Treatment Name: Sorafenib (Nexavar®)

Sorafenib (Nexavar®) is a Chemotherapy Regimen for Renal Cell Carcinoma - Kidney Cancer

How does sorafenib work?
Sorafenib is designed to slow the growth of cancer cells by inhibiting proteins inside the cell uses to grow and survive. Sorafenib is in a class of medications called Tyrosine Kinase Inhibitors, often referred to as "TKIs."

Goals of therapy:
Sorafenib is taken to shrink kidney tumors and decrease symptoms of renal cell carcinoma (RCC). Sorafenib is not commonly given with the goal of cure.

How often is monitoring needed?
Labs (blood tests) may be checked before treatment and periodically during treatment, most commonly before a new cycle is started. Labs often include: Complete Blood Count (CBC), Comprehensive Metabolic Panel (CMP), urinalysis, and thyroid stimulating hormone (TSH).

How often is imaging needed?

Imaging may be checked before treatment and every 8 weeks until the end of treatment. Imaging may include: computerized tomography (CT) scans and magnetic resonance imaging (MRI)

How might blood test results/imaging affect treatment?
Depending upon the results, your doctor may advise to continue sorafenib as planned, or delay or switch therapy

ChemoExperts Tips

  • Sorafenib can possibly impair your body’s ability to heal wounds. Talk to your oncologist about any planned surgeries and let your surgeon know that you are taking sorafenib
  • A pharmacist should ALWAYS review your medication list to ensure that drug interactions are prevented or managed appropriately
  • You can tell if a medication is a TKI if the name ends in "nib," such as sorafenib. TKIs are usually oral medications taken by mouth
  • Clinical trials may exist for renal cell carcinoma. Ask your doctor if any studies are currently enrolling in your area. If not, go to to search for other centers offering study medications

Emotional Wellness

What is Emotional Wellness?
Emotional wellness is having a positive outlook balanced with a realistic understanding of current life events. This requires both an awareness and acceptance of your emotions. It is with this knowledge that you can develop a plan to take the necessary actions to positively impact your life.

Emotional wellness uses an ongoing process to continually reflect on the stressors of life in a constructive manner to move forward and create happiness.

Because emotional wellness is deeply connected with physical, social, and spiritual wellness, pursuing it often becomes particularly difficult in times of major illness. Despite this difficulty, working toward emotional wellness has been connected to improved treatment outcomes and a higher likelihood of achieving goals of therapy.

  • May interact with certain antifungal and seizure medications. Ask your doctor or pharmacist to review your medications for any possible interactions
  • May interact with grapefruit and grapefruit juice, causing increased blood levels of sorafenib. This could increase your risk of experiencing side effects. Avoid eating grapefruit and drinking anything containing grapefruit juice during treatment
  • Avoid therapy with St. Johns Wort as it will decrease blood levels of sorafenib. This could decrease the effectiveness of sorafenib
General Sorafenib (Nexavar) Side Effects
  • May increase your risk of heart attack. Get help immediately if you experience symptoms such as chest pain, shortness of breath, lightheadedness, nausea, vomiting, and sweating

What is Renal Cell Carcinoma - Kidney Cancer?

A malignant disease of the cells found in the kidney. Renal cell carcinoma (RCC) is a rare condition and is the most commonly diagnosed type of kidney cancer. Known causes of RCC include smoking, obesity, hypertension, family history of RCC, and a genetic disease known as Von Hippel-Lindau disease. The stage of RCC can vary at diagnosis and throughout treatment. RCC uses the TNM (Tumor, Node, Metastasis) staging system and is grouped into stages I, II, III, and IV. The effectiveness of the treatment may depend upon the stage at diagnosis.

NOTE: Treatment Options listed below are not all-inclusive. Other treatments may be available. ChemoExperts provides drug information and does not recommend any one treatment over another. Only your Doctor can choose which therapy is appropriate for you.

What is a CBC?

A Complete Blood Count (CBC) is a frequently ordered blood test that tells clinicians the status of your: 1) White blood cell count, 2) Hemoglobin, and 3) Platelet count at the time the test was taken.

Common uses:
1) White blood cell count (WBC): is used to determine infection risk, or response to chemotherapy. Certain chemotherapy agents may harm our good infection-fighting cells. Sometimes chemotherapy may need to be delayed to allow these cells to recover.

2) Hemoglobin: is used to determine if someone is anemic. Anytime the hemoglobin is below 12 g/dL, the person is said to be anemic. Red blood cell transfusions, and sometimes iron can be given to restore the hemoglobin level, but anemia treatment should always aim at treating the underlying cause or condition.

3) Platelet count: is used to determine if the risk of bleeding is increased or if a platelet transfusion is required to prevent bleeding. Certain medications that increase bleeding risk, such as: aspirin, certain chemotherapy agents, and blood thinners, may need to be stopped temporarily until the platelet count is within a safe range.

What is a CMP?

A Comprehensive Metabolic Panel (CMP) is a frequently ordered blood test that tells clinicians the status of your: 1) Electrolytes & Acid/Base status2) Kidney function, 3) Liver function, 4) Blood sugar, and 5) Calcium at the time the test was taken. It is commonly used to monitor liver and kidney function when beginning new medications such as chemotherapy. A total of 14 tests are run simultaneously and are shown below.

Electrolytes & Acid/Base status:
1) Sodium, 2) Potassium, 3) Carbon dioxide, 4) Chloride

Kidney Function:
5) BUN (blood urea nitrogen), 6) Serum creatinine (Scr)

Liver Function:
7) AST, 8) ALT, 9) Total bilirubin, 10) Alk Phos, 11) Albumin, 12) Total protein

Blood sugar:
13) Serum glucose

14) Serum calcium

What does Cure mean?

The word “cure” means there are no cancer cells left in the body and cancer will never come back. Depending on the cancer type and stage, this may be the true goal of therapy. However, it is very difficult to prove all cancer cells are gone. Even though images, like X-rays and MRI’s, and blood tests may not show any signs of cancer, there can be a small amount of cancer cells still left in the body. Because of this, the word “remission” is used more often. This means there are no signs or symptoms of cancer. Patients in remission are followed closely for any signs of cancer returning. Sometimes, more chemotherapy may be given while in remission to prevent the cancer from coming back.

Doctors usually do not consider a patient “cured” until the chance of cancer returning is extremely low. If cancer does return, it usually happens within 5 years of having a remission. Because of this, doctors do not consider a patient cured unless the cancer has not come back within 5 years of remission. The five-year cutoff does not apply to all cancers.
