Has any one on the forum had Cyperknife radiation? http://www.cyberknife.com/
 
Starting my research on the different types of radiation.
 
Would like to hear others pro/cons
 
Thanks,

Larry,

My understanding is that cyberknife is a focal therapy used on small identified tumors. I think there are trials going on for use a salvage radiation but it has not been used is this manner and there is very little short or long term data. It has been used successfully for tumors n the brain and liver and just recently for prostate cancer. It is recommended that a 3D mapping biopsy be done to identify the actual tumor.

I think you would be better off with conventional radiation where it can get a large margin as you really don't know where the pc is .

64 years old.

PSA rising for 10 years to 40, free psa 10-15. Had 5 urologists, 12 biopsies and MRIS all neg. Doctors DXed BPH and continue to get biopsies yearly. 13th biopsy positive in 10-08, 2 cores of 25, G6 less than 5%. Scheduled for surgery as recommended by Urological Oncologist.

2nd Opinion from Dr Sholtz, a Prostate Oncologist, said DX wrong, pathology shows indolant cancer, but psa history indicates large cancer or metastasis. Futher tests and Color Doppler confirmed large transition zone tumor that 13 biopsies and MRIS missed. G7, 4+3, approx 16mmX18mm.

Combidex MRI in Holland eliminated lymphnode mets. Casodex and Proscar reduced psa to 0.6 and prostate from 60mm to 32mm. Changed diet, no meat and dairy. All staging tests indicate that tumor is local and non agressive. (PAP, PCA3, MRIS, Color Doppler, Combidex, tumor reaction to diet and Casodex, and tumor location in transition zone). Surgery a poor option because tumor is located next to the urethea and positive margin is very likely; permanent incontenance is also high probability with surgery.

Seed implants on 5-19-09, 3 hours door to door, no pain, minor side affects are frequency and urgency; very controlable with Flowmax and lasted 4 weeks. Daily activities resumed day after implants with no restrictions. Gold markers implanted with seeds to guide IMRT.

25 treatments of IMRT 6 weeks after seed implants. No side affects at all.

PSA at end of treatment 0.02 mostly the result of Casodex. When I stop Casodex next week expect PSA to rise. Next PSA in November. Treatments and side affects have greatly exceeded my expectations. Glad to have this 11 year journey finally conclude.

Larry,  The Dattoli Cancer Center has an interesting article titled "Why Would Anyone Choose Cyberknife?".  Try this link;  http://www.dattoli.com/technology/cyberknife.cfm.  Dr. Dattoli is known for performing Tudpock's Brachy and also for performing Dr. Myers' radiation treatment.  Good credentials, no?  Dattoli also provides links wilth info about other radiation treatments.  Good luck.

JohnT,
I called a cyperknife treatment center and they confirmed that they do not use CyperKnife for Salvage treatment. The lady I spoke to wasn't sure why but though perhaps since there is not longer a prostate to 'target' after surgery.

Thanks for your input! This forum is great for Knowledge.

My brother -49 years old, diagnosed with Pancreatic Cancer mid April (tumor 2.4 cm in the head of the Pancreas) just completed a 5 day session of CyberKnife in Tulsa Oklahoma on Friday 06.18.10 (tumor had doubled in size). Although it is too early to tell if it will be effective in prolonging his life (since the prognosis is grim) it seems to have helped to decrease the amount of pain he was having. The Dr.'s, Tech's and Staff were absolutely terrific. He had 'seeds' implanted a few weeks before the CK and had the first treatment on 06.14.10. The first treatment was difficult because they had to calibrate, so he had to lie there for over three hours, but each day thereafter was about 1-1/2 hrs. He didn't feel a thing during the procedure. Post procedure he had trouble keeping food down, nausea and was very tired, all normal side effects. He also had a bout with unending hiccups (which had happened before the CK as well).

This past weekend he went to a wedding, another party, went swimming, rode his motorcycle and was feeling a lot better. Originally his doctors had him scheduled for 6 weeks (5 days a week) of traditional radiation with 3 chemo sessions on either end of the process. I don't know the technicalities or the effectiveness of CK at this point (we will find out in a few weeks when they do another scan) but the procedure itself was comfortable and pain free.

Hope this was somewhat helpful.
