FEC100
FEC100 Treatment
This document provides general information about your cancer treatment. It does not replace the advice of your health care professional. Always discuss your therapy with your health care team.
- This treatment consists of Fluorouracil, Epirubicin and Cyclophosphamide.
- Refer to the medication information sheet for each drug for more information.
- FEC100 is a drug combination for treating breast cancer.
- It is important to tell your oncologist about any other medical conditions you have, as some conditions may affect therapy with this treatment.
- Since these medications may harm your baby if used during pregnancy, women who have not yet reached menopause should use effective forms of birth control while being treated. Do not use birth control pills. Please discuss this with your oncologist.
- If you become pregnant, tell your oncologist right away.
- Do not breastfeed while undergoing treatment.
- Also, if you plan to have children, discuss this with your oncologist before starting your first treatment, as chemotherapy may affect your fertility and your chances of having a baby in the future.
- Your treatment plan consists of 6 chemotherapy cycles, given on one day, every 21 days. For each cycle, you will receive three drugs (Fluorouracil, Epirubicin and Cyclophosphamide) through a vein in your arm (IV) on day 1.
- You will have a blood test before each treatment to check if your blood counts are high enough for you to receive chemotherapy.
- Epirubicin can cause damage to surrounding tissues if it leaks out of the vein and into the surrounding area. The nurses are extremely careful when giving this medication, but tell them immediately if you experience burning or pain with the injection.
- Epirubicin, rarely, can have an effect on the function of the heart, which in some patients might cause shortness of breath, fatigue and leg swelling. Your oncologist may order special heart tests, usually before you have your first treatment. Tell your oncologist if you are concerned about any symptoms or if you have had any heart problems.
- Cyclophosphamide can irritate your bladder. Starting the day before treatment, for a total of 2-3 days, drink plenty of fluids (at least 8 glasses per day) during the day and empty your bladder (pass urine) frequently. Tell your oncologist or nurse if you experience pain on urination, see blood in your urine, or need to urinate small amounts frequently.
- Fluorouracil will make your skin more sensitive to sunlight. Limit the amount of sunlight to which you are exposed. Apply sunscreen with UVA and UVB protection and a SPF of at least 30. Use a lip balm with sunscreen for your lips. Wear long sleeved shirts, long pants and hats.
- All patients will experience some or total hair loss. This generally starts 2 to 3 weeks after the first injection. Your scalp may feel tender. It’s a good idea to consider a wig or other head covering before starting treatment. Hair loss on your face (e.g. eyebrows, eyelashes) and body can also occur. Your hair will start to grow back once your treatment is over. The colour and texture of your new hair may be different.
- Medications in this regimen may make your periods heavier or lighter. Your periods may even stop completely. This may be permanent. You may develop symptoms of menopause such as hot flashes, vaginal dryness, mood swings and changes in sexual desire. Please discuss any concerns with your nurse or oncologist.
- Tell your oncologist, nurse, and pharmacist about any other prescription and non-prescription medications you are currently taking. Check with your oncologist, nurse or pharmacist before you start taking any new drugs, including herbal or alternative treatments. Also, tell other healthcare professionals you are seeing about the chemotherapy you are receiving.
- Due to increased risk of developing infections, check with your oncologist before having any vaccinations. Also check with your oncologist, before any surgery or dental work.
- If you are taking ASA (Aspirin®, acetylsalicylic acid), please discuss this with your oncologist as this may interfere with your chemotherapy treatment. For headache, fever, or occasional aches and pains, use acetaminophen (Tylenol®) instead of ASA.
The table below lists some common or important side effects with this treatment. You may not have all of the side effects. Other side effects may occur. If you have any unusual or bothersome symptoms, discuss with your doctor.
