I have done exhaustive research on this since I am a gleason 4+3 in 2 of 12 cores. I did NOT qualify for Tulsa due to calcium deposits in my prostate. Needless to say I was very disappointed after going to all the trouble to get in the Mayo clinic. I am now pursuing IRE NanoKnife at Moffitt Cancer center. After all of my research, Tulsa Pro and IRE are the only way to go if you qualify. Very little disruption of your life and very low side effects if any, for only a slightly higher risk of recurrence. The risk of recurrence is 25%+ at 5 years across all methods of treatment and approaches 50% at 10 years for all methods. This depends somewhat on your decipher score and other factors. However, after 15 years, only 3% of deaths are due to prostate cancer. So why not do a less invasive procedure to start. You can always advance to RP, radiation or do Tulsa or IRE a second time.
