A Genetic Biomarker Test For Newly Diagnosed Prostate Cancer
Results from a study of a different genetic biomarker test suggest that it could one day help inform treatment decisions for men newly diagnosed with localized prostate cancer.
According to findings published February 24 in JCO Precision Oncology, a biomarker test called the Oncotype DX Genomic Prostate Score accurately predicted the long-term risk of metastasis and death from prostate cancer in men with localized disease. The test needs to be validated in larger forward-looking studies before it can be used to guide treatment, the study researchers noted.

Risk Factors For Prostate Cancer
Because prostate cancer tends to not show symptoms in its early stages, risk factors are another useful tool to identify candidates for screening. The Mayo Clinic notes that risk certainly increases as you grow older, and obese men may be more likely to have prostate cancer that is aggressive or difficult to treat.
For unknown reasons, black men are also at a greater risk of prostate cancer than men of other races. Not only are they more likely to get prostate cancer, but the risk of prostate cancer being aggressive or advanced is also higher.
Finally, your family history or genetics can also help determine your prostate cancer risk. For example, men with close relatives who had prostate cancer are more likely to get it. Also, a family history of breast cancer or the presence of the genes BRCA1 or BRCA2 within the family also raises the likelihood of a man developing prostate cancer.

/13do Not Ignore Signs Of Recurrent Prostate Cancer
Prostate cancer can also be recurrent, that means it can return after treatment. When it occurs again around the prostate, it is known as local recurrence. If it has spread to other parts, it is considered metastatic.
That said, the first sign of recurrent prostate cancer may be a rise in the Prostate-Specific Antigen level.
Other symptoms include: Blood in urine, difficulty in urination, fatigue, lower back ache, jaundice.
If you have battled prostate cancer, continue going for screenings.
How Is Prostate Cancer Diagnosed
A biopsy is when a small piece of tissue is removed from the prostate and looked at under a microscope.
A biopsy is a procedure that can be used to diagnose prostate cancer. A biopsy is when a small piece of tissue is removed from the prostate and looked at under a microscope to see if there are cancer cells.
A Gleason score is determined when the biopsy tissue is looked at under the microscope. If there is a cancer, the score indicates how likely it is to spread. The score ranges from 2 to 10. The lower the score, the less likely it is that the cancer will spread.
A biopsy is the main tool for diagnosing prostate cancer, but a doctor can use other tools to help make sure the biopsy is made in the right place. For example, doctors may use transrectal ultrasound or magnetic resonance imaging to help guide the biopsy. With transrectal ultrasound, a probe the size of a finger is inserted into the rectum and high-energy sound waves are bounced off the prostate to create a picture of the prostate called a sonogram. MRI uses magnets and radio waves to produce images on a computer. MRI does not use any radiation.

Advanced Genomic Testing For Prostate Cancer
The most common lab test for prostate cancer is advanced genomic testing, which examines a tumor to look for DNA alterations that may be driving the growth of the cancer. By identifying the mutations that occur in a cancer cells genome, doctors may get a clearer picture of the tumors behavior and be able to tailor a patients treatment based on the findings.

What If My Test Results Are Abnormal
If the results of early detection tests like the PSA test or the digital rectal exam suggest that you might have prostate cancer, your doctor will conduct further testing. The PSA may be repeated, or you may be sent to a specialist for more tests such as a transrectal ultrasound and a prostate biopsy.
In a prostate biopsy, a tissue sample is taken from your prostate. Cancer can only be diagnosed with a tissue sample.
In addition to a PSA test, DRE , and a biopsy, research has yielded additional tests that can detect if cancer is present, and if so, how aggressive that cancer might be:
- The Prostate Health Index combines three blood tests that give a more accurate Phi Score, which gives accurate information based on a high PSA to better determine the probability of finding cancer during a biopsy.

Impact Of Age On Treatment
The rising number of men diagnosed with prostate cancer is a result of increasing life expectancy as well as the current practice of screening by prostate-specific antigen blood tests. Besides PSA and Gleason score, age is considered a key prognostic factor in treatment decision making. Although organ-confined disease can be cured by radical prostatectomy and full-dose local radiation therapy, treatment options for advanced- stage disease remain palliative. They include active surveillance, or watchful waiting, early versus delayed hormonal therapy to control disease progression, and continuous or intermittent androgen deprivation. Observational studies of older men with early stage disease have suggested conservative management as a viable option.,
Chodak and associates evaluated 828 men who were managed expectantly in a series of nonrandomized trials. Median follow-up was approximately 6.5 years. Patients with poorly differentiated cancers had a 10-fold increased risk of death from prostate cancer as compared with men showing highly differentiated prostate cancer. A 5-year disease-specific survival of only 34% was found in men with poorly differentiated prostate cancer. In contrast a 5-year disease-specific survival of 87% was described in men with well-or moderately differentiated cancers.
Repeating The Psa Test
A mans blood PSA level can vary over time , so some doctors recommend repeating the test after a month or so if the initial PSA result is abnormal. This is most likely to be a reasonable option if the PSA level is on the lower end of the borderline range . For higher PSA levels, doctors are more likely to recommend getting other tests, or going straight to a prostate biopsy.

What Are The Prostate Cancer Symptoms I Need To Look Out For
In its early stages, prostate cancer may not show any symptoms. Symptoms of early prostate cancer can include:
- difficulty passing urine
- a slow, interrupted flow of urine
- frequent passing of urine, including at night
Symptoms associated with advanced prostate cancer include:
- pain during urination
- lower back or pelvic pain.
These symptoms are also found in men who may have benign prostatic hyperplasia , a common, non-cancerous enlargement of the prostate gland.
If you experience these symptoms, visit your doctor.
What Are Additional Tests For Detecting Prostate Problems
If the DRE or the PSA blood test indicates a problem may exist, the health care provider may order additional tests, including urinalysis, urodynamic tests, cystoscopy, abdominal ultrasound, transrectal ultrasound with prostate biopsy, and imaging studies such as magnetic resonance imaging or computerized tomography scan.

Dre And Psa Screening Guidelines
SCCAâs prostate cancer specialists recommend the following:
- Men under 40 â DRE and PSA screenings are not recommended for men at average risk.
- Men 40 to 54 â DRE and PSA screenings are not recommended for men at average risk.
- Men 55 to 69 â DRE, PSA or both screenings may be right for you. Talk with your doctor about the risks and benefits.
- Men 70 or older â DRE and PSA screenings are generally not recommended, but older men who are in excellent health may benefit from screening.
Talk with your doctor about screenings if:
- You have any questions about whether DRE or PSA is right for you.
- You have risk factors, such as a family history of certain cancers or inherited genetic mutations that may increase risk.
SCCA prostate cancer doctors are well equipped to discuss the benefits and risks of screening and whether regular screenings are right for you.

Screening For Prostate Cancer
Prostate cancer is typically treatable if caught early. More than 90 percent of prostate cancers are found when the disease is in the beginning stages, confined to the prostate and nearby organs.
Unlike screenings for breast cancer and colon cancer, there are no universal screening guidelines for prostate cancer. The U.S. Preventive Services Task Force recommends that men age 55 to 69 weigh the benefits and risks before deciding whether they should undergo screening, which is typically performed with a blood test that measures levels of a protein called prostate-specific antigen .
However, men in high-risk groupssuch as those who are of African-American descent and/or have a first-degree relative diagnosed with prostate cancer before age 65should consider speaking with their doctor about starting screenings at an earlier age.
Men older than 70 shouldnt be routinely screened for prostate cancer, according to the USPSTF.
Regardless of age or risk factors, men should get checked if they suddenly experience issues with urination, erectile dysfunction or unexplained pain.
The USPSTF suggests that, before deciding on a screening, men should seek expert advice about the benefits and harms of screening. Risks may include:
- False positives

Use In Men Who Might Have Prostate Cancer
The PSA blood test is used mainly to screen for prostate cancer in men without symptoms. Its also one of the first tests done in men who have symptoms that might be caused by prostate cancer.
PSA in the blood is measured in units called nanograms per milliliter . The chance of having prostate cancer goes up as the PSA level goes up, but there is no set cutoff point that can tell for sure if a man does or doesnt have prostate cancer. Many doctors use a PSA cutoff point of 4 ng/mL or higher when deciding if a man might need further testing, while others might recommend it starting at a lower level, such as 2.5 or 3.
- Most men without prostate cancer have PSA levels under 4 ng/mL of blood. Still, a level below 4 is not a guarantee that a man doesnt have cancer.
- Men with a PSA level between 4 and 10 have about a 1 in 4 chance of having prostate cancer.
- If the PSA is more than 10, the chance of having prostate cancer is over 50%.
If your PSA level is high, you might need further tests to look for prostate cancer.
To learn more about how the PSA test is used to look for cancer, including factors that can affect PSA levels, special types of PSA tests, and what the next steps might be if you have an abnormal PSA level, see Screening Tests for Prostate Cancer.
Psa Blood Test For Prostate Cancer
PSA levels are measured as ng/mL. According to the ACS:
- Men with a PSA level between 4 and 10 have about a 25 percent chance of having prostate cancer.
- Men with a PSA level higher than 10 have more than a 50 percent chance of having prostate cancer.
Not all men with high PSA levels have prostate cancer. High levels may also be caused by a urinary tract infection, prostatitis or benign prostatic hyperplasia, all of which are noncancerous conditions. Conversely, men with a low PSA level may still develop prostate cancer.
PSA tests are not an indication of how aggressive the prostate cancer may be. Many prostate cancers are slow-growing and dont require immediate treatment.

Should I Be Screened For Prostate Cancer
Since there are benefits and risks to prostate screening, you should talk with your provider to decide if screening is right for you. You and your provider should consider:
- Your age. The risk of prostate cancer increases after age 50.
- Your family health history. If members of your family have had prostate cancer, your risk may be higher.
- Your race. Prostate cancer is more common in African Americans. They also have a higher risk of developing prostate cancer at a younger age and having more serious disease.
- Your general health. Are you well enough to have treatment for prostate cancer if it’s found?
- What you prefer. How do you feel about the possible benefits and harms of screening, diagnosis, and treatment?

Side Effects Of Radical Prostatectomy
The most common side effects of the procedure are incontinence and erectile dysfunction . The incontinence, though common early after surgery, usually goes away. Whether erectile function returns depends on whether the nerves surrounding the prostate can be spared at surgery, patient age and baseline function. Men who are older or already have erection problems are most likely to have erectile dysfunction afterward.
For more information on erectile dysfunction and treatment, see Managing Erectile Dysfunction A Patient Guide.
Prostate Cancer Urine Test
This test detects the gene PCA3 in your urine and can also help your doctorbetter assess your prostate cancer risk.
PCA3 is a prostate-specific noncoding RNA. Its a gene thats only in yourprostate. If the gene is overexpressed , then theres a greater chance you have prostate cancer.
Like PSA and PHI tests, this isnt definitive, either. But data suggestthat when cancer is present, the PCA3 will be positive 80 percent of thetime. This test can also help your doctor determine whether a biopsy isnecessary.
Both of these new tests are more accurate than the PSA test. Your doctormay recommend one or more than one, based on the specifics of your case.

What Causes Prostate Cancer
The exact cause of prostate cancer is not known. The tumor arises from cells with abnormal deoxyribonucleic acid changes in the prostate. These abnormal cells rapidly grow and divide, invading surrounding structures and can spread to other parts of the body .
Risk factors
There are certain factors that can increase the risk of prostate cancer. These include
- Age: The risk of prostate cancer increases with age and is most commonly seen after the age of 50.
- Race: African American men have a higher risk of prostate cancer than men of other ethnicities. Cancer in African Americans is also more likely to be aggressive.
- Family history: If a blood relative has prostate cancer, it increases the risk as well. Having a family history of genes that increase the risk of breast cancer or a very strong family history of breast cancer also increases the risk of developing prostate cancer.
- Obesity: Obese people have a higher risk of developing prostate cancer, which is also more likely to be aggressive and recurrent despite treatment.
Lymph Node Biopsy As A Separate Procedure
A lymph node biopsy is rarely done as a separate procedure. Its sometimes used when a radical prostatectomy isnt planned , but when its still important to know if the lymph nodes contain cancer.
Most often, this is done as a needle biopsy. To do this, the doctor uses an image to guide a long, hollow needle through the skin in the lower abdomen and into an enlarged node. The skin is numbed with local anesthesia before the needle is inserted to take a small tissue sample. The sample is then sent to the lab and looked at for cancer cells.
