A Complete Guide to Medications for Treating Kidney Cancer
Explore how modern medicines—from immunotherapies to targeted drugs—are shaping kidney cancer treatment and outcomes today.
Kidney cancer, while traditionally managed with surgery in early stages, increasingly relies on medications for advanced or recurrent cases. This guide discusses the latest advances in kidney cancer medications, including immunotherapy, targeted therapies, treatments for specific cancer types, use in children, expected effectiveness, possible side effects, and practical considerations for patients and caregivers.
Overview
Medications have become a cornerstone of kidney cancer treatment, especially for advanced forms. In the early stages, surgical removal of tumors (nephrectomy) or minimally invasive techniques like thermal ablation are standard. However, in cases where the cancer is metastatic—meaning it has spread beyond the kidney—or poses a high risk of recurrence, medication-based therapies are crucial for improving outcomes and survival rates.
The specific approach your healthcare provider recommends depends on:
- Cancer type—most commonly renal cell carcinoma (RCC), but also Wilms tumors and transitional cell (urothelial) carcinoma
- The stage of the cancer
- The patient’s overall health
- Other concurrent treatments
- Health insurance coverage and access to therapies
Unlike some other cancers, standard chemotherapy is rarely effective against most kidney cancers. Instead, immunotherapies and targeted therapies are the most widely used treatments.
What Medication is Used to Treat Kidney Cancer?
The first-line medications for kidney cancer include targeted therapy drugs and immunotherapy. The exact medication a doctor prescribes will generally follow evidence-based practice guidelines, such as those from the National Comprehensive Cancer Network (NCCN), which prioritize medications based on type and stage of cancer.
- Immunotherapy: Boosts or modifies the immune system to help it attack cancer cells more effectively.
- Targeted Therapy: Focuses on specific molecules and pathways crucial to cancer cell survival and replication, usually with fewer side effects than traditional chemotherapy.
- Chemotherapy: Occasionally used for certain rare kidney cancers such as Wilms tumor or transitional cell carcinoma but less effective for the most common type—RCC.
Doctors now frequently combine immunotherapy and targeted therapy, which can shrink disease, slow tumor growth, and reduce the risk of recurrence.
Immunotherapy for Kidney Cancer
Immunotherapy harnesses the power of the immune system, aiming to help it find and destroy cancer cells more efficiently. For kidney cancer, the most prominent drugs are immune checkpoint inhibitors, which block proteins that prevent immune cells (T cells) from attacking tumors. By inhibiting these proteins, checkpoint inhibitors make cancer cells more vulnerable to immune destruction.

Common Immunotherapy Drugs for Kidney Cancer
- Nivolumab (Opdivo): Often combined with other drugs for enhanced effect.
- Ipilimumab (Yervoy): A standard partner for nivolumab in initial therapy for advanced kidney cancer.
- Avelumab (Bavencio): Used in certain treatment protocols.
- Pembrolizumab (Keytruda): Part of several treatment combinations.
Earlier immunotherapies for kidney cancer included:
- Interleukin-2 (IL-2): Once a mainstay for advanced kidney cancer, now used less frequently due to significant side effects and the need for good overall organ function in patients.
- Interferon alpha: Sometimes still used, often in combination with targeted therapies (like bevacizumab). Administered as an injection under the skin.
Most immunotherapy drugs are given by intravenous (IV) infusion, usually at an oncology clinic or hospital.
Targeted Therapy for Kidney Cancer
Targeted therapies are designed to focus on specific genetic or molecular features of cancer cells. They usually suppress the growth signals in tumor cells or prevent the formation of blood vessels the tumor needs to grow (angiogenesis). Unlike chemotherapy, these drugs minimize harm to healthy cells and therefore often cause milder side effects.
Key Targeted Therapies for Kidney Cancer
- Tyrosine Kinase Inhibitors (TKIs):
- Sunitinib (Sutent)
- Pazopanib (Votrient)
- Tivozanib (Fotivda)
- Cabozantinib (Cabometyx)
- Axitinib (Inlyta)
- Lenvatinib (Lenvima)
- Other targeted medications:
- Bevacizumab (Avastin): Targets VEGF (a key signal for blood vessel growth).
- Everolimus (Afinitor): Blocks mTOR, involved in cancer cell growth.
- Belzutifan (Welireg): Inhibits HIF-2α, relevant to certain hereditary RCC (such as due to Von Hippel-Lindau disease).
Note: Most targeted therapy drugs for kidney cancer are taken orally as a pill once or twice daily.
Chemotherapy for Kidney Cancer
Chemotherapy uses cytotoxic drugs to kill rapidly dividing cells. However, conventional chemotherapy is generally ineffective against clear cell renal cell carcinoma (RCC), the most prevalent form of kidney cancer. It may be considered for:
- Wilms tumor (a childhood kidney cancer subtype)
- Transitional cell (urothelial) carcinoma of the kidney or ureter
- Situations where other therapies have failed
Chemotherapy can be given as an IV infusion or as oral pills. Typical agents include:
- Cisplatin
- 5-fluorouracil (5-FU)
- Gemcitabine
Chemotherapy is more commonly integrated into the treatment of pediatric and rare kidney cancers.
Medications for Upper Tract Urothelial Carcinoma (UTUC)
Upper tract urothelial carcinoma (UTUC) is a rare form of kidney cancer that starts in the lining of the renal pelvis or ureter. Standard treatments largely parallel those for bladder cancer and often include:
- Chemotherapy: Platinum-based agents like cisplatin are commonly used.
- Immunotherapy: Checkpoint inhibitors may be available for advanced or refractory cases.
Treatments for Children with Kidney Cancer
Wilms tumor represents the majority of kidney cancers in children. Treatment protocols are adjusted accordingly:
- Surgical resection: Still the primary treatment.
- Chemotherapy: Medications such as vincristine and actinomycin D find regular use alongside surgery.
- Radiation therapy: Utilized for higher-risk or more advanced cases.
The vast majority of children with Wilms tumor now achieve long-term remission due to these optimized protocols.
Effectiveness of Kidney Cancer Medications
The effectiveness of treatments is measured in terms of tumor response (shrinkage), disease-free survival, and overall survival rates.
| Treatment Type | Common Effectiveness | Key Consideration |
|---|---|---|
| Immunotherapy | Improves survival in advanced/metastatic RCC, can produce long-term responses | May not benefit all patients, best in combination with other drugs |
| Targeted Therapy | Effectively slows progression, reduces recurrence risk | Tumor resistance may develop over time |
| Chemotherapy | Limited effectiveness in RCC, high efficacy in Wilms tumor | Reserved for specific subtypes or salvage therapy |
Survival rates continue to improve as newer generations of immunotherapy and targeted drugs become available.
Side Effects of Kidney Cancer Medications
Like all potent treatments, the medications used for kidney cancer carry the possibility of side effects. These vary by drug class:
- Immunotherapy side effects:
- Fatigue
- Skin rash or irritation
- Flu-like symptoms
- Risk of autoimmune reactions (can affect lungs, liver, thyroid, or intestines)
- Targeted therapy side effects:
- High blood pressure
- Diarrhea
- Hand-foot syndrome (redness/swelling of palms and soles)
- Anemia and low blood counts
- Changes in taste or appetite
- Chemotherapy side effects:
- Nausea and vomiting
- Hair loss
- Increased infection risk (due to low white blood cells)
- Mouth sores
- Fatigue
Most side effects can be managed with supportive care, treatment pauses, or dose adjustments. It’s essential to promptly report any side effects to your healthcare team.
What to Expect When Taking Medication for Kidney Cancer
Successful medication management for kidney cancer requires ongoing communication with your care team. Here’s what patients can typically expect:
- Many therapies are delivered via IV at infusion centers, especially immunotherapy drugs.
- Targeted therapies are often oral, with daily schedules and regular blood tests to monitor organ function.
- Your care team will screen for and manage side effects aggressively.
- Most patients combine medication with other therapies (such as surgery or radiation), particularly if cancer is advanced or recurrent.
- Treatment will be adjusted over time, based on how your cancer responds and how well you tolerate each medicine.
Many new treatments are emerging rapidly, and your doctor may offer access to clinical trials for innovative medication combinations or next-generation therapies.
Frequently Asked Questions (FAQs)
What is the first-line medication for kidney cancer?
Immunotherapy and targeted therapies, often in combination, are first-line for most patients with advanced renal cell carcinoma. Options include nivolumab plus ipilimumab or targeted TKIs like sunitinib, depending on cancer features and patient health.
Is chemotherapy ever used for kidney cancer?
Chemotherapy is rarely effective for clear cell RCC but may play a role in rare types such as Wilms tumor or transitional cell carcinoma. It’s usually reserved for special circumstances or clinical trials.
Will I need medication after surgery for kidney cancer?
If your cancer is high-risk, recurrent, or metastatic, your doctor may recommend medications (immunotherapy or targeted therapy) after or instead of surgery. Early-stage cancers treated with surgery alone often do not require medications.
What factors determine which medication I receive?
Your cancer type, stage, molecular features, previous treatments, overall health, side effect profile, and even insurance coverage can all influence the choice of medication.
Can children with kidney cancer take the same medicines as adults?
Pediatric kidney cancers, such as Wilms tumor, are treated with protocols specifically optimized for children. While some medications overlap, dosages, and combinations differ, and response rates are much higher for children.
