Some thoughts.
Continuing advances in the technology leads to confusion for patients whether Brand A is better than Brand B or Brand C.
If Brand A and B are equivilent in results, please recommend those machines and treat us with that.
Do not recommend a 15 year old Brand C, designed for general purpose radiotherapy, that is in your hospital
If you want more AN patients to be treated by RS, please give us the best options so we can speak positively about the experience.
Single Fraction, multifraction, Radiotherapy over 30 fractions.
Dosage differences, isodose line differences.
Maybe all radiosurgeons should get together, look at how every machine works, and provide an overall rating for each machine, depending on the tumor size.
A survey on dosages and Isodose lines, Iso centres (if applicable) for each machine.
What is the concensus on Best Practice by radiosurgeons for the treatment of AN... I would love to know and maybe they would too...
Some possible survey questions.
Example (to be done for all tumour sizes and each machine type)
For IAC AN's
Hearing Preservation
Facial Nerve preservation
Damage to surrounding tissue/nerves/blood vessels/brain stem
Avoidance of critical structures brainstem, cochlear, optic nerve
Patient discomfort/side effects
Overall total radiation dosage to patient. (increase cancer risk), which machines give maximum radiation to the tumor, and the least to elsewhere)
Real World Machine accuracy. (not mecahnical accuracy)
We probably only want to be treated by the top few machines, with a radiation dose that provides 95%+ cure rate, with the least side effects, and the lowest total radiation dose to the rest of our head and other critical structures.
Should the ANA do a survey of Radiosurgeons for their preferred options?
Watch and Wait versus Microsurgery versus Radiotherapy/surgery.
What is the best management practice for AN? Too much conflicting information here.
All three methods have their place, and I would argue that each method is the best depending on your AN, your age, and your symptoms.
Most medical literature focusses on treating the tumour, hearing preservation, facial nerve function etc.
I think there needs to be further studies on the ongoing psychological effects of an AN.
While around 70% of AN's can remain untreated in peoples heads, the symptoms of AN can be very wearing.
Are we psychologically better off, having small symptomatic AN's treated with Radiosurgery early? especially for patients younger than say 60?
While we look at the physical risks of early intervention for AN, I believe further work needs to be done on the long term untreated psychological effects of AN.
Early radiosurgical treatment of small symptomatic AN's may provide significant long term psychological benefits to the recipient, which may outweigh the physical downside.
I had my AN treated with Cyberknife 8 weeks after I noticed hearing loss, and 3 weeks after diagnoses.
Went back to part time work immediately, and fulltime work within two weeks.
Mentally I feel great. I have had my AN experience, I am now pretty much over it. If the dizzyness stops I am pretty much back to my old self.
Any symptom I have, now is caused by my tumour changing as it dies (well thats how I see it)
While untreated every symptom I would have was caused by the tumour growing.
One is a positive experience the other is a negative.
While early intervention of a small symptomatic AN would seem rash and unnecessary by many medical professionals.
For my mental health the decision was 100% the right one. I am out the otherside pretty much unscathed by the whole experience, with hearing mostly in tact. (GR 1, 100% speech discrimination)
Reporting
How institutions report on AN's make it very difficult to compare real results.
I think the ANA in conjunction with medical professionals should construct a standard reporting format, which will ultimately assist in identifying the best methods for treatment of an AN.
Despite tens of thousands of people diagnosed with AN's worldwide every year, there is a lack of consolidated knowledge to assist in identifying the best methods.
Standardising the reporting of AN's and possibly a worldwide reporting database would assist in this cause.
Standardising reporting on AN radiosurgery, and knowledge sharing could lead to increased uptake of this method of treatment.
Anyway thats my two bits worth...
