With all of the pathology and scan results, we have a final verdict:
Stage 4 Neuroblastoma in the Abdomen
There are NO neuroblastoma cells in his bone marrow, bones, liver, or soft tissue... Hooray! These are all areas that neuroblastoma spreads to, and Case has specific tests and scans for each of these areas.
It is Stage 4 because, aside from the large tumor in his abdomen, there is a tiny little tumor deep in his chest in between his spine and lung (though it does not go into either of these areas). The Stage 4 classification over Stage 3 doesn't devastate us because he receives the same treatment either way. Dr. Pass felt like it isn't a true metastasized tumor, but a secondary piece from the original (or something like that).
So we are looking at 8 cycles of chemo, approximately 3 weeks each. There you have it.
