Date sent: Thu 3/18/04Things we've learned about brain Oligos and brain tumors This was written to someone that found
this website and had a lot of questions - About the path and the genetics: Astrocytes, oligodendrocytes and
microglia are the three types of glial
cells in the brain. Astrocytes
become astrocytomas, oligodendrocytes become
oligodendrogliomas. These
cells can be mixed in a tumor referred to as oligoastrocytomas.
Typically pure astrocytomas are more aggressive then
oligodendrogliomas and can evolve into glioblastoma
multiforme – the most aggressive
type. Oligodendrogliomas
are typically more slow growing,
always recur, and recur in a more aggressive form with each
recurrence. Mixed
oligoastrocytomas take on the properties of the more dominant
cell type, which is why your doc is waiting for that
information. The genetics tests that I know about are
1p and 19q, 10q, EGFR, PTEN.
The 1p and 19q are very indicative of prognosis.
The better prognosis occurs with a tumor that HAS 1p
and 19q DELETION. Those
tumors tend to be more responsive to chemotherapy. 10q is also
being used as a predictor but is not as well documented as 1p
and 19q. EGFR and
PTEN are cell receptors, and having the receptor is better (I
think) so that additional chemo can be used. Older chemo is called PCV,
new chemo is Temodar (Temozolamide)
and has a great record of extending the time to progression. About family and help: We have had tremendous help and community support, neither of us has family near by. Some tactics to make use of these resources have included:
(from Dan) “Having a brain tumor or injury is a total change in one’s life, and letting go of who I have been has been is the most difficult part for me, and I suspect will be the most difficult part for him. A man’s identity is so tied to his ability to DO things, like working, driving, being the provider. This transformation is very hard to fathom or accept or even live with. It has taken years for me to even acknowledge or see. He is going to need a lot of support and
patience from his community and family through this process.
There is a lot of grief and loss.
It’s like a part of him dying in a very slow and in
an agonizing way. And
the worst part about it, as I alluded to before, is that he
powerless to do anything about it.” With love and blessings, Copyright March, 2004 - Please do not copy any part of this journal without written permission. |
