Investigating the role of county-level colorectal cancer screening rates on stage at diagnosis of colorectal cancer in rural Georgia.

BACKGROUND: To examine the impact of county-level colorectal cancer (CRC) screening rates on stage at diagnosis of CRC and identify factors associated with stage at diagnosis across different levels of screening rates in rural Georgia. METHODS: We performed a retrospective analysis utilizing data from 2004 to 2010 Surveillance, Epidemiology, and End Results Program. The 2013 United States Department of Agriculture rural-urban continuum codes were used to identify rural Georgia counties. The 2004-2010 National Cancer Institute small area estimates for screening behaviors were applied to link county-level CRC screening rates. Descriptive statistics and multinominal logistic regressions were performed. RESULTS: Among 4,839 CRC patients, most patients diagnosed with localized CRC lived in low screening areas; however, many diagnosed with regionalized and distant CRC lived in high screening areas (p-value = 0.009). In multivariable analysis, rural patients living in high screening areas were 1.2-fold more likely to be diagnosed at a regionalized and distant stage of CRC (both p-value < 0.05). When examining the factors associated with stage at presentation, Black patients who lived in low screening areas were 36% more likely to be diagnosed with distant diseases compared to White patients (95% CI, 1.08-1.71). Among those living in high screening areas, patients with right-sided CRC were 38% more likely to have regionalized disease (95% CI, 1.09-1.74). CONCLUSION: Patients living in high screening areas were more likely to have a later stage of CRC in rural Georgia. IMPACT: Allocating CRC screening/treatment resources and improving CRC risk awareness should be prioritized for rural patients in Georgia.

Commentary: Cancer Survivorship and Subclinical Myocardial Damage.

The rate of cardiovascular disease among cancer survivors is higher than in the general population. This difference is due to traditional cardiovascular disease (CVD) risk factors and also to the cardiotoxicity of cancer treatment. In a population-based cohort study of 3,512 men and women who were free of CVD at visit 5 of a large, community-based cohort study, Florido et al. (Am J Epidemiol. 2019;188(12):2188-2195) evaluated the association of cancer survivorship with subclinical myocardial damage, as assessed by elevated high-sensitivity cardiac troponin T (hs-cTnT). Cancer survivors had significantly higher odds of elevated hs-cTnT (odds ratio = 1.26, 95% confidence interval: 1.03, 1.53). Results were similar for survivors of non-sex-related and colorectal cancers. There was no association between survivorship from breast and prostate cancers and elevated hs-cTnT. The findings of Florido et al. indicate that survivors of some cancers might be more likely to have elevated hs-cTnT than patients without prior cancer. These findings have important implications because identifying cancer survivors who have elevated CVD risk is of paramount importance in order to prevent CVD manifestations such as heart attack, congestive heart failure, or stroke. Additional research is needed to clarify the associations of elevated hs-cTnT levels among survivors of specific cancer sites, stage at diagnosis, and histologic types.

Cardiovascular conditions and obesity among gynecologic cancer survivors: Results from the 2020 behavioral risk factor surveillance system survey.

BACKGROUND: With the increasing prevalence of gynecologic cancer and obesity, there is a growing population living with cardiovascular disease, obesity and gynecologic cancer concurrently or at risk of developing these disease states. METHODS: We examined cardiovascular (CV) conditions and obesity among 1824 gynecologic cancer survivors in a cross-sectional analysis, using data from the 2020 Behavioral Risk Factor Surveillance System (BRFSS). Univariate and multivariable logistic regression methods were used in the analysis. RESULTS: The prevalence of heart attack, CHD, and stroke were significantly higher (p < 0.001) among survivors of gynecologic and other cancer survivors compared to women with no history of cancer. However, no statistically significant differences were observed across gynecologic and other cancer survivors. The prevalence of obesity among gynecologic cancer survivors was significantly higher (p < 0.001) than that in the other two groups. While around one-third of the women with no history of cancer and survivors of other types of cancer were obese, obesity prevalence was nearly 13%-points higher among survivors of gynecologic cancer. In multivariate analysis, gynecologic cancer survivors were 2.7 times more likely to have a heart attack compared to those without any history of cancer. The odds of CHD and stroke among survivors of gynecologic cancer were respectively 3.4 and 2.7 times that of those with no history of cancer. The adjusted odds were also similar, though smaller in magnitude. Gynecologic cancer survivors were also more likely to be obese -1.8 times that of those with no cancer. CONCLUSIONS: Gynecologic cancer survivors are more likely than persons without a cancer history to have cardiovascular disease and other chronic illnesses, and they have a higher prevalence of heart attack, stroke, and obesity. These results underscore the sizeable opportunities for primary, secondary, and tertiary prevention of cardiovascular health conditions among gynecologic cancer survivors.

Predictors of unhealthy physical and mental days among informal cancer caregivers: results from the 2019 Behavioral Risk Factor Surveillance System survey.

BACKGROUND: Patients with cancer and cancer survivors commonly rely upon family members and friends to act as caregivers to help manage cancer treatment and the late effects of that treatment. Informal caregivers provide a variety of supportive functions for cancer patients, including emotional, informational, and functional support, and practical assistance with skilled care activities. OBJECTIVE: We examined predictors of unhealthy physical and mental days among informal cancer caregivers. Unhealthy days are an estimate of the overall number of days during the previous 30 days when the respondent felt that either his or her physical or mental health was not good. METHODS: Data were used from the 2019 Behavioral Risk Factor Surveillance System (BRFSS), a cross-sectional, population-based study. The participants were adults aged ≥ 18 years who provided regular care or assistance to a friend or family member who had cancer in the past 30 days. RESULTS: On average, caregivers who had a household income of less than $25,000 per year reported more (p < 0.05) unhealthy physical and mental days (during the last 30 days). Average reported number of mental unhealthy days was the highest for those who provided care for 2 or more years and 40 or more hours per week. Caregivers of Hispanic ethnicity had a greater risk of reporting unhealthy physical and mental days among those who provided care for 2 or more years. Among those who were providing care for 40 + h a week, caregivers from less wealthy households (income less than $50,000) were at greater risk of experiencing a larger number of unhealthy mental days. CONCLUSIONS: Informal cancer caregiving can be a stressful experience with potentially negative consequences for both psychological and physical health. Of particular concern are caregivers who are low-income or have limited financial resources.

Social needs and health-related quality of life among hematologic cancer survivors.

OBJECTIVES: Recent studies have examined social needs (social determinants of health) among cancer survivors, but studies have not specifically focused on patients with leukemia or lymphoma. We examined food insecurity and other social needs among hematologic cancer survivors, including individuals who had completed primary therapy for leukemia, lymphoma, or multiple myeloma. A particular focus of the study was on the relationship between social needs and health-related quality of life. METHODS: We conducted a postal survey of a multiethnic cohort of hematologic cancer survivors who reside in Augusta, GA, or the surrounding area and who had been treated at the Georgia Cancer Center. RESULTS: A total of 53 patients with a history of hematologic cancer (leukemia, lymphoma, or multiple myeloma) completed the survey (10.6% response rate). The mean age was 62.6 years. The participants were diverse according to annual household income and employment status. About two-thirds were white and almost one-third were African American. Five of 52 participants (9.6%) experienced food insecurity. Patients with food insecurity had poorer HRQOL compared with those who were food secure (63.3 vs. 87.33, p = 0.0308). A similar pattern was seen for those who had difficulty paying utility bills, those who had housing insecurity, and those who had to go without health care because of a lack of transportation. Overall, there was a statistically significant inverse association between HRQOL and number of social needs (p = 0.004). CONCLUSION: When caring for cancer survivors, social needs such as food insecurity and housing insecurity are important considerations for oncologists and primary care providers, especially when caring for patients with lower socioeconomic status and racial/ethnic minorities.

Knowledge of prostate cancer among African American men: A systematic review.

OBJECTIVE: Recent studies indicate that many African American men may not be making informed decisions about prostate cancer early detection. This is partly due to patients having limited knowledge about early detection of the disease. METHODS: The present review is based upon bibliographic searches in PubMed and CINAHL and relevant search terms. Articles (n = 235) published in English from 1993 through July 31, 2020 were identified using the following MESH search terms and Boolean algebra commands: prostate cancer and knowledge and African Americans. RESULTS: Forty-two articles were eligible for inclusion. The results of this literature review indicate that many African American men have inadequate knowledge of prostate cancer and prostate cancer early detection. Studies indicate that knowledge of prostate cancer is particularly low among older, less-educated, lower-income, and unmarried men, along with those who lack a regular physician or health insurance. Many African American men are unaware that they are at increased risk of prostate cancer because of their age or race. CONCLUSIONS: Culturally appropriate educational efforts are needed to inform African- American men about the pros and cons of prostate cancer early detection and about risk factors for the disease so that they can make an informed decision about whether prostate cancer early detection is right for them. Of particular concern is the prostate cancer knowledge of low-income and less-educated men, along with those who lack health care insurance or a regular provider.

Symptoms associated with comorbid diabetes among breast cancer survivors.

BACKGROUND: The symptoms experienced by women with diabetes overlap with those of women with breast cancer and diabetes can worsen breast cancer symptoms. Studying the impact of diabetes on symptoms experienced by women with breast cancer can contribute to assessment and intervention strategies and facilitate the management of symptoms in this patient population. METHODS: We analyzed data from a sample of 164 breast cancer patients in order to examine symptoms associated with comorbid diabetes. Data were collected by postal survey. RESULTS: A sizeable percentage of the women (23.8%) had a reported history of diabetes. African American women with breast cancer, those with an annual income less than $35,000, and those who were on disability were more likely to have comorbid diabetes (p < 0.05 in each instance). Breast cancer survivors with diabetes were more likely to report having major problems with their health than women without diabetes (p < 0.05). Compared to women without diabetes, breast cancer survivors with diabetes were also more likely to report preoccupation with being ill (p < 0.07) and tenderness at surgical site (p < 0.06), and the associations were of borderline significance. DISCUSSION: Cancer survivors who have diabetes experience more problems with their health and preoccupation with being ill than breast cancer survivors who lack a history of diabetes. Additional research is warranted to examine symptoms and problems in living among breast cancer survivors, particularly those who are African American.

Social determinants of colorectal cancer risk, stage, and survival: a systematic review.

BACKGROUND: Several social determinants of health have been examined in relation to colorectal cancer incidence, stage at diagnosis, and survival including income, education, neighborhood disadvantage, immigration status, social support, and social network. Colorectal cancer incidence rates are positively associated with income and other measures of socioeconomic status. In contrast, low socioeconomic status tends to be associated with poorer survival. METHODS: The present review is based upon bibliographic searches in PubMed and CINAHL and relevant search terms. Articles published in English from 1970 through April 1, 2019 were identified using the following MeSH search terms and Boolean algebra commands: colorectal cancer AND (incidence OR stage OR mortality) AND (social determinants OR neighborhood disadvantage OR racial discrimination OR immigration OR social support). RESULTS: This review indicates that poverty, lack of education, immigration status, lack of social support, and social isolation play important roles in colorectal cancer stage at diagnosis and survival. CONCLUSIONS: To address social determinants of colorectal cancer, effective interventions are needed that account for the social contexts in which patients live.

Social determinants of breast cancer risk, stage, and survival.

PURPOSE: Social determinants of health that have been examined in relation to breast cancer incidence, stage at diagnosis, and survival include socioeconomic status (income, education), neighborhood disadvantage, unemployment, racial discrimination, social support, and social network. Other social determinants of health include medical distrust, immigration, status, inadequate housing, food insecurity, and geographic factors such as neighborhood access to health services. Socioeconomic factors influence risk of breast cancer. For all racial/ethnic groups, breast cancer incidence rates tend to be positively associated with socioeconomic status. On the other hand, low socioeconomic status is associated with increased risk of aggressive premenopausal breast cancers as well as late stage of diagnosis and poorer survival. There are well-documented disparities in breast cancer survival by socioeconomic status, race, education, census-tract-level poverty, and access to health insurance and preventive care. Poverty is associated with other factors related to late stage at breast cancer diagnosis and poorer survival such as inadequate health insurance, lack of a primary care physician and poor access to health care. RESULTS: The results of this review indicate that social determinants such as poverty, lack of education, neighborhood disadvantage, residential segregation by race, racial discrimination, lack of social support, and social isolation play an important role in breast cancer stage at diagnosis and survival. CONCLUSION: To address these social determinants and eliminate cancer disparities, effective interventions are needed that account for the social and environmental contexts in which cancer patients live and are treated.

Home-based physical activity interventions for breast cancer patients receiving primary therapy: a systematic review.

PURPOSE: Breast cancer continues to be the leading cause of cancer in women in the US, so it is important to provide these women with good therapies. However, there are adverse effects to these therapies. Physical activity plays an important role in alleviating these adverse effects of breast cancer therapy. However, the effectiveness of home-based physical activity interventions such as walking programs has not been detailed by prior reviews. METHODS: This article reviews articles published to date to examine whether home-based physical activity interventions are effective in improving physical activity and other outcomes among breast cancer patients who are undergoing primary therapy for the disease. The present review is based upon bibliographic searches in PubMed and CINAHL and relevant search terms. Articles published in English from 1980 through February 28, 2019 were identified. A total of 360 article citations were identified in PubMed and non-duplicates in CINAHL. RESULTS: After screening the abstracts or full texts of these articles and reviewing the references of previous review articles, we found 15 studies that met the eligibility criteria. Four of the studies were pre/post-test trials, 10 were randomized controlled trials, and one study was an observational study. CONCLUSION: Results from studies published to date indicate that among women receiving primary breast cancer therapy, home-based physical activity programs have positive effects on physical functioning and symptoms such as fatigue. Among women receiving adjuvant chemotherapy or radiation therapy, home-based physical activity programs are effective in reducing symptoms and improving physical functioning. Additional studies are needed to clarify the impact of home-based physical therapy interventions on other outcomes including quality-of-life, bone mineral density, cognitive functioning, and chemotherapy-induced peripheral neuropathy.

Survivorship issues in older breast cancer survivors.

PURPOSE: Almost half of breast cancer survivors are aged ≥ 65 years and the proportion is likely to increase due to the aging of the population. The objectives of this article were to review studies of health outcomes among older breast cancer survivors ≥ 65 years to identify gaps in the published literature and offer suggestions for future research. METHODS: The present review is based upon bibliographic searches in PubMed and CINAHL and relevant search terms. Articles published in English from January 1, 1970 through October 1, 2018 were identified using the following MeSH search terms and Boolean algebra commands. RESULTS: This review has revealed that older breast cancer survivors cope with health issues related to cancer treatment and the aging process, including comorbidities, osteoporosis, symptoms, physical functioning, cognitive functioning, nutrition, and physical activity. CONCLUSIONS: Additional research is needed to examine therapeutic interventions to address the health conditions older breast cancer survivors are coping with. Particular focus of further research should be on the nutritional status and physical activity levels of older breast cancer survivors. Individualized nutrition plans and tailored physical activity programs for older survivors are needed that meet people where they are and that form habits.

The Association of Aromatic Amino Acids with Incident Hip Fracture, aBMD, and Body Composition from the Cardiovascular Health Study.

In 5187 persons from the Cardiovascular Health Study, there was no significant association of dietary intakes of aromatic amino acids (AAA) with areal BMD of the hip or body composition. However, those who had the lowest dietary intakes of AAA were at increased risk for incident hip fractures. Prior studies of the association of protein intake with osteoporosis are conflicting and have not directly examined the relationship of aromatic amino acids (AAA) with fractures, areal bone mineral density (aBMD), and body composition. We sought to determine the relationship of dietary intakes of AAA with osteoporosis parameters in elderly men and women. 5187 men and women aged ≥ 65 years from the Cardiovascular Health Study (CHS) with dietary intakes of AAA (tryptophan, phenylalanine, tyrosine) estimated by food frequency questionnaire (FFQ) were included. We examined the relationship between a one-time estimate of daily dietary AAA intake with risk of incident hip fractures over a median of 13.2 years of fracture follow-up. A subset (n = 1336) who had dual energy X-ray absorptiometry (DXA) performed were included in a cross-sectional analysis of the association of dietary AAA intake with aBMD of the total hip and measurements of body composition. In multivariable models adjusted for demographic and clinical variables, medication use, and diet, higher dietary AAA intake was not significantly associated with incident hip fractures. All hazard ratios (HR) were less than one (tryptophan, HR 0.14, 95% CI 0.01 to 1.89; phenylalanine, HR 0.60, 95% CI 0.23 to 1.55; tyrosine, HR 0.59, 95% CI 0.27 to 1.32), but confidence intervals were wide and included no difference. However, in post hoc analyses, the lowest quartile of intake for each AAA was associated with an increased risk for hip fracture compared to higher quartiles (p ≤ 0.047 for all). Dietary AAA intakes were not significantly associated with total hip aBMD or any measurements of body composition. Overall, there was no significant association of dietary AAA intake with hip fractures, aBMD of the hip, or body composition. However, there may be a subset of elderly individuals with low dietary intakes of AAA who are at increased for hip fractures.

Cancer survivorship care plans, financial toxicity, and financial planning alleviating financial distress among cancer survivors.

Concomitant with the increasing use of cancer care plans has been an increasing awareness of the potential for oncology care to result in long-term financial burdens and financial toxicity. Cancer survivors can benefit from information on support and resources to help them navigate the challenges after acute cancer treatment. While cancer survivorship plans could be a vehicle for patients to receive information on how to mitigate financial toxicity, cancer survivorship plans have typically not dealt with the financial impact of cancer treatment or follow-up care. Embedding information into cancer survivorship plans on how to reduce or avoid financial toxicity presents an opportunity to address a highly prevalent patient need. Patient-centered qualitative studies are needed to assess the type, format, and level of detail of the information provided.

Epidemiology of Breast Cancer in Women.

Epidemiologic studies have contributed importantly to current knowledge of environmental and genetic risk factors for breast cancer. Worldwide, breast cancer is an important cause of human suffering and premature mortality among women. In the United States, breast cancer accounts for more cancer deaths in women than any site other than lung cancer. A variety of risk factors for breast cancer have been well-established by epidemiologic studies including race, ethnicity, family history of cancer, and genetic traits, as well as modifiable exposures such as increased alcohol consumption, physical inactivity, exogenous hormones, and certain female reproductive factors. Younger age at menarche, parity, and older age at first full-term pregnancy may influence breast cancer risk through long-term effects on sex hormone levels or by other biological mechanisms. Recent studies have suggested that triple negative breast cancers may have a distinct etiology. Genetic variants and mutations in genes that code for proteins having a role in DNA repair pathways and the homologous recombination of DNA double stranded breaks (APEX1, BRCA1, BRCA2, XRCC2, XRCC3, ATM, CHEK2, PALB2, RAD51, XPD), have been implicated in some cases of breast cancer.

Determinants of adherence to physical activity guidelines among overweight and obese African American breast cancer survivors: implications for an intervention approach.

OBJECTIVE: Public health agencies encourage breast cancer survivors (BCSs) to follow their physical activity guidelines (PAGs). However, adherence to these guidelines is low. African American (AA) BCSs are more often overweight or obese and less likely than women of other races to report adherence to physical activity recommendations. This study examined socioeconomic, clinical, and psychosocial correlates with meeting PAGs. DESIGN: AA women diagnosed and treated for breast cancer and participating in a breast cancer support group (N = 193) completed a lifestyle assessment tool capturing demographic characteristics; breast cancer diagnosis and treatment history; health-related quality of life; weight history, including body mass index and post-diagnosis weight gain; and physical activity. Logistic regressions were used to determine if these covariates were associated with meeting [>8.3 metabolic equivalent task (MET) hr/wk]; partially meeting (4.15-8.3 MET hr/wk); or not meeting (<4.15 MET hr/wk) PAGs. RESULTS: Only 54% of AA BCSs reported meeting current PAGs. Participants reporting weight gain of ≤5 lbs post-diagnosis, and those who received surgical treatment for breast cancer were more likely to complete at least 8.3 MET hr/wk. Better physical functioning and lesser pain intensity were associated with meeting PAGs. CONCLUSION: Several factors influence physical activity behaviors and are likely to be important in developing effective interventions to assist AA survivors manage their weight. It is essential that providers and breast cancer support groups that assist survivors to remain physically active and to manage their weight should be aware of these factors. These findings may help generate hypotheses for future research to undergird efforts to increase physical activity among African American BCSs.

Advancing Uterine Cancer Survivorship Among African American Women.

BACKGROUND: Few studies have examined health behavior interventions for African American women who are uterine cancer survivors. Black-white differences in uterine cancer survival suggest that there are unmet needs among these survivors. METHODS: This article identifies opportunities to address disparities in uterine corpus cancer survival and quality of life, and thereby to increase uterine cancer survivorship among African American women. RESULTS: For cancer survivors, common side effects, lasting for long periods after cancer treatment, include fatigue, loss of strength, lymphedema, and difficulty sleeping. A variety of interventions have been evaluated to address physical and mental health concerns, including exercise and dietary interventions. Considerable information exists about the effectiveness of such interventions for alleviating distress and improving quality of life among cancer survivors, but few studies have focused specifically on African American women with a uterine corpus cancer diagnosis. Research-tested culturally tailored lifestyle interventions are lacking. CONCLUSIONS: There is a need for a better understanding of uterine cancer survivorship among African American women. Additional evaluations of interventions for improving the quality of life and survival of African American uterine cancer survivors are needed.

Reproducing Epidemiologic Research and Ensuring Transparency.

Measures for ensuring that epidemiologic studies are reproducible include making data sets and software available to other researchers so they can verify published findings, conduct alternative analyses of the data, and check for statistical errors or programming errors. Recent developments related to the reproducibility and transparency of epidemiologic studies include the creation of a global platform for sharing data from clinical trials and the anticipated future extension of the global platform to non-clinical trial data. Government agencies and departments such as the US Department of Veterans Affairs Cooperative Studies Program have also enhanced their data repositories and data sharing resources. The Institute of Medicine and the International Committee of Medical Journal Editors released guidance on sharing clinical trial data. The US National Institutes of Health has updated their data-sharing policies. In this issue of the Journal, Shepherd et al. (Am J Epidemiol. 2017;186:387-392) outline a pragmatic approach for reproducible research with sensitive data for studies for which data cannot be shared because of legal or ethical restrictions. Their proposed quasi-reproducible approach facilitates the dissemination of statistical methods and codes to independent researchers. Both reproducibility and quasi-reproducibility can increase transparency for critical evaluation, further dissemination of study methods, and expedite the exchange of ideas among researchers.

Advancing breast cancer survivorship among African-American women.

Advances have occurred in breast cancer survivorship but, for many African-American women, challenges and gaps in relevant information remain. This article identifies opportunities to address disparities in breast cancer survival and quality of life, and thereby to increase breast cancer survivorship among African-American women. For breast cancer survivors, common side effects, lasting for long periods after cancer treatment, include fatigue, loss of strength, difficulty sleeping, and sexual dysfunction. For addressing physical and mental health concerns, a variety of interventions have been evaluated, including exercise and weight training, dietary interventions, yoga and mindfulness-based stress reduction, and support groups or group therapy. Obesity has been associated with breast cancer recurrence and poorer survival. Relative to white survivors, African-American breast cancer survivors are more likely to be obese and less likely to engage in physical activity, although exercise improves overall quality of life and cancer-related fatigue. Considerable information exists about the effectiveness of such interventions for alleviating distress and improving quality of life among breast cancer survivors, but few studies have focused specifically on African-American women with a breast cancer diagnosis. Studies have identified a number of personal factors that are associated with resilience, increased quality of life, and positive adaptation to a breast cancer diagnosis. There is a need for a better understanding of breast cancer survivorship among African-American women. Additional evaluations of interventions for improving the quality of life and survival of African-American breast cancer survivors are desirable.
