Computed tomography (CT) scan It can provide precise information about the size, shape, and location of a tumor. It is also useful in checking to see if a cancer has spread to nearby lymph nodes or to organs and tissues outside the kidney.

Does Chemo work on kidney cancer?

Because kidney cancer cells usually do not respond well to chemo, chemo is not a standard treatment for kidney cancer. Some chemo drugs, such as cisplatin, 5-fluorouracil (5-FU), and gemcitabine have been shown to help a small number of patients.

What is the most common treatment for renal cell carcinoma?

Surgical resection remains the only known effective treatment for localized renal cell carcinoma, and it also is used for palliation in metastatic disease. Partial or radical nephrectomy may be used, depending on tumor and patient characteristics. Open, laparoscopic, or robotic surgical techniques may be used.

Can you see kidney cancer on a CT scan?

Sometimes people with kidney cancer do not have blood in their urine until the cancer is quite large and might have spread to other parts of the body. Imaging tests such as computed tomography (CT) scans and magnetic resonance imaging (MRI) scans can often find small kidney cancers, but these tests are expensive.

Where does kidney cancer usually spread to first?

Kidney cancer most often spreads to the lungs and bones, but it can also go to the brain, liver, ovaries, and testicles. Because it has no symptoms early on, it can spread before you even know you have it.

Imaging tests are done for a number of reasons, such as: To look at suspicious areas that might be cancer. To learn how far cancer might have spread.

Why do they do blood chemistry tests?

Blood chemistry tests: These tests are usually done in people who might have kidney cancer, because the cancer can affect the levels of certain chemicals in the blood. For example, high levels of liver enzymes are sometimes found. High blood calcium levels may be found which might lead to more imaging tests. Blood chemistry tests also measure ...

What is CBC test?

Complete blood count (CBC): This is a test that measures the number of different cells in the blood. This test result is often abnormal in people with kidney cancer. Anemia (having too few red blood cells) is very common. Less often, a person may have too many red blood cells (called polycythemia) because the kidney cancer cells make a hormone ...

Does urine show cancer?

About half of all patients with renal cell cancer will have blood in their urine. If the patient has transitional cell carcinoma (in the renal pelvis, the ureter, or the bladder), sometimes a special test of the urine sample (called urine cytology) will show actual cancer cells in the urine.

This procedure is also called nuclear magnetic resonance imaging (NMRI). Biopsy: The removal of cells or tissues so they can be viewed under a microscope by a pathologist to check for signs of cancer. To do a biopsy for renal cell cancer, a thin needle is inserted into the tumor and a sample of tissue is withdrawn.

Where are the kidneys located?

Renal cell cancer (also called kidney cancer or renal cell adenocarcinoma) is a disease in which malignant (cancer) cells are found in the lining of tubules (very small tubes) in the kidney. There are 2 kidneys, one on each side of the backbone, above the waist. Tiny tubules in the kidneys filter and clean the blood. They take out waste products and make urine. The urine passes from each kidney through a long tube called a ureter into the bladder. The bladder holds the urine until it passes through the urethra and leaves the body.

What is the best treatment for kidney cancer?

The best plan for you depends on the stage of your cancer, how healthy you are overall, and any side effects you might have. Your options may include: Surgery to remove part or all of the kidney. Biologic drugs, which boost your body’s own defenses to fight cancer cells. Drugs such as interferon -alfa or interleukin-2.

Why do people get kidney cancer?

Causes. Scientists aren’t sure exactly what causes renal cell carcinoma. They know that most kidney cancers start when something goes wrong in the genes in the kidney. No one can say for certain why that happens. Several things can raise your chances of getting the disease, like: Smoking. Being very overweight.

Does radiation kill renal cell carcinoma?

Many kinds of cancer are treated with radiation or chemotherapy, or sometimes both. These treatments usually don’t work well for renal cell carcinoma. In some cases, your doctor may still prescribe them to ease your symptoms or if other treatments haven’t worked.

What is the purpose of a nephrectomy?

Nephrectomy, when doctors remove part of one of your kidneys, or sometimes the whole kidney, to check it for renal cell carcinoma. You’ll have this test if your doctor has already spotted a tumor, but doesn’t know if it’s cancer.

How to check if liver is working?

Tests to see how well your liver is working. Ultrasound, which uses sound waves to make a picture of the organs inside your body.

Most people who have renal cell carcinoma are older, usually between ages 50 and 70. It often starts as just one tumor in a kidney, but sometimes it begins as several tumors, or it’s found in both kidneys at once. You might also hear it called renal cell cancer.

Detection and Diagnosis

Catching cancer early often allows for more treatment options. Some early cancers may have signs and symptoms that can be noticed, but that is not always the case.

Stages and Outlook (Prognosis)

After a cancer diagnosis, staging provides important information about the extent of cancer in the body and anticipated response to treatment.

Questions to Ask About Kidney Cancer

Here are some questions you can ask your cancer care team to help you better understand your cancer diagnosis and treatment options.

Which type of renal cell carcinoma is more aggressive?

Type 1 PRCC is more common and grows slowly. Type 2 PRCC is more aggressive and grows more quickly. Translocation renal cell carcinoma (TRCC) Accounts for 1% to 5% of all renal cell carcinomas and 20% of childhood caces. Tumor (s) located in the kidney. In children, TRCC usually grows slowly often without any symptoms.

What is the most common form of renal cell carcinoma?

Clear cell renal cell carcinoma, also known as ccRCC or conventional renal cell carcinoma, is a the most common form of kidney cancer. Clear cell renal cell carcinoma is named after how the tumor looks under the microscope. The cells in the tumor look clear, like bubbles.

What is the most common type of kidney cancer?

Renal cell carcinoma. Renal cell carcinoma (RCC) is the most common type of kidney cancer in adults. RCC usually starts in the lining of tiny tubes in the kidney called renal tubules. RCC often stays in the kidney, but it can spread to other parts of the body, most often the bones, lungs, or brain.

Why do you need to remove the entire kidney?

Surgery to remove an entire kidney (radical nephrectomy): Sometimes the entire kidney needs to be removed because the tumor is so large and most of the kidney has been destroyed. Your risk for kidney disease is higher if all (rather than part) of the kidney must be removed due to cancer.

Can kidney disease cause cancer?

Some studies show that people with kidney disease may have a higher risk for kidney cancer due to: Long-term dialysis: Some studies show that people on long-term dialysis have a 5-fold increased risk for kidney cancer. Experts believe this risk is due to kidney disease rather than dialysis.

Physical Examination

If you develop symptoms that are suggestive of this type of cancer (such as blood in the urine or unintentional weight loss), your healthcare provider will first ask about your symptoms and take your medical history and your family's medical history.

Labs and Tests

Several different lab tests may be ordered if your doctor suspects renal cell carcinoma. These include:

Imaging

Depending on the results of a physical examination and lab tests, imaging tests are often performed as the next step. Options include:

Biopsy

Before treatment is started, a biopsy is usually done to confirm the suspected diagnosis. This is a surgical procedure in which a sample of the tumor is removed and sent to a lab to be studied under a microscope.

Staging

Renal cell carcinoma tumors are evaluated using something called the "TNM" system. In this system, "T" stands for the tumor and has different numbers depending on the size of the tumor, "N" stands for lymph nodes, and "M"stands for metastases.

Differential Diagnosis

There are a number of conditions that may cause similar symptoms to renal cell carcinoma or a mass in the kidney on imaging. In addition, renal cell carcinoma may cause a number of symptoms not directly related to the kidneys, which has led it to be coined one of the great mimickers in medicine.

Summary

More than 50% of renal cell carcinomas are found incidentally through imaging tests for other conditions.

Staging of Kidney Cancer

When diagnosed with renal cell cancer further tests are necessary to determine the extent of spread (stage) of the cancer. Cancer’s stage is a key factor in determining the best treatment. The stage of cancer may be determined at the time of diagnosis or it may be necessary to perform additional tests.

Precision Medicine & Personalized Cancer Care

Not all kidney cancer cells are alike. They may differ from one another based on what genes have mutations that are responsible for the growth of the cancer. Testing is performed to identify genetic mutations or the proteins they produce that drive the growth of the cancer.

Stages of Renal Cell (kidney) Cancer

Staging is ultimately confirmed by surgical removal of the cancer and exploration of the area adjacent to the kidney. The following are simplified definitions of the various stages of kidney cancer. Click on a stage for an overview of the most recent information available concerning the comprehensive treatment of renal cell cancer.

What tests are done to evaluate kidney function?

In addition to a physical exam and medical history, your doctor will order some lab tests to complete your evaluation.

Microscopic tests can detect small amounts ...

What is the procedure to determine if a tumor is benign or malignant?

Biopsy Procedure. If the diagnostic test results are not clear, a biopsy may be performed. During a biopsy procedure a small sample of tissue is removed from the mass and examined to determine whether it is benign (non-cancerous) or malignant (cancerous).

What is CT scan for RCC?

A CT scan is a highly specialized x-ray that can visualize internal organs and provides a very accurate cross section picture of specific areas of the body. It is one of the primary imaging tools for assessing RCC. To enhance the image of the abdominal organs, dye may be given orally (by mouth) or intravenously (IV) before the scan. The IV dye (also called IV contrast) may cause a hot flushing sensation or an allergic reaction, especially in individuals who are allergic to iodine.

What is a bone scan?

Bone Scan. A bone scan is used to check for the spread of cancer to the bones. It is done by injecting small amounts of a special radioactive material through a vein into your bloodstream. The test can identify both cancerous and non-cancerous diseases.

What is the purpose of a chest xray?

A plain x-ray of the chest may be done to see if the cancer has spread to the lungs. If something notable is seen on the x-ray, the doctor may order a CT scan of the chest to help determine what it is.

Why do we collect blood samples for a physical exam?

Blood samples will be collected as a part of a routine physical exam to evaluate kidney function and overall health.

Can a biopsy be taken from a kidney?

If there is clear evidence of widespread metastasis when the kidney mass is discovered, a biopsy may be taken from an area of metastasis instead of from the kidney.

What test is done to check for kidney cancer?

Lab Tests. The diagnostic work-up of a possible kidney cancer often begins with a urinalysis, a test done not to only to look for blood in your urine, but signs of infection, protein, and more. 5 Roughly half of people with kidney cancer will have some amount of blood in their urine.

How to diagnose renal cell carcinoma?

Kidney cancer (renal cell carcinoma) 1 is usually diagnosed using a combination of ultrasound, CT, and MRI scans, along with a careful history, physical exam, blood tests, and urine tests. Once a cancer is diagnosed, the tumor needs to be carefully staged in order to determine the most appropriate treatments.

What is the name of the test that involves inserting a lighted catheter into the bladder, through the ure

Cystoscopy and Nephro-Ureteroscopy. These tests involved inserting a lighted catheter into the bladder, through the ureter, and up to the renal pelvis (the "center" of the kidney). 15  It is used primarily if there is also a mass in the bladder or ureter, such as transitional cell carcinoma.

What is angiography done with?

Angiography is often done in combination with a CT scan and involves injecting a dye into the renal artery to define the blood vessels of the kidney. 14  This test is sometimes used to help plan for surgery for a tumor.

Can you get a CT scan without contrast?

A CT scan is usually done first without contrast, and then with a radiocontrast dye. The dye can sometimes pose concern for people who have kidney dysfunction, in which case a different imaging test may be used. 9

What is the purpose of a CT scan for kidney cancer?

CT scans use a series of X-rays to give a cross-sectional picture of a region of the body such as the kidney. 8 In addition to defining a kidney cancer, a CT scan can give important information for staging by evaluating whether it appears that the cancer has spread outside of the kidney or to lymph nodes.

Can kidney cancer cause elevated liver function?

Kidney cancer is also unique in that it can cause elevations in liver function tests, even without the cancer spreading to the liver. This sign is one of the paraneoplastic syndromes that can occur when these tumor cells secrete substances or hormones. 6 Paraneoplastic signs may also include an elevated calcium level in the blood ( hypercalcemia ), though this may also occur when the cancer spreads to bones.

Treatment

• Kidney cancer treatment usually begins with surgery to remove the cancer. For cancers confined to the kidney, this may be the only treatment needed. If the cancer has spread beyond the kidney, additional treatments may be recommended. Together, you and your treatment team can discus…
