Find out what CHOP is, how you have it and other important information about having CHOP.
CHOP is the name of a combination of cancer drugs used to treat non-Hodgkin lymphoma (NHL) and chronic lymphocytic leukaemia (CLL). It is made up of the drugs:
- doxorubicin (Adriamycin)
- vincristine (Oncovin)
- prednisolone, which is a steroid
How it works
These chemotherapy drugs destroy quickly dividing cells, such as cancer cells.
How you have it
You have cyclophosphamide, vincristine and doxorubicin into your bloodstream (intravenously). You have prednisolone (steroid) as tablets you take with or after food.
Drugs into your bloodstream
You have the treatment through a drip into your arm or hand. A nurse puts a small tube (a cannula) into one of your veins and connects the drip to it.
You might need a central line. This is a long plastic tube that gives the drugs into a large vein, either in your chest or through a vein in your arm. It stays in while you’re having treatment, which may be for a few months.
Taking your tablets
You should take the right dose, not more or less.
Talk to your specialist or advice line before you stop taking a cancer drug.
When you have it
You have CHOP chemotherapy in cycles of treatment. Each cycle of treatment lasts 21 days (3 weeks). You may have 6 to 8 cycles of treatment in total.
You have each cycle in the following way:
- You have cyclophosphamide as a drip into your bloodstream (intravenously) over 30 minutes
- You have doxorubicin as a slow injection into your vein
- You have vincristine as a drip into your bloodstream over 5 minutes
- You take prednisolone tablets
- You take prednisolone tablets
- You have no treatment
You then start the next cycle of treatment.
You have blood tests before and during your treatment. They check your levels of blood cells and other substances in the blood. They also check how well your liver and kidneys are working.
Other medicines, food and drink
Cancer drugs can interact with some other medicines and herbal products. Tell your doctor or pharmacist about any medicines you are taking. This includes vitamins, herbal supplements and over the counter remedies.
Pregnancy and contraception
This treatment might harm a baby developing in the womb. It is important not to become pregnant or father a child while you're having treatment and for a few months afterwards. Talk to your doctor or nurse about effective contraception before starting treatment.
You may not be able to become pregnant or father a child after treatment with this drugs. Talk to your doctor before starting treatment if you think you may want to have a baby in the future.
Men might be able to store sperm before starting treatment. And women might be able to store eggs or ovarian tissue. But these services are not available in every hospital, so you would need to ask your doctor about this.
Don’t breastfeed during this treatment because the drugs may come through in your breast milk.
Treatment for other conditions
Always tell other doctors, nurses, pharmacists or dentists that you’re having this treatment if you need treatment for anything else, including teeth problems.
Don’t have immunisations with live vaccines while you’re having treatment and for up to 12 months afterwards. The length of time depends on the treatment you are having. Ask your doctor or pharmacist how long you should avoid live vaccinations.
In the UK, live vaccines include rubella, mumps, measles, BCG, yellow fever and the shingles vaccine (Zostavax).
- have other vaccines, but they might not give you as much protection as usual
- have the flu vaccine (as an injection)
Contact with others who have had immunisations - You can be in contact with other people who have had live vaccines as injections. Avoid close contact with people who have recently had live vaccines taken by mouth (oral vaccines) such as the oral typhoid vaccine.
If your immune system is severely weakened, you should avoid contact with children who have had the flu vaccine as a nasal spray. This is for 2 weeks following their vaccination.
Babies have the live rotavirus vaccine. The virus is in the baby’s poo for about 2 weeks and could make you ill if your immunity is low. Get someone else to change their nappies during this time if you can. If this isn't possible, wash your hands well after changing their nappy.
