Treatments and drugs
By Mayo Clinic staffTogether, you and your treatment team will discuss your kidney cancer treatment options. The best approach for you may depend on a number of factors, including your general health, the kind of kidney cancer you have, whether the cancer has spread and your preferences for treatment.
Surgery
Surgery is the initial treatment for the majority of kidney cancers. Surgical procedures used to treat kidney cancer include:
- Removing the affected kidney (nephrectomy). Radical nephrectomy involves the removal of the kidney, a border of healthy tissue and the adjacent lymph nodes. The adrenal gland also may be removed. Nephrectomy can be an open operation, meaning the surgeon makes one large incision to access your kidney. Or nephrectomy can be done laparoscopically, using several small incisions to insert a video camera and tiny surgical tools. The surgeon watches a video monitor to perform the nephrectomy.
- Removing the tumor from the kidney (nephron-sparing surgery). During this procedure, also called partial nephrectomy, the surgeon removes the tumor and a small margin of healthy tissue that surrounds it, rather than removing the entire kidney. Nephron-sparing surgery can be an open procedure, or it may be performed laparoscopically. Nephron-sparing surgery may be an option if you have a small kidney cancer or if you only have one kidney. When nephron-sparing surgery is possible, it's generally preferred over radical nephrectomy since retaining as much kidney tissue as possible may reduce your risk of later complications, such as kidney disease and the need for dialysis.
The type of surgery your doctor recommends will be based on your cancer and its stage, as well as your health. Surgery carries a risk of bleeding and infection.
Treatments when surgery isn't possible
For some people, surgery isn't an option. In these situations, kidney cancer treatments may include:
- Treatment to freeze cancer cells (cryoablation). During cryoablation, a special needle is inserted through your skin and into your kidney tumor using X-ray guidance. Gas in the needle is used to cool down or freeze the cancer cells. There are few long-term data about the safety and efficacy of cryoablation. It's typically reserved for people who can't undergo other surgical procedures and those who have small kidney tumors.
- Treatment to heat cancer cells (radiofrequency ablation). During radiofrequency ablation, a special needle is inserted through your skin and into your kidney tumor using X-ray guidance. An electrical current is run through the needle and into the cancer cells, causing the cells to heat up or burn. There are few long-term data about the safety and efficacy of radiofrequency ablation. Radiofrequency ablation may be an option for people who can't undergo other surgical procedures and those with small kidney tumors.
Treatments for advanced and recurrent kidney cancer
Kidney cancer that recurs and kidney cancer that spreads to other parts of the body may not be curable, but may be controlled with treatment. In these situations, treatments may include:
- Surgery to remove as much of the kidney tumor as possible. Even when surgery can't remove all of your cancer, in some cases it may be helpful to remove as much of the cancer as possible. Surgery may also be used to remove cancer that spreads to other areas of the body.
- Drugs that use your immune system to fight cancer (biological therapy). Biological therapy (immunotherapy) uses your body's immune system to fight cancer. Drugs in this category include interferon and aldesleukin (Proleukin), which are synthetic versions of chemicals made in your body. Side effects of these drugs include chills, fever, nausea, vomiting and loss of appetite.
- Treatment that targets specific aspects of your cancer (targeted therapy). Targeted treatments block specific abnormal signals present in kidney cancer cells that allow them to proliferate. These drugs have shown promise in treating kidney cancer that has spread to other areas of the body. The targeted drugs axitinib (Inlyta), bevacizumab (Avastin), pazopanib (Votrient), sorafenib (Nexavar) and sunitinib (Sutent) block signals that play a role in the growth of blood vessels that provide nutrients to cancer cells and allow cancer cells to spread. Temsirolimus (Torisel) and everolimus (Afinitor) are targeted drugs that block a signal that allows cancer cells to grow and survive. Targeted therapy drugs can cause side effects, such as a rash that can be severe, diarrhea and fatigue.
- Radiation therapy. Radiation therapy uses high-powered energy beams, such as X-rays, to kill cancer cells. Radiation therapy is sometimes used to control or reduce symptoms of kidney cancer that has spread to other areas of the body, such as the bones.
- Clinical trials. Clinical trials are studies of new treatments and new techniques for treating kidney cancer and other diseases. Participating in a clinical trial may give you a chance to try the latest treatments, but it can't guarantee a cure. Discuss the available clinical trials with your doctor and carefully weigh the benefits and risks. Some kidney cancer clinical trials are studying new and existing targeted therapies to determine the best ways to use this new class of drugs.
