Prostate cancer is a form of cancer that develops in the prostate gland. The prostate gland is about the size of a walnut and weighs about one ounce, it is located below the bladder and in front of the rectum.
In men, prostate cancer is the most frequently diagnosed cancer in 112 countries worldwide, making it most common type of cancer incidence.
Prostate cancer is the most most common cancer among men in the United States. It is also one of the leading causes of cancer death among men of all races and Hispanic origin populations.
Prostate cancer cells can spread by breaking away from a prostate tumor. They can travel through blood vessels or lymph nodes to other parts of the body. After spreading, cancer cells may attach to other tissues and grow to form new tumors, causing damage to other parts of the body.
Prostate Gland
The prostate is a walnut-sized gland located behind the base of the penis, in front of the rectum, and below the bladder. It surrounds the urethra, the tube-like channel that carries urine and semen through the penis.
The prostate’s main function is to make seminal fluid, the liquid in semen that protects, supports, and helps transport sperm.
The prostate continues to enlarge as people age. This can lead to a condition called benign prostatic hypertrophy (BPH), which is when the urethra becomes blocked. BPH is a common condition associated with growing older, and it has not been associated with a greater risk of having prostate cancer.
Prostate Cancer Overview
Prostate cancer is somewhat unusual when compared with other types of cancer. This is because many prostate tumors do not spread quickly to other parts of the body. Some prostate cancers grow very slowly and may not cause symptoms or problems for years or ever.
Even when prostate cancer has spread to other parts of the body, it often can be managed for a long time. So patients with prostate cancer, and even those with advanced prostate cancer, may live with good health and quality of life for many years.
However, if the cancer cannot be well controlled with existing treatments, it can cause symptoms like pain and fatigue and can sometimes lead to death.
Histology is how cancer cells look under a microscope. The most common histology found in prostate cancer is called adenocarcinoma. Other, less common histologic types include neuroendocrine prostate cancer and small cell prostate cancer.
These rare variants tend to be more aggressive, produce much less PSA, and spread outside the prostate earlier.
Prostate-Specific Antigen (PSA)
Prostate-specific antigen (PSA) is a protein produced by cells in the prostate gland and released into the bloodstream. PSA levels are measured using a blood test. Although there is no such thing as a “normal PSA” for anyone at any given age, a higher-than-normal level of PSA can be found in people with prostate cancer.
Other non-cancerous prostate conditions, such as benign prostatic hypertrophy (BPH) or prostatitis can also lead to an elevated PSA level. Prostatitis is the inflammation or infection of the prostate.
In addition, some activities like ejaculation can temporarily increase PSA levels. Ejaculations should be avoided before a PSA test to avoid falsely elevated tests. People should discuss with their primary care doctor the pros and cons of PSA testing before using it to screen for prostate cancer.
Prostate Cancer Gleason Score
The Gleason scoring system is the most common prostate cancer grading system used. The pathologist looks at how the cancer cells are arranged in the prostate and assigns a score on a scale of 3 to 5 from 2 different locations. Cancer cells that look similar to healthy cells receive a low score.
Cancer cells that look less like healthy cells or look more aggressive receive a higher score. To assign the numbers, the pathologist determines the main pattern of cell growth, which is the area where the cancer is most obvious, and then looks for another area of growth.
The doctor then gives each area a score from 3 to 5. The scores are added together to come up with an overall score between 6 and 10. Gleason scores of 5 or lower are not used. The lowest Gleason score is 6, which is a low-grade cancer. A Gleason score of 7 is a medium-grade cancer, and a score of 8, 9, or 10 is a high-grade cancer. A lower-grade cancer grows more slowly and is less likely to spread than a high-grade cancer.
Prostate Cancer Treatments
There are several different ways to treat prostate cancer. The treatment is determined by how advanced the cancer is, whether it has spread outside the prostate, and overall health of the patient.
Prostate cancer usually grows very slowly. This means that the patient can live a full life without ever needing treatment or experiencing symptoms.
If the doctors believes the risks and side effects of treatment outweigh the benefits, they may recommend active surveillance. This is also called watchful waiting or expectant management.
Your doctor will closely monitor the cancer’s progress with blood tests, biopsies, and other tests. If its growth remains slow and doesn’t spread or cause symptoms.
Following are some of the treatment options for Prostate cancer:
Bay Biosciences is a global leader in providing researchers with high quality, clinical grade, fully characterized human tissue samples, bio-specimens and human bio-fluid collections.
Samples available are cancer (tumor) tissue, cancer serum, cancer plasma cancer PBMC and human tissue samples from most other therapeutic areas and diseases.
Bay Biosciences maintains and manages its own bio-repository, human tissue bank (biobank) consisting of thousands of diseased samples (specimens) and from normal healthy donors available in all formats and types.
Our biobank procures and stores fully consented, deidentified and institutional review boards (IRB) approved human tissue samples and matched controls.
All our human tissue collections, human specimens and human bio-fluids are provided with detailed samples associated patient’s clinical data.
This critical patient’s clinical data includes information relating to their past and current disease, treatment history, lifestyle choices, biomarkers and genetic information.
Patient’s data is extremely valuable for researchers and is used to help identify new effective treatments (drug discovery & development) in oncology, other therapeutic areas and diseases.
This clinical information is critical to demonstrate their impact, monitor the safety of medicines, testing & diagnostics, and generate new knowledge about the causes of disease and illness.
Bay Biosciences banks wide variety of human tissue samples and biological samples including cryogenically preserved at – 80°C.
Including fresh frozen tissue samples, tumor tissue samples, FFPE’s, tissue slides, with matching human bio-fluids, whole blood and blood derived products such as serum, plasma and PBMC’s.
