Doc: PSA test has a place in treating prostate cancer
Dear Dr. Roach: I read your recent column on PSA screening for prostate cancer. As an oncologist who specializes in prostate cancer, I wanted to add that it is important for patients to understand that 1) screening is very different from diagnosis and treatment, and 2) that the PSA test is a very good and accurate test that does exactly what it is supposed to do: measure the level of PSA in people with prostate cancer.
I’ve heard so many patients, even with metastatic prostate cancer, saying, “I read in the news that PSA is a bad test and doesn’t really matter for my prostate cancer.”
This is entirely untrue.
One of the messages that has trickled out to patients in the controversy over PSA screening is that PSA never matters — again, not true.
For patients who have been treated for prostate cancer or are undergoing treatment for metastatic prostate cancer, the PSA is a very valuable tool. A rising PSA in that setting has very different implications than when a PSA is used for screening. Health-care professionals made a huge mistake when someone decided to biopsy every man with a PSA above 4 for no good reason whatsoever. But for patients with concerning signs and symptoms (which is not “screening”) who have an elevated PSA, it can be meaningful and should not be brushed off — which is happening quite a bit in the community.
Just for full disclosure, I do believe in getting a PSA in some high-risk men (those with a strong family history, symptoms or who are African-American, for example) those in a particular age group (50-70, or those with a life expectancy of at least 10-15 years) after careful counseling to engage the patients re: risks and benefits.

Dear Dr. Won Kim: I thank Dr. Kim for his thoughtful reminder that the PSA test remains a very useful means of following the course of disease in men with diagnosed prostate cancer. I agree completely that some men still may benefit from a PSA test, including men at higher risk due to family history or being African-American.
I also want to specifically agree that when men have symptoms that could be related to prostate cancer, then the PSA test is part of the appropriate workup to discover the cause of the symptoms, and is not screening at all.
Dear Dr. Roach: I have been talking in my sleep for 10 years. How do you get it? I also talk back to people when I’m sleeping. Is it true that when you talk in your sleep and people ask questions about anything you’ve done, you cannot tell a lie?
Dear S.M.: Sleep talking is a common occurrence. It’s not a sign of a physical or mental problem. No treatment is necessary. What makes it happen isn’t clearly understood. If people ask a sleep talker a question, most often, if not always, the talker doesn’t give any answer. Everything a sleep talker says isn’t necessarily the truth.
