FAQ
The most recent clinical data, based on patients followed up to 10 years, shows the same percentage of implant patients remaining disease free as with either radical prostatectomy or external beam therapy. In addition, the side effects of impotence and incontinence are significantly less with seed implant treatment.
Intraoperative treatment planning uses a high speed computer in the operating room to electronically collect the ultrasound images and automatically calculate the treatment plan with little chance for human induced error. This revolutionary technology was pioneered by Dr. Doggett and is setting the standard for prostate brachytherapy technology. This technology is designed to dramatically increase precision of seed placement , to increase cure rates and decrease complication rates. The system is a platform for technology soon to be introduced including real time virtual needle guidance systems and robotic needle and seed placement systems.
That is not accurate today. Radioactive seed implants were first experimented with in the 1940’s. From 1965 until 1983, many hospitals nationwide performed seed implants. In those days, however, the implants were performed using an “open” implantation method, which involves surgery to expose the prostate gland. In addition, the open method required the physician to feel the prostate gland with his fingers to determine where to place the seeds — an extremely imprecise method. Poor placement of the seeds meant there were areas where the seeds were too far apart and not enough radiation was delivered.
Today, the guesswork is gone. Ultrasound template guidence was invented in the late 1970’s in Denmark to distribute the seeds in a uniform fashion through the prostate, thus eliminating the need for a surgical incision and eliminating the guesswork associated with the freehand technique.
Seed implants are not experimental nor investigational by any criteria. All insurance companies and HMO’s are required to provide coverage for seed implants to their members as it is a covered benefit under Medicare.

True, some patients may not need treatment because their cancer is growing so slowly. On the other hand, prostate cancer is the second most common cause of cancer death in men. In addition, there is no foolproof way to detect how aggressive a cancer will be in any specific patient. Because seed implants generally have significantly fewer side effects, early treatment of the cancer using this method may be an excellent choice for many men — even when other treatments are rejected.
No. The radiation from the seeds is of such low intensity that people around you are in no danger whatsoever.
No. The seeds are imbedded in the prostate gland and are not likely to be passed to another person through sexual activity. You should use a condom for the first act of intercourse after seeding.
The radiation is present in the prostate for approximately 2 to 6 months. After the radiation disappears, the seeds remain in the prostate gland permanently, causing no problems.
Radioactive palladium seeds and radioactive iodine seeds are the two current choices. Both give an equivalent chance for cure. Dr. Doggett uses palladium for his patients because the side effects for palladium are much less than for iodine.
You may need a short course of external radiation two months after the seeds only if your Gleason score is higher than 6 or if your PSA score is over 10. Dr. Doggett’s use of advanced technology has eliminated the need for external radiation in many cases. Higher Gleason and PSA numbers mean there may be some extension of cancer cells through the covering of the prostate gland and giving the external beam radiation is designed to eliminate these cancer cells. The short course of radiation is given to a small area of the pelvis so side effects are quite small.
Protons have not been shown to be any more effective or lower in side effects than standard IMRT external beam radiation. The ICER sudy indicates that the comparative value of brachytherapy is higher than for IMRT and the comparative value for proton therapy is lower than for IMRT.
High intensity focused ultrasound is a new technology for treating prostate cancer. It is 2-4 hour procedure done under spinal or general anesthesia. It has not been approved by the FDA as of August 2010. Studies have shown 15 to 23% of patients will show biopsy proof of cancer after HIFU treatment and an up to 7% incontinency rate. {Crouzet, et al. Eur Urol. 2010 Jul 3 and BJU Int. 2006 Dec;98(6):1193-8 Ficarra, et al}
Cryosurgery involves freezing of the prostate gland under anesthesia to destroy cancer cells. Biopsy proves recurrence after cryotherapy ranges from 14.5% to 38%. Incontinence rate is 4.8% and only 25% of patients could have intercourse after cryosurgery. {J. Urol.2008 Aug; 180(2):554-8. Jones et. Al. Cleveland Clinic}
Robotic prostatectomy has somewhat less blood loss than standard open prostatectomy and a somewhat shorter hospital stay. Return to work time is not radically shortened by the use of the robot over standard open prostatectomy. The overall potency and continence rates were 73.6% and 87.1%, respectively with the robotic approach . Studies have not shown the rate of complications occurring with robotic prostatectomy to be substantially different from those seen with open prostatectomy. Rates of impotence and incontinence are higher with surgery of any type compared to brachytherapy. {Arch Esp Urol. 2007 Sep;60(7):755-65. Martinez-Salamance }{ Expert Rev Anticancer Ther. Singh, et al 2010 May;10(5):671-82}
The chance of the brachytherapy failing in the prostate is very small,1% or less. If this small risk of failure should occur, a second seed implant is possible and has been done successfully and safely. Salvage cryosurgery or salvage prostatectomy is also possible, but all forms of salvage therapy need to be performed by highly experienced practitioners.
