Single dose vs fractionated
« on: March 19, 2013, 09:47:51 am »
Thank you for all of your replies regarding radiation treatment.  I have finally decided on proton therapy for my AN.  Next choice is single dose or fractionated radiation.  Please tell me which is better in terms of killing the tumor and the safest health wise.
Thanks

I looked over your previous posts and all you say is that you have a 2cm tumor.

You don't reveal any of your age, symptoms, hearing issues, all the dimensions and location and all of those variables go into helping you evaluate your choices.

Anyway, we can't tell you what's better for you.

All any of us can tell you is why we chose what we chose.

I chose single session Gamma Knife for the following reasons:

1 - I'm 66 and there was no way I was having my head cut open if I could help it.
2 - My hearing on the AN side was totally gone so there was nothing to save.
3 - I was still going to have balance issues no matter what. Although I have had some modest improvement there, even before the GK.
4 - I read that GK was accurate down to about 1mm and my tumor was 4mm x 4mm by 12mm. Small enough to require pinpoint accuracy.
5 - One time treatment. In and out same day. Stick a fork in it, it's done.

3/15/18 12mm x 6mm x5mm
9/21/16 12mm x 7mm x 5mm
3/23/15 12mm x 5.5mm x 4mm
3/13/14 12mm x 6mm x 4mm
8/1/13 14mm x 5mm x 4mm (Expected)
1/22/13 12mm x 3mm (Gamma Knife)
10/10/12 11mm x 4mm x 5mm
4/4/12 9mm x 4mm x 3mm (Diagnosis)

I know Proton Therapy sounds good in theory.
Worth doing more research, particularly around range uncertainty, minimum diameter beam sizes, image guidance, overall accuracy and most importantly actual results.

Some nice articles to get you started

10x5x5mm AN
Sudden Partial hearing loss 5/28/10
Diagnosed 7/4/10
CK 7/27/10
2/21/11 Swelling 13x6x7mm
10/16/11 Hearing returned, balance improved. Feel totally back to normal most days
3/1/12 Sudden Hearing loss, steroids, hearing back.
9/16/13 Life is just like before my AN. ALL Good!
