The query got here at dinner towards the top of June.
Anesthesiologist Nick Mondek, 48, was dying of acute myeloid leukemia, a most cancers that impacts blood-forming cells within the bone marrow. It was a critical subject to deal with together with his then-9-year-old son, Stephen, as they ate bowls of pasta.
However Mondek wanted a stem cell donor — and quick. So he requested his son to save lots of his life.
The teenager agreed to be examined at Cedars-Sinai Medical Heart to see if he might donate stem cells to his father.
The Rolling Hills Nation Day fourth-grader, who goals of changing into a physician for a Main League Baseball workforce, had his personal query first: “When will we go?”
In July, Stephen turned what Cedars-Sinai Medical Heart believes is its youngest recognized stem cell donor.
“I simply wished to assist,” Stephen stated.
His donation doesn’t simply purchase his father time however presents hope that Stephen’s stem cells will construct a more moderen, stronger immune system that can assist his father combat off blood most cancers.
“I wished him to do that as his personal determination,” Mondek stated. “I didn’t need him to really feel compelled. I didn’t need him to really feel like he needed to do it.”

Mondek’s journey from physician to affected person started in April 2022.
The then-45-year-old, an worker on the Martin Luther King Jr. Ambulatory Surgical procedure Heart, felt continuously fatigued with little urge for food. Then someday he couldn’t flip his head. His resting coronary heart fee jumped from a typical 60 beats per minute to a regarding, racing 100 bpm.
“Being a typical cussed doctor, I simply stored writing it off,” he stated. “I’d take antibiotics, I’d take ibuprofen, pondering it’s this, pondering it’s that, not even entertaining the truth that it may very well be most cancers and even leukemia.”
Weeks of unrelenting signs led Mondek to take a easy Full Blood Depend, or CBC, check. He was hospitalized inside hours of receiving the outcomes.
Mondek first discovered support in his brother, whose stem cell donation despatched Mondek’s blood most cancers into remission.
In April, nevertheless, the leukemia returned.
“We adopted each scientific protocol, however the illness nonetheless managed to return again, so we had a brand new drawback on our fingers,” Dr. Ronald Paquette, scientific director of the Stem Cell and Bone Marrow Transplant Program at Cedars-Sinai Most cancers, stated in a information launch. “How might we deal with his most cancers a second time round and have a greater likelihood that it doesn’t return?”
Paquette and Mondek looked for genetic matches however discovered none in his household or within the Nationwide Bone Marrow Registry.

That’s when Mondek opted for a curveball.
He recalled a good friend efficiently fought lymphoma after receiving a stem cell transplant from his 18-year-old son.
Paquette confirmed that Stephen, who turned 10 final month, was a risk. Stephen was mechanically a partial match since kids obtain half their DNA from every of their mother and father.
Additional testing revealed that Stephen’s immune system was suitable together with his father’s.
Mondek’s subsequent dialog together with his son was much more difficult than the preliminary lifesaving ask. He needed to clarify the ins and outs of the taxing preparation and process.

“Daily, I inform sufferers in regards to the dangers and advantages earlier than their procedures,” Mondek stated. “And clearly they’re over 18 they usually’re adults, to allow them to perceive the professionals and cons. So it’s like, how do I discuss to a 9-year-old?”
Mondek defined to his son that there can be a number of weeks of pre-donation prep that included photographs and blood exams. Though his son had reservations, he wasn’t involved about anesthesia or procedures. He did have one fear.
“I didn’t wish to miss any time taking part in baseball,” stated Stephen, a Chicago Cubs fan and a catcher on the Rolling Hills Little League baseball workforce.
There have been, nevertheless, particular concerns due to Stephen’s age. A standard stem cell donation, as an illustration, is mostly a non-surgical process through which blood is extracted from an arm via an IV.
Since Stephen’s veins are considerably smaller than an grownup’s, medical doctors needed to discover one other entry level.
Stephen arrived the day of his process at 7 a.m. He was positioned in pediatric ICU, given common anesthesia, intubated and placed on a ventilator earlier than a central line (catheter) was inserted into his neck, in keeping with his father.
Stephen was then extubated and woken up, after which he rested for an hour earlier than his blood was drained and spun via a centrifuge for six hours to separate out the stem cells.
“A donation from a toddler this younger may be very uncommon,” important care pediatrician Dr. Hoyoung Chung stated. “Stephen was very courageous, and our workforce made positive the whole lot went completely in order that this younger boy might assist his father.”
Stephen went dwelling that very same day to his father, mom Danielle Boyer, and his youthful brother, John.
His father’s restoration was not practically as fast.
Mondek was admitted on July 23 and spent six days at Cedars receiving chemotherapy to suppress his immune system, making it much less prone to reject Stephen’s cells.
Mondek handed a further two weeks within the hospital to guard his fledgling and weak immune system.
Paquette advised Mondek that though the surgical procedure was profitable, it might take greater than a 12 months to find out if his new immune system, powered by his son’s cells, might defeat the leukemia. For now, he’d simply have to attend.
On Aug. 16, Mondek was lastly discharged from the hospital.
He drove straight to Stephen’s baseball recreation to catch his son’s ultimate inning.
