Hapa Student Is Looking for a Marrow Match


Chris Ishida, who is half Japanese and half Caucasian, is looking for a bone marrow match. It is difficult for patients who have multiple ethnic backgrounds to find a match.




Chris Ishida, a 19-year-old freshman at Pitzer College in Claremont, has been looking for a bone marrow match since last December.

The Glenview, Il., native was suddenly diagnosed with severe aplastic anemia, which requires a bone marrow transplant. According to the National Marrow Donor Program, SAA is a disease that develops when the bone marrow stops making enough red blood cells, white cells, and platelets for the body. People with SAA are at risk for life-threatening infections or bleeding.

Finding a marrow match is determined by a combination of human leukocyte antigen (HLA) typing inherited from each parent. Therefore, if a given patient doesn’t find a match among siblings, the next best chance to find a match is among people who share the same racial or ethnic heritage.

Since there were no matches among his family, Ishida, born hapa, has the best chance to find a match from donors who are also half Japanese and half Caucasian.

About 8 million people have registered on the Be the Match Registry; 74 percent of those are Caucasians, 10 percent are Hispanics/Latinos, 7 percent are Asians, 7 percent are African Americans, and only 3 percent have multiple ethnic backgrounds like Ishida.

“We could dramatically impact the survival of many patients in serious need of a bone marrow transplant,” remarked Masuo Ishida, Chris’ father, in reference to the marrow registry. The Ishida family is urging more members of the public to become donors.
