What is the best test for bladder cancer?
Several types of urine test have an important role in the overall process of diagnosing bladder cancer. Among these tests, urine cytology and urine tumor marker tests are used to detect the presence or absence of bladder cancer. Urine cytology has been used to assist bladder cancer diagnosis for over 75 years and has well-established strengths and limitations which are discussed in more detail below. Molecular tumor marker tests such as Cxbladder have been more recently developed, and provide high diagnostic accuracy in both detection and rule-out.
How to collect urine samples?
Urine samples are usually obtained by spontaneous voiding, using the clean-catch, midstream urine collection method. This involves voiding the first portion of urine into the toilet, collecting the midstream portion into a clean container, then voiding the remaining portion into the toilet. This method greatly reduces the risk of contaminants entering the sample. Less commonly, an invasive method of urine collection, such as placement of a urinary catheter, may be required.
What does it mean when you have abnormal urine?
Abnormal findings in a urine test can be characteristic of certain disease processes. For instance, persistently elevated protein in urine is a common early sign of chronic kidney disease, high levels of glucose may indicate diabetes, the detection of bacteria is often associated with a UTI, and the presence of red blood cells or abnormal cells may indicate bladder cancer.
What is urine made of?
Urine is made up of several components including water and waste materials filtered from the blood by the kidneys, as well as small numbers of cells such as epithelial cells shed from the lining of the urinary tract and possibly red and white blood cells . The type and quantity of the different components and cells contained in urine can provide important information regarding an individual’s health, which can help in the diagnosis of diseases such as bladder cancer.
What is the test used to detect RNA in urine?
In recent years there has been increasing use of molecular diagnostic tests to detect specific proteins or nucleic acids (RNA or DNA) in urine to diagnose diseases such as UTIs, prostatitis, or bladder cancer. Cxbladder, for example, measures the urine concentration of messenger RNA (mRNA) expressed by five biomarker genes to determine the presence or absence of bladder cancer.
What are the physical properties of urine?
Urine samples are routinely examined for physical properties (e.g., color, clarity, odor, density), chemical composition (e.g., pH, protein, glucose; commonly determined by a simple dipstick test) and microscopic appearance (e.g., the presence of cells, crystals, or bacteria). To detect bacteria, urine culture may also be performed, as described later.

How to test for bladder cancer?
Urinalysis: One way to test for bladder cancer is to check for blood in the urine ( hematuria ). This can be done during a urinalysis, which is a simple test to check for blood and other substances in a sample of urine. This test is sometimes done as part of a general health check-up.
What is the best test to check for bladder cancer?
Urine cytology: In this test, a microscope is used to look for cancer cells in urine. Urine cytology does find some cancers, but it’s not reliable enough to make a good screening test. Urine tests for tumor markers: Newer tests look for certain substances in urine that might be a sign of bladder cancer. These include:
Why do we need to do a bladder screening?
This is because no screening test has been shown to lower the risk of dying from bladder cancer in people who are at average risk.
What is UroVysion test?
UroVysion™: This test looks for chromosome changes that are often seen in bladder cancer cells.
What causes blood in urine?
This test is sometimes done as part of a general health check-up. Blood in the urine is usually caused by benign (non-cancer) problems, like infections, but it also can be the first sign of bladder cancer. Large amounts of blood in urine can be seen if the urine turns pink or red, but a urinalysis can find even small amounts.
What is the test that looks for mucin in urine?
ImmunoCyt™: This test looks at cells in the urine for the presence of substances such as mucin and carcinoembryonic antigen (CEA), which are often found on cancer cells.
Can urine be found with cancer?
Large amounts of blood in urine can be seen if the urine turns pink or red, but a urinalysis can find even small amounts. Urinalysis can help find some bladder cancers early, but it has not been shown to be useful as a routine screening test. Urine cytology: In this test, a microscope is used to look for cancer cells in urine.
What tests are used to check for bladder cancer?
These include the tests called NMP22 ® (or BladderChek ® ), BTA Stat ®, Immunocyt ® , and UroVysion ®, which are discussed in Can Bladder Cancer Be Found Early?
What is the best way to diagnose bladder cancer?
Cystoscopy. If bladder cancer is suspected, most doctors will recommend a cystoscopy. . A urologist uses a cystoscope, which is a long, thin, flexible tube with a light and a lens or a small video camera on the end. For details on how this procedure is done, see Cystoscopy.
What is the blue light in a cystoscopy?
Fluorescence cystoscopy (also known as blue light cystoscopy) may be done along with routine cystoscopy. For this exam, a light-activated drug is put into the bladder during cystoscopy. It’s taken up by cancer cells. When the doctor then shines a blue light through the cystoscope, any cells containing the drug will glow (fluoresce). This can help the doctor see abnormal areas that might have been missed by the white light normally used.
What is the biopsy for bladder cancer?
A biopsy is when tiny pieces (called samples) of the abnormal-looking tissue are taken out and tested for cancer cells. If bladder cancer is suspected, a biopsy is needed to be sure of the diagnosis.
What is a physical exam for bladder cancer?
A physical exam can provide information about possible signs of bladder cancer and other health problems. The doctor might do a digital rectal exam (DRE), during which a gloved, lubricated finger is put into your rectum. If you are a woman, the doctor might do a pelvic exam as well.
How long does it take for a urine culture to show up?
It can take time for the bacteria to grow, so it may take a few days to get the results of this test.
How does ultrasound help with bladder cancer?
Ultrasound uses sound waves to create pictures of internal organs. It can be useful in determining the size of a bladder cancer and whether it has spread beyond the bladder to nearby organs or tissues. It can also be used to look at the kidneys. This is usually an easy test to have, and it uses no radiation.
How to find bladder cancer?
Most doctors recommend a cystoscopy to find bladder cancer, and it’s often performed without anesthesia. During this procedure, the doctor inserts a long, thin tube with a camera into the urethra to see the inside of the bladder for growths and collect a tissue sample ( biopsy ). The tissue is studied in a lab to search for cancer and obtain more information. During a cystoscopy, doctors may also perform a fluorescence cystoscopy, or blue light cystoscopy, inserting a light-activated drug into the bladder and seeing whether any cancer cells glow when they shine a blue light through the tube.
What tests are done to check for cancer in urine?
Tests may include: Urinalysis (looks for blood in urine) Urine cytology (looks for abnormal cells in urine) Urine culture (looks for an infection, rather than cancer) For patients who have symptoms or have had bladder cancer in the past, newer tests that look for tumor markers in urine may include:
What is the procedure to remove bladder tumor?
Ultrasound uses sound waves to take pictures of the inside of the body. While working to get a full picture of the diagnosis, doctors may order a transurethral resection of bladder tumor (TURBT), which is a surgery to remove the tumor and muscle near it for testing.
What is the invasiveness of bladder cancer?
Invasiveness describes how deep the cancer is in the bladder wall, which is crucial to determining treatment. If the cancer is in the inner cell layers, it’s noninvasive or superficial. If it’s grown into deeper bladder layers or spread …
What is the first step in bladder cancer treatment?
A thorough and accurate diagnosis is the first step in developing a bladder cancer treatment plan. At Cancer Treatment Centers of America® (CTCA), our bladder cancer experts use a variety of tests and tools for diagnosing this disease and developing a customized treatment strategy for each patient. Throughout treatment, imaging and laboratory tests are used to track the size of the tumor (s), monitor the response to treatment. and modify the treatment plan when needed.
What is the blue light in a cystoscopy?
During a cystoscopy, doctors may also perform a fluorescence cystoscopy, or blue light cystoscopy, inserting a light-activated drug into the bladder and seeing whether any cancer cells glow when they shine a blue light through the tube. Doctors may also order imaging tests to see whether the cancer has spread.
What tests are used to determine if cancer has spread?
Doctors may also order imaging tests to see whether the cancer has spread. The most common imaging tests include: Magnetic resonance imaging (MRI) uses magnets and radio waves to take pictures of the inside of the body.
What is bladder cancer?
Bladder cancer is any of several types of cancer arising from the tissues of the urinary bladder. Symptoms include blood in the urine, pain with urination, and low back pain. It is caused when epithelial cells that line the bladder become malignant.
How is cancer diagnosed?
Diagnosis is typically by cystoscopy with tissue biopsies. Staging of the cancer is determined by transurethral resection and medical imaging. Treatment depends on the stage of the cancer. It may include some combination of surgery, radiation therapy, chemotherapy, or immunotherapy.
How to treat non-muscle invasive bladder cancer?
Non-muscle invasive bladder cancer (those not entering the muscle layer of the bladder) can be “shaved off” using an electrocautery device attached to a cystoscope, which in that case is called a resectoscope. The procedure is called transurethral resection of bladder tumor (TURBT) and serves primarily for pathological staging. In case of non-muscle invasive bladder cancer the TURBT is in itself the treatment, but in case of muscle invasive cancer, the procedure is insufficient for final treatment. Additionally, blue light cystoscopy with optical-imaging agent Hexaminolevulinate (HAL) is recommended at initial TURBT to increase lesion detection (especially carcinoma in situ) and improve resection quality thereby reducing recurrence. It is important to assess the quality of the resection, if there is evidence of incomplete resection or there is no muscle in the specimen (without which muscle invasiveness cannot be determined) a second TURBT is strongly recommended. Moreover, nearly half of the people with high grade non-invasive disease have residual tumor after primary TURBT, in such cases a second TURBT is important for avoiding under-staging. At this point classifying people into risk groups is recommended. Treatment and surveillance for different risk groups is indicated in the table below.
What are the risk factors for bladder cancer?
Risk factors for bladder cancer include smoking, family history, prior radiation therapy, frequent bladder infections, and exposure to certain chemicals. The most common type is transitional cell carcinoma. Other types include squamous cell carcinoma and adenocarcinoma. Diagnosis is typically by cystoscopy with tissue biopsies. Staging of the cancer is determined by transurethral resection and medical imaging.
What are the genes that cause bladder cancer?
Mutations in FGFR3, TP53, PIK3CA, KDM6A, ARID1A, KMT2D, HRAS, TERT, KRAS, CREBBP, RB1 and TSC1 genes may be associated with some cases of bladder cancer. Deletions of parts or whole of chromosome 9 is common in bladder cancer. Low grade cancer are known to harbor mutations in RAS pathway and the fibroblast growth factor receptor 3 (FGFR3) gene, both of which play a role in the MAPK/ERK pathway. p53 and RB gene mutations are implicated in high-grade muscle invasive tumors. Eighty nine percent of muscle invasive cancers have mutations in chromatin remodeling and histone modifying genes. Deletion of both copies of the GSTM1 gene has a modest increase in risk of bladder cancer. GSTM1 gene product glutathione S-transferase M1 (GSTM1) participates in the detoxification process of carcinogens such as polycyclic aromatic hydrocarbons found in cigarette smoke. Similarly, mutations in NAT2 ( N-acetyltransferase) is associated with increased risk for bladder cancer. N-acetyltransferase helps in detoxification of carcinogens like aromatic amines (also present in cigarette smoke). Various single-nucleotide polymorphisms in PSCA gene present on chromosome 8 have shown to increase the risk for bladder cancer. PSCA gene promoter region has an androgen response region. Loss of reactivity of this region to androgens is hypothesized as a cause of more number of aggressive tumors in women (unlike in men who have higher amount of androgen).
How long does it take for bladder cancer to go away?
Risk of bladder cancer decreases by 30% within 1–4 years and continues to decrease by 60% at 25 years after smoking cessation. However, former smokers will most likely always be at a higher risk of bladder cancer compared to people who have never smoked. Passive smoking also appear to be a risk.
How many cigarettes a day can you smoke to get bladder cancer?
A risk plateau at smoking about 15 cigarettes a day can be observed (meaning that those who smoke 15 cigarettes a day are approximately at the same risk as those smoking 30 cigarettes a day).
Why do we need imaging for bladder cancer?
The use of a specific imaging procedure linked to bladder cancer is dependent on a number of factors including other irregular test results, local access and availability, pre-existing medical conditions , the characteristics of a suspected tumor or unusual growth (e.g. size, location), and possible side effects of the procedure.
How does an MRI show bladder cancer?
An MRI scan uses radio waves and magnets to produce more detailed pictures of soft tissues. MRI scans can show whether bladder cancer has spread to other tissues or to the lymph nodes. To improve the quality of the images it’s sometimes necessary to administer an intravenous dye.
What is a CT scan of the kidneys, ureters and bladder called?
A CT scan of the kidneys, ureters and bladder is referred to as a CT urogram.
What is the procedure for a bladder ultrasound?
During a bladder ultrasound, the individual is often lying down while the probe is passed over the skin’s surface. A lubricating gel is administered to the skin which helps the sound waves conduct.
What is ultrasound imaging?
An ultrasound (which may also be referred to as a sonogram) uses high frequency sound waves to produce images of internal organs. Echoes, which are created as sound waves bounce off organs and tissues, produce computer images that provide information on the structure and movement of organs and the blood flow through vessels. An ultrasound does not use radiation or contrast dyes.
Can ultrasound help with bladder cancer?
An ultrasound of the urinary tract can help assess the size of a bladder tumor and whether a bladder cancer has spread. Ultrasound is able to differentiate between fluid-filled cysts and solid tumors, however, it cannot determine if a tumor is cancerous. Ultrasound can also be used to guide a biopsy needle to sample a suspected cancer.
Can imaging be used to diagnose urinary tract tumors?
Irregularities in the upper urinary tract are often assessed with imaging given its accuracy in this setting and an inability to access the region via cystoscopy. In contrast, imaging techniques are less useful for diagnosing tumors in the lower urinary tract. Small and flattened bladder tumors may also be difficult to visualize with imaging.
