Meet Caryn Hsu.

She’s a wife, a daughter, a current USC graduate student, and an active Tzu Chi volunteer. She’s also just 32 years old.

This year, Caryn received life-changing news. She has B-Cell MLL-Rearranged Acute Lymphoblastic Leukemia with an unfavorable chromosome mutation. It is a very rare and aggressive form of leukemia (especially given her age) that leaves Caryn with a cure rate of just 10% with chemotherapy alone.

Within a week of being diagnosed at the ER, she was hospitalized and immediately put on her first round chemotherapy to destroy overproducing white blood cells. Unfortunately, chemotherapy also kills healthy red blood cells. To counteract this, Caryn has been receiving blood transfusions to replenish her red blood cell supply. As of March 2, she’s received a total of 6 chemotherapy treatments so far.

In order for her body to produce any healthy white blood cells, Caryn needs a blood stem cell transplant.

With a transplant, her chances of recovery significantly increase to 70%. Her doctors at City of Hope are currently searching the global donation database registry called Be the Match, but so far no match has been found as there is a shortage of registered donors from ethnic minorities that are suitable for Caryn. This is why we need your help. 

To diversify the registry and help save more lives, we’re calling on people ages 18-40* (and particularly of Asian heritage) to sign up as potential donors of peripheral blood stem cells (PBSC) and bone marrow.
Joining the registry does not guarantee that you will be matched with someone, and you still reserve the right to decline if a match is made in the future.
