The July 2021 issue of Cancer Epidemiology, Biomarkers & Prevention includes a report detailing a geospatial analysis showing that those who live in rural areas, have limited access to transportation, and are Hispanic are far more likely to fall far below the national average for Human papillomavirus (HPV) vaccination.

According to the paper, Identifying Area-Level Disparities in Human Papillomavirus Vaccination Coverage Using Geospatial Analysis, HPV is the most common sexually transmitted disease in the U.S. HPV can lead to a variety of cancers, many of which are more prevalent among African and Hispanic Americans.

An HPV vaccine, which can effectively prevent both HPV and HPV-associated cancers, is readily available throughout the U.S. However, these researchers determined that the availability of the HPV vaccine “is suboptimal and varies by geographic region,” specific poor rural regions with a high percentage of Hispanic residents.

The research team, led by David Wheeler, M.P.H., PhD of the VCU Massey Cancer Center, sought to “model the variation in vaccination rates among boys and girls within ZIP Codes in Virginia, determine whether neighborhood sociodemographic variables explain variation in HPV vaccination, and identify areas with significantly depressed vaccination coverage.”

According to the VCU research team: “The results showed low vaccination coverage in our birth cohort (28.9% in girls and 23.8% in boys) relative to the national level (56.8% and 51.8%, respectively). Several area-level variables were significantly and positively associated with vaccination coverage, including population density, percentage of Hispanic population, and average number of vehicles. In addition, there were several areas of significantly lowered vaccination coverage, including predominantly rural ones, and overall large geographic disparities in HPV vaccination.”

According to a Centers for Disease Control and Prevention Fact Sheet on HPV and Cancer, Hispanic and African American women both have higher rates of HPV-associated cervical cancer than women of other races and non-Hispanic women.

  • While rare, HPV-associated vaginal cancers are more prevalent among African American women, while HPV-associated vulvar cancers are more common among White women.
  • While also rare, Hispanic men had higher rates of HPV-associated penile cancer than non-Hispanic men.
  • In all races and ethnicities, men had higher rates of HPV-associated cancers of the oropharynx (back of the throat, including the base of the tongue and tonsils) than women. Black and Hispanic men and women had lower rates of HPV-associated oropharyngeal cancers than White and non-Hispanic men and women.

 

According to a Massey Cancer Center press release describing this research project, Dr. Wheeler said: “Several socio-economic variables were significantly and positively associated with vaccination coverage, including population density, percent Hispanic population and average number of vehicles. Despite being one of the few states to mandate vaccination of females for school entry, the overall rate of HPV vaccine coverage within Virginia remains low compared to the national average.”

“This is What Dignity Looks Like”

First anniversary of Chadwick Boseman’s death from a disease that is devastating to the African American community

Son of Inequity

August 28, 2021, will mark the one-year anniversary of the tragic death of actor Chadwick Boseman, who died at age 43 from colorectal cancer (CRC): a disease with one of the largest racial disparity gaps—for both incidence and fatalities—in the United States.

Boseman, who starred in many block-buster films—portraying Jackie Robinson in “42”, Thurgood Marshall in “Marshall”, James Brown in “Get On Up,” and, of course, T’Challa in “Black Panther”—was diagnosed with Stage 3 CRC in 2016.

The premature death of this private man and gifted actor caught a nation off guard. Countless fans mourned publicly on social media, along with many celebrities, including Oprah Winfrey who said the following about Boseman’s battle with CRC:

“Showing us all that greatness in between surgeries and chemo, he had the courage, the strength, the Power it takes to do that. This is what Dignity looks like.”

While great disparities exist by race in the diagnosis and outcomes of many cancers, few are as stark as CRC. According to the National Cancer Society, African Americans are about 20% more likely to get CRC and about 40% more likely to die from CRC than most other groups in the U.S.

Colorectal cancer and the high human cost of inequality of care

“Collectively, blacks have the highest death rate and shortest survival of any racial/ethnic group in the U.S. for most cancers. Black men also have the highest cancer incidence rate. The causes of these inequalities are complex and reflect social and economic disparities and culture differences that affect cancer risk as well as differences in access to high-quality health care, more than biological differences. Moreover, black men and women bear a disproportionately high burden of other diseases, which influences cancer survival. In 2016, the death rate in the U.S. was higher for blacks than whites for heart disease, stroke, influenza and pneumonia, diabetes, hypertension, HIV/AIDS, kidney disease and homicide. Consequently, life expectancy is lower for blacks than whites among both men (71.5 versus 76.1 years and women (77.9 versus 81.0 years).”

From the American Cancer Society’s report “Cancer Facts & Figures for African Americans 2019-2021” :

 

The ACS report documents the following:

African Americans have the highest rates of CRC compared to all other racial groups in the U.S.

CRC is the third most common cancer in the African American community.

When compared to non-Hispanic Whites, the incidence of CRC is 24 percent higher in non-Hispanic Black males and 19 percent higher in non-Hispanic Black females.

CRC death rates are 47 percent higher in non-Hispanic Black men and 34 percent higher in non-Hispanic Black women, when compared to non-Hispanic White men and women.

Studies indicate that 19% of this racial disparity in fatalities from CRC can be attributed to lower screening rates and 36 percent to lower stage-specific survival among African Americans in general.

Like the incidence of CRC, deaths from this malignancy were highest in White patients in the U.S. until 1979 for women and 1984 for men when the fatality rates for White Americans dropped below that for African Americans.

For African Americans, the 5-year survival rate for CRC increased from 45 percent in 1975-1977 to 58 percent in 2008-2014, while the 5-year survival rate grew from 50 percent to 67 percent over the same time period for White Americans.

  • There are many of the lifestyle and risk factors that promote CRC:
    • Excess body weight
    • Physical inactivity
    • Long-term smoking
    • Diets rich in red meat or processed meats and poor in fresh fruit, vegetables and whole-grain fiber
    • Low-calcium diets
    • Moderate to heaving alcohol consumption
    • Diabetes
    • Hypertension
  • Several of these risk factors disproportionately affect African Americans, including excess body weight, long-term smoking and the prevalence of diabetes and hypertension.
  • While survival rates are increasing, the disparity is believed to be due to the fact that African Americans are diagnosed at a later stage of the disease.
    • For African Americans with CRC, 37 percent are initially diagnosed with local-stage disease, which is an early diagnosis with a better prognosis. For White CRC patients, 39 percent are diagnosed at this early stage.
    • The disparity in stage-specific survival rates is due to differences in treatment, comorbidities and tumor characteristics.
    • African American patients diagnosed with CRC are less likely than White CRC patients to receive recommended surgical, chemotherapeutic and radiation therapies.
    • In the setting of a clinical trial where treatments are implemented equally, the Black-White survival disparity shrank dramatically.
  • A recent study conducted by ACS researchers found that access to care, which is dictated by insurance status, is to blame for half of the CRC survival gap between African American and White CRC patients under age 65.
  • According to the ACS, 26 percent of the survival disparity in patients under the age of 65 is due to something outside the control of equitable diagnosis and care: “unfavorable tumor characteristics.”
    • For patients older than 65, nearly 50 percent of the survival disparity is due to unfavorable tumor characteristics.
    • To illustrate these characteristics, the ACS states that African American CRC patients are as much as four times more likely than White CRC patients to be diagnosed with proximal (right-sided) tumors.
    • CRC tumor side is associated with significant differences in molecular features that make proximal tumors more difficult to treat.

 

Screening is the key to survival

  • Early screening is the key to survival because CRC is very treatable if caught early so it is not surprising to learn that there is a screening disparity between African Americans and White Americans, as well.
    • Up until 1989, White males had a higher rate of CRC than African American males, while females had the same rate of this disease at that time.
    • But in the ensuing 30 years, rates increased for African Americans and decreased for White Americans.
    • This “crossover,” according to the ACS, may reflect racial differences in the trends of risk factors for colorectal cancer and/or greater access to and utilization by White Americans of recommended screening tests that detect and remove precancerous polyps.
    • This is incredibly significant because screening tests that allow for the early removal of adenomatous polyps are the best tools and most effective method to prevent polyps from developing into CRC tumors.
    • CRC screening increased from 32 percent to 62 percent in African Americans over the age of 50 from 2000 to 2015.
    • Screening rates for White Americans the same age and over the same time period increased from 40 percent to 65 percent.
    • According to one recent study, 53 percent African Americans were up to date with their CRC screening while 56 percent of White Americans were considered up to date with screening recommendations.
    • An ACS study concluded that African Americans were 30 percent more likely than Whites to be diagnosed with an interval cancer following a negative colonoscopy but before the next recommended screening.
    • This may be the case because the same study found that African Americans are more likely than White Americans to receive colonoscopies from “less-skilled physicians.”

Advanced CRC being diagnosed in younger patients

While several indicators show that equity in screening and care is narrowing the CRC incidence and fatality gap between African and White Americans, one striking statistic still persists, and it very relevant in the loss of Chadwick Boseman: Younger and younger American patients are being diagnosed with advanced CRC.

“Colorectal cancer is the second deadliest cancer in the country. This disease is ravaging the Black community, and it is as important as ever that everyone has access to and is receiving the recommended screenings. Even during the coronavirus pandemic, necessary screening tests remain available to prevent the disease or find it at an early, more treatable stage.”

Durado Brooks, MD, VP of Prevention and Early Detection, American Cancer Society

One recent research paper,  Colorectal Cancer in Young African Americans: Is it time to revisit guidelines and prevention? discusses this ominous trend:

“CRC incidence is increasing among the young in all racial groups under study. This increase in frequency of CRC is true among young African American adults who display highly advanced tumors in comparison to other races. While the present attention to screening seems to have decreased CRC prevalence in individuals older than 50, special attention needs to be addressed to young African American adults as well, to counter the observed trend, as they have the highest incidence of CRC among young population groups by race/ethnicity.“

Wisconsin Health News recently hosted an online forum on disparities in healthcare availability and quality faced by the minorities of that state.  Below are some of the persistent inequities discussed during the July 13, 2021, forum:

The infant mortality for African American newborns is higher than the average in Wisconsin, a tragic reality that unfortunately reflects a national trend.

According to the Centers for Disease Control and Prevention, infant mortality is a far greater risk for African American babies than for newborns of every other ethnicity. According to the CDC, the infant mortality rates (per 1,000 live births) in the U.S. by race and ethnicity are as follows:

 

  • Non-Hispanic black: 10.8
  • Native Hawaiian or other Pacific Islander: 9.4
  • American Indian/Alaska Native: 8.2
  • Hispanic: 4.9
  • Non-Hispanic white: 4.6
  • Asian: 3.6

 

According to the March of Dimes, the infant mortality rates by race in Wisconsin (2016 to 2018) significantly exceeded the national averages, particularly for African and Native American residents of Wisconsin (per 1,000 live births):

 

  • White: 5.0
  • African American: 14.4
  • American Indian/Alaska Native: 10.5
  • Asian/Pacific Islander: 6.5

 

African American mothers in Wisconsin have an elevated risk of complications and death from childbirth. A 2020 CDC National Center for Health Statistics report on deaths from childbirth also reflect a dramatic racial disparity:

  • The maternal mortality rate in the U.S. for 2018 was 17.4 maternal deaths per 100,000 live births.
  • This rate is higher than the last time NCHS published a national rate (12.7 in 2007), but the increase in the maternal mortality rate largely reflects changes in the way the data was collected and reported.
  • 658 women died of maternal causes in the U.S. using the 2018 coding method.
  • Wide racial/ethnic gaps exist between non-Hispanic black (37.1 per 100,000 live births), non-Hispanic white (14.7), and Hispanic (11.8) women, which is consistent with earlier data.
  • The maternal mortality rate for women aged 40 and over (81.9 per 100,000 live births) is nearly 8 times that for women under age 25 (10.6).

 

Life expectancy for Black women is declining faster compared to white women. The CDC, as well as numerous independent studies, have shown that the pandemic has driven down the average American life expectancy by more than 12 months. Advocates at the July 13 Wisconsin disparities symposium pointed out that this burden is disproportionately harming African Americans.

Life expectancy declined by 2.3 years for African American women and 3 years for African American men due to the pandemic, with declines of 1.5-2 years for White Americans.

Researchers from Virginia Commonwealth University (VCU) conducted a sweeping analysis of the impact of Covid-19 on the U.S. and 16 other comparable nations and found that U.S. life expectancies dropped dramatically compared with these “peer countries,” with significant drops in the life expectancies of both African and Hispanic Americans.

The paper, titled “Effect of the covid-19 pandemic in 2020 on life expectancy across populations in the USA and other high-income countries: simulations of provisional mortality data,” published in the June 24 2021 issue of the British Medical Journal, compared the impact of the pandemic of life expectancy in the U.S. and peer countries of comparable wealth and access to advanced healthcare.

As the authors explain: “Peer countries included 16 high income democracies with adequate data for analysis: Austria, Belgium, Denmark, Finland, France, Israel, Netherlands, New Zealand, Norway, South Korea, Portugal, Spain, Sweden, Switzerland, Taiwan, and the United Kingdom.”

Even prior to Covid, the researchers found the U.S. lagging behind this peer group in average life expectancy: “Between 2010 and 2018, the gap in life expectancy between the US and the peer country average increased from 1.88 years (78.66 v 80.54 years, respectively) to 3.05 years (78.74 v 81.78 years).”

The ominous trend accelerated during the peak of the pandemic, the research found: “Between 2018 and 2020, life expectancy in the US decreased by 1.87 years (to 76.87 years), 8.5 times the average decrease in peer countries (0.22 years), widening the gap to 4.69 years.” But the most staggering decreases in life expectancy occurred among Hispanic and African Americans, according to the VCU analysis:

“Life expectancy in the US decreased disproportionately among racial and ethnic minority groups between 2018 and 2020, declining by 3.88, 3.25, and 1.36 years in Hispanic, non-Hispanic Black, and non-Hispanic White populations, respectively. In Hispanic and non-Hispanic Black populations, reductions in life expectancy were 18 and 15 times the average in peer countries, respectively. Progress since 2010 in reducing the gap in life expectancy in the US between Black and White people was erased in 2018-20; life expectancy in Black men reached its lowest level since 1998 (67.73 years), and the longstanding Hispanic life expectancy advantage almost disappeared.”
