Myeloma Is Different in African Americans

Like many patients who are diagnosed with the disease, you may have never heard of multiple myeloma. Here are some key facts about how myeloma affects African Americans:

  • African Americans have an average earlier age of onset of myeloma1.
     
  • The pre-myeloma condition, monoclonal gammopathy of undetermined significance (MGUS),  is more common in African Americans. Studies in Africa have also shown this increased incidence2.

The IMF is educating the multiple myeloma community to ensure that African Americans can be diagnosed earlier. Earlier diagnoses are linked to better outcomes.

African Americans are twice likely to get myeloma

Wait: Now What’s That Good News Again?

Some evidence suggests the biology of myeloma may be different in African Americans when compared to white Americans.Genetic studies are ongoing to better understand how myeloma may be different in African Americans. We do know, for example, that when African-American patients are in clinical trials, they fare as well as white patients.5

African Americans and Multiple Myeloma Treatments

We know that African Americans tend to have a better prognosis with multiple myeloma. Yet, other patient populations have greater improvement in survival rates than the African-American population.6

The medical community and the African-American community are working together to understand why this is happening. We do know that longer survival is a result of

Unfortunately, many African-American patients may not be presented with these care options.6 The IMF believes patients of all races and ethnicities should have knowledge of the best treatment options available.

 

African Americans and Access to Clinical Trials

Disparities in Clinical Trials provided by www.census.gov

While African Americans make up 20% of the people living with myeloma in the U.S., they only account for 6% of all patients in clinical trials.7. Experts say this disparity exists for the following reasons:8-10

Healthcare-Provider Factors

  • Unwillingness to refer patients for trials
  • Fear that clinical trials create a financial or administrative burden to the practice
  • Lack of clinical trial availability
  • Few minority investigators
  • Lack of knowledge
  • Cultural differences


Patient-Related Factors

  • Mistrust of the medical or research systems
  • Perceived risk of harm
  • Cost
  • Comorbidities
  • Lack of transportation
  • Lack of education about clinical trials
  • Time commitment and conflicts 
  • Fear of clinical procedures
  • Family issues


How can these treatment disparities be overcome? First, the IMF encourages health-care providers and patients to learn about clinical trials that provide new drugs and new approaches to care. You can do so by visiting the Myeloma Matrix 2.0 Smart Search.
 
Secondly, as we know, there are few clinical investigators who are minorities.11 Perhaps this may affect the comfort level in patient/doctor or patient/nurse relationships. For that reason, we encourage collaboration among many health-care professionals. As reported by Kaiser Health News, black pharmacists in the U.S. are helping to close the cultural gap.12

We encourage you to involve your whole health-care team in your care plan.

Before new drugs or procedures can be approved for use in multiple myeloma, clinical trials must prove that they are safe and more effective than currently available options. Use the Myeloma Matrix 2.0 Smart Search tool to find multiple myeloma clinical trials
