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.

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.

Cancer surveillance and preventive services in a diverse sample of breast and colorectal cancer survivors.
This study assessed engagement in surveillance for recurrence, cancer screening, and other recommended preventive health services among breast and colorectal cancer survivors with early-onset disease (age 50 years and younger) who were diagnosed in California. Findings showed that, although the majority of survivors received appropriate surveillance for recurrence, engagement in other preventive health services varied substantially. Implications included efforts to address gaps in the use of recommended cancer screening and preventive health services among cancer survivors.

Primary care provider involvement in thyroid cancer survivorship care.
While prior research has examined how primary care providers (PCPs) can care for breast and colon cancer survivors, little is known about their role in thyroid cancer survivorship. The purpose of this study was to understand PCP involvement and confidence in thyroid cancer survivorship care. The investigators found that while PCPs reported being involved in long-term surveillance, gaps remained in their confidence in handling survivorship care. They indicated that thyroid cancer survivorship guidelines that delineate PCP roles present one opportunity to increase confidence about their participation.

Association of Medicaid expansion under the Affordable Care Act with insurance status, cancer stage, and timely treatment among patients with breast, colon, and lung cancer.
The effect of the Patient Protection and Affordable Care Act's Medicaid expansion on cancer care delivery and outcomes is unknown. Patients with cancer are a high-risk group for whom treatment delays are particularly detrimental. The objective of this study was to examine the association between Medicaid expansion and changes in insurance status, stage at diagnosis, and timely treatment among patients with incident breast, colon, and non-small cell lung cancer.

Risks of developing breast and colorectal cancer in association with incomes and geographic locations in Texas: a retrospective cohort study.
This study aimed to determine whether median household income was associated with the risk of developing breast and colorectal cancer in Texas and to identify higher cancer risks by race/ethnicity and geographic areas. It demonstrated that higher income was associated with an increased risk of breast cancer and a decreased risk of colorectal cancer in Texas.

Patient and provider characteristics associated with colorectal, breast, and cervical cancer screening among Asian Americans.
The researchers performed multivariable modeling to evaluate potential predictors (at the provider- and patient-level) of screening completion among Asian patients. They concluded that language- and gender-concordant primary care providers and culturally tailored online health resources may help improve preventive cancer screening in Asian patient populations.
