Update Update on SBRT treatment
So i want to give my update and thoughts for those considering SBRT. I spent months researching and reading journals after journals before choosing SBRT as a monotherapy with no ADT required for a favorable cancer. I chose it because i did not want to go through the surgery and recovery, i did not want to risk a short penis, incontinence, or erectile dysfunction. With SBRT the cure rates and biochemical control was s the best out of all treatments although statistically the difference was not much and they stacked up basically the same. I also did not want to risk the recurrence that comes with surgery then being forced into radiation as well. With radiation the bowel side effects with the spacer is 1%. Incontinence was virtually zero which was important to me. Im 65 so impotence was a big one as surgery had a much higher rate of erectile issues especially for men my age. A big issue i had that stressed me out was urination retention from high dose SBRT. I have a baseline IPSS score in the moderate range of 12 and thats with taking flomax. But i made the call because i wanted a better margin since my cancer abuts the capsule and surgery cannot provide that. I have a high volume gleason six in the transition zone and its a single lesion 27mm by 13mm. There is only a 10% chance of a missed higher grade as i had a thorough MRI targeted and systematic biopsy. But in case a higher grade is there i wanted a bigger margin around the capsule where it abuts. Also with a single lesion i was able to design a 40g dose on the lesion as a boost and a lower dose everywhere else. I went over a detailed plan with my radiation oncologist and physicist. So with the gold markers and spacer placed i started last Friday and completed 4 of 5 treatments. My final treatment is Monday. I had some urination slowing after the first treatment and after one day following treatment 2 i was urinating so slow and it was trickling out. I was already in a panic if i was going to get blockage since its usually after the third treatment the side effects start. After the third treatment i was urinating 4 times an hour and it was only about 1/2 to 1 ounce and i was like oh crap. All i wanted was to finish the treatments then if i needed a catheter so be it. So i was nervous but went in for treatment 4. Today is a day later and surprisingly the obstruction symptoms are still around the same. They are bad but i can still urinate enough where i am living a completely normal life. Unless im urinating i wouldn’t know i am getting treated. I have no painful urination, no fullness feeling in by bladder etc.. I go to the gym, shopping, whatever i normally do. Urinating is a bitch, but that is all right now. I also surprisingly only get up twice a night to urinate and sleep well. I know now i will be able to finish the fifth treatment on Monday, thank God. After my finall treatment i know i will need to make it a week when that is when symptoms should be peaked and are what they are. I have no idea yet if i will be running to urgent care for a catheter or not, but either way at least my treatment won’t be disrupted and its done as i really wanted this treatment over the rest. Ill keep you posted. Hope this helps men who are considering SBRT and who also has a larger prostate with ongoing BPH symptoms and a higher urinary score. One more thing. I am taking 2 flomax, 0.4mg each, one morning and one at night. Also have 600 mg Motrin for inflammation. Good luck everyone on your journey and i really wanted to post my experience in detail because with a higher IPSS score you can still get SBRT but may have to deal with more obstruction type symptoms like me. But so far i feel great and im almost at the finish line.
