Gupta A, Roy AM. Racial and Ethnic Disparities in Survival Outcomes of Metastatic Renal Cell Carcinoma Patients Receiving Immunotherapy. Clin Genitourin Cancer 2024; 22:102104. [PMID: 38834500 DOI: 10.1016/j.clgc.2024.102104] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2024] [Revised: 04/21/2024] [Accepted: 04/22/2024] [Indexed: 06/06/2024]
Abstract
BACKGROUND Immune checkpoint inhibitors (ICI) have significantly improved survival outcomes of metastatic renal cell carcinoma (mRCC). However, ethnic and racial minorities are often underrepresented in ICI clinical trials, leading to limited knowledge about ICI-specific survival outcomes for mRCC across different racial and ethnic groups. We investigated the impact of race and ethnicity on the ICI-specific survival outcomes of mRCC. MATERIALS We used The National Cancer Database (NCDB) to retrieve the data of 4858 mRCC patients diagnosed from 2014 to 2019 and receiving ICI-based regimens. We then compared survival outcomes using the Kaplan-Meier method and the Log-rank test. We analyzed the data using univariate and multivariable Cox regression analysis, adjusted for age, sex, comorbidity index, treatment centers, and grade. RESULTS White and Asian patients had significantly longer median overall survival (mOS) than African American (AA) patients (23.2 [95% CI 21.6, 24.7; P = .001] and 22.2 [95% CI 16.4, 55.1; P = .047] vs. 14.8 [95% CI 11.9, 19.2] months, respectively). After adjustment, White patients had significantly longer median OS (adjusted hazard ratio [HR] 0.71 [95% CI 0.58, 0.84]; P = .001). There was no significant difference in the mOS between Hispanic and non-Hispanic patients (P = .39). CONCLUSION Black race is an independent predictor of ICI-related survival in mRCC patients, independent of sociodemographics, clinicopathological, and treatment-related factors. Future research is required to understand the underlying reasons for these disparities, including potential genetic or biological differences and social and environmental factors.

Kopelman ZA, Baker TM, Aden JK, Ramirez CI. Postoperative Venous Thromboembolism Following Hysterectomy in the Department of Defense. Mil Med 2024; 189:1106-1113. [PMID: 36892149 DOI: 10.1093/milmed/usad064] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2022] [Revised: 11/04/2022] [Accepted: 02/23/2023] [Indexed: 03/10/2023] Open
Abstract
INTRODUCTION Hysterectomy is the most common major gynecologic procedure performed in the USA. Surgical complications, such as venous thromboembolism (VTE), are known risks that can be mitigated by preoperative risk stratification and perioperative prophylaxis. Based on recent data, the current post-hysterectomy VTE rate is found to be 0.5%. Postoperative VTE significantly impacts health care costs and patients' quality of life. Additionally, for active duty personnel, it can negatively impact military readiness. We hypothesize that the incidence of post-hysterectomy VTE rates will be lower within the military beneficiary population because of the benefits of universal health care coverage. MATERIALS AND METHODS The Military Health System (MHS) Data Repository and Management Analysis and Reporting Tool was used to conduct a retrospective cohort study of postoperative VTE rates within 60 days of surgery among women who underwent a hysterectomy at a military treatment facility between October 1, 2013, and July 7, 2020. Patient demographics, Caprini risk assessment, preoperative VTE prophylaxis, and surgical details were obtained by chart review. Statistical analysis was performed using the chi-squared test and Student t-test. RESULTS Among the 23,391 women who underwent a hysterectomy at a military treatment facility from October 2013 to July 2020, 79 (0.34%) women were diagnosed with VTE within 60 days of their surgery. This post-hysterectomy VTE incidence rate (0.34%) is significantly lower than the current national rate (0.5%, P < .0015). There were no significant differences in postoperative VTE rates with regard to race/ethnicity, active duty status, branch of service, or military rank. Most women with post-hysterectomy VTE had a moderate-to-high (4.29 ± 1.5) preoperative Caprini risk score; however, only 25% received preoperative VTE chemoprophylaxis. CONCLUSION MHS beneficiaries (active duty personnel, dependents, and retirees) have full medical coverage with little to no personal financial burden for their health care. We hypothesized a lower VTE rate in the Department of Defense because of universal access to care and a presumed younger and healthier population. The postoperative VTE incidence was significantly lower in the military beneficiary population (0.34%) compared to the reported national incidence (0.5%). Additionally, despite all VTE cases having moderate-to-high preoperative Caprini risk scores, the majority (75%) received only sequential compression devices for preoperative VTE prophylaxis. Although post-hysterectomy VTE rates are low within the Department of Defense, additional prospective studies are needed to determine if stricter adherence to preoperative chemoprophylaxis can further reduce post-hysterectomy VTE rates within the MHS.

Differences in Survival between Black and White Patients with Head and Neck Squamous Cell Carcinoma: Comparison of Data from the DOD Central Cancer Registry and SEER. Cancer Epidemiol Biomarkers Prev 2024; 33:426-434. [PMID: 38099827 DOI: 10.1158/1055-9965.epi-23-0862] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2023] [Revised: 11/06/2023] [Accepted: 12/13/2023] [Indexed: 03/02/2024] Open
Abstract
BACKGROUND Barriers to health care access may contribute to the poorer survival of Black patients with head and neck squamous cell carcinoma (HNSCC) than their White counterparts in the U.S. general population. The Department of Defense's (DOD) Military Health System (MHS) provides universal health care access to all beneficiaries with various racial backgrounds. METHODS We compared overall survival of patients with HNSCC by race in the MHS and the general population, respectively, to assess whether there were differences in racial disparity between the two populations. The MHS patients were identified from the DOD's Central Cancer Registry (CCR) and the patients from the U.S. general population were identified from the NCI's Surveillance, Epidemiology and End Results (SEER) program. For each cohort, a retrospective study was conducted comparing survival by race. RESULTS Black and White patients in the CCR cohort had similar survival in multivariable Cox regression models with a HR of 1.04 and 95% confidence interval (95% CI) of 0.81 to 1.33 after adjustment for the potential confounders. In contrast, Black patients in the SEER cohort exhibited significantly worse survival than White patients with an adjusted HR of 1.47 (95% CI = 1.43-1.51). These results remained similar in the subgroup analyses for oropharyngeal and non-oropharyngeal sites, respectively. CONCLUSIONS There was no racial difference in survival among patients with HNSCC in the MHS system, while Black patients had significantly poorer survival than White patients in the general population. IMPACT Equal access to health care could reduce racial disparity in overall survival among patients with HNSCC.

Abstract
INTRODUCTION Disparities in prostate, bladder, and kidney cancer outcomes are associated with access to care. Telemedicine can improve access but may be underutilized by certain patient populations. Our objective was to determine if the patient populations who suffer worse oncologic outcomes are the same as those who are less likely to use telemedicine. METHODS Using an institutional database, we identified all prostate, bladder and kidney cancer encounters from March 14, 2020 to October 31, 2021 (n = 15,623; n = 4, 14; n = 3,830). Telemedicine was used in 13%, 8%, and 12% of these encounters, respectively. We performed random effects modeling analysis to examine patient and provider characteristics associated with telemedicine use. Adjusted odds ratios (OR) and 95% confidence intervals (CI) were reported as measures of association. RESULTS Among prostate, bladder, and kidney cancer patients, Black patients had lower odds of a telemedicine encounter (OR 0.51, 95% CI 0.37-0.69; OR 0.22, 95% CI 0.07-0.70; OR 0.46, 95% CI 0.24-0.86), and patients residing in small and isolated small rural towns areas had higher odds of a telemedicine encounter (OR 1.44, 95% CI 1.09-1.91; OR 2.12, 95% CI 1.14-3.94; OR 1.89, 95% CI 1.12-3.19). Compared to providers in practice ≤5 years, providers in practice for 6 to 15 years had significantly higher odds of a telemedicine encounter for prostate and bladder cancer patients (OR 4.10, 95% CI 1.4511.58; OR 3.42, 95% CI 1.09-10.77). CONCLUSION The lower rates of telemedicine use among Black patients could exacerbate pre-existing disparities in prostate, bladder, and kidney cancer outcomes.

Abstract
The Military Health System (MHS) of the US Department of Defense (DoD) provides comprehensive medical care to over nine million beneficiaries, including active-duty members, reservists, activated National Guard, military retirees, and their family members. The MHS generates an extensive database containing administrative claims and medical encounter data, while the DoD also maintains a cancer registry that collects information about the occurrence of cancer among its beneficiaries who receive care at military treatment facilities. Collating data from the two sources diminishes the limitations of using registry or medical claims data alone for cancer research and extends their usage. To facilitate cancer research using the unique military health resources, a computer interface linking the two databases has been developed, called Military Cancer Epidemiology, or MilCanEpi. The intent of this article is to provide an overview of the MilCanEpi data system, describing its components, structure, potential uses, and limitations.

Abstract
Epidemiological studies reveal disparities in cancer incidence and outcome rates between racial groups in the United States. In our study, we investigated molecular differences between racial groups in 10 carcinoma types. We used publicly available data from The Cancer Genome Atlas to identify patterns of differential gene expression in tumor samples obtained from 4112 White, Black/African American, and Asian patients. We identified race-dependent expression of numerous genes whose mRNA transcript levels were significantly correlated with patients' survival. Only a small subset of these genes was differentially expressed in multiple carcinomas, including genes involved in cell cycle progression such as CCNB1, CCNE1, CCNE2, and FOXM1. In contrast, most other genes, such as transcriptional factor ETS1 and apoptotic gene BAK1, were differentially expressed and clinically significant only in specific cancer types. Our analyses also revealed race-dependent, cancer-specific regulation of biological pathways. Importantly, homology-directed repair and ERBB4-mediated nuclear signaling were both upregulated in Black samples compared to White samples in four carcinoma types. This large-scale pan-cancer study refines our understanding of the cancer health disparity and can help inform the use of novel biomarkers in clinical settings and the future development of precision therapies.

Abstract
Disparities in metastatic renal cell carcinoma (mRCC) outcomes persist in the era of oral anticancer agents (OAAs) and immunotherapies (IOs). We examined variation in the utilization of mRCC systemic therapies among US Medicare beneficiaries from 2015 to 2019. Logistic regression models evaluated the association between therapy receipt and demographic covariates including patient race, ethnicity, and sex. In total, 15 407 patients met study criteria. After multivariable adjustment, non-Hispanic Black race and ethnicity was associated with reduced IO (adjusted relative risk ratio [aRRR] = 0.76, 95% confidence interval [CI] = 0.61 to 0.95; P = .015) and OAA receipt (aRRR = 0.76, 95% CI = 0.64 to 0.90; P = .002) compared with non-Hispanic White race and ethnicity. Female sex was associated with reduced IO (aRRR = 0.73, 95% CI = 0.66 to 0.81; P < .001) and OAA receipt (aRRR = 0.74, 95% CI = 0.68 to 0.81; P < .001) compared with male sex. Thus, disparities by race, ethnicity, and sex were observed in mRCC systemic therapy utilization for Medicare beneficiaries from 2015 to 2019.

Abstract
BACKGROUND Cancers of unknown primary (CUP), a group of heterogenous metastatic cancers lacking a known primary site, have poor prognosis. This study compared survival of CUP by histologic type, patient characteristics, and treatment in the U.S. Military Health System (MHS), which provides universal care to its members. METHODS Patients histologically diagnosed with CUP were identified from the U.S. Department of Defense (DoD)'s Automated Central Tumor Registry. Median survival with 95 % confidence intervals was calculated for demographic and treatment variables by histologic type. A multivariable accelerated failure time model estimated time ratios and 95 % confidence intervals. RESULTS The study included 3358 CUP patients. The most prevalent CUP in this study was well- and moderately-differentiated adenocarcinomas. Median survival varied by histologic type with squamous cell carcinoma having the longest at 25.1 months and poorly-differentiated carcinomas having the shortest at 3.0 months. For each histologic type, survival was generally similar by sex and active-duty status although women with well- and moderately-differentiated adenocarcinoma had longer survival than their male counterparts. Younger patients tended to have longer survival than those aged 65 years or older. Generally, there were no racial differences in survival except poorer survival for Black patients than White patients in the group of other histologic types. Patients with chemotherapy and radiation treatment generally had improved survival whereas patients with squamous cell carcinoma who received chemotherapy had shorter survival than those without. CONCLUSION Survival generally did not differ between racial groups, which may be related to equal healthcare access despite racial background. Further studies are warranted to better understand how survival in the MHS compares with that in the general U.S. POPULATION

Abstract
OBJECTIVE To examine real-world adherence to oral anticancer agents (OAAs) and its association with outcomes among Medicare beneficiaries with metastatic renal cell carcinoma (mRCC). METHODS SEER-Medicare retrospective cohort study of patients with metastatic renal cell carcinoma (mRCC) who received an OAA between 2007 and 2015. We examined A) adherence and B) overall and disease-specific 2-year survival landmarked at 3 months after OAA initiation. Adherence was assessed by calculating the proportion of days covered (PDC) within 3 months of OAA initiation, with adherent use being defined as PDC > 80%. RESULTS A total of 905 patients met study criteria, of whom 445 patients (49.2%) were categorized as adherent to initial OAA treatment. Adjusting for clinical and demographic factors revealed decreased odds of adherence associated with living within an impoverished neighborhood (OR 0.49, CI 0.0.33 - 0.74) and out-of-pocket costs > $200 (OR 0.68, CI 0.47-.98). Adherence was associated with improved 2-year survival in univariate analysis (logrank test, P = .01) and a non-significant trend toward an association with decreased all-cause (HR 0.87, CI 0.72 - 1.05) and RCC-specific survival (HR 0.84, CI 0.69 - 1.03) in multivariable analysis. CONCLUSION Local poverty levels and high out-of-pocket costs are associated with poor initial adherence to OAA therapy in Medicare beneficiaries with mRCC, which in turn, suggests a trend toward poor overall and disease-specific survival. Efforts to improve outcomes in the broader mRCC population should incorporate OAA adherence and economic factors.

Patient, provider, and hospital factors associated with oral anti-neoplastic agent initiation and adherence in older patients with metastatic renal cell carcinoma. J Geriatr Oncol 2022; 13:614-623. [PMID: 35125336 PMCID: PMC9232903 DOI: 10.1016/j.jgo.2022.01.008] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2021] [Revised: 12/16/2021] [Accepted: 01/13/2022] [Indexed: 12/27/2022]
Abstract
INTRODUCTION Oral anti-neoplastic agents (OAAs) for metastatic renal cell carcinoma (mRCC) are associated with increased cancer-specific survival. However, racial disparities in survival persist and older adults have the lowest rates of cancer-specific survival. Research from other cancers demonstrates specialty access is associated with high-quality cancer care, but older adults receive cancer treatment less often than younger adults. We therefore examined whether patient, provider, and hospital characteristics were associated with OAA initiation, adherence, and cancer-specific survival after initiation and whether race, ethnicity, and/or age was associated with an increased likelihood of seeing a medical oncologist for diagnosis of mRCC. PATIENTS AND METHODS We used Surveillance, Epidemiology, and End Results (SEER)Medicare data to identify patients ≥65 years of age who were diagnosed with mRCC from 2007 to 2015 and enrolled in Medicare Part D. Insurance claims were used to identify receipt of OAAs within twelve months of metastatic diagnosis, calculate proportion of days covered, and to identify the primary cancer provider and hospital. We examined provider and hospital characteristics associated with OAA initiation, adherence, and all-cause mortality after OAA initiation. RESULTS We identified 2792 patients who met inclusion criteria. Increased OAA initiation was associated with access to a medical oncologist. Patients were less likely to begin OAA treatment if their primary oncologic provider was a urologist (hazard ratio [HR] 0.62; 95% confidence interval [CI] 0.49-0.77). Provider/hospital characteristics were not associated with differences in OAA adherence or mortality. Patients who started sorafenib (odds ratio [OR] 0.50; 95% CI 0.29-0.86), were older (aged >81 OR 0.56; 95% CI 0.34-0.92), and those living in high poverty ZIP codes (OR 0.48; 95% CI 0.29-0.80) were less likely to adhere to OAA treatment. Furthermore, provider characteristics did not account for differences in mortality once an OAA was initiated. Last, only age > 81 years was statistically and clinically associated with a decreased relative risk of seeing a medical oncologist (risk ratio [RR] 0.87; CI 0.82-0.92). CONCLUSION Provider/hospital factors, specifically, being seen by a medical oncologist for mRCC diagnosis, are associated with OAA initiation. Older patients were less likely to see a medical oncologist; however, race and/or ethnicity was not associated with differences in seeing a medical oncologist. Patient factors are more critical to OAA adherence and mortality after OAA initiation than provider/hospital factors.

Abstract
Background Clear-cell renal cell carcinoma (ccRCC) is one of the most common malignant
tumors worldwide whose poor prognosis results in a serious disease burden on
patients. The changing trend of the long-term relative survival rates (RSRs)
of patients with ccRCC was analyzed in this study to evaluate their
treatment results over a 15-year period. Methods This study is a retrospective study, which assessed and predicted the 1-, 3-,
and 5-year survival rates of patients with ccRCC during 2001-2005,
2006-2010, 2011-2015, and 2016-2020 using data extracted from the
Surveillance, Epidemiology, and End Results (SEER) database. Period analysis
was used in this study to analyze the data from the SEER database and to
assess survival differences according to age, sex, race, and socioeconomic
status (SES) during the 15-year study period by comparing Kaplan-Meier
curves. Results During 2001-2015, the 5-year RSR of patients with ccRCC increased from 78.4%
to 83.0%, and the generalized linear model predicted that the 5-year RSR
increased to 85.7% during 2016-2020. The RSR of patients with ccRCC differed
significantly with SES, race, sex, and age. Compared with male patients, the
survival advantage of female patients decreased as their age increased. The
RSR of all patients with ccRCC was also lower in patients with a lower SES
and of black race. Conclusion This study found an improvement in the RSR of patients with ccRCC during
2001-2020. Understanding the change trend of the survival rate of patients
with ccRCC is helpful to improve the design of clinical trials. It also
provides basic data and a scientific basis for evaluating the harm of ccRCC
on the health of affected patients and the effect of cancer prevention, and
developing cancer prevention plans.

Abstract
OBJECTIVES To evaluate racial, gender, and socioeconomic differences in the treatment of metastatic renal cell carcinoma (mRCC) and their impact on survival. METHODS Patients aged ≥18 years diagnosed with mRCC in the National Cancer Database (2004-2015) were analyzed. Multivariable logistic regression models were used to evaluate factors associated with systemic therapy and CN utilization. Cox proportional hazards regression models were used to evaluate overall survival. RESULTS In total, 31,989 patients with mRCC were identified with 30.2% receiving CN, 51.6% receiving systemic therapy, and 25.8% receiving no treatment. Females were at lower odds of receiving systemic therapy (OR 0.91, p<0.01) and increased odds of no treatment (OR 1.14, p<0.01). Non-Hispanic Black and Hispanic patients were at decreased odds of receiving CN (OR 0.75, p<0.01 and OR 0.86, p=0.01, respectively). Black patients were at decreased odds of receiving systemic therapy (OR 0.85, p<0.01) and increased odds of no treatment (OR 1.41, p<0.01). Adjusting for demographic and disease variables, Black patients were at increased risk of death (HR 1.06, p=0.03), largely due to less use of systemic therapy and CN; survival differences disappeared after accounting for receipt of therapy (HR 0.99, p=0.66). CONCLUSIONS There are racial, gender, and socioeconomic differences in the treatment of mRCC which are associated with a disparity in overall survival. Dismantling systemic barriers and improving access to care may lead to reduced disparities and improved outcomes for mRCC.

Abstract
BACKGROUND We sought to compare survival outcomes of sarcomas in the pediatric and adolescent/young adult populations with universal care access in the Military Health System (MHS) to those from the United States general population. METHODS We compared data from the Department of Defense's (DoD) Automated Central Tumor Registry (ACTUR) and the National Cancer Institute's (NCI) Surveillance, Epidemiology, and End Results (SEER) program on the overall survival of patients 24 years or younger with histologically or microscopically confirmed sarcoma between diagnosed between January 1, 1987, and December 31, 2013. The Kaplan-Meier survival curves were used to compare survival between the 2 patient populations. Cox proportional hazard models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) comparing ACTUR relative to SEER. RESULTS The final analysis included 309 and 1236 bone sarcoma cases and 465 and 1860 soft tissue sarcoma cases from ACTUR and SEER, respectively. Cox proportional hazards analysis showed soft tissue sarcoma patients in ACTUR had significantly better overall (HR=0.73, 95% CI=0.55-0.98) and 5-year overall (HR=0.63, 95% CI=0.46-0.86) survival compared with SEER patients, but no significant difference in overall or 5-year overall survival between ACTUR and SEER patients with bone sarcoma. CONCLUSION Survival data from the ACTUR database demonstrated significantly improved overall survival for soft tissue sarcomas and equivalent survival in bone sarcomas compared with that reported by SEER.

Abstract
Background and Objectives: The National Cancer Database (NCDB) captures nearly 70% of all new cancer diagnoses in the United States, but there exists significant variation in this capture rate based on primary tumor location and other patient demographic factors. Prostate cancer has the lowest coverage rate of all major cancers, and other genitourinary malignancies likewise fall below the average NCDB case coverage rate. We aimed to explore NCDB coverage rates for patients with genitourinary cancers as a function of race. Materials and Methods: We compared the incidence of cancer cases in the NCDB with contemporary United States Cancer Statistics data. Results: Across all malignancies, American Indian/Alaskan Natives subjects demonstrated the lowest capture rates, and Asian/Pacific Islander subjects exhibited the second-lowest capture rates. Between White and Black subjects, capture rates were significantly higher for White subjects overall and for prostate cancer and kidney cancer in White males, but significantly higher for bladder cancer in Black versus White females. No significant differences were observed in coverage rates for kidney cancer in females, bladder cancer in males, penile cancer, or testicular cancer in White versus Black patients. Conclusions: Differential access to Commission on Cancer-accredited treatment facilities for racial minorities with genitourinary cancer constitutes a unique avenue for health equity research.

Renal Cell Carcinoma Health Disparities in Stage and Mortality among American Indians/Alaska Natives and Hispanic Americans: Comparison of National Cancer Database and Arizona Cancer Registry Data. Cancers (Basel) 2021; 13:cancers13050990.

Abstract
Simple Summary This study assessed renal cell carcinoma disparities in American Indians/Alaska Natives and Hispanic Americans using the National Cancer Database and the Arizona Cancer Registry, focusing on advanced-stage and mortality. Renal cell carcinoma disparities in American Indians/Alaska Natives have been partially explained by neighborhood socioeconomic factors and residence (rural or urban) pattern, but not in Hispanic Americans. Greater health disparities in renal cell carcinoma stage and mortality for Hispanic Americans and renal cell carcinoma mortality for American Indians/Alaska Natives were observed at the Arizona state level compared to national levels. Abstract Renal cell carcinoma (RCC) is one of the top 10 cancers in the United States. This study assessed RCC health disparities in American Indians/Alaska Natives (AIs/ANs) and Hispanic Americans (HAs) focusing on advanced-stage and mortality. RCC patients’ data were obtained from the National Cancer Database (NCDB) and Arizona Cancer Registry (ACR). Logistic and Cox regression analyses were performed to ascertain the effect of race/ethnicity on stage and mortality, adjusting for neighborhood socioeconomic factors, rural/urban residence pattern, and other factors. In both data sets, AIs/ANs had significantly increased odds of advanced-stage RCC in the unadjusted model, but not in adjusted models. Mexican Americans had higher odds of advanced-stage compared to non-Hispanic Whites in NCDB (OR 1.22, 95% CI: 1.11–1.35) and ACR (OR 2.02, 95% CI: 1.58–2.58), even after adjusting for neighborhood characteristics. AIs/ANs did not show increased mortality risk in NCDB after adjusting for neighborhood characteristics, while the association remained significant in ACR (HR 1.33, 95% CI: 1.03–1.72). The great risk of all-cause and RCC-specific mortality was observed in U.S.-born Mexican Americans in Arizona (HR 3.21, 95% CI: 2.61–3.98 and sub-distribution HR 2.79, 95% CI: 2.05–3.81). RCC disparities in AIs/ANs is partially explained by neighborhood factors, but not in HAs.

Abstract
BACKGROUND: No study to date has assessed the relationship between treatment-specific therapeutic outcomes and race/ethnicity in metastatic renal cell carcinoma (mRCC). As targeted therapies have formed the backbone of first-line treatment options for mRCC until very recently, we assessed the relationship between race/ethnicity and targeted therapy-related outcomes in mRCC. OBJECTIVE: To retrospectively compare response rates and survival outcomes across ethnicities in patients who received first-line targeted therapies for mRCC. METHODS: Patients with mRCC receiving a first-line targeted therapy were identified from an institutional database encompassing consecutive patients treated between 2009 and 2019. Patient demographics, clinical characteristics and survival outcomes were recorded. The racial/ethnic groups included for analysis were Caucasian American, Hispanic American, and Asian American. Survival and response outcomes including progression-free survival (PFS), overall survival (OS), objective response rate (ORR) and disease control rate (DCR) were calculated and compared across ethnic groups using Kaplan-Meier method and Chi-square test, respectively. RESULTS: In total, 295 patients were included for analysis. There were 184 (62.4%) Caucasian American patients, 82 (27.8%) Hispanic American patients, and 29 (9.8%) Asian American patients. No statistically significant differences in PFS nor OS were found between groups (PFS: 5.6 vs. 4.7 vs. 4.7 months, respectively) (OS: 32 vs. 31.7 vs. 51.7 months, respectively). No significant difference was found in ORR nor DCR across groups. Univariate cox regression analyses demonstrated no independent effect of race/ethnicity on PFS or OS. CONCLUSIONS: The apparent lack of differences in treatment-related outcomes across racial/ethnic groups is encouraging. However, further validation is required in larger series.

Abstract
Background Racial/ethnic minority groups have a higher burden of renal cell carcinoma (RCC), but RCC among Hispanic Americans (HAs) and American Indians and Alaska Natives (AIs/ANs) are clinically not well characterized. We explored variations in age at diagnosis and frequencies of RCC histologic subtypes across racial/ethnic groups and Hispanic subgroups using National Cancer Database (NCDB) and Arizona Cancer Registry Data. Methods Adult RCC cases with known race/ethnicity were included. Logistic regression analysis was performed to estimate odds and 95% confidence interval (CI) of early‐onset (age at diagnosis <50 years) and diagnosis with clear cell RCC (ccRCC) or papillary RCC. Results A total of 405 073 RCC cases from NCDB and 9751 cases from ACR were identified and included. In both datasets, patients from racial/ethnic minority groups had a younger age at diagnosis than non‐Hispanic White (NHW) patients. In the NCDB, AIs/ANs had twofold increased odds (OR, 2.21; 95% CI, 1.88‐2.59) of early‐onset RCC compared with NHWs. HAs also had twofold increased odds of early‐onset RCC (OR, 2.14; 95% CI, 1.79‐2.55) in the ACR. In NCDB, ccRCC was more prevalent in AIs (86.3%) and Mexican Americans (83.5%) than NHWs (72.5%). AIs/ANs had twofold increased odds of diagnosis with ccRCC (OR, 2.18; 95% CI, 1.85‐2.58) in the NCDB, but the association was stronger in the ACR (OR, 2.83; 95% CI, 2.08‐3.85). Similarly, Mexican Americans had significantly increased odds of diagnosis with ccRCC (OR, 2.00; 95% CI, 1.78‐2.23) in the NCDB. Conclusions This study reports younger age at diagnosis and higher frequencies of ccRCC histologic subtype in AIs/ANs and Hispanic subgroups. These variations across racial/ethnic groups and Hispanic subgroups may have potential clinical implications.

Abstract
Kidney cancer ranks among the top 10 cancers in the United States. Although it affects both male and female populations, it is more common in males. The prevalence rate of renal cell carcinoma (RCC), which represents about 85% of kidney cancers, has been increasing gradually in many developed countries. Family history has been considered as one of the most relevant risk factors for kidney cancer, although most forms of an inherited predisposition for RCC only account for less than four percent. Lifestyle and other factors such as occupational exposure, high blood pressure, poor diet, and heavy cigarette smoking are highly associated with its incidence and mortality rates. In the United States, White populations have the lowest prevalence of RCC compared to other ethnic groups, while Black Americans suffer disproportionally from the adverse effects of RCC. Hence, this review article aims at identifying the major risk factors associated with RCC and highlighting the new therapeutic approaches for its control/prevention. To achieve this specific aim, articles in peer-reviewed journals with a primary focus on risk factors related to kidney cancer and on strategies to reduce RCC were identified. The review was systematically conducted by searching the databases of MEDLINE, PUBMED Central, and Google Scholar libraries for original articles. From the search, we found that the incidence and mortality rates of RCC are strongly associated with four main risk factors, including family history (genetics), lifestyle (poor diet, cigarette smoking, excess alcohol drinking), environment (community where people live), and occupation (place where people work). In addition, unequal access to improvement in RCC cancer treatment, limited access to screening and diagnosis, and limited access to kidney transplant significantly contribute to the difference observed in survival rate between African Americans and Caucasians. There is also scientific evidence suggesting that some physicians contribute to racial disparities when performing kidney transplant among minority populations. New therapeutic measures should be taken to prevent or reduce RCC, especially among African Americans, the most vulnerable population group.

Abstract
Background Advanced renal cell carcinoma (RCC) results in over 14,000 deaths each year in the United States alone. The therapeutic landscape for advanced RCC changed dramatically with the approval of tyrosine kinase inhibitors (TKI) between 2006 and 2012. A large-scale analysis of survival trends has not been performed in the TKI era to determine their impact on outcomes for advanced RCC patients. Methods The Surveillance, Epidemiology and End-Results (SEER) database was queried for adult patients with advanced RCC diagnosed between 2000 and 2013. Patients were divided into two cohorts based on the year of diagnosis-pre-TKI cohort [2000-2006] and TKI cohort [2007-2013]. Kaplan-Meier survival and multivariate Cox proportional hazards analyses were performed. Results A total of 14,976 patients were included in our study. Median age at diagnosis was 64 years (range, 18-89 years). Median (cancer-specific) overall survival was 10.0 months in the TKI cohort compared with 8.0 months in the pre-TKI cohort, corresponding to a 13% improvement in survival in the TKI area [hazard ratio (HR) for death 0.87; 95% confidence interval (CI), 0.84-0.91, P<0.0001]. Median survival was improved by 2 months for patients with clear-cell RCC histology [HR for death 0.86; 95% CI, 0.84-0.91, P<0.0001]. Patients with non-clear cell RCC had a 25% higher risk of mortality compared with those with clear-cell RCC. Additionally, median survival for non-clear cell RCC patients was not statistically different between the two cohorts (HR for death 0.98; 95% CI, 0.88-1.09, P=0.714). Subgroup analysis showed that elderly patients (age 71 years and above) had a 45% higher risk of death from advanced RCC compared with young patients (aged 18-50 years) [HR for death 1.45; 95% CI, 1.36-1.54, P<0.0001]. Gender and racial disparities in outcomes were also noted with women having a 10% higher risk of death compared with men (HR for death 1.10; 95% CI, 1.06-1.14, P<0.001) and Black patients having a 15% higher risk of death compared with White patients (HR for death 1.15; 95% CI, 1.08-1.23, P<0.0001). Conclusions Our study provides a largest registry-based analysis of survival outcomes in the TKI era. In majority of patients, the survival has improved significantly with the advent of TKIs as standard of care therapy. Survival for patients with non-clear cell RCC is clearly worse than clear-cell RCC and does not appear to have changed with TKIs. Elderly patients, women, and Black patients appear to have worse outcomes and these disparities merit further investigation.

Abstract
Background: The U.S. military health system (MHS) provides universal health care access to its beneficiaries. However, whether the universal access has translated into improved patient outcome is unknown. This study compared survival of non-small cell lung cancer (NSCLC) patients in the MHS with that in the U.S. general population.Methods: The MHS data were obtained from The Department of Defense's (DoD) Automated Central Tumor Registry (ACTUR), and the U.S. population data were drawn from the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) program. The study subjects were NSCLC patients diagnosed between January 1, 1987, and December 31, 2012, in ACTUR and a sample of SEER patients who were matched to the ACTUR patients on age group, sex, race, and year of diagnosis group with a matching ratio of 1:4. Patients were followed through December 31, 2013.Results: A total of 16,257 NSCLC patients were identified from ACTUR and 65,028 matched patients from SEER. Compared with SEER patients, ACTUR patients had significantly better overall survival (log-rank P < 0.001). The better overall survival among the ACTUR patients remained after adjustment for potential confounders (HR = 0.78, 95% confidence interval, 0.76-0.81). The survival advantage of the ACTUR patients was present regardless of cancer stage, grade, age group, sex, or race.Conclusions: The MHS's universal care and lung cancer care programs may have translated into improved survival among NSCLC patients.Impact: This study supports improved survival outcome among NSCLC patients with universal care access.

Abstract
OBJECTIVE To investigate differences between Hispanics and non-Hispanic whites diagnosed with and treated for renal cell carcinoma in an equal access healthcare system. METHODS We carried out a retrospective cohort study within the Kaiser Permanente healthcare system using records from renal cell carcinoma cases. Ethnicity was identified as Hispanic or non-Hispanic whites. Patient characteristics, comorbidities, tumor characteristics and treatment were compared. Overall and disease-specific survival was calculated, and a Cox proportion hazard model estimated the association of ethnicity and survival. RESULTS A total of 2577 patients (2152 non-Hispanic whites, 425 Hispanic) were evaluated. Hispanics were diagnosed at a younger age (59.6 years vs 65.3 years). Clear cell renal cell carcinoma was more prevalent, whereas papillary renal cell carcinoma was less common among Hispanics. Hispanics had a lower American Joint Committee on Cancer stage (I/II vs III/IV) than non-Hispanic whites (67.4% vs 62.2%). Hispanics were found to have a greater frequency of comorbidities, such as chronic kidney disease and diabetes, but were more likely to receive surgery. The presence of metastases, nodal involvement, increased tumor size, non-surgical management, increasing age and Hispanic ethnicity were independent predictors of worse cancer-specific outcome. CONCLUSIONS Within an equal access healthcare system, Hispanics seem to be diagnosed at younger ages, to have greater comorbidities and to present more frequently with clear cell renal cell carcinoma compared with non-Hispanic white patients. Despite lower stage and greater receipt of surgery, Hispanic ethnicity seems to be an independent predictor of mortality. Further work is necessary to confirm these findings.

Abstract
Significant disparities in survival, incidence and possibly response to current therapies exist between black and white patients with renal cell carcinoma (RCC). Recent genomic evidence to account for these disparities has been reported for clear cell RCC. However, racial disparities at the genomic level for papillary RCC (pRCC) which is a genetically distinct and less responsive histologic subtype of RCC have not been reported. Using The Cancer Genome Atlas (TCGA) data, the present study assessed gene-level expression, somatic mutation and pathway differences between 58 black and 58 white patients with pRCC propensity matched on age, gender and pathologic T stage. Distinct tumor biology with differential expression patterns were observed in black vs. white patients with pRCC. Specifically, significance analysis of microarrays was applied to TCGA gene expression data and identified 163 genes and 120 genes overexpressed in black and white patients, respectively (FDR q<0.05). Gene Set Enrichment Analysis identified 62 gene sets enriched (p<0.10) in blacks. Enrichment of immune immune system pathways were noted in black patients. These included the B cell receptor signaling pathway, the NOD-like receptor signaling pathway and genes involved in defensins. The VEGF pathway was also more significant in black patients. CRYBB2, a gene associated with the WNT pathway was overexpressed in Black patients. While our data requires validation, these findings suggest that race may have implications for distinct immune responses to cancer and that the use of immunotherapies, and VEGFR inhibitors to target these pathways may improve survival in black patients with advanced pRCC.

Abstract
Significant racial disparities in survival for renal cell carcinoma (RCC) exist between white and black patients. Differences in access to care and comorbidities are possible contributors. To investigate if racial disparities persist when controlling for access to care, we analyzed data from a single-payer healthcare system. As part of a case-control study within the Kaiser Permanente Northern California system, pathologic and clinical records were obtained for RCC cases (2152 white, 293 black) diagnosed from 1998 to 2008. Patient demographics, comorbidities, tumor characteristics, and treatment status were compared. Overall survival and disease-specific survival (DSS) were calculated by the Kaplan-Meier method. A Cox proportion hazards model estimated the independent associations of race, comorbidity, and clinicopathologic variables with DSS. We found that compared to white patients, black patients were diagnosed at a younger age (median 62 vs. 66 years, P < 0.001), were more likely to have papillary RCC (15% vs. 5.2%, P < 0.001), and had similar rates of surgical treatment (78.8% vs. 77.9%, P = 0.764). On multivariate analysis, advanced American Joint Committee on Cancer (AJCC) stage, lack of surgical treatment, larger tumor size, and higher grade were predictors of worse DSS. Race was not an independent predictor of survival. Therefore, we conclude that within a single healthcare system, differences in characteristics of black and white patients with RCC persist; black patients had different comorbidities, were younger, and had decreased tumor stage. However, unlike other series, race was not an independent predictor of DSS, suggesting that survival differences in large registries may result from barriers to healthcare access and/or comorbidity rather than disease biology.
