Background. Population-based studies are needed to estimate the prevalence of underweight or overweight/obese childhood cancer survivors. Procedure. Adult survivors (diagnosed ≤20 years) were identified from the linked Utah Cancer Registry and Utah Population Database. We included survivors currently aged ≥20 years and ≥5 years from diagnosis (N=1060), and a comparison cohort selected on birth year and sex (N=5410). BMI was calculated from driver license data available from 2000 to 2010. Multivariable generalized linear regression models were used to calculate prevalence relative risks (RR) and 95% confidence intervals (95% CI) of BMI outcomes for survivors and the comparison cohort. Results. Average time since diagnosis was 18.5 years (SD=7.8), and mean age at BMI for both groups was 30.5 (survivors SD=7.7, comparison SD=8.0). Considering all diagnoses, survivors were not at higher risk for being underweight or overweight/obese than the comparison. Male central nervous system tumor survivors were overweight (RR=1.12, 95% CI 1.01–1.23) more often than the comparison. Female survivors, who were diagnosed at age 10 and under, had a 10% higher risk of being obese than survivors diagnosed at ages 16–20 (P

How care delivery influences urban-rural disparities in cancer outcomes is unclear. We sought to understand community oncologists' practice settings to inform cancer care delivery interventions.We conducted secondary analysis of a national dataset of providers billing Medicare from June 1, 2019 to May 31, 2020 in 13 states in the central United States. We used Kruskal-Wallis rank and Fisher's exact tests to compare physician characteristics and practice settings among rural and urban community oncologists.We identified 1,963 oncologists practicing in 1,492 community locations; 67.5% practiced in exclusively urban locations, 11.3% in exclusively rural locations, and 21.1% in both rural and urban locations. Rural-only, urban-only, and urban-rural spanning oncologists practice in an average of 1.6, 2.4, and 5.1 different locations, respectively. A higher proportion of rural community sites were solo practices (11.7% vs 4.0%, P.001) or single specialty practices (16.4% vs 9.4%, P.001); and had less diversity in training environments (86.5% vs 67.8% with2 medical schools represented, P.001) than urban community sites. Rural multispecialty group sites were less likely to include other cancer specialists.We identified 2 potentially distinct styles of care delivery in rural communities, which may require distinct interventions: (1) innovation-isolated rural oncologists, who are more likely to be solo providers, provide care at few locations, and practice with doctors with similar training experiences; and (2) urban-rural spanning oncologists who provide care at a high number of locations and have potential to spread innovation, but may face high complexity and limited opportunity for care standardization.

Uncontrolled chemotherapy-induced nausea and vomiting (CINV) can reduce patients’ quality of life and may result in premature discontinuation of chemotherapy. Although nausea and vomiting are commonly grouped together, research has shown that antiemetics are clinically effective against chemotherapy-induced vomiting (CIV) but less so against chemotherapy-induced nausea (CIN). Nausea remains a problem for up to 68% of patients who are prescribed guideline-consistent antiemetics. Despite the high prevalence of CIN, relatively little is known regarding its etiology independent of CIV. In this review paper, we summarize a metagenomics approach to the study and treatment of CIN with the goal of encouraging future research. Metagenomics focuses on genetic risk factors, encompassing both human (i.e., host) and gut microbial genetic variation. Little work to date has focused on metagenomics as a putative biological mechanism of CIN. Metagenomics has the potential to be a powerful tool in advancing scientific understanding of CIN by identifying new biological pathways and intervention targets. Investigation of metagenomics in the context of well-established demographic, clinical, and patient-reported risk factors may help to identify patients at risk and facilitate prevention and management of CIN.

Breast cancer incidence is increasing among Asian Indian and Pakistani women living in the United States. We examined the characteristics of breast cancer in Asian Indian and Pakistani American (AIPA) and non-Hispanic white (NHW) women using data from the surveillance, epidemiology and end results (SEER) program. Breast cancer incidence rates were estimated via segmented Poisson regression using data between 1990 and 2014 from SEER 9 registries, including New Jersey and California. Disease characteristics, treatment and survival information between 2000 and 2016 for 4900 AIPA and 482 250 NHW cases diagnosed after age 18 were obtained from SEER 18 registries and compared using descriptive analyses and multivariable competing risk proportional hazards regression. Breast cancer incidence was lower in AIPA than NHW women, increased with age and the rate of increase declined after age of 46 years. AIPA women were diagnosed at significantly younger age (mean (SD) = 54.5 (13.3) years) than NHW women (mean (SD) = 62 (14) years, P < .0001) and were more likely than NHW cases (P < .0001) to have regional or distant stage, higher grade, estrogen receptor-negative, progesterone receptor-negative, triple-negative or human epidermal growth factor receptor 2-enriched tumors, subcutaneous or total mastectomy, and lower cumulative incidence of death due to breast cancer (hazard ratio = 0.79, 95% CI: 0.72-0.86, P < .0001). AIPA had shorter median follow-up (52 months) than NHW cases (77 months). Breast cancer in AIPA women has unique characteristics that need to be further studied along with a comprehensive evaluation of their follow-up patterns.

Genetic test results have important implications for close family members. Indeterminate negative results are the most common outcome of BRCA1/2 mutation testing. Little is known about family members’ understanding of indeterminate negative BRCA1/2 test results. The purpose of this mixed-methods study was to investigate how daughters and sisters received and understood genetic test results as shared by their mothers or sisters. Participants included 81 women aged 40–74 with mothers or sisters previously diagnosed with breast cancer and who received indeterminate negative BRCA1/2 test results. Participants had never been diagnosed with breast cancer nor received their own genetic testing or counseling. This Institutional Review Board-approved study utilized semi-structured interviews and surveys. Descriptive coding with theme development was used during qualitative analysis. Participants reported low amounts of information shared with them. Most women described test results as negative and incorrectly interpreted the test to mean there was no genetic component to the pattern of cancer in their families. Only seven of 81 women accurately described test results consistent with the meaning of an indeterminate negative. Our findings demonstrate that indeterminate negative genetic test results are not well understood by family members. Lack of understanding may lead to an inability to effectively communicate results to primary care providers and missed opportunities for prevention, screening, and further genetic testing. Future research should evaluate acceptability and feasibility of providing family members letters they can share with their own primary care providers.

Objective Relatives of colorectal cancer (CRC) patients are at increased risk for the disease, yet screening rates still remain low. Guided by the Extended Parallel Process Model, we examined the impact of a personalized, remote risk communication intervention on behavioral intention and colonoscopy uptake in relatives of CRC patients, assessing the original additive model and an alternative model in which each theoretical construct contributes uniquely. Methods We collected intention-to-screen and medical record-verified colonoscopy information on 218 individuals who received the personalized intervention. Results Structural equation modeling showed poor main model fit (root mean square error of approximation (RMSEA) = 0.109; standardized root mean residual (SRMR) = 0.134; comparative fit index (CFI) = 0.797; Akaike information criterion (AIC) = 11,601; Bayesian information criterion (BIC) = 11,884). However, the alternative model (RMSEA = 0.070; SRMR = 0.105; CFI = 0.918; AIC = 11,186; BIC = 11,498) showed good fit. Cancer susceptibility (B = 0.319, p

Background Childhood cancers typically require rigorous treatment at specialized centers in urban areas, which can create substantial challenges for families residing in remote communities. We evaluated the impact of residence and travel time on the burden of care for families of childhood cancer patients. Procedure We conducted a cross-sectional, self-administered survey of 354 caregivers of pediatric cancer patients at a children's hospital serving a seven state area. Measures included the impact of cancer treatment on relocation, employment, schooling, and finances. We evaluated these domains by rural/urban residence and travel time (>1 hour and >2 hours) to the hospital in multivariable regression models. Results Of the 29% of caregivers who reported moving residences as their child was diagnosed, 33% reported that the move was due to their child's cancer. Rural and remote (e.g., >1 hour travel time) caregivers missed more days of work during the first month after diagnosis than did urban and local caregivers, however, these differences did not persist over the first 6 months of therapy. One-third of caregivers reported quitting or changing jobs as a direct result of their child being diagnosed with cancer. Rural respondents had greater out-of-pocket travel expenses and reported a significantly greater perceived financial burden. Rural patients missed more school days and were at an increased risk of having to repeat a grade. Conclusions Childhood cancer has an appreciable impact on the lives of patients and caregivers. The burden is greater for those living far from a treatment center. Pediatr Blood Cancer 2014;61:1918–1924. © 2014 Wiley Periodicals, Inc.

This study was an investigation of awareness, cognitions, and psychosocial and educational needs related to genetic counseling and testing among Latinas and non-Latina whites at increased risk for having a BRCA1/2 mutation. Sixty-three Latina and eighty-four non-Latina white women completed telephone surveys employing a mixture of quantitative and qualitative questions assessing awareness, benefits, risks, barriers, and genetic counseling communication preferences regarding BRCA1/2 testing. Among participants who had not previously had genetic counseling/testing, 56.9% of Latinas (29/51) and 34.8% of non-Latina white participants (24/69) were unaware of the availability of BRCA1/2 testing. In multivariate logistic regression analysis, Latina ethnicity was the only statistically significant independent factor associated with lack of awareness (OR = 0.42; 95% CI = 0.19-0.35). No appreciable differences were noted between ethnic groups regarding perceived benefits of BRCA1/2 testing or desired genetic counseling topics. These findings underscore the importance of increasing awareness of cancer genetic counseling and genetic testing among both Latina and non-Latina white populations.

Objective: This study identifies unique psychosocial characteristics among African American men that put the men at risk for non-adherence to colorectal cancer (CRC) screening (colonoscopy, sigmoidoscopy, and fecal occult blood tests (FOBT)). Subgroups sharing similar psychosocial characteristics may be targeted with specific intervention strategies aimed at increasing participation in screening, which could lead to increased early detection and decreased morbidity and mortality. Methods: The male African American veterans in our sample (n = 260) had a mean age of 57.3 (SD = 7.3) years. Our study employs latent class analysis, a quantitative-based, audience segmentation method to identify homogeneous subgroups of African American men with similar psychosocial characteristics related to CRC screening, potentially in need of different health information and intervention strategies. Latent class regression was used to examine the relationships among latent class structure and demographic characteristics. Results: There were four psychosocial risk classes across the three screening tests. A significant subset of men had psychosocial characteristics indicative of willingness to be screened for each test (colonscopy = 21.8%, sigmoidoscopy = 31.5%, and FOBT = 10.8%), although they were currently non-adherent. Men who received a past screening test, had greater than a high school education, or were married were more likely to be represented in a latent class indicative of being prepared for getting colonoscopy or sigmoidoscopy. Sociodemographic variables were unrelated to FOBT latent class structure. Conclusions: Segmenting our sample of male African American veterans based on psychosocial risk characteristics can inform the development of more precisely targeted interventions for African American men who are non-adherent for CRC screening.

Clinical availability of genetic testing for cancer predisposition genes is generating a major challenge for U.S. health care systems to provide relevant genetic services to underserved populations. Here we present rates of study enrollment and utilization of genetic testing in a research study on BRCA1 testing acceptance in one large kindred. We also present data on baseline access to genetic information as well as enabling and obstructing factors to study enrollment. The study population included female and male members of an African American kindred based in the rural southern United States with an identified BRCA1 mutation. A combination of quantitative and qualitative data were collected and analyzed. Of the 161 living, eligible, and locatable kindred members, 105 (65%) enrolled in the study. Family, personal, and educational motivations were the most commonly endorsed reasons for study participation. The most commonly cited reasons for refusal to participate in the study were: lack of interest, time constraints, and negative experiences with prior participation in genetic research. Eighty three percent of the participants underwent BRCA1 testing. In multiple logistic regression analysis, age 40-49 (odds ratio (OR) = 6.9; 95% confidence interval (CI) = 1.2-39.5), increased perceived risk of being a BRCA1 mutation carrier (OR = 4.1; 95% CI = 1.1-14.6), and high cancer genetics knowledge levels (OR = 1.5; 95% CI = 1.1-2.3) were associated with BRCA1 testing acceptance. The results of this study indicate that cognitive and demographic factors may influence genetic research participation and genetic testing decisions among African Americans who are at increased risk of carrying a deleterious BRCA1 mutation.

Context: Geographic and racial variations in cancer incidence have been observed. Studies of colorectal carcinoma indicate a higher incidence and mortality rate for blacks than for whites in the United States. Purpose: We evaluated the effect of rural versus urban residence on colon cancer risk and stage of disease at diagnosis in blacks and whites. Methods: Interviews were conducted with 558 colon cancer cases and 952 controls enrolled in the North Carolina Colon Cancer Study, a population-based case-control study of blacks and whites residing in 33 contiguous counties. Findings: Residence in a rural area was associated with increased colon cancer risk (odds ratio, 1.4; 95% confidence interval, 1.1-1.8). This association was no longer significant after controlling for recent use of colorectal cancer screening tests (odds ratio, 1.2; 95% confidence interval, 0.9-1.6). Risk estimates were not modified by race nor were they markedly different for extent of disease at diagnosis. However, colorectal cancer screening rates were lower for blacks than for whites. Conclusion: Our findings suggest that rural blacks and whites are at increased risk of colon cancer regardless of stage of disease at diagnosis than their urban counterparts; this relationship may be mediated by screening behavior.

This study investigated uncertainty in individuals undergoing genetic counseling/testing for breast/ovarian cancer susceptibility. Sixty-three individuals from a single kindred with a known BRCA1 mutation rated uncertainty about 12 items on a five-point Likert scale before and 1 month after genetic counseling/testing. Factor analysis identified a five-item total uncertainty scale that was sensitive to changes before and after testing. The items in the scale were related to uncertainty about obtaining health care, positive changes after testing, and coping well with results. The majority of participants (76%) rated reducing uncertainty as an important reason for genetic testing. The importance of reducing uncertainty was stable across time and unrelated to anxiety or demographics. Yet, at baseline, total uncertainty was low and decreased after genetic counseling/testing (P = 0.004). Analysis of individual items showed that after genetic counseling/testing, there was less uncertainty about the participant detecting cancer early (P = 0.005) and coping well with their result (P < 0.001). Our findings support the importance to clients of genetic counseling/testing as a means of reducing uncertainty. Testing may help clients to reduce the uncertainty about items they can control, and it may be important to differentiate the sources of uncertainty that are more or less controllable. Genetic counselors can help clients by providing anticipatory guidance about the role of uncertainty in genetic testing.

BACKGROUND It has been shown that social integration and the availability of social support influence quality of life. However, little is known about the relation between social support and mental and physical health in patients with colorectal cancer. In the current study, the authors examined the effects of social network size, as well as emotional and instrumental support, on health-related quality of life (HRQOL) in patients with colorectal cancer. METHODS Six hundred thirty-six veterans with colorectal cancer were asked to complete a telephone interview, which included a measure of social support (the Berkman–Syme Index) and the Medical Outcomes Study Short Form 12-Item Survey. Mean physical composite scale (PCS) and mental composite scale (MCS) scores were compared across groups. RESULTS No difference in mean PCS or MCS scores was found between patients who had larger social networks and patients who had smaller social networks. The availability of emotional and instrumental support was associated with higher MCS scores, whereas the availability of instrumental support was associated with lower PCS scores. CONCLUSIONS Irrespective of network size, the availability of emotional support and instrumental support had an impact on HRQOL in patients with colorectal cancer. More emphasis needs to be placed on understanding how various types of social support, individually and collectively, influence physical and mental health in patients with colorectal cancer.

BACKGROUND Colorectal carcinoma (CRC) may be the most frequent form of hereditary cancer. Genetic counseling and testing for heritable CRC is a promising approach for reducing the high incidence and mortality rates associated with the disease. Patients with CRC or those with at least one family member with the disease are the most likely persons to request or be offered genetic testing in the clinical or research setting. Currently, however, little is known about the behavioral, psychosocial, ethical, legal, and economic outcomes of CRC genetic counseling and testing. METHODS Eight focus group interviews, four for CRC patients (n = 28) and four for first-degree relatives (n = 33), were conducted to obtain insights into attitudes, beliefs, and informational needs about genetic testing for hereditary CRC. RESULTS Focus group interviews revealed a general lack of knowledge about cancer genetics and genetic testing; worry about confidentiality issues; strong concern for family members, particularly children; and a need for primary care providers to be informed about these issues. Major perceived advantages of genetic testing included improving health-related decisions, guiding physicians in making recommendations for surveillance, and informing relatives about risk potential. Disadvantages included potential discrimination, adverse psychologic effects, and financial costs associated with testing. CONCLUSIONS As knowledge and media coverage of genetics continue to expand, it becomes increasingly important to continue efforts on behalf of, and in partnership with, those individuals most affected by genetic testing for hereditary cancer syndromes. These findings provide data needed to develop and implement informational, educational, counseling, and research-oriented programs that are sensitive to individuals' concerns and preferences.

Purpose: The purpose of this study was to examine risk perceptions and interest in genetic testing among African American and White patients with colorectal cancer. Description of study: In this cross-sectional study, 98 patients with colorectal cancer participated in a brief structured telephone interview. Information was collected on knowledge and risk perceptions regarding colorectal cancer genetics, health behaviors, knowledge about the availability of genetic testing, and interest in genetic testing for colorectal cancer susceptibility. Results: Sixty-one percent of the participants were worried about their relatives' risk of colorectal cancer, and 64% were concerned about being a colorectal cancer susceptibility gene carrier. Although 81% of the participants reported that they had never heard about a genetic test for colorectal cancer susceptibility, 72% stated that they would want to take the test if it were available. Predictors of intention to have a genetic test were younger age, less advanced stage of disease, and more frequent thoughts about colorectal cancer being hereditary. Clinical implications: These results suggest that the demand for genetic testing may be great, despite a general lack of knowledge about colorectal cancer genetics and the potential risks and limitations of testing. Education and counseling about cancer genetics and genetic testing may clarify misconceptions about hereditary colorectal cancer and help patients with colorectal cancer and their family members make informed decisions about whether to undergo testing.

BACKGROUND Sialyl-Tn (STn) represents an aberrantly glycosylated mucin epitope that is expressed in breast carcinoma and other adenocarcinomas and is an important factor in the development of novel immunotherapeutic approaches. The primary aim of the current study was to investigate the influence of STn expression on the prognoses of patients with breast carcinoma. METHODS A cohort of 207 women diagnosed with invasive breast carcinoma who were treated with anthracycline-containing adjuvant chemotherapy and were enrolled in a randomized clinical trial were studied. Expression of STn was determined by an immunohistochemical procedure in which the B72.3 monoclonal antibody was used. Kaplan-Meier and Cox proportional regression survival analyses were used to compare low STn and high STn patients. RESULTS Forty-eight (23%) of the 207 specimens demonstrated high STn staining (>25% cells were immunoreactive). During a median follow-up of 5 years, high STn patients had worse disease free survival than low STn patients (55% vs. 74%, respectively; P = 0.03). High STn expression was significantly associated with age (P = 0.04) but not with other conventional prognostic markers. In multivariate analysis using the Cox regression model, high STn emerged as an independent prognostic indicator for disease free survival (hazard ratio [HR], 2.02; 95% confidence interval [CI], 1.09-3.73) and for overall survival (HR, 2.16; 95% CI, 0.95-4.92). CONCLUSIONS The results of this study suggest that STn may be a valuable marker for identifying women at high risk of developing recurrent breast carcinoma who may be candidates for trials investigating new therapies in combination with standard adjuvant therapy.
