I think my CK story is quite positive, but it is probably too early to say that definitively, since I am not quite 1 year out of treatment.
I have a 2.5 cm tumor, which is on the larger side for radiation. My hearing has been preserved. I have dealt with intermittent post-treatment symptoms, such as balance issues, which I describe in more detail in my website below (see the post-treatment section). I am sure the symptoms relate to post-treatment swelling and will recede with time.
As to the GK/CK debate, I agree with Steve that they are essentially the same in terms of tumor control, but CK is less likely to damage the surrounding nerves and therefore preserve your hearing. If you have some hearing you want to preserve, CK is probably worth looking in O
n the insurance front, I was in an HMO where GK was available in "network" but CK was not. During the appeals process (which Stanford handled for me), I submitted a personal letter arguing that the difference in hearing preservation results made CK "medically necessary" in my case. The appeal was successful and the HMO was forced to cover the treatment.
Good luck and be well,
Francesco
