Line 40:

Patients diagnosed with a medulloblastoma or PNET are 50 times more likely to die than a matched member of the general population. The 5-year relative survival estimates (based on data from 2001–2006) are 64% in children (1–9 years), 35% in adults (20–25 years), and two known survivors over the age of 25 (Brian Fitzpatrick) aged 34 in 2002. In 2007 a PNET was discovered in the oldest known patient(Tim Young 41 years of age) in Atlanta wrapped around the spinal cord in the C4 cervical area for the first time. A sample was removed by Neurosurgeon Dr David Disch, and the spinal cord was compromised to avoid the tumor from entering the spinal fluids. The procedure caused right side hemiparesis but no other effects. Oncologist Dr Ron Steis(Atlanta Cancer Care) and a global team administered 15 rounds of 5 types of chemo, followed up by 8 weeks of trilogy radiation, and 22 additional rounds of chemo until the patient was cleared. As of March 2014 Mr Young is still the oldest known survivor of PNET.

Oncologists, Dr. Thomas Leavitt and Dr. Lyn Soe (Cameron Park Oncology, Cameron Park CA) treated Tamara H. Ruiz for PNET. Following major surgery and official diagnosis in April 1997, a rigorous protocol which included 5 types of chemo, radiation as well as additional rounds of chemo was initiated. The patient was 47 years of age at the time of diagnosis. {{As of|2014| September}} 2014 Tamara H. Ruiz currently age 65, is currently free of disease and appears to be the oldest known survivor of PNET.
