DALLAS (CBSDFW.COM) – In December, CBS 11 reported about 7-year-old Zach Guillot, a Dallas first-grader who is undergoing chemotherapy for a rare form of leukemia.

He was diagnosed with the disease two-and-half years ago and has already undergone a bone marrow transplant. His younger brother, Jake, generously donated it to him.

That worked briefly, but the cancer returned in the days leading up to Thanksgiving. He now needs a donor outside the family to step forward.

In our original story, Dr. Victor Aquino called the need for another donor a “life or death matter.”

Doctors say the boy may not be able to survive another relapse, should symptoms return.

Well, each year the Yavneh Academy, an Orthodox Jewish high school in North Dallas, teams with Carter Bloodcare to host a blood drive. This year, the drive will be in Zach’s honor.

The event is Monday Jan. 16 from 12:30 p.m. to 5 p.m. at 12324 Merit Drive in Dallas. For those who wish to schedule an appointment, call 972.839.6916 or email

Last year, the drive was held for Madalyn White, the granddaughter of the man who handles the academy’s printing needs. The 11-year-old was diagnosed with a rare disease called TTP, or Thrombotic Thrombocytopenic Purpura.

In the announcement of this year’s blood drive, academy spokeswoman Deb Silverthorn reported Maddie is “doing well and in smilingly good manner!”

Zach and Maddie, as it turns out, are schoolmates.
