QUEST informs readers of the latest advances in urologic prostate cancer research, especially detection, prevention, and treatment.
An Experimental Approach Since 1986, the prostate specific antigen (PSA) blood test has become a routine part of man’s medical regimen. The test measures levels of a protein produced by the prostate and has enabled doctors to diagnose more than…
I am the Secretary of the URF Board and a patient of Dr. Catalona. He performed my radical prostatectomy in September 1997. I’ve written in Quest for over 5 years. I study, write, counsel, and lecture, but I am not…
For over five years, Quest has been reporting on new discoveries in the genetics of prostate cancer that continue to change the way researchers view the development of prostate cancer. In the last issue of Quest, we reported on two…
Lycopene Not Useful In Preventing Prostate Cancer Lycopene, thought to be useful in decreasing the risk for prostate cancer, appears to provide no protection at all. The report is disappointing because popular thinking, even among doctors, was that it could…
Dr. Bruce Seidberg was diagnosed with prostate cancer at the age of 59, almost 10 years ago. It didn’t take him long to choose radical prostatectomy as his treatment. “I checked out alternatives to surgery but soon realized for a…
For the past decade, scientists have been attempting to crack the genetic code underlying the development of prostate cancer. While many scientists came up with possibilities, other researchers were seldom able to reproduce their findings. However, in 2006 Dr. Catalona,…
In recent years, it has become evident that the same patient, who has more than one PSA test, can have different PSA results if the blood samples were sent to different laboratories. Now, we know these differences in reported values…
Researchers are looking for genetic hot spots in prostate cancer patients, and it appears that they found some in a marker area 8q24 (a region labeled 24 on the long arm of chromosome 8). Location, Location, Location “What we’re looking…
Background: Many studies have demonstrated the usefulness of PSA Velocity (PSAV) in prostate cancer screening. However, the often dramatic elevations in PSA values observed in men with prostatitis (PR) could potentially cause confusion in the use of PSAV for CaP…
Background: Since the introduction of widespread PSA screening, prostate cancer has become the leading cancer diagnosis in US men. Even though death from prostate cancer has significantly declined in recent years, there is concern that the treatment of some men…
