Abstract
PURPOSE Research has shown that racial/ethnic disparities exist in outcomes for colorectal cancer (CRC) patients, but there are no studies assessing inpatient palliative care utilization and hospitalization outcomes in this population. We examined racial/ethnic disparities in palliative care utilization and hospitalization outcomes among CRC and early-onset CRC patients. METHODS Using National Inpatient Sample (NIS) data collected between 2016 and 2018, cross-sectional analyses were performed. Descriptive analyses were done, stratified by race/ethnicity. Multivariable logistic and linear regression models were used to examine racial/ethnic differences in palliative care utilization, inpatient mortality, chemotherapy/radiotherapy use, length of stay and total hospital charges among hospitalized patients with CRC and early-onset CRC. RESULTS Blacks had higher odds (AOR: 1.09; 95% CI: 1.03-1.16) of receiving palliative care consultation while Hispanics had lower odds (AOR: 0.90; 95% CI: 0.84-0.96) compared to Whites. Blacks had 1.1 times higher odds (95% CI: 1.01-1.18) of inpatient mortality relative to Whites while Hispanics had 16% (AOR: 0.84; 95% CI: 0.76-0.93) lower odds of inpatient mortality. Compared to Whites, Blacks (AOR: 1.99; 95% CI: 1.64-2.41), Hispanics (AOR: 2.49; 95% CI: 1.94-3.19) and colorectal cancer patients in the other category (AOR: 1.72; 95% CI: 1.35-2.18) were more likely to receive inpatient treatment with chemotherapy/radiotherapy. Furthermore, Black patients were 1.1 times (95% CI: 1.06-1.14) more likely to have a length of stay more than 5 days. Blacks (𝛃: $3,096.7; 95% CI: $1,207.0-$4,986.5) Hispanic (𝛃: $10,237.5; 95% CI: $7,558.2-$12,916.8) and other patients (𝛃: $6,332.0; 95% CI: $2,830.9-$9, 833.2) had higher hospital charges relative to their White counterparts. Among patients with early onset CRC, Blacks had higher palliative care use (AOR: 1.29; 95% CI: 1.10-1.51) and inpatient mortality (AOR: 1.38; 95% CI: 1.06-1.79) while Hispanics reported $5,589.7 (95% CI: $683.2-$10,496.2) higher total hospital charges and were more likely to receive inpatient chemotherapy/radiotherapy (AOR: 2.48; 95% CI: 1.70-3.63). CONCLUSION Further research is needed to explore specific cultural, socioeconomic, and political factors that explain these disparities and identify ways to narrow the gap. Meanwhile, the healthcare sector will need to assess what strategies might be helpful in addressing these disparities in outcomes in the context of other socioeconomic and cultural factors that may be affecting the patients.

Abstract
BACKGROUND: Novel agents (NAs) (ibrutinib, idelalisib, and venetoclax) were first introduced in 2013 as therapeutic options to treat chronic lymphocytic leukemia (CLL). OBJECTIVES: To determine if the uptake of NAs for first-line treatment was similar in Black and White patients with CLL treated in the Department of Veterans Affairs (VA). METHODS: We conducted a retrospective cohort study including adults with CLL managed in the VA from October 1, 2013, to September 30, 2017. Descriptive statistics were used to summarize demographic data, and appropriate bivariable statistical tests were used to compare NA use, baseline characteristics, health outcomes, and complications. A multivariable logistic regression model was used to identify factors associated with uptake of NAs. The study included 565 patients; 86% were White and 14% were Black. Black patients were younger than White patients (median age [66 vs 69 years; P < 0.01]) but had similar median baseline Charlson comorbidity scores (4 vs 5). RESULTS: Overall, Black patients were less likely to receive NAs than White patients (14% vs 26%; P = 0.02). The gap narrowed over the study period: 4% vs 17% (2014), 13% vs 25% (2015), 17% vs 33% (2016), and 31% vs 33% (2017). Black race (P = 0.02) and fiscal year (P < 0.01) were the only variables significantly associated with NA use in the multivariable model. Health outcomes and most complications were similar for Black and White patients despite the difference in prescribing patterns. CONCLUSIONS: This is the first study to identify a potential health disparity with respect to use of NAs among Black and White patients with CLL treated in the VA. Fortunately, health outcomes and most complications were similar for Black and White patients despite the difference in prescribing patterns. DISCLOSURES: Funding for the study was provided by AstraZeneca as a research grant to the Foundation for Advancing Veterans' Health Research (FAVHR), a non-profit entity within the Audie L. Murphy Veterans Hospital, San Antonio, TX. Drs Nooruddin and Frei have received research grants (paid to FAVHR) from AstraZeneca in the last 3 years. Ms Ryan is an employee of AstraZeneca.

Abstract
Health care disparities are defined as health differences between groups that are avoidable, unnecessary, and unjust. Racial disparities in colorectal cancer mortality, particularly for Black patients, are well-described. Disparities in preventative measures, early detection, effective treatment, and posttreatment services contribute to these differences. Underlying these issues are patient, provider, health care system, and policy-level factors that lead to these disparities. Multilevel interventions designed to address each level of care can provide an effective means to mitigate these disparities.

Abstract
Background The impact of socioeconomic status (SES) has been described for screening and accessing treatment for colon cancer. However, little is known about the “downstream” effect in patients who receive guideline‐concordant treatment. This study assessed the impact of SES on cancer‐specific survival (CSS) and overall survival (OS) for stage III colon cancer patients. Methods The SEER Census Tract‐Level SES Dataset from 2004 to 2015 was used to identify stage III colon adenocarcinoma patients who received curative‐intent surgery and adjuvant chemotherapy. The predictor variable was census tract SES. SES was analyzed as quintiles. The outcome variables were OR and CSS. Statistical analysis included chi square tests for association, Kaplan–Meier, Cox, Fine and Gray regression for survival analysis. Results In total, 27,222 patients met inclusion criteria. Lower SES was associated with younger age, Black or Hispanic race/ethnicity, Medicaid/uninsured, higher T stage, and lower grade tumors. CSS at the 25th percentile was 54 months for the lowest SES quintile and 80 for the highest. Median OS was 113 months for the lowest SES quintile and not reached for highest. The 5‐year CSS rate was 72.4% for the lowest SES quintile compared to 78.9% in the highest (p < 0.001). The 5‐year OS rate was 66.5% for the lowest SES quintile and 74.6% in the highest (p < 0.001). Conclusion This is the first study to evaluate CSS and OS in an incidence‐based cohort of stage III colon cancer patients using a granular, standardized measure of SES. Despite receipt of guideline‐based treatment, SES was associated with disparities in CSS and OS.

Abstract
Background Disparities in colon cancer outcomes have been reported across race and socioeconomic status, which may reflect, in part, access to care. We sought to assess the influences of race and median household income (MHI) on outcomes among colon cancer patients with similar access to care. Methods We conducted a prospective, observational study of 1206 stage III colon cancer patients enrolled in the CALGB 89803 randomized adjuvant chemotherapy trial. Race was self-reported by 1116 White and 90 Black patients at study enrollment; MHI was determined by matching 973 patients’ home zip codes with publicly available US Census 2000 data. Multivariate analyses were adjusted for baseline sociodemographic, clinical, dietary, and lifestyle factors. All statistical tests were 2-sided. Results Over a median follow-up of 7.7 years, the adjusted hazard ratios for Blacks (compared with Whites) were 0.94 (95% confidence interval [CI] = 0.66 to 1.35, P = .75) for disease-free survival, 0.91 (95% CI = 0.62 to 1.35, P = .65) for recurrence-free survival, and 1.07 (95% CI = 0.73 to 1.57, P = .73) for overall survival. Relative to patients in the highest MHI quartile, the adjusted hazard ratios for patients in the lowest quartile were 0.90 (95% CI = 0.67 to 1.19, Ptrend = .18) for disease-free survival, 0.89 (95% CI = 0.66 to 1.22, Ptrend = .14) for recurrence-free survival, and 0.87 (95% CI = 0.63 to 1.19, Ptrend = .23) for overall survival. Conclusions In this study of patients with similar health-care access, no statistically significant differences in outcomes were found by race or MHI. The substantial gaps in outcomes previously observed by race and MHI may not be rooted in differences in tumor biology but rather in access to quality care.

Abstract
Colorectal cancer (CRC) is the third most common cancer in men and women in the United States. CRC screening efforts are directed toward removal of adenomas and sessile serrated lesions and detection of early-stage CRC. The purpose of this article is to update the 2009 American College of Gastroenterology CRC screening guidelines. The guideline is framed around several key questions. We conducted a comprehensive literature search to include studies through October 2020. The inclusion criteria were studies of any design with men and women age 40 years and older. Detailed recommendations for CRC screening in average-risk individuals and those with a family history of CRC are discussed. We also provide recommendations on the role of aspirin for chemoprevention, quality indicators for colonoscopy, approaches to organized CRC screening and improving adherence to CRC screening. CRC screening must be optimized to allow effective and sustained reduction of CRC incidence and mortality. This can be accomplished by achieving high rates of adherence, quality monitoring and improvement, following evidence-based guidelines, and removing barriers through the spectrum of care from noninvasive screening tests to screening and diagnostic colonoscopy. The development of cost-effective, highly accurate, noninvasive modalities associated with improved overall adherence to the screening process is also a desirable goal.

Abstract
IFamily members of individuals with colorectal cancer (CRC) may be at increased risk of developing the disease. However, the majority of CRC can be prevented through colonoscopy screening and family members may not be aware if they are recommended to pursue earlier screening because of their family history of CRC. As such, tools must be developed to effectively communicate potential changes to the recommended age for colonoscopy screening and other important CRC-related information to family members. We modified and adapted a successful intervention for families with melanoma to be appropriate for families with CRC to increase communication and screening in family members. The multistep process included the following: (1) developing a paper version of the intervention, (2) piloting the paper version among families with CRC, (3) developing the web-based version, and (4) testing the intervention for usability. Qualitative data was collected and analyzed for pilot testing. Usability testing utilized both qualitative and quantitative data. Patients with CRC liked the paper version and had multiple suggestions, including adding a better introduction, sections on genetics and family history, and clearer communication assistance. The web-based tool was well received and improved upon the linear book format with links, better section instructions, and more proactive communication tools for families. These processes produced materials that satisfied individuals from various families with assistance and support for communicating about CRC. Evaluating the effects of the tools in rigorous research projects is the next step.

Abstract
BACKGROUND Non-Hispanic blacks (NHB) and Hispanics often present with advanced colorectal cancer (CRC). The aim of the study was to characterize CRC differences among Hispanics, NHB, and non-Hispanic whites (NHW). METHODS A cross-sectional analysis and logistic regression of 2009 Florida Agency for Healthcare Administration Hospital Admission Database data for CRC using the International Classification of Diseases, 9th Revision, Clinical Modification codes was performed. Outcomes included CRC location, frequency of metastasis and colectomy rates. Each minority group was compared with NHW. RESULTS A total of 34,577 patients were NHW, 5190 were NHB, and 5033 were Hispanic. NHB had more proximal CRC [odds ratio (OR), 1.17; 95% confidence interval (CI), 1.09-1.25; P<0.0001]; Hispanics had more distal CRC (OR, 0.90; 95% CI, 0.83-0.96; P=0.0024). Hispanics had increased metastases (OR, 1.11; 95% CI, 1.02-1.22; P=0.04). NHB and Hispanics underwent fewer colectomies [(OR, 0.93; 95% CI, 0.86-0.99; P=0.03) and (OR, 0.9; 95% CI, 0.84-0.97; P=0.001), respectively]. CONCLUSIONS Disparities in CRC metastases and colectomy rates exist among these racial groups in Florida. This work should serve as a foundation to study potential causes and to design culture-specific interventions.

Abstract
BACKGROUND No studies have investigated whether race/ethnicity is associated with the recommended use of preoperative chemotherapy or subsequent outcomes in gastric cancer. To determine whether there is such an association, analyses of patients with gastric cancer in the National Cancer Data Base (NCDB) were performed. METHODS Patients with clinical T2-4bN0-1M0 gastric adenocarcinoma, as defined by the eighth edition of the American Joint Committee on Cancer staging manual, who underwent gastrectomy from 2006 to 2014 were identified from the NCDB. Multiple logistic regression was conducted to examine factors associated with preoperative chemotherapy use. RESULTS This study identified 16,945 patients who met the criteria, and 8286 of these patients (49%) underwent preoperative chemotherapy. The use of preoperative chemotherapy remarkably increased over the study period, from 34% in 2006 to 65% in 2014. Preoperative chemotherapy was more commonly used for cardia tumors than noncardia tumors (83% vs 44% in 2014). In a multivariable analysis, races and ethnicities other than non-Hispanic (NH) white race were associated with less frequent use of preoperative chemotherapy in comparison with NH whites after adjustments for social, tumor, and hospital factors. The insurance status and the education level mediated an enhanced effect of racial/ethnic disparities in preoperative chemotherapy use. The use of preoperative chemotherapy and radiation therapy was associated with reduced racial/ethnic disparities in overall survival. CONCLUSIONS Racial/ethnic disparities in the use of preoperative chemotherapy and in outcomes exist among patients with gastric cancer in the United States. Efforts to improve the access to high-quality cancer care in minority groups may reduce racial disparities in gastric cancer in the United States.

Abstract
OBJECTIVE To assess recent trends of administering adjuvant gemcitabine-docetaxel (GD) chemotherapy for Stage I uterine leiomyosarcoma, and to compare disease-free and overall survival between women who received and did not receive adjuvant GD chemotherapy. METHODS All patients diagnosed with Stage I uterine leiomyosarcoma in a California-Colorado population-based health plan inclusive of 2006-2013 were included in a retrospective cohort. Adjuvant GD chemotherapy rates, clinico-pathologic characteristics and survival estimates were assessed. RESULTS Of 111 women with Stage I uterine leiomyosarcoma, 33 received adjuvant GD (median 4cycles), 77 received no chemotherapy, and 1 patient excluded for non-GD chemotherapy. GD-chemotherapy and no-chemotherapy groups were similar with respect to age, stage (IA/IB), uterine weight, mitotic index, body mass index, and Charlson comorbidity score. Non-Hispanic white women were twice as likely to receive adjuvant chemotherapy as non-white or Hispanic women (37.7 vs. 17.1%, P=0.02). The proportion of women receiving adjuvant GD chemotherapy increased from 6.5% in 2006-2008 to 46.9% in 2009-2013 (P<0.001). There was no significance difference in unadjusted Kaplan-Meyer estimated disease-free (P=0.95) or overall survival (P=0.43) between GD-chemotherapy and no-chemotherapy cohorts. Corresponding adjusted Cox proportional hazard ratios for adjuvant GD chemotherapy compared to no chemotherapy were 1.01 (95% confidence interval [CI] 0.57-1.80, P=0.97) for recurrence and 1.28 (95% CI 0.69-2.36, P-0.48) for mortality. CONCLUSIONS Use of adjuvant GD chemotherapy for Stage I uterine leiomyosarcoma has increased significantly in the last decade, despite unclear benefit. Compared to no chemotherapy, 4-6cycles of adjuvant GD chemotherapy does not appear to alter survival outcomes.

Abstract
BACKGROUND While racial disparity in colorectal cancer survival have previously been studied, whether this disparity exists in patients with metastatic colorectal cancer receiving care at safety net hospitals (and therefore of similar socioeconomic status) is poorly understood. METHODS We examined racial differences in survival in a cohort of patients with stage IV colorectal cancer treated at the largest safety net hospital in the New England region, which serves a population with a majority (65%) of non-Caucasian patients. Data was extracted from the hospital's electronic medical record. Survival differences among different racial and ethnic groups were examined graphically using Kaplan-Meier analysis. A univariate cox proportional hazards model and a multivariable adjusted model were generated. RESULTS Black patients had significantly lower overall survival compared to White patients, with median overall survival of 1.9 years and 2.5 years respectively. In a multivariate analysis, Black race posed a significant hazard (HR 1.70, CI 1.01-2.90, p=0.0467) for death. Though response to therapy emerged as a strong predictor of survival (HR=0.4, CI=0.2-0.7, p=0.0021), it was comparable between Blacks and Whites. CONCLUSIONS Despite presumed equal access to healthcare and socioeconomic status within a safety-net hospital system, our results reinforce findings from previous studies showing lower colorectal cancer survival in Black patients, and also point to the importance of investigating other factors such as genetic and pathologic differences.

Abstract
Whether defined by race, ethnicity, or socioeconomic status, there are clear health disparities in colon cancer-disparities that exist whether you measure screening, incidence, or mortality. Rather than rehash disparity statistics, the purpose of this educational article is to highlight important resources and how they can be used to help narrow these disparities. Although the logistics can be complex, the general solutions to eliminating colon cancer health disparities are not complex. They are as follows: Asymptomatic persons need to be screened. After being screened, they need to be diagnosed. After being diagnosed, they need to receive appropriate treatment in a timely fashion. After receiving treatment, they have to receive appropriate follow-up and information and advice on lifestyle changes. If we can implement these measures, then cancer-specific mortality disparities will be dramatically reduced, if not eliminated.

Abstract
In the 2010 Census, just over one-third of the United States (US) population identified themselves as being something other than being non-Hispanic white alone. This group has increased in size from 86.9 million in 2000 to 111.9 million in 2010, representing an increase of 29 percent over the ten year period. Per the American Cancer Society, racial and ethnic minorities are more likely to develop cancer and die from it when compared to the general population of the United States. This is particularly true for colorectal cancer (CRC). The primary aim of this review is to highlight the disparities in CRC among racial and ethnic minorities in the United States. Despite overall rates of CRC decreasing nationally and within certain racial and ethnic minorities in the US, there continue to be disparities in incidence and mortality when compared to non-Hispanic whites. The disparities in CRC incidence and mortality are related to certain areas of deficiency such as knowledge of family history, access to care obstacles, impact of migration on CRC and paucity of clinical data. These areas of deficiency limit understanding of CRC's impact in these groups and when developing interventions to close the disparity gap. Even with the implementation of the Patient Protection and Affordable Healthcare Act, disparities in CRC screening will continue to exist until specific interventions are implemented in the context of each of racial and ethnic group. Racial and ethnic minorities cannot be viewed as one monolithic group, rather as different segments since there are variations in incidence and mortality based on natural history of CRC development impacted by gender, ethnicity group, nationality, access, as well as migration and socioeconomic status. Progress has been made overall, but there is much work to be done.

Abstract
INTRODUCTION Contralateral prophylactic mastectomy (CPM) is an option for women who wish to reduce their risk of breast cancer or its local recurrence. There is limited data on demographic differences among patients who choose to undergo this procedure. METHODS The population-based Florida cancer registry, Florida's Agency for Health Care Administration data, and US census data were linked and queried for patients diagnosed with invasive breast cancer from 1996 to 2009. The main outcome variable was the rate of CPM. Primary predictors were race, ethnicity, socioeconomic status (SES), marital status and insurance status. RESULTS Our population was 91.1% White and 7.5% Black; 89.1% non-Hispanic and 10.9% Hispanic. Out of 21,608 patients with a single unilateral invasive breast cancer lesion, 837 (3.9%) underwent CPM. Significantly more White than Black (3.9% vs 2.8%; P<0.001) and more Hispanic than non-Hispanic (4.5% vs 3.8%; P=0.0909) underwent CPM. Those in the highest SES category had higher rates of CPM compared to the lowest SES category (5.3% vs 2.9%; P<0.001). In multivariate analyses, Blacks compared to Whites (OR =0.59, 95% CI =0.42-0.83, P=0.002) and uninsured patients compared to privately insured (OR =0.60, 95% CI =0.36-0.98, P=0.043) had significantly less CPM. CONCLUSION CPM rates were significantly different among patients of different race, socio-economic class, and insurance coverage. This observation is not accounted for by population distribution, incidence or disease stage. More in-depth study of the causes of these disparities in health care choice and delivery is critically needed.

Abstract
Current prognostic models for peripheral T-cell lymphoma (PTCL) have multiple limitations, and questions exist regarding applicability to current patients. We utilized the Surveillance Epidemiology and End Results (SEER)-18 database to evaluate factors affecting overall survival (OS) of PTCL in the modern era and identified 8802 patients between 2000-2010. Most subtypes of PTCL increased in incidence during the study period. In univariate analyses, age >55 years, black race, advanced stage, absence of extra-nodal disease, omission of radiation therapy (RT) and high-risk histology each predicted inferior OS (P < 0·0001). Multivariate analysis (MVA) demonstrated that hepatosplenic, enteropathy-associated and extra-nodal Natural Killer/T cell histologies, each had hazard ratios >1·5 (P ≤ 0·0001) for death. Further, age ≥55 years, black race and advanced stage maintained their significance in the MVA (P < 0·0001 each). Based on the significant factors, a prognostic model was constructed and subsequently validated in an independent cohort. The new model incorporated age, stage, histology and race, with an OS ranging from 9 months (highest risk group) to 120 months (lowest risk group). In summary, this is the largest study of PTCL patients in the modern era that provides risk stratification utilizing a new prognostic model that can be incorporated into future prospective clinical trials.

Abstract
BACKGROUND African American women present with more aggressive breast tumors and at later stages than white women. Many factors have been proposed to explain these findings, including socioeconomic status, cultural beliefs, and access to medical care. The purpose of this project was to determine if stage at presentation would be equivalent in a system providing equal access to care and if screening was equivalent. METHODS The Naval Medical Center San Diego (NMCSD) tumor registry from 2007 to 2012 was queried for this cross-sectional study. Eligible women included all those diagnosed and treated for breast cancer at NMCSD. Distribution of tumor stage (early vs. advanced) between racial groups was compared by age, treatment, and receptor status. RESULTS A total of 624 women were eligible; 88 % were early stage (0-II) and 12 % presented with advanced stage (III or IV). Racial differences in distribution were significant among African American and Hispanic women for early versus advanced presentation (p = 0.011). No racial disparity was seen in screening patterns among women. CONCLUSIONS In a military health system with equal access to care and standard screening recommendations, screening patterns did not vary with race but did vary with stage and active duty status. African American women present with breast cancer at later stages and with more hormone-receptor negative tumors, suggesting that biology rather than socioeconomic or access factors may be the most important determinant of stage at presentation of breast cancer for African American women.

Abstract
Colorectal cancer (CRC) is the second leading cause of cancer related deaths in the United States. There are significant differences in CRC incidence and mortality by race with the highest burden occurring among blacks. The underlying factors contributing to CRC disparities are multiple and complex. Studies have suggested that a higher prevalence of putative risk factors for CRC, limited access to healthcare services, lower utilization of healthcare resources and increased biological susceptibilities contribute to this disparity by race. This article reviews the factors associated with the disproportionally higher burden of CRC among blacks; addresses the controversies regarding the age to begin CRC screening and the screening modality to use for blacks; and proffers solutions to eliminate CRC disparity by race.

Abstract
SUMMARY While treatment for colorectal cancer has evolved significantly over the past 10 years with the introduction of active chemotherapeutic agents and targeted therapies, this has been at the cost of increased toxicity for patients; and significant financial burden for governments and patients. Predicting clinical outcomes, especially given the largely elderly patient population involved, is therefore paramount. This review seeks to summarize existing data regarding the prediction of response and toxicity to chemotherapy agents currently used in the treatment of colorectal cancer.

Abstract
BACKGROUND Racial disparities in colorectal cancer persist. Late stage at presentation and lack of stage-specific treatment may be contributing factors. We sought to evaluate the magnitude of disparity remaining after accounting for gender, stage, and treatment using predicted survival models. METHODS We used institutional tumor registries from a public health system (two hospitals) and a not-for-profit health system (nine hospitals) from 1995 to 2011. Demographics, stage at diagnosis, treatment, and survival were recorded. Hazard ratios (HRs) and predicted HRs were determined by Cox regression and postestimation analyses. RESULTS There were 6,990 patients: 55.7 % white, 23.6 % African American, 15.1 % Hispanic, and 5.6 % Asian/other. Predictors of survival were surgery (HR 0.57, 95 % confidence interval [CI] 0.46-0.70), chemotherapy (HR 0.7, 95 % CI 0.62-0.79), female gender (HR 0.87, 95 % CI 0.83-0.90), age (HR 1.04, 95 % CI 1.03-1.05), and African American race (HR 3.6, 95 % CI 1.5-8.4). Balancing for stage, gender, and treatment reduced the predicted HRs for African Americans by 28 % and Hispanics by 17 %. In this model, African American and Hispanics still had the worst predicted HRs at younger ages, but whites had the worst predicted HR after age 75. CONCLUSIONS Gender, stage, and treatment partially accounted for worsened survival in African Americans and Hispanics at all ages. At younger ages, race-related disparities remained which may reflect tumor biology or other unknown factors. Once gender, stage, and treatment are balanced at older ages, the increased mortality observed in whites may be due to factors such as comorbidities. Further system- and patient-level study is needed to investigate reasons for colorectal cancer survival disparities.

Abstract
BACKGROUND Few studies have evaluated disparities of race and socioeconomic status (SES) with outcomes in patients with rectal cancer. We hypothesize that disparities exist in the treatment and outcomes among patients with rectal cancer. METHODS Medical records of all patients with rectal cancer treated from 2000 to 2009 at an NCI cancer center (Fox Chase Cancer Center) and an urban academic center (Temple University Hospital) were retrospectively reviewed from a prospectively maintained tumor registry database. SES was estimated using census data. Quartiles of income and education based on zip codes were calculated. Lowest vs other quartiles were compared. Clinicopathologic variables included: initial stage, chemotherapy refusal, sphincter preservation, and overall survival (OS). RESULTS A total of 748 patients were included in the analysis (581 white, 135 black, 6 other, 26 unknown). No difference in race, SES, or insurance status was seen with regard to stage at presentation. Chemotherapy and radiation refusal was rare. After excluding stage IV patients; sphincter preservation was more common among those with higher income. Median OS for all stages was worse for nonwhite patients (31 vs 50 months, p < .001), and those with low income and education. OS disparities were most pronounced among nonwhite patients with advanced disease. Insurance was not associated with a survival difference. Age, stage, and race were independent predictors of survival. CONCLUSIONS Disparity exists in outcomes of patients with rectal cancer. Nonwhite race is associated with worse OS, and lower SES is associated with lower OS and sphincter preservation among patients with rectal cancer.

METHODS From 2003 to 2009, 2281 community members participated in CBPPs conducted by the Beaumont Cancer Institute in cooperation with the Arab American and Chaldean (AAC) Council, the National Cancer Institute, and the American Cancer Society. The study population consisted of 1067 individuals who completed a postcancer forum survey: 642 from the African American (AA) and 425 from the AAC forums. Data were collected on participants' screening history and participation in subsequent screening tests after the previous year's CBPP. RESULTS Following attendance of at least one cancer forum the previous year, 329 (30.8%) of the 1067 participant respondents underwent some type of cancer screening, 32% in the AA forums and 28.9% in the AAC forums. Compared with published controls, the CBPPs led to a 38.6% increase in mammographic screening and a 28.7% increase in prostate-specific antigen screening; the AA cohort had 39.7% and 28.4% increases whereas the AAC cohort had 36.3% and 28.9% increases in mammographic and prostate-specific antigen screening, respectively. CONCLUSIONS The results of this study suggest that implementing CBPPs are feasible in underscreened ethnic minority populations. Further studies need to be performed to determine the absolute benefit of CBPPs compared with baseline levels of screening within these ethnic minority populations.

Abstract
Despite a profusion of studies over the past several years documenting racial differences in cancer outcomes, there is a paucity of data as to the root causes underlying these observations. This article reviews work to date focusing on black-white differences in cancer outcomes, explores potential mechanisms underlying these differences, and identifies patient, physician, and health care system factors that may account for persistent racial disparities in cancer care. Research strategies to elucidate the relative influence of these various factors and policy recommendations to reduce persistent disparities are also discussed.

Abstract
BACKGROUND Among patients with resected colon cancer, black patients have worse survival than whites. We investigated whether disparities in survival and related endpoints would persist when patients were treated with identical therapies in controlled clinical trials. METHODS We assessed 14,611 patients (1218 black and 13,393 white) who received standardized adjuvant treatment in 12 randomized controlled clinical trials conducted in North America for resected stage II and stage III colon cancer between 1977 and 2002. Individual patient data on covariates and outcomes were extracted from the Adjuvant Colon Cancer ENdpoinTs (ACCENT) database. The endpoints examined in this meta-analysis were overall survival (time to death), recurrence-free survival (time to recurrence or death), and recurrence-free interval (time to recurrence). Cox models were stratified by study and controlled for sex, stage, age, and treatment to determine the effect of race. Kaplan-Meier estimates were adjusted for similar covariates to control for confounding. All statistical tests were two-sided. RESULTS Black patients were younger than whites (median age, 58 vs 61 years, respectively; P < .001) and more likely to be female (55% vs 45%, respectively; P < .001). Overall survival was worse in black patients than whites (hazard ratio [HR] of death = 1.22, 95% confidence interval [CI] = 1.11 to 1.34, P < .001). Five-year overall survival rates for blacks and whites were 68.2% and 72.8%, respectively. When subsets defined by sex, stage, and age were analyzed, overall survival was consistently worse in black patients. Recurrence-free survival was worse in black patients than whites (HR of recurrence or death = 1.14, 95% CI = 1.04 to 1.24, P = .0045). Three-year recurrence-free survival rates in blacks and whites were 68.4% and 72.1%, respectively. In contrast, recurrence-free interval was similar in black and white patients (HR of recurrence = 1.08, 95% CI = 0.97 to 1.19, P = .15). Three-year recurrence-free interval rates in blacks and whites were 71.3% and 74.2%, respectively. CONCLUSIONS Black patients with resected stage II and stage III colon cancer who were treated with the same therapy as white patients experienced worse overall and recurrence-free survival, but similar recurrence-free interval, compared with white patients. The differences in survival may be mostly because of factors unrelated to the patients' adjuvant colon cancer treatment.

Abstract
BACKGROUND African Americans are more likely to be diagnosed with metastatic colorectal cancer than whites and have shorter survival once they are diagnosed. In this analysis, the authors examined racial differences in clinical outcomes among patients with metastatic colorectal cancer (mCRC) who received bevacizumab. METHODS The study cohort consisted of 1589 white patients (81.4%) and 227 African American patients (11.6%) with mCRC who received front-line bevacizumab therapy and who were enrolled in a large, predominantly community-based, prospective, observational cohort study. Differences in time-to-event endpoints and response rates were examined by race. Differences in the incidence of baseline and treatment-related toxicities associated with bevacizumab also were examined. Finally, differences in patterns of care by race were explored. RESULTS The median overall survival was 22.6 months for African Americans and 22.9 months for whites, and the median progression-free survival was 9.5 months for African Americans and 9.8 months for whites. Response rates (complete responses plus partial responses) were 37.5% for African Americans and 46.3% for whites (adjusted odds ratio, 0.67; 95% confidence interval, 0.50-0.90). African Americans had higher rates of baseline diabetes (18.9% vs 11%; P = .002), higher rates of hypertension (52.9% vs 41.4%; P = .001), and worsening hypertension while on therapy (13.7% vs 8.9%; P = .02), but no differences in on-treatment arterial thromboembolic events were observed. CONCLUSIONS This large observational cohort study of patients with mCRC demonstrated that, when treated in a similar fashion with modern chemotherapy, African Americans and whites had equivalent cancer outcomes. No significant differences in bevacizumab-related toxicity or patterns of care were observed between African Americans and whites. The lower response rate among African Americans deserves further study.

Abstract
OBJECTIVES Studies have reported potential underuse of surgical resection in black patients with nonmetastatic colorectal cancer. Our objective was to determine the independent, adverse effect of race on surgical resection, controlling for tumor location, comorbidity, and socioeconomic/insurance status. METHODS All cases of nonmetastatic colon/rectal cancer reported to our state's Central Cancer Registry from 1996 to 2002 were identified and linked to Inpatient/Outpatient Surgery Files and the 2000 Census. Comorbidity (Deyo-Charlson Index) was calculated using ICD-9-CM codes and educational level/income were estimated at the zip code level. Characteristics between whites and blacks were compared using [chi]2 tests. Odds ratios (OR) of resection were calculated using logistic regression analysis. RESULTS We identified 5590/1932 white and 1906/466 black patients with colon/rectal cancer. Blacks were more likely to be younger, not married, rural, less educated, live in poverty, and uninsured/covered by Medicaid compared with whites (all P < 0.001). Underuse of surgery was far greater among blacks with rectal cancer (82.0% vs. 89.3% in whites, P< 0.001) compared with blacks with colon cancer (92.9% vs. 94.5% in whites, P < 0.001). After controlling for comorbidity/socioeconomic/insurance status and tumor location, the adjusted OR (95% CI) for resection for blacks with colon cancer and blacks with rectal cancer living in poverty were 0.67 (0.51–0.88) and 0.20 (0.07–0.57), respectively. CONCLUSIONS Black race is a powerful, independent predictor of underuse of surgery in rectal cancer patients living in poverty. It is incumbent on the gastroenterology/surgical community to determine whether misperceptions about rectal surgery or barriers to successfully navigating multidisciplinary, rectal cancer care may account for these disparities.

Abstract
PURPOSE To investigate the effectiveness of a screening tool to enhance clinical trial participation at a community radiation oncology center involved in a National Cancer Institute-funded disparities program but lacking on-site clinical trials personnel. PATIENTS AND METHODS The screening form was pasted to the front of the charts and filled out for all new patients over the 9-month period of the study, during which time five external beam radiation therapy (EBRT) trials and a patient perception study were open for accrual. Patient consent was obtained by assorted personnel at several different sites. Patients potentially eligible for a trial were identified and approached by one of the clinic staff. Patients who were under- or uninsured, age > 80 years, members of an racial/ethnic minority, or recipients of medical assistance were identified as at risk for health care disparities and were offered patient navigator services. RESULTS Of 196 patients consulted during the study, 144 were treated with EBRT. Of the 24 patients eligible for EBRT trials, 23 were approached (one had an incomplete screening form), and 15 accepted. Of 77 patients eligible for a patient perception trial, 72 were approached (five had incomplete forms), and 45 accepted. The eligibility and acceptance rates for EBRT trials were similar for disparities and nondisparities patients. Screening was completed for 96 patients (67%). CONCLUSION When completed, the screening tool ensured clinical trial accrual. The major factor limiting overall accrual was a shortage of available trials.

Abstract
Cancer incidence and mortality rates show great variations across nations and between population groups. These variations are largely explained by differences in age distribution, diet and lifestyle, access to health care, cultural barriers and exposure to carcinogens and pathogens. Cancers caused by infections are significantly more common in developing than developed countries, and they overproportionally affect immigrant populations in the USA and other countries. The global pattern of cancer is not stagnant. Instead, it is dynamic because of fluctuations in the age distribution of populations, improvements in cancer prevention and early detection in affluent countries and rapid changes in diet and lifestyle in parts of the world. For example, increased smoking rates have caused tobacco-induced cancers to rise in various Asian countries, whereas reduced smoking rates have caused these cancers to plateau or even begin to decline in Western Europe and North America. Some population groups experience a disproportionally high cancer burden. In the USA and the Caribbean, cancer incidence and mortality rates are excessively high in populations of African ancestry when compared with other population groups. The causes of this disparity are multifaceted and may include tumor biological and genetic factors and their interaction with the environment. In this review, we will discuss the magnitude and causes of global cancer health disparities and will, with a focus on African-Americans and selected cancer sites, evaluate the evidence that genetic and tumor biological factors contribute to existing cancer incidence and outcome differences among population groups in the USA.

Abstract
The purpose of this study is to determine the association between ethnicity and lymph node retrieval after colon cancer resection. Using the Surveillance Epidemiology and End Results (SEER)-Medicare database, patients who underwent colon cancer resection from 2000-2003 were evaluated. Subjects were classified as having <12 (N = 20,605) or ≥12 (N = 12,358) lymph nodes examined. Multivariate models were used to analyze the relationship between lymph nodes resected and independent variables. Out of a total of 32,936 patients, 62.5% had fewer than 12 lymph nodes resected. In multivariate analysis, Hispanic ethnicity was associated with a significantly lower chance of having ≥12 lymph nodes than the Caucasian population (OR = 0.61; CI, 0.50-0.74). Despite this, there was no understaging: the proportion of stage II and III diagnoses was the same. Both groups received the same rate of cancer-directed surgery and survival was equivalent. During this study period, a majority of colon cancer resections were inadequate based on the current standard of ≥12 nodes. Hispanic patients were less likely to have an adequate node resection when compared to Caucasians. Despite fewer lymph nodes harvested, they had equivalent staging and survival. These results suggest that ethnicity influences the lymph node count.

Abstract
Colorectal cancer (CRC) treatment has evolved significantly over the last ten years with the use of active chemotherapeutic agents including fluoropyrimidines, oxaliplatin and irinotecan plus targeted monoclonal antibodies bevacizumab, cetuximab and panitumumab. The addition of newer chemotherapeutic agents and targeted therapies has improved patient outcomes at the cost of increased toxicity with not all patients benefiting from these treatments. It is necessary for clinicians to more accurately predict clinical outcomes particularly in the predominantly elderly CRC patient population. This review aims to summarise existing data regarding the use of clinical and laboratory variables plus molecular markers in predicting response, survival and toxicity to chemotherapy agents and targeted monoclonal antibodies currently used in the treatment of CRC.

Abstract
BACKGROUND The pathologic identification of 12 or more lymph nodes (LN) after colectomy for colon cancer became a quality indicator for surgery in 2001. We investigated whether this new standard of care was differentially adopted across racial and socioeconomic lines. METHODS We identified 111,339 stage I to III colon cancer patients identified as black or white in the Surveillance, Epidemiology, and End Results database from 1988 to 2004 who underwent colectomy. We did multivariable logistic regression to investigate the influence of race, area socioeconomic status (SES), and other clinical and demographic characteristics on the number of LNs examined. RESULTS Between 1988 and 2004, white patients were more likely than black patients to have > or =12 LNs identified (odds ratio, 1.06; 95% confidence interval, 1.02-1.10) after adjustment for age, year of diagnosis, sex, marital status, tumor grade, stage, and subsite within the colon. After adjustment for SES, race was no longer significant (adjusted odds ratio, 1.00; 95% confidence interval, 0.96-1.04). There was, however, a significant positive trend between a patient's SES and having > or =12 LNs examined (P(trend) < 0.0001), with a 30% increased odds comparing the highest to the lowest quintiles of SES. We found that the association between SES and the dissection of > or =12 LNs was only present in individuals diagnosed after 1999. CONCLUSIONS The association between high SES and the examination of > or =12 LNs was only apparent from 2000 onward, and coincides with its dissemination and acceptance as a new standard of care. This suggests that the emergence of LN dissection as a quality indicator may have been more rapidly disseminated into higher SES groups.

Abstract
BACKGROUND Several studies have attributed racial disparities in cancer incidence and mortality to variances in socioeconomic status and health insurance coverage. However, an Institute of Medicine report found that blacks received lower quality care than whites after controlling for health insurance, income, and disease severity. METHODS To examine the effects of race on colorectal cancer outcomes within a single setting, the authors performed a retrospective cohort study that analyzed the cancer registry, billing, and medical records of 365 university hospital patients (175 blacks and 190 whites) diagnosed with stage II-IV colon cancer between 2000 and 2005. Racial differences in the quality (effectiveness and timeliness) of stage-specific colon cancer treatment (colectomy and chemotherapy) were examined after adjusting for socioeconomic status, health insurance coverage, sex, age, and marital status. RESULTS Blacks and whites had similar sociodemographic characteristics, tumor stage and site, quality of care, and health outcomes. Age and diagnostic stage were predictors of quality of care and mortality. Although few patients (5.8%) were uninsured, they were more likely to present at advanced stages (61.9% at stage IV) and die (76.2%) than privately insured and publicly insured patients (p = .002). CONCLUSIONS In a population without racial differences in socioeconomic status or insurance coverage, patients receive the same quality of care, regardless of racial distinction, and have similar health outcomes. Age, diagnostic stage, and health insurance coverage remained independently associated with mortality. Future studies of disparities in colon cancer treatment should examine sociocultural barriers to accessing appropriate care in various healthcare settings.

Abstract
PURPOSE The increase in mortality noted in African Americans with colon cancer is attributed to advanced stage at presentation and disparities in treatment received. The aim of this study was to assess the influence of race on the treatments and survival of colon cancer patients in an equal-access healthcare system. METHODS This retrospective cohort study included African American and white patients with colon cancer treated at Department of Defense facilities. Disease stage, surgery performed, chemotherapy used, and overall survival were evaluated. RESULTS Of the 6958 colon cancer patients identified, 1115 were African American. African Americans presented more frequently with stage IV disease, 23% vs 17% for whites (P < .001). There was no difference in surgical resection rates for African American or whites (85.8% vs 85.5%, respectively; chi2, P > .05). There was no difference in the use of systemic chemotherapy for stage III colon cancer (73.5% for African Americans vs 72.2% for whites; chi2, P > .05) or stage IV colon cancer (56.3% for African Americans vs 54.4% for whites; chi2, P > .05). The overall 5-year survival rate was similar for African American and white patients (56.1% vs 58.5%, respectively; log-rank, P > .05). After adjusting for gender, age, tumor grade, and stage, African American race was not a risk factor for survival in Cox proportional hazard analysis (hazard ratio, 0.981; 95% confidence interval, 0.888-1.084). CONCLUSIONS In an equal-access healthcare system, African American race is not associated with an increase in mortality. African American patients undergo surgery and chemotherapy is administered at rates equal to whites for all stages of colon cancer.

Abstract
PURPOSE Racial disparities in colorectal cancer (CRC) survival are documented, but there are few data on comparative response to chemotherapy. A subgroup analysis of a multisite National Cancer Institute-sponsored trial (N9741) was performed comparing outcomes of black and white patients with metastatic CRC receiving uniform treatment. PATIENTS AND METHODS Adverse events (AEs), response rate (RR), time to progression (TTP), overall survival (OS), and dose-intensity were examined as a function of self-reported race in 1,412 patients treated with irinotecan/fluorouracil, fluorouracil/oxaliplatin, or irinotecan/oxaliplatin. Pharmacogenetic analysis was performed on 486 patients with blood available for germline DNA analysis. RESULTS OS was 1.5 months shorter and TTP was 0.6 months shorter in black than white patients (OS: hazard ratio [HR] = 1.13; 95% CI, 0.90 to 1.42; TTP: HR = 0.91, 95% CI, 0.73 to 1.13); neither difference was statistically significant. RR was significantly higher in whites (41%) than blacks (28%; P = .008). Grade 3 or greater AEs were also higher in whites (48%) than blacks (34%; P = .004). These relationships were maintained in multivariate models adjusting for arm, age, sex, and performance status. There was no difference in dose-intensity of delivered therapy. Significant racial differences in prevalence of pharmacogenetic variants were observed, although small sample size precluded investigating the relationship between treatment, race, and genotype. CONCLUSION OS and TTP are similar in black and white patients treated per protocol with standardized therapy for metastatic CRC. However, RR and AEs vary considerably by race. The marked racial differences in relevant pharmacogenetics, a potential explanation for differing RR and AEs, are worthy of future study.

Abstract
BACKGROUND Racial disparities in cancer outcomes have been observed in several malignancies. However, it is unclear if survival differences persist after adjusting for clinical, demographic, and treatment variables. Our objective was to determine whether racial disparities in survival exist among patients enrolled in consecutive trials conducted by the Southwest Oncology Group (SWOG). METHODS We identified 19 457 adult cancer patients (6676 with breast, 2699 with lung, 1244 with colon, 1429 with ovarian, and 1843 with prostate cancers; 1291 with lymphoma; 2067 with leukemia; and 2208 with multiple myeloma) who were treated on 35 SWOG randomized phase III clinical trials from October 1, 1974, through November 29, 2001. Patients were grouped according to studies of diseases with similar histology and stage. Cox regression was used to evaluate the association between race and overall survival within each disease site grouping, controlling for available prognostic factors plus education and income, which are surrogates for socioeconomic status. Median and ten-year overall survival estimates were derived by the Kaplan-Meier method. All statistical tests were two-sided. RESULTS Of 19 457 patients registered, 2308 (11.9%, range = 3.9%-21.6%) were African American. After adjustment for prognostic factors, African American race was associated with increased mortality in patients with early-stage premenopausal breast cancer (hazard ratio [HR] for death = 1.41, 95% confidence interval [CI] = 1.10 to 1.82; P = .007), early-stage postmenopausal breast cancer (HR for death = 1.49, 95% CI = 1.28 to 1.73; P < .001), advanced-stage ovarian cancer (HR for death = 1.61, 95% CI = 1.18 to 2.18; P = .002), and advanced-stage prostate cancer (HR for death = 1.21, 95% CI = 1.08 to 1.37; P = .001). No statistically significant association between race and survival for lung cancer, colon cancer, lymphoma, leukemia, or myeloma was observed. Additional adjustments for socioeconomic status did not substantially change these observations. Ten-year (and median) overall survival rates for African American vs all other patients were 68% (not reached) vs 77% (not reached), respectively, for early-stage, premenopausal breast cancer; 52% (10.2 years) vs 62% (13.5 years) for early-stage, postmenopausal breast cancer; 13% (1.3 years) vs 17% (2.3 years) for advanced ovarian cancer; and 6% (2.2 years) vs 9% (2.7 years) for advanced prostate cancer. CONCLUSIONS African American patients with sex-specific cancers had worse survival than white patients, despite enrollment on phase III SWOG trials with uniform stage, treatment, and follow-up.

Abstract
Many cancer treatment and prevention trials as well as surveillance programs suffer from a disproportionately low rate of accrual and a high rate of noncompliance or dropouts of racial minorities and the poor. One suggested strategy to help remediate this trend is to directly involve those targeted populations within the development, implementation, and evaluation of these services. The Radiation Oncology Community Outreach Group (ROCOG) and Neighborhood Cancer Care Cooperative (NCCC) are designed based upon this type of highly collaborative organizational structure, consistent with the general principles of community-based participatory research. Funded by the National Cancer Institute Cancer Disparities Research Partnership program, ROCOG/NCCC provide oncology-focused, community hospital-based initiatives intended to help close the cancer disparities gap. This article presents a descriptive case study of the organizational and political process that preceded our grant proposal submission, the potential benefits and difficulties associated with our extensive collaborative model, and an example of how highly competitive health care organizations can become partners in narrowly focused initiatives aimed at a greater social good.

Abstract
African Americans are disproportionately burdened with colorectal cancer. Although incidence and mortality rates have declined in the past two decades, the disparity in health outcomes has progressively increased. This comprehensive review examines the existing literature regarding racial disparities in colorectal cancer screening, stage at diagnosis, and treatment to determine if differences exist in the quality of care delivered to African Americans. A comprehensive review of relevant literature was performed. Two databases (EBSCOHOST Academic Search Premier and Scopus) were searched from 2000 to 2007. Articles that assessed racial disparities in colorectal cancer screening, stage of disease at diagnosis, and treatment were selected. The majority of studies identified examined colorectal cancer screening outcomes. Although racial disparities in screening have diminished in recent years, African American men and women continue to have higher colorectal cancer incidence and mortality rates and are diagnosed at more advanced stages. Several studies regarding stage of disease at diagnosis identified socioeconomic status (SES) and health insurance status as major determinants of disparity. However, some studies found significant racial disparities even after controlling for these factors. Racial disparities in treatment were also found at various diagnostic stages. Many factors affecting disparities between African Americans and Whites in colorectal cancer incidence and mortality remain unexplained. Although the importance of tumor biology, genetics, and lifestyle risk factors have been established, prime sociodemographic factors need further examination to understand variances in the care of African Americans diagnosed with colorectal cancer.

Abstract
There is strong evidence that colorectal cancer survival differs between socioeconomic groups. We analysed data on 2481 patients diagnosed during 1989-1997 and recruited to a randomised controlled clinical trial (AXIS, ISRCTN32414363) of chemotherapy and radiotherapy for colorectal cancer. Crude and relative survival at 1 and 5 years was estimated in five categories of socioeconomic deprivation. Multiple imputation was used to account for missing data on tumour stage. A multivariable fractional polynomial model was fitted to estimate the excess hazard of death in each deprivation category, adjusting for the confounding effects of age, stage, cancer site (colon, rectum) and sex, using generalised linear models. Relative survival in the trial patients was higher than in the general population of England and Wales. The socioeconomic gradient in survival was much smaller than that seen for colorectal cancer patients in the general population, both at 1 year -3.2% (95% CI -7.3 to 1.0%, P=0.14) and at 5 years -1.7% (95% CI -8.3 to 4.9%, P=0.61). Given equal treatment, colorectal cancer survival in England and Wales does not appear to depend on socioeconomic status, suggesting that the socioeconomic gradient in survival in the general population could well be due to health-care system factors.
