AJ had 30 doses of radiation along with 40 weeks of chemotherapy beginning June 10, 2021.
By August, doctors had seen the tumor shrink by 50 percent. By Jan. 2022, doctors said the tumor had shrunk even more and that there were no traces of metastatic cancer.
On March 25, AJ got to ring a ceremonial bell marking the end of his cancer treatments.
"We had a five-year plan because the survival rate for Rhabdomyosarcoma is five years," Tricia said. "So off we were, trying to get ready to start life over again. He did 25 weeks of [physical therapy] to get stronger, he was eating, gained all his weight back, he was playing basketball, playing baseball, out with his friends, enjoying life."
On June 21, AJ was awarded a $5,000 college scholarship from Flyers Charities through Michael's Way, a charity that helps support families dealing with pediatric cancer. He was majoring in communications/marketing at Penn State Brandywine.
John Tortorella, who had been hired as Flyers coach days earlier, surprised the award recipients with their scholarships on a video call.
Not long after, though, scans showed AJ's cancer had returned, and this time the tumor was in his pancreas.
The Flyers learned of AJ's cancer returning and Flyers Charities executive director Cindy Stutman said she and her staff did their best to stay in contact with the family.
"It's heartbreaking," Stutman said. "We have just given this young kid a scholarship who was going to start college. So, 'Torts' and Travis Konecny both sent AJ videos just to let him know we were thinking about him, continue to fight, we're all behind him. We sent him a team-signed jersey just to try to lift his spirits."
After a family vacation to San Diego, AJ restarted his treatments. Then on Sept. 6 a tumor on AJ's spinal cord left him paralyzed.
Doctors told the family that radiation possibly could shrink the tumor and allow AJ to walk again, but there was no guarantee it would work.
Instead, he entered hospice care and spent his final weeks watching television with his family and friends.
He also would talk about the Flyers with Cody, who is a year younger. AJ had bought a half-season ticket package for Flyers games last season, and the brothers would go to games together when AJ felt healthy enough.
