Stages of Wilms Tumor and Other Childhood Kidney Tumors
Treatment(Wilms Tumor and Other Childhood Kidney Tumors)
There are two kidneys, one on each side of the spine, above the waist. The kidneys clean the blood to take out waste and make urine. Urine collects in the renal pelvis, the area at the center of the kidney, and then passes through the ureter, into the bladder, and out of the body. The kidneys also make hormones that help control blood pressure and signal the bone marrow to make red blood cells when needed.
There are three main types of kidney cancer. Renal cell cancer is the most common type in adults and Wilms tumors are the most common in children. These types form in the tissues of the kidney that make urine. Transitional cell cancer forms in the renal pelvis and ureter in adults.
Smoking and taking certain pain medicines for a long time can increase the risk of adult kidney cancer. Certain inherited disorders can increase the risk of kidney cancer in children and adults. These include von Hippel-Lindau syndrome, hereditary leiomyomatosis and renal cell cancer, Birt-Hogg-Dube syndrome, and hereditary papillary renal cancer.
Kidney tumors may be benign or malignant.
Renal cell cancer (also called kidney cancer or renal 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.
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. (See the PDQ summary about Transitional Cell Cancer of the Renal Pelvis and Ureter Treatment for more information).
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:
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:
The following tests and procedures may be used:
The prognosis (chance of recovery) and treatment options depend on the following:
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:
Cancer can spread through tissue, the lymph system, and the blood:
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.
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.
In stage I, the tumor is 7 centimeters or smaller and is found only in the kidney.
In stage II, the tumor is larger than 7 centimeters and is found only in the kidney.
In stage III:
In stage IV, cancer has spread:
Recurrent renal cell cancer is cancer that has recurred (come back) after it has been treated. The cancer may come back many years after initial treatment, in the kidney or in other parts of the body.
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.
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:
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.
Even if 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 is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy:
The way the radiation therapy is given depends on the type and stage of the cancer being treated. 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 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). When chemotherapy is placed directly into the cerebrospinal fluid, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). The way the chemotherapy is given depends on the type and stage of the cancer being treated.
See Drugs Approved for Kidney (Renal Cell) Cancer for more information.
Biologic therapy 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. This type of cancer treatment is also called biotherapy or immunotherapy. The following types of biologic therapy are being used or studied in the treatment of renal cell cancer:
See Drugs Approved for Kidney (Renal Cell) Cancer for more information.
Targeted therapy uses drugs or other substances to identify and attack specific cancer cells without harming normal 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 antibody therapy uses antibodies made in the laboratory, from a single type of immune system cell. These antibodies can identify substances on cancer cells or normal substances that may help cancer cells grow. The antibodies attach to the substances and 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.
Kinase inhibitors stop cells from dividing and may prevent the growth of new blood vessels that tumors need to grow. An mTOR inhibitor is a type of kinase inhibitor. Everolimus and temsirolimus are mTOR inhibitors used to treat advanced renal cell cancer.
See Drugs Approved for Kidney (Renal Cell) Cancer for more information.
Information about clinical trials is available from the NCI website.
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.
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. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials.
Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order 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). These tests are sometimes called follow-up tests or check-ups.
Treatment of stage I renal cell cancer may include the following:
Check the list of NCI-supported cancer clinical trials that are now accepting patients with stage I renal cell cancer. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. Talk with your doctor about clinical trials that may be right for you. General information about clinical trials is available from the NCI website.
Treatment of stage II renal cell cancer may include the following:
Check the list of NCI-supported cancer clinical trials that are now accepting patients with stage II renal cell cancer. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug.

Treatment of stage III renal cell cancer may include the following:
Check the list of NCI-supported cancer clinical trials that are now accepting patients with stage III renal cell cancer. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. Talk with your doctor about clinical trials that may be right for you. General information about clinical trials is available from the NCI website.
Treatment of stage IV and recurrent renal cell cancer may include the following:
The renal pelvis is the top part of the ureter. The ureter is a long tube that connects the kidney to the bladder. There are two kidneys, one on each side of the backbone, above the waist. The kidneys of an adult are about 5 inches long and 3 inches wide and are shaped like a kidney bean. Tiny tubules in the kidneys filter and clean the blood. They take out waste products and make urine. The urine collects in the middle of each kidney in the renal pelvis. Urine passes from the renal pelvis through the ureter into the bladder. The bladder holds the urine until it passes through the urethra and leaves the body.
The renal pelvis and ureters are lined with transitional cells. These cells can change shape and stretch without breaking apart. Transitional cell cancer starts in these cells. Transitional cell cancer can form in the renal pelvis or the ureter or both.
Renal cell cancer is a more common type of kidney cancer. See the PDQ summary about Renal Cell Cancer Treatment for more information.
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 transitional cell cancer of the renal pelvis and ureter include the following:
These and other signs and symptoms may be caused by transitional cell cancer of the renal pelvis and ureter 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:
The following tests and procedures may be used:
The prognosis (chance of recovery) depends on the stage and grade of the tumor.
The treatment options depend on the following:
Most transitional cell cancer of the renal pelvis and ureter can be cured if found early.
The process used to find out if cancer has spread within the renal pelvis and ureter 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:
Cancer can spread through tissue, the lymph system, and the blood:
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.
The metastatic tumor is the same type of cancer as the primary tumor. For example, if transitional cell cancer of the ureter spreads to the lung, the cancer cells in the lung are actually ureter cancer cells. The disease is metastatic cancer of the ureter, not lung cancer.
In stage 0, abnormal cells are found in tissue lining the inside of the renal pelvis or ureter. These abnormal cells may become cancer and spread into nearby normal tissue. Stage 0 is divided into stage 0a and stage 0is, depending on the type of tumor:
In stage I, cancer has formed and spread through the lining of the renal pelvis and/or ureter, into the layer of connective tissue.
In stage II, cancer has spread through the layer of connective tissue to the muscle layer of the renal pelvis and/or ureter.
In stage III, cancer has spread:
In stage IV, cancer has spread to at least one of the following:
The cancer is found only in the kidney.
The cancer has spread to tissues around the kidney and to nearby lymph nodes and blood vessels in the pelvis.
The cancer ha

s spread to other parts of the body.
Recurrent transitional cell cancer of the renal pelvis and ureter is cancer that has recurred (come back) after it has been treated. The cancer may come back in the renal pelvis, ureter, or other parts of the body.
Different types of treatments are available for patients with transitional cell cancer of the renal pelvis and ureter. 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.
One of the following surgical procedures may be used to treat transitional cell cancer of the renal pelvis and ureter:
This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI Web site.
Fulguration is a surgical procedure that destroys tissue using an electric current. A tool with a small wire loop on the end is used to remove the cancer or to burn away the tumor with electricity.
This is a surgical procedure to remove localized cancer from the renal pelvis without removing the entire kidney. Segmental resection may be done to save kidney function when the other kidney is damaged or has already been removed.
A laser beam (narrow beam of intense light) is used as a knife to remove the cancer. A laser beam can also be used to kill the cancer cells. This procedure may also be called or laser fulguration.
Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping the cells from dividing. Biologic therapy 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. Regional treatment means the anticancer drugs or biologic substances are placed directly into an organ or a body cavity such as the abdomen, so the drugs will affect cancer cells in that area. Clinical trials are studying chemotherapy or biologic therapy using drugs placed directly into the renal pelvis or the ureter.

For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. Talk with your doctor about clinical trials that may be right for you. General information about clinical trials is available from the NCI website.
Treatment of regional transitional cell cancer of the renal pelvis and ureter is usually done in a clinical trial.

There are two 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.
In Wilms tumor, one or more tumors may be found in one or both kidneys. Wilms tumor may spread to the lungs, liver, bone, brain, or nearby lymph nodes. In children and adolescents younger than 15 years old, most kidney cancers are Wilms tumors.
Renal cell cancer is rare in children and adolescents younger than 15 years old. It is much more common in adolescents between 15 and 19 years old. Children and adolescents are more likely to be diagnosed with a large renal cell tumor or cancer that has spread. Renal cell cancers may spread to the lungs, liver, or lymph nodes. Renal cell cancer may also be called renal cell carcinoma.
Rhabdoid tumor of the kidney is a type of kidney cancer that occurs mostly in infants and young children. It is often advanced at the time of diagnosis. Rhabdoid tumor of the kidney grows and spreads quickly, often to the lungs or brain.
Children with a certain change in the SMARCB1 gene are checked regularly to see if a rhabdoid tumor has formed in the kidney or has spread to the brain:
Clear cell sarcoma of the kidney is a type of kidney tumor that may spread to the lung, bone, brain, or soft tissue. When it recurs (comes back) after treatment, it often recurs in the brain or lung.
Congenital mesoblastic nephroma is a tumor of the kidney that is often diagnosed during the first year of life. It can usually be cured.
Ewing sarcoma (previously called neuroepithelial tumor) of the kidney is rare and usually occurs in young adults. These tumors grow and spread to other parts of the body quickly.
Primary renal myoepithelial carcinoma is a rare type of cancer that usually affects soft tissues, but sometimes forms in the internal organs (such as the kidney). This type of cancer grows and spreads quickly.
Cystic partially differentiated nephroblastoma is a very rare type of Wilms tumor made up of cysts.
Multilocular cystic nephromas are benign tumors made up of cysts and are most common in infants, young children, and adult women. These tumors can occur in one or both kidneys.
Children with this type of tumor also may have pleuropulmonary blastoma, so imaging tests that check the lungs for cysts or solid tumors are done. Since multilocular cystic nephroma may be an inherited condition, genetic counseling and genetic testing may be considered. See the PDQ summary about Unusual Cancers of Childhood Treatment for more information about pleuropulmonary blastoma.
Primary renal synovial sarcoma is a cyst-like tumor of the kidney and is most common in young adults. These tumors grow and spread quickly.
Anaplastic sarcoma of the kidney is a rare tumor that is most common in children or adolescents younger than 15 years of age. Anaplastic sarcoma of the kidney often spreads to the lungs, liver, or bones. Imaging tests that check the lungs for cysts or solid tumors may be done. Since anaplastic sarcoma may be an inherited condition, genetic counseling and genetic testing may be considered.
Sometimes, after the kidneys form in the fetus, abnormal groups of kidney cells remain in one or both kidneys. In nephroblastomatosis (diffuse hyperplastic perilobar nephroblastomatosis), these abnormal groups of cells may grow in many places inside the kidney or make a thick layer around the kidney. When these groups of abnormal cells are found in a kidney after it was removed for Wilms tumor, the child has an increased risk of Wilms tumor in the other kidney. Frequent follow-up testing is important at least every 3 months, for at least 7 years after the child is treated.
Anything that increases the 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 to your child's doctor if you think your child may be at risk.
Wilms tumor may be part of a genetic syndrome that affects growth or development. A genetic syndrome is a set of signs and symptoms or conditions that occur together and is caused by certain changes in the genes. Certain conditions can also increase a child's risk of developing Wilms tumor. These and other genetic syndromes and conditions have been linked to Wilms tumor:
Screening tests are done in children with an increased risk of Wilms tumor. These tests may help find cancer early and decrease the chance of dying from cancer.
In general, children with an increased risk of Wilms tumor should be screened for Wilms tumor every three months until they are at least 8 years old. An ultrasound test of the abdomen is usually used for screening. Small Wilms tumors may be found and removed before symptoms occur.
Children with Beckwith-Wiedemann syndrome or hemihyperplasia are also screened for liver and adrenal tumors that are linked to these genetic syndromes. A test to check the alpha-fetoprotein (AFP) level in the blood and an ultrasound of the abdomen are done until the child is 4 years old. An ultrasound of the kidneys is done after the child is 4 years old. In children with certain gene changes, a different schedule for ultrasound of the abdomen may be used.
Children with aniridia and a certain gene change are screened for Wilms tumor every three months until they are 8 years old. An ultrasound test of the abdomen is used for screening.
Some children develop Wilms tumor in both kidneys. These often appear when Wilms tumor is first diagnosed, but Wilms tumor may also occur in the second kidney after the child is successfully treated for Wilms tumor in one kidney. Children with an increased risk of a second Wilms tumor in the other kidney should be screened for Wilms tumor every three months for up to eight years. An ultrasound test of the abdomen may be used for screening.
Renal cell cancer may be related to the following conditions:
Prior chemotherapy or radiation therapy for a childhood cancer, such as neuroblastoma, soft tissue sarcoma, leukemia, or Wilms tumor may also increase the risk of renal cell cancer. See the Second Cancers section in the PDQ summary about Late Effects of Treatment for Childhood Cancer for more information.
Genetic counseling (a discussion with a trained professional about genetic diseases and whether genetic testing is needed) may be needed if the child has one of the following syndromes or conditions:
Sometimes childhood kidney tumors do not cause signs and symptoms and the parent finds a mass in the abdomen by chance or the mass is found during a well-child health check up. These and other signs and symptoms may be caused by kidney tumors or by other conditions. Check with your child's doctor if your child has any of the following:
Wilms tumor that has spread to the lungs or liver may cause the following signs and symptoms:
The following tests and procedures may be used:
The prognosis (chance of recovery) and treatment options for Wilms tumor depend on the following:
The prognosis for renal cell cancer depends on the following:
The prognosis for rhabdoid tumor of the kidney depends on the following:
The prognosis for clear cell sarcoma of the kidney depends on the following:
The process used to find out if cancer has spread outside of the kidney 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 doctor will use results of the diagnostic and staging tests to help find out the stage of the disease.
The following tests may be done to see if cancer has spread to other places in the body:
Cancer can spread through tissue, the lymph system, and the blood:
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.
The metastatic tumor is the same type of cancer as the primary tumor. For example, if Wilms tumor spreads to the lung, the cancer cells in the lung are actually Wilms tumor cells. The disease is metastatic Wilms tumor, not lung cancer.
The histology (how the cells look under a microscope) of the tumor affects the prognosis and the treatment of Wilms tumor. The histology may be favorable or anaplastic (unfavorable). Tumors with a favorable histology have a better prognosis and respond better to chemotherapy than anaplastic tumors. Tumor cells that are anaplastic divide quickly and under a microscope do not look like the type of cells they came from. Anaplastic tumors are harder to treat with chemotherapy than other Wilms tumors at the same stage.
In stage I, the tumor was completely removed by surgery and all of the following are true:
In stage II, the tumor was completely removed by surgery and no cancer cells were found at the edges of the area where the cancer was removed. Cancer has not spread to lymph nodes. Before the tumor was removed, one of the following was true:
In stage III, cancer remains in the abdomen after surgery and one of the following may be true:
In stage IV, cancer has spread through the blood to organs such as the lungs, liver, bone, or brain, or to lymph nodes outside of the abdomen and pelvis.
In stage
V, cancer
cells
are found in both kidneys
when the cancer is first diagnosed.
Recurrent cancer is cancer that has recurred (come back) after it has been treated.
Different types of treatment are available for children with Wilms and other childhood kidney tumors. 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.
Because cancer in children is rare, taking part in a clinical trial should be considered. Some clinical trials are open only to patients who have not started treatment.
Your child's treatment will be overseen by a pediatric oncologist, a doctor who specializes in treating children with cancer. The pediatric oncologist works with other pediatric health care providers who are experts in treating children with Wilms tumor or other childhood kidney tumors and who specialize in certain areas of medicine. These may include the following specialists:
Side effects from cancer treatment that begin during or after treatment and continue for months or years are called late effects. Late effects of cancer treatment may include the following:
Some late effects may be treated or controlled. It is important to talk with your child's doctors about the effects cancer treatment can have on your child. (See the PDQ summary about Late Effects of Treatment for Childhood Cancer for more information).
Clinical trials are being done to find out if lower doses of chemotherapy and radiation can be used to lessen the late effects of treatment without changing how well the treatment works.
Two types of surgery are used to treat kidney tumors:
Even if 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 of the cancer coming back, is called adjuvant therapy. Sometimes, a second-look surgery is done to see if cancer remains after chemotherapy or 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. There are two types of radiation therapy:
The way the radiation therapy is given depends on the type and stage of the cancer being treated and whether a biopsy was done before surgery to remove the tumor. External radiation therapy is used to treat Wilms tumor and other childhood kidney tumors.
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). When chemotherapy is placed directly into the cerebrospinal fluid, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). Combination chemotherapy is treatment using two or more anticancer drugs.
The way the chemotherapy is given depends on the type and stage of the cancer being treated. Systemic chemotherapy is used to treat Wilms tumor and other childhood kidney tumors.
Sometimes the tumor cannot be removed by surgery for one of the following reasons:
In this case, a biopsy is done first. Then chemotherapy is given to reduce the size of the tumor before surgery, in order to save as much healthy tissue as possible and lessen problems after surgery. This is called neoadjuvant chemotherapy. Radiation therapy is given after surgery.
See Drugs Approved for Wilms Tumor and Other Childhood Kidney Cancers for more information.
Biologic therapy 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. This type of cancer treatment is also called biotherapy or immunotherapy.
Interferon and interleukin-2 (IL-2) are types of biologic therapy used to treat childhood renal cell cancer. Interferon affects the division of cancer cells and can slow tumor growth. 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.
High-dose chemotherapy with stem cell rescue is a method of giving high doses of chemotherapy and replacing blood -forming cells destroyed by the cancer treatment. Stem cells (immature blood cells) are removed from the blood or bone marrow of the patient or a donor and are frozen and stored. After the chemotherapy is completed, the stored stem cells are thawed and given back to the patient through an infusion. These re-infused stem cells grow into (and restore) the body's blood cells.
High-dose chemotherapy with stem cell rescue may be used to treat recurrent Wilms tumor.
Information about clinical trials is available from the NCI website.
Targeted therapy is a treatment that uses drugs or other substances to identify and attack specific cancer cells without harming normal cells. Targeted therapy used to treat childhood kidney tumors may include the following:
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.
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. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials.
Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order 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.

will continue to be done from time to time after treatment has ended.
The results of these tests can show if your child's condition
has changed or if the cancer has recurred
(come back). These tests are sometimes called follow-up
tests or check-ups.
