6. Breast Cancer Exemplifies Inequitable
Allocation
In USA and EU effectively being controlled in up to 80% of some
populations of women
However, breast cancer is leading cause of cancer death in most nonwhite women around the world (including US) 6
Why this disparity between white non-Hispanic women and non-white
women in breast cancer deaths?
Reasons explored in a joint study of University of Massachusetts and
Johns Hopkins in an international horizon scanning study in breast
cancer, from 2006 to 20087

8. UMass/Johns Hopkins Horizon Scanning Study7
Part of this difference for ethnically diverse groups is attributed to
differences in:
Lifestyle and cultural attitudes
Lack of prevention and early detection
Lack of education and advocacy
Issues related to access to care
Affordability
Environmental factors
Genetics
Most of the countries involved in the study noted they lacked the
resources and know-how to conduct adequate research. 8,9

work for ethnically diverse and economically challenged populations.”
NCCN and other cancer guidelines mainly are based upon research done in
white populations and may not be appropriate
If treatment guidelines don’t work in ethnically diverse and economically
challenged populations outside of the USA, they also are unlikely to work in
similarly challenged populations within the USA
A significant need and opportunity exists for greater diversity in cancer,
epidemiology, socioeconomics and related research in order to formulate
success strategies and policies to control cancer in America’s increasingly
culturally and ethnically diverse populations
10. Cancer in Different Ethnicities in USA:
Hispanics
Compared to non-Hispanic Caucasian populations:
Both Hispanic men and women are twice as
likely to have and die from liver cancer
Hispanic women are 2.7 times more likely to
have stomach cancer
Hispanic women are twice as likely to have
cervical cancer, and 1.5 times more likely to die
from cervical cancer

11. Cancer in Different Ethnicities in US:
Asians/Pacific Islanders
Compared to non-Hispanic Caucasian populations:
Asian/Pacific Islander men are twice as likely to
die from stomach cancer
Asian/Pacific Islander women are 2.6 times as
likely to die from the same disease
Both Asian/Pacific Islander men and women
have three times the incidence of liver &

12. Cancer in Different Ethnicities in US:
African Americans
African Americans have the highest mortality rate of
any racial and ethnic group for all cancers combined
and for most major cancers
Compared to non-Hispanic Caucasian populations:
African American men are twice as likely to have
new cases of stomach cancer
African American women are 10% less likely to
have been diagnosed with breast cancer,
however, they were 34% more likely to die from
breast cancer

13. Differences in Breast Cancer by Race & Ethnicity
In US, mean age of breast cancer diagnosis:
•
American Indian - 54 ±13
•
Hispanic - 56 ±14
•
Asian/Pacific Islanders - 57±13
•
Blacks - 57± 17
•
Whites [Caucasians] - 62 ±14
Blacks, American Indians, and Hispanics:
•
had 1.7 to 2.5 fold increase risk of stage III and stage IV breast tumors
•
had 1.3 to 2 fold greater risk of breast cancer related mortality
In stage I or II breast cancer patients with tumors smaller than 5.0 cm, Blacks, other
Asians and Pacific Islanders, Mexicans, and Puerto Ricans were 20% to 50% more
likely to receive inappropriate primary surgical and radiation breast cancer
treatment

14. Ethnic Challenges in Cancer Research and Care
Some examples of mistrust, fear, social and other cultural beliefs:
• Some fear genetic research in case they may be considered
unmarriageable8
• If people knew they had “cancer genes” they will consider cancer
“inevitable” and therefore not try to adopt healthier lifestyles 14
• Chinese may be reluctant to try to be part of any research for fear of
learning they have and being rejected due to HBV/HCC 15
• In Africa, people are reluctant to participate in cancer research because
they fear learning that they have HIV and other diseases. 16
• In some countries, women chose to have breast cancer or delay seeking
treatment, for fear of losing their hair or surgical disfigurement 7

15. Some Further Examples of Disparities
Studies on communications with patients
• Oncologists appear to communicate differently with breast cancer patients, depending
on the women's race, age, and other factors 17
• Poor communication of mammogram results may explain disparities in breast cancer
diagnosis and outcomes18
Studies on screening and treatment
• Poor, minority, and uninsured individuals have reduced access to screening and surgery
for colorectal cancer19
• Perceived racial discrimination in adherence to screening mammography guideline 20
• Minority women are less likely to receive adjuvant therapies following breast cancer
surgery21
• Disparities in receipt of chemotherapy following ovarian cancer surgery 22
• Socioeconomic barriers exist to timely diagnosis and treatment of prostate cancer in
black men23

16. Clinical Trials Lack Ethnically Diverse
Representation
Clinical Trials
• Fewer than 10% of U.S. clinical trial participants come from AfricanAmerican, Latino, and Asian populations 24

17. Barriers to Clinical Trials Result in
Underrepresentation of Non-Caucasians
Participant Barriers to Participation:
• Mistrust
• Lack of awareness
• Cultural barriers
• Language/Linguistic differences
• Socioeconomic obstacles
• Cost/Lack of insurance
• Study design eligibility criteria

18. Barriers to Clinical Trials Result in
Underrepresentation of non-Caucasians
Physician/Investigator Barriers to Referring Participants
to Clinical Trials:
•Lack of non-Caucasian investigators
•Lack of physician referral
•Lack of physician awareness
•Participants are also often excluded from clinical trials
due to characteristics, preferences, and circumstances
of the physicians who conduct or refer patients to
clinical trials

19. Opportunities to Increase Diverse Ethnicity
Participation in Clinical Trials
Physician’s ethnicity is an important factor in influencing patient
participation in a clinical trial
• Black and Latino (and some Asian) physicians are more likely to treat
patients of a similar race and ethnicity 26
Issue of underrepresentation of African Americans in research implies that
more minority physicians should be recruited into clinical research [and
into cancer specialties]. 26
Over 85% of communications on participation in clinical trials by both US
government (NCI, NIH and others) and the major pharmaceutical
companies found to be only available in English. 27
• Fewer than 10% were bi-lingual (and almost none multilingual)

20. Influence of Health Insurance and
Socioeconomic Status (SES)
As of 2009, 1:4 non-Caucasian in the USA will forego the cancer treatment due to
costs (1:8 in overall population)
In a breast cancer study, women who were uninsured or had Medicaid coverage
compared to those who had Medicare or private insurance were 65% less likely to
receive adjuvant treatment28
Researchers compared black and white men diagnosed with prostate cancer from
the North Carolina Cancer Registry23
Both had to travel similar distances for health care 23
Black men still had less access to care23
Also had poorer health insurance coverage and less continuity of care,
used more public clinics and emergency wards, and expressed less trust in
their physicians23
Conclusion: Barriers to early diagnosis and appropriate care for prostate cancer
among black men were related more to SES than to lack of education or
cultural misunderstanding23

21. Influence of Health Insurance and
Socioeconomic Status (SES)
In 2008, research in women with ovarian cancer showed those of higher
SES had increased use of surgery and chemotherapy; women in the lowest
quartile of SES were more likely to die than those in the highest quartile 22
In colorectal cancer, a 2007 study demonstrated that poor, minority and
uninsured individuals have reduced access to screening and surgery for
colorectal cancer, independent of other patient characteristics. 23
It is important to recognize that when policy for cancer control is
formulated for diverse ethnicities, in many cases this may present
additional challenges not only in terms of socioeconomic status, but also
access to health care insurance
Percentage of uninsured Americans by race29:
White Americans - 11%
Asians – 18%
Blacks - 19%
Hispanics - 31%

22. Cancer Control Must Start with Prevention
The President’s Cancer Panel already has identified tobacco and obesity
reduction as important to cancer prevention, 30 as has the American Cancer
Society.31
Obesity and physical inactivity may account for 25% to 30% of several
major cancers, including cancer of the gall bladder, ovaries and pancreas. 32
Obese people may have a 19 % higher risk of pancreatic cancer than those
with a normal BMI 33
• Obesity may also correlate to the higher pancreatic cancer risk among
black Americans.34

25. Obesity in America
African Americans were 1.4 times as likely to be obese as non-Hispanic
Caucasians
Hispanic adults were 50% less likely to engage in active physical activity as nonHispanic Whites
African American women have the highest rates of being overweight or obese
compared to other groups in the U.S.
•
About four out of five African American women are overweight or obese
73 percent of Mexican American women are overweight or obese compared to
61.6 % of the general female population
Minority women with low income appear to have the greatest likelihood of
being overweight
Among Mexican American women, age 20 to 74, the rate of overweight is about 13 percent
higher for women living below the poverty line versus above the poverty line

26. Obesity Increases the Risk of Cancer
Obesity and physical inactivity may account for 25 to 30% of several
major cancers32
In 2002, about 41,000 new cases of cancer in the US were estimated
due to obesity 36
In the US, 14% of death from cancer in men and 20% deaths in women
may be due to overweight and obesity37

27. Immigrants Face Increasing Risk of Cancer31
Cancer Rates for Hispanics in Florida were at least 40% higher than Hispanics
in their countries of origin38
Among Cubans and Mexicans in Florida, the risk for colorectal cancer was more than double
the risk in Cuba and Mexico. The same was true for lung cancer among Mexican and Puerto Rican
women in Florida compared with women in their homelands38
"There is no reason to believe that the people who came to Florida from the Latin countries are
different from those who stayed," said Dr. Paulo S. Pinheiro, a researcher in the university's
department of epidemiology. "Since there is no genetic difference, if there is a difference it will
be in the lifestyles they adopt once they come to the United States." 38
Cancer expert Vilma Cokkinides agrees that unhealthy lifestyle changes increase the cancer risk
for Hispanic immigrants. "Immigrants who come and stay longer in the United States start
adopting lifestyles that can lead to greater cancer incidents," said Cokkinides, strategic director of
risk factor surveillance at the American Cancer Society. "Smoking, diet, lack of physical activity
and exposure to certain chemicals tend to lead to a higher risk of cancer.“38

33. THE GOOD NEWS…
• Need for new policies and practices to be developed
to better control cancer in America’s increasingly
culturally and ethnically diverse nation
• America does not have to learn on its own
• It has much to learn from the rest of the world as the
world may learn from it
• As a result, when the US succeeds in achieving better
control of cancer across its rich and diverse
population; everyone - not only in the US, but in the
world - will benefit.
Oncologists appear to communicate differently with breast cancer patients, depending on the women's race, age, and other factors: Researchers audio-taped initial consultations between 58 oncologists at 14 practices with 405 women newly diagnosed with breast cancer and conducted interviews with patients and physicians immediately before and after the visits. They found that oncologists spent more time engaged in building relationships with white patients than with members of other racial/ethnic groups. The women who asked more questions were younger, white, had more education, and had a higher income. Physicians tended to ask these women more questions than they did other women. Racial differences occurred in almost every communication category examined, potentially leading to disparities in breast cancer outcomes.

Poor communication of mammogram results may explain disparities in breast cancer diagnosis and outcomes: Researchers surveyed 411 black and 734 white women who had screening mammograms at five hospital-based facilities in Connecticut between 1996 and 1998 and found no difference between the two groups of women in the proportion of abnormal screening mammograms. However, communication of mammogram results was problematic for 14.5 percent of the women; 12.5 percent had not received their results, and 2 percent had received their results but their self-report differed from the radiology record. Inadequate communication of mammogram results was nearly twice as common among black women as among white women

Poor, minority, and uninsured individuals have reduced access to screening and surgery for colorectal cancer: Three studies supported by AHRQ examined trends in colorectal cancer screening and access to surgery and found that low-income/poor individuals, the uninsured, and minorities are screened less frequently than others for colorectal cancer, and they are more likely to need emergency surgery for colorectal cancer-related problems such as bowel perforation, peritonitis, or bowel obstruction. Also, patients who were black, Hispanic, Asian, or less affluent and those who had more advanced colorectal cancer were more likely than white, more affluent, and less severely ill patients to have surgery for the condition at hospitals with above average mortality rates. The researchers conclude that there continue to be barriers to highquality surgical care for minority individuals with colorectal cancer, independent of other patient characteristics.

Study examines effects of perceived racial discrimination in adherence to screening mammography guidelines: Researchers examined receipt of index mammograms at one of five urban hospitals in Connecticut between 1996 and 1998 among 484 black women and 745 white women to identify any links between perceived racial discrimination and black women's adherence to screening mammography guidelines. About 42 percent of black women and 10 percent of white women reported discrimination at some point in their lives, but this perceived discrimination was not associated with nonadherence to age-specific mammography screening guidelines, even after adjusting for other factors. The researchers caution that black women in the study may have underreported discrimination due to the sensitive nature of the topic and their discomfort in talking about it with white phone interviewers. If this is the case, these findings may underestimate its prevalence and effects on regular mammography screening.

Racial disparities in receipt of breast-conserving therapy among women with early-stage breast cancer: According to this study, Japanese and Filipino women in Hawaii are much less likely than white women to undergo breast-conserving therapy for early-stage breast cancer. Researchers linked data from the Hawaii Tumor Registry to census and health care claims data and then retrospectively analyzed breast cancer management of 2,030 women (935 Japanese, 144 Chinese, 235 Filipino, 293 Hawaiian, and 423 white women) who were diagnosed with early breast cancer in Hawaii from 1995 to 2001. The researchers note that ethnic differences (e.g., small breast size) and cultural preferences may explain some of the observed differences.

Less effective treatment and lower socioeconomic status may account for disparities in breast cancer survival: Researchers studied more than 35,000 Medicare-insured women with early-stage breast cancer for as long as 11 years and found that black women were more likely than white women to live in the poorest census tract quartiles. Also, more black women (15.7%) received breast-conserving surgery without follow-up radiation therapy than white women (12.4%), Hispanic women (11 percent), and Asian women (7.9 %). Since the recommended therapy for early-stage breast cancer is breast-conserving surgery plus radiation, these treatment differences could have contributed to disparities in survival, suggest the researchers.

Minority women are less likely than white women to receive adjuvant therapies following breast cancer surgery: Women with breast cancer do not consistently receive adjuvant treatments—such as radiotherapy following lumpectomy and chemotherapy for ER-negative tumors—that have been shown to increase survival. However, a survey of surgeons at 6 New York hospitals treating 119 women who did not receive guideline-recommended adjuvant therapy found that minority women were more likely than white women (73% vs. 54%) not to receive adjuvant treatment, as were women who were uninsured or had Medicaid coverage compared with those who had Medicare or private insurance (54% vs. 19%, respectively).

Study finds disparities in receipt of chemotherapy following ovarian cancer surgery: Clinical guidelines have recommended since 1994 that all women diagnosed with ovarian cancer stage IC-IV or higher receive chemotherapy following surgery to remove the cancer. This study of more than 4,000 black and white women aged 65 or older who were diagnosed with stage IC-IV ovarian cancer found that white women were more likely than black women to receive chemotherapy after surgery (65 percent vs. 50 percent, respectively), although survival rates did not differ between the two groups of women. Women with higher socioeconomic status (SES) had increased use of both surgery and chemotherapy, and women in the lowest quartile of SES were more likely to die than those in the highest quartile of SES.

Socioeconomic barriers exist to timely diagnosis and treatment of prostate cancer in black men: Researchers identified 207 black men and 348 white men recently diagnosed with prostate cancer from the North Carolina Cancer Registry. They found that black men were younger and had less education, job status, and income than white men. Although black men and white men had to travel similar distances for health care, black men still had less access to care. They also had poorer health insurance coverage and less continuity of care than white men, used more public clinics and emergency wards, expressed less trust in their physicians, and were more likely to skip physician visits that they felt they needed. The researchers conclude that barriers to early diagnosis and appropriate care for prostate cancer among black men are related more to socioeconomic position than to lack of education or cultural misunderstanding.

Mistrust: The historical mistreatment faced by groups such as African-Americans and Puerto Ricans has resulted in mistrust of research and the medical system, and ultimately, underrepresentation.17,18
Lack of awareness: A national survey of cancer patients found that 85% of respondents were unaware that participating in a clinical trial was an option for them.19
Cultural barriers: Certain cultures’ non-Western views of health and disease may make clinical trials a less desirable option.20
Language/Linguistic differences: Many U.S. clinical trials require English proficiency for potential participants, automatically excluding those who do not speak the language.21
Low literacy: The complexity of consent forms and other clinical trials materials may also be a barrier to those individuals with low literacy.22
Socioeconomic obstacles: Underrepresented populations are more likely to encounter social and economic barriers to participating in clinical trials. Unreliable transportation and living in remote areas may prevent many otherwise eligible patients from participating in clinical trials. Some low income groups have decreased participation due to competing issues such as unpaid work leave and lack of childcare.23
Cost/Lack of insurance: Costs associated with clinical trials are often a concern for potential participants. A study of NCI sponsored cancer treatment trials found that uninsured patients represented only 5.4% of all clinical trial participants.15 Even when participants have insurance coverage, many cannot participate due to high out of pocket expenses not covered by their benefit plan.24
Study design eligibility criteria: Traditional clinical trial eligibility criteria typically limits participation of patients suffering from more than one health condition, which in turn often excludes the elderly, members of racial/ethnic groups, and patients with lower socioeconomic status.25,26
Participants are also often excluded from clinical trials due to characteristics, preferences, and circumstances of the physicians who conduct or refer patients to clinical trials
Lack of minority investigators: 2004 data show that only 12% of all U.S. physicians are African American, Hispanic/Latino, Asian, or Native American. Yet, these minority groups make up more than 30% of the U.S. population.27 Minority patients often choose physicians of their own background, but minority physicians are underrepresented as investigators for clinical trials in the United States. Physicians with access to minority patients could be an important source of racial and ethnic minority trial participants.28,29
Lack of physician referral: Although physician referral is one of the most effective means of recruiting patients to clinical trials, some physicians may be reluctant to refer because they perceive an excessive administrative or financial burden to their practice. Physicians may also hesitate to inform patients of trials based on their own attitudes and beliefs about trials and their assumptions about patient eligibility to enroll according to factors such as age, other existing conditions, cost, or ability to adhere to study protocol. 30, 31
Lack of physician awareness: Primary care and specialty physicians who are not affiliated with research institutions may be less aware of patient eligibility for clinical trials. Lack of awareness is one of the most common reasons physicians fail to refer patients to trials. 32,33
Access: In the access category, significant variation was identified on the dimensions of patient costs and disparities and, to a lesser extent, for the dimension of cost-effectiveness.
Capacity: The propensity of issues related to capacity was relatively stable across the regions, with the exception of the need for better statistics and related data on breast cancer and a country’s infrastructure relative to managing breast cancer.
Research: In the research category, etiology was relatively common across the regions, but significant variance existed in other dimensions such as personalized medicine, need for more locally relevant guidelines (including focus on younger women), participation in international research and better communications.
Advocacy: For advocacy, the quality-of-life and metastasis dimensions were statistically similar across the four regions. Differences were identified for the need to improve, empowerment, increasing attention to survivorship and organization of advocacy nationally.
What can the US learn from smaller, lesser resourced countries that participated in the study?
First, and potentially the most controversial, is “ removing barriers”. This needs to start by providing access to early detection and screening via public and private means, as the cost of cancer if caught early is far lower than if caught in later stages. In some countries, where the populations are not responsive to or are fearful of public screening, or where the cost of large scale public screening efforts would be prohibitive in cost or may not be best use of limited resources, a far more effective approach is ”mother-sister-daughter” or “father-brother-son” screenings. (Once one person is identified as having cancer, he/she would be encouraged to bring in or suggest immediate relatives be screened for similar risk.) In France, all cancer screening is free to all citizens and public health care workers are measured on their achievement of assigned populations to be screened. In Taiwan, one of the few Asian countries where the incidence of breast cancer morbidity is among the lowest in the world, all 12 year old girls are taught breast care and early detection in public school.
Removing barriers also means ensuring that health insurance and providers ensure all patients have access to cancer diagnosis, therapy and care as established by national guidelines. In Singapore, one of the most highly rated and cost effective health care systems in the world, health insurance is an elegantly simple and cost-effective system: each person is required to put a minimum percentage of one’s income into a tax deferred medical fund. A small percentage of that fund is allocated to help the government pay for the uninsured. The balance, like any money market fund or CD, accrues interest. When needed, it can be drawn upon for any health care expense. Should a person run out of funds, other family members may contribute from their funds. And most countries, when a person who is not a legal resident and is not insured presents with cancer or other serious condition, will immediately assist that individual to return to their home countries where national health or other insurance and care is provided to its citizens.
In short, US may look to other countries – even ones as small as Singapore – for creative solutions to reduce, not increase, the cost of quality cancer care.
