I was corresponding with someone a couple days ago on one of the posts on this site. He said he was using nitroglycerine patches to possibly show his cancer. I was intrigued by this, especially because I have angina as well as the cancer. Here is the study summary from 2010 supporting use use of a nitro patch to fight PCx:
But here is an article showing that continuous nitroglycerine usage can weaken the hearts defenses and make heart attacks worse. There doesn't seem to be much discussion about high vs low dosages or whether the risk is only present once you have a heart attack but maybe it does not cause a heart attack:
Interesting but the trial is over a decade old. I would think that if it had benefit other trials would have been performed.
Personally, I wouldn't put a lot of stock in it. The government has overseen one trial. No results were posted.
If I did decide to risk it, I would monitor my PSAs and scans to see if it might be having an affect. And I would be cautious about the dosing. And I'd watch for any side effects.
It all depends on the person having coronary artery disease or not. For people without coronary artery disease, (no angina, normal stress test and functional echo, low calcium score etc.) it may not be a problem to use a nitro patch.
Note that nitroglycerine patches have been used since Alfred Nobel's time - ironically, he was a user. With such a long history I assume that they are fairly safe.
