Hi Diane,
Please keep in mind, that with the measurements you are noting, there is usually a margin of error of +/-2mm, so it sounds like the tumor is still within the same size... so, I (personally) would not worry about that. After some time, the AN may shrink in size, but the true goal (IMO) of the radio-treatment is the necrosis (tumor death of the turmor's DNA). As you know, the residual remains of the tumor will be there down the road, but it will be dead. I know of some that their AN's did shrink a bit...so.... let's see what happens.
Now that Jim is 10-11 mos post treat, I have to share the same limb with the rest here that have posted... 'non-enhancement' (if it looks dark) within the body sure sounds to me like they hit the core of the AN and it's starting to suffer the necrosis! (YAY!) The rest of the report, as you note, sounds right on track. Please give Jim a congrats to me and pls keep us updated on what his doc says after viewing the films.
Sounds like all is going great! congrats!
Phyl
