Regorafenib (Stivarga®) is a Chemotherapy Regimen for Colon Cancer

How does regorafenib work?
Regorafenib is a chemotherapy drug that is a small molecule called a Tyrosine Kinase Inhibitor (TKI) that turns off several proteins that are not functioning properly which help cancer cells to grow and survive.

Goals of therapy:
Regorafenib is taken to shrink tumors and decrease symptoms of colon cancer and is not commonly given with the goal of cure.

How often is monitoring needed?
Labs (blood tests) may be checked before treatment, every two weeks for the first two months of treatment, then monthly thereafter. Labs often include: Complete Blood Count (CBC), Comprehensive Metabolic Panel (CMP), plus any others your doctor may order. Blood pressure is typically checked weekly for the first six weeks of treatment, and then monthly thereafter. CEA (carcinoembryonic antigen), a tumor marker, may be checked periodically.

How often is imaging needed?
Imaging may be checked before treatment then approximately every 8 weeks. Imaging may also be checked if you have any signs or symptoms of a serious side effect. Imaging may include: X-rays, magnetic resonance imaging (MRI), computerized tomography (CT) scans, or positron emission tomography (PET) scans.

How might blood test results/imaging affect treatment?
Depending upon the results, your doctor may advise to continue regorafenib as planned, reduce the dose of future treatments, delay the next dose until the side effect goes away, or switch to an alternative therapy.

ChemoExperts Tips

  • Contact your doctor immediately if you experience severe abdominal pain or yellowing of the skin or eyes as these may be signs of severe liver injury
  • If you have high blood pressure that is not well controlled, you may need to take additional medications or have your current medications adjusted before starting regorafenib
  • Go to the nearest emergency room if you experience chest pain, shortness of breath, or feel dizzy and lightheaded as these may be signs of a serious heart problem
  • Let your doctor know when you are going to have any surgeries or procedures as regorafenib may need to be stopped for at least two weeks prior to the surgery or procedure
  • A pharmacist should ALWAYS review your medication list to ensure that drug interactions are prevented or managed appropriately

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.

What is Colon Cancer?

A disease of the cells from the large intestine.  Colon cancer is the third most common cancer among both men and women.  Known causes include:  family history, poor diet, sedentary lifestyle, obestity, diabetes, history of colon polyps, smoking, heavy alcohol use, prior radiation treatment to abdomen for other cancers, and old age.  The stage can vary at diagnosis and throughout treatment.  Stages of colon cancer use Tumor, Node, Metastasis (TNM) staging as well as Stage Grouping using Stages 0, I, II, III, or IV.  More specific subytpes of the primary stages exist, for example Stage II may be further divided into stages IIa, IIb, or IIc, and stage subtype may effect treatment options. 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.

  • Usual starting dose: 160 mg (four 40 mg tablets) by mouth once daily for 21 consecutive days followed by 7 days off

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.

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 is Specialty Pharmacy?

A pharmacy that manages the handling and services for drugs used by patients with rare or chronic diseases. This has expanded in the last several years to include very expensive drugs used to treat cancer, mainly oral cancer medications or injections that can be taken at home.
