RESUMEN

Mounting evidence suggests that weight management and physical activity (PA) improve overall health and well being, and reduce the risk of morbidity and mortality among cancer survivors. Although many opportunities exist to include weight management and PA in routine cancer care, several barriers remain. This review summarizes key topics addressed in a recent National Academies of Science, Engineering, and Medicine workshop entitled, "Incorporating Weight Management and Physical Activity Throughout the Cancer Care Continuum." Discussions related to body weight and PA among cancer survivors included: 1) current knowledge and gaps related to health outcomes; 2) effective intervention approaches; 3) addressing the needs of diverse populations of cancer survivors; 4) opportunities and challenges of workforce, care coordination, and technologies for program implementation; 5) models of care; and 6) program coverage. While more discoveries are still needed for the provision of optimal weight-management and PA programs for cancer survivors, obesity and inactivity currently jeopardize their overall health and quality of life. Actionable future directions are presented for research; practice and policy changes required to assure the availability of effective, affordable, and feasible weight management; and PA services for all cancer survivors as a part of their routine cancer care.

RESUMEN

Cancer screening behaviors in Muslims are under-researched, and there is limited data on how it relates to their unique cultural and religious beliefs. We assessed cancer prevention and screening-related health needs in the Washington DC area. We developed the needs assessment questionnaires and recruitment strategy in collaboration with key faith leaders from four mosques in our catchment area. A total of 203 participants were recruited through community outreach and engagement approaches and were included in the discussion when developing the needs assessment to ensure questions were religiously and culturally sensitive. Of the 203 participants, 56% of women reported receiving screening for a mammogram, while 83% of women reported receiving a screening for cervical cancer. Among men, 45% reported receiving a prostate cancer antigen test to screen for prostate cancer. Among both men and women, 35% reported ever receiving a screening for colorectal cancer. Women reported relying more on their faith when dealing with health concerns than men. Those who did not get screened for breast, colorectal, and cervical cancer relied more on their faith than those who did get screened for these cancers. Participants expressed interest in having health initiatives around cancer education, screening, and survivorship inside mosques. Faith beliefs can influence cancer screening behaviors; however, the relationship between these two variables needs further examination. Continued engagement with key faith leaders can help in leveraging religious beliefs to promote health education and cancer screening.

RESUMEN

BACKGROUND: Discrimination can adversely affect health and accelerate aging, but little is known about these relationships in cancer survivors. This study examines associations of discrimination and aging among self-identified African American survivors. METHODS: A population-based sample of 2232 survivors 20-79 years old at diagnosis were enrolled within 5 years of breast (n = 787), colorectal (n = 227), lung (n = 223), or prostate (n = 995) cancer between 2017 and 2022. Surveys were completed post-active therapy. A deficit accumulation index measured aging-related disease and function (score range, 0-1, where <0.20 is robust, 0.20 to <0.35 is pre-frail, and 0.35+ is frail; 0.06 is a large clinically meaningful difference). The discrimination scale assessed ever experiencing major discrimination and seven types of events (score, 0-7). Linear regression tested the association of discrimination and deficit accumulation, controlling for age, time from diagnosis, cancer type, stage and therapy, and sociodemographic variables. RESULTS: Survivors were an average of 62 years old (SD, 9.6), 63.2% reported ever experiencing major discrimination, with an average of 2.4 (SD, 1.7) types of discrimination events. Only 24.4% had deficit accumulation scores considered robust (mean score, 0.30 [SD, 0.13]). Among those who reported ever experiencing major discrimination, survivors with four to seven types of discrimination events (vs. 0-1) had a large, clinically meaningful increase in adjusted deficits (0.062, p < .001) and this pattern was consistent across cancer types. CONCLUSION: African American cancer survivors have high deficit accumulated index scores, and experiences of major discrimination were positively associated with these deficits. Future studies are needed to understand the intersectionality between aging, discrimination, and cancer survivorship among diverse populations.

RESUMEN

Annual lung cancer screening (LCS) is recommended for individuals at high risk for lung cancer. However, primary care provider-initiated discussions about LCS and referrals for screening are low overall, particularly among Black or African Americans and other minoritized racial and ethnic groups. Disparities also exist in receiving provider advice to quit smoking. Effective methods are needed to improve provider knowledge about LCS and tobacco-related disparities, and to provide resources to achieve equity in LCS rates. We report the feasibility and impact of pairing a self-directed Lung Cancer Health Disparities (HD) Web-based course with the National Training Network Lung Cancer Screening (LuCa) course on primary care providers' knowledge about LCS and the health disparities associated with LCS. In a quasi-experimental study, primary care providers (N = 91) recruited from the MedStar Health System were assigned to complete the LuCa course only vs. the LuCa + HD courses. We measured pre-post-LCS-related knowledge and opinions about the courses. The majority (60.4%) of providers were resident physicians. There was no significant difference between groups on post-test knowledge (p > 0.05). However, within groups, there was an improvement in knowledge from pre- to post-test (LuCa only (p = 0.03); LuCa + HD (p < 0.001)). The majority of providers (81%) indicated they planned to improve their screening and preventive practices after having reviewed the educational modules. These findings provide preliminary evidence that this e-learning course can be used to educate providers on LCS, smoking cessation, and related disparities impacting patients.

RESUMEN

While excess weight is an established risk factor for postmenopausal breast cancer, consideration of maximum body mass index (maxBMI; BMI is calculated as weight (kg)/height (m)2) or BMI at a point in time relevant for breast carcinogenesis may offer new insights. We prospectively evaluated maxBMI and time-dependent BMI in relation to breast cancer incidence among 31,028 postmenopausal women in the Black Women's Health Study. During 1995-2015, a total of 1,384 diagnoses occurred, including 787 estrogen-receptor (ER)-positive (ER+) cases and 310 ER-negative (ER-) cases. BMI was assessed at baseline and 2, 4, 6, and 8 years before diagnosis. Cox proportional hazards regression was used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). Compared with women with BMI <25, those with BMI ≥35 had increased risk of ER+ breast cancer but not ER- breast cancer. For BMI assessed 2 years before diagnosis, the HRs for ER+ breast cancer associated with maxBMI ≥35 and time-dependent BMI ≥35 were 1.42 (95% confidence interval (CI): 1.10, 1.84) and 1.63 (95% CI: 1.25, 2.13), respectively. The corresponding HR for time-dependent BMI assessed 6 years before diagnosis was 1.95 (95% CI: 1.45, 2.62). These findings suggest strong associations of BMI with risk of ER+ breast cancer in postmenopausal women, regardless of timing of BMI assessment.

RESUMEN

BACKGROUND: In 2021, the US Preventive Services Task Force (USPSTF) expanded the eligibility criteria for low-dose computed tomographic lung cancer screening (LCS) to reduce racial disparities that resulted from the 2013 USPSTF criteria. The annual LCS rate has risen slowly since the 2013 USPSTF screening recommendations. Using the 2019 Behavioral Risk Factor Surveillance System (BRFSS), this study 1) describes LCS use in 2019, 2) compares the percent eligible for LCS using the 2013 versus 2021 USPSTF criteria, and 3) determines the percent eligible using the more detailed PLCOm2012Race3L risk-prediction model. METHODS: The analysis included 41,544 individuals with a smoking history from states participating in the BRFSS LCS module who were ≥50 years old. RESULTS: Using the 2013 USPSTF criteria, 20.7% (95% confidence interval [CI], 19.0-22.4) of eligible individuals underwent LCS in 2019. The 2013 USPSTF criteria was compared to the 2021 USPSTF criteria, and the overall proportion eligible increased from 21.0% (95% CI, 20.2-21.8) to 34.7% (95 CI, 33.8-35.6). Applying the 2021 criteria, the proportion eligible by race was 35.8% (95% CI, 34.8-36.7) among Whites, 28.5% (95% CI, 25.2-31.9) among Blacks, and 18.0% (95% CI, 12.4-23.7) among Hispanics. Using the 1.0% 6-year threshold that is comparable to the 2021 USPSTF criteria, the PLCOm2012Race3L model selected more individuals overall and by race. CONCLUSIONS: Using data from 20 states and using multiple imputation, higher LCS rates have been reported compared to prior BRFSS data. The 2021 expanded criteria will result in a greater number of screen-eligible individuals. However, risk-based screening that uses additional risk factors may be more inclusive overall and across subgroups. LAY SUMMARY: In 2013, lung cancer screening (lung screening) was recommended for high risk individuals. The annual rate of lung screening has risen slowly, particularly among Black individuals. In part, this racial disparity resulted in expanded 2021 criteria. Survey data was used to: 1) describe the number of people screened in 2019, 2) compare the percent eligible for lung screening using the 2013 versus 2021 guidelines, and 3) determine the percent eligible using more detailed criteria. Lung screening rates increased in 2019, and the 2021 criteria will result in more individuals eligible for screening. Using additional criteria may identify more individuals eligible for lung screening.

RESUMEN

BACKGROUND: Black Americans have the highest incidence of colorectal cancer (CRC) of any racial/ethnic group in the United States. High intake of red and processed meats has been associated with an increased CRC risk in predominately White populations. However, 3 prior studies in Black populations, who have been reported to have high intakes of red and processed meats, have reported no associations. Data on a possible association between CRC risk and SFAs and MUFAs, the primary types of fat in red and processed meats, are inconclusive. OBJECTIVES: We prospectively assessed intakes of processed and unprocessed red meat, SFAs, and MUFAs in relation to CRC risk, utilizing data from the Black Women's Health Study (BWHS, 1995-2018). METHODS: Dietary data were derived from validated FFQs completed in 1995 and 2001. Multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox proportional hazards regression. RESULTS: Among 52,695 BWHS participants aged 21-69 y at baseline and followed for ≤22 y, 564 women developed incident CRC. Unprocessed red meat intake was associated with a 33% increased CRC risk per 100 g/d (HR: 1.33; 95% CI: 1.03-1.71). Examination of CRC anatomic sites revealed that unprocessed red meat was associated with 2-times increased rectal cancer risk (HR: 2.22; 95% CI: 1.15-4.26). There was no evidence of an interaction with age (pinteraction = 0.4), but unprocessed red meat intake was only associated with a significant increased risk of late-onset CRC (≥50 y of age, HR: 1.41; 95% CI: 1.05-1.88). Processed red meat and total SFA and MUFA intakes were not associated with CRC risk. CONCLUSIONS: Unprocessed red meat intake was associated with an increased CRC risk in the present study, the first positive evidence that red meat plays a role in the etiology of CRC in Black women. The findings suggest prevention opportunities.

RESUMEN

BACKGROUND: Triple-negative breast cancer (TNBC) has a high recurrence risk and poor clinical outcomes. Associations between metabolic syndrome (MetS) risk components and mortality in postmenopausal women with TNBC were examined in the Women's Health Initiative. METHODS: Five hundred forty-four postmenopausal women were diagnosed with nonmetastatic TNBC. Baseline risk components included a high waist circumference (≥88 cm), high blood pressure, hypercholesterolemia, and diabetes. Groups were categorized by the number of MetS risk components: none, 1 or 2, or 3 or 4. Hazard ratios (HRs) and 95% confidence intervals (CIs) across groups were computed with multivariable adjusted Cox models. Outcomes included breast cancer-specific mortality and breast cancer overall mortality (breast cancer followed by death from any cause). Variables in the multivariable model included age at TNBC diagnosis; race/ethnicity; income; education; clinical/observational trial status; history of oral contraceptive, hormone, and/or statin use; cancer stage; and chemotherapy and/or radiation treatment status. RESULTS: Of the 544 participants with TNBC, 33% had no MetS risk components (n = 178), 59% had 1 or 2 risk components (n = 323), and 8% had 3 or 4 risk components (n = 43). After a median follow-up from diagnosis of 8.3 years, multivariable results showed that women with 3 or 4 risk components had a nonsignificantly higher risk of breast cancer mortality (HR, 2.05; 95% CI, 0.94-4.47 trend P = .114) and a significantly higher risk of overall mortality (HR, 2.13; 95% CI, 1.22-3.71; trend P = .006) versus women with 0 risk components. CONCLUSIONS: Postmenopausal women with TNBC and 3 or 4 MetS risk components have a nonsignificantly higher breast cancer mortality risk and a significantly higher overall mortality risk, likely because of negative influences of metabolic risk factors on several causes of death.

RESUMEN

LESSONS LEARNED: Despite U.S. Food and Drug Administration approval to reduce alopecia, data on efficacy of scalp cooling in Black patients with cancer are limited by lack of minority representation in prior clinical trials. Scalp cooling devices may have less efficacy in Black patients; additional studies are required to explore the possible causes for this, including hair texture and cap design. BACKGROUND: The Paxman scalp cooling (SC) device is U.S. Food and Drug Administration (FDA)-approved for prevention of chemotherapy-induced alopecia. Studies report 50%-80% success rates and high patient satisfaction, yet there have been no studies of SC in Black patients. We conducted a phase II feasibility study of Paxman SC with a planned enrollment of 30 Black patients receiving chemotherapy for stage I-III breast cancer. METHODS: Black patients who planned to receive at least four cycles of chemotherapy with non-anthracycline (NAC) or anthracycline (AC) regimens were eligible. Alopecia was assessed by trained oncology providers using the modified Dean scale (MDS) prior to each chemotherapy session. Distress related to alopecia was measured by the Chemotherapy Alopecia Distress Scale (CADS). RESULTS: Fifteen patients enrolled in the intervention before the study was closed early because of lack of efficacy. Median MDS and CADS increased after SC, suggesting increased hair loss (p < .001) and alopecia distress (p = .04). Only one participant was successful in preventing significant hair loss; the majority stopped SC before chemotherapy completion because of grade 3 alopecia (>50% hair loss). CONCLUSION: SC may not be efficacious in preventing alopecia in Black women. Differences in hair thickness, hair volume, and limitations of cooling cap design are possible contributing factors.

RESUMEN

African-American/Black women have more aggressive breast cancer subtypes, are diagnosed at younger ages, and have an increasing incidence rate. These disparities have resulted in Black women continuing to experience the highest mortality rate from breast cancer of any US racial or ethnic group. However, national screening mammography guidelines do not reflect the high-risk status of Black women. Here we review breast cancer screening guidelines and address the lack of inclusion of the specific needs of Black women. In order to equitably care for the health needs of Black women, high-risk designation would improve access to earlier screening and supplemental imaging including breast MRI.

RESUMEN

In this era of effective combination antiretroviral therapy the incidence of AIDS defining cancers (ADCs) is projected to decline while the incidence of certain non-AIDS defining cancers (NADCs) increases. Some of these NADCs are potentially preventable with appropriate cancer screening. We examined cancer incidence, screening eligibility, and receipt of screening among persons actively enrolled in the DC Cohort, a longitudinal observational cohort of PLWH, between 2011 and 2017. Cancer screening eligibility was determined based on age, sex, smoking history and co-morbidity data available and published national guidelines. The incidence rate of NADCs was 12.1 (95% CI 10.7, 13.8) and ADCs 1.6 (95% CI 0.6, 4.6) per 1000 person-years. The most common incident NADCs were breast 2.6 (95% CI 0.5,1 2.1), prostate 2.3 (95% CI 1.2, 4.3), and non-melanoma skin 1.2 (95% CI 0.6, 2.3) incident diagnoses/cases per 1000 person-years. Among cohort sites where receipt of cancer screening was assessed, less than 60% of eligible participants had any ascertained anal HPV, breast, cervical, colorectal, hepatocellular carcinoma, or lung cancer screening. In this cohort of PLWH, there were more incident NADCs versus ADCs in contrast to earlier cohort studies where ADCs predominated. Despite a large eligible population there were low rates of screening. Implementation of cancer screening is an important component of care among PLWH.

RESUMEN

BACKGROUND: Physical activity (PA) is recommended for women with breast cancer (BC); however, data are sparse on the association of PA with quality of life (QOL) and patient-reported symptoms for women on adjuvant endocrine therapy (AET). METHODS: Women with hormone receptor-positive BC who were taking AET completed standardized surveys about their health-related QOL, AET-related symptoms, and levels of PA using validated measures. A Wald chi-square test and an analysis of variance were used to assess associations with PA and independent variables. Generalized linear regression analyses assessed associations between PA, QOL, and AET-related symptoms. RESULTS: The analytic cohort included 485 Black and White women. Black race, a high body mass index (BMI), and being on aromatase inhibitors (vs tamoxifen) were associated with lower PA in a bivariate analysis. In a multivariate analysis, lower self-reported PA was associated with a high BMI (P = .02) and chemotherapy uptake (P = .006). Better health-related QOL (P = .01), less severe overall AET-related symptoms (P = .02), and less severe gynecological symptoms (P = .03) were associated with increasing levels of moderate PA. CONCLUSIONS: Among women taking AET, moderate levels of PA may be associated with fewer medication-related symptoms and overall better ratings of health-related QOL. Because of the low levels of PA observed in the sample overall and particularly for Black women, identifying successful strategies to promote PA are needed.

RESUMEN

BACKGROUND: Insulin resistance is associated with higher all-cause and cancer-specific mortality in postmenopausal women. However, to the authors' knowledge, information regarding insulin resistance and breast cancer mortality risk is limited. Therefore, the authors examined associations between insulin resistance and breast cancer incidence and mortality in a subsample of Women's Health Initiative participants. METHODS: A total of 22,837 postmenopausal women with fasting baseline glucose and insulin levels were followed for incident breast cancer and breast cancer mortality. Breast cancers were verified by medical record review and serial National Death Index linkage-enhanced mortality findings. Insulin resistance was estimated using the homeostatic model assessment of insulin resistance (HOMA-IR). Multivariable Cox proportional hazards models were used to compute hazard ratios (HRs) with 95% confidence intervals (95% CIs) for quartile comparisons. Outcomes included breast cancer incidence, deaths from breast cancer, and deaths after breast cancer (breast cancer followed by death from any cause). RESULTS: During a median of 19.8 years of follow-up of 1328 breast cancer cases, there were 512 deaths reported, 151 of which were from breast cancer. Breast cancer incidence was higher in women in the highest HOMA-IR quartile (HR, 1.34; 95% CI, 1.12-1.61 [P for trend = .003]). Although HOMA-IR was not found to be associated with risk of death from breast cancer (HR, 1.04; 95% CI, 0.60-1.79), women in the highest versus those in the lowest HOMA-IR quartile were at a higher risk of death after breast cancer (HR, 1.78; 95% CI, 1.32-2.39 [P for trend <.001]). CONCLUSIONS: Higher levels of insulin resistance in postmenopausal women are associated with higher breast cancer incidence and higher all-cause mortality after breast cancer.

RESUMEN

PURPOSE: Evidence for the association of anthropometrics with colorectal neoplasms is limited for African Americans. METHODS: We examined anthropometric measures with both colorectal adenoma and colorectal cancer (CRC) risk in the ongoing Black Women's Health Study. In a nested case-control analysis, 954 cases of colorectal adenoma were compared with 3,816 polyp-free controls, matched on age and follow-up time. For the CRC analyses, 413 incident CRC cases were identified over a 16-year follow-up (802,783 person-years). Adenoma cases and CRC were verified by medical record review. We used multivariable conditional logistic regression analyses (for adenoma) and Cox proportional hazards analyses (for CRC) that included anthropometric exposures and selected confounders. RESULTS: Overall body mass index (BMI) and other anthropometric factors were not associated with colorectal adenoma or cancer risk in Black women. However, increased risk of adenoma (but not CRC) was observed among especially related to adenomas in the proximal colon. Among women ≥ 50 years of age, risk of proximal adenoma increased 14% (95% CI 1.00, 1.31), 35% (95% CI 1.12, 1.63), and 25% (0.93, 1.68) with each standard deviation increase in BMI, waist circumference, and waist-to-hip ratio, respectively. None of the anthropometric factors were associated with young onset CRC or adenoma risk. CONCLUSION: Our results suggest that obesity might be an initiator for colon adenomas but not a promoter for colorectal cancer among Black women.

RESUMEN

BACKGROUND: This study examined the effects of supervised and home-based exercise interventions on changes in metabolic syndrome (MetS) according to breast cancer risk (high vs low) in black women enrolled in the Focused Intervention on Exercise to Reduce Cancer (FIERCE) trial. METHODS: Postmenopausal, obese, metabolically unhealthy black women, 45 to 65 years old, were randomized to supervised aerobic exercise (73 women), home-based walking-based exercise (69 women), or a control arm (71 women). Participants in the exercise arms underwent a 6-month intervention with study assessments conducted at the baseline and 6 months. The primary outcome measure was MetS (fasting glucose, waist circumference, blood pressure, serum triglycerides, and high-density lipoprotein [HDL]). The intervention effects on MetS, stratified by breast cancer risk as measured by the family history of breast cancer and model-based projected breast cancer risk, were examined with intent-to-treat analyses using generalized estimating equation models. RESULTS: Among women with a family history of breast cancer, the exercise arms had lower mean MetS z scores, which suggested an improvement in the metabolic profile, than controls at 6 months (controls, + 0.55; home-based arm, -0.97, P < .01; supervised arm, -0.89, P < .01). Stratified analyses by projected breast cancer risk suggested similar but statistically nonsignificant findings, with those at high risk having more favorable changes in the MetS z score in the exercise arms versus the control arm. These changes were primarily attributable to changes in blood pressure, triglycerides, and HDL. CONCLUSIONS: Short-term aerobic activity regimens may improve the metabolic profile and thereby reduce breast cancer risk in obese, metabolically unhealthy black women at high risk for cancer. © 2018 American Cancer Society.

RESUMEN

This project evaluated associations between fruit and vegetable intake, cigarette smoking and lung cancer incidence among U.S. Black women. The Black Women's Health Study is a prospective cohort study (analytic cohort = 46,889) among Black women between the ages 21 and 69 at baseline (1995). Fruit and vegetable intake and smoking history were ascertained via questionnaires at baseline and during follow-up. Associations between fruit and vegetable intake, smoking and lung cancer incidence (N = 306 incident cases through 2013) were evaluated using Cox proportional hazards regression. Among women in this cohort, 6.1% and 5.6% reported consuming at least three servings/d of fruit or vegetables, respectively. Smoking history was associated with increased lung cancer incidence. Being a current smoker of ≥15 cigarettes/d was associated with higher lung cancer incidence compared to never smokers (HR = 17.4, 95% CI: 11.5, 26.4). Fruit and vegetable was not associated with lung cancer incidence intake (≥5 vs. <3 servings/d, adjusted HR: 0.86, 95% CI: 0.54, 1.36). Associations between fruit and vegetable intake and lung cancer incidence did not differ by smoking history. Fruit and vegetable intake was low in this study population, but results do not support an association between fruit and vegetable intake and lung cancer incidence, regardless of smoking history.

RESUMEN

Data on ethnic variations in breast density are limited and often not inclusive of underrepresented minorities. As breast density is associated with elevated breast cancer risk, investigating racial and ethnic difference may elucidate the observed differences in breast cancer risk among different populations. We reviewed breast density from initial screening of women from the Capital Breast Care Center and Georgetown University Hospital from 2010 to 2014. Patient demographics including race, age at screening, education, menopausal status, and body mass index were abstracted. We recorded the BI-RADS density categories: (1) "fatty," (2) "scattered fibroglandular densities," (3) "heterogeneously dense," and (4) "extremely dense." Multivariable unconditional logistic regression was used to identify predictors of breast density. Density categorization was recorded for 2146 women over the 5-year period, comprising Blacks (n = 940), Hispanics (n = 893), and Whites (n = 314). Analysis of subject characteristics by breast density showed that high category is observed in younger, Hispanic, nulliparous, premenopausal, and nonobese women (t-test or chi-square test, P-values <.0001). Obese women are 70% less likely to have high density. Being Hispanic, premenopausal, and nonobese were predictive of high density on logistic regression. In this analysis of density distribution in a diverse sample, Hispanic women have the highest breast density, followed by Blacks and Whites. Unique in our findings is women who identify as Hispanic have the highest breast density and lower rates of obesity. Further investigation of the impact of obesity on breast density, especially in the understudied Hispanic group is needed.

RESUMEN

This study developed and examined the reach and impact of a culturally appropriate mass media campaign pilot, designed to increase awareness about the importance of mammography screening and the available community mammography services for low-income African American women ages 40 and above. We conducted formative research using focus groups to inform campaign development, resulting in five emergent themes-good breast health, holistic views of healthiness, cancer fatalism, fear of mammogram machines, and mammogram affordability. The campaign targeted specific low-income African American communities in the District of Columbia via print ads in Metro stations and on buses, print ads in the Washington Informer, and online ads on a local TV network website. Data were collected before, during, and after campaign implementation to assess reach and impact. Reach was measured by number of impressions (number of people exposed to the campaign), while impact was assessed via online ad click-through rates, website use and referrals, and mammography center calls. The campaign was successful in reaching the target audience, with a total combined reach from all media of 9,479,386 impressions. In addition, the mammography center received significant increases in new website visitors (1482 during the campaign, compared to 24 during the preceding period) as well as 97 calls to the dedicated phone line. Further research involving a more long-term investment in terms of funding and campaign run time, coupled with a more robust evaluation, is needed to assess if culturally appropriate mass media campaigns can generate increased mammography screening rates and decrease breast-cancer-related mortality.

RESUMEN

Washington, DC, has one of the highest incidence and mortality rates for breast cancer in the USA. Patient navigation coupled with informational and community resources are important strategies that assist patients' access and help them understand the complex world of cancer care. The Georgetown Lombardi Comprehensive Cancer Center's Capital Breast Care Center (CBCC) is a safety net mammography screening center that utilizes a community-based navigation program. In addition to providing assistance with coordination of clinical services, navigators at CBCC are integral in establishing intra-community partnerships to educate members of the community about breast cancer screening. The aim of this study was to detail the role of patient navigation at the CBCC, with an emphasis on community engagement and community-based partnerships. We describe the process by which CBCC established partnerships with multiple community organizations between 2004 and 2015 and analyzed data of women screened in relationship to the evolution of the patient navigation services. Application of the CBCC navigation model that integrates individual patient outreach with community engagement has yielded viable and lasting community partnerships that have resulted in an increase in mammography uptake, especially among medically underserved minority women.
