Early Detection Of Prostate Cancer
To cite this guideline:Carter HB, Albertsen PC, Barry MJ et al: Early detection of prostate cancer: AUA Guideline. J Urol 2013 190: 419.
The clinical guideline on Early Detection of Prostate Cancer discusses the detection of disease at an early, pre-symptomatic stage through the use of screening tools, such as PSA. Early detection allows for more conservative management, if needed, via means such as active surveillance and watchful waiting.

Interpretation Of The Evidence
A major difference in interpretation of the evidence is whether or not the ERSPC and PLCO should be considered equally relevant with respect to the benefits of screening. The trials tested two different hypotheses as noted above screening versus no or little screening in the ERSPC and organized versus opportunistic screening in the PLCO. The latter interpretation of the PLCO trial is in line with statements in the PLCO publications.19,21 A modest effect of PSA screening versus none implies that a substantially larger study than PLCO is needed to meaningfully test more versus less frequent screening. Thus the PLCO was underpowered to address the question of organized versus opportunistic screening. The Panel interprets the randomized evidence to indicate that the ERSPC trial reflects the effect of PSA screening in a situation with low background screening.
Genetic And Genomic Tests For Localized Prostate Cancer
A man’s inherited genes predict his prostate cancer risk. For a long time, we have known that there is a family risk in prostate cancer. If your father or brother has prostate cancer, or your mother or sister has breast or ovarian cancer, you are at higher risk of being diagnosed with prostate cancer. To partially quantify that genetic risk, a germline test can be performed before a biopsy. This test of DNA from healthy cells can determine whether you have inherited genetic mutations, such as BRCA1 and BRCA2, known to increase prostate cancer risk. If the test shows you’re low risk, you may be able to avoid a biopsy even if you have a slightly elevated PSA, while still being actively monitored for prostate cancer.
If already diagnosed with prostate cancer, you may undergo another type of test for assessing your genetic risk. A genomic test of tissue from your biopsy or prostatectomy can look for somatic mutations, alterations in the DNA of the cancer cells themselves. Genomic tests measure expression of various genes that relate to how aggressive a cancer is likely to be. They indicate how rapidly cancer cells are growing and how genetically abnormal they are relative to normal cells.

What Is The Most Effective Treatment For Prostate Cancer
- Radiofrequency ablation A minimally invasive procedure, RFA uses ultrasound or another imaging technique to guide a needle electrode into the cancerous tumor. The electrode then emits high-frequency electrical currents to destroy cancer cells.
- Laparoscopic radical prostatectomy During this procedure, a surgeon will remove the entire prostate. The surgeon will make a few small incisions and insert special instrumentsone of which has a video camera attachedto complete the procedure.
- Robotic surgery For certain procedures, surgeons can use robotic assistance, which can improve precision.
Some patients may also undergo radiation therapy after their surgery to eliminate any lingering cancer cells.
As with other cancers, prostate cancer has the most favorable survival rates when patients are diagnosed early. When prostate cancer is detected before it has spread to the lymph nodes , it is most responsive to treatment and, therefore, more easily cured.
What Can I Do To Prevent Bladder Cancer In Dogs
There is no one particular thing you can do to protect your dog from bladder cancer. You can however provide a life that supports good health and lowers your dogs risk of getting bladder cancer and disease in general.
So, if you are wondering how to prevent cancer in dogs, follow some of these helpful tips:
- Limit Exposure to Lawn Chemicals. If you need to use pesticides, herbicides, and other chemicals for your lawn, inquire from your vet which options on the market are the most pet-friendly. After applying thechemicals, keep your dog indoors at least until the concentration of the chemicals goes down.
- Provide a Healthy Lifestyle. A healthy lifestyle is a key to preventing all diseases. A healthy lifestyle includes a healthy diet, regular physical exercise, pet-safe products, avoiding cancer-causing environmental factors such as cigarette smoke, asbestos, etc. These precautions can go a long way in preventing health issues.
- Frequent Vet Checkups. Early detection is essential to getting a good prognosis for your dog. See your vet as often as you need to to ensure that your dog is in good health and if not, the right treatment is provided as soon as possible. This is especially important for dog breeds that have a genetic predisposition to bladder cancer.
- Responsible Breeding. Inquire from your breeder about the history of the parents of a dog before taking her home. If your dog has a history of bladder cancer, early castration or spaying is highly advisable.
Survival Of Prostate Cancer
Survival depends on many factors. No one can tell you exactly how long you will live.
Below are general statistics based on large groups of people. Remember, they cant tell you what will happen in your individual case.
Survival for prostate cancer is generally good, particularly if you are diagnosed early.
Green Tea Coffee And Red Wine
The health benefits of green tea are thought to come from polyphenols, which include catechinsâpowerful antioxidants. Laboratory and preclinical studies have shown catechins slow the spread of prostate cancer by blocking the stimulating effect of androgen , and they may block a protein involved in the growth of prostate cancer. Catechins also make prostate cancer cells more susceptible to radiation and hormone therapy.
Coffee consumption has been associated with a lower risk of prostate cancer recurrence and progression. In a study reported by Fred Hutchinson Cancer Research Center in August 2013, men who drank four or more cups of coffee a day experienced a 59 percent reduced risk of prostate cancer recurrence and progression compared with men who drank only one or fewer cups of coffee per week. While more studies are needed to determine the mechanisms for this effect, researchers believe that the phytochemical compounds found in coffee have anti-inflammatory and antioxidant effects and modulate glucose metabolism.
Also, according to a study by researchers at the Hutch, men who drank four or more glasses of red wine per week reduced their risk of prostate cancer by half and had a 60 percent lower incidence of more aggressive types of the disease. This may be due to the anti-inflammatory and antioxidant properties of resveratrol, found in red grape skins, peanuts, and raspberries. Resveratrol is also available as a dietary supplement.

Prostate Cancer: Early Detection By Screening Is Key To Survival
- Posted On: Oct 15, 2021
This year alone, nearly 250,000 men will be diagnosed with prostate cancer, the most common cancer detected among males. 60 percent of cases are diagnosed in men aged 65 and older, and thats why its essential for men to schedule a yearly physical as they age. A blood test can detect potential issues with the prostate, including cancer, which is treatable if caught in the early stages.
Is Active Surveillance Right For You
There are some risks associated with active surveillance. They include a low risk of infection with every biopsy and a very low risk of cancer progressing in any one interval of surveillance. Sometimes men choose active surveillance for a period of time and then decide to undergo treatment.
Thousands of UCSF patients have chosen active surveillance to initially manage their prostate cancer. This is one of the largest groups of patients on active surveillance in the world. About one-third of these men receive treatment by five years and 50% by 10 years. The window of opportunity to cure prostate cancer is usually measurable in years or even decades. In fact, treatment results for these men appear to be similar to what would have been expected had they chosen treatment right after their original diagnosis. Based on our experience and those reported from other centers, the risk of significant cancer progression in the short to intermediate term, while not zero, appears to be very low.
Some men with risk factors such as family history, genetic mutations and being African American may still be candidates for active surveillance but need a more careful or intense surveillance regimen to make sure any early signs of progression are identified.
The most common reason for seeking treatment is a biopsy that shows the cancer is growing or becoming more aggressive in appearance . Changes in PSA or cancer stage based on imaging results may also lead to treatment.

Joining A Clinical Trial
Clinical trials are medically supervised, carefully controlled patient studies that attempt to determine whether a proposed new treatment is both safe and effective. Clinical trials also look at whether a new treatment can lead to better outcomes than existing treatments. These studies may involve researchers from a variety of disciplines, such as general medicine, medical specialties, genetics, biology, chemistry, engineering and psychology. Clinical trials are conducted at medical centers around the country, and participants are often actively recruited.
New treatments are continually being developed for prostate cancer. Many prostate cancer trials are designated for patients with a rising PSA after local treatment or for those with advanced, metastatic cancers. However, there are also many trials for men with less aggressive cancer, such as the active surveillance trials at UCSF. We also conduct trials of neoadjuvant treatment, which are medications given before surgery for higher-risk prostate cancer. Several new treatments and approaches show promise some as simple as lifestyle changes in diet and exercise.
Funding sources for clinical trials include the National Cancer Institute, Department of Defense, universities and medical centers, private research foundations, pharmaceutical and biotechnology companies, and various combinations of these groups.
Clinical trials usually occur in phases:
Does It Matter Where Treatment Is Performed
A large body of evidence shows that in the case of surgery for prostate cancer, surgical experience matters greatly. Medical centers and surgeons performing a high number of prostatectomies per year demonstrate better outcomes in terms of both cancer control and quality of life than those performing relatively low numbers. We don’t have similar data regarding radiation outcomes, but performing brachytherapy well certainly requires expertise and experience, particularly in prostate ultrasound. Planning and administering EBRT effectively has many subtleties, which likely translate to better outcomes with more experienced doctors. No matter what the practice volume of specific surgeons or radiation oncologists, they should be able to discuss their own demonstrated outcomes both in terms of cancer control and quality of life.

Baus Radical Prostatectomy Audit
The British Association of Urological Surgeons now publishes the results of radical prostatectomy for surgery performed in the UK. Details of the operations performed by each surgeon and centre are given, with information about the technique used, transfusion rates, postoperative complications and length of stay for individual surgeons and units. The responsibility of entering the data, however, lies with the individual surgeons and is not always complete.

Who Should Have Focal Therapy
Candidates for focal therapy must be carefully selected, most often based on well-performed, image-guided biopsy techniques . Patients with intermediate-grade tumors visible in a single location on imaging may be considered for focal therapy. Low-grade cancers can be treated this way but are usually more suitable for active surveillance. Some doctors feel that cancer close to the urethra can also be treated in this fashion, but there may be a higher risk of side effects or incomplete treatment. Some feel that additional candidates for focal therapy include patients with one dominant tumor as described above and a microfocus of low-grade disease elsewhere. These smaller cancer foci are followed through active surveillance.
Results of ablation therapies to date have been favorable, but the experience and time of follow-up are still limited. In addition, these patients must be evaluated carefully to avoid undertreating their cancer, and after treatment, they need to have periodic imaging, PSA assessment and at least one follow-up biopsy.
Screenings To Detect Prostate Cancer Early
One of the best ways to detect prostate cancer early is through screening â testing to find the disease in men with no prostate cancer symptoms.
Screening can help find some types of cancer at an early stage, when they may have a better prognosis. In fact, screening alone is credited for one-third of the recent decrease in prostate cancer deaths.
The two most common screening tests for prostate cancer are:
- Digital rectal exam
- Prostate-specific antigen test
Talk with your doctor about the benefits and risks of these screenings. Decisions should be based on:
- Your individual prostate cancer risk
- Your overall health and life expectancy
- Your desire for treatment if you are diagnosed with the disease
- Assess the texture of the back of the gland, where most prostate cancers begin.
- Check for any bumps or hard areas that might be cancer.
This exam usually isnât painful and only takes a few seconds.
Since the PSA test was introduced in the late 1980s, doctors have commonly used it along with a DRE to screen for prostate cancer. Because the DRE can sometimes find cancers in men with normal PSA levels, Fred Hutchinson Cancer Center recommends men 55 or older talk to their doctor about whether DRE is right for them. For some men, such as African-Americans or those with a family history of cancer, doctors may recommend screenings starting at an earlier age.
While there is no perfect screening test for prostate cancer, a PSA test is the most common screening.
Treatment Options For Prostate Cancer
Thankfully, research has come a long way when it comes to prostate cancer treatments. A more conservative option is active surveillance, in which PSA evaluations and other tests monitor the growth of prostate cancer.
Surgery, including radical prostatectomy , is another treatment commonly chosen to treat localized or regional prostate cancer. Chemotherapy, radiation therapy, and hormone therapy are also treatment options.
Nearly all treatments have side effects. Deciding what treatment is best is a decision made together with the oncology or urology team. Evaluating cancer statistics as well as the stage of prostate cancer all guide decision-making.
Definition Of Patient Outcomes And Evaluation Metrics
The relatively long survival time and low mortality rate of localized prostate cancer pose a great challenge in risk estimation. To get a more accurate disease prognosis evaluation over a shorter and practical timescale, we define a composite outcome as our event of interest:
Prostate cancer mortality.
The event time is the earliest date of any of these three events. The censoring time is 1 year after the last PSA test. In cases where patients died of other causes before censoring, the censoring time instead is the time of death.
For better insight into the model performances over time, we calculate the time-dependent concordance-index \\):
Here, \\) is the cumulative distribution function at time t, given input feature \. To account for the high censoring ratio, we adjust \\) with the inverse probability of censoring weights. Additionally, we test our models against the more conventional outcome, namely, prostate cancer mortality. In this study, we set the truncation time t to be 2, 5, and 10 years after diagnosis.
Depending if the input \ is time-dependent, we employ two DL models, RDSM and Deep Survival Machine . As a benchmark, we also consider two popular machine learning models, Random Survival Forest and Gradient Boosting Machine , along with the classical Cox model,,,. All three benchmark models are implemented using the scikit-survival package.

Survival Rates For Prostate Cancer
Survival rates can give you an idea of what percentage of people with the same type and stage of cancer are still alive a certain amount of time after they were diagnosed. These rates cant tell you how long you will live, but they may help give you a better understanding of how likely it is that your treatment will be successful.
Keep in mind that survival rates are estimates and are often based on previous outcomes of large numbers of people who had a specific cancer, but they cant predict what will happen in any particular persons case. These statistics can be confusing and may lead you to have more questions. Ask your doctor, who is familiar with your situation, how these numbers may apply to you.
