WASHINGTON, April 28, 2011 /PRNewswire/ -- With minorities expected to become the collective majority in the US by 2050, a report released today by the President's Cancer Panel identifies an urgent need to expand research and improve understanding of the factors that influence cancer risk and outcomes among diverse populations. The Panel's report, America's Demographic and Cultural Transformation: Implications for Cancer, states that knowledge of cancer risk, incidence, progression, and outcomes is based largely on studies of non-Hispanic white populations.  Therefore, the current understanding of risk factors, screening guidelines, and treatment may not be appropriate for individuals of non-European descent.  The Panel also calls for higher standards of "cultural competence" among healthcare professionals to better address cultural and language barriers that can negatively impact the quality of patient care.

"As the cultural landscape of our nation continues its transformation, the one-size-fits-all approach to cancer screening guidelines, prevention, and treatment is no longer appropriate," said LaSalle D. Leffall, Jr., M.D., chair of the Panel. "A more accurate understanding of cancer risk factors among diverse populations and improved training in cultural competency are critical steps toward reducing the national burden of cancer."

With cancer incidence among minority populations projected to nearly double between 2010 and 2030, the Panel calls for a more accurate assessment of the effects that a changing demographic will continue to have on cancer incidence and mortality in the coming decades.

Key Findings and Recommendations

• While the impacts of socioeconomic and sociocultural determinants of health outcomes have long been recognized, cancer research has focused primarily on using genetics to identify health differences.  The Panel recommends that both biologic and sociologic factors be examined to truly understand diverse populations and resulting health disparities.

• The Panel identifies a need to evaluate current cancer screening guidelines to determine their accuracy in assessing disease burden in diverse populations.  In particular, the report recommends that researchers consider the patient population in its entirety and identify common genetic, sociologic, and environmental risk factors on which to base screening recommendations.

• Researchers must examine the impact of changing demographics and expand the current understanding of related factors that influence cancer risk, incidence, and mortality.  This knowledge must then be applied for the benefit of all subpopulations so that more accurate preventive measures can be implemented. 

• The majority of health care providers do not adequately consider patient sociocultural and socioeconomic characteristics when addressing cancer prevention and treatment, even though these factors can have independent and sometimes profound effects on cancer susceptibility and outcomes in both native and foreign-born Americans.  In addition, the Panel found that patient-provider language differences are a significant barrier to the provision of quality health care.  The Panel recommends that cultural competency become an integral part of medical and research training curricula, as well as a continuing education requirement.  The Panel also recommends that trained interpreters be viewed as essential members of the health care team.

• Though personalized medicine for all is the ultimate goal in cancer care, it is not universally feasible or affordable in the near future.  The Panel concludes that research is needed now to identify subpopulations at high risk of disease due to genetic/ancestral, biologic, sociocultural, and other factors that directly relate to risk or response to therapy.  

• Weaknesses in existing vital statistics, census, public and private insurer, and cancer surveillance data may thwart efforts to characterize populations in a scientifically meaningful way.  To address these serious data deficiencies, the Panel calls for improvements in data collection, as well as standardized data sets and definitions of race and ethnicity.  

• There is a need for improved data sharing among government agencies at all levels as well as a need to address issues of data compatibility.

• Additional recommendations include increasing the diversity of the cancer research and care workforces; exploring and evaluating the benefit of patient navigation models; and continuing basic, translational, clinical, population, and dissemination research on cancer health disparities.

The Panel concludes that cancer and other health disparities will be eliminated only when the social determinants of poor health outcomes, such as poverty, low educational attainment, substandard housing and neighborhoods, and insufficient access to quality health care, are adequately addressed.

The President's Cancer Panel (http://pcp.cancer.gov) consists of three members appointed by the President.  Current members include LaSalle D. Leffall, Jr., M.D., F.A.C.S., Howard University; and Margaret L. Kripke, Ph.D., University of Texas MD Anderson Cancer Center.  The Panel, established by the National Cancer Act of 1971, is an independent entity charged with monitoring the National Cancer Program and reporting annually to the President on any barriers to its execution.  While the Panel receives logistical and staff support from the National Cancer Institute, the Panel is not advisory to the NCI.  The Panel does not conduct scientific research and its conclusions and recommendations should not be inferred as policy or perspectives of the NCI.   Contact: Katherine Nicol, 202-706-7405,  [email protected].
