PI-RADS Prostate Cancer Diagnosis Pathway – Video Summary with annimations

A enlarged prostate can also cause blockages in the urethra. A blocked urethra can also damage the kidneys. A patient suffering from an enlargement of the prostate may have pain in his lower abdomen and genitals. If pain is present, a digital rectal examination will reveal hard areas. A doctor may prescribe surgery or perform an endoscopic procedure. If the enlarged prostate is not completely removed, it will shrink.

While the size of an enlarged prostate will influence the extent of urinary symptoms, men may experience a range of urinary symptoms. Some men have minimal or no symptoms at all. Some men will have a very enlarged prostate, whereas others will have a mild enlargement. Generally, the symptoms can stabilize over time. Some men may have an enlarged prostate but not notice it. If they have an enlarged colon, their physician can perform a TURP procedure.

Potential Strategies To Reduce Further Harm

Excluding PI-RADS 3 lesions from targeted biopsies

Excluding PI-RADS 3 index lesions from targeted biopsies would result in a reduction of 25% targeted biopsies, however, still missing 18% of all upgrades to GS 3+4. Missed upgrading to GS 4+3 would be 5% .

Stratifying to PSA-density before targeting suspicious MRI lesions

Figures 4 and 5 show the number of men with targeted biopsies, stratifying to PIRADS and to PSA-density.

Figure 4Figure 5

PSA-density cut-off 0.15 ng/mL2

Upgrades to GS 3+4 in PI-RADS 3 lesions were all identified in men with a PSA-density of 0.15 ng/mL2. Hence, when first stratifying according to a PSA-density cut-off 0.15 ng/mL2 in men with a PI-RADS 3 lesion, would result in a MRI-targeted biopsy reduction of 36% in this category, without missing any upgrade to GS 3+4 or higher. These results are plotted in Figure 5 to visualize the amount of additional MRI testing with targeted biopsies, in men with initially low-risk disease on AS. The PSA-density thresholds of 0.15 and 0.20 ng/mL2 are depicted as dotted lines.

Even for PI-RADS 4 lesions, risk stratification by PSA-density could be beneficial if adjustment to potential risk inflation is performed: only 1% of all upgrades would have been missed, reducing 43% of targeted biopsies in this category.

Tests To Diagnose And Stage Prostate Cancer

Most prostate cancers are first found as a result of screening. Early prostate cancers usually dont cause symptoms, but more advanced cancers are sometimes first found because of symptoms they cause.

If prostate cancer is suspected based on results of screening tests or symptoms, tests will be needed to be sure. If youre seeing your primary care doctor, you might be referred to a urologist, a doctor who treats cancers of the genital and urinary tract, including the prostate.

The actual diagnosis of prostate cancer can only be made with a prostate biopsy .

Use In Men Already Diagnosed With Prostate Cancer

The detection of significant prostate cancer is correlated with the ...

The PSA test can also be useful if you have already been diagnosed with prostate cancer.

In men just diagnosed with prostate cancer, the PSA level can be used together with physical exam results and tumor grade to help decide if other tests are needed.
The PSA level is used to help determine the stage of your cancer. This can affect your treatment options, since some treatments are not likely to be helpful if the cancer has spread to other parts of the body.
PSA tests are often an important part of determining how well treatment is working, as well as in watching for a possible recurrence of the cancer after treatment .

Risk Factors You Cant Control

Growing older is the greatest risk factor for prostate cancer, particularly after age 50. After age 70, studies suggest that anywhere from 31% to 83% of men have some form of prostate cancer, though there may be no outward symptoms. Family history increases a manâs risk: having a father or brother with prostate cancer more than doubles the risk. African-American men and Caribbean men of African descent are at high risk and have the highest rate of prostate cancer in the world.

Data Synthesis And Statistical Analysis

We derive pooled estimates and 95% confidence intervals of the cancer detection rates of the PI-RADSv2.1 assessment categories with random-effects meta-analyses of proportions . Since the inverse variance method for estimation of confidence intervals is problematic for values close to 0 or 1 , we use the double arcsine transformation of proportions . Heterogeneity of cancer detection rates between studies is investigated with the I2 statistic . I2 measures the relative amount of variation between studies beyond what can be expected due to chance alone , values range between 0% and 100% . We consider an I2> 50% to denote considerable heterogeneity. We also report the between-study variance of the random-effects models as a quantitative absolute estimator of the extent of heterogeneity.

Possible publication bias is graphically examined by inspection of funnel plots . Following the recommendation of Hunter et al., we plot study size on the y axis instead of standard error . Eggers test is employed for analyses with10 studies to test for asymmetry .

What Are The Symptoms Of Stage 4 Prostate Cancer

While prostate cancer has very recognizable symptoms, the big problem is that these symptoms are very similar to other conditions, such as benign prostatic hypertrophy , and many men brush them off as just getting older. While many of these symptoms can be attributed to aging, it is vital for men to understand that they should not be ignored or marginalized. These symptoms should always be taken seriously. According to the American Cancer Society and the Mayo Clinic, symptoms of prostate cancer, and more specifically, stage 4 prostate cancer may include:

Painful urination
Bone pain, often in the hips, back, and upper legs
Swelling in the legs

Experiencing these symptoms, especially a combination of these symptoms, is a sign that you need to see your physician without delay. As a wife, sister, and daughter, I have heard the men in my life, quite vociferously, explain how they dont want to go to the doctor especially for that exam. Please gentlemen, we beg you get it checked, and get it checked regularly a very quick exam could save your life. The American Cancer Society recommends the following screening times :

Age 50 for men who are at average riskof prostate cancer and are expected to live at least 10 more years.
Age 45 for men at high riskof developing prostate cancer. This includes African Americans and men who have a first-degree relative diagnosed with prostate cancer at an early age .
Age 40 for men at even higher risk.

What Is The Life Expectancy For Stage 4 Prostate Cancer

Recent Advancements in PI RADS: mpMRI vs. bpMRI

Prostate cancer life expectancy is determined using five-year survival rates. This is the percentage of people who may still be alive five years after being diagnosed.

The five-year survival rate for men with localized prostate cancer, where there is no evidence of cancer spreading outside the prostate, and regional prostate cancer, when cancer has migrated outside the prostate to adjacent structures or lymph nodes exclusively, is approximately 100 percent.

When prostate cancer reaches stage 4 and has spread to other organs such as the lungs, liver, or bones, the five-year survival rate falls below 30%. At stage 4, prostate cancer is unlikely to be cured, although with effective therapy, many people can live for several years. The patients life expectancy is determined by the precise characteristics of his cancer.

However, thanks to routine screening procedures, prostate cancer is often discovered early, before it has spread to other organs, and it is usually not fatal. When diagnosed early, there are several treatment options available, as well as a good likelihood of a cure.

Outlook For Men With Localised Prostate Cancer

Most localised prostate cancer is slow-growing and may not need treatment or shorten a mans life. For many men who have treatment for localised prostate cancer, the treatment will get rid of the cancer. For others, treatment may be less successful and the cancer may come back. If this happens, you might need further treatment.

How Long Can Someone Live With Stage 4 Cancer

Doctors usually describe a persons outlook using the 5-year survival rate. These are calculated based on data from thousands of other people with a similar cancer at a similar stage.

The original location of the cancer determines its type. Survival rates vary, depending on the type of cancer and how far it has spread within the body.

Below, we describe the survival rates for some of the most common forms of cancer in stage 4:

Enzalutamide Improves Survival In Patients With Metastatic Prostate Cancer

Summary

In an international randomized phase III clinical trial, the hormone therapy enzalutamide extended survival in men with metastatic prostate cancer that had progressed during treatment with androgen deprivation therapy. Participants in the trial had not received chemotherapy.

New England Journal of Medicine, June 1, 2014.

Background

Early in their development, prostate cancers need relatively high levels of male sex hormones to grow. The testes are the main source of androgens, and treatments that stop the testes from producing male sex hormonesknown as hormone therapy or androgen deprivation therapy are therefore a common treatment for androgen-sensitive prostate cancer. However, most prostate cancers eventually become castrate resistantthat is, they can grow even when androgen levels in the blood are very low. ADT does not block production of the small amount of androgen that is made by the adrenal glands and by prostate cancer cells themselves, and this low level is sufficient to fuel the growth of castrate-resistant prostate cancers.

Enzalutamide is among several hormone therapies that have been developed to prevent the androgen-fueled growth of castrate-resistant prostate cancers. This drug works by keeping androgens from binding to the androgen receptors on prostate cancer cells.

The Study

Men in the trial were randomly assigned to receive 160 mg of enzalutamide or a placebo taken orally once daily.

According to latest statistics, more than 2,795,592 men are currently living in United States with prostate cancer yet estimated number of deaths due to prostate cancer in the year 2015 is 27,540 .

The local stage indicates that the cancer has not progressed to any area outside of the prostate gland the survival rate in local stage is approximately 100 percent. Most of the cases are diagnosed in this stage.

In this type, the cancer advances to the surrounding tissues around the prostate gland. The survival rate is approximately 100 percent if treatment is sought early.

This is the most advanced stage of prostate malignancy in which the cancer cells invade lymph nodes and distant organs . The survival rate is 28 percent.

Tumor Size And Prostate Cancer Death Rate

Prostate cancer is one of the leading causes of morbidity and mortality in men. The pathophysiology of prostate malignancy revolves around abnormal extra-mitotic division of cells that may compromise the normal functioning of prostate gland. It is imperative to mention that the lifetime risk of developing prostate malignancy is 14% . Based on latest statistics, age-adjusted mortality rate due to prostate malignancy is 21.4 per 100,000.

In order to assess and stage the malignancy, several classification criteria are used such as gleason scoring, PSA levels etc. This is mainly because correct diagnosis and staging of the disease is one of the key step in the treatment process.

Your doctor may initially do a digital rectal exam to feel for bumps or hard spots on the prostate. After a discussion with your doctor, a blood test can be used to measure prostate-specific antigen , a protein produced by prostate cells. An elevated level may indicate a higher chance that you have cancer, but you can have a high level and still be cancer-free. It is also possible to have a normal PSA and have prostate cancer.

What Is The Most Effective Treatment For Prostate Cancer

The choice of treatment for prostate cancer depends on many factors such as the patients prostate cancer risk as calculated from prostate-specific antigen levels, Gleason score, and tumor staging. Patients can discuss the significance of these factors in the choice of treatment with their doctor.

The standard effective treatment choices for men with early-stage prostate cancer are as follows

Active surveillance: Monitoring the progression/status of the low-risk or early-stage cancer with regular testing and not treating it right away.
Prostatectomy: Surgical removal of the prostate.
Radiation therapy: Use of high-energy waves to destroy cancer cells.

Radiation therapy is one of the most effective treatments for many men with early-stage prostate cancer. It is also the best prostate cancer therapy for older men or those with other co-existing diseases. It can be delivered to the patient in any of the two ways

External beam radiation: Sending/focusing high-energy waves from an external machine into the tumor.
Brachytherapy: Placing a radioactive dye in the tumor through an implant or hollow tubes.

For metastatic prostate cancer, androgen deprivation therapy is usually the choice of treatment. ADT is also the only option in patients with prostate cancer who are unfit or unwilling to undergo surgery or/and radiation therapy.

Introduction To Clinical Context And Proposed Utility Of Modality

Can PIRADS Determine Treatment?, Detecting Pelvic Lymph Nodes

MRI became the method of choice for detection and staging of prostate cancer . Adapted from breast imaging a Prostate Imaging Reporting and Data System was published by the European Society of Urogenital Radiology : PI-RADS version 1 . This first guideline paper was based on a summary score for each lesion assessed in different sequences of mpMRI, consisting of T2w, DWI and DCE-MRI and spectroscopy facultatively. These guidelines have been updated recently by a steering committee including the American College of Radiology , ESUR and the AdMeTech Foundation to the PI-RADS v2 . In this version spectroscopy was omitted and DCE-MRI was attributed a minor role. In contrast to version 1 each lesion is attributed a single score based on findings of mpMRI. The objectives of these guidelines were to promote global standardisation of prostate imaging, to improve detection, localisation, characterisation, risk stratification of prostate cancer in treatment naïve prostate as well as to improve communication with referring urologists. The latest PI-RADS version assesses the likelihood of clinically significant prostate cancer on a 5-point scale for each lesion as follows:

PI-RADS 1 Very low
PI-RADS 2 Low
PI-RADS 3 Intermediate
PI-RADS 4 High
PI-RADS 5 Very high

Classification Of Prostatic Diseases

Common diseases of the prostate include acinar adenocarcinoma, BPH, chronic prostatitis, hemorrhage, cysts, calcifications, atrophy and fibrosis. Uncommon diseases of the prostate include tumors other than acinar adenocarcinoma, granulomatous prostatitis containing tuberculosis, abscesses and so on, and idiopathic disorders such as amyloidosis and exophytic BPH.

Many conditions that yield abnormal signals within the prostate, including hemorrhage, cysts, calcifications, atrophy and fibrosis, are benign and highly recognizable on mpMRI . In addition to these benign signal abnormalities and based on the applicability of PI-RADS assessment, we divide other focal signal abnormalities involving the prostate into two categories according to the patients age, serum PSA level, symptoms and mpMRI findings: category 1, diseases for which the PI-RADS assessment is suitable for use, and category 2, diseases for which the PI-RADS assessment is not suitable for use. Category 1 includes prostate cancer , typical BPH in the transitional zone , and some types of prostatitis/granulomatous prostatitis, which overlap in terms of clinical and mpMRI findings, while category 2 includes tumors except for PCa, exophytic BPH nodules, and some types of granulomatous prostatitis , for which PCa may be excluded according to the clinical and MRI findings.

Imaging Of Metastasis Status In Prostate Cancer Patients

The screening for PSA level in the serum of patients was introduced in the late 1980s and enabled a dramatic increase in early PCa detection . On the other hand, PSA is not solely a PCa-specific biomarker and, as such, leads to overdiagnosis and overtreatment of clinically insignificant cases, representing a significant burden for patients . Moreover, absolute PSA level does not always correlate with prognosis . Therefore, more specific and sensitive PSA-based values like PSA density , PSA velocity , free-to-total PSA , and PSA doubling time are seen as options with stronger predictive value. For example, PSADT is defined as the length of time for two-fold PSA level increase. A PSADT < 6 months is strongly associated with metastatic disease, increased PCa mortality , and relapse . Nonetheless, the reported benefit of PSADT in PCa management did not enter clinical routine and some studies even reported discrepant results indicating that further studies are required to determine the reliability of PSADT and other available biomarkers .
