A Thursday evening stem cell swab event aimed at finding a match for an eight-year-old Edmonton boy with leukemia was so successful, it ran out of kits.

Brady Mishio has acute myeloid leukemia, a cancer of the blood, and has undergone three rounds of chemotherapy since being diagnosed in November 2016. Doctors say he needs a bone marrow transplant in order to live.

The transplant needs to come from someone who is a match to Brady’s stem cells. “What Canadian Blood Services tells, and told me from the beginning, is that the odds are about 50/50 that Brady will find a match,” said his father, Terry Mishio.

Matches are made via the Canadian Blood Services (CBS) OneMatch stem cell and marrow network. It’s a database that pairs volunteer donors to patients who require stem cell transplants.

According to CBS, donors and patients are matched according to the compatibility of inherited genetic markers called “human leukocyte antigens.” A perfect stem cell match can be difficult to find, which is why the push is on to get more people registered.

“The more people that are in this bank — and they check it every 24 hours — the more chances that he or some other Edmontonian kids are going to find that match,” Mishio said.

Joining the bank is quick, simple and non-invasive: the potential donor just fills out some paperwork and swabs the inside of their mouth with a buccal swab (similar to a Q-Tip.)

A massive swabbing event to potential stem cell donors took place Thursday evening at the Holy Cross Ukrainian Catholic Parish in north Edmonton. Mishio is on leave from his job as a recruiter with the Edmonton Police Service, and several of his policing coworkers were expected to come out in support.

Organizers expected a big turnout, but the response was even greater than they hoped for.

The event was scheduled from 4 p.m. to 8 p.m., but 100 people showed up before the doors were set to open. Mishio’s co-worker Trishia Comeau said by 7 p.m., 1,100 people had been swabbed and Canadian Blood Services had used up all of the swabbing kits in Edmonton.

“Thanks people of Edmonton for helping, we are going to keep this momentum going,” Comeau said early Friday morning.
