FRANKLIN, Pa. (EYT) — An online fundraiser has been established to help the family of a 4-year-old boy who was recently diagnosed with a stage three, high-risk neuroblastoma.

Jill Shull, of Franklin, established the fundraiser on gofundme.com to support her 4-year-old nephew, Andrew O’Neil, and his family.

Andrew, son of Jaime Hagerty O’Neil and Brian O’Neil, of Pittsburgh, was taken to the Emergency Room at Children’s Hospital of Pittsburgh on April 15, 2015, for ongoing symptoms that had progressively worsened.

Andrew’s family was informed that night that he had a large tumor on his kidney.

Initially, Andrew’s parents were told that he had a Wilm’s tumor on his kidney and that he was going to have surgery the next day to remove his entire kidney and the tumor.

Later that evening, his family was informed that surgery was cancelled, and there were thoughts that the tumor might be much more involved than just a Wilm’s tumor. After surgical biopsy of the tumor and bone marrow along with many other nuclear tests and scans, it was determined that Andrew had a stage three, high-risk, neuroblastoma that was not operable at the present time.

“This was not the news that Andrew’s parents were hoping for because it meant that he would undergo a very, very aggressive treatment plan,” said Shull in an update on the fundraiser’s webpage.

Andrew’s projected treatment plan will include six rounds of inpatient chemotherapy to shrink the tumor, a major surgery, stem cell harvesting and transplant therapy, radiation, and maintenance retinoid therapy and immunotherapy.

It is estimated that his entire treatment program will take one and a half years to complete.

Andrew began his first round of chemotherapy on April 24.

“This Go Fund Me pledge is being made to help Andrew and his family be able to fight this battle with less financial burden and hardship as the costs that will be incurred with frequent hospitalizations, chemotherapy, radiation, and stem cell therapy will be astronomical,” said Shull. “It will likely mean extended periods of time off of work for one or both parents and possibly even one of them needing to stay home regularly (both parents currently work full-time) to care for Andrew through this difficult time in their lives.”

At this time, the fundraiser has raised more than $22,000.00 to support Andrew and his family.
