RESUMO
Advances in cancer screening and treatment have improved survival after a diagnosis of cancer. As the number of cancer survivors as well as their overall life-expectancy increases, investigations of health-related quality of life (HRQOL) are critical in understanding the factors that promote the optimal experience over the course of survivorship. However, there is a dearth of information on determinants of HRQOL for African American cancer survivors as the vast majority of cohorts have been conducted predominantly among non-Hispanic Whites. In this review, we provide a review of the literature related to HRQOL in cancer survivors including those in African Americans. We then present a summary of published work from the Detroit Research on Cancer Survivors (ROCS) cohort, a population-based cohort of more than 5000 African American cancer survivors. Overall, Detroit ROCS has markedly advanced our understanding of the unique factors contributing to poorer HRQOL among African Americans with cancer. This work and future studies will help inform potential interventions to improve the long-term health of this patient population.
RESUMO
BACKGROUND: Social risks are common among cancer survivors who have the fewest financial resources; however, little is known about how prevalence differs by age at diagnosis, despite younger survivors' relatively low incomes and wealth. METHODS: The authors used data from 3703 participants in the Detroit Research on Cancer Survivors (ROCS) cohort of Black cancer survivors. Participants self-reported several forms of social risks, including food insecurity, housing instability, utility shut-offs, not getting care because of cost or lack of transportation, and feeling unsafe in their home neighborhood. Modified Poisson models were used to estimate prevalence ratios and 95% confidence intervals (CIs) of social risks by age at diagnosis, controlling for demographic, socioeconomic, and cancer-related factors. RESULTS: Overall, 35% of participants reported at least one social risk, and 17% reported two or more risks. Social risk prevalence was highest among young adults aged 20-39 years (47%) followed by those aged 40-54 years (43%), 55-64 years (38%), and 65 years and older (24%; p for trend < .001). Compared with survivors who were aged 65 years and older at diagnosis, adjusted prevalence ratios for any social risk were 1.75 (95% CI, 1.42-2.16) for survivors aged 20-39 years, 1.76 (95% CI, 1.52-2.03) for survivors aged 40-54 years, and 1.41 (95% CI, 1.23-1.60) for survivors aged 55-64 years at diagnosis. Similar associations were observed for individual social risks and experiencing two or more risks. CONCLUSIONS: In this population of Black cancer survivors, social risks were inversely associated with age at diagnosis. Diagnosis in young adulthood and middle age should be considered a risk factor for social risks and should be prioritized in work to reduce the financial effects of cancer on financially vulnerable cancer survivors.

Low circulating vitamin D levels are more prevalent in Black than White individuals. We analyzed the Women's Health Initiative (WHI) calcium plus vitamin D (CaD) randomized clinical trial extended follow-up data to evaluate associations between calcium plus vitamin D supplementation and incident cancer, cardiovascular disease (CVD), and cause-specific mortality endpoints among Black women. Intent-to-treat analysis was performed. Among 3325 Black women in the CaD trial who were randomized into either daily calcium (1000 mg of calcium carbonate) plus vitamin D (400 IU D3) or placebos for an average of 7 years, there were 813 deaths, 588 incident cancers, and 837 CVD events during an average of 15.7 years of follow up (52 230 total person-years). Using Cox's proportional hazards models, we calculated hazard ratios and their confidence intervals for outcomes ascertained during the trial period, posttrial follow-up period and overall periods combined. We found that total mortality, cause-specific mortality, and total cancer incidence were almost identical between CaD and placebo groups. These results suggest that calcium plus vitamin D supplementation does not reduce risks of cancer, CVD, or other major causes of death in Black women overall and, thus, other medical, behavioral or social interventions should be considered to narrow health disparities related to these outcomes. However, other finer endpoints, such as colorectal cancer, warrants further investigation.

BACKGROUND: An association was observed between an inflammation-related risk score (IRRS) and worse overall survival (OS) among a cohort of mostly White women with invasive epithelial ovarian cancer (EOC). Herein, we evaluated the association between the IRRS and OS among Black women with EOC, a population with higher frequencies of pro-inflammatory exposures and worse survival. METHODS: The analysis included 592 Black women diagnosed with EOC from the African American Cancer Epidemiology Study (AACES). Cox proportional hazards models were used to compute hazard ratios (HRs) and 95% confidence intervals (CIs) for the association of the IRRS and OS, adjusting for relevant covariates. Additional inflammation-related exposures, including the energy-adjusted Dietary Inflammatory Index (E-DIITM), were evaluated. RESULTS: A dose-response trend was observed showing higher IRRS was associated with worse OS (per quartile HR: 1.11, 95% CI: 1.01-1.22). Adding the E-DII to the model attenuated the association of IRRS with OS, and increasing E-DII, indicating a more pro-inflammatory diet, was associated with shorter OS (per quartile HR: 1.12, 95% CI: 1.02-1.24). Scoring high on both indices was associated with shorter OS (HR: 1.54, 95% CI: 1.16-2.06). CONCLUSION: Higher levels of inflammation-related exposures were associated with decreased EOC OS among Black women.

BACKGROUND: Coronavirus disease 2019 (COVID-19) has had profound effects on population health to date. African American cancer survivors are particularly vulnerable to developing severe consequences; therefore, understanding the impact of the virus on this patient population is critical. METHODS: The Detroit Research on Cancer Survivors cohort is a unique effort to understand the determinants of poor outcomes in African American cancer survivors. To date, more than 4500 cancer survivors and nearly 950 primary caregivers have been enrolled; participation includes a survey and the collection of biospecimens, medical records, and tumor tissue. Beginning in the spring of 2020, a supplemental survey focusing on the impact of COVID-19 was offered to enrolled participants. The analysis included 890 survivors. RESULTS: Nearly all survivors (>99%) reported changes in their daily activities in an effort to reduce the risk of infection. More than 40% of the survivors reported some disruption in their access to medical care. A substantial proportion of the survivors (>40%) reported feeling anxious, depressed, and/or isolated during the COVID-19 pandemic. Approximately 40% of the patients reported changes in health behaviors shown to negatively affect survivorship outcomes (physical inactivity, smoking, and alcohol use) as a result of the pandemic. CONCLUSIONS: The influence of the COVID-19 pandemic on African American cancer survivors is substantial: it has affected both their physical and mental health. Coupled with changes in health behaviors, these factors will likely affect outcomes in this high-risk patient population, and this makes further study and interventions necessary to mitigate the long-term impact of the pandemic on cancer outcomes.

BACKGROUND: Social needs may affect cancer survivors' health-related quality of life (HRQOL) above and beyond sociodemographic and cancer-related factors. The purpose of this study was to estimate associations between social needs and HRQOL. METHODS: Results included data from 1754 participants in the Detroit Research on Cancer Survivors cohort, a population-based study of African American survivors of breast, colorectal, lung, and prostate cancer. Social needs included items related to food insecurity, utility shutoffs, housing instability, not getting health care because of cost or a lack of transportation, and perceptions of neighborhood safety. HRQOL was measured with the validated Functional Assessment of Cancer Therapy-General (FACT-G). Linear regression models controlled for demographic, socioeconomic, and cancer-related factors. RESULTS: More than one-third of the survivors (36.3%) reported social needs including 17.1% of survivors reported 2 or more. The prevalence of social needs ranged from 14.8% for food insecurity to 8.9% for utility shutoffs. FACT-G score differences associated with social needs were -12.2 (95% confidence interval [CI] to -15.2 to -9.3) for not getting care because of a lack of transportation, -11.3 (95% CI, -14.2 to -8.4) for housing instability, -10.1 (95% CI, -12.7 to -7.4) for food insecurity, -9.8 (95% CI, -12.7 to -6.9) for feeling unsafe in the neighborhood, -8.6 (95% CI, -11.7 to -5.4) for utility shutoffs, and -6.7 (95% CI, -9.2 to -4.1) for not getting care because of cost. CONCLUSIONS: Social needs were common in this cohort of African American cancer survivors and were associated with clinically significant differences in HRQOL. Clinical oncology care and survivorship care planning may present opportunities to screen for and address social needs to mitigate their impact on survivors' HRQOL.

BACKGROUND: Extant evidence links neighborhood walkability with obesity-related health in the general population. This association likely exists in cancer survivors, but research is limited. Furthermore, a disproportionate obesity burden in African American cancer survivors warrants subgroup-specific analyses. METHODS: This study analyzed data from 2089 African American cancer survivors participating in the Detroit Research on Cancer Survivors (ROCS) cohort. On the basis of built environment data summarized within 1-km radial buffers around census block centroids, a multidimensional neighborhood walkability index (NWI) was constructed. Survivors' residential addresses at Detroit ROCS enrollment were geocoded, and addresses were linked to NWI scores via the census block of residence. At study enrollment, survivors reported height and weight; these data were used to calculate their body mass index (BMI). Associations between NWI quartiles and BMI overall and by cancer type, biological sex, and physical activity engagement were evaluated. RESULTS: BMI was found to be inversely associated with increasing NWI quartile (P for trend < .01). This inverse relationship was observed in men (P for trend < .01) and in survivors reporting any regular physical activity (P for trend < .01). CONCLUSIONS: This study's findings suggest that among African American cancer survivors, higher neighborhood walkability is associated with lower BMI. As health care systems in the United States increasingly consider the role of the neighborhood environment in their patients' health, these findings provide additional evidence supporting health systems' incorporation of neighborhood walkability as an obesity-related health indicator for this cancer survivor subgroup and potentially for cancer survivors from other vulnerable populations.

BACKGROUND: Cardiometabolic abnormalities are a leading cause of death among women, including women with cancer. METHODS: This study examined the association between prediagnosis cardiovascular health and total and cause-specific mortality among 12,076 postmenopausal women who developed local- or regional-stage invasive cancer in the Women's Health Initiative (WHI). Cardiovascular risk factors included waist circumference, hypertension, high cholesterol, and type 2 diabetes. Obesity-related cancers included breast cancer, colorectal cancer, endometrial cancer, kidney cancer, pancreatic cancer, ovarian cancer, stomach cancer, liver cancer, and non-Hodgkin lymphoma. Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) adjusted for important predictors of survival. RESULTS: After a median follow-up of 10.0 years from the date of the cancer diagnosis, there were 3607 total deaths, with 1546 (43%) due to cancer. Most participants (62.9%) had 1 or 2 cardiometabolic risk factors, and 8.1% had 3 or 4. In adjusted models, women with 3 to 4 risk factors (vs none) had a higher risk of all-cause mortality (HR, 1.99; 95% CI, 1.73-2.30), death due to cardiovascular disease (CVD) (HR, 4.01; 95% CI, 2.88-5.57), cancer-specific mortality (HR, 1.37; 95% CI, 1.1-1.72), and other-cause mortality (HR, 2.14; 95% CI, 1.70-2.69). A higher waist circumference was associated with greater all-cause mortality (HR, 1.17; 95% CI, 1.06-1.30) and cancer-specific mortality (HR, 1.22; 95% CI, 1.04-1.42). CONCLUSIONS: Among postmenopausal women diagnosed with cancer in the WHI, cardiometabolic risk factors before the cancer diagnosis were associated with greater all-cause, CVD, cancer-specific, and other-cause mortality. These results raise hypotheses regarding potential clinical intervention strategies targeting cardiometabolic abnormalities that require future prospective studies for confirmation. LAY SUMMARY: This study uses information from the Women's Health Initiative (WHI) to find out whether cardiac risk factors are related to a greater risk of dying among older women with cancer. The WHI is the largest study of medical problems faced by older women in this country. The results show that women who have 3 or 4 risk factors are more likely to die of any cause, heart disease, or cancer in comparison with women with no risk factors. It is concluded that interventions to help to lower the burden of cardiac risk factors can have an important impact on survivorship among women with cancer.

BACKGROUND: The benefit of regular exercise in improving cancer outcomes is well established. The American Cancer Society (ACS) released a recommendation that cancer survivors should engage in at least 150 minutes of moderate to vigorous physical activity (PA) per week; however, few report meeting this recommendation. This study examined the patterns and correlates of meeting ACS PA recommendations in the Detroit Research on Cancer Survivors (ROCS) cohort of African American cancer survivors. METHODS: Detroit ROCS participants completed baseline and yearly follow-up surveys to update their health and health behaviors, including PA. This study examined participation in PA by select characteristics and reported health-related quality of life (HRQOL) as measured with the Functional Assessment of Cancer Therapy and Patient-Reported Outcomes Measurement Information System instruments. RESULTS: Among the first 1500 ROCS participants, 60% reported participating in regular PA, with 24% reporting ≥150 min/wk. Although there were no differences by sex, prostate cancer survivors were the most likely to report participating in regular PA, whereas lung cancer survivors were the least likely (P = .022). Survivors who reported participating in regular PA reported higher HRQOL (P < .001) and lower depression (P = .040). CONCLUSIONS: Just 24% of African American cancer survivors reported meeting the ACS guidelines for PA at the baseline, but it was encouraging to see increases in activity over time. Because of the established benefits of regular exercise observed in this study and others, identifying and reducing barriers to regular PA among African American cancer survivors are critical for improving outcomes and minimizing disparities.

BACKGROUND: African American women (AAW) die more frequently from estrogen receptor (ER) positive breast cancer than European American women (EAW). We investigated the relationship between race, percent ER staining, treatment, and clinical outcomes. METHODS: Percent ER staining (weakly ER+: 1-10%, moderately ER+: 11-50%, strongly ER+: > 50%) was abstracted from pathology reports for 1573 women with ER+/HER2- invasive breast cancer treated at a single cancer center in Detroit, MI from 2010 to 2017. Clinical outcomes and tumor characteristics were obtained from the Metropolitan Detroit Cancer Surveillance System. Associations of ER levels with demographic and clinical characteristics were evaluated using logistic regression. Overall and breast cancer-specific (BCS) survival were evaluated using Cox proportional hazards models. RESULTS: AAW were more likely to have tumors with lower ER staining levels than EAW (weakly ER+: Odds ratio (OR) 2.19, p = 0.019; moderately ER+: OR 2.80, p = 0.005). Women with weakly compared to strongly ER+ tumors were less likely to receive endocrine therapy (ET) regardless of race (OR 0.79, p < 0.001). Mortality was predicted by both AA race (Overall hazard ratio (HR) = 1.72, p < 0.001; BCS HR 1.45, p = 0.08) and low (1-50%) ER (Overall HR 1.57, p = 0.083; BCS HR 2.11, p = 0.017) adjusting for clinic-pathologic characteristics. ET was associated with improved BCS survival in all women (1-50%: HR 0.11, p < 0.001; > 50%: HR 0.24, p < 0.001). CONCLUSION: The biology of ER+/HER2- tumors varies by race, although this does not appear to account for racial differences in survival. Although ET substantially reduces mortality among women with weakly ER+ tumors, these women are less likely to be treated with ET and have poorer outcomes.

PURPOSE: We explored how lifetime comorbidities and treatment-related cancer symptoms were associated with quality of life (QOL) in rural cancer survivors. METHODS: Survivors (n = 125) who were rural Illinois residents aged 18+ years old were recruited from January 2017 to September 2018. We conducted 4 multivariable regressions with QOL domains as outcomes (social well-being, functional well-being, mental health-MHQOL, physical health-PHQOL); the number of physical and psychological comorbidities (e.g., arthritis, high blood pressure, stroke) and treatment-related cancer symptoms (e.g., worrying, feeling sad, lack of appetite, lack of energy) as predictors; and, cancer-related and demographic factors related to these variables as covariates. RESULTS: The number of comorbidities and number of treatment-related symptoms were inversely associated with functional well-being (Std ß = - 0.36, p < 0.0001 and - 0.18, p = 0.03), and MHQOL (Std ß = - 0.30, p = 0.001 and Std ß = - 0.25, p = 0.004). Comorbidities were associated inversely with social well-being (Std ß = - 0.27, p = .003). Comorbidities and treatment-related symptoms were not associated with PHQOL (p = 0.20-0.24). Sensitivity analyses suggested that psychological comorbidities, treatment-related psychological symptoms, and physical comorbidities were associated with social well-being, functional well-being, and MHQOL. CONCLUSIONS: Our study highlights the utility of risk-based survivorship care plans to address the negative, additive impact of comorbidities and the treatment-related symptoms to improve the health-related QOL among rural survivors. Future research should assess how contextual factors (e.g., geographic distance to oncologists and other providers) should be incorporated in survivorship care planning and implementation for rural survivors.

Risk factors can drive socioeconomic inequalities in cardiovascular disease (CVD) through differential exposure and differential vulnerability. In this paper, we show how econometric decomposition directly enables simultaneous, policy-oriented assessment of these 2 mechanisms. We specifically estimate contributions of neighborhood environment and proximal risk factors to socioeconomic inequality in CVD incidence via these mechanisms. We followed 5,608 participants in the Multi-Ethnic Study of Atherosclerosis (2000-2012) to their first CVD event (median length of follow-up, 12.2 years). We used a summary measure of baseline socioeconomic position (SEP). Covariates included baseline demographics, neighborhood characteristics, and psychosocial, behavioral, and biomedical risk factors. Using Poisson models, we decomposed the difference (inequality) in incidence rates between low- and high-SEP groups into contributions of 1) differences in covariate means (differential exposure) and 2) differences in CVD risk associated with covariates (differential vulnerability). Notwithstanding large uncertainty in neighborhood estimates, our analysis suggested that differential exposure to poorer neighborhood socioeconomic conditions, adverse social environment, diabetes, and hypertension accounted for most of the inequality. Psychosocial and behavioral contributions were negligible. Further, neighborhood SEP, female sex, and white race were more strongly associated with CVD among low-SEP (vs. high-SEP) participants. These differentials in vulnerability also accounted for nontrivial portions of the inequality and could have important implications for intervention.

BACKGROUND: Few studies have examined the relationship between cardiometabolic risk factors linked to metabolic syndrome and mortality among women with breast cancer. METHODS: We used the Women's Health Initiative to evaluate the relationship between cardiometabolic risk factors, including waist circumference (WC), blood pressure, cholesterol level, and presence of type 2 diabetes, and their relation with death from breast cancer, cardiovascular disease (CVD), and other causes among 8641 women with local or regional stage invasive breast cancer. Cox proportional hazards models were used to estimate hazard ratios, and 95% confidence intervals, adjusted for important predictors of survival. RESULTS: After a median of 11.3 years, there were 2181 total deaths, 619 (28.4%) of which were due to breast cancer. Most participants (55.7%) had at least 2 cardiometabolic risk factors, and 4.9% had 3 or 4. Having a larger number of risk factors was associated with higher risk of CVD and other-cause mortality (P trend < .001 for both), but not with breast cancer mortality (P trend = .86). Increased WC was associated with a higher risk of CVD (hazard ratio [HR], 1.28; 95% confidence interval [CI], 1.05-1.57) and other-cause mortality (HR, 1.32; 95% CI, 1.16-1.49) and only with a small and nonsignificant higher risk of breast cancer mortality (HR, 1.19; 95% CI, 0.93-1.52). The results did not differ in analyses stratified by race, hormone receptor status, or after an analysis of cases diagnosed within 5 years after baseline. CONCLUSIONS: Among women with early stage breast cancer, cardiometabolic risk factors are significantly associated with cardiovascular and other-cause mortality, but not breast cancer mortality.

PURPOSE: In 2007, the World Cancer Research Fund (WCRF) and American Institute for Cancer Research (AICR) published eight recommendations regarding body weight, physical activity, and dietary behaviors aimed at reducing cancer incidence worldwide. In this paper, we assess whether meeting the WCRF/AICR recommendations is associated with lower colorectal cancer (CRC) incidence; evaluate whether particular recommendations are most strongly associated with lower CRC incidence; and assess whether associations differ by sex. METHODS: We operationalized six of the recommendations (related to body weight, physical activity, energy density, plant foods, red and processed meat, and alcohol) and examined their association with CRC incidence over 7.6 years of follow-up in the prospective VITamins And Lifestyle Study cohort. Participants included 66,920 adults aged 50-76 years at baseline (2000-2002) with no history of CRC and with complete data for the recommendations evaluated. Incident colorectal cancers (n = 546) were tracked through 2009. RESULTS: Compared with meeting no recommendations, meeting 1-3 recommendations was associated with 34-45 % lower CRC incidence, and meeting 4-6 was associated with 58 % lower incidence (95 % CI 34 %, 74 %) in fully adjusted analyses. The recommendations most strongly associated with lower CRC risk for women were related to body fatness and red and processed meat, while for men these were alcohol intake and red and processed meat. Differences by sex were statistically significant (p < 0.05) for the recommendations related to body weight and to alcohol. CONCLUSIONS: Meeting the WCRF/AICR recommendations, particularly those related to alcohol, body weight, and red and processed meat, could substantially reduce CRC incidence; however, associations differ by sex.

OBJECTIVE: To examine whether total physical activity or activity patterns are associated with metabolic syndrome and its components. METHODS: Participants include 1994 controls from a case-control study of non-fatal myocardial infarction in Costa Rica (1994-2004). Physical activity was assessed via self-administered questionnaire and patterns were identified using principal components analysis. Metabolic syndrome was assessed via blood samples and anthropometry measurements from in-home study visits. Prevalence ratios (PRs) and 95% confidence intervals (CIs) were calculated using log binomial regression. Adjusted least squares means of metabolic syndrome components were calculated by quintile of total activity and pattern scores. RESULTS: Four activity patterns were identified: rest/sleep, agricultural, light indoor activity, and manual labor. Total activity was not associated with metabolic syndrome. Metabolic syndrome prevalence was 20% lower in participants with the highest scores on the agricultural job pattern compared to those with the lowest (PR: 0.80, 95% CI: 0.68-0.94). Higher total activity was associated with lower triglycerides and lower HDL cholesterol. Higher scores on each pattern were inversely associated with metabolic syndrome components, particularly waist circumference and fasting blood glucose. CONCLUSIONS: Patterns or types of physical activity may be more strongly associated with metabolic syndrome and its components than total activity levels.

PURPOSE: In 2007, the World Cancer Research Fund (WCRF) and American Institute for Cancer Research (AICR) released eight recommendations related to body fatness, physical activity, and diet aimed at preventing the most common cancers worldwide. The purpose of this paper is to estimate the association between meeting these recommendations and cancer-specific mortality. METHODS: We operationalized six recommendations (related to body fatness; physical activity; and consumption of foods that promote weight gain, plant foods, red and processed meat, and alcohol) and examined their association with cancer-specific mortality over 7.7 years of follow-up in the Vitamins and Lifestyle (VITAL) Study cohort. Participants included 57,841 men and women ages 50-76 in 2000-2002 who had not been diagnosed with cancer prior to baseline. Cancer-specific deaths (n = 1,595) were tracked through the Washington State death file. RESULTS: Meeting the recommendations related to plant foods and foods that promote weight gain were most strongly associated with lower cancer-specific mortality [hazard ratio (HR) 0.82, 95 % confidence interval (CI) 0.67, 1.00 and HR 0.82, 95 % CI 0.70, 0.96, respectively]. Cancer-specific mortality was 61 % lower in respondents who met at least five recommendations compared to those who met none (HR 0.39, 95 % CI 0.24, 0.62). Cancer-specific mortality was 10 % lower on an average with each additional recommendation met (per-recommendation HR 0.90, 95 % CI 0.85, 0.94; p trend < 0.001). This association did not differ by sex or age but was stronger in non-smokers (HR 0.84, 95 % CI 0.76, 0.92) than in smokers (HR 0.93, 95 % CI 0.87, 0.98; p interaction = 0.086). CONCLUSION: Adherence to the WCRF/AICR cancer prevention recommendations developed to reduce incidence of common cancers could substantially reduce cancer-specific mortality in older adults.

Addressing social risks in cancer prevention and control presents a new opportunity for accelerating cancer health equity. As members of the American Society of Preventive Oncology (ASPO) Cancer Health Disparities Special Interest Group, we describe the current state of science on social risks in oncology research and practice. To reduce and eliminate the unjust burden of cancer, we also provide recommendations for multilevel research examining social risks as contributors to inequities and the development of social risks-focused interventions. Suggestions for research and practice are provided within levels of the socio-ecological model, including the interpersonal, organizational, community, and policy levels.

PURPOSE: Eating frequency is a modifiable aspect of dietary behavior that may affect risk of colorectal cancer (CRC). Although most previous case-control studies indicate a positive association, two prospective studies suggest an inverse association between eating frequency and CRC risk, with evidence of effect modification by diet composition. We examined the association between eating frequency and CRC in a large, prospective cohort study, and explored whether this relationship was modified by sex, coffee consumption, or dietary glycemic load. METHODS: Between 2000 and 2002, 67,912 western Washington residents aged 50-76 reported average daily meal and snack frequency using a mailed questionnaire as part of the vitamins and lifestyle study. Participants were followed for CRC through linkage with SEER through 2008, over which time 409 CRC cases developed. Hazard Ratios and 95 % Confidence Intervals were obtained using Cox regression. RESULTS: In age- and sex-adjusted models higher (5+ times/d) vs. lower (1-2 times/d) eating frequency was associated with a HR of 0.62 (95 % CI 0.43-0.88, Ptrend = 0.001). However, following further adjustment for BMI, race/ethnicity, alcohol, and other known CRC risk factors, the relationship was no longer statistically significant (HR: 0.76; 95 % CI 0.51, 1.14). No effect modification was observed by sex (Pinteraction = 0.45), coffee consumption (Pinteraction = 0.44), or dietary glycemic load (Pinteraction = 0.90). In subgroup analyses by tumor site, higher vs. lower eating frequency was associated with lower risk for colon (HR 0.65 95 % CI 0.39-1.07, Ptrend = 0.04), but not rectal cancers (HR = 1.08 95 % CI 0.54-2.18, Ptrend = 0.94). CONCLUSION: The weak inverse association observed between eating frequency and CRC is consistent with findings from other prospective studies. Modification of this relationship by diet quality and participant characteristics should be considered in the future studies.

OBJECTIVES: This study describes the communication-related concerns of oncology providers in addressing financial issues with patients. METHODS: We conducted semi-structured interviews with 17 providers (9 clinicians, 5 social workers/navigators, 3 attorneys) who addressed financial concerns with cancer patients and analyzed resulting transcripts using qualitative thematic analysis. Interview topics included cost-related concerns of patients, resources providers used, and unmet needs related to addressing financial issues. Here we present codes and content related to a cross-cutting cost communication, stratified by provider discipline. RESULTS: Communication-related issues varied by provider type. Clinicians identified lack of information, lack of time, and the need for additional support as major barriers to effective cost discussions. Social workers/navigators expressed the importance of establishing a relationship before discussing costs and on the need to revisit cost concerns over time to meet patients' changing needs. The attorneys endorsed the need for more and earlier cost communication to prevent financial hardship. CONCLUSION: Communication concerns and strategies were central to providers' experiences of addressing cancer patient cost concerns. PRACTICE IMPLICATIONS: Understanding the experiences of diverse oncology providers can inform the development and implementation of interventions to prevent and mitigate financial hardship in people with cancer.

PURPOSE: As health care systems seek to screen for and address housing instability in patient populations, robust evidence linking unstable housing to patient-reported outcomes is needed. Housing instability may increase psychological distress in cancer survivors, potentially more so among African American cancer survivors who are also likely to experience disproportionate burden of housing instability. The purpose of this analysis was to estimate associations between housing instability and psychological distress in African Americans diagnosed with cancer. METHODS: We included survey responses from 2875 African American cancer survivors in the Detroit Research on Cancer Survivors (ROCS) study. We examined how housing instability at enrollment, using an item adapted from the Health Leads Screening Toolkit, related to psychological distress at enrollment, using Patient Reported Outcomes Measurement System (PROMIS) 4-item anxiety and depression short forms. Linear regression models adjusted for sociodemographic factors were used to estimate associations overall and stratified by stage at diagnosis. RESULTS: Approximately 12% of participants reported being unstably housed. Housing instability was associated with significant differences in PROMIS scores for both anxiety (difference: 6.79; 95% CI: 5.57-8.01) and depression (difference: 6.16; 95% CI: 4.99-7.34). We did not find meaningful differences stratifying by disease stage. CONCLUSION: Housing instability was experienced by over a tenth of this cohort of African American cancer survivors and was related to statistically and clinically meaningful differences in psychological distress even following adjustment for sociodemographics. IMPLICATIONS FOR CANCER SURVIVORS: These findings provide evidence supporting screening of housing instability in cancer survivors, especially those from medically underserved populations.
