Side effects of brachy therapy

Other than more frequent & urgent urination, I had no urination issues and no bowel issues.

I used Depends pads in case of urine dribbles. Good for peace of mind. Stopped after a month or so.

To help prevent urination difficulty, I started taking Tamsulosin (Flomax) about a week before my HDR Brachytherapy (March2024). In retrospect, I probably did not need it. The only side effect I noticed was lightheadedness. IIRC, I stopped taking Flomax after about a month.

A rectal spacer (SpaceOar) was placed on the same day I had HDR Brachytherapy. This was done to protect my bowel from radiation -- especially during subsequent SBRT treatments. The spacer made my poop smaller diameter, so I took a stool softener (Metamucil) after every meal to help prevent constipation.

To OP did you have LDR (seeds) Brachytherapy or HDR Brachytherapy? Did you have a rectal spacer? Did doctors offer you any Flomax, etc for the urinary issues? Great post by retiredboomer71 if you had HDR procedure.

@retiredboomer71 Hi, Great to hear all went well with your HDR Brachytherapy. Do you mind me asking a few questions as I'm having the same HDR Brachy procedure done with SBRT after. Did you do any ADT? What were your stats prior to the treatment? Did you have treatment done at a cancer center of excellence? Thanks and best wishes.

Prior to radiation therapy, at age 71 I was diagnosed Gleason 9 (4+5) with PSA 31. Fortunately only Stage 2 and confined to the prostate.

My one year of ADT (Orgovyx) started Jan2024 about 6 weeks before HDR Brachytherapy + 5 sessions SBRT with Dr Chang at UCLA, a center of excellence.

So far, VERY successful outcomes:
-- PSA consistently in the 0.2's over the past year
-- testosterone recovered quickly and actually increased to 521 from pre-treatment 454
-- I'm guessing my prostate is smaller because urination frequency is a bit less
-- my adult acne is almost completely gone, which I believe is a result of reduced inflammation
-- I feel great! And very grateful.

Most importantly, so far there's no evidence of disease. So hopefully no recurrence anytime soon.

Negatives? Trigger finger & some stiffness developed in both hands that eases with use, neuropathy on the bottom of both feet, ED that responds to Tadalafil.

Best wishes.

I didn't have much in the way of side effects from my high dose rate brachytherapy. I was reluctant to touch my perineum as I felt it would be painful due to all the needles they put in there during the procedure but I don't recall any actual pain. (see the attached graphic of HDR needle placement). My pretreatment research explained it was fairly typical to be bothered by urinary side effects for a long enough period afterwards I'd think things would never return to normal, before they resolved. My experience was almost nothing happened. No burning on urination.

The HDR was followed by 20 sessions of external beam.

I crashed after the external beam treatments. For several weeks I experienced fatigue such as I had never experienced before. Resting did nothing to make me feel better. All food tasted bad. I lost 5 pounds very quickly until I forced myself to eat even when I'd feel like I would just throw it all up soon after. Although I had a serious commitment to make it to the gym no matter what, there were days I could not make it. The recovery was extremely gradual, but at least after the first two weeks or so there was a tiny but noticeable improvement every day or few days.

I think the crash was not just the external beam, or a combination of the HDR + external beam. I think it was a culmination of the RT treatments plus the stress of being diagnosed, finding myself facing a serious disease, and trying to make up my mind about where to be treated and how to be treated.

At one point, after I had committed to a prostatectomy, I read the surgeon's clinical note and found in bold type that he had strongly recommended against surgery. The surgeon had not mentioned this to me during the appointment where he had scheduled the surgery. I found it very stressful to realize I had to be wary of things like this, as I cancelled out on ever seeing this guy again.

I had also just committed to a move, i.e. selling our house and buying another one. I was packing up and trying to settle into a new place at the same time. To be treated I had to figure out how to live in the big city 3 hours from my home for about a month.

Eventually, after somewhat more than a month, all the side effects are gone. My LUTS has improved from what they were prior to the radiation treatments, probably due to a shrinkage of my prostate. I have no "bowel bother" at all.

My HDR was conducted by an expert brachy therapist at an NCI designated institution, Fred Hutch in Seattle. My pretreatment research indicated it was important to get brachy from a very experienced doctor - more important than who did the external beam. The external beam was at the same place.
