Prostate Cancer - More Information



Adenocarcinoma of the prostate is the clinical term for cancerous tumor of the prostate. Prostate cancer confined to the gland is usually curable.

According to the American Cancer Society (ACS), prostate cancer is the most common type of cancer in men in the United States. The ACS estimates that about 192,280 new cases will be diagnosed in 2009 and about 27,360 men die of the disease.

Prostate cancer is the second leading cause of cancer death in men, exceeded only by lung cancer. Prostate cancer occurs in 1 out of 6 men, with reports of diagnosed cases rising rapidly in recent years and mortality rates declining, likely due to increased screening.

Treatment for prostate cancer depends on the stage of the disease at diagnosis and the patient's age and overall health. Elderly patients with early stage cancer or co-existing illness may be treated conservatively. The different treatment options I provide include:


Advanced Diagnostic Techniques

The prostate biopsy procedure is the main method used to diagnose prostate cancer. In obtaining a biopsy, your physician performs a surgical procedure using a very thin needle to remove small pieces of prostate tissue from your prostate gland. The tissue collected by the needle is then sent to our diagnostic laboratory for microscopic examination - to evaluate your prostate health - with a particular focus on identifying the potential presence of cancer cells. The pathologist performs the microscopic evaluation. If cancer cells are discovered, the pathologist can assist us in determining the stage and extent of the disease process. Ultimately, our goal is to form a unique plan for your future treatment needs.

Until recently, detecting cancer in your histological specimen (prostate biopsy) was limited to what could physically be seen when looking at the specimen under a microscope. Because a biopsy is only a 1%-2% representation of the overall volume of the prostate gland, and because cancer can present as a small lesion anywhere in the prostate, a common fear is that the biopsy needle may miss a cancerous lesion - leaving behind a hidden (occult) tumor that could possibly evolve into a worsening problem. There is new technology - a test called ConfirmMDx - that addresses this fear. Results of the initial biopsy usually take about a week, and the ConfirmMDx test usually return in an additional 1 to 2 weeks, mainly because the test is only utilized if cancer is not seen under the microscope.

The new test offers valuable information because it extends our detection abilities so we can locate cancer beyond the point of the histological specimen - by millimeters or centimeters from each core (biopsy zone in the prostate) - giving us the ability to project our detection capabilities across almost the entire organ. It does this by detecting a field effect of epigenetic signatures that are unique to prostate cancer (hypermethylation in CaP - specific genes RASSF1, APC, and/or GSTP1). If these signatures are not detected, it gives us the added assurance that your prostate is free of cancer (at least a 90% negative predictive value with this assay). Conversely, if a field effect is detected, these signals will give us valuable information to use in a focused re-biopsy: potentially giving us a timely advantage and greatly improving our chances to find, characterize, and develop a specific plan to deal with prostate cancer if, again, it exists.

Radiation Therapy

Two types of radiation therapy are used to treat prostate cancer: brachytherapy and external radiation therapy (XRT).

Oncotype DX

Oncotype DX is a genetic test of prostate biopsy tissue, indicated for men with low grade prostate cancer to determine the aggressiveness of the cancer and the likelihood of the cancer spreading.


This treatment involves implanting tiny radioactive capsules (called "seeds") into the cancerous prostate. The seeds emit radiation that kills cancerous tumor cells. Men with small tumors confined to the prostate (stage T1 or T2) and those with only moderate prostate enlargement are candidates for brachytherapy. The procedure is performed on an out-patient basis and takes 45-60 minutes. Brachytherapy patients usually resume routine activity within a day or so. For those who additionally have obstructive voiding symptoms, transurethral resection of the prostate (TURP) surrounding the urethra may be performed before brachytherapy is initiated.

External Radiation Treatment (XRT)

XRT is recommended as an alternative to surgery for cure of disease confined to the prostate. XRT is usually given on an outpatient basis for 6-8 weeks. High energy x-rays are projected into the prostate tissue from a machine outside the body. The radiation destroys cancer cells and shrinks the tumor.

Hormonal Therapy

Hormonal therapy for prostate cancer involves the use of medication to block production of testosterone, which prostate cancer cells use to grow. Drugs used for hormonal therapy include Lupron®, Zoladex®, Vantas®, Eulexin®, and Viadur®.

Radical Prostatectomy

Radical retropubic prostatectomy is the "gold standard" treatment for localized prostate cancer. Radical prostatectomy is the surgical removal of the prostate and surrounding tissues, including the seminal vesicles and pelvic lymph nodes.

Good candidates for prostate cancer surgery have one or more of the following characteristics:

  • Generally good health
  • Tumor confined to the prostate gland (Stage T1 or T2)
  • Age under 70 years
  • Life expectancy greater than 10 years

Radical retropubic prostatectomy involves an incision in the lower abdomen. This gives the surgeon access to the prostate, seminal vesicles, and the pelvic lymph nodes. Based on findings intraoperatively and the tumor volume anticipated from the number of positive biopsy cores done before surgery, every attempt is made to save the cavernosal nerves to the penis (nerves providing erection/potency). This maneuver adds little time or complexity to the case and can be offered by most recently trained urologists today, including myself.

DaVinci Robot-Assisted Laparoscopic Prostatectomy

Robot-assisted prostatectomy is a minimally invasive, robotic-assisted surgical procedure that removes the cancerous prostate gland.


Typically, patients remain in the hospital for 2 days after surgery and are catheterized for 7 days postoperatively.

The 10 year survival rate after radical prostatectomy ranges from 75% to 97% for patients with well and moderately differentiated cancer and 60% to 86% for patients with poorly differentiated cancer.

When cancer is confined to the prostate, the disease is usually curable with erectile function and urinary control being salvaged in the vast majority of patients.


Prostate Cancer FAQs

How common is prostate cancer?

Prostate cancer is the most common non-skin cancer in America, affecting 1 in 7 men.

In 2015, approximately 220,800 men will be diagnosed with prostate cancer, and more than 27,540 men will die from the disease. One new case occurs every 2.4 minutes and a man dies from prostate cancer every 19.1 minutes.

It is estimated that there are nearly 3 million U.S. men currently living with prostate cancer.

How does prostate cancer compare with other cancers?

A non-smoking man is more likely to develop prostate cancer than he is to develop colon, bladder, melanoma, lymphoma and kidney cancers combined.

How curable is prostate cancer?

As with all cancers, “cure” rates for prostate cancer describe the percentage of patients likely remaining disease-free for a specific time. In general, the earlier the cancer is caught, the more likely it is for the patient to remain disease-free.

Because approximately 90% of all prostate cancers are detected in the local and regional stages, the cure rate for prostate cancer is very high—nearly 100% of men diagnosed at this stage will be disease-free after five years. By contrast, in the 1970s, only 67% of men diagnosed with local or regional prostate cancer were disease-free after five years.
