A year ago, we joined fans cheering for Evan Lallo as he celebrated clean scans after treatment for Ewing sarcoma with a ceremonial first pitch. Today, he’s back on the mound, a reminder of how far he’s come and the message that carried him through: “Just keep going!”
Evan’s cancer journey began in summer 2024, when he started having pain in his right shoulder. Active in athletics, his first diagnosis was rotator cuff tendinitis. He started treatment, but the pain and function of his right arm worsened. An MRI ultimately showed a mass on his neck, and further testing revealed Ewing sarcoma.
Evan began treatment the next day. This involved multiple rounds of chemotherapy and radiation therapy.
“Evan responded very well to treatment. The tumor kept shrinking, but he was still struggling with his arm function,” says Evan’s pediatric oncologist Dr. Matteo Trucco.
“We were watching Evan closely to see if treating the cancer would take the pressure off his nerves and allow them to heal on their own. Fortunately, he regained a significant amount of function in his bicep. However, he didn’t recover much movement in his shoulder, which affected his ability to lift his arm up,” says peripheral nerve neurosurgeon Dr. Megan Jack.
To improve his shoulder mobility, Dr. Jack opted to do what’s called a nerve transfer, which involves taking a healthy nerve and connecting it to the damaged nerve. Dr. Jack says the healing process takes time and must be paired with physical therapy. Evan’s shoulder continues showing signs of improvement.
By June 2025, his scans showed no signs of cancer remaining. Evan celebrated his last day of chemo and rang the Bravery Bell, surrounded by his care team, friends and family. Funds to support the occasion came from one of our Catalyst Grants aimed at personalizing experiences for patients.
Evan spent the past school year playing three sports and is excited to begin high school this fall.
“I stayed focused on what needed to be done so I could get back to doing the things I love,” says Evan.
