Article Abstract
Background: Cholangiocarcinoma (CCA) is an increasing cause of mortality in the U.S.; however, the burden of CCA disproportionately impacts racial and ethnic minority groups. We aimed to characterize racial and ethnic differences in stage, treatment, and survival among patients with CCA.
Methods: We systematically searched MEDLINE and Embase through March 2023 for all studies reporting clinical outcomes among patients with CCA stratified by race and ethnicity. We calculated pooled hazard ratios (HRs) using the DerSimonian and Laird method for a random-effects model.
Results: Of 292 articles, 16 met inclusion criteria (n=248,109 patients). Among 6 studies (n=87,938) reporting overall survival, Black patients had worse survival (pooled HR 1.05, 95%CI 1.01-1.10) whereas Hispanic (pooled HR 0.86, 95%CI 0.83-0.89) and Asian/Pacific Islander (pooled HR 0.88, 95%CI 0.85-0.90) patients had better survival than White patients. Compared to White patients, Black and Hispanic patients were less likely to present at an early stage, and Black patients were less likely to undergo resection (pooled OR 0.69 95%CI 0.63-0.75). The limitations of studies were lack of granularity on subtype and risk of residual confounding.
Conclusion: There are racial and ethnic differences in CCA prognosis in the US, with Black patients having worse survival and Hispanic and Asian patients having better survival than White patients. Studies are needed to identify actionable factors underlying this disparity to promote health equity and improve outcomes for patients.
Impact: There exists racial discrepancies in survival and treatment for cholangiocarcinoma; more studies are needed to better understand the extent and causes of discrepancies.

This paper will present a case study of local responses to the epidemic in immigrant enclaves and majority-black neighborhoods in Atlanta, Georgia. The COVID-19 health crisis presents an unprecedented challenge for many black and brown communities in the United States which may be particularly vulnerable to the contagion because of higher rates of certain pre-existing conditions like heart disease, lack of access to adequate healthcare services, and financial pressures to continue working despite increasingly risky conditions. In the American South where burgeoning ethnic enclaves, well-establish majority-black neighborhoods, and affluent suburbs exist side by side with vastly different healthcare concerns, disorganized governmental responses to the COVID-19 epidemic highlight the importance of efforts by CBOs (i.

The 2019 novel coronavirus disease (COVID-19) has brought to the forefront racial disparities in health outcomes across the US, but there is limited formal analysis into factors associated with these disparities. In-depth examination of COVID-19 disparities has been challenging due to inconsistent case definition, isolation procedures, and incomplete racial and medical information. As of June 2020, over 14,000 (25%) confirmed COVID-19 cases in Georgia did not have racial information.

The Oncotype DX test is standardly used for patients with early-stage, hormone-receptor-positive, HER2-negative breast cancers to determine the benefit from chemotherapy and the likelihood of distant recurrence. The relationship between Oncotype DX recurrence scores and race/ethnicity is still being studied. This retrospective study aims to evaluate the relationship between Oncotype DX recurrence scores, race/ethnicity, and clinicopathological factors and to support the applicability of the Oncotype DX test for a diverse breast cancer population of Hawaii.
