DNA Ploidy Analysis through Flow Cytometry An objective analysis of prostate cancer cells from a biopsy that enables a more accurate determination of cellular characteristics. You should request this from your doctor before the biopsy to insure sufficient tissue sample. This test compares the number of chromosomes and the DNA in a normal cell. If the cell has two sets of chromosomes and the DNA is normal the cells is called diploid and is normally slower growing. If the cell has more DNA than a normal cell, it is classified aneuploid and has a potential for faster growth. Other combinations that require immediate attention are any combination of aneuploid and/or tetraploid (polyploid), which have the potential to become fast growing. This test is often referred to as the ploidy test and may be valuable because it may assist in determining treatment options.

Foley Catheter A self-retaining tube placed through the urethra into the bladder for continuous urinary drainage.
Frozen Section A technique in which tissue is removed by biopsy, then frozen, cut into thin slices, stained and examined under a microscope. A pathologist can usually rapidly examine a frozen section for immediate diagnosis. This procedure is often done during surgery to help the surgeon decide the most appropriate course of action.
Gleason Score A subjective method of measuring the differentiation of cells to classify tumors by their microscopic appearance and how aggressively cancer cells may multiply. This system divides prostate cancer into five histologic patterns ranging from 1-5. Patterns 1 and 2 represent well- differentiated tumors and are dealt with more easily; Gleason patterns 3 represents moderately well-differentiated tumor cells beginning to scatter; Gleason patterns 4 and 5 indicate poorly differentiated cells with the potential for fast growth. The total Gleason score is determined by adding a primary and secondary score pattern for each prostatic lesion i.e. 3+4=7. The most well-differentiated cancer cells would consist entirely of Gleason pattern 1 ( primary +secondary + 1+1 or Gleason 2 ) and the most poorly differentiated cancer cells would have a 5+5 or total Gleason score of 10.

Perineal Prostatectomy An operation to remove the prostate gland from an opening between the anus and scrotum. The advantage is shorter hospital stay and less bleeding. The disadvantage is that the lymph nodes cannot be examined simultaneously. A separate lymphadectomy is required to examine the lymph nodes. This approach can also be used for the treatment of BPH and cryoprostatectomy.
Placebo A substance that has no real therapeutic pharmacological value i.e., sugar pill instead of an actual medicine. Placebos are often given to patients who require a pill for psychological reasons, but mostly as part of clinical trials to test the effectiveness of new drugs.

Primary cancer/recurrent cancer/second cancer Primary cancer is the location in the body where a specific cancer starts and is represented in the name of the cancer. Prostate cancer is a cancer that starts in the prostate gland. When the primary cancer is treated and then returns, it is called recurrent cancer. When an entirely different cancer unrelated to the primary cancer develops, this is called a second cancer.

Prostate Specific Antigen (PSA) A blood test for the measurement of a substance produced by prostate gland cells. An elevated reading indicates an abnormal condition of the prostate gland, either benign or malignant requiring further investigation. The PSA is the most sensitive "marker" of the prostate cancer currently available and is used to monitor the progress of a patient undergoing treatment as well as after surgery or radiation therapy. There are two PSA assays: The more commonly used is the Hybritech where a score of 0-4 is generally considered within the normal range. The other is called the Yang Pros - Check where a score of 0-2.5 is generally considered within the normal range. To convert from Hybritech to Yang Pros-Check you multiply your assay by .625. To convert from Yang Pros - Check to Hybritech you multiply your assay by 1.625.
Prostatic Intraepithelial Neoplasia (PIN), Proliferative Inflammatory Atrophy (PIA), and Atypical Small Acinar Proliferation (ASAP) Three common conditions found during a prostate biopsy. None of these are cancerous, but many believe that these are either pre-cancerous conditions, or are related to an increased risk of developing prostate cancer in the future.
Protocol The term used to describe an individual's treatment program.
Radiation Therapy (RT) Uses high energy rays to kill prostate cancer cells. Usually healthy cells are also affected. Like surgery, radiation therapy works best when the tumor is small and localized. There are two ways in which high frequency rays can be delivered: one by External Beam Radiation four or five times a week over six or seven weeks; the other by Interstitial Radiation Therapy also referred to as Brachytherapy, receiving rays from tiny radioactive seeds inserted directly into the prostate tumor. Most men are able to have sexual intercourse after interstitial radiation. Other forms of radiation are Proton Beam Irradiation which has high selectivity without damage to surrounding tissue and negligible morbidity; 3-D Directed Radiation which utilizes computer generated scans that provide the ability to confine the radiation selectively to the targeted area without peripheral involvement; and Neutron Therapy which is specialized radio therapy using atomic particles.
Radical Retropubic Prostatectomy An operation to remove the entire prostate gland and seminal vesicles through the lower abdomen.
Refractory A term commonly used to describe a situation where the disease is no longer controlled by current therapy. It amounts to disease progression.
Remission Complete or partial disappearance of the signs and symptoms of disease in response to treatment. The period during which a disease is under control. A remission does not necessarily mean a cure.
Retrograde Ejaculation Semen going backwards into the bladder instead of through the urethra during a male orgasm. This is most often the case following a transurethral resection of the prostate gland (TURP) in the treatment of BPH.
Staging A medical term for the process of determining if a known cancer is still confined within the prostate where it is curable, or if it has spread outside of the prostate gland where it is probably not curable, but treatable. It is a system for classifying patients with malignant disease according to the extent and severity of disease, and thereby helping to determine the appropriate therapy. There are 2 systems for staging Prostate Cancer. The Whitmore-Jewett ranges from A to D with substages for more precise definition.
Survivorship care plan Typically created after an individual undergoes treatment for a condition, like cancer, that can lead to the need to tailor the lifestyle to prevent the condition from returning or progressing further. Aspects of a survivorship care plan include a schedule of follow-up appointments and tests, signs and symptoms of progression or recurrence to watch for, potential late-developing side effects of treatment, and other lifestyle recommendations such as exercise plans, special diets to adhere to, and more.
Testosterone A male sex hormone produced by the testicles with a small amount produced by adrenal glands. It is associated with the activity and growth of the prostate gland and other sex organs.
Transrectal Ultrasound Of The Prostate(TRUS/P) A test using sound wave echoes to create an image of an organ or gland to visually inspect for abnormal conditions like gland enlargement, nodules, penetration of tumor through capsule of the gland and/or invasion of seminal vesicles. It is also extremely useful for guidance of needle biopsies of the prostate gland and guiding the nitrogen probes in cryosurgery.
Transurethral Incision Of The Prostate (TUIP) A surgical technique for treating BPH on individuals with small prostates. It is a simple operation which is less likely to cause a significant loss of blood. The instrument is passed into the neck of the bladder where one or two incisions are made through the wall to open the prostatic urethra.
Transurethral Laser Incision Of The Prostate (TULIP) the use of laser through the urethra which melts the tissue with minimal bleeding and no need for a postoperative catheter.
Transurethral Resection Of The Prostate (TUR/P) also known as Roto-Rooter Procedure A surgical procedure by which portions of the prostate gland are removed through the penis. The technique is used to relieve obstruction of urine flow due to the enlargement of prostate. Many times unsuspected cancer cells are discovered during this procedure when removed tissue is examined by a pathologist. After this operation, semen released during sexual activity usually flows into the bladder rather than out the penis (retrograde ejaculation).
"Tumor Flare" When LHRH agonists may temporarily stimulate tumor growth and symptoms. To prevent this, doctors usually recommend taking the antiandrogen flutamide (eulexin) every eight hours beginning at least two days before the first lupron or zoladex injection.
Ultrasound (Ultrasonography) A non-invasive imaging modality utilizing high frequency sound waves for visualizing tissue. Trancretal Ultrasound is becoming a more prevalent tool in the diagnosis and treatment of prostate cancer.
Ureter The tube that carries urine from each kidney to the bladder.
Urethra The tube that carries urine from the bladder and fluid from the prostate through the penis to the outside of the body. It is the first part of the urethra leading from the neck of the bladder, surrounded by the prostate gland and ends at the external sphincter muscle.
Urologist A doctor who specializes in diseases of the urinary and sex organs of humans.
Vacuum-Tumescent-Enhancement Therapy A mechanical non-surgical method of producing penal engorgement and rigidity sufficient for intercourse in most impotent patients.
"Watchful Waiting" (No Treatment) A term used when a patient and/or physician monitors a potentially dangerous condition. A good example would be PSA monitoring of early stage A or B organ confined prostate cancer.
Whitmore-Jewett Staging Classifications of extent of prostate cancer disease are normally designated by the Whitmore Staging scale composed of alphabetical classifications a-d, followed by numerical prefixes 1-3. Examples would be A1, A2, B1, B2, B3, etc. to D1, D2, D3.
