First SBRT session coming up

Posted by N227 @n227rv, Oct 13 7:08am

My first SBRT session is coming up in two days. Wish me luck. For the record here is where I am at right now..."74 y.o. man with cT1cNx unfavorable risk prostate cancer (GS 3+4 =7, 2/2 cores, iPSA 16.7, MR showing PIRADS 4 lesion right base, probable ECE; PIRADS 4 right apex, broad abutment, no ECE 48cc gland with concern for possible bone lesion in the L posterior acetabulum, PSMA PET negative for mets. IPSS 8, SHIM 14)...All five radiation treatments will be done at Memorial Sloan Kettering in New York. By the way, the bone lesion, whatever it might be, did not light up on the PSMA PET scan.

I was curious I had IMRT 34 sessions. This was to the prostate bed after a prostectomy 3 to 4 years after. I did well for a few years, minor light leakage. Then a few years later I started gradually using 4 to 5 pads a day. I only get at best 3 to 4 hours of sleep. Last night 21/2 hours. Just wondering do you have this problem or similar

@jrs619 My radiation cystitis hit a year later, with back to back UTIs and hematuria. I never had leakage, but I did have my detrusor muscle go into overdrive and leave me afraid to go far from the house, even with pads or absorbent briefs on.

Eventually, Myrbetriq helped the detrusor muscle relax (it took 2× the initial dose), and dietary tweaks calmed down the irritation. I titrated off Myrbetriq after a year.

3½ years later, things are almost back to normal now, except that I go to the bathroom a bit more frequently and get up 1–2× most nights. But I managed a redeye to Europe OK.

Counterintuitively, the biggest help is drinking lots of water. You'd think it would make incontinence worse, but it actually dilutes irritants and flushes them out of the bladder.

This is known possible side effect of RT - worsening of incontinence or developing one.
I am so sorry that it happened to you and that it is effecting your sleep too : (.

@jeffmarc had that happen several years after RT and he resolved it with surgery, maybe you can consider dong that too.

Wishing you the best of luck 🍀

@cadaddy Someone else on the list said the machine they use at MSK is a Elekta Unity MR-Linac. I'll find out tomorrow.

@n227rv The machine used for my SBRT was the Varian Ethos LINAC which is CT guided with real-time AI adjustments. In addition to the prostate, two adjacent lymph nodes were also targeted.

Tip: Wear a urine pad for your first SBRT session.

Maybe not essential, but I think it's a good precaution until you know what to expect during your sessions.

Even if you have no urinary issues, the required "full bladder" might overwhelm your bladder control after a 20-30 minute SBRT session -- especially if the start of your treatment was delayed (2 of my 5 sessions were delayed 15 - 30 minutes).

@retiredboomer71 Boy, that is good advice. My first treatment yesterday was delayed and then delayed again. I went through two sequences where I filled up with water but then couldn't hold it and had to void. Luckily by the time they came for me I had finished my third intake of water and my bladder was just right.

@cadaddy That's the same machine they use for me yesterday.

@surftohealth88 My record said SBRT, but a later oncologist suggested it was wrong, and they changed it.

Regardless, 60 gy in 20 fractions.

I have completed 4 of 5 days. Here are some random observations. First, the machines are, well, machines and they might have issues. At MSK in NY they use the radiation machines for patients who are getting radiation in locations from head to toe, so the machines are in constant use. On Day 1, everybody was backed up, which made for an hour plus delay for me getting started. I have tell you that I couldn't hold a full bladder that long, so I went through two cycles of voiding to empty and drinking to refill. Second, don't tell the staff you're emptying or they might put you to the end of the line. Just pay attention to your bladder and manage things yourself. On Day 3, I was on the same machine when it stopped twice and rebooted. That's when I realized why everyone was backed up on Day 1. Day 3 for me took nearly an hour, including a walk down the hall to another machine - a very uncomfortable session. Third, the staff may have you drink 12 oz of water before the session, but then leave you for 45 minutes so your bladder fills. For me, the water shoots through from mouth to bladder in about 20 minutes, so I learned to calibrate how quickly to drink and by Day 4, yesterday, I was comfortably full for the session. Fourth, the prostate is getting pretty worked over by the radiation, although you will not feel anything happening during the treatment. My urethra was being compressed by swollen prostate tissue, which caused some urinary discomfort. I found ibuprofen helped reduce swelling along with Tamsulosin 0.4 mg once a day. (The RO recommended twice a day if necessary.) Fifth, the prep instructions direct a self-administered enema an hour before the procedure, which makes everything much smoother. One of the first things the staff looks for when the imaging starts is for the presence of a bolus in the rectum. If a bolus is present, the patient has to get off the table and have an enema to clear the rectum. Sixth, it is an odd world, isn't it, where we have to think about things like bladders and rectums? Finally, while in the waiting room I see other cancer patients with no hair sitting in wheelchairs waiting their turn and I realize that things could always be worse.
