From Urology Times Nov. 2008

Dr. Thomas Walsh working with Dr. Paul Turek and others at UCSF note very preliminary data showing a 1.8 fold risk of Prostate Cancer in men with infertility, and a 1.5 fold risk of developing other cancers.

From the Nov. 2008 Urology Times:

Univ. Calif. Davis researchers report patients treated with radiation for initial therapy for prostate cancer, and men treated with radiation for positive margins at radical prostatectomy have a 2-fold risk for developing subsequent bladder or colorectal cancers due to the radiation exposure.

Caution was urged as there are trends towards treating the positive margins before any rise in PSA confirms residual cancer.

Additionally, at the 2009 American Urology Assn meeting, stats were quoted describing a risk of 1% per year of developing a secondary cancer in the bladder or rectum due to radiation exposure.

From the 2008 PCRI Conference:

The Univ. Calif. San Francisco criteria for active surveillance are:

PSA less than 10
Gleason Sum 6 or less
No grade 4 or 5 tumor on biopsies
Less than 33% cores positive, and no core with over 50% involvement with cancer
Stage T1 or T2

_______________________________________________________________________

Treatment is recommended for “Progression” defined as:

Rise in PSA of more than 0.75 ng/dl per year
Lowering of PSA doubling time
Rise in Gleason score on followup biopsies
Increase in tumor size on ultrasound
