Renal Cell Cancer Treatment (PDQ®): Treatment - Patient Information [NCI]

General Information About Renal Cell Cancer

Renal cell cancer is a disease in which malignant (cancer) cells form in tubules of the kidney.

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.

An inset shows the renal tubules and urine. Also shown are the prostate and penis (left panel) and the uterus (right panel). Urine is made in the renal tubules and collects in the renal pelvis of each kidney. The urine flows from the kidneys through the ureters to the bladder. The urine is stored in the bladder until it leaves the body through the urethra.

Cancer that starts in the ureters or the renal pelvis (the part of the kidney that collects urine and drains it to the ureters) is different from renal cell cancer. For more information, see Transitional Cell Cancer of the Renal Pelvis and Ureter Treatment.

Smoking and misuse of certain pain medicines can affect the risk of renal cell cancer.

Anything that increases your risk of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesn't mean that you will not get cancer. Talk with your doctor if you think you may be at risk.

Risk factors for renal cell cancer include the following:

• Smoking.
• Misusing certain pain medicines, including over-the-counter pain medicines, for a long time.
• Being overweight.
• Having high blood pressure.
• Having a family history of renal cell cancer.
• Having certain genetic conditions, such as von Hippel-Lindau disease or hereditary papillary renal cell carcinoma.

Signs of renal cell cancer include blood in the urine and a lump in the abdomen.

These and other signs and symptoms may be caused by renal cell cancer or by other conditions. There may be no signs or symptoms in the early stages. Signs and symptoms may appear as the tumor grows. Check with your doctor if you have any of the following:

• Blood in the urine.
• A lump in the abdomen.
• A pain in the side that doesn't go away.
• Loss of appetite.
• Weight loss for no known reason.
• Anemia.

Tests that examine the abdomen and kidneys are used to diagnose renal cell cancer.

The following tests and procedures may be used:

• Physical exam and health history: An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patient's health habits and past illnesses and treatments will also be taken.
• Ultrasound exam: A procedure in which high-energy sound waves (ultrasound) are bounced off internal tissues or organs and make echoes. The echoes form a picture of body tissues called a sonogram.
• Blood chemistry studies: A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by organs and tissues in the body. An unusual (higher or lower than normal) amount of a substance can be a sign of disease.
• Urinalysis: A test to check the color of urine and its contents, such as sugar, protein, red blood cells, and white blood cells.
• CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, such as the abdomen and pelvis, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography.
• MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. 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. A biopsy may not be needed if the imaging test results provide enough information to make a diagnosis.

Certain factors affect prognosis (chance of recovery) and treatment options.

The prognosis and treatment options depend on the following:

• The stage of the disease.
• The patient's age and general health.

Stages of Renal Cell Cancer

After renal cell cancer has been diagnosed, tests are done to find out if cancer cells have spread within the kidney or to other parts of the body.

The process used to find out if cancer has spread within the kidney or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. It is important to know the stage in order to plan treatment. The following tests and procedures may be used in the staging process:

• CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, such as the chest or brain, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography.
• MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body, such as the brain. This procedure is also called nuclear magnetic resonance imaging (NMRI).
• Chest x-ray: An x-ray of the organs and bones inside the chest. An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body.
• Bone scan: A procedure to check if there are rapidly dividing cells, such as cancer cells, in the bone. A very small amount of radioactive material is injected into a vein and travels through the bloodstream. The radioactive material collects in the bones with cancer and is detected by a scanner.

There are three ways that cancer spreads in the body.

Cancer can spread through tissue, the lymph system, and the blood:

• Tissue. The cancer spreads from where it began by growing into nearby areas.
• Lymph system. The cancer spreads from where it began by getting into the lymph system. The cancer travels through the lymph vessels to other parts of the body.
• Blood. The cancer spreads from where it began by getting into the blood. The cancer travels through the blood vessels to other parts of the body.

Cancer may spread from where it began to other parts of the body.

When cancer spreads to another part of the body, it is called metastasis. Cancer cells break away from where they began (the primary tumor) and travel through the lymph system or blood.

• Lymph system. The cancer gets into the lymph system, travels through the lymph vessels, and forms a tumor (metastatic tumor) in another part of the body.
• Blood. The cancer gets into the blood, travels through the blood vessels, and forms a tumor (metastatic tumor) in another part of the body.

The metastatic tumor is the same type of cancer as the primary tumor. For example, if renal cell cancer spreads to the bone, the cancer cells in the bone are actually cancerous renal cells. The disease is metastatic renal cell cancer, not bone cancer.

The following stages are used for renal cell cancer:

Stage I

Stage I kidney cancer. The tumor is 7 centimeters or smaller and is found in the kidney only.

In stage I, the tumor is 7 centimeters or smaller and is found in the kidney only.

Stage II

Stage II kidney cancer. The tumor is larger than 7 centimeters and is found in the kidney only.

In stage II, the tumor is larger than 7 centimeters and is found in the kidney only.

Stage III

Stage III kidney cancer. The cancer in the kidney is any size and cancer has spread to a) nearby lymph nodes, b) the blood vessels in or near the kidney (renal vein or vena cava), c) the structures in the kidney that collect urine, or d) the layer of fatty tissue around the kidney.

In stage III, one of the following is found:

• the cancer in the kidney is any size, and cancer has spread to nearby lymph nodes; or
• cancer has spread to blood vessels in or near the kidney (renal vein or vena cava), to the fat around the structures in the kidney that collect urine, or to the layer of fatty tissue around the kidney. Cancer may have spread to nearby lymph nodes.

Stage IV

Stage IV kidney cancer. Cancer has spread a) beyond the layer of fatty tissue around the kidney and may have spread into the adrenal gland above the kidney with cancer or to nearby lymph nodes, or b) to other parts of the body, such as the brain, lung, liver, adrenal gland, bone, or distant lymph nodes.

In stage IV, one of the following is found:

• cancer has spread beyond the layer of fatty tissue around the kidney and may have spread into the adrenal gland above the kidney with cancer or to nearby lymph nodes; or
• cancer has spread to other parts of the body, such as the bones, liver, lungs, brain, adrenal glands, or distant lymph nodes.

Renal cell cancer can recur (come back) many years after initial treatment.

The cancer may come back in the kidney or in other parts of the body.

Treatment Option Overview

There are different types of treatment for patients with renal cell cancer.

Different types of treatments are available for patients with renal cell cancer. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.

The following types of treatment are used:

Surgery

Surgery to remove part or all of the kidney is often used to treat renal cell cancer. The following types of surgery may be used:

• Partial nephrectomy: A surgical procedure to remove the cancer within the kidney and some of the tissue around it. A partial nephrectomy may be done to prevent loss of kidney function when the other kidney is damaged or has already been removed.
• Simple nephrectomy: A surgical procedure to remove the kidney only.
• Radical nephrectomy: A surgical procedure to remove the kidney, the adrenal gland, surrounding tissue, and, usually, nearby lymph nodes.

A person can live with part of 1 working kidney, but if both kidneys are removed or not working, the person will need dialysis (a procedure to clean the blood using a machine outside of the body) or a kidney transplant (replacement with a healthy donated kidney). A kidney transplant may be done when the disease is in the kidney only, and a donated kidney can be found. If the patient has to wait for a donated kidney, other treatment is given as needed.

When surgery to remove the cancer is not possible, a treatment called arterial embolization may be used to shrink the tumor. A small incision is made, and a catheter (thin tube) is inserted into the main blood vessel that flows to the kidney. Small pieces of a special gelatin sponge are injected through the catheter into the blood vessel. The sponges block the blood flow to the kidney and prevent the cancer cells from getting oxygen and other substances they need to grow.

After the doctor removes all the cancer that can be seen at the time of the surgery, some patients may be given chemotherapy or radiation therapy after surgery to kill any cancer cells that are left. Treatment given after the surgery, to lower the risk that the cancer will come back, is called adjuvant therapy.

Radiation therapy

Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. External radiation therapy uses a machine outside the body to send radiation toward the area of the body with cancer. External radiation therapy is used to treat renal cell cancer, and may also be used as palliative therapy to relieve symptoms and improve quality of life.

Chemotherapy

Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy).

For more information, see Drugs Approved for Kidney (Renal Cell) Cancer.

Immunotherapy

Immunotherapy is a treatment that uses the patient's immune system to fight cancer. Substances made by the body or made in a laboratory are used to boost, direct, or restore the body's natural defenses against cancer.

The following types of immunotherapy are being used in the treatment of renal cell cancer:

• Immune checkpoint inhibitor therapy: Some types of immune cells, such as T cells, and some cancer cells have certain proteins, called checkpoint proteins, on their surface that keep immune responses in check. When cancer cells have large amounts of these proteins, they will not be attacked and killed by T cells. Immune checkpoint inhibitors block these proteins and the ability of T cells to kill cancer cells is increased. They are used to treat some patients with advanced renal cell cancer that cannot be removed by surgery.

  There are two types of immune checkpoint inhibitor therapy:

  • CTLA-4 inhibitor therapy: CTLA-4 is a protein on the surface of T cells that helps keep the body's immune responses in check. When CTLA-4 attaches to another protein called B7 on a cancer cell, it stops the T cell from killing the cancer cell. CTLA-4 inhibitors attach to CTLA-4 and allow the T cells to kill cancer cells. Ipilimumab is a type of CTLA-4 inhibitor.
    
    Immune checkpoint inhibitor. Checkpoint proteins, such as B7-1/B7-2 on antigen-presenting cells (APC) and CTLA-4 on T cells, help keep the body's immune responses in check. When the T-cell receptor (TCR) binds to antigen and major histocompatibility complex (MHC) proteins on the APC and CD28 binds to B7-1/B7-2 on the APC, the T cell can be activated. However, the binding of B7-1/B7-2 to CTLA-4 keeps the T cells in the inactive state so they are not able to kill tumor cells in the body (left panel). Blocking the binding of B7-1/B7-2 to CTLA-4 with an immune checkpoint inhibitor (anti-CTLA-4 antibody) allows the T cells to be active and to kill tumor cells (right panel).
  • PD-1 and PD-L1 inhibitor therapy: PD-1 is a protein on the surface of T cells that helps keep the body's immune responses in check. PD-L1 is a protein found on some types of cancer cells. When PD-1 attaches to PD-L1, it stops the T cell from killing the cancer cell. PD-1 and PD-L1 inhibitors keep PD-1 and PD-L1 proteins from attaching to each other. This allows the T cells to kill cancer cells. Nivolumab and pembrolizumab are types of PD-1 inhibitors. Avelumab is a type of PD-L1 inhibitor.

Immune checkpoint inhibitor. Checkpoint proteins, such as PD-L1 on tumor cells and PD-1 on T cells, help keep immune responses in check. The binding of PD-L1 to PD-1 keeps T cells from killing tumor cells in the body (left panel). Blocking the binding of PD-L1 to PD-1 with an immune checkpoint inhibitor (anti-PD-L1 or anti-PD-1) allows the T cells to kill tumor cells (right panel).

• Interferon: Interferon affects the division of cancer cells and can slow tumor growth.
• Interleukin-2 (IL-2): IL-2 boosts the growth and activity of many immune cells, especially lymphocytes (a type of white blood cell). Lymphocytes can attack and kill cancer cells.

For more information, see Drugs Approved for Kidney (Renal Cell) Cancer.

Targeted therapy

Targeted therapy is a type of treatment that uses drugs or other substances to identify and attack specific cancer cells. Targeted therapy with antiangiogenic agents are used to treat advanced renal cell cancer. Antiangiogenic agents keep blood vessels from forming in a tumor, causing the tumor to starve and stop growing or to shrink.

Monoclonal antibodies and kinase inhibitors are two types of antiangiogenic agents used to treat renal cell cancer.

• Monoclonal antibodies are immune system proteins made in the laboratory to treat many diseases, including cancer. As a cancer treatment, these antibodies can attach to a specific target on cancer cells or other cells that may help cancer cells grow. The antibodies are able to then kill the cancer cells, block their growth, or keep them from spreading. Monoclonal antibodies are given by infusion. They may be used alone or to carry drugs, toxins, or radioactive material directly to cancer cells. Monoclonal antibodies used to treat renal cell cancer attach to and block substances that cause new blood vessels to form in tumors. Bevacizumab is a monoclonal antibody.monoclonal antibodies: how monoclonal antibodies treat cancerHow do monoclonal antibodies work to treat cancer? This video shows how monoclonal antibodies, such as trastuzumab, pembrolizumab, and rituximab, block molecules cancer cells need to grow, flag cancer cells for destruction by the body's immune system, or deliver harmful substances to cancer cells.
• Kinase inhibitors stop cells from dividing and may prevent the growth of new blood vessels that tumors need to grow.

  Vascular endothelial growth factor (VEGF) inhibitors and mTOR inhibitors are kinase inhibitors used to treat renal cell cancer.

  • VEGF inhibitors: Cancer cells make a substance called VEGF, which causes new blood vessels to form (angiogenesis) and helps the cancer grow. VEGF inhibitors block VEGF and stop new blood vessels from forming. This may kill cancer cells because they need new blood vessels to grow. Sunitinib, pazopanib, cabozantinib, axitinib, sorafenib, lenvatinib, and tivozanib are VEGF inhibitors.
  • mTOR inhibitors: mTOR is a protein that helps cells divide and survive. mTOR inhibitors block mTOR and may keep cancer cells from growing and prevent the growth of new blood vessels that tumors need to grow. Everolimus and temsirolimus are mTOR inhibitors.

For more information, see Drugs Approved for Kidney (Renal Cell) Cancer.

New types of treatment are being tested in clinical trials.

Information about clinical trials is available from the NCI website.

Treatment for renal cell cancer may cause side effects.

For information about side effects caused by treatment for cancer, visit our Side Effects page.

Patients may want to think about taking part in a clinical trial.

For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment.

Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment.

Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward.

Patients can enter clinical trials before, during, or after starting their cancer treatment.

Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment.

Clinical trials are taking place in many parts of the country. Information about clinical trials supported by NCI can be found on NCI's clinical trials search webpage. Clinical trials supported by other organizations can be found on the ClinicalTrials.gov website.

Follow-up tests may be needed.

As you go through treatment, you will have follow-up tests or check-ups. Some tests that were done to diagnose or stage the cancer may be repeated to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests.

Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back).

About This PDQ Summary

About PDQ

Physician Data Query (PDQ) is the National Cancer Institute's (NCI's) comprehensive cancer information database. The PDQ database contains summaries of the latest published information on cancer prevention, detection, genetics, treatment, supportive care, and complementary and alternative medicine. Most summaries come in two versions. The health professional versions have detailed information written in technical language. The patient versions are written in easy-to-understand, nontechnical language. Both versions have cancer information that is accurate and up to date and most versions are also available in Spanish.

PDQ is a service of the NCI. The NCI is part of the National Institutes of Health (NIH). NIH is the federal government's center of biomedical research. The PDQ summaries are based on an independent review of the medical literature. They are not policy statements of the NCI or the NIH.

Purpose of This Summary

This PDQ cancer information summary has current information about the treatment of renal cancer. It is meant to inform and help patients, families, and caregivers. It does not give formal guidelines or recommendations for making decisions about health care.

Reviewers and Updates

Editorial Boards write the PDQ cancer information summaries and keep them up to date. These Boards are made up of experts in cancer treatment and other specialties related to cancer. The summaries are reviewed regularly and changes are made when there is new information. The date on each summary ("Updated") is the date of the most recent change.

The information in this patient summary was taken from the health professional version, which is reviewed regularly and updated as needed, by the PDQ Adult Treatment Editorial Board.

Clinical Trial Information

A clinical trial is a study to answer a scientific question, such as whether one treatment is better than another. Trials are based on past studies and what has been learned in the laboratory. Each trial answers certain scientific questions in order to find new and better ways to help cancer patients. During treatment clinical trials, information is collected about the effects of a new treatment and how well it works. If a clinical trial shows that a new treatment is better than one currently being used, the new treatment may become "standard." Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.

Clinical trials can be found online at NCI's website. For more information, call the Cancer Information Service (CIS), NCI's contact center, at 1-800-4-CANCER (1-800-422-6237).
