Metastatic renal cell carcinoma is cancer in your kidneys that has spread to other parts of your body. It's also called stage IV renal cell cancer.

Cancer is harder to treat after it spreads, but it’s not impossible. You and your doctor still have many options.

Treatments for metastatic renal cell cancer include:

  • Surgery
  • Immunotherapy
  • Targeted therapy
  • Radiation therapy
  • Chemotherapy

Talk about all your options with your doctor. Find out how each treatment can help you and what side effects it can have, so you can choose the best one for you.

Surgery

Surgery is the main treatment for cancer that hasn’t grown outside of the kidneys. Yet it can still be an option if your cancer has spread.

Radical nephrectomy is the main operation for this type of cancer. During this procedure, your surgeon removes the:

  • Kidney that has the tumor
  • Adrenal gland, which sits on top of that kidney
  • Lymph nodes nearby
  • Fat around the organ

If the cancer hasn't spread far, surgery may be a cure. If it has gone to other parts of your body, you'll also need other treatments like targeted therapy and immunotherapy. These treatments kill any cancer cells throughout your body that are left behind after surgery.

Immunotherapy

Immunotherapy uses substances made in a lab or by your body to help your immune system fight kidney cancer. It’s also called biologic therapy. There are a few types:

Interleukin-2 (IL-2) is a man-made version of proteins that your immune system makes called cytokines, which help destroy tumor cells. The medicine activates your immune system to attack the cancer.

You can take IL-2 in one of two ways:

  • Through a thin tube that goes into a vein (IV). You get it in a hospital.
  • As a shot under your skin. You can get this in a doctor's office or give it to yourself at home.

In large doses, IL-2 can shrink tumors. But it only helps a small group of people with advanced renal cell cancer. And it can cause side effects like:

  • Low blood pressure
  • Fluid in the lungs
  • Kidney damage
  • Heart attack
  • Fatigue
  • Bleeding
  • Chills
  • Fever

Interferon alpha slows a tumor’s growth. You get it as a shot under your skin. It doesn't work very well by itself. Usually you'll take it with another drug, like bevacizumab (Avastin).

Side effects of this treatment include:

  • Flu-like symptoms, such as fever and chills
  • Nausea
  • Fatigue

Checkpoint inhibitors. Your immune system uses a system of "checkpoints" on the surface of your cells to tell which ones are normal and which are harmful. Cancer cells can sometimes use checkpoints to pass as healthy cells and hide from your immune system.

Checkpoint inhibitors are a new type of drug that turn off checkpoints to help the immune system find cancer cells.

Nivolumab (Opdivo) is one of these medicines that can treat metastatic renal cell cancer. You get it through a vein (IV) every 2 weeks. It can shrink tumors or slow their growth.

Side effects of Opdivo include:

  • Red patches or a rash on your skin
  • Feeling tired
  • Diarrhea
  • Belly pain
  • Trouble breathing, cough, or chest pain
  • Nausea
  • Sore or dry mouth
  • Headache

 

Targeted Therapy

These medicines target parts of cancer cells that help them grow and survive. They’re designed to kill cancer without harming healthy cells.

Targeted therapies for renal cell cancer include:

Anti-angiogenesis therapy. Tumors need a blood supply to grow. Angiogenesis is the process that tumors use to make new blood vessels. Anti-angiogenesis therapy cuts off blood vessel growth to "starve" tumors.

One of these drugs, bevacizumab (Avastin), blocks a protein called VEGF, which helps tumors grow new blood vessels. You often take it with the immunotherapy drug interferon alpha.

You get Avastin as an IV through a vein once every 2 weeks. Each IV takes between 30 and 90 minutes.

Side effects include:

  • Fainting
  • Not feeling hungry
  • Change in the way food tastes
  • Heartburn
  • Diarrhea
  • Weight loss
  • Mouth sores

Tyrosine kinase inhibitors (TKIs) target proteins called tyrosine kinases that help cancer cells and their blood vessels grow. These drugs include:

  • Cabozantinib (Cabometyx)
  • Pazopanib (Votrient)
  • Sorafenib (Nexavar)
  • Sunitinib (Sutent)
  • Axitinib (Inlyta)
  • Lenvatinib (Lenvima)

You take TKIs as a pill once or twice a day. Side effects from these drugs include:

  • Nausea
  • Diarrhea
  • High blood pressure
  • Pain in the hands and feet
  • Liver problems

mTOR inhibitors are medicines that target the mTOR protein, which helps cancer cells grow. They include:

  • Everolimus (Afinitor)
  • Temsirolimus (Torisel)

Afinitor is a pill you take once a day. Torisel comes in an IV you get once a week.

Side effects from mTOR inhibitors include:

  • Mouth sores
  • Rash
  • Weakness
  • Not feeling hungry
  • Fluid buildup in the face or legs
  • High blood sugar and cholesterol

 

Radiation Therapy

This treatment uses high-energy X-rays to kill cancer cells. Radiation doesn't work very well on kidney cancer. But it might be an option if you can't have surgery. It can also relieve symptoms like pain or swelling. Treatments that help you feel better without killing the cancer are called palliative therapies.

Usually, you'll get radiation from a machine outside your body. This is called external-beam radiation.

Side effects of radiation treatment include:

  • Fatigue
  • Skin redness
  • Upset stomach
  • Diarrhea

 

Chemotherapy

Chemotherapy uses medicine to kill cancer cells all over your body. It can treat cancers that have spread.

This treatment usually doesn’t work very well for renal cell cancer. But it might be an option if you've already tried immunotherapy, targeted drugs, or both. Some chemotherapy drugs, including vinblastine, capecitabine, and gemcitabine, help a small number of people with advanced kidney cancer.

You take chemotherapy as a pill, or you get it through an IV into a vein. You usually get it in cycles -- a few weeks on, followed by a break.

Side effects of chemotherapy include:

  • Hair loss
  • Mouth sores
  • Not feeling hungry
  • Feeling tired
  • Nausea and vomiting
  • Diarrhea or constipation
  • A higher chance of infections

 

Finding the Right Treatment

Your doctor will help you decide on the best treatment or combination of treatments for your cancer. If you try a few and they don't work, ask your doctor about joining a clinical trial. These trials test new therapies for kidney cancer to see if they are safe and if they work. Your doctor can tell you if one of these trials might be a good fit for you.
