Social and racial inequalities in diabetes and cancer in the United States. Front Public Health 2023; 11:1178979. [PMID: 37538273 PMCID: PMC10395076 DOI: 10.3389/fpubh.2023.1178979] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2023] [Accepted: 07/05/2023] [Indexed: 08/05/2023] Open
Abstract
Background Cancer and diabetes are among the leading causes of morbidity and mortality worldwide. Several studies have reported diabetes as a risk factor for developing cancer, a relationship that may be explained by associated factors shared with both diseases such as age, sex, body weight, smoking, and alcohol consumption. Social factors referred to as social determinants of health (SDOH) were shown to be associated with the risk of developing cancer and diabetes. Despite that diabetes and social factors were identified as significant determinants of cancer, no studies examined their combined effect on the risk of developing cancer. In this study, we aim at filling this gap in the literature by triangulating the association between diabetes, indices of SDOH, and the risk of developing cancer. Methods We have conducted a quantitative study using data from the Behavioral Risk Factor Surveillance System (BRFSS), whereby information was collected nationally from residents in the United States (US) with respect to their health-related risk behaviors, chronic health conditions, and the use of preventive services. Data analysis using weighted regressions was conducted on 389,158 study participants. Results Our findings indicated that diabetes is a risk factor that increases the likelihood of cancer by 13% (OR 1.13; 95%CI: 1.05-1.21). People of White race had higher odds for cancer compared to African Americans (OR 0.44; 95%CI: 0.39-0.49), Asians (OR 0.27; 95%CI: 0.20-0.38), and other races (OR 0.56; 95%CI: 0.46-0.69). The indices of SDOH that were positively associated with having cancer encompassed unemployment (OR 1.78; 95%CI: 1.59-1.99), retirement (OR 1.54; 95%CI: 1.43-1.67), higher income levels with ORs ranging between 1.16-1.38, college education (OR 1.10; 95%CI: 1.02-1.18), college graduates (OR 1.31; 95%CI: 1.21-1.40), and healthcare coverage (OR 1.44; 95%CI: 1.22-1.71). On the other hand, the indices of SDOH that were protective against having cancer were comprised of renting a home (OR 0.86; 95%CI: 0.79-0.93) and never married (OR 0.73; 95%CI: 0.65-0.81). Conclusion This study offers a novel social dimension for the association between diabetes and cancer that could guide setting strategies for addressing social inequities in disease prevention and access to healthcare.

Lower Utilization of Colorectal Cancer Screening Among Vegetarians, Adventist Health Study-2. JOURNAL OF CANCER EDUCATION : THE OFFICIAL JOURNAL OF THE AMERICAN ASSOCIATION FOR CANCER EDUCATION 2022; 37:1948-1956. [PMID: 34241788 DOI: 10.1007/s13187-021-02065-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Accepted: 06/30/2021] [Indexed: 06/13/2023]
Abstract
This study aims to examine lifestyle predictors of the utilization of colorectal cancer screening. Using modified Poisson regression, we studied self-reported colorectal cancer screening utilization (colonoscopy or fecal occult blood test) with various dietary and lifestyle characteristics among 33,922 subjects aged 51 + years in the Adventist Health Study-2, a large population-based prospective cohort study. According to the multivariable-adjusted models, vegetarians were less likely to report screening: vegans, prevalence ratio (PR) = 0.80 (95% confidence interval 0.77-0.83); lacto-ovo-vegetarians (0.95 [0.93-0.97]); and semi-vegetarians (0.97 [0.94-0.99]) compared to non-vegetarians. Blacks were more likely than non-Blacks to be screened (1.04 [1.02-1.06]) and males were less likely (0.93 [0.92-0.95]) to utilize the screening tests. Older subjects were more likely to be screened, and unmarried and divorced/widowed subjects were less likely to screen. Education, personal income, and BMI were positively associated with screening, with p-value for trend < 0.001 for all three variables. A family history of colorectal cancer was associated with higher screening prevalence (1.15 [1.12-1.17]). Our stratified analyses on race and gender with dietary patterns showed non-Hispanic White vegans (PR = 0.77 [0.74-0.81]) and male vegans (PR = 0.76 [0.72-0.81]) were least likely compliant with colorectal cancer screening (p = 0.009 and p = 0.04, respectively). Vegans may believe that their personal risk for colorectal cancer is low due to their healthy lifestyle, resulting in lack of compliance to colorectal cancer screening. It remains to be seen whether vegans in AHS-2 also experience higher incidence of colorectal cancer or are diagnosed at a later stage.

Abstract
IMPORTANCE Racial disparities in survival outcomes among Black women with hormone receptor-positive breast cancer have been reported. However, the association between individual-level and neighborhood-level social determinants of health on such disparities has not been well studied. OBJECTIVE To evaluate the association between race and clinical outcomes (ie, relapse-free interval and overall survival) adjusting for individual insurance coverage and neighborhood deprivation index (NDI), measured using zip code of residence, in women with breast cancer. DESIGN, SETTING, AND PARTICIPANTS This was a post hoc analysis of 9719 women with breast cancer in the Trial Assigning Individualized Options for Treatment, a randomized clinical trial conducted from April 7, 2006, to October 6, 2010. All participants received a diagnosis of hormone receptor-positive, ERBB2-negative, axillary node-negative breast cancer. The present data analysis was conducted from April 1 to October 22, 2021. MAIN OUTCOMES AND MEASURES A multivariate model was developed to evaluate the association between race and relapse-free interval and overall survival adjusting for insurance and NDI level at study entry, early discontinuation of endocrine therapy 4 years after initiation, and clinicopathologic characteristics of cancer. Median follow-up for clinical outcomes was 96 months. RESULTS A total of 9719 women (4.2% [n = 405] Asian; 7.1% [n = 693] Black; 84.3% [n = 8189] White; 4.4% [n = 403] others/not specified) were included; 9.1% of included women [n = 889] were Hispanic or Latino. Median (SD) age was 56 (9.2) years. In multivariate models, Black race compared with White race was associated with statistically significant shorter relapse-free interval (hazard ratio [HR], 1.39; 95% CI, 1.05-1.84; P = .02) and overall survival (HR, 1.49; 95% CI, 1.10-2.99; P = .009), adjusting for insurance and NDI level at study entry and other factors. Although uninsured status was not associated with clinical outcomes, patients with Medicare (HR, 1.30; 95% CI, 1.01-1.68; P = .04) and Medicaid (HR, 1.44; 95% CI, 1.01-2.05; P = .05) had shorter overall survival compared with those with private insurance. Participants living in neighborhoods in the highest NDI quartile experienced shorter overall survival compared with those in the lowest quartile (HR, 1.34; 95% CI, 1.01-1.77; P = .04), regardless of self-identified race. CONCLUSIONS AND RELEVANCE The findings of this post hoc analysis of a randomized clinical trial suggest that Black women with breast cancer have significantly shorter relapse-free interval and overall survival compared with White women. Early discontinuation of endocrine therapy, clinicopathologic characteristics, insurance coverage, and NDI do not fully explain the observed disparity. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT00310180.

Pre-treatment hematological parameters as a cost effective predictive marker for response to concurrent chemo radiation in locally advanced cervical cancer. Cancer Treat Res Commun 2022; 31:100539. [PMID: 35220070 DOI: 10.1016/j.ctarc.2022.100539] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2020] [Revised: 04/06/2021] [Accepted: 02/20/2022] [Indexed: 12/24/2022]
Abstract
INTRODUCTION Locally advanced cervical cancer is still a major cause of mortality in developing countries. Recently, personalized medicine has changed the treatment paradigm for many solid cancers but no robust biomarkers has yet been validated for predicting response to chemo radiation in cervical cancer patients. AIM To assess the role of hematological parameters as a cost-effective predictive marker of response to concurrent chemo radiation in cervical cancer patients. MATERIALS AND METHOD This is a retrospective analysis of 90 cervical cancer patients treated with concurrent chemo radiation in a tertiary cancer center. Clinical details of the patients were extracted from the case records. For end point evaluation, the pre-treatment levels of hemoglobin, neutrophil, lymphocyte, platelet, platelet lymphocyte ratio (PLR) and neutrophil lymphocyte ratio (NLR) were compared and statistically analyzed between responders and non-responders. The optimal cutoff values of hematological parameters were estimated by the receiver operating characteristics (ROC) curve. RESULT Out of 90 patients, 60 (66.66%) were complete responders and remaining 30 (33.33%) were non-responders. The mean value of platelet, NLR, and PLR was significantly higher in the non-responder group. ROC curve analysis showed the optimal cut-off value of pre-treatment Hb, PLT, NLR and PLR to be 11 gm/dl, 3, 177 × 109/L, and 70 respectively. CONCLUSION Our study suggests that simple hematological markers like NLR, PLT count and PLR could be used as a cost effective pretreatment predictive marker for response to chemo radiation in cervical cancer patients.

Abstract
There are long-standing debates about the benefits of prostate cancer screening. Conflicting trial results and inconsistent recommendations regarding prostate cancer screening in clinical guidelines highlight the importance of patient factors that influence decision making in prostate cancer screening. Attitude is an important factor associated with cancer screening. However, attitudes toward prostate cancer screening among Chinese men are still poorly understood. The objective of the study was to evaluate attitudes toward prostate cancer screening and their association with prostate cancer screening intention among Chinese men. In this community-based study, 340 males were randomly recruited. Three distinct concepts related to prostate cancer screening attitudes were evaluated, including perceived consequences of screening, moral obligation, and anticipated regret. The intention to have prostate cancer screening was asked. Only 5.00% of the study participants had prostate cancer screening before, while 69.71% have an intention to undergo screening in the future. Participants with a high level of anticipated regret also had a high likelihood to have screening in the future, with an adjusted odds ratio (aOR) of 1.82. Participants who had favorable attitudes toward the consequence of participating in prostate cancer screening had a high likelihood to undergo screening, with an aOR of 1.22. Participants who were more concerned about pain and invasion of privacy were less likely to have an intention to have prostate cancer screening, with aORs of 0.53 and 0.57, respectively. To enhance screening intention, public health programs should include components related to anticipated regrets and perceived consequences.

In-Situ-Sprayed Dual-Functional Immunotherapeutic Gel for Colorectal Cancer Postsurgical Treatment. Adv Healthc Mater 2021; 10:e2100862. [PMID: 34347370 DOI: 10.1002/adhm.202100862] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2021] [Revised: 07/14/2021] [Indexed: 12/13/2022]
Abstract
Surgery remains the most preferred treatment options for colorectal cancer (CRC). Paradoxically, local recurrence and distant metastasis are usually accelerated postsurgery as a consequence of local and systemic immunosuppression caused by surgery. Therefore, modulating tumor postoperative immune microenvironment and activating systemic antitumor immunity are necessary supplementaries for CRC therapy. Here, an in-situ-sprayed immunotherapeutic gel loaded with anti-OX40 antibody (iSGels@aOX40) is reported for CRC postsurgical treatment. The iSGel is formed instantly after spraying with strong adhesion ability via crosslinking between tannic acid (TA) and poly(l-glutamic acid)-g-methoxy poly(ethylene glycol)/phenyl boronic acid (PLG-g-mPEG/PBA). TA not only serves as one component of the iSGel but also relieves the postsurgical immunosuppressive microenvironment by inhibiting the activity of cyclo-oxygenase-2 (COX-2). The aOX40 serves as an immune agonistic antibody and is released from the iSGel in a constant manner lasting for over 20 days. In a subcutaneous murine CRC model, the iSGels@aOX40 results in complete inhibition on tumor recurrence. In addition, the cured mice show resistance to tumor re-challenge, suggesting that immune memory effects are established after the iSGels@aOX40 treatment. In an orthotopic CRC peritoneal metastatic model, the iSGels@aOX40 also remarkably inhibits the growth of the abdominal metastatic tumors, suggesting great potential for clinical CRC therapy.

Cancer Screening Knowledge and Behavior in a Multi-Ethnic Asian Population: The Singapore Community Health Study. Front Oncol 2021; 11:684917. [PMID: 34476210 PMCID: PMC8406849 DOI: 10.3389/fonc.2021.684917] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2021] [Accepted: 07/07/2021] [Indexed: 12/24/2022] Open
Abstract
Background Cancer has become the leading cause of mortality in Singapore and among other Asian populations worldwide. Despite the presence of National Cancer Screening programmes in Singapore, less than half of the population has had timely screening according to guidelines. The underlying factors of poor cancer screening rates and health outcomes among Asian ethnic groups remain poorly understood. We therefore examined cancer screening participation rates and screening behavior in a multi-ethnic Singapore population. Methods We collected data from 7,125 respondents of the 2015–2016 Singapore Community Health Study. Factors associated with cervical, breast, and colorectal cancer screening were evaluated using modified Poisson regression. Adjusted prevalence ratios were computed with 95% confidence intervals after adjusting for confounders. Results The mean age of the respondents was 57.7 ± 10.9 years; 58.9% were female and were predominately Chinese (73.0%), followed by Malay (14.2%), and Indian (10.9%). Less than half of the respondents in the recommended age groups had undergone cancer screening (cervical, 43%; breast, 35.1%; colorectal, 27.3%). Malay respondents were significantly less likely to screen as recommended for cervical (aPR = 0.75, CI = 0.65–0.86, p < 0.001), breast (aPR = 0.83, CI = 0.68–0.99, p = 0.045), and colorectal cancer (aPR = 0.55, CI = 0.44–0.68, p < 0.001), as compared to Chinese respondents. Respondents who had obtained lower secondary level education were 42% more likely to screen for cervical cancer (aPR = 1.42, CI = 1.23–1.64, p < 0.001), and 22% more likely to screen for breast cancer (aPR = 1.22, CI = 1.02–1.46, p = 0.032), compared to those with primary level education and below. Respondents with a household income ≥S$10,000/month were 71% more likely to screen for breast cancer (aPR = 1.71, CI = 1.37–2.13, p < 0.001), as compared with <$2,000/month. Conclusions Ethnicity and socio-economic status were significantly associated with lower uptake of cancer screening tests in Singapore. To improve the screening uptake among disadvantaged groups, a multi-faceted approach is needed that addresses the barriers to screening such as the adequacy of subsidy schemes and ethnic differences.

Postpartum HPV Vaccination Rate and Differences in Background Characteristics Between HPV Vaccinated and Unvaccinated Postpartum Women: Strict Monitoring and Follow-Up of Postpartum HPV Vaccination Program. Front Immunol 2021; 12:626582. [PMID: 34054800 PMCID: PMC8149888 DOI: 10.3389/fimmu.2021.626582] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2020] [Accepted: 04/28/2021] [Indexed: 12/26/2022] Open
Abstract
There is a need to increase the vaccine completion rates in women who have already received human papillomavirus (HPV) vaccines. With vaccines requiring multiple doses, designing a vaccination control program and increasing the proportion of women who complete vaccination are critical and remain as huge challenges. Currently, there are no published reports on the differences in the background characteristics between postpartum women who are vaccinated or unvaccinated against HPV. This study aimed to determine the vaccination rates of the second and third doses of HPV vaccination utilizing an achievable HPV vaccination program in postpartum women. In this retrospective study, 243 postpartum women attending Chiayi Chang Gung Memorial Hospital between March and September 2014 were enrolled. These women were classified into two groups: one group received the HPV vaccine under a practical, controlled postpartum HPV vaccination program, and the other group did not. The rates for the second and third rounds of HPV vaccination in postpartum women were calculated. The differences in the background characteristics between the two groups were determined using the Student’s t test, chi-square test or Fisher’s exact test, and the multiple logistic models, as appropriate. Under the controlled postpartum HPV vaccination program, the completion rate for the three doses of postpartum HPV vaccination was 97.2%. Significant differences were observed according to maternal age, gender of the newborn, and postpartum Pap smear results between the two groups in our study. In conclusion, the controlled postpartum HPV vaccination program is a reasonable method for achieving an excellent completion rate for the three doses of postpartum HPV vaccination and may be a good model for any multiple-dose vaccination protocol.

Abstract
IMPORTANCE The Patient Protection and Affordable Care Act broadened insurance coverage, partially through voluntary state-based Medicaid expansion. OBJECTIVE To determine whether patients with higher-risk prostate cancer residing in Medicaid expansion states were more likely to receive treatment after expansion compared with patients in states electing not to pursue Medicaid expansion. DESIGN, SETTING, AND PARTICIPANTS This population-based cohort study included 15 332 patients diagnosed with higher-risk prostate cancer (ie, grade group >2; grade group 2 with prostate-specific antigen levels >10 ng/mL; or grade group 1 with prostate-specific antigen levels >20 ng/mL) from January 2010 to December 2016 aged 50 to 64 years who were candidates for definitive treatment. Patients residing in states that partially expanded Medicaid coverage before 2010 (ie, California and Connecticut) and those with diagnosis not confirmed by histology were excluded. Data were collected from the Surveillance, Epidemiology, and End Results Program. Data were analyzed between August and December 2019. EXPOSURE State-level Medicaid expansion status. MAIN OUTCOMES AND MEASURES Insurance status before and after expansion, treatment with prostatectomy or radiation therapy (including brachytherapy), treatment trends over time. RESULTS Of 15 332 patients, 7811 (50.9%) lived in expansion states (mean [SD] age, 59.1 [3.8] years; 5532 [71.9%] non-Hispanic White), and 7521 (49.1%) lived in nonexpansion states (mean [SD] age, 59.0 [3.9] years; 3912 [52.1%] non-Hispanic White). Residence in an expansion state was associated with higher pre-expansion levels of Medicaid coverage (292 [8.1%] vs 161 [3.8%]; odds ratio [OR], 2.12; 95% CI, 1.78 to 2.53) and lower likelihood of being uninsured (136 [3.2%] vs 38 [1.1%]; OR, 0.28; 95% CI, 0.15 to 0.54). After expansion, there was no difference in trends in treatment receipt between expansion and nonexpansion states (change, -0.39%; 95% CI, -0.11% to 0.28%; P = .25). Patients with private or Medicare coverage were more likely to receive treatment vs those with Medicaid or no coverage across racial/ethnic groups (eg, Black patients with coverage: OR, 2.30; 95% CI, 1.68 to 3.10; Black patients with no coverage: OR, 1.48; 95% CI, 1.09 to 2.00; P < .001). Medicaid patients were not more likely to be treated compared with those without insurance (737 [78.8%] vs 435 [79.5%]; OR, 0.97; 95% CI, 0.76 to 1.25). CONCLUSIONS AND RELEVANCE In this cohort study, state-level expansion of Medicaid was associated with increased Medicaid coverage for men with higher-risk prostate tumors but did not appear to affect treatment patterns at a population level. This may be related to the finding that Medicaid coverage was not associated with increased treatment rates compared with those without insurance.

Identifying an association between socio-demographic factors and breast cancer screening adherence in a federally qualified health centre sample in the United States. A retrospective, cross-sectional study. HEALTH & SOCIAL CARE IN THE COMMUNITY 2020; 28:1772-1779. [PMID: 32304270 DOI: 10.1111/hsc.13002] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/12/2019] [Revised: 03/12/2020] [Accepted: 03/25/2020] [Indexed: 06/11/2023]
Abstract
Federally Qualified Health Centres (FQHC) are community-based centres in the United States, intended to fill a gap in care for underserved populations, including Medicaid patients and the homeless. Because of the Affordable Care Act, passed into law in 2010, there was a 29% increase in Medicaid enrolees nationally. One service offered at FQHCs is breast cancer screening. Breast cancer screening has been shown to have the lowest adherence levels among low-income women and homeless women. As they serve patients with socio-economic barriers, FQHCs are a vital resource in ensuring access to such screening. This study aimed to identity an association between socio-demographic factors and breast cancer screening adherence in FQHC patients that included the homeless. This exploratory, cross-sectional, retrospective study looked at encounter level data from a FQHC in a major metropolitan (Chicago, IL) area from January 1st, 2017 through December 31st, 2018. Data were collected in January of 2019. This was a convenience sample. Association was tested through bivariate chi-square tests and multivariate logistic regression analysis, investigating the association between socio-demographic characteristics and compliance (Yes/No) for breast cancer screening. Results showed age (55-59; 65-69) and homeless status (doubling-up, transitional) showed a positive association with breast cancer screening, while insurance status (self-pay) had a negative association. Age, homeless status and insurance type were significantly associated with adherence. Demographic characteristics in the homeless population can be used to identify nonadherence.

Abstract
BACKGROUND Early detection of breast cancer can improve survival rates and decrease mortality rates. This study investigates whether there are significant differences in participation in breast screening among women born in Muslim countries compared to women born in Non-Muslim countries and Australia. METHODS Screening data from January 1st, 2000 to December 31st, 2013 from the Breast Screen Victoria Registry (BSV) was linked with hospital records from the Victorian Admitted Episodes Dataset (VAED). Countries having more than 50% of their population as Muslim were categorised as Muslim countries. Age adjusted rates were calculated for women born in Muslim and Non-Muslim countries and compared with the Australian age adjusted rates. Logistic regression assessed the association between screening status and other factors which include country of birth, marital status, age and socio-economic status. RESULTS Women born in Muslim countries (Odds Ratio (OR) = 0.70, 95%CI = 0.68-0.72) and in other Non-Muslim countries (OR = 0.87, 95%CI = 0.86-0.88) had lower odds of participation in breast screening than Australian born women. Women aged 60-64 years (OR = 1.42, 95%CI = 1.40-1.44) had higher odds of participation in the BreastScreen program than 50-54 age group. CONCLUSION This study provides valuable insights to understanding breast screening participation among women born in Muslim countries residing in Victoria. This population level study contributes to the broader knowledge of screening participation of women born in Muslim countries, an understudied population group in Australia and across the world. This study has implications for breast screening programs as it highlights the need for culturally sensitive approaches to support breast screening participation among women born in Muslim countries.

Abstract
Black men suffer inequalities in health and health-care outcomes relative to other racial/ethnic groups, requiring well-informed efforts for health promotion. Fewer Black men have a usual source of health care, which may be a contributor to these disparities. Increasing access to and the likelihood of a usual source of care among Black men are important to address health and health-care disparities. In this focus group study, we sought to better understand how Black men think about primary care and usual sources of care. A total of six focus groups were conducted with N = 25 men. Groups were a mix of men with and without a usual source of care. Several themes were identified through analysis of the data regarding factors that contribute to Black men going to the doctor. Themes identified in the data analysis included Lack of Health Insurance as a Barrier to Establishing Usual Source of Care; Family Promoting Health Care Use; Relationship With Doctor, Trust, and Empowerment; Age and Maturity in Health Promotion; and Positive Tone of Messaging. Future research should explore if similar findings are obtained among men in different regions of the United States or between Black men of different backgrounds. Taking a step beyond this research, specifically, future research can also examine the impact of particular health messages/messaging on Black men’s health-care-seeking behaviors.

Abstract
The Hunan provincial government has implemented a free breast cancer screening program for rural women aged 35 to 64 years from 2016, under a 2015 policy aimed at of poverty eradication and improving women's health in China. However, there has been no population study of the breast cancer screening program in China to date, especially considering exploring differences related to the area's poverty status. We explored differences in risk factors, clinical examination results, and clinicopathological features among breast cancer patients in poor compared with non-poor counties in rural areas of Hunan province from 2016 to 2018 using χ and Fisher's exact test, and multivariate logistic regression analysis. A total of 3,151,679 women from rural areas participated in the screening program, and the breast cancer prevalence was 37.09/10. Breast cancer prevalence was lower in poor (29.68/10) than in non-poor counties (43.13/10). There were differences between breast cancers in poor and non-poor counties in terms of cysts, margins, internal echo, blood flow in solid masses in the right breast on ultrasound examination, lump structure in mammograms, and clinicopathological staging and grading in pathological examinations. Breast cancer in poor counties was more likely to be diagnosed at later stages as determined by ultrasound, mammography, and pathological examinations. Furthermore, indexes of the breast screening program including early detection, prevalence, pathological examination, and mammography examination were lower in poor compared with non-poor counties. Multivariate logistic regression analysis showed that education, ethnicity, reproductive history and the year 2017 were associated with an increased risk of breast cancer in poor counties (odds ratio >1, P < .05). In conclusion, women in poor areas were more likely to be diagnosed with breast cancer at a later stage compared with women in non-poor areas. Women in poor areas of Hunan province should therefore have better access to diagnostic and clinical services to help rectify this situation.

Endocrine Therapy Nonadherence and Discontinuation in Black and White Women. J Natl Cancer Inst 2019; 111:498-508. [PMID: 30239824 PMCID: PMC6510227 DOI: 10.1093/jnci/djy136] [Citation(s) in RCA: 63] [Impact Index Per Article: 12.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2017] [Revised: 06/08/2018] [Accepted: 07/10/2018] [Indexed: 12/26/2022] Open
Abstract
BACKGROUND Differential use of endocrine therapy (ET) by race may contribute to breast cancer outcome disparities, but racial differences in ET behaviors are poorly understood. METHODS Women aged 20-74 years with a first primary, stage I-III, hormone receptor-positive (HR+) breast cancer were included. At 2 years postdiagnosis, we assessed nonadherence, defined as not taking ET every day or missing more than two pills in the past 14 days, discontinuation, and a composite measure of underuse, defined as either missing pills or discontinuing completely. Using logistic regression, we evaluated the relationship between race and nonadherence, discontinuation, and overall underuse in unadjusted, clinically adjusted, and socioeconomically adjusted models. RESULTS A total of 1280 women were included; 43.2% self-identified as black. Compared to white women, black women more often reported nonadherence (13.7% vs 5.2%) but not discontinuation (10.0% vs 10.7%). Black women also more often reported the following: hot flashes, night sweats, breast sensitivity, and joint pain; believing that their recurrence risk would not change if they stopped ET; forgetting to take ET; and cost-related barriers. In multivariable analysis, black race remained statistically significantly associated with nonadherence after adjusting for clinical characteristics (adjusted odds ratio = 2.72, 95% confidence interval = 1.75 to 4.24) and after adding socioeconomic to clinical characteristics (adjusted odds ratio = 2.44, 95% confidence interval = 1.50 to 3.97) but was not independently associated with discontinuation after adjustment. Low recurrence risk perception and lack of a shared decision making were strongly predictive of ET underuse across races. CONCLUSIONS Our results highlight important racial differences in ET-adherence behaviors, perceptions of benefits/harms, and shared decision making that may be targeted with culturally tailored interventions.

Social Disadvantage, Healthcare Utilization, and Colorectal Cancer Screening: Leveraging Longitudinal Patient Address and Health Records Data. Cancer Epidemiol Biomarkers Prev 2018; 27:1424-1432. [PMID: 30135072 PMCID: PMC6279539 DOI: 10.1158/1055-9965.epi-18-0446] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2018] [Revised: 07/11/2018] [Accepted: 08/17/2018] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Social disadvantage predicts colorectal cancer outcomes across the cancer care continuum for many populations and places. For medically underserved populations, social disadvantage is likely intersectional-affecting individuals at multiple levels and through membership in multiple disadvantaged groups. However, most measures of social disadvantage are cross-sectional and limited to race, ethnicity, and income. Linkages between electronic health records (EHR) and external datasets offer rich, multilevel measures that may be more informative. METHODS We identified urban safety-net patients eligible and due for colorectal cancer screening from the Parkland-UT Southwestern PROSPR cohort. We assessed one-time screening receipt (via colonoscopy or fecal immunochemical test) in the 18 months following cohort entry via the EHR. We linked EHR data to housing and Census data to generate measures of social disadvantage at the parcel- and block-group level. We evaluated the association of these measures with screening using multilevel logistic regression models controlling for sociodemographics, comorbidity, and healthcare utilization. RESULTS Among 32,965 patients, 45.1% received screening. In adjusted models, residential mobility, residence type, and neighborhood majority race were associated with colorectal cancer screening. Nearly all measures of patient-level social disadvantage and healthcare utilization were significant. CONCLUSIONS Address-based linkage of EHRs to external datasets may have the potential to expand meaningful measurement of multilevel social disadvantage. Researchers should strive to use granular, specific data in investigations of social disadvantage. IMPACT Generating multilevel measures of social disadvantage through address-based linkages efficiently uses existing EHR data for applied, population-level research.

Abstract
Background: Rates of hepatitis C virus (HCV) infection are markedly higher for baby boomers compared with other birth cohorts, and they are now recommended for universal one-time screening. This study examines HCV screening rates and predictors for four birth cohorts [born <1945, born 1945-1965 (baby boomers), born 1966-1985, and born >1985] of a nationally representative sample over time.Methods: We used data from the 2013-2015 National Health Interview Surveys, an annual weighted survey of the U.S. civilian noninstitutionalized population. We assessed HCV screening prevalence stratified birth cohort with bivariate and multivariable logistic regression analyses.Results: There were 15,100 participants born <1945, 28,725 baby boomers, 28,089 born 1966-1985, and 13,296 born >1985 in the final analytic sample. Screening was 11.5%-12.8% for baby boomers. The second youngest birth cohort was similar to baby boomers (13.7%-14.9%), whereas the older birth cohort was screened less. After excluding participants who typically have higher rates of HCV screening than the general population, we developed a multivariable model of the general population. In the final model for baby boomers the odds of HCV screening increased significantly with each subsequent year (OR=1.20; 95% CI=1.05-1.38 and OR=1.31; 95% CI=1.13-1.52). HCV screening was also significantly associated with age, gender, and race/ethnicity in baby boomers.Conclusions: While HCV screening is increasing over time, these increases are minimal and there is substantial room for improvement.Impact: Future research should develop interventions to increase HCV screening with special focus on groups demonstrating significantly lower screening rates, such as Hispanics and females.

Abstract
Objective: Ageing population and noticeable changes in lifestyle in developing countries like Iran caused an
increase in cancer incidence. This requires organized cancer prevention and screening programs in population level,
but most importantly community should be aware of these programs and willing to use them. This study explored
existing evidence on public awareness and practice, as well as, adherence to cancer screening in Iranian population.
Methods: Major English databases including Web of Science, PubMed, Scopus, and domestic Persian databases i.e.,
SID, Magiran, and Barakat search engines were searched. All publications with focus on Iranian public awareness
about cancer prevention, screening, and early detection programs which were published until August 2015, were
explored in this systematic review. For this purpose, we used sensitive Persian phrases/key terms and English keywords
which were extracted from medical subject headings (MeSH). Taking PRISMA guidelines into considerations eligible
documents, were evaluated and abstracted by two separate reviewers. Results: We found 72 articles relevant to this
topic. Screening tests were known to, or being utilized by only a limited number of Iranians. Most Iranian women relied
on physical examination particularly self-examination, instead of taking mammogram, as the most standard test to find
breast tumors. Less than half of the average-risk adult populations were familiar with colorectal cancer risk factors and
its screening tests, and only very limited number of studies reported taking at least one time colonoscopy or FOBT,
at most 5.0% and 15.0%, respectively. Around half of women were familiar with cervical cancer and Pap-smear test
with less than 45% having completed at least one lifetime test. The lack of health insurance coverage was a barrier to
participate in screening tests. Furthermore some people would not select to be screened only because they do not know
how or where they can receive these services. Conclusion: Low awareness and suboptimal use of screening tests in
Iran calls for effective programs to enhance intention and compliance to screening, improving the patient-physician
communication, identifying barriers for screening and providing tailored public awareness and screening programs.

The Relation among Prostate Cancer Knowledge and Psychosocial Factors for Prostate Cancer Screening among African American Men: a Correlational Study. AIMS Public Health 2017; 4:446-465. [PMID: 30155498 PMCID: PMC6111273 DOI: 10.3934/publichealth.2017.5.446] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2017] [Accepted: 10/17/2017] [Indexed: 11/18/2022] Open
Abstract
African American (AA) men face disproportionately higher rates of prostate cancer (PCa) in comparison to other races. In addition, higher mortality rates from PCa amongst AA men signifies PCa as a formidable health disparity. Inconsistent PCa screening guidelines among medical organizations, further clouds one's decision on receiving a PCa screening. Examining various relations among factors which influence PCa screening may provide insight into their decision whether or not to receive a PCa screening. The purpose of the study was to examine the presence of associations among PCa knowledge, psychosocial factors, and PCa screening over a six month time frame. There were 76 participants at baseline, intervention group (n = 37) and control group (n = 35) and 54 participants, intervention group (n = 26) and control group (n = 28) remained at the 6 month follow up. At the six month follow up, the control group was more likely to have not received a PCa screening and the intervention group was more likely to have received a PCa screening, p < 0.01. PCa knowledge scores rose from 49% to 71%, intervention group, and 52% to 58%, control group. Significant associations were found among the following covariates, age and religion (rs = 0.499, p < 0.01), income and education (rs = 0.535, p < 0.01), income and healthcare coverage (rs = 0.528, p < 0.01), income and PCa knowledge at 6 months (rs = 0.424, p < 0.01), PCa screening and religion (rs = 0.353, p < 0.01), healthcare empowerment and preparation for decision making (rs = 0.421, p < 0.01), decisional self-efficacy and active surveillance knowledge (rs = 0.377, p < 0.01), and active surveillance knowledge and PCa knowledge (rs = 0.497, p < 0.01). The study revealed associations among PCa knowledge and psychosocial factors regarding a decision for PCa screening among the PCa high risk group, AA men.

Travel Times for Screening Mammography: Impact of Geographic Expansion by a Large Academic Health System. Acad Radiol 2017; 24:1125-1131. [PMID: 28483308 DOI: 10.1016/j.acra.2017.03.010] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2017] [Accepted: 03/12/2017] [Indexed: 10/19/2022]
Abstract
RATIONALE AND OBJECTIVES This study aims to assess the impact of off-campus facility expansion by a large academic health system on patient travel times for screening mammography. MATERIALS AND METHODS Screening mammograms performed from 2013 to 2015 and associated patient demographics were identified using the NYU Langone Medical Center Enterprise Data Warehouse. During this time, the system's number of mammography facilities increased from 6 to 19, reflecting expansion beyond Manhattan throughout the New York metropolitan region. Geocoding software was used to estimate driving times from patients' homes to imaging facilities. RESULTS For 147,566 screening mammograms, the mean estimated patient travel time was 19.9 ± 15.2 minutes. With facility expansion, travel times declined significantly (P < 0.001) from 26.8 ± 18.9 to 18.5 ± 13.3 minutes (non-Manhattan residents: from 31.4 ± 20.3 to 18.7 ± 13.6). This decline occurred consistently across subgroups of patient age, race, ethnicity, payer status, and rurality, leading to decreased variation in travel times between such subgroups. However, travel times to pre-expansion facilities remained stable (initial: 26.8 ± 18.9 minutes, final: 26.7 ± 18.6 minutes). Among women undergoing mammography before and after expansion, travel times were shorter for the postexpansion mammogram in only 6.3%, but this rate varied significantly (all P < 0.05) by certain demographic factors (higher in younger and non-Hispanic patients) and was as high as 18.2%-18.9% of patients residing in regions with the most active expansion. CONCLUSIONS Health system mammography facility geographic expansion can improve average patient travel burden and reduce travel time variation among sociodemographic populations. Nonetheless, existing patients strongly tend to return to established facilities despite potentially shorter travel time locations, suggesting strong site loyalty. Variation in travel times likely relates to various factors other than facility proximity.

Abstract
Colorectal cancer (CRC) is highly preventable when CRC screening is utilized, yet CRC screening completion among African American men is relatively low and their mortality rates remain 50% higher juxtaposed to their White counterparts. Since a growing body of literature indicates masculinity, racism, and social support each have strong influences on CRC screening uptake, this systematic review examined the connections between these three sociocultural factors and CRC screening uptake among African American men. Potential studies were retrieved from MEDLINE, CINAHL, EMBASE, and PsycINFO. Cited reference searching for the final sample was employed to identify and assess additional studies for inclusion using Scopus. The methodological quality of the reviewed evidence was also evaluated. Nineteen studies met inclusion/exclusion criteria. Thirteen studies employed nonexperimental research designs; a quasi-experimental design was present in four, and two utilized experimental designs. Studies were published between 2000 and 2014; the majority between 2009 and 2013. Social support was most frequently addressed (84%) while masculinity and racism were equally studied with paucity (11%) for their influence on CRC screening. After evaluating conceptual and methodological characteristics of the studies, 42% fell below average in quality and rigor. The need for increased attention to the sociocultural correlates of CRC screening for African American men are highlighted in this systematic review, and important recommendations for research and practice are provided. Alongside a call for more rigorous research, further research examining the influence of masculinity and racism on CRC screening completion among African American men is warranted.

Abstract
Studies have shown timely screening, diagnosis, and treatment of breast cancer reduces mortality rates. The objective of this study is to evaluate the overall timeliness of breast cancer diagnosis and treatment for Delawarean women using the Centers for Disease Control and Prevention’s (CDC) National Breast and Cervical Cancer Early Detection Program’s (NBCCEDP) recommendations of 60 days maximum for screening to diagnosis and 60 days maximum for diagnosis to treatment. This study analyzed Delaware Cancer Registry (DCR) data for female Delawarean breast cancer patients diagnosed in 2010 who had valid screening, diagnosis, and treatment dates. Calculations of three time intervals were performed: screening to diagnosis (Time A), diagnosis to treatment (Time B), and screening to treatment (Time C). The mean and median for Time Intervals A (21.2 days, 17.0 days), B (27.8 days, 25.0 days), and C (49.0 days, 42.0 days) met CDC recommendations. Our results show most Delawarean women who had valid screening, diagnosis, and treatment dates received a diagnosis within 60 days of screening and first course of treatment occurred within 60 days of diagnosis and therefore met the NBCCEDP recommendations.

Abstract
BACKGROUND Metastatic pancreatic cancer (mPC) is associated with low survival, with less than 10% of patients surviving 5 years. Recent therapies improve survival outcomes where few alternative therapies exist, but few economic analyses measure the value of survival gains attributable to new therapies. OBJECTIVE To estimate the value of survival gains in advanced or mPC attributable to the introduction of novel treatment regimens. METHODS Multivariate Cox proportional hazards models were used to estimate real-world survival gains associated with the introduction of gemcitabine (GEM) for patients diagnosed with stage IV or unstaged mPC in the Surveillance, Epidemiology, and End Results Program cancer registries. Then, evidence from clinical trials was used to evaluate the survival gains associated with nab-paclitaxel + gemcitabine (nP +GEM) and FOLFIRINOX (FFX) relative to GEM. The survival estimates and clinical trial evidence were used to calibrate an economic model and assess the cumulative value of survival gains in mPC to patients. Costs of treatment were calculated based on published cost-effectiveness studies. RESULTS We estimated that the introduction of GEM in 1996 was associated with a hazard ratio of 0.920 (P < 0.05) and an increase in median survival from 3.1 to 4.5 months. Results suggested that the value of survival gains attributable to GEM equaled about $71,000 per patient, while the value attributable to nP + GEM was an additional $56,700. Estimates for the value of survival gains per patient, net of total incremental lifetime treatment costs (drugs, adverse events, and other costs), were $50,294 for GEM and an additional $31,900 for nP + GEM. Clinical trials and cost-effectiveness studies reported an overall survival gain from FFX that was larger than, but statistically similar to, nP + GEM and had greater risk of adverse events and total incremental costs. We estimated that the total value of survival gains to mPC patients, net of total costs, associated with GEM was up to $47.6 billion, and the additional values attributable to nP+GEM and FFX were up to $39.0 billion and $26.3 billion, respectively. CONCLUSIONS Historically, mPC patients have faced high disease burden and had few treatment options. Treatments introduced since 1996 have led to improved survival, with varying costs associated with treatment and adverse events. Accounting for total incremental costs, the majority of the value of survival gains from GEM and nP+GEM was retained by mPC patients, highlighting the value of innovation in settings where survival is low and few alternative therapies exist.

Abstract
The aim of this study is examine trends in breast and colorectal cancer screening in the U.S. by race, healthcare coverage, and socio-economic status (SES) before the Great Recession (2003-2005), during the recession (2007-2009), and post-recession/Affordable Care Act (ACA) period (2010 - 2012). Data on a representative sample of U.S. adults was obtained from the Behavioral Risk Factor Surveillance System (BRFSS). Breast and colorectal cancer screening were defined in line with U.S. Preventative Services Task Force guidelines, and survey weighted statistical methods were utilized to analyze trends in cancer screening among 1,858,572 BRFSS participants. Overall, 83% of women received mammograms in the past 2 years, while 95% of adults received colorectal cancer screening in the past 10 years. Compared with the pre-recession period, the odds of colorectal screening within 5 years were slightly higher during the recession (OR: 1.05, 95% CI: 1.03-1.08) but significantly lower in the post-recession/ACA period (OR: 0.73, 95% CI: 0.72-0.75). Odds of mammography screening were lower during (OR: 0.94,95% CI: 0.91-0.96) and post-recession/ACA period (OR: 0.80, 95% CI: 0.78-0.82). Breast cancer screening rates declined in the recession and post-recession, while colorectal cancer screening rates increased during the recession and decreased post-recession. Low SES adults and those without healthcare coverage were the least likely to receive screening.

Abstract
Colorectal cancer screening is one of the few cancer screenings with an "A" rating from the US Preventive Services Task Force, meaning that the procedure confers a substantial health benefit. However, 40 percent of people who should receive colorectal cancer screenings do not receive them. Colonoscopies are the most thorough method of screening because they allow physicians to view the entire length of the colon and remove polyps as needed. Billing methods that distinguish between screening and therapeutic procedures have kept expected colonoscopy costs high. However, the Affordable Care Act partially closed the so-called colonoscopy loophole and reduced expected out-of-pocket expenses for all Medicare beneficiaries. Using data from the Behavioral Risk Factor Surveillance System, we found that annual colonoscopy rates among men ages 66-75 increased significantly (by 4.0 percentage points) after the Affordable Care Act policy change, and we found some evidence of even larger increases among socioeconomically disadvantaged men. We found no significant increases among women, a result that may be explained by health behavior and other factors and that requires further study. Our research indicates that cost may be an important barrier to colorectal cancer screening, at least among men, and that making further policy changes to close remaining loopholes may improve screening rates.

Abstract
PURPOSE Many studies have suggested that disparities exist in the use of medical screening tests. The purpose of this study was to assess racial disparities in screening mammography in the United States via a systematic review and meta-analysis. METHODS We searched MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Scopus for comparative studies published between 1946 and 2015 comparing utilization of mammography among various racial groups. Two independent reviewers extracted data and appraised study. Meta-analysis was conducted when appropriate using the random-effects model. RESULTS A total of 5,818,380 patients were included across 39 relevant studies; 43.1% of patients were white, 33.3% were black, 17.4% were Hispanic, and 6.2% were Asian/Pacific Islander. Black and Hispanic populations had lower odds of utilizing screening mammography when compared with the white population (odds ratio [OR] = 0.81; 95% confidence interval [CI], 0.72-0.91; I2 = 89.4% and OR = 0.83; 95% CI, 0.74-0.93, respectively). For African Americans, these disparities were present in both the 40 to 65 age group and the >65 age group; for Hispanics, these differences were present only in the 40 to 65 age group. There was no difference in mammography utilization between Asians/Pacific Islanders and whites (OR = 1.82; 95% CI, 0.09-38.41). CONCLUSIONS Racial disparities in utilization of screening mammography are evident in black and Hispanic populations in the United States. Further studies are needed to understand reasons for disparities, trends over time, and the effectiveness of interventions targeting these disparities.

Abstract
OBJECTIVES Considerable disparities in breast cancer screening exist between Hispanic and non-Hispanic white (NHW) women. Identifying and quantifying the factors contributing to these racial-ethnic disparities can help shape interventions and policies aimed at reducing these disparities. This study, for the first time, identified and quantified individual-level sociodemographic and health-related factors that contribute to racial-ethnic disparities in breast cancer screening using the nonlinear Blinder-Oaxaca decomposition method. METHODS Analysis of the retrospective pooled cross-sectional Medical Expenditure Panel Survey data from 2000 to 2010 was conducted. Women aged 40 years and older were included in the study. Logistic regressions were used to estimate racial-ethnic disparities in breast cancer screening. Nonlinear Blinder-Oaxaca decomposition method was used to identify and quantify the contribution of each individual-level factor toward racial-ethnic disparities. RESULTS Based on the unadjusted analyses, Hispanic women had lower odds of receiving mammogram screening (MS) (odds ratio [OR]: 0.74; 95% confidence interval [CI]: 0.69-0.80) and breast cancer screening (OR: 0.75; 95% CI: 0.70-0.81) as compared with NHW women. However, the relationship reversed in adjusted analyses, such that Hispanic women had higher odds of receiving MS (OR: 1.27; 95% CI: 1.16-1.40) and breast cancer screening (OR: 1.28; 95% CI: 1.17-1.40) as compared with NHW women. The Blinder-Oaxaca decomposition estimated that improving insurance status, access to care, education, and income will considerably increase screening rates among Hispanic women. CONCLUSIONS The study projects that improving health care access and health education will considerably increase breast cancer screening compliance among Hispanic women. Policies like the Affordable Care Act, and patient navigation and health education interventions, might considerably reduce screening disparities in the Hispanic population.

Temporal trends in the risk of developing multiple primary cancers: a systematic review. BMC Cancer 2016; 16:849. [PMID: 27814758 PMCID: PMC5097442 DOI: 10.1186/s12885-016-2876-y] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2016] [Accepted: 10/24/2016] [Indexed: 01/21/2023] Open
Abstract
Background Cancer survivors are at risk of developing second and subsequent primary cancers, referred to as multiple primary cancers (MPCs). It is not clear whether the risk of MPCs has increased over recent decades, but increasing use of radiological imaging and potentially harmful effects of certain cancer treatments raise this possibility. A systematic review was undertaken to assess whether there has been a temporal change in the risk of developing MPCs. Methods A systematic search to identify population-based studies of MPCs was performed in Medline/PubMed and Embase databases from inception to August 2016. Included studies were those reporting risk of MPCs for all sites combined following a first cancer at any site or a specific site, using standard incidence ratios (SIRs) or equivalent, and with analysis stratified by calendar years. Results We identified 28 articles eligible for inclusion, comprising 26 population-based studies and two monographs. MPC incidence was reported in nearly 6.5 million cancer survivors. For all first cancer sites combined, a higher rate of MPCs was reported in more recent than earlier calendar periods in four of the six relevant studies. The SIRs ranged from 1.14 for a first cancer diagnosis in the early 1980s to 1.21–1.46 in the late 1990s in the USA and Australia. Two studies from Italy and France showed no significant difference in SIRs across time periods 1978–2010 and 1989–2004. The remaining 22 studies reported various temporal trends in the risk of developing MPCs after a first cancer at a specific site, but most showed little change. Conclusion Overall, the risk of developing MPCs appears to have increased since the 1980s when considering studies of all primary cancer sites combined from the USA and Australia but not from Europe. With the introduction of more routine nuclear medical imaging over the last 15 years, more studies are needed to confirm recent trends of MPC risk in adult cancer survivors.

Abstract
The objective of this study was to investigate the effectiveness of using decision support instruments (DSI) to assist African-American (AA) men in making a prostate cancer (CaP) screening decision. This nonrandomized pretest-posttest comparison study assessed two DSI that were either culturally tailored or culturally nonspecific. CaP knowledge, intention to screen, and preferences were assessed before and after exposure to DSI using a convenience sample of 120 AA men aged 40 years and above. Participants interested in screening were referred to healthcare providers through a community-based patient navigator to obtain prostate-specific antigen (PSA) testing. We followed up 3 months after to determine if participants screened for CaP. CaP knowledge increased following exposure to both DSI in equivalent proportions. While similar proportions of men ultimately intended on having a PSA test following both DSI, bivariate analysis revealed that the culturally tailored DSI demonstrated a statistically significant increase in intention to screen. Participants' degree of certainty in their decision-making process with regard to CaP screening increased following the culturally tailored DSI (p < .001). The majority of participants planned on discussing CaP screening with a healthcare provider upon completion of the study. Barbershop-based health education can change the knowledge, preferences, intentions, and behaviors of this at-risk population. At 3 months follow-up, half (n = 58) of the participants underwent PSA testing, which led to the diagnosis of CaP in one participant. Community-led interventions for CaP, such as cluster-randomized designs in barbershops, are needed to better assess the efficacy of DSI in community settings.

Abstract
BACKGROUND The burden of breast and cervical cancer is changing over time in developing countries. Regular screening is very important for early detection and treatment. In this study, we assessed inequalities in breast and cervical cancer screening rates in women according to household wealth status, and analyzed the potential predictors associated with a low cancer screening rate in Jordan. MATERIALS AND METHODS A nationwide population- based cross-sectional survey collected information on different variables at the national level. All ever-married women (the phrase is used throughout the text to refer to women who had ever married) aged 15-49 years were included in the survey. Analysis of breast self-examination (BSE) and clinical breast examination (CBE) at least once in the previous year was carried out in 11,068 women, while lifetime Pap-smear testing was carried out in 8,333 women, aged 20-49 years. RESULTS Over 39% and 19% of ever-married Jordanian women reported having undergone a breast examination during the previous year and Pap smear examination at least once in their lifetime, respectively. The rate of BSE in the previous year was 31.5%, that of CBE in the previous year was 19.3%, and that of Pap smear examination at least once in life was 25.5%. The adjusted OR was higher for performing BSE (aOR 1.22, 95% CI 1.04-1.43), undergoing CBE (aOR 1.31, 95% CI 1.08-1.60) and undergoing Pap smear examination (aOR 2.38, 95% CI 1.92-2.93) among women in the highest wealth-index quintile as compared to those in the lowest quintile. The concentration index was 0.11 for BSE, 0.01 for CBE, and 0.27 for Pap smear examination. Women in their twenties, living in rural or the southern region of Jordan, with an elementary school education or less, who listened to the radio or read the newspaper not more than a few times a year, and nulliparous women were less likely to undergo breast and cervical cancer screening. CONCLUSIONS The rates of breast and cervical cancer screening are low in Jordan. Reducing the sociodemographic and economic inequalities in breast and cervical cancer screenings requires concerted outreach activities for women living under socially deprived conditions.

Abstract
In this article, we examine perceived breast cancer screening barriers and facilitative conditions for immigrant women from Mexico, Puerto Rico, Cuba, El Salvador, and South America ( N = 58). Focus groups conducted separately with women of each ancestry were analyzed using grounded theory methods. Identified barriers comprise secrecy, lack of information, embarrassment, fear, and distrust of health care providers. Perceived facilitative conditions include knowing the importance of early detection and noticing a symptom. We compare and contrast findings across ancestries and discuss how psychosocial and cultural factors could be better integrated into early detection programs. The women's high screening rates also suggest that breast cancer screening can be facilitated in this population by addressing institutional factors (e.g., access to health care, transportation).

Abstract
INTRODUCTION Our study sought to characterize the presentation, local management and outcomes of invasive cervical cancer with regard to patient insurance status. METHODS We queried the NCI-SEER database for invasive cervical cancer cases in patients aged 18-64 from 2007 to 2011. We analyzed clinical and socioeconomic data with regard insurance status (insured, Medicaid, or uninsured). We tested for associations between patient insurance status and treatment with definitive surgery for FIGO IA2-IB1 patients, and treatment with suboptimal radiation therapy (RT) for FIGO IB2-IVA patients (other than combination external beam and brachytherapy). We evaluated overall and cause specific survival according to insurance status. RESULTS 11,714 cases were analyzed: 60% insured, 31% Medicaid, and 9% uninsured. FIGO III/IV stage at presentation was more frequent with Medicaid (40%) and uninsured (42%) compared to insured patients (28%) (p<0.001). For FIGO IA2-IB1 patients, receipt of definitive surgery was inversely associated with uninsured status (OR [95%CI]=0.65 [0.47-0.90], p<0.001) in univariable analysis; however the relationship lost significance after multivariable adjustment. For FIGO IB2-IVA patients, the use of suboptimal RT was associated with uninsured status (OR [95%CI]=1.33 [1.07-1.65], p=0.011) in adjusted analyses. Among all patients, overall mortality was increased with Medicaid (HR [95%CI]=1.16 [1.05-1.28], p=0.003) and uninsured status (HR [95%CI]=1.17 [1.01-1.34], p=0.031) in multivariable analysis. Cancer specific mortality survival trended towards significance in multivariable analyses for both Medicaid (HR [95%CI]=1.11 [1.00-1.24] and uninsured status (HR [95%CI]=1.14 [0.98-1.33]). CONCLUSIONS Disparities in cervical cancer treatment with regard to insurance status are apparent in a recent cohort of American patients. Later stage at presentation and differences in management partially account for the inferior prognostic outcomes associated with Medicaid and uninsured status.

Abstract
BACKGROUND Human papillomavirus (HPV) vaccine should reduce cervical dysplasia before cervical cancer. However, dysplasia diagnosis is screening-dependent. Accurate screening estimates are needed. PURPOSE To estimate the percentage of women in a geographic population that has had cervical cancer screening. METHODS We analyzed claims data for (Papanicolau) Pap tests from 2008-2012 to estimate the percentage of insured women aged 18-39 years screened. We estimated screening in uninsured women by dividing the percentage of insured Behavioral Risk Factor Surveillance Survey respondents reporting previous-year testing by the percentage of uninsured respondents reporting previous-year testing, and multiplying this ratio by claims-based estimates of insured women with previous-year screening. We calculated a simple weighted average of the two estimates to estimate overall screening percentage. We estimated credible intervals using Monte-Carlo simulations. RESULTS During 2008-2012, an annual average of 29.6% of women aged 18-39 years were screened. Screening increased from 2008 to 2009 in all age groups. During 2009-2012, the screening percentages decreased for all groups, but declined most in women aged 18-20 years, from 21.5% to 5.4%. Within age groups, compared to 2009, credible intervals did not overlap during 2011 (except age group 21-29 years) and 2012, and credible intervals in the 18-20 year group did not overlap with older groups in any year. CONCLUSIONS This introduces a novel method to estimate population-level cervical cancer screening. Overall, percentage of women screened in Portland, Oregon fell following changes in screening recommendations released in 2009 and later modified in 2012.

Colorectal Cancer Screening and State Health Insurance Mandates. HEALTH ECONOMICS 2016; 25:178-191.

Abstract
Colorectal cancer (CRC) is the third most deadly cancer in the USA. CRC screening is the most effective way to prevent CRC death, but compliance with recommended screenings is very low. In this study, we investigate whether CRC screening behavior changed under state mandated private insurance coverage of CRC screening in a sample of insured adults from the 1997 to 2008 Behavioral Risk Factor Surveillance Survey (BRFSS). We present difference-in-difference-in-differences (DDD) estimates that compare insured individuals age 51 to 64 to Medicare age-eligible individuals (ages 66 to 75) in mandate and non-mandate states over time. Our DDD estimates suggest endoscopic screening among men increased by 2 to 3 percentage points under mandated coverage among 51 to 64 year olds relative to their Medicare age-eligible counterparts. We find no clear evidence of changes in screening behavior among women. DD estimates suggest no evidence of a mandate effect on either type of CRC screening for men or women.

Abstract
Cancer is the leading cause of death among Hispanics/Latinos, who represent the largest racial/ethnic minority group in the United States, accounting for 17.4% (55.4 million/318 million) of the total US population in 2014. Every 3 years, the American Cancer Society reports on cancer statistics for Hispanics based on incidence data from the National Cancer Institute, the Centers for Disease Control and Prevention, and the North American Association of Central Cancer Registries and mortality data from the National Center for Health Statistics. Among Hispanics in 2015, there will be an estimated 125,900 new cancer cases diagnosed and 37,800 cancer deaths. For all cancers combined, Hispanics have 20% lower incidence rates and 30% lower death rates compared with non-Hispanic whites (NHWs); however, death rates are slightly higher among Hispanics during adolescence (aged 15-19 years). Hispanic cancer rates vary by country of origin and are generally lowest in Mexicans, with the exception of infection-associated cancers. Liver cancer incidence rates in Hispanic men, which are twice those in NHW men, doubled from 1992 to 2012; however, rates in men aged younger than 50 years declined by 43% since 2003, perhaps a bellwether of future trends for this highly fatal cancer. Variations in cancer risk between Hispanics and NHWs, as well as between subpopulations, are driven by differences in exposure to cancer-causing infectious agents, rates of screening, and lifestyle patterns. Strategies for reducing cancer risk in Hispanic populations include increasing the uptake of preventive services (e.g., screening and vaccination) and targeted interventions to reduce obesity, tobacco use, and alcohol consumption.

Abstract
BACKGROUND Prostate cancer is one of the most common cancers affecting men globally, constituting the sixth leading cause of cancer related death in males, and the eleventh leading cause of death from cancer in all age groups. In Jordan, prostate cancer is the third most common cancer in the male population, accounting for one third (6.2%) of cancer related deaths and in 2010 alone, 218 (9.4%) new cases were identified. OBJECTIVE To assess the effectiveness of different health education interventions aimed at enhancing knowledge, beliefs and intention to screen for prostate cancer. MATERIALS AND METHODS A literature search from January 2000 to April 2015 was conducted using the key words "prostate disease," "educational program," "knowledge," "prostate cancer," "demographic factors and prostate cancer," "knowledge and prostate cancer," "education for patients with prostate cancer," "factors that affect intention to screen," "knowledge, beliefs, and intention to screen for prostate cancer," "impact of prostate educational program on beliefs," and "impact of educational program on intention to screen." RESULTS Majority of studies reviewed indicated that men had low levels of knowledge regarding prostate cancer, and mild to moderate beliefs with good intention to screen for prostate cancer. CONCLUSIONS Most studies indicated that men's knowledge levels about prostate cancer were poor and they had mild to moderate beliefs and intentions to screen for prostate cancer. Therefore, development of an assessment strategy based on the Health Belief Model seems essential. An effectively designed and implemented educational program can help identify the needs and priorities of the target population.

Potential Biases Introduced by Conflating Screening and Diagnostic Testing in Colorectal Cancer Screening Surveillance. Cancer Epidemiol Biomarkers Prev 2015; 24:1850-4.

Abstract
BACKGROUND Screening and postsymptomatic diagnostic testing are often conflated in cancer screening surveillance research. We examined the error in estimated colorectal cancer screening prevalence due to the conflation of screening and diagnostic testing. METHODS Using data from the 2008 National Health Interview Survey, we compared weighted prevalence estimates of the use of all testing (screening and diagnostic) and screening in at-risk adults and calculated the overestimation of screening prevalence across sociodemographic groups. RESULTS The population screening prevalence was overestimated by 23.3%, and the level of overestimation varied widely across sociodemographic groups (median, 22.6%; mean, 24.8%). The highest levels of overestimation were in non-Hispanic white females (27.4%), adults ages 50-54 years (32.0%), and those with the highest socioeconomic vulnerability [low educational attainment (31.3%), low poverty ratio (32.5%), no usual source of health care (54.4%), and not insured (51.6%); all P < 0.001]. CONCLUSIONS When the impetus for testing was not included, colorectal cancer screening prevalence was overestimated, and patterns of overestimation often aligned with social and economic vulnerability. These results are of concern to researchers who use survey data from the Behavioral Risk Factor Surveillance System (BRFSS) to assess cancer screening behaviors, as it is currently not designed to distinguish diagnostic testing from screening. IMPACT Surveillance research in cancer screening that does not consider the impetus for testing risks measurement error of screening prevalence, impeding progress toward improving population health. Ultimately, to craft relevant screening benchmarks and interventions, we must look beyond "what" and "when" and include "why."

Socioecological determinants of mammography screening in Mexican rural areas. INTERNATIONAL JOURNAL OF PHARMACEUTICAL AND HEALTHCARE MARKETING 2015.

Abstract
Purpose– The purpose of this paper is to determine which socioecological factors encourage rural women to participate in mammographies rather than avoiding taking the test.Design/methodology/approach– The study mainly uses data from the 2007 Rural Households Evaluation Survey (ENCEL-2007). These crossover data are analyzed using the framework proposed in the Spatial-Interaction Model of Mammography Use (SIMMU), through a three-level logistic regression model to examine the likelihood that a woman will choose to participate in a mammography.Findings– At the woman-household level, the completion of the Pap smear and the asset index is the strongest determinant of mammography participation. Obtaining preventive medicine services or being enrolled in the Popular Insurance System prevent women from undergoing screening. At the interpersonal level, the probability of screening use decreases with lower social coverage. At the intermediate level, availability of health centers is negatively related to the use of screening.Research limitations/implications– The study fails to take into account the fact that women’s propensity to have a mammography may vary over time relatively to life changes. Moreover, findings were restricted to women ages from 40 to 49 and limited due to the lack of published data or data quality issues.Practical implications– The results of this research can give health planners, policymakers and social marketers a platform for how to approach social change and promote the cancer screening health behavior through the marketing mix (price, place, promotion and product) in the design of their programs.Originality/value– In addition to be informative and persuasive with people to change their behavior, this paper also seeks to provide a direction for using commercial marketing tools through social marketing to “sell” the health behavior. Due to target population variation, this paper addresses the health behavior change strategy by audience segmentation, regarded as essential to successful health communication campaigns.

Abstract
OBJECTIVE The current study aimed to identify the barriers to participation among high-risk individuals in the UK Lung Cancer Screening (UKLS) pilot trial. SETTING The UKLS pilot trial is a randomised controlled trial of low-dose CT (LDCT) screening that has recruited high-risk people using a population approach in the Cambridge and Liverpool areas. PARTICIPANTS High-risk individuals aged 50-75 years were invited to participate in UKLS. Individuals were excluded if a LDCT scan was performed within the last year, if they were unable to provide consent, or if LDCT screening was unable to be carried out due to coexisting comorbidities. OUTCOME MEASURES Statistical associations between individual characteristics and UKLS uptake were examined using multivariable regression modelling. In those who completed a non-participation questionnaire (NPQ), thematic analysis of free-text data was undertaken to identify reasons for not taking part, with subsequent exploratory linkage of key themes to risk factors for non-uptake. RESULTS Comparative data were available from 4061 high-risk individuals who consented to participate in the trial and 2756 who declined participation. Of those declining participation, 748 (27.1%) completed a NPQ. Factors associated with non-uptake included: female gender (OR=0.64, p<0.001), older age (OR=0.73, p<0.001), current smoking (OR=0.70, p<0.001), lower socioeconomic group (OR=0.56, p<0.001) and higher affective risk perception (OR=0.52, p<0.001). Among non-participants who provided a reason, two main themes emerged reflecting practical and emotional barriers. Smokers were more likely to report emotional barriers to participation. CONCLUSIONS A profile of risk factors for non-participation in lung screening has emerged, with underlying reasons largely relating to practical and emotional barriers. Strategies for engaging high-risk, hard-to-reach groups are critical for the equitable uptake of a potential future lung cancer screening programme. TRIAL REGISTRATION NUMBER The UKLS trial was registered with the International Standard Randomised Controlled Trial Register under the reference 78513845.

Non-normal Screening Mammography Results, Lumpectomies, and Breast Cancer Reported by California Women, 2001-2009. Womens Health Issues 2015; 25:331-40. [PMID: 26070253 PMCID: PMC4500637 DOI: 10.1016/j.whi.2015.03.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2014] [Revised: 01/09/2015] [Accepted: 03/09/2015] [Indexed: 10/23/2022]
Abstract
BACKGROUND Although screening mammography may contribute to decreases in breast cancer mortality in a population, it may also increase the risk of false positives, anxiety, and unnecessary and costly medical procedures in individuals. We report trends in self-reported non-normal screening mammography results, lumpectomies, and breast cancer in a representative sample of California women. METHODS Data were obtained from the 2001, 2005, and 2009 cross-sectional California Health Interview Surveys (CHIS) and weighted to the California population. CHIS employed a multistage sampling design to administer telephone surveys in 6 languages. Our study sample was restricted to women 40 years and older who reported a screening mammogram in the past 2 years. Sample sizes were 13,974 in 2001, 12,069 in 2005, and 15,552 in 2009. Women reporting non-normal results were asked whether they had an operation to remove the lump and, if so, whether the lump was confirmed as malignant. FINDINGS Between 2001 and 2009, the percent of California women who reported having been diagnosed with breast cancer was relatively stable. For each of the three age groups studied, the percentage of non-normal mammography results increased and the percentages of lumpectomies decreased and, for every woman reporting a diagnosis of breast cancer, three women reported a lumpectomy that turned out not to be cancer. This ratio was greater for younger women and less for older women. CONCLUSIONS Despite relatively constant rates of breast cancer diagnosis from 2001 to 2009, the percentage of non-normal mammography results increased and lumpectomies declined.

Using three years (2006, 2008, 2010) of nationally representative data from the Behavioral Risk Factor Surveillance System, I assessed the socioeconomic status (SES) gradient for odds of receiving a mammogram in the past two years and a Pap test in the past three years among White, Black, Hispanic, and Asian women living in the U.S. Mammogram and Pap test utilization were less likely among low-SES women. However, women of color experience less benefit than Whites from increasing SES for both screenings; as income and education increased, White women experienced more pronounced increases in the likelihood of being screened than did women of color. In what might be referred to as paradoxical returns, Asian women actually experienced a decline in the likelihood of obtaining a recent Pap test at higher levels of education. My findings suggest that women of color differ from Whites in the extent to which increasing socioeconomic resources is associated with increasing cancer screening utilization.

Cost of services provided by the National Breast and Cervical Cancer Early Detection Program. Cancer 2014; 120 Suppl 16:2604-11. [PMID: 25099904 DOI: 10.1002/cncr.28816] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2014] [Accepted: 03/06/2014] [Indexed: 12/25/2022]
Abstract
BACKGROUND The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) is the largest cancer screening program for low-income women in the United States. This study updates previous estimates of the costs of delivering preventive cancer screening services in the NBCCEDP. METHODS We developed a standardized web-based cost-assessment tool to collect annual activity-based cost data on screening for breast and cervical cancer in the NBCCEDP. Data were collected from 63 of the 66 programs that received funding from the Centers for Disease Control and Prevention during the 2006/2007 fiscal year. We used these data to calculate costs of delivering preventive public health services in the program. RESULTS We estimated the total cost of all NBCCEDP services to be $296 (standard deviation [SD], $123) per woman served (including the estimated value of in-kind donations, which constituted approximately 15% of this total estimated cost). The estimated cost of screening and diagnostic services was $145 (SD, $38) per women served, which represented 57.7% of the total cost excluding the value of in-kind donations. Including the value of in-kind donations, the weighted mean cost of screening a woman for breast cancer was $110 with an office visit and $88 without, the weighted mean cost of a diagnostic procedure was $401, and the weighted mean cost per breast cancer detected was $35,480. For cervical cancer, the corresponding cost estimates were $61, $21, $415, and $18,995, respectively. CONCLUSIONS These NBCCEDP cost estimates may help policy makers in planning and implementing future costs for various potential changes to the program.

Implementation intentions and colorectal screening: a randomized trial in safety-net clinics. Am J Prev Med 2014; 47:703-14. [PMID: 25455115 PMCID: PMC4311575 DOI: 10.1016/j.amepre.2014.08.005] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2013] [Revised: 07/08/2014] [Accepted: 08/05/2014] [Indexed: 02/06/2023]
Abstract
CONTEXT Low-income and racial/ethnic minority populations experience disproportionate colorectal cancer (CRC) burden and poorer survival. Novel behavioral strategies are needed to improve screening rates in these groups. BACKGROUND The study aimed to test a theoretically based "implementation intentions" intervention for improving CRC screening among unscreened adults in urban safety-net clinics. DESIGN Randomized controlled trial. SETTING/PARTICIPANTS Adults (N=470) aged ≥50 years, due for CRC screening, from urban safety-net clinics were recruited. INTERVENTION The intervention (conducted in 2009-2011) was delivered via touchscreen computers that tailored informational messages to decisional stage and screening barriers. The computer then randomized participants to generic health information on diet and exercise (Comparison group) or "implementation intentions" questions and planning (Experimental group) specific to the CRC screening test chosen (fecal immunochemical test or colonoscopy). MAIN OUTCOME MEASURES The primary study outcome was completion of CRC screening at 26 weeks based on test reports (analysis conducted in 2012-2013). RESULTS The study population had a mean age of 57 years and was 42% non-Hispanic African American, 28% non-Hispanic white, and 27% Hispanic. Those receiving the implementation intentions-based intervention had higher odds (AOR=1.83, 95% CI=1.23, 2.73) of completing CRC screening than the Comparison group. Those with higher self-efficacy for screening (AOR=1.57, 95% CI=1.03, 2.39), history of asthma (AOR=2.20, 95% CI=1.26, 3.84), no history of diabetes (AOR=1.86, 95% CI=1.21, 2.86), and reporting they had never heard that "cutting on cancer" makes it spread (AOR=1.78, 95% CI=1.16, 2.72) were more likely to complete CRC screening. CONCLUSIONS The results of this study suggest that programs incorporating an implementation intentions approach can contribute to successful completion of CRC screening even among very low-income and diverse primary care populations. Future initiatives to reduce CRC incidence and mortality disparities may be able to employ implementation intentions in large-scale efforts to encourage screening and prevention behaviors.

Male Role Norms, Knowledge, Attitudes, and Perceptions of Colorectal Cancer Screening among Young Adult African American Men. Front Public Health 2014; 2:252. [PMID: 25506049 PMCID: PMC4245902 DOI: 10.3389/fpubh.2014.00252] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2014] [Accepted: 11/09/2014] [Indexed: 11/23/2022] Open
Abstract
Racial disparities in health among African American men (AAM) in the United States are extensive. In contrast to their White counterparts, AAM have more illnesses and die younger. AAM have colorectal cancer (CRC) incidence and mortality rates 25% and 50% higher, respectively, than White men. Due to CRC's younger age at presentation and high incidence among AAM, CRC screening (CRCS) is warranted at the age of 45 rather than 50, but little is known about younger AAM's views of CRCS. Employing survey design, the purpose of the study was to describe the male role norms (MRN), knowledge, attitudes, perceived subjective norms, and perceived barriers associated with screening for CRC among a non-random sample of 157 young adult AAM (ages 19-45). Sixty-seven percent of the study sample received a passing knowledge score (85% or better), yet no significant differences were found among the three educational levels (i.e., low, medium, high). More negative attitudes toward CRCS correlated with the participants' strong perceptions of barriers, but no extremely negative or positive MRN and perceived subjective norms were found. The factors significantly associated with attitudes were family history of cancer (unsure), work status, and perceived barriers. Findings from this study provide a solid basis for developing structured health education interventions that address the salient factors shaping young adult AAM's view of CRC and early detection screening behaviors.

Abstract
BACKGROUND Most developing countries have been unable to implement well-organized health care systems, especially comprehensive Pap smear screening-based programs. One of the reasons for this is regional differences in medical services, and a low-cost portable cervical screening system is necessary. To improve regional discrepancies in cervical screening systems, we investigated the usefulness and acceptability of cervical self- sampling by liquid-based cytology (LBC) for 290 volunteers in the Lao PDR. MATERIALS AND METHODS Following health education with comprehensive documents, cervical self-sampling kits by LBC were distributed in three provincial, district, and village areas to a total of 290 volunteers, who were asked to take cytology samples by themselves. Subsequently, the acceptability of self-sampling was evaluated using a questionnaire. RESULTS The documents were well understood in all three regions. Regarding the acceptability of self-sampling, the selections for subsequent screening were 62% self-sampling, 36% gynecologist-sampling, 1% either method, and 1% other methods. The acceptability rates were higher in the district and the village than in the province. For the relationship between acceptability and pregnancy, the self-sampling selection rate was higher in the pregnancy-experienced group (75%) than in the pregnancy-inexperienced group (60%). For the relationship between selection of self-sampling and experience of screening, the self-sampling selection rate was higher in the screening-inexperienced group (62%) than in the screening-experienced group (52%). CONCLUSIONS Our data show that this new way forward, involving a combination of self-sampling and LBC, is highly acceptable regardless of age, educational background, and residence in rural areas in a developing country.

Abstract
OBJECTIVES Screening is useful in reducing cancer incidence and mortality. People with severe mental illness (PSMI) are vulnerable to cancer as they are exposed to higher levels of cancer risks. Little is known about PSMI's cancer screening behavior and associated factors. The present study examined the utilization of breast, cervical, prostate, and colorectal cancer screening among PSMI in Hong Kong and to identify factors associated with their screening behaviors. METHOD 591 PSMI from community mental health services completed a cross-sectional survey. RESULTS The percentage of cancer screening behavior among those who met the criteria for particular screening recommendation was as follows: 20.8% for mammography; 36.5% for clinical breast examination (CBE); 40.5% for pap-smear test; 12.8% for prostate examination; and 21.6% for colorectal cancer screening. Results from logistic regression analyses showed that marital status was a significant factor for mammography, CBE, and pap-smear test; belief that cancer can be healed if found early was a significant factor for pap-smear test and colorectal screening; belief that one can have cancer without having symptoms was a significant factor for CBE and pap-smear test; belief that one will have a higher risk if a family member has had cancer was a significant factor for CBE; and self-efficacy was a significant factor for CBE and pap-smear test behavior. CONCLUSIONS Cancer screening utilization among PSMI in Hong Kong is low. Beliefs about cancer and self-efficacy are associated with cancer screening behavior. Health care professionals should improve the knowledge and remove the misconceptions about cancer among PSMI; self-efficacy should also be promoted.

Disparities in cervical cancer mortality rates as determined by the longitudinal hyperbolastic mixed-effects type II model. PLoS One 2014; 9:e107242. [PMID: 25226583 PMCID: PMC4167327 DOI: 10.1371/journal.pone.0107242] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2014] [Accepted: 08/01/2014] [Indexed: 12/29/2022] Open
Abstract
Background The main purpose of this study was to model and analyze the dynamics of cervical cancer mortality rates for African American (Black) and White women residing in 13 states located in the eastern half of the United States of America from 1975 through 2010. Methods The cervical cancer mortality rates of the Surveillance, Epidemiology, and End Results (SEER) were used to model and analyze the dynamics of cervical cancer mortality. A longitudinal hyperbolastic mixed-effects type II model was used to model the cervical cancer mortality data and SAS PROC NLMIXED and Mathematica were utilized to perform the computations. Results Despite decreasing trends in cervical cancer mortality rates for both races, racial disparities in mortality rates still exist. In all 13 states, Black women had higher mortality rates at all times. The degree of disparities and pace of decline in mortality rates over time differed among these states. Determining the paces of decline over 36 years showed that Tennessee had the most rapid decline in cervical cancer mortality for Black women, and Mississippi had the most rapid decline for White Women. In contrast, slow declines in cervical cancer mortality were noted for Black women in Florida and for White women in Maryland. Conclusions In all 13 states, cervical cancer mortality rates for both racial groups have fallen. Disparities in the pace of decline in mortality rates in these states may be due to differences in the rates of screening for cervical cancers. Of note, the gap in cervical cancer mortality rates between Black women and White women is narrowing.

Abstract
BACKGROUND African Americans have the highest incidence and mortality from colorectal cancer (CRC). Despite guidelines to initiate screening with colonoscopy at age 45 in African Americans, the CRC incidence remains high in this group. OBJECTIVE To examine the rates and predictors of CRC screening uptake as well as time to screening in a population of African Americans and non-African Americans in a health care system that minimizes variations in insurance and access. DESIGN Retrospective cohort study. SETTING Greater Los Angeles Veterans Affairs (VA) Healthcare System. PATIENTS Random sample (N = 357) of patients eligible for initial CRC screening. MAIN OUTCOME MEASUREMENTS Uptake of any screening method; uptake of colonoscopy, in particular; predictors of screening; and time to screening in African Americans and non-African Americans. RESULTS The overall screening rate by any method was 50%. Adjusted rates for any screening were lower among African Americans than non-African Americans (42% vs 58%; odds ratio [OR] 0.49; 95% confidence interval [CI], 0.31-0.77). Colonoscopic screening was also lower in African Americans (11% vs 23%; adjusted OR 0.43; 95% CI, 0.24-0.77). In addition to race, homelessness, lower service connectedness, taking more prescription drugs, and not seeing a primary care provider within 2 years of screening eligibility predicted lower uptake of screening. Time to screening colonoscopy was longer in African Americans (adjusted hazard ratio 0.43; 95% CI, 0.25-0.75). LIMITATIONS The sample may not be generalizable. CONCLUSIONS We found marked disparities in CRC screening despite similar access to care across races. Despite current guidelines aimed at increasing CRC screening in African Americans, participation in screening remained low, and use of colonoscopy was infrequent.

Abstract
The Texas Breast and Cervical Cancer Services (BCCS) program was established to address the socioeconomic disparities in stage at diagnosis and outcomes among breast cancer patients. This study examines the impact of Texas BCCS on stage at diagnosis among low socioeconomic status (SES) breast cancer patients. This is a retrospective analysis of women aged 40-64 years who were screened and diagnosed with breast cancer through the Texas BCCS program (participants) as compared with similar women living in low-SES census tracts and diagnosed outside the program (comparison group) during 1995-2008. Incident cases among the participants were compared with the comparison group as well. Stage at diagnosis was also analyzed separately for the years 1995-2002 and 2003-2008 in order to estimate the effect of BCCS-related Medicaid expansion in 2002. Over the study period of 1995-2008, BCCS participants had a 1.23 (P value<0.0001) times higher odds, and BCCS incident cases had 40% (P value<0.0001) lower odds of advanced stage at diagnosis as compared with the comparison group. A statistically significant difference in stage at diagnosis between the participants and the comparison group only existed for the 2003-2008 (post-Medicaid) period (odds ratio: 1.39, P value<0.0001). Texas BCCS program acts as a source of diagnosis and treatment access to many suspected cancer cases, especially since the 2002 Medicaid expansion, leading to more advanced stage at diagnosis among the BCCS cases as compared with other low-SES cases. Significant expansion of the program to serve a higher proportion of the eligible population is needed to achieve its goals as a screening program.
