Bruce:
Thanks for your comments. Informative, as always.
I read the report by Dr. Sheehan regarding the success of radiation treatment on small (under 3cm) AN's. Although I don't pretend to be in his league, medically speaking, I do tend to agree with his conclusions - and the single (positive) response that was offered. Had I had the option of radiation-only treatment, I'm pretty certain I would have taken that route, rather than microsurgery. I say this as person who had a very good outcome from microsurgery.
Actually, my neurosurgeon follows a slightly different path for large tumors, such as I had (4.5 cm). He resects as much of the tumor as he can - using nerve monitoring to avoid nerve damage - and then, attacks whatever remains with fractionalized radiation treatments. He works with a radiation oncologist to determine the exact path, duration and intensity of the radiation. I completed my 26-day radiation treatment regimen on October 16th - and had no ill effects. I'll have a 'fresh' MRI in a few days (12/1) to be used as a baseline for future MRI observations. Both my neurosurgeon and radiation oncolgist are extremely enthusiastic about this treatment (microsurgery/radiation), claim it has an almost-100% success rate (no tumor re-growth) and believe that I will be another success story. Based on the apparent loss of almost all my previous AN symptoms so far, I can happily agree with their assessment.
In any case, while there are many approaches to AN treatment, it appears that radiation is a very viable treatment for under-3cm tumors. With the information now available regarding radiation treatment for AN tumors, I would assume that any potential microsurgery patient with a 'small' AN would explore and seriously consider the radiation approach. I would.
