Hi Melch,
I assume he's having 40-44 treatments of IMRT? (I assume he's not getting SBRT or HDR brachy, which can also entail planting of fiducials and are highly conformal.)
I think patients should be told about
even the low probability side effects that may occur. Some doctors don't mention them, but I think it ought to be a print-out handed to each patient, the same way one gets a list of possible side effects for every drug one takes. To my mind, if one crops up, you are not surprised, and you know how to deal with it.
Here's a list for IMRT if you want to see it:
Adverse events of primary, intensity-modulated radiation therapy (IMRT)With radiation, urinary difficulties are apt to get worse before they get better. It will probably improve to better than what he's experiencing now, but that can take a year or two. I think it's a good idea to take an alpha blocker (like Flomax) daily from the start of radiation and continue it throughout. He might also take a daily NSAID like Aleve or ibuprofen to help
prevent inflammation. Discuss this with his doctor.
Unfortunately, men with poor erectile function (I'm not talking about
libido, which is a different thing) get worse after radiation. There's conflicting evidence about
whether daily doses of ED meds begun at the start of therapy and continued for 9 months afterwards, may prevent some erectile dysfunction. Because he has lower urinary tract symptoms, his urologist can prescribe daily Cialis for that, and insurance should cover it when prescribed for that purpose.
The best thing he can do to prevent fatigue and other side effects of radiation, and to help the radiation work better, is to vigorously exercise every day. This is not the time to "take it easy."
PSA doubling time is not used to assess risk of untreated prostate cancer. There are just too many factors that affect PSA for that to be a useful indicator. If he is taking Proscar or Avodart, it may be a better indicator.
