Disparities in geospatial patterns of cancer care within urban counties and structural inequities in access to oncology care.
This study examined geospatial patterns of cancer care utilization across diverse populations in New Jersey-a state where most residents live in urban areas. The authors used data from the New Jersey State Cancer Registry. They examined the location of cancer treatment among patients 20-65 years of age diagnosed with breast, colorectal, or invasive cervical cancer and investigated differences in geospatial patterns of care by individual and area-level (e.g., census tract-level) characteristics. They observed significant differences in geospatial patterns of cancer treatment by race/ethnicity, insurance type, and area-level factors. They found that Black patients had a 5.6% higher likelihood of receiving care within their own residential county compared to non-Hispanic White patients. Patients living in census tracts with the highest quintile of social vulnerability were 4.6% more likely to receive treatment within their residential county and were 2.7% less likely to seek out-of-state care.

Racial disparities in the ascertainment of cancer recurrence in electronic health records.
This study examined whether the accuracy of a proxy for colorectal cancer (CRC) recurrence differed by race/ethnicity and the possible mechanisms that drove the differences. Using data from a large integrated health care system, the authors identified a stratified random sample of 282 Black/African American (AA), Hispanic, and non-Hispanic White (NHW) patients with CRC who received primary treatment. The recurrence proxy was found to have excellent overall accuracy (positive predictive value [PPV] 89.4%; negative predictive value 96.5%; mean difference in timing 1.96 months); however, accuracy varied by race/ethnicity. Compared with NHW patients, PPV was 14.9% lower among Hispanic patients and 4.3% lower among Black/AA patients. The proxy disproportionately inflated the 5-year recurrence incidence for Hispanic patients by 10.6%. Compared with NHW patients, proxy recurrences for Hispanic patients were almost three times as likely to have been misclassified as positive (adjusted risk ratio 2.91). The authors theorize that higher false positives among racial/ethnic minorities may be related to higher prevalence of noncancerous lung-related problems and substantial delays in primary treatment because of insufficient patient-provider communication and abnormal treatment patterns.

Racial and ethnic disparities in opioid access and urine drug screening among older patients with poor-prognosis cancer near the end of life.
This research characterized racial and ethnic disparities and trends in opioid access and urine drug screening (UDS) among older patients dying of cancer, and to explore potential mechanisms. Among 18,549 non-Hispanic White (White), Black, and Hispanic Medicare decedents older than 65 years with poor-prognosis cancers, the authors examined 2007-2019 trends in opioid prescription fills and potency (morphine milligram equivalents [MMEs] per day [MMEDs]) near the end of life (EOL), defined as 30 days before death or hospice enrollment. They found that between 2007 and 2019, White, Black, and Hispanic decedents experienced steady declines in EOL opioid access and rapid expansion of UDS. Compared with White patients, Black and Hispanic patients were less likely to receive any opioid (Black, -4.3 percentage points; Hispanic, -3.6 percentage points) and long-acting opioids (Black, -3.1 percentage points; Hispanic, -2.2 percentage points). They also received lower daily doses (Black, -10.5 MMED; Hispanic, -9.1 MMED) and lower total doses (Black, -210 MMEs; Hispanic, -179 MMEs). Black patients were also more likely to undergo UDS (0.5 percentage points).

Examining ACCURE's nurse navigation through an antiracist lens: transparency and accountability in cancer care.
This paper discussed an intervention that was conducted to eliminate racial disparity in cancer treatment through a program called Accountability for Cancer Care through Undoing Racism and Equity (ACCURE). The program successfully eliminated the Black-White disparity in cancer treatment completion among patients with early-stage breast and lung cancer. It used specially trained nurse navigators who leveraged real-time data to follow-up with patients during their treatment journeys. Thematic analysis on all clinical notes that were written by ACCURE navigators after each contact with patients in the specialized navigation arm (n = 162) was conducted by community and academic research partners. The authors identified six themes in the navigator notes that demonstrated enhanced accountability of the care system to patient needs. Those themes include: (1) patient-centered advocacy, (2) addressing system barriers to care, (3) connection to resources, (4) re-engaging patients after lapsed treatment, (5) addressing symptoms and side effects, and (6) emotional support.

Racial disparities in lung cancer stage of diagnosis among adults living in the southeastern United States.
The purpose of this study was to identify factors contributing to racial disparities in stage of lung cancer stage diagnosis in low-income adults. The researchers identified cases of incident lung cancer from the prospective observational Southern Community Cohort Study by linking them with state cancer registries in 12 southeastern states. A subset of participants who answered psychosocial questions such as those related to racial discrimination experiences were assessed to determine if model predictive power improved. The study identified 1,572 patients with incident lung cancer with available lung cancer stage. Compared with White participants Black participants with lung cancer reflected higher unadjusted odds of distant stage diagnosis. Higher neighborhood area deprivation was related with distant stage diagnosis. No significant differences were found in distant stage disease for Black vs White participants after controlling for individual- and area-level factors, but participants with COPD showed decreased odds of distant stage diagnosis in the primary model.

Understanding the role of urology practice organization and racial composition in prostate cancer treatment disparities.
This study examined the associations between urology practice organization and racial composition and treatment patterns for Medicare beneficiaries with incident prostate cancer. The authors used a 20% sample of national Medicare data to identify beneficiaries diagnosed with prostate cancer between January 2010 and December 2015 and followed them through 2016. They then linked urologists to their practices with tax identification numbers and patients to their practices based on their primary urologist. They identified 54,443 patients with incident prostate cancer, with most (87%) White and 9% Black. They found wide variation in racial practice composition and practice segregation. Patients in practices with the highest proportion of Black patients had the lowest socioeconomic status (43.1%), highest comorbidity (9.9% with comorbidity score ≥ 3), and earlier age at prostate cancer diagnosis (33.5% age 66-69 years). Black patients had lower odds of definitive therapy and underwent less treatment than White patients in every practice context. Black patients had lower predicted probability of treatment (66%) than White patients (69%).

Rural-urban disparities in receipt of surgery for potentially resectable non-small cell lung cancer.
This study examined the reasons there are lower rates of surgical treatment for potentially resectable non-small cell lung cancer (NSCLC) for patients living in rural areas than in urban areas. The National Cancer Database was used to identify patients with clinical stage I-IIIA NSCLC between 2004 and 2018. Reasons for nonreceipt of surgery was evaluated for rural and urban area patients. The study included 328,785 patients with NSCLC with 13% from rural areas. Overall, 62.4% of patients from urban areas and 58.8% of patients from rural areas underwent surgery. Patients from rural areas had increased odds of (1) being recommended primary nonsurgical management, (2) surgery being deemed contraindicated due to risk, (3) surgery being recommended but not performed, and (4) overall failure to receive surgery.

Extent of follow-up on abnormal cancer screening in multiple California public hospital systems: a retrospective review.
This report’s objective was to describes patterns of performance on follow-up of abnormal colon and breast cancer screening tests and explores the extent to which racial/ethnic disparities exist in public hospital systems. The authors conducted a retrospective cohort study using data from five California public hospital systems between July 2015 and June 2017. The authors assessed follow-up rates of colonoscopy after positive fecal immunochemical tests (FIT) and breast tissue biopsy within 21 days after a BIRADS 4/5 mammogram. Negative associations with follow-up colonoscopy were associated with older age, Medicaid insurance, lack of insurance, English language and site; while Hispanic ethnicity and Asian race were positively associated with follow-up colonoscopy. Of 1702 BIRADS 4/5 mammograms, 64% received a timely biopsy; only site was associated with timely follow-up biopsy. Site-level factors were found to have a larger, more consistent impact on follow-up rates than patient sociodemographic traits.

Absence of an anticipated racial disparity in interval breast cancer within a large health care organization.
The researchers sought to estimate the extent of an anticipated racial disparity in interval breast cancer (IBC) within a single, large health care organization. Contrary to expectation, in patient-adjusted models, there was no IBC racial disparity. The sorting of patients by race across facilities appears to have mitigated an otherwise anticipated disparity in IBC.
