Creating and Implementing a Community Engagement Strategy for the 2022-2027 Illinois Comprehensive Cancer Control Plan Through an Academic-State Public Health Department Partnership.

INTRODUCTION: Comprehensive cancer control (CCC) plans are state-level blueprints that identify regional cancer priorities and health equity strategies. Coalitions are encouraged to engage with community members, advocacy groups, people representing multiple sectors, and working partners throughout the development process. We describe the community and legislative engagement strategy developed and implemented during 2020-2022 for the 2022-2027 Illinois CCC plan. METHODS: The engagement strategies were grounded in theory and evidence-based tools and resources. It was developed and implemented by coalition members representing the state health department and an academic partner, with feedback from the larger coalition. The strategy included a statewide town hall, 8 focus groups, and raising awareness of the plan among state policy makers. RESULTS: A total of 112 people participated in the town hall and focus groups, including 40 (36%) cancer survivors, 31 (28%) cancer caregivers, and 18 (16%) Latino and 26 (23%) African American residents. Fourteen of 53 (26%) focus group participants identified as rural. Participants identified drivers of cancer disparities (eg, lack of a comprehensive health insurance system, discrimination, transportation access) and funding and policy priorities. Illinois House Resolution 0675, the Illinois Cancer Control Plan, was passed in March 2022. CONCLUSION: The expertise and voices of community members affected by cancer can be documented and reflected in CCC plans. CCC plans can be brought to the attention of policy makers. Other coalitions working on state plans may consider replicating our strategy. Ultimately, CCC plans should reflect health equity principles and prioritize eliminating cancer disparities.

Pilot study of a culturally sensitive intervention to promote genetic counseling for breast cancer risk.

BACKGROUND: Despite the benefits of genetic counseling and testing, uptake of cancer genetic services is generally low and Black/African American (Black) women are substantially less likely to receive genetic services than non-Hispanic White women. Our team developed a culturally sensitive, narrative decision aid video to promote uptake of genetic counseling among Black women at risk for a hereditary breast cancer syndrome that can be incorporated in conjunction with population-based cancer risk assessment in a clinical setting. We report here a pilot study to demonstrate changes in intention to access genetic counseling and intervention satisfaction. METHODS: Black women who were personally unaffected by breast cancer and were recommended for genetic counseling based on family history screening in a mammography center were recruited at the time of the mammogram. A prospective, pre-post survey study design, guided by theoretical constructs, was used to evaluate baseline and immediate post-intervention psychosocial factors, including intention to participate in genetic counseling and intervention satisfaction. RESULTS: Pilot recruitment goals were met (n = 30). Pre-intervention, 50% of participants indicated that they were extremely likely to make a genetic counseling appointment, compared with 70% post-intervention (p = 0.05). After watching the intervention, 50% of participants indicated that the video changed their mind regarding genetic counseling. CONCLUSIONS: This study demonstrated cultural satisfaction with a decision aid intervention designed to motivate Black women with hereditary breast cancer risk to attend a genetic counseling appointment. Our study showed that intention may be a specific and key construct to target in interventions designed to support decision-making about genetic services. Study results informed the design of a subsequent large scale, randomized implementation study. TRIAL REGISTRATION: Trial registration: Clinicaltrials.gov NCT04082117 . Registered September 9, 2019. Retrospectively registered.

Development of a culturally sensitive narrative intervention to promote genetic counseling among African American women at risk for hereditary breast cancer.

BACKGROUND: African American women with hereditary breast cancer risk are less likely to undergo genetic counseling and testing compared with non-Hispanic White women. Inequities in the use of precision cancer care are likely to exacerbate racial disparities in cancer outcomes. A culturally sensitive multimedia narrative intervention was developed to motivate African American women at risk for hereditary breast cancer to engage in genetic counseling. METHODS: Development of the intervention was grounded in the Integrative Model of Behavioral Prediction using a phenomenological, deductive approach and employed multiple qualitative methods for data collection, including 1-on-1 interviews and story circles with members of the target audience to identify salient themes and lived experiences. Focus group testing was then conducted with members of the group of focus, primary care providers, and community stakeholders. RESULTS: Six themes that mapped to the theoretical model were identified. Lived experiences were abstracted from story circle data to create a narrative storyline. Educational content and motivational messaging derived from the 6 themes were embedded into the script. Focus group testing with stakeholder groups was used to refine the intervention. Testing of the final multimedia narrative with focus groups indicated that the intervention was culturally sensitive and authentic, and the messaging was effective. CONCLUSIONS: Multiple qualitative data collection methods and a robust theoretical framework of health behavior were key elements for this study to develop a culturally sensitive, narrative intervention that reflects lived experiences and motivates underserved African American women with hereditary breast cancer risk to engage in genetic counseling. This strategy can be applied to mitigate racial inequities in the use of other genomic approaches for personalizing cancer care.

Cholangiocarcinoma Among Children and Adolescents: A Review of the Literature and Surveillance, Epidemiology, and End Results Program Database Analysis.

OBJECTIVE: Cholangiocarcinoma (CCA) is a biliary malignancy found primarily in adults. The incidence of CCA in children is unknown. The aim of this study was to describe characteristics of CCA in children and adolescents. METHODS: Using the Surveillance, Epidemiology, and End Results Program (SEER 18) database, we identified incident cases of CCA diagnosed at <20 years of age during the period of 1973 to 2013. Additionally, we reviewed published case reports describing pediatric patients with CCA. We calculated descriptive statistics for CCA cases identified in SEER and in case reports. Kaplan-Meier analysis was performed to determine median and 3-year overall survival (OS) rates. RESULTS: We identified 15 children and adolescents diagnosed as having CCA from SEER 18 with an incidence rate of 0.0036 per 100,000. Two-thirds of cases were male, and the majority were white (n = 10). The median age at diagnosis was 17 years (range: 11-19 years). Nine tumors were intrahepatic, 3 extrahepatic, and 3 unspecified. One-third had distal metastases at diagnosis. Eight patients underwent surgical resection including liver transplant in two. Six patients were alive at the time of follow-up. Patients without surgical treatment did not survive. Three-year OS was 50%. Twenty-two children with CCA were found in the literature with a median age at diagnosis of 15 years (range: 3-18 years). Half were male, and 90% had an underlying gastrointestinal comorbidity. Three-year OS was 35.3%. CONCLUSIONS: CCA in children and adolescents is rare with poor survival. A high proportion of cases had a history of biliary disease. Surgical resection is necessary for cure.

Race and BMI modify associations of calcium and vitamin D intake with prostate cancer.

BACKGROUND: African Americans have disproportionately higher burden of prostate cancer compared to European Americans. However, the cause of prostate cancer disparities is still unclear. Several roles have been proposed for calcium and vitamin D in prostate cancer pathogenesis and progression, but epidemiologic studies have been conducted mainly in European descent populations. Here we investigated the association of calcium and vitamin D intake with prostate cancer in multiethnic samples. METHODS: A total of 1,657 prostate cancer patients who underwent screening and healthy controls (888 African Americans, 620 European Americans, 111 Hispanic Americans, and 38 others) from Chicago, IL and Washington, D.C. were included in this study. Calcium and vitamin D intake were evaluated using food frequency questionnaire. We performed unconditional logistic regression analyses adjusting for relevant variables. RESULTS: In the pooled data set, high calcium intake was significantly associated with higher odds for aggressive prostate cancer (ORQuartile 1 vs. Quartile 4 = 1.98, 95% C.I.: 1.01-3.91), while high vitamin D intake was associated with lower odds of aggressive prostate cancer (ORQuartile 1 vs. Quartile 4 = 0.38, 95% C.I.: 0.18-0.79). In African Americans, the association between high calcium intake and aggressive prostate cancer was statistically significant (ORQuartile 1 vs. Quartile 4 = 4.28, 95% C.I.: 1.70-10.80). We also observed a strong inverse association between total vitamin D intake and prostate cancer in African Americans (ORQuartile 1 vs. Quartile 4 = 0.06, 95% C.I.: 0.02-0.54). In European Americas, we did not observe any significant associations between either calcium or vitamin D intake and prostate cancer. In analyses stratifying participants based on Body Mass Index (BMI), we observed a strong positive association between calcium and aggressive prostate cancer and a strong inverse association between vitamin D intake and aggressive prostate cancer among men with low BMI (<27.8 kg/m2), but not among men with high BMI (≥27.8 kg/m2). Interactions of race and BMI with vitamin D intake were significant (P Interaction < 0.05). CONCLUSION: Calcium intake was positively associated with aggressive prostate cancer, while vitamin D intake exhibited an inverse relationship. However, these associations varied by race/ethnicity and BMI. The findings from this study may help develop better prostate cancer prevention and management strategies.

Common vitamin D pathway gene variants reveal contrasting effects on serum vitamin D levels in African Americans and European Americans.

Vitamin D deficiency is more common among African Americans (AAs) than among European Americans (EAs), and epidemiologic evidence links vitamin D status to many health outcomes. Two genome-wide association studies (GWAS) in European populations identified vitamin D pathway gene single-nucleotide polymorphisms (SNPs) associated with serum vitamin D [25(OH)D] levels, but a few of these SNPs have been replicated in AAs. Here, we investigated the associations of 39 SNPs in vitamin D pathway genes, including 19 GWAS-identified SNPs, with serum 25(OH)D concentrations in 652 AAs and 405 EAs. Linear and logistic regression analyses were performed adjusting for relevant environmental and biological factors. The pattern of SNP associations was distinct between AAs and EAs. In AAs, six GWAS-identified SNPs in GC, CYP2R1, and DHCR7/NADSYN1 were replicated, while nine GWAS SNPs in GC and CYP2R1 were replicated in EAs. A CYP2R1 SNP, rs12794714, exhibited the strongest signal of association in AAs. In EAs, however, a different CYP2R1 SNP, rs1993116, was the most strongly associated. Our models, which take into account genetic and environmental variables, accounted for 20 and 28 % of the variance in serum vitamin D levels in AAs and EAs, respectively.

Fine-mapping of IL16 gene and prostate cancer risk in African Americans.

BACKGROUND: Prostate cancer is the most common type of cancer among men in the United States, and its incidence and mortality rates are disproportionate among ethnic groups. Although genome-wide association studies of European descents have identified candidate loci associated with prostate cancer risk, including a variant in IL16, replication studies in African Americans (AA) have been inconsistent. Here we explore single-nucleotide polymorphism (SNP) variation in IL16 in AAs and test for association with prostate cancer. METHODS: Association tests were conducted for 2,257 genotyped and imputed SNPs spanning IL16 in 605 AA prostate cancer cases and controls from Washington, D.C. Eleven of them were also genotyped in a replication population of 1,093 AAs from Chicago. We tested for allelic association adjusting for age, global and local West African ancestry. RESULTS: Analyses of genotyped and imputed SNPs revealed that a cluster of IL16 SNPs were significantly associated with prostate cancer risk. The strongest association was found at rs7175701 (P = 9.8 × 10(-8)). In the Chicago population, another SNP (rs11556218) was associated with prostate cancer risk (P = 0.01). In the pooled analysis, we identified three independent loci within IL16 that were associated with prostate cancer risk. SNP expression quantitative trait loci analyses revealed that rs7175701 is predicted to influence the expression of IL16 and other cancer-related genes. CONCLUSION: Our study provides evidence that IL16 polymorphisms play a role in prostate cancer susceptibility among AAs. IMPACT: Our findings are significant given that there has been limited focus on the role of IL16 genetic polymorphisms on prostate cancer risk in AAs.

Establishing developmental genetics in a self-fertilizing fish (Krytolebias marmoratus).

Kryptolebias marmoratus is a synchronous hermaphroditic vertebrate that utilizes an ovotestis for reproduction. This fish develops externally, is easy to maintain, and has about a 100-day life cycle, making it a desirable developmental genetic model organism. Here, we present a pilot zygotic mutant screen utilizing the common chemical mutagen, N-ethyl-N-nitrosourea (ENU) to establish genetics in this model species. Selection of clonal stocks and optimal conditions for mutagenizing this fish are presented and the types and frequencies of zygotic mutants are documented in comparison to other fish models. Kryptolebias marmoratus is an exemplar model organism that will complement future developmental genetic screens in vertebrates.
