Abstract
Pancreatic cancer (PCa) remains a formidable global health challenge, with high mortality rates and limited treatment options. While advancements in pharmacology have led to improved outcomes for various cancers, PCa continues to exhibit significant health disparities, disproportionately affecting certain populations. This paper explores the intersection of pharmacology and anthropology in understanding the health disparities associated with PCa. By considering the socio-cultural, economic, and behavioral factors that influence the development, diagnosis, treatment, and outcomes of PCa, pharmacologic anthropology provides a comprehensive framework to address these disparities and improve patient care.

Abstract
There are disparities in outcomes for patients with multiple myeloma (MM). We evaluated the influence of sociodemographic factors on global disparities in outcomes for patients with MM. This rapid evidence assessment (PROSPERO, CRD42021248461) followed PRISMA-P guidelines and used the PICOS framework. PubMed and Embase® were searched for articles in English from 2011 to 2021. The title, abstract, and full text of articles were screened according to inclusion/exclusion criteria. The sociodemographic factors assessed were age, sex, race/ethnicity, socioeconomic status, and geographic location. Outcomes were diagnosis, access to treatment, and patient outcomes. Of 84 articles included, 48 were US-based. Worldwide, increasing age and low socioeconomic status were associated with worse patient outcomes. In the US, men typically had worse outcomes than women, although women had poorer access to treatment, as did Black, Asian, and Hispanic patients. No consistent disparities due to sex were seen outside the US, and for most factors and outcomes, no consistent disparities could be identified globally. Too few studies examined disparities in diagnosis to draw firm conclusions. This first systematic analysis of health disparities in patients with MM identified specific populations affected, highlighting a need for additional research focused on assessing patterns, trends, and underlying drivers of disparities in MM.

Cancer Control 2023; 30:10732748231204474. [PMID: 37771179 PMCID: PMC10542233 DOI: 10.1177/10732748231204474] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2023] [Revised: 07/21/2023] [Accepted: 09/12/2023] [Indexed: 09/30/2023] Open
Abstract
PURPOSE The purpose of this study was to assess the association of comorbidity burden with overall survival, accounting for racial/ethnic and socioeconomic differences in patients with cancer. METHODS In this retrospective cohort study, patients newly diagnosed with cancer between 2010 and 2018 were identified from a large health plan in southern California. Cancer registry data were linked with electronic health records (EHR). Comorbidity burden was defined by the Elixhauser comorbidity index (ECI). Patients were followed through December 2019 to assess all-cause mortality. Association of comorbidity burden with all-cause mortality was evaluated using Cox proportional hazards model. Crude and adjusted hazard ratio (HR, 95%CI) were determined. RESULTS Of 153,270 patients included in the analysis, 29% died during the ensuing 10-year follow-up. Nearly 49% were patients of color, and 32% had an ECI > 4. After adjusting for age, sex, race/ethnicity, cancer stage, smoking status, insurance payor, medical center, year of cancer diagnosis, and cancer treatments, we observed a trend demonstrating higher mortality risk by decreasing socioeconomic status (SES) (P-trend<.05). Compared to patients in the highest SES quintile, patients in the lowest, second lowest, middle, and second highest quintiles had 25%, 21%, 18%, and 11% higher risk of mortality, respectively [(HR, 95%CI): 1.25 (1.21-1.29), 1.21 (1.18-1.25), 1.18 (1.15-1.22), and 1.11 (1.07-1.14), respectively]. When we additionally adjusted for ECI, the adjusted HRs for SES were slightly attenuated; however, the trend persisted. Patients with higher comorbidity burden had higher mortality risk compared to patients with ECI score = 0 in the adjusted model [(HR, 95%CI): 1.22 (1.17-1.28), 1.48 (1.42-1.55), 1.80 (1.72-1.89), 2.24 (2.14-2.34), and 3.39 (3.25-3.53) for ECI = 1, 2, 3, 4, and >5, respectively]. CONCLUSIONS Comorbidity burden affects overall survival in cancer patients irrespective of racial/ethnic and SES differences. Reducing comorbidity burden can reduce some, but not all, of the mortality risk associated with lower SES.

CANCER COMMUNICATIONS (LONDON, ENGLAND) 2022; 43:87-99. [PMID: 36353792 PMCID: PMC9859729 DOI: 10.1002/cac2.12375] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Revised: 08/01/2022] [Accepted: 10/11/2022] [Indexed: 11/11/2022]
Abstract
BACKGROUND Survival from pancreatic cancer is low worldwide. In the US, the 5-year relative survival has been slightly higher for women, whites and younger patients than for their counterparts, and differences in age and stage at diagnosis [Corrections added Nov 16, 2022, after first online publication: a new affiliation is added to Maja Nikšić] may contribute to this pattern. We aimed to examine trends in survival by race, stage, age and sex for adults (15-99 years) diagnosed with pancreatic cancer in the US. METHODS This population-based study included 399,427 adults registered with pancreatic cancer in 41 US state cancer registries during 2001-2014, with follow-up to December 31, 2014. We estimated age-specific and age-standardized net survival at 1 and 5 years. RESULTS Overall, 12.3% of patients were blacks, and 84.2% were whites. About 9.5% of patients were diagnosed with localized disease, but 50.5% were diagnosed at an advanced stage; slightly more among blacks, mainly among men. No substantial changes were seen over time (2001-2003, 2004-2008, 2009-2014). In general, 1-year net survival was higher in whites than in blacks (26.1% vs. 22.1% during 2001-2003, 35.1% vs. 31.4% during 2009-2014). This difference was particularly evident among patients with localized disease (49.6% in whites vs. 44.6% in blacks during 2001-2003, 60.1% vs. 55.3% during 2009-2014). The survival gap between blacks and whites with localized disease was persistent at 5 years after diagnosis, and it widened over time (from 24.0% vs. 21.3% during 2001-2003 to 39.7% vs. 31.0% during 2009-2014). The survival gap was wider among men than among women. CONCLUSIONS Gaps in 1- and 5-year survival between blacks and whites were persistent throughout 2001-2014, especially for patients diagnosed with a localized tumor, for which surgery is currently the only treatment modality with the potential for cure.

Abstract
Background Survival rates are usually used to evaluate the effect of cancer treatment and prevention. This study aims to analyze the 5-year relative survival of non-Hodgkin lymphoma (NHL) in United States using population-based cancer registry data. Methods A period analysis was used to evaluate the improvement in long-term prognosis of patients with NHL from 2004 to 2018, and a generalized linear model was developed to predict the 5-year relative survival rates of patients during 2019–2023 based on data from the SEER database stratified by age, sex, race and subtype. Results In this study, relative survival improved for all NHL, although the extent of improvement varied by sex, age group and lymphoma subtype. Survival improvement was also noted for NHL subtypes, although the extent varied, with marginal-zone lymphoma having the highest 5-year relative survival rate (92.5%) followed by follicular lymphoma (91.6%) and chronic lymphocytic leukemia/small lymphocytic lymphoma (87.3%). Across all subtypes, survival rates were slightly higher in females than in males. Survival rates are lower in the elderly than in the young. Furthermore, the study demonstrated that black patients had lower NHL survival rates than white patients. Survival rates for NHL were higher in rural areas than in urban areas. Patients with extra-nodal NHL had a higher survival rate than patients with nodal NHL. Conclusion Overall, patient survival rates for NHL gradually improved during 2004–2018. The trend continues with a survival rate of 75.2% for the period 2019–2023. Analysis by NHL subtype and subgroups indicating that etiology and risk factors may differ by subtype. Identification of population-specific prevention strategies and treatments for each subtype can be aided by understanding these variations.

Abstract
Low-dose computed tomography (LDCT), an accepted U.S. screening tool for early lung cancer detection, is not widely-used in Puerto Rico. We investigated knowledge and attitudes about LDCT in focus groups of primary care physicians (PCP) and individuals at high risk for lung cancer (HRI) in Puerto Rico. Transcribed/translated audio-recorded discussions were analyzed with the constant comparison method. Both groups had limited knowledge about LDCT and concerns regarding insurance coverage. Most HRIs had never had a provider recommend LDCT and believed that having symptoms was necessary to obtain LDCT screening. Perceived barriers included fears about results and the procedure; a perceived benefit was having early detection and possibly being cured. Few PCPs had ever recommended LDCT to a patient, with those who had basing their decision on symptoms/smoking history but having challenges with insurance. More education on LDCT is needed among HRIs, and U.S. Preventive Services Task Force guidelines should be widely distributed to encourage physician recommendations.

Abstract
Background Disparities driven by socioeconomic factors have been shown to impact outcomes for cancer patients. We sought to explore this relationship among patients with multiple myeloma (MM) who were not considered for hematopoietic stem cell transplant in the first-line setting and how it varied over time. Methods We queried the National Cancer Database for patients diagnosed with MM between 2004 and 2016 and included only those who received systemic therapy as the first-line treatment. Enrollment rates for therapy were calculated as receipt of systemic therapy as the incident event of interest (numerator) over time to initiation of therapy (denominator) and used to calculate incident rate ratios that were further analyzed using Poisson regression analysis. A multivariate Cox proportional hazards model was constructed for survival analysis, and differences were reported as hazard ratios (HRs). Results We identified 56,102 patients for enrollment analysis and 50,543 patients for survival analysis. Therapy enrollment in a multivariate model was significantly impacted by race and sex (p < .005). Advanced age, earlier year of diagnosis, lack of insurance or Medicaid, and higher comorbidity were associated with poor survival (HR > 1), whereas female sex, non-Hispanic black race, higher income, and treatment at an academic center were associated with improved survival (HR < 1). Conclusion Disparities in treatment of MM exist and are caused by a complex interplay of multiple factors, with socioeconomic factor playing a significant role. Studies exploring such determinants may help in equitable distribution of resources to overcome such differences.

Abstract
BACKGROUND Several new treatments that improve survival in clinical trials have been developed for various solid malignancies in advanced stages. The effect of these options on survival in the general population is currently unknown. METHODS Cancers for which 2 or more new treatment options have been approved by the US Food and Drug Administration during the years 2009 through 2011 for the treatment of advanced disease were identified, including adenocarcinoma of the lung, melanoma, breast cancer, prostate cancer, and renal cell carcinoma. Kaplan-Meier analysis was used to compare overall survival for these conditions in the Surveillance, Epidemiology, and End Results database for the periods 2007 to 2008, 2009 to 2010, and 2011 to 2012. Hazard ratios derived from adjusted, shared frailty models for cancer-specific survival were calculated as well for the years of diagnosis (2007-2008, 2009-2010, and 2011-2012). RESULTS Two-year survival increased for patients with advanced-stage lung adenocarcinoma (+3.0 percentage points), melanoma (+3.4 percentage points), and breast cancer (+2.7 percentage points). When only patients aged 15 to 64 years were included, 2-year survival for those with melanoma increased by +6.7 percentage points. No change in survival was observed for renal cell carcinoma. Decreases in the hazard ratio for cancer-specific mortality were observed during the period 2011 to 2012 compared with 2007 to 2008 for lung adenocarcinoma, melanoma, and breast cancer. CONCLUSIONS Small increases in 2-year survival were observed between the periods 2007 to 2008 and 2011 to 2012 for lung adenocarcinoma, melanoma, and prostate cancer. Cancer-specific mortality decreased for each of these cancers among patients who were diagnosed between the periods 2007 to 2008 and 2011 to 2013. These findings suggest that newer treatment options are beginning to increase survival for stage IV cancers at the population level.

Abstract
OBJECTIVES African Americans (AAs) have disproportionately higher incidence and lower survival rates from pancreatic cancer compared with whites. Historically, this disparity has been attributed to modifiable risk factors. Recent studies suggest that nonmodifiable aspects may also play an important role. We review these new contributions as potential targets for closing the disparity. METHODS A PubMed search was conducted to review studies of nonmodifiable elements contributing to pancreatic cancer disparities in AAs. RESULTS Several nonmodifiable risks are associated with the racial disparity in pancreatic cancer. SSTR5 P335L, Kaiso, and KDM4/JMJD2A demonstrate differential racial expression, increasing their potential as therapeutic targets. Many social determinants of health and their associations with diabetes, obesity, and the microbiome are partially modifiable risk factors that significantly contribute to outcomes in minorities. Barriers to progress include the low minority inclusion in research studies. CONCLUSIONS Genomics, epigenetics, the microbiome, and social determinants of health are components that contribute to the pancreatic cancer disparity in AAs. These factors can be researched, targeted, and modified to improve mortality rates. Closing the disparity in pancreatic cancer will require an integrated approach of personalized medicine, increased minority recruitment to studies, and advanced health care/education access.

Abstract
BACKGROUND The lifetime risk of developing leukemia in the United States is 1.5%. There are challenges in the estimation of population-based survival using registry data because treatments and prognosis vary greatly by subtype. The objective of the current study was to determine leukemia survival estimates in the United States from 1995 to 2009 according to subtype, sex, geographical area, and race. METHODS Five-year net survival was estimated using data for 370,994 patients from 43 registries in 37 states and in 6 metropolitan areas, covering approximately 81% of the adult (15-99 years) US population. Leukemia was categorized according to principal subtype (chronic lymphocytic leukemia, acute myeloid leukemia, and acute lymphocytic leukemia), and subcategorized in accordance with the HAEMACARE protocol. We analyzed age-standardized 5-year net survival by calendar period (1995-1999, 2000-2004, and 2005-2009), leukemia subtype, sex, race, and US state. RESULTS The age-standardized 5-year net survival estimates increased from 45.0% for patients diagnosed during 1995-1999 to 49.0% for those diagnosed during 2000-2004 and 52.0% for those diagnosed during 2005-2009. For patients diagnosed during 2005-2009, 5-year survival was 18.2% (95% confidence interval [95% CI], 17.8%-18.6%) for acute myeloid leukemia, 44.0% (95% CI, 43.2%-44.8%) for acute lymphocytic leukemia, and 77.3% (95% CI, 76.9%-77.7%) for chronic lymphocytic leukemia. For nearly all leukemia subtypes, survival declined in successive age groups above 45 to 54 years. Men were found to have slightly lower survival than women; however, this discrepancy was noted to have fallen in successive calendar periods. Net survival was substantially higher in white than black patients in all calendar periods. There were large differences in survival noted between states and metropolitan areas. CONCLUSIONS Survival from leukemia in US adults improved during 1995-2009. Some geographical differences in survival may be related to access to care. We found disparities in survival by sex and between black and white patients.

Stratified survival of resected and overall pancreatic cancer patients in Europe and the USA in the early twenty-first century: a large, international population-based study. BMC Med 2018; 16:125. [PMID: 30126408 PMCID: PMC6102804 DOI: 10.1186/s12916-018-1120-9] [Citation(s) in RCA: 81] [Impact Index Per Article: 13.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/21/2018] [Accepted: 07/09/2018] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND The prognosis of pancreatic cancer (PaC) strongly varies across different stages and age groups, which has unfortunately not been well recorded in the literature. This international population-based study aimed to provide tumor-node-metastasis (TNM) stage- and age-specific survival estimates and trends in resected and overall (resected and unresected) PaC in the early twenty-first century. METHODS Using data from the US Surveillance, Epidemiology, and End Results-18 Program and the national cancer registries of the Netherlands, Belgium, Norway, and Slovenia, short-term and long-term overall survival results stratified by TNM stage and age in resected and overall primary PaC, irrespective of being microscopically confirmed or not, in 2003-2014 were computed using the Kaplan-Meier method. The temporal survival trends over three predefined periods (2003-2005, 2006-2008, and 2009-2011) were further examined using the log-rank test. RESULTS In total, data for 125,183 patients were analyzed. Overall, age-stratified 3-year survival was 20-34% (< 60 years), 14-25% (60-69 years), and 9-13% (≥ 70 years) in stages I-II PaC; and 2-5% (< 60 years), 1-2% (60-69 years), and < 1-1% (≥ 70 years) in stages III-IV cancer. Patients who underwent operation had higher 3-year survival in each stage and age group (stages I-II: 23-39% (< 60 years), 16-31% (60-69 years), and 17-30% (≥ 70 years); stages III-IV: 5-19% (< 70 years) and 2-14% (≥ 70 years)). Perioperative survival also decreased with advancing stage and older age (stages I-II: 98-100% (< 60 years), 97-99% (60-69 years), and 94-99% (≥ 70 years); stages III-IV: 94-99% (< 70 years) and 81-96% (≥ 70 years)). Between 2003 and 2005 and 2009-2011, for overall PaC, both short-term and long-term survival improvements were observed in all countries except Belgium; for resected disease, short-term improvements were present only in the USA and Slovenia, but long-term improvements were observed in all countries except Slovenia, with stage-specific variations. CONCLUSIONS Our large international study provides TNM stage- and age-specific population-based survival in overall and resected PaC that will facilitate clinical counseling. While the survival expectations for patients with resected PaC are substantially higher than the widely available and known dismal survival predictions for overall patients, conclusions on the benefits of resection cannot be made from this observational study. Patients with advanced-stage disease and/or older age should undergo careful risk assessment before treatment. Limited but inspiring improvement in survival is observed.

[PMID: 30043318 DOI: 10.1245/s10434-018-6680-6] [Citation(s) in RCA: 58] [Impact Index Per Article: 9.7] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2018] [Indexed: 01/05/2023]
Abstract
AIM To identify factors associated with refusal of surgery in patients with early-stage pancreatic cancer and estimate the impact of this decision on survival. METHODS Using the National Cancer Data Base, 26,358 patients were identified with potentially resectable tumors (pretreatment clinical stage I: T1 or T2 N0M0). Multivariate models were employed to identify factors predicting failure to undergo surgery and assess the impact on survival. RESULTS Of early-stage patients who were recommended surgery, 7.8% (N = 992) refused surgery for resectable early-stage pancreatic cancer. On multivariable analysis, patients were more likely to refuse surgery if they were older [odds ratio (OR) = 1.18; 95% confidence interval (CI) 1.16-1.19], female (OR = 1.52; 95% CI 1.33-1.73), African American (vs White, OR = 1.79; 95% CI 1.37-2.34), on Medicare/Medicaid (vs private, OR = 2.75; 95% CI 1.54-4.92) or had higher Charlson-Deyo score (2 vs 0, OR = 1.33; 95% CI 1.03-1.72). Patients were also significantly more likely to refuse surgery if they were seen at a center that is not an academic/research program (OR 1.9; 95% CI 1.6-2.27). Patients who were recommended surgery but refused had significantly worse survival than those with stage I who received surgery [median survival 6.8 vs 24 months, Cox hazard ratio (HR) 3.41; 95% CI 3.12-3.60]. CONCLUSIONS The percentage of patients refusing surgery for operable early-stage pancreatic cancer has been decreasing in the last decade but remains a significant issue that affects survival. Disparities in refusal of surgery are independently associated with several variables including gender, race, and insurance. To mitigate national disparities in surgical care, future studies should focus on exploring potential reasons for refusal and developing communication interventions.

The LEAD study protocol: a mixed-method cohort study evaluating the lung cancer diagnostic and pre-treatment pathways of patients from Culturally and Linguistically Diverse (CALD) backgrounds compared to patients from Anglo-Australian backgrounds. BMC Cancer 2018; 18:754. [PMID: 30031382 PMCID: PMC6054738 DOI: 10.1186/s12885-018-4671-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2018] [Accepted: 07/16/2018] [Indexed: 12/13/2022] Open
Abstract
Background Lung cancer is the leading cause of cancer mortality worldwide. Early diagnosis and treatment is a key factor in reducing mortality and improving patient outcomes. To achieve this, it is important to understand the diagnostic pathways of cancer patients. Patients from Culturally and Linguistically Diverse (CALD) are a vulnerable group for lung cancer with higher mortality rates than Caucasian patients. The aim of this study is to explore differences in the lung cancer diagnostic pathways between CALD and Anglo-Australian patients and factors underlying these differences. Methods This is a prospective, observational cohort study using a mixed-method approach. Quantitative data regarding time intervals in the lung cancer diagnostic pathways will be gathered via patient surveys, General practitioner (GP) review of general practice records, and case-note analysis of hospital records. Qualitative data will be gathered via structured interviews with lung cancer patients, GPs, and hospital specialists. The study will be conducted in five study sites across three states in Australia. Anglo-Australian patients and patients from five CALD groups (i.e., Arabic, Chinese, Greek, Italian and Vietnamese communities) will mainly be identified through the list of new cases presented at lung multidisciplinary team meetings. For the quantitative component, it is anticipated that 724 patients (362 Anglo-Australian and 362 CALD patients) will be recruited to obtain a final sample of 290 (145 per group) assuming a 50% patient survey completion rate and a 80% GP record review completion rate. For the qualitative component, 60 interviews with lung cancer patients (10 Anglo-Australian and 10 patients per CALD group), 20 interviews with GPs, and 20 interviews with specialists will be conducted. Discussion This is the first Australian study to compare the time intervals along the lung cancer diagnostic pathway between CALD and Anglo-Australian patients. The study will also explore the underlying patient, healthcare provider, and health system factors that influence the time intervals in the two groups. This information will improve our understanding of the effect of ethnicity on health outcomes among lung cancer patients and will inform future interventions aimed at early diagnosis and treatment for lung cancer, particularly patients from CALD backgrounds. Trial registration The project was retrospectively registered with Australian New Zealand Clinical Trials Registry (registration number: ACTRN12617000957392, date registered: 4th July 2017).

Abstract
African Americans (AA) have the highest incidence and mortality rates with lung cancer. They are diagnosed at an earlier age with more advanced disease. Programmed cell death protein-1 inhibitor, Nivolumab, was approved as a second-line agent after failure of platinum-based therapy for advanced or metastatic non-small cell lung cancer (NSCLC). The original studies leading to the approval of Nivolumab had insufficient AA patients, thus there is still inadequate knowledge on treatment outcomes among AA patients. Our primary study endpoints were to determine the median overall survival, 1-year overall survival rate, median progression-free survival, and 1-year progression-free survival rate of patients with advanced or metastatic non-small cell lung cancer on Nivolumab. Our secondary study endpoints were to determine the overall tumor response rate, median time to response, median duration of response, and incidence of treatment-related adverse events of grade 3 or 4. In this retrospective study, we reviewed the charts of 38 patients, 29 of which were AA, with advanced or metastatic NSCLC who received Nivolumab from March 1, 2015 until November 30, 2017 from a single community-based cancer center and compared our results with historical data. Adenocarcinoma was the most common histology (71%) among all patients. Seven (18%) continued to use Nivolumab while 21 (55%) discontinued the treatment mainly due to progression of the disease. The median overall survival was 21.4 months (95% CI 13.5-27.4) and 17.6 months (95% CI 11.5-27.6) for all the patients and AA, respectively. Both have statistically significant difference (P < 0.001) compared to the historical studies of Borghaei et al. and Brahmer et al. At 1 year, the overall survival rate was 73% (95% CI 50-86) and 66% (95% CI 40-82) for all patients and AA, respectively. The median progression-free survival was also statistically significant (P < 0.001) between all the patients 6.3 months (95% CI 2.8-8), AA 6.0 months (95% CI 2.3-8.0), and the said historical studies. The 1-year progression-free survival rate was 23% (95% CI 10-39) and 28% (95% CI 12-47) for all patients and AA, respectively. Overall tumor response rate which includes complete and partial responses was 21% (95% CI 10-37) and 24% (95% CI 10-43) for all patients and AA, respectively. The median time to response was 3 and 2.8 months for all patients and AA, respectively. The median duration of response was 3.8 and 4.0 months for all patients and AA, respectively. Treatment-related adverse events of grade 3 or 4 were reported in 8 and 10% in all patients and AA, respectively, similar to the rates previously shown. AA patients with advanced or metastatic NSCLC on Nivolumab had increased overall survival and progression-free survival with similar grade 3 or 4 treatment-related adverse events. Providing adequate access to immunotherapy is indispensable to maximize survival benefit for AA patients.

Abstract
INTRODUCTION Despite increasingly mixed communities in large cities, there remains a paucity of absolute and comparative data concerning the treatment, access and survival of British Asians with pancreatic cancer. METHODS A prospective database of 1038 patients with a diagnosis of pancreatic cancer from 2003 to 2012 was analysed. Asian/Asian British was defined as patients identifying themselves as originating from India, Bangladesh or Pakistan. RESULTS No significant difference was observed in gender split for both Asian/Asian British and White British (AAB and WB). The incidence of pancreas cancer was also equivalent between the two groups at 8.1 versus 8.8 per 100,000 of the population. Age at presentation was significantly younger in AABs when compared to WBs (67 vs. 70 years, p = 0.003). Whilst median maximal tumour diameter, node status and the incidence of metastases were not different between AABs and WBs, the AABs had a significantly greater median T-stage (3.0 versus 2.5, p = 0.0024). The percentage of patients referred for chemotherapy was significantly higher in the AAB group (70.5 vs. 47.7 %, p = 0.0015). Overall survival and survival for patients having palliative treatment were significantly greater in AABs (4.6 vs. 6.1 months and 3.7 vs. 5.1 months). CONCLUSION This study demonstrates that AAB patients are present with pancreatic cancer at a younger age and that when receiving palliative chemotherapy their survival is significantly better. Further studies and larger data sets over a longer period are required. It is important to examine further the complexity of incidence and survival in ethnic minorities and investigate the underlying reasons when differences are demonstrated.

Abstract
Outcomes have improved considerably in multiple myeloma (MM), but disparities among racial-ethnic groups exist. Differences in utilization of novel therapeutics are likely contributing factors. We explored such differences from the SEER-Medicare database. A utilization analysis of lenalidomide, thalidomide, bortezomib, and stem cell transplant (SCT) was performed for patients diagnosed with MM between 2007 and 2009, including use over time, use by race, time-dependent trends for each racial subgroup, and survival analysis. A total of 5338 MM patients were included with median 2.4-year follow-up. Within the first year of MM diagnosis, utilization of lenalidomide, bortezomib, SCT, and more than one novel agent increased over time while utilization of thalidomide decreased. There was significantly lower utilization of lenalidomide among African-Americans (P < 0.01), higher thalidomide use among Hispanics and Asians (P < 0.01), and lower bortezomib use among Asians (P < 0.01). Hispanics had the highest median number of days to first dose of bortezomib (P = 0.02) and the lowest utilization of SCT (P < 0.01). Hispanics and Asians were the only groups without notable increases in lenalidomide and bortezomib use, respectively. SCT utilization increased over time for all except African-Americans. SCT use within the first year after diagnosis was associated with better overall survival (HR 0.52; 95% CI: 0.4-0.68), while bortezomib use was associated with inferior survival (HR 1.14; 95% CI 1.02-1.28). We noted considerable variability in MM therapeutics utilization with seeming inequity for racial-ethnic minorities. These trends should be considered to eliminate drug access and utilization disparities and achieve equitable benefit of therapeutic advances across all races.

Abstract
OBJECTIVE Prostate cancer mortality rates have decreased over recent decades, but racial disparities in prostate cancer survival still present as a serious challenge. These disparities may be impacted by age; in fact, African-American men younger than age 65 have prostate cancer mortality rates nearly three times greater than that of White men. Therefore, a systematic literature review was conducted in Medline and EMBASE databases focusing on articles comparing survival and mortality rates for prostate cancer patients across age and race. DESIGN Articles included were based on the following criteria: (1) included African-American and White prostate cancer patients residing in the US; (2) measured racial disparities across distinct age categories with at least one category below and one above age 65; and (3) addressed racial disparities in terms of overall survival or mortality. RESULTS Twenty eight articles compared survival and mortality disparities between African-American and White prostate cancer patients across different age categories. Of the 28 articles, 19 articles (68%) showed disparities decreased with age, 8 articles (29%) showed disparities constant with age, and 1 article (3%) showed disparities increased with age. CONCLUSIONS More often the survival and mortality gap between African-American and White prostate cancer patients decreases with age. Additional studies are needed to elucidate other factors that may influence racial disparities in prostate cancer patients. These results provide insight into the racial disparities in prostate cancer and suggest more resources should be directed towards decreasing the disparity gap in younger prostate cancer patients.

Abstract
BACKGROUND Both minority race and lack of health insurance are risk factors for lower survival in colorectal cancer (CRC) but the interaction between the two factors has not been explored in detail. METHODS One to 5-year survival by race/ethnic group and insurance type for patients with CRC diagnosed in 2007-13 and registered in the Surveillance Epidemiology, and End RESULTS: database were explored. Shared frailty models were computed to further explore the association between CRC specific survival and insurance status after adjustment for demographic and treatment variables. RESULTS Age-adjusted 5-year survival estimates were 70.4% for non-Hispanic whites (nHW), 62.7% for non-Hispanic blacks (nHB), 70.2% for Hispanics, 64.7% for Native Americans, and 73.1% for Asian/Pacific Islanders (API). Survival was greater for patients with insurance other than Medicaid for all races, but the differential in survival varied with race, with the greatest difference being seen for nHW at +25.0% and +20.2%, respectively, for Medicaid and uninsured versus other insurance. Similar results were observed for stage- and age-specific analyses, with survival being consistently higher for nHW and API compared to other groups. After confounder adjustment, hazard ratios of 1.53 and 1.50 for CRC-specific survival were observed for Medicaid and uninsured. Racial/ethnic differences remained significant only for nHB compared to nHW. CONCLUSIONS Race/ethnic group and insurance type are partially independent factors affecting survival expectations for patients diagnosed with CRC. NHB had lower than expected survival for all insurance types.

Abstract
PURPOSE Lymphoid malignancies are among the most common cancers diagnosed in adolescents and young adults (AYAs). However, little is known about the factors affecting survival in AYAs with non-Hodgkin lymphoma (NHL). We evaluated if survival differs by race/ethnicity and neighborhood socioeconomic status in AYAs with NHL. METHODS AYAs aged 15-39 diagnosed with incident NHL during 1990-2010 at Kaiser Permanente Southern California (KPSC), a large managed care organization, were identified. Demographic information and cancer characteristics were obtained from KPSC's cancer registry. Mortality data were obtained from California and national death files. Patients were followed from NHL diagnosis to 5 years postdiagnosis or 12/31/2012, whichever came first. Multivariable Cox model was used to evaluate the association between race/ethnicity, neighborhood income/education level, and mortality, adjusting for age, gender, stage, year of diagnosis, and histology subtype. RESULTS A total of 718 AYAs with NHL were included (mean age at diagnosis: 31 years); 45% were non-Hispanic white, 10% were African American, 36% were Hispanic, and 8% were Asian/Pacific Islander. Overall 5-year mortality was 30%. Compared to non-Hispanic whites, Asians/Pacific Islanders had increased 5-year mortality (hazard ratio=1.95, 95% confidence interval: 0.93-4.07). No significant increase in mortality was found for Hispanics or African Americans. Lower neighborhood income but not education level was associated with worse overall survival. CONCLUSION A survival disparity for Asians/Pacific Islanders and low-income neighborhoods was observed in AYAs with NHL despite relatively equal access to care. These results call for studies to further understand mechanisms underlying the inferior outcomes among disadvantaged subgroups.

Abstract
There have been notable improvements in survival over the past 2 decades for gastrointestinal (GI) cancer. However, the degree of improvement by age, race, and sex remains unclear. We analyzed data from 9 population-based cancer registries included in the SEER program of the National Cancer Institute (SEER 9) in 1990 to 2009 (n = 288,337). The degree of survival improvement over time by age, race, and sex was longitudinally measured. From 1990 to 2009, improvements in survival were greater for younger age groups. For patients aged 20 to 49 years and diagnosed from 2005 to 2009, adjusted HRs (95% CIs) were 0.74 (95% CI, 0.66-0.83), 0.49 (95% CI, 0.37-0.64), 0.69 (95% CI, 0.65-0.76), 0.62 (95% CI, 0.54-0.69), and 0.56 (95% CI, 0.42-0.76), for cancer of the stomach, small intestine, colon, rectum and anus, respectively, compared with the same age groups of patients diagnosed during 1990 to 1994. Compared with African Americans, whites experienced greater improvement in small intestinal and anal cancer survival. Female anal cancer and regional anal cancer patients experienced no improvement. Our data suggest that different improvement in survival in age, sex and race exists.

Abstract
A better understanding of factors associated with early death and survival among children, adolescents and young adults with acute myeloid leukaemia (AML) may guide health policy aimed at improving outcomes in these patients. We examined trends in early death and survival among 3935 patients aged 0-39 years with de novo AML in California during 1988-2011 and investigated the associations between sociodemographic and selected clinical factors and outcomes. Early death declined from 9·7% in 1988-1995 to 7·1% in 2004-2011 (P = 0·062), and survival improved substantially over time. However, 5-year survival was still only 50% (95% confidence interval 47-53%) even in the most recent treatment period (2004-2011). Overall, the main factors associated with poor outcomes were older age at diagnosis, treatment at hospitals not affiliated with National Cancer Institute-designated cancer centres, and black race/ethnicity. For patients diagnosed during 1996-2011, survival was lower among those who lacked health insurance compared to those with public or private insurance. We conclude that mortality after AML remained strikingly high in California and increased with age. Possible strategies to improve outcomes include wider insurance coverage and treatment at specialized cancer centres.

Abstract
PURPOSE Patients with cancer are more likely to file for bankruptcy than the general population, but the impact of severe financial distress on health outcomes among patients with cancer is not known. METHODS We linked Western Washington SEER Cancer Registry records with federal bankruptcy records for the region. By using propensity score matching to account for differences in several demographic and clinical factors between patients who did and did not file for bankruptcy, we then fit Cox proportional hazards models to examine the relationship between bankruptcy filing and survival. RESULTS Between 1995 and 2009, 231,596 persons were diagnosed with cancer. Patients who filed for bankruptcy (n = 4,728) were more likely to be younger, female, and nonwhite, to have local- or regional- (v distant-) stage disease at diagnosis, and have received treatment. After propensity score matching, 3,841 patients remained in each group (bankruptcy v no bankruptcy). In the matched sample, mean age was 53.0 years, 54% were men, mean income was $49,000, and majorities were white (86%), married (60%), and urban (91%) and had local- or regional-stage disease at diagnosis (84%). Both groups received similar initial treatments. The adjusted hazard ratio for mortality among patients with cancer who filed for bankruptcy versus those who did not was 1.79 (95% CI, 1.64 to 1.96). Hazard ratios varied by cancer type: colorectal, prostate, and thyroid cancers had the highest hazard ratios. Excluding patients with distant-stage disease from the models did not have an effect on results. CONCLUSION Severe financial distress requiring bankruptcy protection after cancer diagnosis appears to be a risk factor for mortality. Further research is needed to understand the process by which extreme financial distress influences survival after cancer diagnosis and to find strategies that could mitigate this risk.

Abstract
BACKGROUND We previously demonstrated disparate acute myelogenous leukemia (AML) survival for black and Hispanic patients; these differences persisted despite younger ages and higher prevalence of favorable cytogenetics in these groups. This study determined: (i) whether there are differences in treatment delivered to minorities, and (ii) how these differences affect outcomes in AML. We hypothesize that differences in treatment explain some proportion of survival disparities. METHODS We used California Cancer Registry data linked to hospital discharge abstracts for patients with AML (1998-2008). Logistic regression models estimated odds of treatment (chemotherapy and/or hematopoietic stem cell transplant) by race/ethnicity. Cox proportional hazard models estimated mortality by race after adjustment for treatment. RESULTS We analyzed 11,084 records. Black race was associated with lower odds of chemotherapy [OR, 0.74; 95% confidence interval (CI), 0.61-0.91]. Black and Hispanic patients had decreased odds of transplant [(OR, 0.64; 95% CI, 0.46-0.87); (OR, 0.74; 95% CI, 0.62-0.89), respectively]. Black patients had increased hazard of mortality (HR, 1.14; 95% CI, 1.04-1.25) compared with whites. Adjustment for receipt of any treatment resulted in decreased mortality (HR, 1.09; 95% CI, 1.00-1.20) for black patients. CONCLUSIONS AML treatment differences for black patients explain some proportion of the disparity. Future AML disparities studies should investigate socioeconomic and other characteristics. IMPACT Study findings may better elucidate drivers of disparities in AML.

Abstract
Survivin is one of the most important members of the inhibitors of apoptosis protein family, as it is expressed in most human cancers but is absent in normal, differentiated tissues. Lending to its importance, survivin has proven associations with apoptosis and cell cycle control, and has more recently been shown to modulate the tumor microenvironment and immune evasion as a result of its extracellular localization. Upregulation of survivin has been found in many cancers including breast, prostate, pancreatic, and hematological malignancies, and it may prove to be associated with the advanced presentation, poorer prognosis, and lower survival rates observed in ethnically diverse populations.

Abstract
PURPOSE Improvement in US survival rates among adolescents and young adults (AYAs, ages 15 through 39 years inclusive) diagnosed with non-Hodgkin lymphoma (NHL) has been documented over the last two decades. We examined national trends in survival disparities for AYAs with NHL by race/ethnicity and socioeconomic status (SES, county-level poverty) to further understand NHL and to begin monitoring health outcome disparities for this disease. METHODS Surveillance Epidemiology and End Results data were used to calculate 5-year relative survival rates of AYAs diagnosed with NHL from 1992 to 2007 and followed through 2011. Absolute and relative disparities were computed using HD*Calc. Whether a significant linear trend was present was evaluated using Joinpoint. Analyses were replicated after excluding individuals with known HIV infection. RESULTS The study sample included 9,573 total and 7,121 non-HIV cases of NHL. Five-year survival rates improved for all groups over time. Significant decreases were found in absolute disparities for race/ethnicity (non-HIV), in relative disparities for SES (total) and race/ethnicity (total and non-HIV) (all p < 0.05). Survival rates of non-Hispanic Blacks and Hispanics remained below than those of non-Hispanic Whites throughout the time period. CONCLUSION Absolute and relative disparities in 5-year survival narrowed for AYAs with NHL over the time period. To continue to promote this trend, future research should investigate factors, particularly diagnostic delays and barriers to care, which continue to contribute to SES and racial/ethnic differences in survival. These factors may be particularly relevant to identify given the recent Affordable Care Act, which is designed to increase access to medical services, particularly for young adults.

Abstract
BACKGROUND New treatment options and supportive care measures have greatly improved survival of patients with non-Hodgkin lymphoma (NHL) but may not be affordable for those with no insurance or inadequate insurance. METHODS Using data from the Surveillance, Epidemiology, and End Results database, we estimated overall and cause-specific survival according to insurance status within 3 years after diagnosis of patients diagnosed with NHL in the U.S. in the period 2007-2011. Because NHL is a heterogeneous condition, we also examined survival in diffuse large B-cell lymphoma (DLBCL). RESULTS Survival was higher for patients with non-Medicaid insurance compared with either uninsured patients or patients with Medicaid. For patients with any NHL, the 3-year survival estimates were 68.0% for uninsured patients, 60.7% for patients with Medicaid, and 84.9% for patients with non-Medicaid insurance. Hazard ratios (HRs) for uninsured and Medicaid-only patients compared with insured patients were 1.92 (95% confidence interval [CI]: 1.76-2.10) and 2.51 (95% CI: 2.36-2.68), respectively. Results were similar for patients with DLBCL, with survival estimates of 68.5% for uninsured patients (HR: 1.78; 95% CI: 1.57-2.02), 58%, for patients with Medicaid (HR: 2.42; 95% CI: 2.22-2.64), and 83.3% for patients with non-Medicaid insurance. Cause-specific analysis showed survival estimates of 80.3% for uninsured patients (HR: 1.83; 95% CI: 1.62-2.05), 77.7% for patients with Medicaid (HR: 2.23; 95% CI: 2.05-2.42), and 90.5% for patients with non-Medicaid insurance. CONCLUSION Lack of insurance and Medicaid only were associated with significantly lower survival for patients with NHL. Further evaluation of the reasons for this disparity and implementation of comprehensive coverage for medical care are urgently needed.

Abstract
BACKGROUND Lower levels of global DNA methylation in tissue and blood have been associated with increased cancer risk. Conversely, cross-sectional analyses of healthier lifestyle patterns have been associated with higher levels of global DNA methylation. OBJECTIVE In this trial, we explored the associations between changes in lifestyle modifications (diet, weight loss), metabolic markers, and global epigenetic biomarkers in white blood cells. METHODS Study participants were Hispanic, African American, and Afro-Caribbean overweight and sedentary female breast cancer survivors (n = 24) who participated in a larger randomized, crossover, pilot study of a 6-mo weight loss intervention and who had available blood specimens. Anthropometric measures, a food-frequency questionnaire, and peripheral blood were collected at baseline, 6 mo, and 12 mo. Plasma samples were analyzed for metabolic markers (insulin, glucose). We measured DNA methylation of long interspersed nucleotide element 1 (LINE-1) and satellite 2 by pyrosequencing and MethyLight, respectively, and global DNA methylation by the luminometric methylation assay (LUMA). RESULTS DNA methylation of LINE-1 was statistically significantly elevated at 6 mo [75.5% vs. 78.5% (P < 0.0001)] and 12 mo [75.5% vs. 77.7% (P < 0.0001)], compared to baseline. Over a 12-mo period, changes in percentage body fat and plasma glucose concentrations were positively associated with LINE-1 DNA methylation (β = 0.19, P = 0.001) and LUMA DNA methylation levels (β = 0.24, P = 0.02), respectively. Similarly, 12-mo changes in dietary measures such as vegetable (β = 0.009, P = 0.048), protein (β = 0.04, P = 0.001), and total caloric (β = 0.05, P = 0.01) intake were positively associated with changes in LUMA DNA methylation, as was intake of fruit positively associated with changes in LINE-1 DNA methylation (β = 0.004, P = 0.02). CONCLUSIONS Our hypothesis-generating results suggest that lifestyle modifications may be associated with changes in global DNA methylation detectable at 6 and 12 mo. These biomarkers may be useful intermediate biomarkers to use in future intervention trials. This trial was registered at clinicaltrials.gov as NCT00811824.

Abstract
Incidence and relative survival of myeloma by ethnic group was estimated using data from cancer registries in England (2002-2008). Multiple imputation was used to address missing ethnicity data. In total 24 361 cases of myeloma were identified. Age-standardized incidence rate (ASIR) (per 100 000) was higher in the Black ethnic category at 15.00 (95% confidence interval [CI] 13.50-16.40), than amongst South Asians (ASIR = 5.45, 95% CI 4.76-6.14) or the White group (ASIR = 6.11, 95% CI 6.00-6.22). There was a lower risk of death in the Black group for both 1- and 3-year survival (hazard ratio [HR]1 year = 0.66, 95% CI 0.55-0.79; HR3 year = 0.69, 95% CI 0.58-0.83) and South Asians at 1, 3 and 5 years (HR1 year = 0.65, 95% CI 0.51-0.82; HR3 year = 0.72, 95% CI I 0.57-0.90; HR5 year = 0.68, 95% CI 0.50-0.92) when compared to the White population. Further study of differences in myeloma and precursor biology between population groups is important.

Racial differences in three major NHL subtypes: descriptive epidemiology. Cancer Epidemiol 2015; 39:8-13. [PMID: 25560974 DOI: 10.1016/j.canep.2014.12.001] [Citation(s) in RCA: 75] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2014] [Revised: 11/08/2014] [Accepted: 12/07/2014] [Indexed: 01/12/2023]
Abstract
BACKGROUND NHL (non-Hodgkin lymphoma) consists of over 60 subtypes, ranging from slow-growing to very aggressive. The three largest subtypes are DLBCL (diffuse large B-cell lymphoma), FL (follicular lymphoma), and CLL/SLL (chronic lymphocytic leukemia/small lymphocytic lymphoma). For each subtype, different racial groups have different presentations, etiologies, and prognosis patterns. METHODS SEER (Surveillance, Epidemiology, and End Results) data on DLBCL, FL, and CLL/SLL patients diagnosed between 1992 and 2010 were analyzed. Racial groups studied included NHW (non-Hispanic whites), HW (Hispanic whites), blacks, and API (Asians and Pacific Islanders). Patient characteristics, age-adjusted incidence rate, and survival were compared across races. Stratification and multivariate analysis were conducted. RESULTS There are significant racial differences for patients' characteristics, including gender, age at diagnosis, stage, lymph site, and age, and the patterns vary across subtypes. NHWs have the highest incidence rates for all three subtypes, followed by HWs (DLBCL and FL) and blacks (CLL/SLL). The dependence of the incidence rate on age and gender varies across subtypes. For all three subtypes, NHWs have the highest five-year relative survival rates, followed by HWs. When stratified by stage, racial difference is significant in multiple multivariate Cox regression analyses. CONCLUSIONS Racial differences exist among DLBCL, FL, and CLL/SLL patients in the U.S. in terms of characteristics, incidence, and survival. The patterns vary across subtypes. More data collection and analysis are needed to more comprehensively describe and interpret the across-race and subtype differences.

Racial disparity in breast cancer survival: the impact of pre-treatment hematologic variables. Cancer Causes Control 2014; 26:45-56.

Abstract
PURPOSE A survival disparity of black versus white breast cancer patients has been extensively documented but not adequately explained. Blacks and whites also have significant differences in hematologic traits including hemoglobin (HGB). However, a link between survival disparity and hematologic differences has not been reported. We aimed to explore the effect of pre-treatment hematologic variables on this survival disparity. METHODS We sequentially matched 443 black patients, using a minimum distance approach, to four different sets of 443 whites on demographics (age, year of diagnosis, smoking, and drinking status), tumor presentation (all demographic variables plus tumor stage, grade, and hormone receptor status), treatment (all presentation variables plus surgery, chemotherapy, radiation therapy, and hormone therapy), and presentation plus pre-treatment hematologic variables. Racial survival for each matched dataset was analyzed by Cox proportional hazards model. RESULTS We found that white patients matched on demographic characteristics had more favorable survival than blacks [hazard ratio (HR) 0.57, 95 % confidence interval (CI) 0.42-0.77, p log-rank = 0.0002]. Presentation match diminished this disparity [HR 0.72 (0.54-0.95), p log-rank = 0.0199], which was not further reduced in treatment match [HR 0.73 (0.55-0.96), p log-rank = 0.0249]. However, the survival disparity was largely reduced when pre-treatment level of HGB or red blood cell distribution width was further matched in addition to presentation match [HR 0.83 (0.64-1.09), p log-rank = 0.1819 and HR 0.83 (0.64-1.09), p log-rank = 0.1760, respectively]. CONCLUSIONS We found that in our patient population, differences in tumor presentation and certain pre-treatment hematologic traits, but not treatment, were associated with the survival disparity between black and white breast cancer patients.

Abstract
Background MCL (mantle cell lymphoma) is a rare subtype of NHL (non-Hodgkin lymphoma) with mostly poor prognosis. Different races have different etiology, presentation, and progression patterns. Methods Data were analyzed on MCL patients in the United States reported to the SEER (Surveillance, Epidemiology, and End Results) database between 1992 and 2009. SEER contains the most comprehensive population-based cancer information in the U.S., covering approximately 28% of the population. Racial groups analyzed included non-Hispanic whites, Hispanic whites, blacks, and Asians/PIs (Pacific Islanders). Patient characteristics, age-adjusted incidence rate, and survival rate were compared across races. Stratification by age, gender, and stage at diagnosis was considered. Multivariate analysis was conducted on survival. Results In the analysis of patients’ characteristics, distributions of gender, marital status, age at diagnosis, stage, and extranodal involvement were significantly different across races. For all three age groups and both male and female, non-Hispanic whites have the highest incidence rates. In the analysis of survival, for cancers diagnosed in the period of 1992–2004, no significant racial difference is observed. For cancers diagnosed in the period of 1999–2004, significant racial differences exist for the 40–64 age group and stage III and IV cancers. Conclusions Racial differences exist among MCL patients in the U.S. in terms of patients’ characteristics, incidence, and survival. More extended data collection and analysis are needed to more comprehensively describe and understand the racial differences.

Disparities in perceived unmet need for supportive services among patients with lung cancer in the Cancer Care Outcomes Research and Surveillance Consortium. Cancer 2014; 120:3178-91.

Abstract
BACKGROUND The authors investigated the prevalence, determinants of, and disparities in any perceived unmet need for 8 supportive services (home nurse, support group, psychological services, social worker, physical/occupational rehabilitation, pain management, spiritual counseling, and smoking cessation) by race/ethnicity and nativity and how it is associated with perceived quality of care among US patients with lung cancer. METHODS Data from a multiregional, multihealth system representative cohort of 4334 newly diagnosed patients were analyzed. Binomial logistic regression models adjusted for patient clustering. RESULTS Patients with any perceived unmet need (9% overall) included 7% of white-US-born (USB), 9% of white-foreign-born (FB), 13% of black-USB, 8% of Latino-USB, 24% of Latino-FB, 4% of Asian/Pacific Islander (API)-USB, 14% of API-FB, and 11% of "other" patients (P < .001). Even after controlling for demographic and socioeconomic factors, health system and health care access, and need, black-USB, Latino-FB, and Asian-FB patients were more likely to perceive an unmet need than white-USB patients by 5.1, 10.9, and 5.6 percentage points, respectively (all P < .05). Being younger, female, never married, uninsured, a current smoker, or under surrogate care or having comorbidity, anxiety/depression, or a cost/insurance barrier to getting tests/treatments were associated with any unmet need. Patients with any unmet need were more likely to rate care as less-than-"excellent" by 13 percentage points than patients with no unmet need (P < .001). CONCLUSIONS Significant disparities in unmet supportive service need by race/ethnicity and nativity highlight immigrants with lung cancer as being particularly underserved. Eliminating disparities in access to needed supportive services is essential for delivering patient-centered, equitable cancer care.

J Cancer Surviv 2014; 8:580-94.

Abstract
BACKGROUND Treatment summary and survivorship care plan studies are at the forefront of research priorities with precedence for ethnic minority inclusion. This preliminary study joined the advocacy, scientific, and medical communities to inform the development and evaluation of the Treatment Summary and Survivorship Care Plan (TSSCP-S) template targeted for Latino breast cancer patients (LCA). METHODS The development of the TSSCP-S began as modifications to the American Society of Cancer Oncology (ASCO) (TSSCP-ASCO) template via a transcreation process informed by 12 LCA survivors/advocates, and evaluated by 10 survivor/advocates and health professionals. The TSSCP-S template development was guided by the Shared Care, Psychooncology Models, and Contextual Model of Health Related Quality of Life. RESULTS The bilingual TSSCP-S was independently evaluated by bilingual, survivor/advocates, and health professionals (n = 10). Preliminary analyses indicate that the TSSCP-S template was rated more favorably than the TSSCP-ASCO on the following domains: content (p = 0.02), clarity (p = 0.02), utility (p = 0.04), cultural and linguistic responsiveness (p = 0.03), and socioecological responsiveness (p = 0.01). Evaluators noted that the TSSCP-S template was more patient-centered, and endorsed the acceptability as well as the potential utility and applicability of the bilingual TSSCP-S template to appropriately guide surveillance and follow-up care. CONCLUSIONS Our findings indicate that the TSSCP-S achieved clinical, cultural, and linguistic responsiveness relevant to Latinos. Patient-centered TSSCP that are presented in a bilingual format are necessary to achieve the intended goals of TSSCP including appropriate patient information, education, and resources pertaining to their treatment, potential side effects, and recommended surveillance and follow-up care for English language limited patients. Additionally, our culturally responsive TSSCP-S development framework offers a model for TSSCP template development for targeted and underserved populations, including ethnic and linguistic minority cancer survivors. IMPLICATIONS FOR CANCER SURVIVORS These data support the development and evaluation of a TSSCP targeted to an underserved, high-risk population, LCAs. Identifying methods to improve surveillance and follow-up guideline adherence may lead to improved clinical cancer outcomes and quality of life.

Abstract
BACKGROUND Veterans Affairs (VA) manages the largest US integrated health care system. Although quality of VA colorectal cancer (CRC) care is well chronicled, there is a paucity of research examining racial differences in this care. This study examines racial differences in 2 dimensions of quality of VA CRC care: processes (time to treatment) and outcomes (survival). PATIENTS AND METHODS Retrospective data were from the VA External Peer Review Program (EPRP), a nationwide VA quality-monitoring program. Study patients were white and African American men diagnosed with nonmetastatic CRC between 2003 and 2006 who received definitive CRC surgery. We examined 3 quality indicators: time from (1) surgery to initiation of adjuvant chemotherapy (stages II-III disease), (2) surgery to surveillance colonoscopy (stages I-III disease), and (3) surgery to death (stages I-III disease). Unadjusted analyses used log-rank and Wilcoxon tests. Adjusted analyses used Cox proportional hazard models. RESULTS In unadjusted analyses, there was no evidence of racial differences across the 3 quality measures. In adjusted Cox regression, there were no racial differences in time to initiation of chemotherapy (hazard ratio [HR], 0.82; P = .61) or surgery to death (HR, 0.94; P = .49). In adjusted Cox regression, among those receiving colonoscopy within 7 to 18 months after surgery, white patients experienced slightly shorter median times to surveillance colonoscopy than did African American patients (367 vs. 383 days; HR, 0.63; P = .02). CONCLUSION Other than a small racial difference in timing of surveillance colonoscopy, there was little evidence of racial differences in quality of CRC care among VA health care system users.

Abstract
This study provides up-to-date and detailed cancer survival estimates of German patients with non-Hodgkin lymphoma (NHL, International Statistical Classification of Diseases 10th Revision [ICD-10] codes C82-C85) based on data from 11 cancer registries. Period analysis was used to calculate 5-year relative survival in 2002-2006, overall and by gender, age and histology. Comparison was made with patients with NHL in the United States (US) Surveillance, Epidemiology and End Results database in the same time period. Overall 5-year relative survival for patients with NHL in Germany in 2002-2006 was 62.8% and in the US was 65.1%. Survival decreased with age from 81.7% at age 15-49 to 46.5% at age 75+. Survival in the US was 75.3% at age 15-49 and 52% at age 75+. Survival was higher for women than for men, at 65.2% for women and 60.7% for men. Survivals for diffuse B-cell lymphoma and follicular lymphoma, the two most common subtypes of NHL, were 57.3% and 77.5%, respectively. Between 2002 and 2006, overall 5-year relative survival increased by 5.3 percentage points. We conclude that survival for NHL is increasing in Germany in recent years. Survival was higher in Germany than in the US for patients aged 15-49 but lower for older patients.

Abstract
The survival of younger patients with acute leukemia has improved in the early 21(st) century, but it is unknown whether people of all ethnic and racial backgrounds have benefited equally. Using cancer registry data from the Surveillance, Epidemiology and End Results Program, we assessed trends in 5-year relative survival for patients aged 15 years or more with acute lymphoblastic leukemia and acute myeloblastic leukemia divided by racial and ethnic group, including non-Hispanic whites, African-Americans, Hispanics, and Asian-Pacific Islanders in the 1990s and the early 21(st) century. Modeled period analysis was used to obtain the most up-to-date estimates of survival. Overall, the 5-year survival increased from 31.6% in 1997-2002 to 39.0% in 2003-2008 for patients with acute lymphoblastic leukemia and from 15.5% in 1991-1996 to 22.5% in 2003-2008 for those with acute myeloblastic leukemia. Nevertheless, among patients with acute lymphoblastic leukemia, age-adjusted 5-year relative survival rates remained lower for African-Americans and Hispanics than for non-Hispanic whites. Among patients with acute myeloblastic leukemia, the increase in survival was greatest (from 32.6% in 1991-1996 to 47.1% in 2003-2008) for younger patients (15-54 years), and was more pronounced for non-Hispanic whites (+16.4% units) than for other patients (+10.8% units). Increases in survival are observed in all ethnic or racial groups. Nevertheless, among patients with acute leukemias, disparities in survival persist between non-Hispanic white people and people of other ethnic or racial groups. Disparities are increasing in younger patients with acute myeloblastic leukemia. Improvements in access to treatment, especially for minority patients, may improve outcomes.
