RESUMO

The National Comprehensive Cancer Control Program, a Centers for Disease Control and Prevention funded program, supports cancer coalitions across the United States (US) in efforts to prevent and control cancer including development of comprehensive cancer control (CCC) plans. CCC plans often focus health equity within their priorities, but it is unclear to what extent lesbian, gay, bisexual, transgender, queer/questioning, plus (LGBTQ+) populations are considered in CCC plans. We qualitatively examined to what extent LGBTQ+ populations were referenced in 64 U.S. state, jurisdiction, tribes, and tribal organization CCC plans. A total of 55% of CCC plans mentioned LGBTQ+ populations, however, only one in three CCC plans mentioned any kind of LGBTQ+ inequity or LGBTQ+ specific recommendations. Even fewer plans included mention of LGBTQ+ specific resources, organizations, or citations. At the same time almost three fourths of plans conflated sex and gender throughout their CCC plans. The findings of this study highlight the lack of prioritization of LGBTQ+ populations in CCC plans broadly while highlighting exemplar plans that can serve as a roadmap to more inclusive future CCC plans. Comprehensive cancer control plans can serve as a key policy and advocacy structure to promote a focus on LGBTQ+ cancer prevention and control.

RESUMO

Introduction: Sleep disruption affects biological processes that facilitate carcinogenesis. This retrospective cohort study used de-identified data from the Veterans Administration (VA) electronic medical record system to test the hypothesis that patients with diagnosed sleep disorders had an increased risk of prostate, breast, colorectal, or other cancers (1999-2010, N=663,869). This study builds upon existing evidence by examining whether patients with more severe or longer-duration diagnoses were at a greater risk of these cancers relative to those with a less severe or shorter duration sleep disorder. Methods: Incident cancer cases were identified in the VA Tumor Registry and sleep disorders were defined by International Classification of Sleep Disorder codes. Analyses were performed using extended Cox regression with sleep disorder diagnosis as a time-varying covariate. Results: Sleep disorders were present among 56,055 eligible patients (8% of the study population); sleep apnea (46%) and insomnia (40%) were the most common diagnoses. There were 18,181 cancer diagnoses (41% prostate, 12% colorectal, 1% female breast, 46% other). The hazard ratio (HR) for a cancer diagnosis was 1.45 (95% confidence interval [CI]: 1.37, 1.54) among those with any sleep disorder, after adjustment for age, sex, state of residence, and marital status. Risks increased with increasing sleep disorder duration (short [<1-2 years] HR: 1.04 [CI: 1.03-1.06], medium [>2-5 years] 1.23 [1.16-1.32]; long [>5-12 years] 1.52 [1.34-1.73]). Risks also increased with increasing sleep disorder severity using cumulative sleep disorder treatments as a surrogate exposure; African Americans with more severe disorders had greater risks relative to those with fewer treatments and other race groups. Results among patients with only sleep apnea, insomnia, or another sleep disorder were similar to those for all sleep disorders combined. Discussion: The findings are consistent with other studies indicating that sleep disruption is a cancer risk factor. Optimal sleep and appropriate sleep disorder management are modifiable risk factors that may facilitate cancer prevention.

RESUMO

BACKGROUND: Stigma is a formidable burden for survivors of lung cancer that can reduce the quality of life (QOL), resulting in physical, social and psychological challenges. This study investigates associations between stigma and depression, QOL and demographic and health-related characteristics, including race. DESIGN: An adapted conceptual model derived from the Cataldo Lung Cancer Stigma Scale guided this descriptive correlation study assessing stigma in African American and Caucasian survivors of lung cancer. Self-reported, written surveys measuring depression, QOL, lung cancer stigma and demographics were administered. Statistical analysis was conducted to assess associations between stigma and depression, stigma and QOL and stigma and race, while adjusting for demographic characteristics. RESULTS: Participants (N = 56) included 30 Caucasian and 26 African American survivors of lung cancer recruited from a cancer registry of an American College of Surgeons-accredited programme, a survivors' support club and an ambulatory oncology practice in the southeastern United States. Statistical analysis yielded (1) a significant moderate positive association between depression and lung cancer stigma; (2) a significant moderate negative association between QOL and lung cancer stigma; and (3) significant relationships between race and lung cancer stigma, specifically higher degree of stigma among African Americans compared to Caucasians. CONCLUSION: Stigma affects many aspects of survivors' lives. Healthcare professionals need to consider how health-related stigma may further complicate the physical burdens, psychological distresses and social challenges that accompany the disease, especially among African American survivors. Additional enquiry and interventions are needed to assist with mitigating the negative effects of stigma on survivors and their family members and friends. PATIENT OR PUBLIC CONTRIBUTION: Fifty-six survivors of lung cancer participated in this descriptivecorrelation study. They completed written surveys measuring depression, QOL, and lung cancer stigma, plus an investigator-developed demographic information form.

RESUMO

PURPOSE: Persistent breast cancer disparities, particularly geographic disparities, may be explained by diagnostic practice patterns such as utilization of needle biopsy, a National Quality Forum-endorsed quality metric for breast cancer diagnosis. Our objective was to assess the relationship between patient- and facility-level factors and needle biopsy receipt among women with non-metastatic breast cancer in the United States. METHODS: We examined characteristics of women diagnosed with breast cancer between 2004 and 2015 in the National Cancer Database. We assessed the relationship between patient- (e.g., race/ethnicity, stage, age, rurality) and facility-level (e.g., facility type, breast cancer case volume) factors with needle biopsy utilization via a mixed effects logistic regression model controlling for clustering by facility. RESULTS: In our cohort of 992,209 patients, 82.96% received needle biopsy. In adjusted models, the odds of needle biopsy receipt were higher for Hispanic (OR 1.04, Confidence Interval 1.01-1.08) and Medicaid patients (OR 1.04, CI 1.02-1.08), and for patients receiving care at Integrated Network Cancer Programs (OR 1.21, CI 1.02-1.43). Odds of needle biopsy receipt were lower for non-metropolitan patients (OR 0.93, CI 0.90-0.96), patients with cancer stage 0 or I (at least OR 0.89, CI 0.86-0.91), patients with comorbidities (OR 0.93, CI 0.91-0.94), and for patients receiving care at Community Cancer Programs (OR 0.84, CI 0.74-0.96). CONCLUSION: This study suggests a need to account for sociodemographic factors including rurality as predictors of utilization of evidence-based diagnostic testing, such as needle biopsy. Addressing inequities in breast cancer diagnosis quality may help improve breast cancer outcomes in underserved patients.

RESUMO

BACKGROUND: Lack of adherence to tyrosine kinase inhibitors (TKIs) is a significant problem resulting in incomplete cytogenetic response and increased mortality in patients with chronic myeloid leukemia (CML). Few studies have been conducted on interventions to improve adherence. The authors conducted a systematic review to explore studies that examined the impact of strategies to improve TKI adherence among individuals with CML. METHODS: The first 2 authors completed a systematic literature review according to the guidelines in Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA). Studies (n=2633) conducted between 1980 and 2019 were identified through 3 databases and examined for inclusion/exclusion criteria. RESULTS: Fourteen studies were identified which met the eligibility criteria. The studies only examined adherence to imatinib, dasatinib, or nilotinib. Ten of the 14 used large data sets (commercial health insurance plans or Surveillance Epidemiology and End Results [SEER] data) for analysis. The majority of the studies used a cohort design. Adherence was defined and measured in a variety of ways with most studies using 80% or higher as adequate adherence. Strategies not focused on health care costs used a multidisciplinary team approach. CONCLUSION: Development of evidence to improve treatment adherence to TKIs for CML have relied on large data sets rather than prospective trials. Current studies lack patient focused interventions.

RESUMO

OBJECTIVE: To examine the role of driving time to cancer care facilities on days to cancer treatment initiation and cause-specific survival for cervical cancer patients. METHODS: A retrospective cohort analysis of patients diagnosed with invasive cervical cancer during 2001-2016, using South Carolina Central Cancer Registry data linked to vital records. Kaplan-Meier survival curves and Cox proportional hazards models were used to examine the association of driving times to both a patient's nearest and actual cancer treatment initiation facility with cause-specific survival and time to treatment initiation. RESULTS: Of 2518 eligible patients, median cause-specific survival was 49 months (interquartile, 17-116) and time to cancer treatment initiation was 21 days (interquartile, 0-40). Compared to patients living within 15 min of the nearest cancer provider, those living more than 30 min away were less likely to receive initial treatment at teaching hospitals, Joint Commission accredited facilities, and/or Commission on Cancer accredited facilities. After controlling for patient, clinical, and provider characteristics, no significant associations existed between driving times to the nearest cancer provider and survival/time to treatment. When examining driving times to treatment initiation (rather than simply nearest) provider, patients who traveled farther than 30 min to their actual providers had delayed initiation of cancer treatment (hazard ratio, 0.81; 95% confidence interval, 0.73-0.90), including surgery (0.82; 95% CI, 0.72-0.92) and radiotherapy (0.82, 95% CI, 0.72-0.94). Traveling farther than 30 min to the first treating provider was not associated with worse cause-specific survival. CONCLUSIONS: For cervical cancer patients, driving time to chosen treatment providers, but not to the nearest cancer care provider, was associated with prolonged time to treatment initiation. Neither was associated with survival.

RESUMO

BACKGROUND: Persistent rural-urban disparities for colorectal and cervical cancers raise concerns regarding access to treatment providers. To the authors knowledge, little is known regarding rural-urban differences in residential proximity to cancer specialists. METHODS: Using the 2018 Physician Compare data concerning physician practice locations and the 2012 to 2016 American Community Survey, the current study estimated the driving distance from each residential zip code tabulation area (ZCTA) centroid to the nearest cancer provider of the following medical specialties involved in treating patients with colorectal and cervical cancer: medical oncology, radiation oncology, surgical oncology, general surgery, gynecological oncology, and colorectal surgery. Using population-weighted multivariable logistic regression, the authors analyzed the associations between ZCTA-level characteristics and driving distances >60 miles to each type of specialist. ZCTA-level residential rurality was defined using rural-urban commuting area codes. RESULTS: Nearly 1 in 5 rural Americans lives >60 miles from a medical oncologist. Rural-urban differences in travel distances to the nearest cancer care provider(s) increased substantially for cancer surgeons; greater than one-half of rural residents were required to travel 60 miles to reach a gynecological oncologist, compared with 8 miles for their urban counterparts. Individuals residing within ZCTAs with a higher poverty rate, those of American Indian/Alaska Native ethnicity, and/or were located in the South and West regions were more likely than their counterparts to be >60 miles away from any of the aforementioned providers. CONCLUSIONS: The substantial travel distances required for rural, low-income residents to reach a cancer specialist should prompt a policy action to increase access to specialized cancer care for millions of rural residents.

RESUMO

PROBLEM IDENTIFICATION: Lung cancer survivors face many challenges that affect their quality of life and survival. A growing concern is the layered effect of stigma related to cigarette smoking and the perceived life-threatening diagnosis of lung cancer. This experience may affect lung cancer survivors' physical, psychological, and social well-being, negatively influencing their quality of life. LITERATURE SEARCH: CINAHL®, PubMed®, PsycINFO®, and Web of Science were searched from January 2000 through August 2017, using combinations of four keywords. DATA EVALUATION: Extracted data included research aims, design, method, analytical approach, sample size, gender, ethnicity/race, setting, stigma measure, smoking status, and major results. SYNTHESIS: Of 163 studies initially identified, 30 (19 quantitative, 8 qualitative, 2 theoretical reviews, and 1 mixed method) were included. Quantitative studies were analyzed by statistical significance and relevant findings. Thematic analysis was used to evaluate qualitative studies. IMPLICATIONS FOR RESEARCH: Future research should focus on the development and testing of tailored and multilevel interventions to support the management of stigma and lessen the negative impact it has on quality of life, with special considerations for vulnerable subpopulations.

RESUMO

PURPOSE: The purpose of this study was to examine rural-urban differences in utilization and expenditures in the last 6 months of life for patients with breast, lung, or colorectal cancer. METHODS: The study used a 5% sample of the 2013 Medicare Research Identifiable Files to study utilization and expenditures for beneficiaries with breast, lung, or colorectal cancer during the last 6 months before death (n = 6,214). End of life expenditures were calculated as the sum of total Medicare expenditures for inpatient, outpatient, physician, home health, hospice, and skilled nursing facility costs during the last 6 months of life. FINDINGS: For each type of cancer, total Medicare expenditures in the last 6 months of life were lower for rural decedents compared to their urban counterparts. During the last 6 months of life, median Medicare expenditures were lower for rural decedents for breast cancer ($21,839 vs $25,698), lung cancer ($22,814 vs $27,635), and colorectal cancer ($24,156 vs $28,035; all differences significant at P < .05). In adjusted models, care for rural decedents was less costly than urban decedents for breast, lung, and colorectal cancer, respectively. CONCLUSIONS: Our findings indicate that Medicare expenditures are lower for rural beneficiaries with each type of cancer than urban beneficiaries, even after adjusting for age, gender, race, dual eligibility, region, chronic conditions, and type of service utilization. The findings from this study can be useful for policymakers in developing programs and resource allocation decisions that impact rural beneficiaries.

RESUMO

OBJECTIVES: Non-small-cell lung cancer (NSCLC) patient survival depends on a number of factors, including early diagnosis and initiation of treatment. Standard treatment options for patients with NSCLC include surgery, radiation therapy, and chemotherapy. The objective of this study was to evaluate the impact that the initiation of timely treatment has on patient survival among a cohort of privately insured patients with NSCLC in South Carolina. METHODS: Data for the study were retrospectively obtained from the South Carolina Central Cancer Registry and the state health plan Blue Cross and Blue Shield claims. Patients were diagnosed as having NSCLC between January 1, 2005 and December 31, 2010, were aged 18 years or older, and were covered under the state health plan for at least 1 year before diagnosis. The final study sample included 746 patients. Kaplan-Meier curves and Cox proportional hazard modeling were conducted to examine factors associated with survival, stratified by stage at diagnosis. RESULTS: The majority in the study cohort (80%) received timely (≤6 weeks) rather than untimely (>6 weeks) care (20%). The mean survival time for patients receiving timely treatment by stage was 36.9, 27.1, and 12.4 months for localized, regional, and distant metastasis, respectively. The mean survival time for patients receiving untimely care by stage was 39.4, 33.8, and 25.2 months for localized, regional, and distant metastasis, respectively. Among patients with NSCLC in the distant metastasis stage, those receiving timely treatment experienced significantly decreased survival (hazard ratio 2.2) in comparison to those receiving untimely care. CONCLUSIONS: Initiation of treatment within 6 weeks is not associated with greater survival time across all stages of cancer (localized, regional, and distant metastasis). Additional research is needed to examine the impact of other treatment quality metrics on the survival of patients with NSCLC, different time thresholds for treatment initiation that may be more meaningful to survival among patients with NSCLC, and timely care among patients with NSCLC in other geographic areas and populations.

RESUMO

PURPOSE: A combination of the relatively high prevalence among gynecologic cancers, high survival, and the myriads of factors that negatively impact the quality of life (QoL) among endometrial cancer (EC) survivors underscores the potential benefits of meeting guideline physical activity (PA) guidelines of 150 minutes per week among EC survivors. The objective of the present systematic review was to collate and critically evaluate the currently available literature on the effects of PA on QoL among EC survivors. METHODS: Medline and Web of Science databases were searched for articles on EC, QoL, and PA. We also inspected bibliographies of relevant publications to identify related articles. Our search criteria yielded 70 studies, 7 of which met the inclusion criteria. RESULTS: Of the 7 studies examined, 2 of them were intervention studies, whereas 5 were cross-sectional studies. Meeting guideline PA was significantly associated with better QoL score in 4 of the 5 cross-sectional studies. CONCLUSIONS: Results from the cross-sectional studies suggest that EC survivors' inactivity is significantly correlated with poorer QoL. This correlation was worse among obese survivors compared with normal weight survivors. Endometrial cancer survivors may benefit from interventions that incorporate PA. More randomized intervention studies among EC survivors are needed to add to this body of evidence.

RESUMO

OBJECTIVES: Breast cancer is the most frequently diagnosed cancer among women and the second-leading cause of female cancer deaths in the United States. African Americans and other minorities in the United States experience lower survival rates and have a worse prognosis than European Americans despite European Americans having a much higher incidence of the disease. Adherence to breast cancer treatment-quality measures is limited, particularly when the data are stratified by race/ethnicity. METHODS: We aimed to examine breast cancer incidence and mortality trends in South Carolina by race and explore possible racial disparities in the quality of breast cancer treatment received in South Carolina. RESULTS: African Americans have high rates of mammography and clinical breast examination screenings yet suffer lower survival compared with European Americans. For most treatment-quality metrics, South Carolina fairs well in comparison to the United States as a whole; however, South Carolina hospitals overall lag behind South Carolina Commission on Cancer-accredited hospitals for all measured quality indicators, including needle biopsy utilization, breast-conserving surgeries, and timely use of radiation therapy. Accreditation may a play a major role in increasing the standard of care related to breast cancer diagnosis and treatment. CONCLUSIONS: These descriptive findings may provide significant insight for future interventions and policies aimed at eliminating racial/ethnic disparities in health outcomes. Further risk-reduction approaches are necessary to reduce minority group mortality rates, especially among African American women.

RESUMO

INTRODUCTION: A review was conducted to summarize the current evidence and gaps in the literature on geographic access to mammography and its relationship to breast cancer-related outcomes. METHODS: Ovid, Medline, and PubMed were searched for articles published between January 1, 2000, and April 1, 2013, using Medical Subject Headings and key terms representing geographic accessibility and breast cancer-related outcomes. Owing to a paucity of breast cancer treatment and mortality outcomes meeting the criteria (N = 6), outcomes were restricted to breast cancer screening and stage at diagnosis. Studies included one or more of the following types of geographic accessibility measures: capacity, density, distance, and travel time. Study findings were grouped by outcome and type of geographic measure. RESULTS: Twenty-one articles met the inclusion criteria. Fourteen articles included stage at diagnosis as an outcome, five included mammography use, and two included both. Geographic measures of mammography accessibility varied widely across studies. Findings also varied, but most articles found either increased geographic access to mammography associated with increased use and decreased late-stage at diagnosis or no association. CONCLUSION: The gaps and methodologic heterogeneity in the literature to date limit definitive conclusions about an underlying association between geographic mammography access and breast cancer-related outcomes. Future studies should focus on the development and application of more precise and consistent measures of geographic access to mammography.

RESUMO

OBJECTIVES: Although the National Lung Screening Trial (NLST) lauds the efficacy of low-dose computed tomography (LDCT) at reducing lung cancer mortality, it has not been widely used for population-based screening. By examining the availability of U.S. LDCT screening centers, and underlying rates of lung cancer incidence, mortality, and smoking prevalence, the need for additional centers may be determined. MATERIALS AND METHODS: Locations of 203 LDCT screening centers from the Lung Cancer Alliance Screening Centers of Excellence database, a list of active NLST and International Early Lung and Cardiac Action Program (I-ELCAP) screening centers, and an independently conducted survey of Society of Thoracic Radiology members were geocoded and mapped. County-level rates of lung cancer incidence, mortality, and smoking prevalence were also mapped and overlaid with the locations of the 203 LDCT screening centers. RESULTS AND CONCLUSIONS: Results showed the majority of LDCT screening centers were located in the counties with the highest quartiles of lung cancer incidence and mortality in the Northeast and East North Central states, but several high-risk states had no or few identified screening centers including Oklahoma, Nevada, Mississippi, and Arkansas. As guidelines are implemented and reimbursement for LDCT screening follows, equitable access to LDCT screening centers will become increasingly important, particularly in regions with high rates of lung cancer incidence and smoking prevalence.

RESUMO

Objective was to estimate race-specific proportions of gestational diabetes mellitus (GDM) attributable to overweight and obesity in South Carolina. South Carolina birth certificate and hospital discharge data were obtained from 2004 to 2006. Women who did not have type 2 diabetes mellitus before pregnancy were classified with GDM if a diagnosis was reported in at least one data source. Relative risks (RR) and 95 % confidence intervals were calculated using the log-binomial model. The modified Mokdad equation was used to calculate population attributable fractions for overweight body mass index (BMI: 25.0-29.9 kg/m(2)), obese (30.0-34.9 kg/m(2)), and extremely obese (≥35 kg/m(2)) women after adjusting for age, gestational weight gain, education, marital status, parity, tobacco use, pre-pregnancy hypertension, and pregnancy hypertension. Overall, the adjusted RR of GDM was 1.6, 2.3, and 2.9 times higher among the overweight, obese, and extremely obese women compared to normal-weight women in South Carolina. RR of GDM for extremely obese women was higher among White (3.1) and Hispanic (3.4) women than that for Black women (2.6). The fraction of GDM cases attributable to extreme obesity was 14.0 % among White, 18.1 % among Black, and 9.6 % among Hispanic women. The fraction of GDM cases attributable to obesity was about 12 % for all racial groups. Being overweight (BMI: 25.0-29.9) explained 8.8, 7.8, and 14.4 % of GDM cases among White, Black, and Hispanic women, respectively. Results indicate a significantly increased risk of GDM among overweight, obese, and extremely obese women. The strength of the association and the proportion of GDM cases explained by excessive weight categories vary by racial/ethnic group.

BACKGROUND: Chronic inflammation is linked to poor lifestyle behaviors and a variety of chronic diseases that are prevalent among African Americans, especially in the southeastern U.S. PURPOSE: The goal of the study was to test the effect of a community-based diet, physical activity, and stress reduction intervention conducted in 2009-2012 on reducing serum C-reactive protein (CRP) in overweight and obese African-American adults. METHODS: An RCT intervention was designed jointly by members of African-American churches and academic researchers. In late 2012, regression (i.e., mixed) models were fit that included both intention-to-treat and post hoc analyses conducted to identify important predictors of intervention success. Outcomes were assessed at 3 months and 1 year. RESULTS: At baseline, the 159 individuals who were recruited in 13 churches and had evaluable outcome data were, on average, obese (BMI=33.1 [±7.1]) and had a mean CRP level of 3.7 (±3.9) mg/L. Reductions were observed in waist-to-hip ratio at 3 months (2%, p=0.03) and 1 year (5%, p<0.01). In female participants attending ≥60% of intervention classes, there was a significant decrease in CRP at 3 months of 0.8 mg/L (p=0.05), but no change after 1 year. No differences were noted in BMI or interleukin-6. CONCLUSIONS: In overweight/obese, but otherwise "healthy," African-American church members with very high baseline CRP levels, this intervention produced significant reductions in CRP at 3 and 12 months, and in waist-to-hip ratio, which is an important anthropometric predictor of overall risk of inflammation and downstream health effects. TRIAL REGISTRATION: This study is registered at www.clinicaltrials.gov NCT01760902.

RESUMO

BACKGROUND: Prior studies suggest that weight satisfaction may preclude changes in behavior that lead to healthier weight among individuals who are overweight or obese. OBJECTIVE: To gain a better understanding of complex relationships between weight satisfaction, weight-related health behaviors, and health outcomes. DESIGN: Cross-sectional analysis of data from the Aerobics Center Longitudinal Study (ACLS). PARTICIPANTS: Large mixed-gender cohort of primarily white, middle-to-upper socioeconomic status (SES) adults with baseline examination between 1987 and 2002 (n = 19,003). MAIN OUTCOME VARIABLES: Weight satisfaction, weight-related health behaviors, chronic health conditions, and clinical health indicators. STATISTICAL ANALYSES PERFORMED: Chi-square test, t-tests, and linear and multivariate logistic regression. RESULTS: Compared to men, women were more likely to be dieting (32% women; 18% men) and had higher weight dissatisfaction. Men and women with greater weight dissatisfaction reported more dieting, yo-yo dieting, and snacking and consuming fewer meals, being less active, and having to eat either more or less than desired to maintain weight regardless of weight status. Those who were overweight or obese and dissatisfied with their weight had the poorest health. CONCLUSION: Greater satisfaction with one's weight was associated with positive health behaviors and health outcomes in both men and women and across weight status groups.

RESUMO

Community-based participatory research (CBPR) initiatives such as the National Cancer Institute's Community Networks Program (CNP) (2005-2010) often emphasize training of junior investigators from underrepresented backgrounds to address health disparities. From July to October 2010, a convenience sample of 80 participants from the 25 CNP national sites completed our 45-item, web-based survey on the training and mentoring of junior investigators. This study assessed the academic productivity and CBPR-related experiences of the CNP junior investigators (n=37). Those from underrepresented backgrounds reported giving more presentations in non-academic settings (nine vs. four in the last 5 years, p=0.01), having more co-authored publications (eight vs. three in the last 5 years, p=0.01), and spending more time on CBPR-related activities than their non-underrepresented counterparts. Regardless of background, junior investigators shared similar levels of satisfaction with their mentors and CBPR experiences. This study provides support for the success of the CNP's training program, especially effort directed at underrepresented investigators.

RESUMO

We tested the hypothesis that risk of early mortality from cancers of the digestive system will be greater in men with, compared with men without, the metabolic syndrome (MetS). Participants were 33,230 men who were seen at the Cooper Clinic in Dallas, TX, and followed for 14.4 (SD = 7.0) years. Metabolic syndrome was defined as having at least 3 of the following risk factors: abdominal obesity, fasting hypertriglyceridemia, low high-density lipoprotein cholesterol, high blood pressure, or high fasting glucose level or diabetes. Metabolic syndrome was associated with higher mortality (hazard ratio [HR] = 1.90 [95% confidence interval = 1.42-2.55]), and there was a graded positive association for the addition of more syndrome components (P < .01). Adjustment for cardiorespiratory fitness attenuated the risk estimates by 20% to 30%, but they remained significant after this adjustment. Evaluation of the independent contribution of each of the syndrome components revealed that both abdominal obesity (HR = 1.89 [1.36-2.62]) and high glucose (HR = 1.38 [1.02-1.87]) were independently associated with cancer mortality. Our results support the hypothesis that metabolic syndrome is positively associated with mortality from cancers of the digestive system. Interventions that reduce abnormalities associated with the syndrome could reduce risk of premature death from these cancers.

RESUMO

PURPOSE: Previous studies have suggested that higher levels of physical activity may lower lung cancer risk; however, few prospective studies have evaluated lung cancer mortality in relation to cardiorespiratory fitness (CRF), an objective marker of recent physical activity habits. METHODS: Thirty-eight thousand men, aged 20-84 yr, without history of cancer, received a preventive medical examination at the Cooper Clinic in Dallas, Texas, between 1974 and 2002. CRF was quantified as maximal treadmill exercise test duration and was grouped for analysis as low (lowest 20% of exercise duration), moderate (middle 40%), and high (upper 40%). RESULTS: A total of 232 lung cancer deaths occurred during follow-up (mean = 17 yr). After adjustment for age, examination year, body mass index, smoking, drinking, physical activity, and family history of cancer, hazard ratios (95% confidence intervals) for lung cancer deaths across low, moderate, and high CRF categories were 1.0, 0.48 (0.35-0.67), and 0.43 (0.28-0.65), respectively. There was an inverse association between CRF and lung cancer mortality in former (P for trend = 0.005) and current smokers (P for trend < 0.001) but not in never smokers (trend P = 0.14). Joint analysis of smoking and fitness status revealed a significant 12-fold higher risk of death in current smokers (hazard ratio = 11.9, 95% confidence interval = 6.0-23.6) with low CRF as compared with never smokers who had high CRF. CONCLUSIONS: Although the potential for some residual confounding by smoking could not be eliminated, these data suggest that CRF is inversely associated with lung cancer mortality in men. Continued study of CRF in relation to lung cancer, particularly among smokers, may further our understanding of disease etiology and reveal additional strategies for reducing its burden.
