Prostate glandThe prostate is part of a man's reproductive system.

An organ located in front of the rectum and under bladder.

It surrounds the urethra.

It secrete a fluid to nourish semen during intercourse.

The prostate is about the size of a walnut but it can grow with age and is called benign prostatic hypertrophy (BPH).

Male hormones(androgens) make the prostate grow.

HISTORY:In 1536 - First described by venetian anatomist Niccolo massa.Until 1853 -Prostate cancer was not identified.19th century- A rare disease, probably because of shorter life expectancies and poorer detection methods.1890s - Surgical removal of the testes to treat prostate cancer but

with limited success. 1904 - Removal of the entire gland was first performed by

Hugh H. Young . 1983 - Radical retropubic prostatectomy was developed by

Patrick Walsh for removal of the prostate and lymph nodes with maintenance of penile function.

20th century -Radical perineal prostatectomy was replaced by transurethral resection of the prostate (TURP) for symptomatic relief.

PROSTATE CANCER

Prostate cancer is a malignant (cancerous) tumor growth.

In prostate cancer, as in other types of cancer, cells grow out of control and form tumors.

The tumor produces little or no symptoms or outward signs .

It can spread beyond the prostate into the surrounding tissues. Moreover, the cancer also can metastasize throughout other areas of the body.

Cancer is thought not to be related to benign prostatic hypertrophy (BPH).

The tumor usually grows slowly and remains confined to the gland for many years.

Mechanism of prostate cancer

Hormones, including the male androgenic hormone, testosterone, could play an important role.

Epigenetic mechanisms may be the main driving force for critical changes in gene expression that are responsible for progression of prostate cancers.

(i) Changing patterns of DNA methylation,

(ii) Histone acetylations/ deacetylations , and

(iii) Alterations in regulatory feedback loops for growth factors.

DNA hypermethylation is an important mechanism in prostate cancer for inactivation of key regulatory genes such as

E-cadherin , tumor suppressors CDKN2 and PTEN and IGF-II.

Stages of Prostate cancer

STAGE I (A1) :

Cancer is found in the prostate only. It cannot be felt during a DRE and is not visible by imaging. It is usually found accidentally during surgery, BPH. The Gleason score is low in PSA test.

STAGE II (A2/B1/B2) :

Cancer is more advanced than in stage I, but has not spread outside the prostate. The Gleason score can range from 2-10.

As prostate cancer progresses from Stage I to Stage IV (TNM System)

CONTINUE……Stage III (C) :

Cancer has spread beyond the outer layer of the prostate to nearby tissues. Cancer may be found in the seminal vesicles. The Gleason score can range from 2-10.

Stage IV (D1 / D2) :

Cancer has metastasized (spread) to lymph nodes near or far from the prostate or to other parts of the body, such as the bladder, rectum, bones, liver or lungs. Metastatic prostate cancer often spreads to the bones. The Gleason score can range from 2-10.

Methods to detect prostate cancer :

Prostate cancer screening is an attempt to find

unsuspected cancers.

1. Digital rectal exam (DRE) :

An exam of the rectum . In prostate cancer

prostate gland becomes hard & lumpy.

2. Prostate-specific antigen (PSA) test :

A test that measures the level of PSA in the

blood. Normally, only very low levels of the enzyme are able to enter the blood stream.

But in prostate cancer PSA leaks into the blood stream, which increases level of PSA in blood (or serum).

Screening :

Screening contd…3. Transrectal ultrasound :

Rectum exam through ultrasound transducer.

To check prostate gland size (tumor) .

4. Biopsy:

The removal of cells or tissues to view under a microscope by a pathologist, who checks for cancer cells and determine the Gleason score.

a. Transrectal biopsy : The removal of tissue from the

prostate by inserting a thin needle through the rectum and into the prostate using transrectal ultrasound to help guide the needle.

b.Transperineal biopsy : The removal of tissue from

the prostate by inserting a thin needle through the skin between the scrotum and rectum and into the prostate.

Diagnosis methods

1. Radionuclide bone scan :

To check if there are rapidly dividing

cells, such as cancer cells, in the bone. A very small amount of radioactive material is injected into a vein and travels through the bloodstream. The radioactive material collects in the bones and is detected by a scanner.

2. Pelvic lymphadenectomy :

A surgical procedure to remove the lymph nodes in the pelvis. A pathologist views the tissue under a microscope to look for cancer cells.

Diagnosis contd….

3. MRI (magnetic resonance imaging)

4. CT scan (CAT scan)

Treatment

Surgical treatment:-

Referred to as a radical or total prostatectomy, which is the removal of the entire prostate gland.

Radiation therapy:-

To damage the cancer cells and stop their growth or kill them. It is used for patients with organ-confined (localized) prostate cancer. It can be given either as external beam radiation or as an implant of radioactive seeds (brachytherapy) directly into the prostate.

Hormonal treatment :-It is to decrease the stimulation

by testosterone of the cancerous prostatic cells . Androgenic deprivation can be accomplished surgically or medically.

Cryotherapy:-

Is one of the newer treatments use in the early stage of prostate cancer. This treatment kills the cancer cells by freezing them by inserting a freezing liquid (liquid nitrogen or argon) through needles directly into the prostate gland.

Chemotherapy

It is used only for advanced metastatic prostate cancers that have failed to respond to other treatments. It is used as a palliative treatment.

Estramustin (Emcyt), Mitoxantrone (Novantrone) is effective in combination with Prednisone for palliating androgen-independent prostate cancer.

Herbal or other alternative medicine treatments

It includes non-traditional treatments as herbs,

dietary supplements, and acupuncture.Wedelia chinensis

ArticlesCancer researchers announce breakthroughs in

natural prostate cancer prevention and treatment .15/12/2009 - (Natural News).

German scientists presented research showing that hops could play a role in preventing prostate cancer. Hops, the flowering clusters of the plant known to botanists as Humulus lupulus.

Valera Seeks FDA Approval for Prostate Cancer Implant.Valera Pharmaceuticals has submitted a New Drug Application (NDA) to the Food and Drug Administration (FDA) for Vantas(TM), designed for the continuous 12-month administration of Histrelin, a luteinizing hormone releasing hormone (LHRH) for the palliative treatment of metastatic prostate cancer.

Organizations:-

1) Prostate Cancer Foundation (PCF) :- Founded in 1993 to find better

treatments and a cure for prostate cancer.

2) Prostate Cancer Support Association (PSA) :-Providing support and information for all those affected by prostate cancer.

3) Give India:-Give India is a donation platform that allows you to support a cause of your choice from about 200 NGOs that have been scrutinized for transparency & credibility.
