An imaging test of the prostate gland, such as MRI (especially multiparametric MRI) or transrectal ultrasound (TRUS) (discussed in Tests to Diagnose and Stage Prostate Cancer) (If the initial abnormal test was a DRE, the next step is typically to get a PSA blood test (and possibly other tests, such as a TRUS).). Biopsia de prostata – este cea care confirma sau infirma diagnosticul. Aceasta se preleveaza cu ajutorul ecografului transrectal, la care se ataseaza un ac fin, special creat in acest scop. 4. CT, RMN – nu se efectueaza de rutina. RMN poate fi indicat post-diagnostic in vederea planificarii radioterapiei. 5. Diagnostic si investigatii Cancer de Prostata. Majoritatea cancerelor de prostată sunt identificate pentru prima dată în timpul screeningului combinat cu analiza de sânge pentru antigenul specific prostatic (PSA) sau cu un examen rectal digital (DRE).
Dacă prezentaţi risc de cancer de prostată, veţi fi trimis la un spital/oncolog pentru a discuta opţiunile pentru teste suplimentare. Cel mai frecvent utilizat test este biopsia prin ultrasonografia transrectală (TRUS). În timpul acestei biopsii se introduce în rect o sondă cu ultrasunete (un dispozitiv care utilizează undele de sunet.

Prostate cancer metastasis: Where does prostate cancer spread? MRI scans can give doctors a very clear picture of the prostate and nearby areas. A core needle biopsy is the main method used Diagnostic pozitiv cancer prostata trus diagnose prostate cancer. In active surveillance, regular follow-up blood tests, Diagnostic pozitiv cancer prostata trus exams and prostate biopsies may be performed to monitor progression of your cancer. Prostate-specific antigen PSA is a protein made by cells in the prostate gland both normal cells and cancer cells. Waiting for test results can make you anxious.
If your prostate cancer has come back after treatment, the CT scan can often tell if it is pfostata into other organs or structures in your pelvis.

Low-grade prostate cancer may not need treatment right away. A lymph node biopsy prosfata rarely done as a separate procedure. Prostate cancer adult. In active surveillance, regular follow-up blood tests, rectal exams and prostate biopsies may be performed to monitor progression of your cancer. First, you lie down on your left side.
Your biopsy samples will be sent to a lab, where they will be looked at with a microscope to see if they contain cancer cells. Getting the results in the form of a pathology report usually takes at least 1 to 3 days, but it can sometimes take longer.
The results might be reported as: But even if many samples are taken, biopsies can still sometimes miss a cancer if none of the biopsy needles pass through it.
This is known as a false-negative result. If your doctor still strongly suspects you have prostate cancer because your PSA level is very high, for example , your doctor might suggest: If prostate cancer is found on a biopsy, it will be assigned a grade. The grade of the cancer is based on how abnormal the cancer looks under the microscope. Higher grade cancers look more abnormal, and are more likely to grow and spread quickly. There are 2 main ways to describe the grade of a prostate cancer. The Gleason system, which has been in use for many years, assigns grades based on how much the cancer looks like normal prostate tissue. Since prostate cancers often have areas with different grades, a grade is assigned to the 2 areas that make up most of the cancer.
These 2 grades are added to yield the Gleason score also called the Gleason sum. The first number assigned is the grade that is most common in the tumor. Although most often the Gleason score is based on the 2 areas that make up most of the cancer, there are some exceptions when a biopsy sample has either a lot of high-grade cancer or there are 3 grades including high-grade cancer. In these cases, the way the Gleason score is determined is modified to reflect the aggressive fast-growing nature of the cancer. In recent years, doctors have come to realize that the Gleason score might not always be the best way to describe the grade of the cancer, for a couple of reasons: Because of this, doctors have developed Grade Groups , ranging from 1 most likely to grow and spread slowly to 5 most likely to grow and spread quickly :
The Grade Groups will likely replace the Gleason score over time, but currently you might see either one or both on a biopsy pathology report. Along with the grade of the cancer if it is present , the pathology report often contains other information about the cancer, such as:
PIN is often divided into 2 groups: Many men begin to develop low-grade PIN at an early age, but low-grade PIN is not thought to be related to prostate cancer risk.
If low-grade PIN is reported on a prostate biopsy, the follow-up for patients is usually the same as if nothing abnormal was seen. If high-grade PIN is found on a biopsy, there is a greater chance that you might develop prostate cancer over time. This is especially true if high-grade PIN is found in different parts of the prostate multifocal high-grade PIN , or if the original biopsy did not take samples from all parts of the prostate.
Atypical small acinar proliferation ASAP : This might also be called glandular atypia or atypical glandular proliferation. Proliferative inflammatory atrophy PIA : In PIA, the prostate cells look smaller than normal, and there are signs of inflammation in the area. For more information about how prostate biopsy results are reported, see the Prostate Pathology section of our website. Some doctors now recommend that some men with prostate cancer be tested to look for certain inherited gene changes.
This includes men in whom a family cancer syndrome such as a BRCA gene mutation or Lynch syndrome is suspected, as well as men with prostate cancer that has certain high-risk features or that has spread to other parts of the body.
Talk to your doctor about the possible pros, cons, and limitations of such testing. Imaging tests use x-rays, magnetic fields, sound waves, or radioactive substances to create pictures of the inside of your body. One or more imaging tests might be used: Which tests you might need will depend on the situation. If you are found to have prostate cancer, you might need imaging tests of other parts of your body to look for possible cancer spread. Men with a normal DRE result, a low PSA, and a low Gleason score may not need any other tests because the chance that the cancer has spread is so low.
For this test, a small probe about the width of a finger is lubricated and placed in your rectum. The probe gives off sound waves that enter the prostate and create echoes. The probe picks up the echoes, and a computer turns them into a black and white image of the prostate.
You will feel some pressure when the probe is inserted, but it is usually not painful. The area may be numbed before the procedure. Newer forms of TRUS, such as color Doppler ultrasound, might be even more helpful in some situations. MRI scans create detailed images of soft tissues in the body using radio waves and strong magnets.
MRI scans can give doctors a very clear picture of the prostate and nearby areas. A contrast material called gadolinium may be injected into a vein before the scan to better see details. To improve the accuracy of the MRI, you might have a probe, called an endorectal coil , placed inside your rectum for the scan.
This can be uncomfortable for some men. If needed, you can be given medicine to make you feel sleepy sedation. Multiparametric MRI: This newer MRI technique can be used to help better define possible areas of cancer in the prostate, as well as to get an idea of how quickly a cancer might grow.
It can also help show if the cancer has grown outside the prostate or spread to other parts of the body. The results of the different scans are then compared to help find abnormal areas. In this system, abnormal areas in the prostate are assigned a category on a scale ranging from PI-RADS 1 very unlikely to be a clinically significant cancer to PI-RADS 5 very likely to be a clinically significant cancer.
If your initial PSA test was ordered by your primary care provider, you may be referred to a urologist a doctor who treats cancers of the genital and urinary tract, which includes the prostate gland for this discussion or for further testing.
For higher PSA levels, doctors are more likely to recommend getting other tests, or going straight to a prostate biopsy. If the initial PSA result is abnormal, another option might be to get another type of test or tests to help you and your doctor get a better idea if you might have prostate cancer and therefore need a biopsy. Some of the tests that might be done include: For some men, getting a prostate biopsy might be the best option, especially if the initial PSA level is high. A biopsy is a procedure in which small samples of the prostate are removed and then looked at under a microscope.
This test is the only way to know for sure if a man has prostate cancer.
