Question: What is (are) Renal Cell Cancer ?
Answer: Key Points - Renal cell cancer is a disease in which malignant (cancer) cells form in tubules of the kidney. - Smoking and misuse of certain pain medicines can affect the risk of renal cell cancer. - Signs of renal cell cancer include blood in the urine and a lump in the abdomen. - Tests that examine the abdomen and kidneys are used to detect (find) and diagnose renal cell cancer. - Certain factors affect prognosis (chance of recovery) and treatment options. 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 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).

Question: What are the stages of Renal Cell Cancer ?
Answer: Key Points - 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. - There are three ways that cancer spreads in the body. - Cancer may spread from where it began to other parts of the body. - The following stages are used for renal cell cancer: - Stage I - Stage II - Stage III - Stage IV 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, 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). - 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. 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 In stage I, the tumor is 7 centimeters or smaller and is found only in the kidney. Stage II In stage II, the tumor is larger than 7 centimeters and is found only in the kidney. Stage III In stage III: - the tumor is any size and cancer is found only in the kidney and in 1 or more nearby lymph nodes; or - cancer is found in the main blood vessels of the kidney or in the layer of fatty tissue around the kidney. Cancer may be found in 1 or more nearby lymph nodes. Stage IV In stage IV, cancer has spread: - beyond the layer of fatty tissue around the kidney and may be found in the adrenal gland above the kidney with cancer, or in nearby lymph nodes; or - to other organs, such as the lungs, liver, bones, or brain, and may have spread to lymph nodes.

Question: What are the treatments for Renal Cell Cancer ?
Answer: Key Points - There are different types of treatment for patients with renal cell cancer. - Five types of standard treatment are used: - Surgery - Radiation therapy - Chemotherapy - Biologic therapy - Targeted therapy - New types of treatment are being tested in clinical trials. - Patients may want to think about taking part in a clinical trial. - Patients can enter clinical trials before, during, or after starting their cancer treatment. - Follow-up tests may be needed. 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. Five types of standard 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. 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 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: - External radiation therapy uses a machine outside the body to send radiation toward the cancer. - Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. 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 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 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: - Nivolumab: Nivolumab is a monoclonal antibody that boosts the bodys immune response against renal cell cancer cells. - 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. See Drugs Approved for Kidney (Renal Cell) Cancer for more information. Targeted therapy 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. New types of treatment are being tested in clinical trials. Information about clinical trials is available from the NCI website. 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. 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. Follow-up tests may be needed. 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.
