PSA after radiation treatments?

Predicting absolute PSA values after radiation has no scientific validity. Hopefully though, it will be lower than pre-treatment and will go down as time progresses until a nadir is reached. The latter can take several years
More info would be helpful (original PSA etc.)

Since you are on ADT it will push your PSA to undetectable very quickly and should stay there while you are on ADT anD for at least three months after your last shot has worn off.

I had ADT and radiation. My PSA went from 59 to undetectable in about 70 days or less.

Because if the ADT you will not be able to gauge the radiation effectiveness until you are off ADT and have regained a more normal testosterone level. Sr Sailor’s comments are more relevant for someone not using ADT.

How long are you planning to be on ADT? Being high risk, I would expect 18 months or so. If that is the case you really won’t know what the radiation has done for a couple of years. Most radiation men do not stay at undetectable PSA long term since they still have a prostate. But most stay at 1.0 or less. A few get to undetectable as I have and continue to be after nearly 10 years.

Thanks for the information. Based on my experience my advice for you is to relax, test PSA quarterly, trust the treatment and work on improving your overall health. Killing PCa with radiation is very effective, just a long slog. Average time to PSA Nadir is 44 months.

Do test PSA frequently to make sure the ADT is working. Also test testosterone at least every 6 months. Being on long term ADT can be tough on the bones. Get a bone density test and then one each year. Make sure your Vitamin D level is good and consider D and calcium supplements.

Exercise, diet and positive attitude will be best in managing the ADT effects of hot flashes, weight gain, fatigue and brain fog. Work your way through. Diet modifications to eliminate caffeine, carbonated and acidic drinks, less alcohol, more fresh fruits and vegetables will all help.

You are high risk, but have chosen a very effective treatment plan. Trust the treatment and do what you can to improve overall quality of life. Best wishes.
