Breast cancer diagnosis in Inner-City African American and Hispanic women: The importance of early screening.

PURPOSE: To evaluate the diagnosis of breast cancer in inner-city African-American and Hispanic women under age 50 to support the importance of screening in this population. METHODS: This retrospective chart review included women newly diagnosed with breast cancer from 1/1/2015 to 1/1/2019 in a city hospital mainly serving minority patients. Chi-square and Fisher's exact tests were used for analysis. RESULTS: In this cohort of 108 newly diagnosed African-American (63%) and Hispanic (31%) women, 60/108 (56%) presented with a site of palpable concern for diagnostic workup, and the remaining were diagnosed via asymptomatic screening. Women ages 30-49 were significantly more likely to present with a site of palpable concern when compared to women ages 50-69 (68% vs. 44%, p = 0.045). Additionally, women ages 30-49 were more likely to have triple-negative breast cancer (TNBC) than women ages 50-69 (20% vs. 10%, p = 0.222). However, women ages 30-49 were less likely to have prior mammogram than women ages 50-69 (24% vs. 46%, p = 0.062). CONCLUSION: African-American and Hispanic women ages 30-49 were more likely to present with a site of palpable concern and TNBC than those ages 50-69. However, these young minority women ages 30-49 were less likely to have prior screening mammograms when compared to those ages 50-69. Our data highlights the importance of starting screening mammography no later than age 40 in African-American and Hispanic women. In addition, these women should have risk assessment for breast cancer no later than age 30 and be screened appropriately.

COVID-19 Vaccine Effectiveness during a Prison Outbreak when Omicron was the Dominant Circulating Variant-Zambia, December 2021.

During a COVID-19 outbreak in a prison in Zambia from December 14 to 19, 2021, a case-control study was done to measure vaccine effectiveness (VE) against infection and symptomatic infection, when the Omicron variant was the dominant circulating variant. Among 382 participants, 74.1% were fully vaccinated, and the median time since full vaccination was 54 days. There were no hospitalizations or deaths. COVID-19 VE against any SARS-CoV-2 infection was 64.8%, and VE against symptomatic SARS-CoV-2 infection was 72.9%. COVID-19 vaccination helped protect incarcerated persons against SARS-CoV-2 infection during an outbreak while Omicron was the dominant variant in Zambia. These findings provide important local evidence that might be used to increase COVID-19 vaccination in Zambia and other countries in Africa.

Presentation of self-detected breast mass in minority women with limited access to care: Can self-examination assist in early cancer detection?

OBJECTIVE: The United States Preventive Services Task Force recommends against breast self-examination. However, racial disparities exist in mammogram screening. We aimed to evaluate the presentation of women with newly diagnosed breast cancer in the underserved African-American and Hispanic community to provide insight regarding breast cancer screening in this population. METHODS: This retrospective cohort study included women newly diagnosed with breast cancer from 1/1/2016 to 1/1/2018 in an inner city public community hospital. Data was collected via chart review. Patients were divided based on whether they presented with self-detected breast mass. Logistic regression was used for analysis. RESULTS: 59 women were newly diagnosed with breast cancer. 34 women (58%) were African-American, 20 (34%) were Hispanic, and 5 (8%) were other race. Of 59 women, 36 (61%) presented with self-detected breast mass, and only 21 (36%) reported prior mammography. For women who presented with breast mass, the odds of having prior mammography were 78% lower (OR = 0.22, 95% CI 0.07-0.69, p = 0.009), while the odds of having invasive ductal carcinoma were 4.33 times higher (OR = 4.33, 95% CI 1.09-17.25, p = 0.037), as compared to the odds for women not presenting with breast mass. CONCLUSION: Many of our newly diagnosed breast cancer patients were African-American or Hispanic women presenting with self-detected breast mass without prior screening mammography. Further studies should evaluate whether supplemental screening methods, such as breast self-examination or clinical examination, can help with early breast cancer detection in minority women with limited access to care, and such disparities should be considered by organizations when creating screening guidelines.
