had been seen at least once by their primary care provider during the prior year.

MEASUREMENTS AND MAIN RESULTS

Data were collected on patients regarding self-reported race, family breast cancer history information, and breast cancer screening interventions. Twenty-six percent (462/1,759) of the sample had documentation within their medical record of a family history for breast cancer. On multivariate analysis, after adjusting for patient age, education, number of continuous years in the provider's practice, language, and presentation with a breast complaint, white women were more likely to be asked about a breast cancer family history when compared to nonwhite women (odds ratio, 1.68; 95% confidence interval, 1.21 to 2.35).

CONCLUSIONS

The majority of women seen by primary care providers do not have documentation of a family breast cancer history assessment within their medical record. White women were more likely to have family breast cancer information documented than nonwhites.

The interleukin-6 gene: a susceptibility factor that may contribute to racial and ethnic disparities in breast cancer mortality

Breast cancer prognosis differs among racial and ethnic groups. Though the incidence of breast cancer is lower in African-Americans than in Caucasians, mortality is higher. While socioeconomic, psychosocial, and lifestyle issues are undoubtedly important in such disparities, genetic factors that differ among populations and that are involved in the molecular pathways regulating tumor development may also play roles. In this communication, I summarize recent investigations of the gene encoding the pro-inflammatory cytokine interleukin-6 (IL-6), and suggest that this gene is a susceptibility factor that determines racial and/or ethnic differences in breast cancer survival. Published studies of a G/C polymorphism at nucleotide -174 within the promoter region of the IL-6 gene are consistent with this suggestion. This polymorphism alters expression of the cytokine. In addition, allele and genotype frequencies at the -174 site differ dramatically among racial and ethnic groups. Finally, the variant genotypes are associated with alterations in breast cancer survival. In all, these observations argue for additional studies of the IL-6 gene polymorphism as a predisposing genetic factor that contributes to racial and ethnic differences in breast cancer prognosis.

United States coronary mortality trends and community services associated with occupational structure, among blacks and whites, 1984-1998

This paper examines the association between US county occupational structure, services availability, prevalence of risk factors, and coronary mortality rates by sex and race, for 1984-1998. The 3137 US counties were classified into five occupational structure categories; counties with the lowest percentages of the labor force in managerial, professional, and technical occupations were classified in category I (5-16%), counties with the highest percentages were in category V (32-59%). Directly age-adjusted coronary heart disease (CHD) mortality rates, for aged 35-64 years, (from vital statistics and Census data), per-capita services (County Business Patterns), and the prevalence of CHD risk factors (Behavioral Risk Factor Surveillance Surveys data) were calculated for each occupational structure category. CHD mortality rates and the prevalence of risk factors were inversely monotonically associated with occupational structure categories for white men and women but not among black men and women. Numbers of producer services for banking, business credit, overall business services and personnel/employment services were 2-12 times greater in category V versus I counties. Consumer services such as fruit/vegetable markets, fitness facilities, doctor offices and social services were 1.6-3 times greater in category V versus I counties. Residential racial segregation scores remained high in most areas despite declines during 1980-1990; occupational segregation by race and gender were shown indicating continued institutional racism. An ecological model for conceptualizing communities and health and the overall influence of state and national occupational structure is discussed; intervention strategies such as decreased wage disparities and 'living wage' standards and development is discussed.

Understanding the breast cancer experience of women: a qualitative study of African American, Asian American, Latina and Caucasian cancer survivors

Breast cancer is the most common form of cancer in American women across most ethnic groups. Although the psychosocial impact of breast cancer is being studied, there is little information on women from diverse ethnic and socioeconomic backgrounds. We conducted a qualitative study with breast cancer survivors (BCS) of various ethnicities. A total of 102 BCS participated in focus group interviews (24 African Americans, 34 Asians, 26 Latinas and 18 Caucasians); 20 health professionals participated in key informant interviews. Important ethnic differences in type of treatment were noted, Asians and Latinas were more likely to receive mastectomies and African American BCS were least likely to receive adjuvant therapies, including radiation and chemotherapy. These BCS enjoyed a fairly good overall health-related quality of life (HRQOL) with some persistent concerns. The prevailing concerns among all women included overall health, moderate physical concerns, cancer recurrence or metastases, psychosocial concerns related to worry about children and burdening the family, and body image and sexual health concerns. Additional challenges included: lack of knowledge about breast cancer; medical care issues such as insurance, cost and amount of time spent with physician; cultural sensitivity of providers, language barriers, cultural factors related to beliefs about illness, gender role and family obligations (e.g. self-sacrifice). These BCS, particularly the women of color, voiced that their spiritual beliefs and practices are central to their coping. This study accomplishes two goals; it adds to the sparse literature concerning the psychosocial sequelae of breast cancer among women of color, and it increases our knowledge of specific cultural influences (e.g. dietary practices, coping) and socio-ecological factors on HRQOL. More importantly, the study addressed areas that have not been studied before, specifically, an in-depth study on BCS QOL comparing multiple ethnic groups in the US. The results of this investigation will provide preliminary information to survivors and health-care providers about the impact of culture and socio-ecological contexts on survivorship. Among women of all major ethnic groups, breast cancer is the most common form of cancer and the second leading cause of cancer death (American Cancer Society (ACS), 2002). In 2002, over 203,000 women in the United States will be diagnosed with breast cancer (ACS, 2002). Ethnic disparities exist for cancer stage, diagnosis, survival, morbidity and mortality. In general, ethnic minority women are diagnosed with more advanced disease and experience greater morbidity and mortality (Haynes & Smedley, 1999; Miller et al., 1996; Ries et al., 2000; Shinagawa, 2000). In general, increases in survival rates have prompted greater interest in the quality of life (QOL) of breast cancer survivors (BCS) over the past two decades. Additionally, the QOL of cancer survivors from diverse ethnic, cultural and socioeconomic backgrounds is an emerging priority area for studies on survivorship research and clinical care (Haynes and Smedley, 1999; National Cancer Institute (NCI), 2002; President's Cancer Panel, 2000).

Late stage cancers in a Medicaid-insured population

BACKGROUND

Medicaid insurance promotes screening for early stage cancers. However, previous research suggests that Medicaid recipients are at risk for late stage disease.

OBJECTIVE

To identify differences in stage of diagnosis between cancer patients enrolled in Medicaid before versus after their disease was identified, as well as differences in diagnostic stage between Medicaid enrollees and other patients.

DESIGN

Analyses of a linked database including information from the 1996 and 1997 Michigan Cancer Registry and Medicaid enrollment files.

PATIENTS

All persons ages 25 to 64 diagnosed with incident cases of breast, cervical, colorectal, or lung cancer (n = 5852). Patients enrolled in Medicaid before their cancer diagnosis and those enrolled in the same month or after their diagnosis were identified.

MAIN OUTCOME MEASURE

Early (in situ, local) versus late (regional, distant, invasive/unknown) cancer stage at diagnosis was modeled using multivariate logistic regression.

RESULTS

In each site of disease with the exception of breast, persons who enrolled in Medicaid after a cancer diagnosis were approximately 2 to 3 times more likely to have late stage disease compared with persons who were enrolled in Medicaid before the month of diagnosis. Odds ratios (OR) and 95% confidence intervals (C.I.) were: 1.28 (95% C.I. = 0.95, 1.67) for breast cancer, 2.96 (95% C.I. = 1.85, 4.75) for cervical cancer, 2.08 (95% C.I. = 1.30, 3.33) for colorectal cancer, and 3.40 (95% C.I. = 2.13, 5.43) for lung cancer. Relative to non-Medicaid enrollees, Medicaid enrollees were 2 to 5 times more likely to be diagnosed with late stage disease.

CONCLUSIONS

Cancer patients enrolled in Medicaid after their diagnosis were disproportionately likely to have late stage disease relative to patients previously enrolled in Medicaid or non-Medicaid enrollees.

Breast cancer and women's labor supply

OBJECTIVE

To investigate the effect of breast cancer on women's labor supply. DATE SOURCE/STUDY SETTING: Using the 1992 Health and Retirement Study, we estimate the probability of working using probit regression and then, for women who are employed, we estimate regressions for average weekly hours worked using ordinary least squares (OLS). We control for health status by using responses to perceived health status and comorbidities. For a sample of married women, we control for spouses' employer-based health insurance. We also perform additional analyses to detect selection bias in our sample.

PRINCIPAL FINDINGS

We find that the probability of breast cancer survivors working is 10 percentage points less than that for women without breast cancer. Among women who work, breast cancer survivors work approximately three more hours per week than women who do not have cancer. Results of similar magnitude persist after health status is controlled in the analysis, and although we could not definitively rule out selection bias, we could not find evidence that our results are attributable to selection bias.

CONCLUSIONS

For some women, breast cancer may impose an economic hardship because it causes them to leave theirjobs. However, for women who survive and remain working, this study failed to show a negative effect on hours worked associated with breast cancer. Perhaps the morbidity associated with certain types and stages of breast cancer and its treatment does not interfere with work.

Breast cancer survivorship: are African American women considered? A concept analysis

PURPOSE/OBJECTIVE

To apply Rodger's (1989) evolutionary view of concept analysis to the term "cancer survivorship" with a heightened focus on breast cancer and African American women.

DESIGN

Qualitative, concept analysis.

DATA SOURCES

50 references from the disciplines of nursing and medicine.

DATA SYNTHESIS

This analysis revealed that the concept of cancer survivorship is unique, evolving, and based on the meaning individuals give to a diagnosis of cancer and their experiences of living beyond the diagnosis.

CONCLUSIONS

The concept of breast cancer survivorship can be operationally defined as the process of living through the cancer experience beyond a breast cancer diagnosis. A crucial need exists to explore the meaning of cancer survivorship among African American women as a basis for culturally competent care.

IMPLICATIONS FOR NURSING

Nurses and other healthcare professionals must comprehend the meaning of breast cancer survivorship and its implications for cancer survivors. The meaning of cancer survivorship to African American and ethnic minority women must be explored. Culturally relevant cancer survivorship education and care should be provided for African American women and other cancer survivors of ethnic minorities as well as those involved in the women's social and healthcare world. Nurses and healthcare professionals must continue to advocate for health policies to improve the lived experiences of all cancer survivors.

Effective palliative care for minority ethnic groups: the role of a liaison worker

As the issue of equality of access to health-care services becomes more important, there is increasing concern that specialist palliative care services in the UK are under-used by minority ethnic groups (Haroon-Iqbal et al, 1995; Karim et al, 2000). Research into the provision of such services for black and minority ethnic communities identified a number of factors that contribute to a perceived low take-up of services (Hill and Penso, 1995). A strategy to promote ethnic and racial sensitivity in palliative care service delivery, and policies to improve access to, and take-up of, services was recommended. This article presents the important elements relating to equal access to specialist palliative care and the provision of culturally sensitive services, and examines the role of the Macmillan Ethnic Minorities Liaison Officer in the Bradford community palliative care team.

Disparities in cancer diagnosis and survival

BACKGROUND

Concern has been raised over the disproportionate cancer mortality among minority and low-income persons. The current study examined differences in disease stage at the time of diagnosis and subsequent survival for patients who are medically indigent compared with the rest of the population of cancer patients in Michigan.

METHODS

The authors linked three Michigan statewide data bases: the Cancer Registry, Medicaid enrollment files, and death certificates. The analysis focused on female breast, cervix, lung, prostate, and colon carcinoma, and differences were analyzed in the incidence, disease stage at the time of diagnosis, and survival between younger women and older women who were either insured or not insured by Medicaid. To estimate the risk of late stage diagnosis and death, the authors used logistic regression, controlling for age, race, and Medicaid enrollment. Ordered logit models also were used as a refinement of disease stage prediction.

RESULTS

Medically indigent persons had a disproportionately larger share of cancer. Persons age < 65 years who were insured by Medicaid had the greatest risk of late stage diagnosis and death across all five disease sites analyzed. African-American women had a greater risk of death from breast carcinoma compared with other women independent of Medicaid status. No interaction effects were found between age, race, and/or gender and Medicaid enrollment.

CONCLUSIONS

The results of this study showed that the disparities in cancer outcomes may be greater than previously thought and are consistent across disease sites. If advancements made in cancer control are to be shared by the low-income population, then improvements clearly are needed in cancer prevention, early detection, and treatment for the poor.
