Stage IV breast, colorectal, and lung cancer at diagnosis in adults living with intellectual or developmental disabilities: A population-based cross-sectional study.

BACKGROUND: Cancer is a leading cause of death among people living with intellectual or developmental disabilities (IDD). Although studies have documented lower cancer screening rates, there is limited epidemiological evidence quantifying potential diagnostic delays. This study explores the risk of metastatic cancer stage for people with IDD compared to those without IDD among breast (female), colorectal, and lung cancer patients in Canada. METHODS: Separate population-based cross-sectional studies were conducted in Ontario and Manitoba by linking routinely collected data. Breast (female), colorectal, and lung cancer patients were included (Manitoba: 2004-2017; Ontario: 2007-2019). IDD status was identified using established administrative algorithms. Modified Poisson regression with robust error variance models estimated associations between IDD status and the likelihood of being diagnosed with metastatic cancer. Adjusted relative risks were pooled between provinces using random-effects meta-analyses. Potential effect modification was considered. RESULTS: The final cohorts included 115,456, 89,815, and 101,811 breast (female), colorectal, and lung cancer patients, respectively. Breast (female) and colorectal cancer patients with IDD were 1.60 and 1.44 times more likely to have metastatic cancer (stage IV) at diagnosis compared to those without IDD (relative risk [RR], 1.60; 95% confidence interval [CI], 1.16-2.20; RR, 1.44; 95% CI, 1.24-1.67). This increased risk was not observed in lung cancer. Significant effect modification was not observed. CONCLUSIONS: People with IDD were more likely to have stage IV breast and colorectal cancer identified at diagnosis compared to those without IDD. Identifying factors and processes contributing to stage disparities such as lower screening rates and developing strategies to address diagnostic delays is critical.

Interventional Radiology Workforce Shortages Affecting Small and Rural Practices: A Report of the SIR/ACR Joint Task Force on Recruitment and Retention of Interventional Radiologists to Small and Rural Practices.

Radiology practices characterized as small and rural are challenged to recruit and retain interventional radiologists. Lack of access to interventional radiologic services results in a failure to meet the needs of patients, hospitals, and other community stakeholders. Acknowledging this challenge, the ACR's Commission on General, Small, Emergency and/or Rural Practice and Commission on Interventional and Cardiovascular Imaging and the Society of Interventional Radiology partnered to establish a joint task force to study this issue and identify strategies the ACR and the Society of Interventional Radiology should take to improve small and rural practice recruitment and retention of interventional radiologists. This report describes the deliberations and recommendations of the task force.

What's in a Name? Report of the ACR Task Force on General Radiology and Multi-Subspecialization.

The ACR Council passed Resolution 47 at its 2020 annual meeting establishing a representative task force (TF) to explore the concept of the "multispecialty radiologist," previously proposed in 2012. The TF held eight virtual meetings over 8 months, considered data from a 2020 ACR Membership Tracking Survey, conducted a review of current literature, and collected anecdotal experience from TF members and ACR leadership. ACR legal counsel and a cross-section of ACR Commissions and Committees also provided input. The TF concluded that there is scant interest from the radiology community in the multispecialty radiologist title and no agreed-upon definition for the term. Radiologists may identify as diagnostic or subspecialty radiologists; however, the roles they fill in clinical practice include general, multispecialty, and subspecialized radiology. The TF proposes definitions for each of these terms to support radiologist recruitment aligned with optimal patient care in the practice community and to improve the quality of data collection about the field. To reduce ambiguity, the TF proposes adoption of the defined terms by the radiology community, including radiologist recruiters and employers, and suggests ways in which resident training and the ABR board examination can be adapted to support this new structure. Additionally, as part of an exploration of hyperspecialization and trainee preparedness for clinical practice, the TF discussed the challenges faced by community-based practices seeking to provide a full range of high-quality, radiologist-delivered diagnostic and interventional services to their patient populations.

Age distributions of breast cancer diagnosis and mortality by race and ethnicity in US women.

BACKGROUND: Surveillance, Epidemiology, and End Results (SEER) data from 1973-2010 have been used to show that minority women have disproportionately higher percentages of breast cancers diagnosed at younger ages in comparison with White women. METHODS: The authors analyzed SEER 21 invasive breast cancer incidence data for 2014-2017 and National Center for Health Statistics mortality data for 2014-2018 and compared invasive incidence and mortality by age in non-Hispanic Black (NH-Black), Asian American/Pacific Islander (AAPI), Native American, and Hispanic women with those in non-Hispanic White (NH-White) women. They evaluated incidence rates and percentages of invasive breast cancer cases and breast cancer deaths occurring before the age of 50 years along with advanced-stage incidence rates and percentages in minority women versus NH-White women. RESULTS: Recent SEER data showed that invasive breast cancers were diagnosed at significantly younger ages in minority women versus NH-White women. Among women diagnosed with invasive breast cancer, compared with NH-White women, minority women were 72% more likely to be diagnosed under the age of 50 years (relative risk [RR], 1.72; 95% confidence interval [CI], 1.70-1.75), 58% more likely to be diagnosed with advanced-stage breast cancer under the age of 50 years (RR, 1.58; 95% CI, 1.55-1.61), and 24% more likely to be diagnosed with advanced-stage (regional or distant) breast cancer at all ages (RR, 1.24; 95% CI, 1.23-1.25). Among women dying of breast cancer, minority women were 127% more likely to die under the age of 50 years than NH-White women. CONCLUSIONS: NH-Black, AAPI, Native American, and Hispanic women have higher proportions of invasive breast cancers at younger ages and at advanced stages and breast cancer deaths at younger ages than NH-White women. LAY SUMMARY: This study analyzes the most recently available data on invasive breast cancers and breast cancer deaths in US women by age and race/ethnicity. Its findings show that non-Hispanic Black, Asian American/Pacific Islander, Native American, and Hispanic women have a higher percentage of invasive breast cancers at younger ages and at more advanced stages and a higher percentage of breast cancer deaths at younger ages than non-Hispanic White women.

Racial and Ethnic Disparities in Breast Cancer: A Collaboration Between the American College of Radiology Commissions on Women and Diversity and Breast Imaging.

Since the 1980s, the mortality rate from breast cancer in the United States has dropped almost 40%. The quality of life and survival gains from early detection and improved treatment have not been shared equally by all ethnic groups, however. Many factors, including social determinants of health, unequal access to screening and oncologic care, and differences in incidence, tumor biology, and risk factors, have contributed to these unequal breast cancer outcomes. As breast radiologists approach their own patients, they must be aware that minority women are disproportionately affected by breast cancer at earlier ages and that non-Hispanic Black and Hispanic women are impacted by greater severity of disease than non-Hispanic White women. Guidelines that do not include women younger than 50 and/or have longer intervals between examinations could have a disproportionately negative impact on minority women. In addition, the COVID-19 pandemic could worsen existing disparities in breast cancer mortality. Increased awareness and targeted efforts to identify and mitigate all of the underlying causes of breast cancer disparities will be necessary to realize the maximum benefit of screening, diagnosis, and treatment and to optimize quality of life and mortality gains for all women. Breast radiologists, as leaders in breast cancer care, have the opportunity to address and reduce some of these disparities for their patients and communities.

Breast conserving therapy with accelerated partial breast versus external beam whole breast irradiation: comparison of imaging sequela and complications in a matched population.

Our purpose was to evaluate and compare the imaging sequela and complications of accelerated partial breast irradiation (APBI) with those occurring in patients treated with standard external beam therapy. Patient selection included those who met the criteria for possible ABPI: age 45 or older; cancer stage T1N0M0 or ductal carcinoma in situ 3 cm or less, and negative surgical margins. One hundred and ninety seven had complete records and films available for review. Ninety-seven (49%) were treated with APBI (MammoSite) and 100(51%) were treated with external beam. Image findings for APBI versus external beam were: distortion 90(93%) versus 83(83%), seroma 67(69%) versus 7(7%), skin edema 52(54%) versus 47(47%), increased stroma 75(77%) versus 66(66%), calcifications 10(10%) versus 6(6%), and fat necrosis 12(12%) versus 6(6%). For APBI, skin and stromal edema was more commonly focal. At imaging, the seroma rate was statistically and significantly different between the two treatment modes (p < 0.0001). For patients treated with APBI, seroma formation was not related to balloon size and only weakly related to lumpectomy cavity size. The complication rate was significantly higher for those treated with APBI (36 versus 20%) and the types and treatment of complications differed. There were three recurrences among the APBI group and none among those treated with external beam radiation.
