Treatment Name: FOLFOX + Bevacizumab

FOLFOX + Bevacizumab is a Chemotherapy Regimen for Colon Cancer

How does FOLFOX + Bevacizumab work?
Each chemotherapy drug in this treatment is designed to kill cancer cells. Bevacizumab stops the growth of blood vessels that supply nutrition to the tumors.

FOL - folinic acid (leucovorin)
F - fluorouracil (5-FU)
OX - oxaliplatin (Eloxatin®)

Goals of therapy: 
FOLFOX + bevacizumab can be given to shrink tumors early in treatment of a colon cancer patient with a goal of then removing the cancer by surgery. If the stage and grade of cancer are favorable, such as early stage colorectal cancer, the goal is to cure. If it is advanced colorectal cancer, or metastatic, then chemotherapy can still decrease disease symptoms and extend life.

  • Folinic acid (Leucovorin) intravenous infusion (I.V.), given over two hours before fluorouracil on Day 1
  • Oxaliplatin I.V. given over two hours on Day 1
  • Fluorouracil (5-FU) I.V. push, usually given over 3 to 5 minutes on Day 1
  • Fluorouracil (5-FU) continuous I.V. infusion (via home-infusion pump) over 46 hours beginning Day 1 and ending on Day 2
  • Bevacizumab I.V. given over 30 to 90 minutes on Day 1

Typically, all medications are started on the same day. 

FOLFOX + Bevacizumab  is usually given in an outpatient health care infusion center, allowing the cancer patient to go home afterwards. Often, this treatment can take upwards of four to five hours.

Each two-day FOLFOX treatment is repeated every 14 days. This is known as one Cycle. Each cycle may be repeated indefinitely. Duration of therapy may last many months, or years, depending upon response, tolerability, and number of cycles prescribed.

How often is monitoring needed? 
Labs (blood tests) are usually checked before each treatment.  Labs often include: Complete Blood Count (CBC), Comprehensive Metabolic Panel (CMP), blood pressure, and urine protein level. CEA (carcinoembryonic antigen) may be checked every six weeks to monitor tumor response.

How often is imaging needed? 
Imaging, such as computerized tomography (CT) scan and/or magnetic resonance imaging (MRI), is checked before treatment.  These are repeated after every few cycles or about every six weeks.

How might blood test results/imaging affect treatment? 
Depending upon the results, your doctor may advise to continue FOLFOX + Bevacizumab as planned, reduce the dose of future treatments, delay the next dose until the side effect goes away, or switch to an alternative therapy. The dose of oxaliplatin may be reduced if persistent (lasting more than 14 days) tingling, pain, numbness, or burning are experienced. Fluorouracil or oxaliplatin doses may be reduced for avoiding infection if the white blood cells, known as neutrophils, drop too low. Doses may also be lowered if the platelet count drops too low, or for severe side effects such as severe mouth sores or diarrhea. Other dose reductions may be recommended by your doctor.

ChemoExperts Tips

  • Patients will have an infusion pump strapped to their body for 2 days to allow fluorouracil (5-FU) to continuously infuse into a vein. The I.V. line is connected at the end of the chemotherapy session by a nurse. When the infusion is finished the patient will have to go back to the infusion center or hospital to have it disconnected unless a home health nurse comes to the patient’s home to do this
  • A pharmacist should ALWAYS review your medication list to ensure that drug interactions are prevented or managed appropriately

  • Clinical trials may exist for colon cancer. Ask your doctor if any studies or cancer research 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.

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.

What is an I.V. push?

An intravenous medication that is usually prepared in a syringe and infused by vein over a short period of time, such as 15 minutes or less

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, doctors use 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 Leucovorin?

Leucovorin is not a chemotherapy agent. It is a special form of folic acid (vitamin B9) that helps increase the effectiveness of fluorouracil. Folic acid should NOT be confused with leucovorin (foliNic acid) as it does not work the same way.
