RESUMEN
BACKGROUND: Despite Medicare coverage, financial hardship is a prevalent issue among those diagnosed with cancer at age 65 years and older, particularly among those belonging to a racial or ethnic minority group. Sociodemographic, clinical, and area-level factors may mediate this relationship; however, no studies have assessed the extent to which these factors contribute to the racial/ethnic disparities in financial hardship. METHODS: Surveys assessing financial hardship were completed by 721 White (84%) or Black (16%) patients (aged 65 years and older) who were diagnosed with breast (34%), prostate (27%), lung (17%), or colorectal (14%) cancer or lymphoma (9%) at the University of Alabama at Birmingham between 2000 and 2019. Financial hardship included material, psychological, and behavioral domains. Nonlinear Blinder-Oaxaca effect decomposition methods were used to evaluate the extent to which individual and area-level factors contribute to racial disparities in financial hardship. RESULTS: Black patients reported lower income (65% vs. 34% earning <$50,000) and greater scores on the Area Deprivation Index (median, 93.0 vs. 55.0). Black patients reported significantly higher rates of overall (39% vs. 18%), material (29% vs. 11%), and psychological (27% vs. 11%) hardship compared with White patients. Overall, the observed characteristics explained 51% of racial differences in financial hardship among cancer survivors, primarily because of differences in income (23%) and area deprivation (11%). CONCLUSIONS: The current results identify primary contributors to racial disparities in financial hardship among older cancer survivors, which can be used to develop targeted interventions and allocate resources to those at greatest risk for financial hardship.
RESUMEN
OBJECTIVE: To understand the mediating effect of socioeconomic factors on the association between residential segregation and racial disparities in pancreatic cancer (PC). BACKGROUND: Black patients with PC present at a later stage and have worse mortality than White patients. These disparities have been explained by the level of residential segregation. METHODS: Data were obtained from Surveillance, Epidemiology, and End-Results (SEER) and included all Black and White patients who were diagnosed with PC between 2005 and 2015. The primary exposure variable was the Index of Dissimilarity, a validated measure of segregation. County-level socioeconomic variables from the US Census were assessed as mediators. The primary outcomes were advanced stage at diagnosis, surgical resection for localized disease, and overall mortality. Generalized structural equation modeling was used to assess the mediation of each of the socioeconomic variables. RESULTS: Black patients in the highest levels of segregation saw a 12% increased risk [relative risk=1.12; 95% confidence interval (CI): 1.08, 1.15] of presenting at an advanced stage, 11% decreased likelihood of undergoing surgery (relative risk=0.89; 95% CI: 0.83, 0.94), and 8% increased hazards of death (hazard ratio=1.08; 95% CI: 1.03, 1.14) compared with White patients in the lowest levels. The Black share of the population, insurance status, and income inequality mediated 58% of the total effect on the advanced stage. Poverty and Black income immobility mediated 51% of the total effect on surgical resection. Poverty and Black income immobility mediated 50% of the total effect on overall survival. CONCLUSIONS: These socioeconomic factors serve as intervention points for legislators to address the social determinants inherent to the structural racism that mediate poor outcomes for Black patients.

OBJECTIVE: To determine the effect of persistent poverty on the diagnosis, surgical resection and survival of patients with non-small cell lung (NSCLC), breast, and colorectal cancer. BACKGROUND: Disparities in cancer outcomes exist in counties with high levels of poverty, defined as ≥20% of residents below the federal poverty level. Despite this well-established association, little is known about how the duration of poverty impacts cancer care and outcomes. One measure of poverty duration is that of "persistent poverty," defined as counties in high poverty since 1980. METHODS: In this retrospective cohort study, patients with NSCLC, breast and colorectal cancer were identified from SEER (2012-2016). County-level poverty was obtained from the American Community Survey (1980-2015). Outcomes included advanced stage at diagnosis (stage III-IV), resection of localized disease (stage I-II) and cancer-specific survival. Hierarchical generalized linear models and accelerated failure time models with Weibull distribution were used, adjusted for patient-level covariates and region. RESULTS: Overall, 522,514 patients were identified, of which 5.1% were in persistent poverty. Patients in persistent poverty were more likely to present with advanced disease [NSCLC odds ratio (OR): 1.12, 95% confidence interval (CI): 1.06-1.18; breast OR: 1.09, 95% CI: 1.02-1.17; colorectal OR: 1.00, 95% CI: 0.94-1.06], less likely to undergo surgery (NSCLC OR: 0.81, 95% CI: 0.73-0.90; breast OR: 0.82, 95% CI: 0.72-0.94; colorectal OR: 0.84, 95% CI: 0.70-1.00) and had increased cancer-specific mortality (NSCLC HR: 1.09, 95% CI: 1.06-1.13; breast HR: 1.18, 95% CI: 1.05-1.32; colorectal HR: 1.09, 95% CI: 1.03-1.17) as compared with those without poverty. These differences were observed to a lesser magnitude in counties with current, but not persistent, poverty and disappeared in counties no longer in poverty. CONCLUSIONS: The duration of poverty has a direct impact on cancer-specific outcomes, with the greatest effect seen in persistent poverty and resolution of disparities when a county is no longer in poverty. Policy focused on directing resources to communities in persistent poverty may represent a possible strategy to reduce disparities in cancer care and outcomes.

Individuals diagnosed with cancer as adolescents and young adults (AYAs; ages 15-39 years) face unique vulnerabilities. Compared with individuals diagnosed when younger (≤14 years) or older (≥40 years), AYAs have not seen the same improvement in survival. Furthermore, they sit at a complex moment of social, emotional, and cognitive development, and have a unique interface with the healthcare system. With these observations, NCI prioritized addressing the unique vulnerabilities among AYAs with cancer, and NCCN developed guidelines regarding optimal AYA cancer care. Improvements in certain locales have been seen in the wake of this focus on AYAs, suggesting that continuing to consider AYA outcomes in the context of their specific needs is critical as we strive toward additional improvements. However, it is key to consider the drivers of these outcomes to continue this trajectory. This review presents a holistic conceptual model that includes factors that influence outcomes among AYAs with cancer, including domains in these levels that influence both clinical outcomes (such as relapse and survival) and health-related quality of life (HRQoL). These include domains at the patient level, such as social constructs (race/ethnicity, socioeconomic status), behavior (adherence, risk-taking), biologic characteristics (cancer biology, host genetics), medical treatment (treatment regimen, risk-based survivorship care), and treatment-related toxicities. The model also includes domains at the system level, which include treatment location (NCI designation, facility model, AYA program presence), clinical trial enrollment, transdisciplinary communication, fertility preservation, and psychosocial support. Recognizing these multiple factors at the level of the individual and the healthcare system influence AYA outcomes (from HRQoL to survival), it is key not only to consider patient-level interventions and development of novel cancer agents but also to develop systems-level interventions that can be executed in parallel. In this way, the impact can be expanded to a vast number of AYAs.

INTRODUCTION: Patients with pancreatic cancer can present with a variety of insidious abdominal symptoms, complicating initial diagnosis. Early symptoms of pancreatic cancer often mirror those associated with gallstone disease, which has been demonstrated to be a risk factor for this malignancy. This study aims to compare the incidence of gallstone disease in the year before diagnosis of pancreatic ductal adenocarcinoma (PDAC) as compared to the general population, and evaluate the association of gallstone disease with stage at diagnosis and surgical intervention. METHODS: Patients with PDAC were identified from SEER-Medicare (2008-2015). The incidence of gallstone disease (defined as cholelithiasis, cholecystitis and/or cholecystectomy) in the 1 year before cancer diagnosis was compared to the annual incidence in an age-matched, sex-matched, and race-matched noncancer Medicare cohort. RESULTS: Among 14,654 patients with PDAC, 4.4% had gallstone disease in the year before cancer diagnosis. Among the noncancer controls (n = 14,654), 1.9% had gallstone disease. Both cohorts had similar age, sex and race distributions. PDAC patients with gallstone disease were diagnosed at an earlier stage (stage 0/I-II, 45.8% versus 38.1%, P < 0.0001) and a higher proportion underwent resection (22.7% versus 17.4%, P = 0.0004) compared to patients without gallstone disease. CONCLUSIONS: In the year before PDAC diagnosis, patients present with gallstone disease more often than the general population. Improving follow-up care and differential diagnosis strategies may help combat the high mortality rate in PDAC by providing an opportunity for earlier stage of diagnosis and earlier intervention.

BACKGROUND: Patients with lymphoma have an increased risk of venous thromboembolism (VTE). The authors examined the risk of VTE and subsequent health care utilization in elderly patients with diffuse large B cell lymphoma (DLBCL). METHODS: A total of 5537 DLBCL patients ≥66 years old enrolled in Medicare from the Surveillance, Epidemiology, and End Results registry and a noncancer control group of Medicare beneficiaries (n = 5537) were identified. Cumulative incidence function to examine the risk of VTE 12 months after DLBCL diagnosis was used. Fine and Gray method was used to examine the risk factors associated with VTE risk in multivariable models. Total number of hospitalizations, outpatient visits, and Medicare spending were compared in DLBCL patients with and without VTE. RESULTS: VTE was diagnosed in 8.3% DLBCL patients and 1.5% controls, yielding an 8.6-fold higher risk of VTE in DLBCL in adjusted analysis (95% confidence interval [CI], 6.62-11.20; P < .001). Multivariable regression analysis showed that precancer VTE history was associated with an increased risk of developing VTE after a DLBCL diagnosis (hazard ratio [HR], 5.39; 95% CI, 4.39-6.63), and Asian individuals were associated with a lower risk (HR, 0.54; 95% CI, 0.29-1.00). Patients newly diagnosed with VTE after lymphoma had a 1.7-fold higher rate of hospitalization and a 1.2-fold higher rate of outpatient visits compared to those without, resulting in excess Medicare spending of $22,208 in the first year after DLBCL diagnosis. CONCLUSIONS: Elderly patients with DLBCL have an elevated risk of VTE resulting in excess health care utilization. VTE history before DLBCL was associated with increased risk of post-DLBCL VTE, and Asian individuals were associated with a lower risk of VTE.

BACKGROUND: Poor self-rated health (SRH) is a known predictor of frailty and mortality in the general population; however, its role among older adults with cancer is unknown. We evaluated the role of SRH as a potential screening tool to identify frailty and geriatric assessment (GA)-identified impairments. MATERIALS AND METHODS: Adults ≥60 years diagnosed with cancer in the UAB Cancer & Aging Resilience Evaluation (CARE) registry underwent a GA at the time of initial consultation. We measured SRH using a single-item from the Patient-Reported Outcomes Measurement Information System global health scale and dichotomized responses as poor (poor, fair) and good (good, very good, and excellent). We evaluated the diagnostic performance of SRH in measuring frailty, and GA impairment (≥2 deficits among a set of seven GA domains). We examined the impact of SRH with survival using a Cox model adjusting for confounders, exploring the mediating role of frailty. RESULTS: Six hundred and three older adults with cancer were included, with a median age of 69 years. Overall, 45% (n = 274) reported poor SRH. Poor SRH demonstrated high sensitivity and specificity for identifying frailty (85% and 78%, respectively) and GA impairment (75% and 78%, respectively). In a Cox regression model, poor SRH was associated with inferior survival (HR = 2.26; 95% CI 1.60-3.18) after adjusting for confounders; frailty mediated 69% of this observed relationship. CONCLUSION: Self-rated health may be used as a screening tool to identify older adults with cancer with frailty and GA impairments. Poor SRH is associated with inferior survival, which is mediated by frailty.

BACKGROUND: Expedited or delayed surgery for colon cancer without appropriate work-up increases mortality risk. We sought to identify what patient, social, and hospital factors were associated with timely, guideline-adherent work-up for colon cancer. METHODS: Retrospective analysis of 19,046 patients in the Surveillance, Epidemiology, and End Results (SEER) database linked with Medicare administrative claims who underwent elective surgery for colon cancer between 2010 and 2015 was performed. Primary outcome was receipt of complete preoperative work-up (colonoscopy, imaging, tumor marker evaluation) and timely surgery within 60 days of diagnosis. Patients were stratified into four groups: (1) adherent; (2) early surgery (< 30 days) with incomplete work-up; (3) surgery between 30 and 60 days with incomplete work-up; and (4) late surgery (> 60 days) with/without work-up. Characteristics were compared and multinomial logistic regression was performed. RESULTS: Overall, 46.2% of patients received adherent care, 33.1% had early surgery and inadequate work-up, 10.3% had appropriately timed surgery but incomplete work-up, and 10.4% underwent late surgery. Multivariable analysis demonstrated that older, female, Black, and unmarried patients as well as patients living in areas with higher rates of poverty were more likely to receive non-adherent care. A greater proportion of patients at teaching hospitals received complete work-up (57.6% vs. 49.5%) but also underwent late surgery (12.4% vs. 8.6%) compared with non-teaching hospitals. CONCLUSIONS: Patient, societal, and hospital factors impact whether patients receive guideline-adherent colon cancer care. Interventions are needed to improve access to timely and guideline-adherent cancer care as a possible mechanism to combat surgical disparities.

BACKGROUND: The volume-outcome relationship has been well-established for pancreaticoduodenectomy (PD). It remains unclear if this is primarily driven by hospital volume or individual surgeon experience. OBJECTIVE: This study aimed to determine the relationship of hospital and surgeon volume on short-term outcomes of patients with pancreatic adenocarcinoma undergoing PD. METHODS: Patients >65 years of age who underwent PD for pancreatic adenocarcinoma were identified from the Surveillance, Epidemiology, and End Results (SEER)-Medicare database (2008-2015). Analyses were stratified by hospital volume and then surgeon volume, creating four volume cohorts: low-low (low hospital, low surgeon), low-high (low hospital, high surgeon), high-low (high hospital, low surgeon), high-high (high hospital, high surgeon). Propensity scores were created for the odds of undergoing surgery with high-volume surgeons. Following matching, multivariable analysis was used to assess the impact of surgeon volume on outcomes within each hospital volume cohort. RESULTS: In total, 2450 patients were identified: 54.3% were treated at high-volume hospitals (27.0% low-volume surgeons, 73.0% high-volume surgeons) and 45.7% were treated at low-volume hospitals (76.9% low-volume surgeons, 23.1% high-volume surgeons). On matched multivariable analysis, there were no significant differences in the risk of major complications, 90-day mortality, and 30-day readmission based on surgeon volume within the low and high hospital volume cohorts. CONCLUSION: Compared with surgeon volume, hospital volume is a more significant factor in predicting short-term outcomes after PD. This suggests that a focus on resources and care pathways, in combination with volume metrics, is more likely to achieve high-quality care for patients undergoing PD across all hospitals.

INTRODUCTION: Routine screening plays a critical role in the diagnosis of hepatocellular carcinoma (HCC), but not all patients undergo consistent surveillance. This study aims to evaluate surveillance patterns and their association with diagnosis stage and survival among Medicare patients at risk for HCC. PATIENTS AND METHODS: Patients with HCC and guideline-based screening eligibility who underwent imaging with ultrasound or abdominal magnetic resonance imaging (MRI) in the 2 years prior to diagnosis were identified from SEER-Medicare (2008-2015). Three surveillance cohorts were created: diagnostic (imaging only within 3 months prior), intermittent (imaging only once within 2 years prior, excluding diagnostic), and routine (at least two imaging encounters within 2 years prior, excluding diagnostic). Multivariable logistic regression was used to predict early-stage diagnosis (stage I-II), and 5-year survival was evaluated using the accelerated failure time method with Weibull distribution. RESULTS: Among 2261 eligible patients, 26.1% were classified as diagnostic, 15.8% as intermittent, and 58.1% as routine surveillance. The median age was 74 years (IQR 70-78 years). The majority of patients had a preexisting cirrhosis diagnosis (81.5%). Routine and intermittent, compared with diagnostic, surveillance were predictive of early-stage disease (routine: OR 2.05, 95% CI 1.64-2.56; intermittent: OR 1.43, 95% CI 1.07-1.90). Patients who underwent routine surveillance had significantly lower risk of mortality (HR 0.84, 95% CI 0.75-0.94) compared with the diagnostic group. CONCLUSIONS: A large proportion of screening-eligible patients do not undergo routine surveillance, which is associated with late-stage diagnosis and higher risk of mortality. These findings demonstrate the impact of timely and consistent healthcare access and can guide interventions for promoting surveillance among these patients.

BACKGROUND: Medicaid expansion has led to earlier stage diagnoses in several cancers but has not been studied in hepatocellular carcinoma (HCC), a disease with complex risk factors. We examined the effect of Medicaid expansion on the diagnosis of HCC and associations with county-level social vulnerability. METHODS: Patients with HCC <65 years of age were identified from the SEER database (2010-2016). County-level social vulnerability factors were obtained from the CDC SVI and BRFSS. A Difference-in-Difference analysis evaluated change in early-stage diagnoses (stage I-II) between expansion and non-expansion states. A Difference-in-Difference-in-Difference analysis evaluated expansion impact among counties with higher proportions of social vulnerability. RESULTS: Of 19,751 patients identified, 81.5% were in expansion states. Uninsured status decreased in expansion states (6.3%-2.4%, p < 0.0001) and remained unchanged in non-expansion states (12.7%-14.8%, p = 0.43). There was no significant difference in the incidence of early-stage diagnoses between expansion states and non-expansion states. Results were consistent when accounting for social vulnerability. CONCLUSION: Medicaid expansion was not associated with earlier stage diagnoses in patients with HCC, including those with higher social vulnerability. Unlike other cancers, expanded access did not translate into higher utilization of care in HCC, suggesting barriers on a multitude of levels.

BACKGROUND: Patients undergoing pancreaticoduodenectomy (PD) at low volume PD hospitals with high volume for other complex operations have comparable outcomes to high volume PD centers. We evaluated the impact of upper gastrointestinal operations (UGI) hospital volume on the outcomes of elderly, high risk patients undergoing PD. METHODS: Patients >65 years old who underwent PD for pancreatic adenocarcinoma were identified from SEER-Medicare (2008-2015). Four volume cohorts were created using PD tertiles and UGI median: low (1st tertile PD), mixed-low (2nd tertile PD, low UGI), mixed-high (2nd tertile PD, high UGI) and high (3rd tertile PD). Multivariable logistic and negative binomial regression assessed short-term complications. RESULTS: In total, 2717 patients were identified with a median age of 74.5 years. Patients treated at low, mixed-low and mixed-high volume hospitals, versus high volume, had higher risk of short-term complications, including major complications (low: OR 1.441, 95%CI 1.165-1.783; mixed-low: OR 1.374, 95%CI 1.085-1.740; mixed-high: OR 1.418, 95%CI 1.098-1.832) and 90-day mortality (low: OR 2.16, 95%CI 1.454-3.209; mixed-low: OR 2.068, 95%CI 1.347-3.175; mixed-high: OR 1.96, 95%CI 1.245-3.086). CONCLUSION: Patients with pancreatic adenocarcinoma who are older and more medically complex benefit from undergoing surgery at high volume PD centers, independent of the operative experience of that center.

BACKGROUND: Individuals diagnosed with acute lymphoblastic leukemia (ALL) between the ages of 22 and 39 years experience worse outcomes than those diagnosed when they are 21 years old or younger. Treatment at National Cancer Institute-designated Comprehensive Cancer Centers (CCC) mitigates these disparities but may be associated with higher expenditures. METHODS: Using deidentified administrative claims data (OptumLabs Data Warehouse), the cancer-related expenditures were examined among patients with ALL diagnosed between 2001 and 2014. Multivariable generalized linear model with log-link modeled average monthly health-plan-paid (HPP) expenditures and amount owed by the patient (out-of-pocket [OOP]). Cost ratios were used to calculate excess expenditures (CCC vs non-CCC). Incidence rate ratios (IRRs) compared CCC and non-CCC monthly visit rates. Models adjusted for sociodemographics, comorbidities, adverse events, and months enrolled. RESULTS: Clinical and sociodemographic characteristics were comparable between CCC (n = 160) and non-CCC (n = 139) patients. Higher monthly outpatient expenditures in CCC patients ($15,792 vs $6404; P < .001) were driven by outpatient hospital HPP expenditures. Monthly visit rates and per visit expenditures for nonchemotherapy visits (IRR = 1.6; P = .001; CCC = $8247, non-CCC = $1191) drove higher outpatient hospital expenditures among CCCs. Monthly OOP expenditures were higher at CCCs for outpatient care (P = .02). Inpatient HPP expenditures were significantly higher at CCCs ($25,918 vs $13,881; êµ = 0.9; P < .001) before accounting for adverse events but were no longer significant after adjusting for adverse events (êµ = 0.4; P = .1). Hospitalizations and length of stay were comparable. CONCLUSIONS: Young adults with ALL at CCCs have higher expenditures, likely reflecting differences in facility structure, billing practices, and comprehensive patient care. It would be reasonable to consider CCCs comparable to the oncology care model and incentivize the framework to achieve superior outcomes and long-term cost savings. LAY SUMMARY: Health care expenditures in young adults (aged 22-39 years) with acute lymphoblastic leukemia (ALL) are higher among patients at National Cancer Institute-designated Comprehensive Cancer Centers (CCC) than those at non-CCCs. The CCC/non-CCC differences are significant among outpatient expenditures, which are driven by higher rates of outpatient hospital visits and outpatient hospital expenditures per visit at CCCs. Higher expenditures and visit rates of outpatient hospital visits among CCCs may also reflect how facility structure and billing patterns influence spending or comprehensive care. Young adults at CCCs face higher inpatient HPP expenditures; these are driven by serious adverse events.

OBJECTIVE: We hypothesized colon resection within 30 days of diagnosis of cancer would have higher rates of readmission and cancer specific mortality, unless there was demonstrated evidence of preoperative workup. SUMMARY BACKGROUND DATA: Few studies have examined if negative consequences exist with expedited elective surgery after diagnosis of colon cancer. Surgery in a shorter time frame may result in a lack of appropriate preoperative care. METHODS: Retrospective analysis of 25,407 patients in the Surveillance Epidemiology and End Results registry who underwent elective surgical resection for colon cancer from 2010 to 2015. Cohort stratified by age (66-75 vs >75 years). Primary outcomes of interest were 30-day readmission and 5-year colon cancer specific mortality. Relationships between timing of surgery and outcomes were assessed. RESULTS: On unadjusted analysis, surgery before 20 days of diagnosis was associated with higher risk of 30-day readmission and colon cancer specific mortality in both age groups. Among those age 66 to 75 years old, adjusting for patient factors and preoperative workup eliminated the risk of 30-day readmission (risk ratio 1.5-0.9 for 0-10 days, risk ratio 1.3-0.9 for 11-20 days). However, the risk for colon cancer specific mortality, although reduced, persisted (hazard ratio 2.2-1.3 for 0-10 days, hazard ratio 2.0-1.2 for 11-20 days). In the cohort older than 75 years, adjusting for patient level factors and preoperative workup eliminated risk of surgery 20 days postop or sooner. CONCLUSIONS: The risk associated with short time to surgery (within 30 days) may be mitigated if full oncologic workups are provided.

OBJECTIVE: To understand the role of racial residential segregation on Black-White disparities in breast cancer presentation, treatment, and outcomes. SUMMARY OF BACKGROUND DATA: Racial disparities in breast cancer treatment and outcomes are well documented. Black individuals present at advanced stage, are less likely to receive appropriate surgical and adjuvant treatment, and have lower overall and stage-specific survival relative to White individuals. METHODS: Using data from the Surveillance, Epidemiology, and End Results program, we performed a retrospective cohort study of Black and White patients diagnosed with invasive breast cancer from 2005 to 2015 within the 100 most populous participating counties. The racial index of dissimilarity was used as a validated measure of residential segregation. Multivariable regression was performed, predicting advanced stage at diagnosis (stage III/IV), surgery for localized disease (stage I/II), and overall stage-specific survival. RESULTS: After adjusting for age at diagnosis, estrogen/progesterone receptor status, and region, Black patients have a 49% greater risk (relative risk [RR] 1.49 95% confidence interval [CI] 1.27, 1.74) of presenting at advanced stage with increasing segregation, while there was no observed difference in Whites (RR 1.04, 95% CI 0.93, 1.16). Black patients were 3% less likely to undergo surgical resection for localized disease (RR 0.97, 95% CI 0.95, 0.99) with increasing segregation, while Whites saw no significant difference. Black patients had a 29% increased hazard of death (RR 1.29, 95% CI 1.04, 1.60) with increasing segregation; there was no significant difference among White patients. CONCLUSIONS: Our data suggest that residential racial segregation has a significant association with Black-White racial disparities in breast cancer. These findings illustrate the importance of addressing structural racism and residential segregation in efforts to reduce Black-White breast cancer disparities.

BACKGROUND: Breast cancer survivors are at risk for developing cardiovascular disease due to cardiotoxic cancer treatment. Research on young breast cancer survivors (diagnosed < 45 years old) are limited. METHODS: Young breast cancer survivors diagnosed between age 30 and 44, stage I-III, and treated at the University of Alabama at Birmingham Hospital between 2012 and 2015 were included. Cardiovascular disease risk was estimated using excess heart age (calculated using age, systolic blood pressure, blood pressure medication, diabetes, smoking, body mass index) and examined at two time points: diagnosis and 2-year follow-up. Statistical analyses included within-group mean comparison tests and linear regression to examine predictors of excess heart age. RESULTS: A total of 152 young breast cancer survivors were included; 95 received anthracyclines and/or trastuzumab, and 57 did not. Overall excess heart age was 4.2 at diagnosis and 5.4 years at 2-year follow-up (p = 0.08). Change in excess heart age from diagnosis to 2-year follow-up among those receiving or not receiving anthracyclines and/or trastuzumab was 4.3-4.4 years, p = 0.93; and 4.0-7.1 years, p < 0.01; respectively. Factors that predicted excess heart age included endocrine therapy (p = 0.049) and change from premenopausal to postmenopausal status (p = 0.048). CONCLUSIONS: Anthracyclines and trastuzumab were not predictors of excess heart age. Subclinical changes undetected by heart age may still occur. Future research is needed to evaluate heart age over longer follow-up and to develop a modified heart age tool, that incorporates treatment risk, that facilitates identification of high-risk cancer patients for early intervention in cardiac risk prevention.

BACKGROUND: Disparities in pancreatic cancer outcomes between black and white patients are well documented. This study aimed to use a more novel index to examine the impact of racial segregation on the diagnosis, management, and outcomes of pancreatic cancer in black patients compared with white patients. METHODS: Black and white adults with pancreatic cancer in urban counties were identified using data from the 2018 submission of the Surveillance, Epidemiology and End Results (SEER) Program and the 2010 Census. The racial index of dissimilarity (IoD), a validated proxy of racial segregation, was used to assess the evenness with which whites and blacks are distributed across census tracts in each county. Multivariate Poisson regression was performed, and stepwise models were constructed for each of the outcomes. Overall survival was studied using the Kaplan-Meier method. RESULTS: The study enrolled 60,172 adults with a diagnosis of pancreatic cancer between 2005 and 2015. Overall, the black patients (13.8% of the cohort) lived in more segregated areas (IoD, 0.67 vs 0.61; p < 0.05). They were less likely to undergo surgery for localized disease (relative risk [RR], 0.80; 95% confidence interval [CI], 0.76-0.83) and more frequently had a diagnosis of advanced-stage disease (RR, 1.09; 95% CI, 1.01-1.19) with increasing segregation. They also had shorter survival times (9.8 vs 11.4 months; p < 0.05). CONCLUSIONS: Disparities in advanced-stage disease at diagnosis, surgery for localized disease, and overall survival are directly related to the degree of residential segregation, a proxy for structural racism. In searching for solutions to this problem, it is important to account for the historical marginalization of black Americans.

OBJECTIVES: To examine the effects of racial residential segregation and structural racism on the diagnosis, treatment, and outcomes of patients with prostate cancer. PATIENTS AND METHODS: This retrospective cohort study examined men diagnosed with prostate cancer between 2005 and 2015. We collected data from Black and White men, aged ≥30 years, living within the 100 most populous counties participating in the Surveillance, Epidemiology, and End Results programme, a nationally representative dataset. The racial Index of Dissimilarity, a validated measure of segregation, was the primary exposure of interest. Outcomes of interest included advanced stage at diagnosis (Stage IV), surgery for localised disease (Stage I-II), and 10-year overall and cancer-specific survival. Multivariable Poisson regression analyses with robust error variance estimated the relative risk (RR) of advanced stage at diagnosis and surgery for localised disease at differing levels of segregation. Survival analysis was performed using competing hazards analysis. RESULTS: Multivariable models estimating stage at diagnosis showed that the disparities between Black and White men disappeared at low levels of segregation. Disparities in receiving surgery for localised disease persisted across all levels of segregation. In racially stratified analyses, segregation had no effect on stage at diagnosis or surgical resection for Black patients. White patients saw a 56% (RR 0.42, P < 0.001) reduced risk of presenting at advanced stage and 20% increased likelihood (RR 1.20, P < 0.001) of surgery for localised disease. Black patients in the lowest segregation areas had the lowest overall mortality, but the highest cancer-specific mortality. CONCLUSIONS: Our study provides evidence that residential segregation has a significant impact on Black-White disparities in prostate cancer, likely through improved outcomes for White patients and worse outcomes for Black patients in more segregated areas. These findings suggest that mitigating segregation and the downstream effects of socioeconomic factors could alleviate these disparities.

BACKGROUND: The NCCN Guidelines for Older Adult Oncology recommend that, when possible, older adults with cancer undergo a geriatric assessment (GA) to provide a comprehensive health appraisal to guide interventions and appropriate treatment selection. However, the association of age with GA-identified impairments (GA impairments) remains understudied and the appropriate age cutoff for using the GA remains unknown. PATIENTS AND METHODS: We designed a cross-sectional study using the Cancer and Aging Resilience Evaluation (CARE) registry of older adults with cancer. We included adults aged ≥60 years diagnosed with gastrointestinal malignancy who underwent a patient-reported GA prior to their initial consultation at the gastrointestinal oncology clinic. We noted the presence of GA impairments and frailty using Rockwood's deficit accumulation approach. We studied the relation between chronologic age and GA impairments/frailty using Spearman rank correlation and chi-square tests of trend. RESULTS: We identified 455 eligible older adults aged ≥60 years with gastrointestinal malignancies; the median age was 68 years (range, 64-74 years) and colorectal (33%) and pancreatic (24%) cancers were the most common cancer type. The correlation between chronologic age and number of geriatric impairments was weak and did not reach statistical significance (Spearman ρ, 0.07; P=.16). Furthermore, the prevalence of domain-specific impairments or frailty was comparable across the 3 age groups (60-64 years, 65-74 years, ≥75 years) with the exception of comorbidity burden. Notably, 61% of patients aged 60 to 64 years had ≥2 GA impairments and 35% had evidence of frailty, which was comparable to patients aged 65 to 74 years (66% and 36%, respectively) and ≥75 years (70% and 40%, respectively). CONCLUSIONS: Using chronologic age alone to identify which patients may benefit from GA is problematic. Future studies should identify screening tools that may identify patients at high risk of frailty and GA impairments.

BACKGROUND: There is a long history of segregation in the U.S.A with enduring impacts on cancer outcomes today. We evaluated the impact of segregation on racial disparities in Hepatocellular Carcinoma (HCC) treatment and outcomes. METHODS: We obtained data on black and white patients with HCC from the SEER program (2005-2015) within the 100 most populous participating counties. Our exposure was the index of dissimilarity (IoD), a validated measure of segregation. Outcomes were overall survival, advanced stage at diagnosis (Stage III/IV) and surgery for localized disease (Stage I/II). Cancer-specific survival was assessed using Kaplan-Meier estimates. RESULTS: Black patients had a 1.18 times increased risk (95%CI 1.14,1.22) of presenting at advanced stage as compared to white patients and these disparities disappeared at low levels of segregation. In the highest quartile of IoD, black patients had a significantly lower survival than white (17 months vs 27 months, p < 0.001), and this difference disappeared at the lowest quartile of IoD. CONCLUSIONS: Our data illustrate that structural racism in the form racial segregation has a significant impact on racial disparities in the treatment of HCC. Urban and health policy changes can potentially reduce disparities in HCC outcomes.
