My son is 3 1/2 years old and had just been diagnosed with medulloblastoma. He had surgery to have the tumor removed but he also has spots on his spine. The doctors say he has a very aggressisve form of medulloblastoma and prognosis is poor. Trying to figure out which option would be best for tx. He can do the standard tx with chemo and radiation. This impairs cognition greatly. We could do the stem cell/bome marrow tx which is a newer tx with high levels of chemo. It sounds like the radiation has a slightly better chance but so many side affects. Anyone have any ideas?
