Treatments for renal cell carcinoma can cause side effects that range from mild to potentially life threatening. Possible treatments include chemotherapy, kidney surgery, and immunotherapy.

Renal cell carcinoma (RCC) is the most common type of cancer affecting the kidneys. It accounts for about 90% of all kidney cancer cases.

All treatments for RCC may cause side effects. This article discusses some of the potential side effects of the following RCC treatments:

  • kidney surgery
  • radiation therapy
  • immunotherapy
  • targeted therapy
  • chemotherapy

For RCC stages 1 to 3, experts recommend partial or radical (total) nephrectomy.

A partial nephrectomy removes the part of the kidney that contains the suspected cancerous tumor. A radical nephrectomy removes the entire kidney.

Surgeons typically use keyhole surgery, or laparoscopy, to perform a nephrectomy.

Laparoscopic surgery and open surgery have similar complication rates, but recovery from laparoscopic surgery is often easier. Robot-assisted surgery may reduce complications and also offers more comfortable post-operative recovery.

Partial nephrectomy

According to a 2022 review, 20% of people who have a partial nephrectomy experience complications. The most serious include excessive bleeding and urinary fistulas—abnormal openings between the urinary tract and another organ that cause urine leakage.

Radical nephrectomy

An open radical nephrectomy is a more invasive procedure than laparoscopic radical nephrectomy. In 5% to 10% of radical nephrectomies, a person will sustain damage to a nearby organ or pedicle, which is tissue that connects body parts.

Overall risks

Both types of nephrectomy carry some risks, including:

Radiation is a common treatment for several different cancers, including RCC. It uses high energy rays or particles to destroy cancer cells. It may be a good choice for people who have only one kidney or are not able to have surgery for health reasons.

Some common side effects of radiation therapy include:

Healthcare professionals may use immunotherapy in later stages of RCC. Immunotherapy helps a person’s immune system target and attack cancer cells, shrinking or destroying tumors.

There are several types of immunotherapy. If a person experiences side effects, their doctor may recommend another immunotherapy type.

Side effects vary depending on the type of immunotherapy a person receives. However, side effects may include:

A doctor may recommend targeted therapy for stage 4 RCC treatment. Targeted therapy uses large-molecule or small-molecule drugs to destroy specific substances within cancer cells or weaken enzymes and proteins on the outside of these cells.

As with all kidney cancer treatments, targeted therapy may cause some side effects. Not everyone experiences side effects, and the severity of any side effects can vary.

Some potential side effects include:

Chemotherapy uses medications to kill or destroy cancer cells. People may take these medications orally or receive them as an intravenous infusion.

It is not a standard treatment for RCC because the cancer cells do not typically respond well to it.

Chemotherapy side effects vary depending on the medication, dosage, and length of treatment, but they may include:

People with RCC should speak with a healthcare professional about their treatment options and any potential side effects they may experience.

If a person is concerned about any of the side effects they are experiencing, they should speak with their doctor, who may be able to recommend an alternative treatment or ways to manage the side effects.

RCC treatments can be safe and effective. However, they may also cause side effects that range from mild to potentially life threatening in severity.

Some people may not experience any side effects from RCC treatment. However, a person should speak with a doctor if they experience unpleasant or potentially serious side effects. In some cases, they may be able to switch treatments.
