On June 9, 2011, after 2 weeks of unexplained headaches, nausea, and vomiting, an MRI revealed a mass in Eric's brain. Eric endured his 1st brain surgery on June 14, 2011. It was after this surgery that we were informed that Eric had brain cancer, specifically a grade 3 Anaplastic Ependymoma. Eric went on to receive 6 weeks of Proton therapy (a form of radiation therapy) at CHOP. The post radiation MRI revealed a healthy, "normal" brain. Unfortunately, our relief was short lived. In April 2012, a routine MRI revealed a recurrence of disease. We had decided at this point that it was time to turn to a hospital that strictly dealt with cancer. Eric began a chemotherapy clinical trial at Memorial Sloan Kettering Cancer Center in NYC shortly after this recurrence. He began with a clinical chemotherapy trial to try and shrink the tumor, this failed. Eric underwent his 2nd brain surgery 2 weeks before his 13th birthday. After surgery he had another 6 weeks of standard radiation to his brain. Three months later a post radiation scan revealed another recurrence in a different area of his brain. In October of 2012 Eric had his 3rd brain surgery. This surgery was done to remove the new tumor and also to place an Ommaya reservoir, a special port placed in the brain, which would be used to inject a special radiological antibody into Eric's cerebral spinal fluid. This was also a new clinical trial. In late January we found that Eric's disease had again recurred. Again Eric underwent more radiation with no change. He went on to join 3 more clinical trials in the hopes that one of these would finally kill the relentless disease. On December 23, 2013, Eric finally became cancer free when he gained his wings at 8:29 p.m.
