Chondroitin Sulfate for Osteoarthritis – Is There a Risk for Cancer: an Analysis of Osteoarthritis Initiative Data

The aim of this study was to evaluate the association between chondroitin sulfate (CS) use and incidence of self-reported cancer during 6-year follow up in the publicly available Osteoarthritis Initiative (OAI) cohort participants.
 Materials and Methods: The current study included analysis of 6-year longitudinal data obtained from the OAI progression (n= 1390) and incidence (n = 3284) subcohorts that are publicly available at https://nda.nih.gov/oai/. The inclusion criteria for OAI were the following: age between 45 and 79 years for both subcohorts, symptomatic tibiofemoral knee osteoarthritis (OA) for the progression subcohort, and the presence of established or putative risk factors for incident knee OA for the incidence subcohort. The OAI participants were recruited and enrolled between February 2004 and May 2006 at four recruitment centres in the United States. This study received ethical approval from each recruitment centre. All participants provided written informed consent. To reduce the risk of bias, only participants who did not take CS at baseline were included in the analysis (a “new-user” design).
 Results: 570 (18%) new users of CS and 2597 (82%) CS non-users were compared. In the CS user group, 294 (51.6%) participants received CS for more than one year, 291 (33.5%) for more than 2 years, 123 (21.6%) for more than 3 years, and 60 (10.5%) for more than 4 years. None of the participants received CS for more than 5 years. CS users and non-users were of the same age, had similar male/female ratio, and similar body mass index. In the non-user group, there were more African-American participants and there were more current smokers. 160 (6.2%) and 37 (6.5%) cases of incident self-reported cancer in the non-users and user groups were identified. There was no association between the use of CS and incident self-reported cancer in the non-adjusted analyses. The adjustments for age, race and smoking status did not change the results.
 Conclusion: The results of the current study did not show an association between CS use and self-reported cancers. Considering the complex function of CS in the development and progression of malignant tumors, there is a need for further epidemiological studies evaluating CS effects on specific types of cancers and in different genetic backgrounds.

Patterns of Cancer-Related Healthcare Access across Pennsylvania: Analysis of Novel Census Tract-Level Indicators of Persistent Poverty.

Persistent poverty census tracts have had ≥20% of the population living below the federal poverty line for 30+ years. We assessed the relationship between persistent poverty and cancer-related healthcare access across census tracts in Pennsylvania. We gathered publicly available census tract-level data on persistent poverty, rurality, and sociodemographic variables, as well as potential access to healthcare (i.e., prevalence of health insurance, last-year check-up), realized access to healthcare (i.e., prevalence of screening for cervical, breast, and colorectal cancers), and self-reported cancer diagnosis. We used multivariable spatial regression models to assess the relationships between persistent poverty and each healthcare access indicator. Among Pennsylvania's census tracts, 2,789 (89.8%) were classified as non-persistent poverty, and 316 (10.2%) were classified as persistent poverty (113 did not have valid data on persistent poverty). Persistent poverty tracts had lower prevalence of health insurance [estimate = -1.70, standard error (SE) = 0.10], screening for cervical cancer (estimate = -4.00, SE = 0.17) and colorectal cancer (estimate = -3.13, SE = 0.20), and cancer diagnosis (estimate = -0.34, SE = 0.05), compared with non-persistent poverty tracts (all P < 0.001). However, persistent poverty tracts had higher prevalence of last-year check-up (estimate = 0.22, SE = 0.08) and screening for breast cancer (estimate = 0.56, SE = 0.15; both P < 0.01). Relationships between persistent poverty and cancer-related healthcare access outcomes differed in direction and magnitude. Health promotion interventions should leverage data at fine-grained geographic units (e.g., census tracts) to motivate focus on communities or outcomes. Future studies should extend these analyses to other states and outcomes to inform public health research and interventions to reduce geographic disparities.

Association between cytomegalovirus seropositivity and all-cause mortality: An original cohort study.

To examine the association between cytomegalovirus (CMV) seropositivity and all-cause mortality in a nationwide cohort of US adults. We obtained data from the National Health and Nutrition Examination Survey III (1988-1994), including 16,547 participants aged 18-90 years old with CMV serology assessments. Mortality status was ascertained until December 2019 using the National Death Index linkage data. The Cox proportional hazard model was applied to estimate the association between CMV seropositivity and mortality. During a median follow-up of 26.3 years, 6,930 deaths were recorded. CMV seropositivity was associated with a higher hazard of all-cause mortality after adjusting for attained age, sex, and ethnicity (HR: 1.22, 95% CI: 1.10, 1.36, p < 0.001). The magnitude of the association attenuated slightly after adjusting further for body mass index, family income, smoking status, diabetes, and self-reported cancer history (HR = 1.11, 95% CI: 1.00, 1.23, p = 0.04). While the association was observed for both men and women, it was only statistically significant among non-Hispanic white people (HR: 1.16, 95% CI: 1.06, 1.26, p = 0.001) but not among other ethnic populations. CMV seropositivity might be an independent risk factor for all-cause mortality among US adults. If the findings are validated in an independent population, further research is needed to unveil the biological mechanisms driving the increased mortality with CMV seropositivity.

Intersectional analysis of inequalities in self-reported breast cancer screening attendance using supervised machine learning and PROGRESS-Plus framework.

Breast cancer is a critical public health concern in Spain, and organized screening programs have been in place since the 1990s to reduce its incidence. However, despite the bi-annual invitation for breast cancer screening (BCS) for women aged 45-69, significant attendance inequalities persist among different population groups. This study employs a quantitative intersectional perspective to identify intersectional positions at risk of not undergoing breast cancer screening in Spain. Women were selected from the 2020 European Health Interview Survey in Spain, which surveyed the adult population (> 15 years old) living in private households (N = 22,072; 59% response rate). Inequality indicators based on the PROGRESS-Plus framework were used to disentangle existing social intersections. To identify intersectional groups, decision tree models, including classification and regression trees (CARTs), chi-squared automatic interaction detector (CHAID), conditional inference rees (CITs), and C5.0, along with an ensemble algorithm, extreme gradient boosting (XGBoost), were applied. XGBoost (AUC 78.8%) identified regional differences (Autonomous Community) as the most important factor for classifying BCS attendance, followed by education, age, and marital status. The C5.0 model (balanced accuracy 81.1%) highlighted that the relative importance of individual characteristics, such as education, marital status, or age, for attendance differs based on women's place of residence and their degree of interaction. The highest risk of not attending BCS was observed among illiterate older women in lower social classes who were born in Spain, were residing in Asturias, Cantabria, Basque Country, Castile and León, Extremadura, Galicia, Madrid, Murcia, La Rioja, or Valencian Community, and were married, divorced, or widowed. Subsequently, the risk of not attending BCS extends to three other groups of women: women living in Ceuta and Melilla; single or legally separated women living in the rest of Spain; and women not born in Spain who were married, divorced, or widowed and not residing in Ceuta or Melilla. The combined use of decision trees and ensemble algorithms can be a valuable tool in identifying intersectional positions at a higher risk of not utilizing public resources and, thus, can aid substantially in developing targeted interventions to increase BCS attendance.

Impact of smoking status on health-related quality of life (HRQoL) in cancer survivors.

The Health-Related Quality of Life (HRQoL) often declines among cancer survivors due to many factors. Some cancer patients who smoke before the cancer diagnosis continue this harmful habit, potentially contributing to a more significant decline in their HRQoL. Therefore, this study investigates the association between smoking status and HRQoL in cancer survivors. We conducted a cross-sectional study utilizing self-reported cancer history from 39,578 participants of the Behavioral Risk Factor Surveillance System (BRFSS) database, leveraging 2016 and 2020 year questionaries. A multidimensional composite outcome was created to assess HRQoL, integrating four distinct dimensions - general health, mental health, physical health, and activity limitations. After accounting for the complex survey design, logistic regression models were used to analyze the association between smoking status and poor HRQoL, adjusting for demographic, socioeconomic, and health-related confounders. Our study found that, after adjusting for potential confounders, current smokers exhibited a significantly poorer HRQoL than never smokers (OR 1.65, 95%CI 1.40-1.93). Furthermore, former smokers showed a poorer HRQoL than never smokers; however, this association was not as strong as current smokers (OR 1.22, 95%CI 1.09-1.38). Our findings highlight the adverse association of smoking with poor HRQoL in cancer survivors, underscoring the importance of healthcare professionals prioritizing smoking cessation and providing tailored interventions to support this goal.

Spatial distribution and characteristics of women reporting cervical cancer screening in Malawi: An analysis of the 2020 to 2021 Malawi Population-based HIV Impact Assessment survey data.

Malawi has one of the highest incidence and mortality rates of cervical cancer in the world. Despite a national strategic plan and the roll-out of VIA and screen-and-treat services, cervical cancer screening coverage in Malawi remains far below the national target.Using a nationally representative sample of women enumerated in the Malawi Population-based Impact Assessment (MPHIA) survey we estimated the prevalence and spatial distribution of self-reported cervical cancer screening as a proxy for uptake in Malawi. MPHIA was a nationally representative household survey in Malawi, targeting adults aged 15 and above, that employed a cross-sectional, two-stage, cluster design. The primary aim of MPHIA was to assess the regional prevalence of viral load suppression and the progress towards achieving the UNAIDS 95-95-95 goals among adults aged 15 and above. The survey was carried out between January 2020 and April 2021. Prevalence of self-reported cervical cancer screening by different characteristics was estimated accounting for the survey design using the Taylor series approach. We used univariable and multivariable logistic regression approaches to examine associations between the prevalence of cervical cancer screening and demographic characteristics. A total of 13,067 adult (15 years and older) female individuals were surveyed during the MPHIA 2020 to 2021 survey, corresponding to a weighted total of 5,604,578. The prevalence of self-reported cervical cancer screening was 16.5% (95% CI 15.5-18.0%), with women living with HIV having a higher prevalence of 37.8% (95% CI 34.8-40.9) compared to 14.0% (95% CI 13.0-15.0) in HIV negative women. The highest prevalence of screening was reported in the Southwest zone (SWZ) (24.1%, 95% CI 21.3-26.9) and in major cities of Blantyre (25.9%, 95% CI 22.9-29.0), and Lilongwe (19.6%, 95% CI 18.0-21.3). Higher self-reported screening was observed in women who resided in urban regions ((22.7%; 95% CI 21.4-24.0) versus women who resided in rural areas (15.2%; 95% CI 14.0-16.8). Cervical cancer screening was strongly associated with being HIV positive (aOR 2.83; 95% CI 2.29-3.50), ever having been pregnant (aOR 1.93; 95% CI 1.19-3.14), attaining higher education level than secondary education (aOR 2.74; 95% CI 1.67-4.52) and being in the highest wealth quintile (aOR 2.86; 95% CI 2.01-4.08). The coverage of cervical cancer screening in Malawi remains low and unequal by region and wealth/education class. Current screening efforts are largely being focussed on women accessing HIV services. There is need for deliberate interventions to upscale cervical cancer screening in both HIV negative women and women living with HIV.

Abstract A139: Examining the association of cardiovascular health attainment with cancer screening adherence in community-dwelling Black women

Abstract Purpose of the study Cancer and cardiovascular disease are leading causes of death in the United States and share modifiable risk factors. Increasing ideal cardiovascular health indicated by the American Heart Association’s Life’s Simple 7 metrics (LS7: blood pressure, glucose, cholesterol, body mass index, physical activity, and smoking) and cancer screening adherence are both associated with reducing cancer-related mortality. However, there have been no studies to identify associations between LS7 and cancer screening adherence. It is well documented that people adopting positive health behaviors like physical activity and healthy eating have higher cancer screening adherence. Unfortunately, disparities by race exist in both engagement in health behaviors (key metrics of LS7) and cancer screening. Cancer screening disparities between Black and White women have narrowed over time; however, there are disparities in LS7 attainment by race. Here, we examined the association of LS7 attainment with screen detectable cancer (breast, cervical, and colorectal) adherence in Black women. Methods The Partnering in Negating Statistics (P.I.N.S.) for Black Women Initiative promotes health and wellness among Black women. Its community wellness events provide health education, screenings (e.g., breast, cervical, and cardiovascular health), and research participation opportunities. At P.I.N.S. events, LS7 metrics (score range 0-14) and self-reported cancer screening history were collected. The associations of LS7 with cancer screening adherence were examined using multinomial logistic regression adjusting for age, income, and education. Results In 2021 and 2022, 296 Black women participated in cardiovascular health screenings. They had a mean age of 50.1 years (SD 14.1); 66% employed; 88% insured; 69% with educational attainment ≥ college. The 166 participants with complete LS7 data had intermediate cardiovascular health with a median score of 8 [7-10]. In age adjusted models, a 1-unit increase in LS7 attainment was associated with a 45% higher odds of breast cancer screening adherence (OR 1.45, 95%CI: 1.03, 2.05; n=93), which was similar with full adjustment (OR 1.50, 95% CI: 0.95, 2.39; n=91). There was no association of LS7 attainment with cervical (OR 1.09, p=0.40; n=124) or colorectal cancer (OR 1.05, p=0.70; n=84) screening adherence. Conclusions In community-dwelling Black women, increasing LS7 attainment may increase odds of breast cancer screening adherence. Research with a larger sample is needed. Citation Format: Timiya S.

Associations between experience of stressful life events and cancer prevalence in China: results from the China Kadoorie Biobank study

BackgroundStudies examining the relationships of stressful life events and cancer yielded inconsistent findings, while relevant evidence in mainland China is scarce. The current study sought to determine whether experience of stressful life events was associated with cancer prevalence in Chinese population.MethodsWe used cross-sectional data from the China Kadoorie Biobank study which that recruited 0.5 million Chinese adults aged 30 to 79 from 2004 to 2008. Logistic regression models were used to estimate adjusted odds ratios (ORs) with 95% confidence intervals (CIs) for cancer associated with stressful life events reported at baseline.ResultsAmong the 461,696 participants included in this analysis, 2,122 (0.46%) had self-reported cancer with the mean (SD) age was 57.12 (9.71) years. Compared to those without any stressful life event, participants who experienced 1 and 2 or more events had significantly higher odds of cancer, with the ORs of 1.80 (95% CI: 1.58–2.05) and 3.05 (2.18–4.28). For categories of work-, family-, and personal-related events, the OR of cancer was 1.48 (1.07–2.05), 2.06 (1.80–2.35), and 1.65 (1.17–2.33), respectively. Regarding the specific stressful life events, loss of income/living on debt, major conflict within family, death/major illness of other close family member, and major injury/traffic accident were significantly associated with increased odds of cancer, with the ORs of 2.64 (1.81–3.86), 1.73 (1.20–2.50), 2.36 (2.05–2.72), and 2.11 (1.43–3.13).ConclusionOur findings suggested that experiences of cumulative and specific stressful life events were significantly associated with increased cancer prevalence in Chinese population.

Treatment-seeking behaviour among 15–49-year-olds with self-reported heart disease, cancer, chronic respiratory disease, and diabetes: a national cross-sectional study in India

BackgroundEighty per cent of India´s non-communicable disease (NCD) mortality is due to four conditions: heart disease, cancer, chronic respiratory disease, and diabetes, which are primarily cause-amenable through treatment. Based on Andersen’s behavioural model of health services use, the current study aimed to identify the predisposing, enabling, and need factors associated with treatment-seeking status among people self-reporting the four main NCDs in India.MethodsCross-sectional study using secondary data. Usual residents aged 15–49 who self-reported cancer (n = 1 056), chronic respiratory disease (n = 10 534), diabetes (n = 13 501), and/or heart disease (n = 5 861) during the fifth National Family and Health Survey (NFHS-5), 2019–21, were included. Treatment-seeking status was modelled separately for each disease using survey-adjusted multivariable logistic regression.Results3.9% of India´s 15–49-year-old population self-reported ≥ 1 of the four main NCDs (0.1% cancer, 1.4% chronic respiratory disease, 2% diabetes, 0.8% heart disease). The percentage that had sought treatment for their condition(s) was 82%, 68%, 76%, and 74%, respectively. Greater age and having ≥ 1 of the NCDs were associated with greater odds of seeking disease-specific treatment. People in the middle or lower wealth quintiles had lower odds of seeking care than the wealthiest 20% for all conditions. Women with diabetes or chronic respiratory disease had greater odds of seeking disease-specific treatment than men. Muslims, the unmarried, and those with health insurance had greater odds of seeking cancer treatment than Hindus, the married, and the uninsured.ConclusionPredisposing, enabling, and need factors are associated with treatment-seeking status among people reporting the four major NCDs in India, suggesting that multiple processes inform the decision to seek disease-specific care among aware cases. Successfully encouraging and enabling as many people as possible who knowingly live with major NCDs to seek treatment is likely contingent on a multi-pronged approach to healthcare policy-making. The need to improve treatment uptake through accessible healthcare is further underscored by the fact that one-fifth (cancer) to one-third (chronic respiratory disease) of 15–49-year-olds reporting a major NCD have never sought treatment despite being aware of their condition.

Advance care planning among older cancer survivors in the United States.

91 Background: The goal of advance care planning (ACP) is to ensure that end-of-life (EOL) care is consistent with patient wishes and preferences. The ACP is particularly relevant to older adults with cancer due to their high risk of mortality. However, it remains unclear whether older cancer survivors have a higher rate of ACP engagement than general older adults. Methods: We used data from the National Health and Aging Trends Study (NHATS) Round 8, a nationally representative study of adults aged ³65. This cross-sectional analysis included 4,666 participants (1,568 cancer survivors), representing 33.93 million older Americans in 2018. The ACP was defined as having any of the three self-reported elements of ACP: EOL discussion, durable power of attorney (DPOA), or living will/advance directive. Cancer survivors were identified by self-reported cancer in Round 8 or prior rounds. Covariates were self-reported, including age, sex, race, marital status, education level, income, number of comorbidities, number of limitations in activities of daily living (ADL) and probable/possible dementia. We used logistic regressions to examine the association of cancer diagnosis and ACP engagement, adjusting for covariates and complex survey design and weights. Results: Older cancer survivors reported a higher rate of ACP engagement (80.10% vs 73.39), EOL discussion (66.94% vs 60.92%), DPOA (58.56% vs 51.02%) and living will/advance directive (63.34% vs 52.81%), compared to older adults without cancer. However, in adjusted logistic models, there was not significant difference between the two groups in ACP engagement (adjusted OR=1.12, 95% CI: 0.93, 1.36, P=0.22), EOL discussion (adjusted OR=1.08, 95% CI: 0.91, 1.29, P=0.37), DPOA (adjusted OR=1.07, 95% CI: 0.90, 1.28, P= 0.42) or living will/advance directive (adjusted OR=1.20, 95% CI: 1.00, 1.45, P=0.05). The oldest old (&gt;80 years), women, White people, single/not married, with higher education, income, comorbidities and ADL limitations were more likely to engage in ACP (all P&lt;0.01). The associations were similar across models that explored the individual elements of ACP. Conclusions: Despite the high mortality risk, older cancer survivors are not more likely to engage in ACP than the general older adults. About 20% of US older cancer survivors have not engaged in any form of ACP. Hospital, clinic and community strategies to introduce and encourage ACP among older cancer survivors are needed, especially for those minority populations.

Breast Cancer and Bone Mineral Density in a U.S. Cohort of Middle-Aged Women: Associations with Phosphate Toxicity.

Breast cancer is associated with phosphate toxicity, the toxic effect from dysregulated phosphate metabolism that can stimulate tumorigenesis. Phosphate toxicity and dysregulated phosphate metabolism are also associated with bone mineral abnormalities, including excessive bone mineral loss and deposition. Based on shared associations with dysregulated phosphate metabolism and phosphate toxicity, a hypothesis proposed in the present mixed methods-grounded theory study posits that middle-aged women with incidence of breast cancer had a greater magnitude of changes in bone mineral density over time compared with women who remained cancer-free. To test this hypothesis, a mixed-effects model was used to analyze the associations of breast cancer incidence with spinal bone mineral density changes in the U.S. Study of Women's Health Across the Nation. Compared with women in the cohort who remained cancer-free, women who self-reported breast cancer had higher bone mineral density at baseline, but had more rapid losses in bone mineral density during follow-up visits. These findings agree with the hypothesis that a greater magnitude of changes in bone mineral density over time is associated with breast cancer in a cohort of middle-aged women. The findings also have implications for studies investigating dysregulated phosphate metabolism and phosphate toxicity as causative factors of bone metastasis in metastatic breast cancer. Additionally, the authors previously found increased breast cancer risk associated with high dietary phosphate intake in the same cohort of middle-aged women, and more studies should investigate a low-phosphorus diet to reduce bone mineral abnormalities and tumorigenesis in breast cancer patients.

Exploratory profiles of phenols, parabens, and per- and poly-fluoroalkyl substances among NHANES study participants in association with previous cancer diagnoses

BackgroundSome hormonally active cancers have low survival rates, but a large proportion of their incidence remains unexplained. Endocrine disrupting chemicals may affect hormone pathways in the pathology of these cancers.ObjectiveTo evaluate cross-sectional associations between per- and polyfluoroalkyl substances (PFAS), phenols, and parabens and self-reported previous cancer diagnoses in the National Health and Nutrition Examination Survey (NHANES).MethodsWe extracted concentrations of 7 PFAS and 12 phenols/parabens and self-reported diagnoses of melanoma and cancers of the thyroid, breast, ovary, uterus, and prostate in men and women (≥20 years). Associations between previous cancer diagnoses and an interquartile range increase in exposure biomarkers were evaluated using logistic regression models adjusted for key covariates. We conceptualized race as social construct proxy of structural social factors and examined associations in non-Hispanic Black, Mexican American, and other Hispanic participants separately compared to White participants.ResultsPrevious melanoma in women was associated with higher PFDE (OR:2.07, 95% CI: 1.25, 3.43), PFNA (OR:1.72, 95% CI: 1.09, 2.73), PFUA (OR:1.76, 95% CI: 1.07, 2.89), BP3 (OR: 1.81, 95% CI: 1.10, 2.96), DCP25 (OR: 2.41, 95% CI: 1.22, 4.76), and DCP24 (OR: 1.85, 95% CI: 1.05, 3.26). Previous ovarian cancer was associated with higher DCP25 (OR: 2.80, 95% CI: 1.08, 7.27), BPA (OR: 1.93, 95% CI: 1.11, 3.35) and BP3 (OR: 1.76, 95% CI: 1.00, 3.09). Previous uterine cancer was associated with increased PFNA (OR: 1.55, 95% CI: 1.03, 2.34), while higher ethyl paraben was inversely associated (OR: 0.31, 95% CI: 0.12, 0.85). Various PFAS were associated with previous ovarian and uterine cancers in White women, while MPAH or BPF was associated with previous breast cancer among non-White women.Impact StatementBiomarkers across all exposure categories (phenols, parabens, and per- and poly- fluoroalkyl substances) were cross-sectionally associated with increased odds of previous melanoma diagnoses in women, and increased odds of previous ovarian cancer was associated with several phenols and parabens. Some associations differed by racial group, which is particularly impactful given the established racial disparities in distributions of exposure to these chemicals. This is the first epidemiological study to investigate exposure to phenols in relation to previous cancer diagnoses, and the first NHANES study to explore racial/ethnic disparities in associations between environmental phenol, paraben, and PFAS exposures and historical cancer diagnosis.

High Dietary Phosphorus Is Associated with Increased Breast Cancer Risk in a U.S. Cohort of Middle-Aged Women.

Research has shown that high amounts of dietary phosphorus that are twice the amount of the U.S. dietary reference intake of 700 mg for adults are associated with all-cause mortality, phosphate toxicity, and tumorigenesis. The present nested case-control study measured the relative risk of self-reported breast cancer associated with dietary phosphate intake over 10 annual visits in a cohort of middle-aged U.S. women from the Study of Women's Health Across the Nation. Analyzing data from food frequency questionnaires, the highest level of daily dietary phosphorus intake, >1800 mg of phosphorus, was approximately equivalent to the dietary phosphorus levels in menus promoted by the United States Department of Agriculture. After adjusting for participants' energy intake, this level of dietary phosphorus was associated with a 2.3-fold increased risk of breast cancer incidence compared to the reference dietary phosphorus level of 800 to 1000 mg, which is based on recommendations from the U.S. National Kidney Foundation, (RR: 2.30, 95% CI: 0.94-5.61, p = 0.07). Despite the lack of statistical significance, likely due to the small sample size of the cohort, the present nested case-control study's clinically significant effect size, dose-response, temporality, specificity, biological plausibility, consistency, coherence, and analogy with other research findings meet the criteria for inferred causality in observational studies, warranting further investigations. Furthermore, these findings suggest that a low-phosphate diet should be tested on patients with breast cancer.

Variations in the agreement of self-reported cancer: A Danish nationwide study.

Previous studies show that the agreement between self-reported and registry-documented diseases varies across diseases. Few studies have addressed these challenges across site-specific cancer diagnoses. The present study aimed to examine the sensitivity and negative predictive value (NPV) of self-reported cancer in a Danish nationwide survey among adults aged ≥16 years, using registry data as the criterion standard. Moreover, the influence of sociodemographic variables and time since diagnosis on sensitivity was explored using multiple logistic regression models. Self-reported data on cancer history of any site were derived from the Danish National Health Survey 2017 (n = 183 372). Individual-level survey data were linked to data from the Danish Cancer Registry on 10 site-specific cancer diagnoses. NPV was consistently high ≥99.5% across the included cancer diagnoses. In contrast, sensitivity varied greatly and was lowest for cancer in brain/central nervous system (CNS) among both men (25.6%) and women (23.9%) and highest for rectal cancer among men (96.9%) and for breast cancer among women (98.9%). Sensitivity was also relatively low for nonmelanoma skin cancer (41.4% among men; 44.6% among women) and urinary tract cancer (60.0% among men; 60.4% among women). When restricting diagnostic definitions for cancer in brain/CNS and urinary tract cancer to include only malignant neoplasms, sensitivity increased. For several cancer diagnoses, sensitivity decreased with increasing age and lower educational level, whereas conflicting results were observed for time from diagnosis to self-report. Future studies are encouraged to use self-reported cancer history data with caution and for example, include questions on only site-specific cancer diagnoses with high sensitivity.

Using Continuous Passive Assessment Technology to Describe Health and Behavior Patterns Preceding and Following a Cancer Diagnosis in Older Adults: Proof-of-Concept Case Series Study.

Describing changes in health and behavior that precede and follow a sentinel health event, such as a cancer diagnosis, is challenging because of the lack of longitudinal, objective measurements that are collected frequently enough to capture varying trajectories of change leading up to and following the event. A continuous passive assessment system that continuously monitors older adults' physical activity, weight, medication-taking behavior, pain, health events, and mood could enable the identification of more specific health and behavior patterns leading up to a cancer diagnosis and whether and how patterns change thereafter. In this study, we conducted a proof-of-concept retrospective analysis, in which we identified new cancer diagnoses in older adults and compared trajectories of change in health and behaviors before and after cancer diagnosis. Participants were 10 older adults (mean age 71.8, SD 4.9 years; 3/10, 30% female) with various self-reported cancer types from a larger prospective cohort study of older adults. A technology-agnostic assessment platform using multiple devices provided continuous data on daily physical activity via wearable sensors (actigraphy); weight via a Wi-Fi-enabled digital scale; daily medication-taking behavior using electronic Bluetooth-enabled pillboxes; and weekly pain, health events, and mood with online, self-report surveys. Longitudinal linear mixed-effects models revealed significant differences in the pre- and postcancer trajectories of step counts (P<.001), step count variability (P=.004), weight (P<.001), pain severity (P<.001), hospitalization or emergency room visits (P=.03), days away from home overnight (P=.01), and the number of pillbox door openings (P<.001). Over the year preceding a cancer diagnosis, there were gradual reductions in step counts and weight and gradual increases in pain severity, step count variability, hospitalization or emergency room visits, and days away from home overnight compared with 1 year after the cancer diagnosis. Across the year after the cancer diagnosis, there was a gradual increase in the number of pillbox door openings compared with 1 year before the cancer diagnosis. There was no significant trajectory change from the pre- to post-cancer diagnosis period in terms of low mood (P=.60) and loneliness (P=.22). A home-based, technology-agnostic, and multidomain assessment platform could provide a unique approach to monitoring different types of behavior and health markers in parallel before and after a life-changing health event. Continuous passive monitoring that is ecologically valid, less prone to bias, and limits participant burden could greatly enhance research that aims to improve early detection efforts, clinical care, and outcomes for people with cancer.

Prevalence of self-reported cancer based on sexual orientation in the United States: a comparative analysis between lesbian, bisexual, gay, and heterosexual individuals.

Our study aimed to compare the prevalence and likelihood of self-reported (SR) cancer diagnosis between lesbian, gay, and bisexual (LGB) groups and the heterosexual population in the United States between 2017 and 2021. This study analyzed data from the National Health Interview Survey (NHIS) 2017-2021, which included 134,372 heterosexual and 4576 LGB individuals aged 18 and above. The prevalence of any SR cancer and some selected cancers were calculated for the LGB and compared with heterosexual adults. Sexual orientation was used to predict SR cancer diagnosis for each sex using multiple logistic regression, adjusting for other sociodemographic determinants. The unadjusted prevalence of any SR cancer among the LGB population was 9.0%. Lesbian and Bisexual women had higher prevalence of SR cancer of the cervix, uterus, ovary, thyroid, bone, skin melanoma, leukemia, and other blood cancers than Heterosexual women. Gay and Bisexual men had a higher prevalence of SR cancer of the bladder, kidney, skin (non-melanoma, and other kinds), bone, lymphoma, and leukemia than Heterosexual men. After adjusting for other socio-demographic factors, gay men were 1.73 (CI 1.14-2.63, p = 0.01) times more likely than heterosexual men to be diagnosed with cancer, while lesbian women were 2.26 (CI 1.24-4.16, p = 0.009) times more likely to be diagnosed with cancer than heterosexual women. Some sexual minority subgroups are more likely to be diagnosed with cancer than their heterosexual counterparts. As a result, more research and SM-specific intervention efforts should focus on cancer risk assessment, screening, prevention, treatment, and survivorship in SM populations.

Gross hematuria and lower urinary tract symptoms in U.S. Veterans associated with exposure to military burn pits post-deploymentto Iraq and Afghanistan.

Describe rates of hematuria and other lower urinary tract symptoms, including self-reported cancer rates, among Veterans post burn pits emissions exposure during deployment to Iraq and Afghanistan. U.S. post-9/11 Veterans with burn pits emissions exposure confirmed via DD214 forms in the Burn Pits360.org Registry were sent a modified survey. Data were de-identified and anonymously coded. Twenty-nine percent of the 155 respondents exposed to burn pits self-reported seeing blood in their urine. The average index score of our modified AUASIS survey was 12.25 (SD 7.48). High rates of urinary frequency (84%) and urgency (76%) were self-reported. Bladder, kidney, or lung cancers were self-reported in 3.87%. US Veterans exposed to burn pits are self-reporting hematuria and other lower urinary tract symptoms.

Evaluating differences in cancer survivorship care plans experienced by cancer survivors with disabilities.

e18597 Background: Survivorship Care Plans (SCPs) are crucial elements for short- and long-term follow-up care among cancer survivors and have been endorsed by leading oncologic organizations. Yet, limited research exists about the receipt of SCPs among survivors with disabilities who may face additional barriers to access the health care services. Our study examines the association between the disability status and receipt of SCPs after completion of cancer treatment among US adult cancer survivors. Methods: This secondary analysis included cross-sectional, nationally representative, population-based data from the 2021 Behavioral Risk Factor Surveillance System. We included 2110 respondents (aged ≥ 18 years) who self-reported cancer history (other than skin cancer). Outcomes were self-reported receipt of cancer treatment summaries and follow-up care instructions after completion of the cancer treatment. The independent variable was disability status, comprised of six specific disability types (having serious difficulty with hearing, vision, cognition, mobility, self-care, and independent living). We combined disability status into four groups—as having 1) no disability; 2) one disability; 3) two disabilities; and 4) three or more disabilities. We applied recommended sample weights and conducted weighted descriptive statistics and multivariable logistic regression adjusting for self-reported individual-level factors (age, sex, race, marital status, education, health insurance, provider type who provided majority of the care). Results: Overall, 4.2% self-reported as Black, 19.5% Hispanic, 70.0% White, 59.5% women, and 54.5% aged 65+ years. A total of 20.8% of participants reported having one disability, 11.1% two disabilities, and 11.7% reported three or more disabilities. Mobility disability was the most prevalent disability type (27.0%), followed by cognition (14.8%), independent living (14.5%), hearing (12.7%), vision (9.2%), and self-care (6.5%). About 18.0% did not receive follow-up care instructions, and 41.7% did not receive treatment summaries. Overall, 52.8% of survivors reported receiving both follow-up care instructions and treatment summaries. Survivors with three or more disabilities were 0.40 (95% CI 0.27-0.88, p = 0.019) times significantly less likely to report receiving follow-up care instructions than survivors without disabilities. Survivors’ disability status was not significantly associated with reporting the receipt of cancer treatment summaries. Conclusions: Nearly half of the survivors did not receive SCP upon treatment completion, which may lead to poor treatment adherence and deterioration of health. Our findings suggest disparities in follow-up instructions based on disability status, especially for people with multiple disabilities. Effective strategies are necessary to build more equitable cancer survivorship care.

Cervical Cancer Screening Among Older Garifuna Women Residing in New York City.

This study examined the level of adherence to the recommended cervical cancer screening guidelines among Garifuna women residing in New York City, and screening practice association with demographic factors, access to healthcare services, perceptions/barriers to cervical cancer screening, acculturation, identity, and level of screening guideline knowledge. Four hundred Garifuna women were surveyed. The study results reveal low self-reported cervical cancer screening rates (60%), increased age, visiting a Garifuna healer in the past year, perceived benefits of receiving the screening test, and knowledge of the Pap test as having the highest predictive variability for receiving cervical cancer screening. The odds of having a Pap test were significantly lower in older women (age 65years and above) and those visiting a traditional healer within the past year. The study findings provide several implications for developing culturally appropriate interventions aimed to increase the level of cervical cancer screening in this unique immigrant group.
