What is this treatment?

CYCLDOCE is the code name of your breast cancer treatment regimen.

A regimen is a combination of medications to treat cancer.

This regimen name is made up of one or more letters from the names of the 2 medications in your treatment.

Here are the names of the medications in this regimen:

CYCL = CYCLophosphamide

DOCE = DOCEtaxel (also called Taxotere®)

For most people, treatment lasts 12 weeks. The treatment is divided into 4 cycles. Each cycle is 3 weeks long.

Here is a picture of the schedule for CYCLDOCE treatment:

Cycle 1

Remember To:

 
  • Tell your health care team about all of the other medications you are taking.

  • Keep taking other medications that have been prescribed for you, unless you have been told not to by your health care team.

You will have a blood test to check for hepatitis B before starting treatment. See the Hepatitis B and Cancer Medications pamphlet for more information.

How is this treatment given?

The medications in your treatment are given through an IV (injected into a vein) at the hospital.

You will have a blood test before each treatment cycle to make sure it is safe for you to get treatment.

What other medications are given with this treatment?

To Prevent Nausea and Vomiting

You will be given medications to help prevent nausea (feeling like throwing up) and vomiting (throwing up) before they start.

  • These are called anti-nausea medications and include medications such as ondansetron (Zofran®), granisetron (Kytril®), or others.

 

To Prevent Allergic Reaction and Swelling

Before docetaxel (DOCE), you will be given medication to help prevent allergic reactions and swelling.

  • The medication is a corticosteroid such as dexamethasone.

  • You will take the medication at home, starting 1 day before your docetaxel (DOCE) treatment. You will take it the day of your treatment and you will keep taking it after your treatment as well. 

  • The medication will help to prevent allergic reaction and swelling before they start.

 

To Prevent Infection

You may also be given a medication after each treatment day to increase your white blood cell count (neutrophils). This helps to prevent infection and make sure it is safe for you to get your next treatment.

  • Medications that increase your white blood cell count (neutrophils) may be called filgrastim (such as Neupogen®, Grastofil®, or others) or pegfilgrastim (such as Neulasta®, Lapelga®, or others).
  • Medications to prevent infections are called antibiotics (such as ciprofloxacin).
