TC is the name of a chemotherapy combination that includes:

  • docetaxel (also called Taxotere)
  • cyclophosphamide

It is a treatment for breast cancer.

How TC works

These chemotherapy drugs destroy quickly dividing cells, such as cancer cells.

How you have TC

You have taxotere and cyclophosphamide into your bloodstream (intravenously).

You might have treatment through a long plastic tube that goes into a large vein in your chest. The tube stays in place throughout the course of treatment. This can be a:

  • central line
  • PICC line
  • portacath

If you don't have a central line

You might have treatment through a thin short tube (a cannula) that goes into a vein in your arm. You have a new cannula each time you have treatment.

When you have TC

You usually have docetaxel and cyclophosphamide as cycles of treatment. This means that you have these drugs and then a rest to allow your body to recover.

You have up to 4 cycles. Each cycle lasts 3 weeks (21 days), so it takes about 3 months.

You have each cycle of treatment in the following way:

Day 1
  • You have docetaxel as a drip into your bloodstream over an hour.
  • You have cyclophosphamide as a slow injection into your vein.
Day 2 to 21
  • You have no treatment.

Then you start your next cycle of treatment.

Tests

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.

Side effects

How often and how severe the side effects are can vary from person to person. They also depend on what other treatments you're having.

When to contact your team

Your doctor, nurse or pharmacist will go through the possible side effects. They will monitor you during treatment and check how you are at your appointments. Contact your advice line as soon as possible if:

  • you have severe side effects
  • your side effects aren’t getting any better
  • your side effects are getting worse

Early treatment can help manage side effects better.

Contact your advice line immediately if you have signs of infection, including a temperature above 37.5C or below 36C.

We haven't listed all the side effects here. Remember it is very unlikely that you will have all of these side effects. But you might have some of them at the same time.

Common side effects

These side effects happen in more than 10 in 100 people (10%). You might have one or more of them. They include:

Increased risk of infection

Increased risk of getting an infection

is due to a drop in white blood cells. Symptoms include a change in temperature, aching muscles, headaches, feeling cold and shivery and generally unwell. You might have other symptoms depending on where the infection is.

Infections can sometimes be life threatening. You should contact your advice line urgently if you think you have an infection.

You may have injections (GCSF) to increase your white blood cells to help prevent infection.

Bruising, bleeding gums or nose bleeds

This is due to a

drop in the number of platelets in your blood

. These blood cells help the blood to clot when we cut ourselves. You may have nosebleeds or bleeding gums after brushing your teeth. Or you may have lots of tiny red spots or bruises on your arms or legs (known as petechiae).

Breathlessness and looking pale

You might be

breathless and look pale

due to a drop in red blood cells. This is called anaemia.

Loss of appetite and weight loss

You might not feel like eating

and may lose weight. Eating several small meals and snacks throughout the day can be easier to manage. You can talk to a dietitian if you are concerned about your appetite or weight loss.

Numbness of fingers and toes

Numbness or tingling in fingers or toes

is often temporary and can improve after you finish treatment. Tell your healthcare team if you're finding it difficult to walk or complete fiddly tasks such as doing up buttons.

Taste changes

Taste changes

may make you go off certain foods and drinks. You may also find that some foods taste different from usual or that you prefer to eat spicier foods. Your taste gradually returns to normal a few weeks after your treatment finishes.

Sore mouth

Mouth sores and ulcers

can be painful. It helps to keep your mouth and teeth clean, drink plenty of fluids and avoid acidic foods such as lemons. Chewing gum can help to keep the mouth moist. Tell your doctor or nurse if you have ulcers.

Diarrhoea

Contact your advice line if you have

diarrhoea

, such as if you've had 4 or more loose watery poos (stools) in 24 hours. Or if you can't drink to replace the lost fluid. Or if it carries on for more than 3 days.

Your doctor may give you anti diarrhoea medicine to take home with you after treatment. Eat less fibre, avoid raw fruits, fruit juice, cereals and vegetables, and drink plenty to replace the fluid lost.

Feeling or being sick

Feeling or being sick

is usually well controlled with anti sickness medicines. Avoiding fatty or fried foods, try eating small meals and snacks, drinking plenty of water, and relaxation techniques can all help.

It is important to take anti sickness medicines as prescribed even if you don’t feel sick. It is easier to prevent sickness rather than treat it once it has started.

Hair loss

You could

lose all your hair

. This includes your eyelashes, eyebrows, underarms, legs and sometimes pubic hair. Your hair will usually grow back once treatment has finished but it is likely to be softer. It may grow back a different colour or be curlier than before.

Skin changes

Skin changes

include darker skin and rashes, which may be itchy.

Tell your doctor if you have any rashes or itching. Don't go swimming if you have a rash because the chlorine in the water can make it worse.

If your skin gets dry or itchy, smoothing in unperfumed moisturising cream may help. Check with your doctor or nurse before using any creams or lotions. Wear a high factor sun block if you’re going out in the sun.

Nail changes

Your nails may become darker or lighter during treatment. They might also be painful, become loose and come off.

Fluid build up

A build up of fluid (oedema) may cause swelling in your arms, hands, ankles, legs, and other parts of the body. Contact your doctor if this happens to you.

Lack of energy and strength

This is usually mild. You can do things to help yourself, including some gentle exercise. It’s important not to push yourself too hard and eat a well balanced diet.

Talk to your doctor or nurse if this effect is stopping you from doing your usual daily activities.

Soreness, redness and peeling on palms and soles of feet

The

skin on your hands and feet may become sore, red, or may peel

. You may also have tingling, numbness, pain and dryness. This is called hand-foot syndrome or palmar plantar syndrome.

Moisturise your skin regularly. Your healthcare team will tell you what moisturiser to use.

Eye problems

You might have eye problems, including watery eyes and redness (conjunctivitis).

Let your doctor or nurse know if you have any problems with your eyes. They can give you eye drops to help.

If you get a high temperature, let your healthcare team know straight away. Ask them if you can take paracetamol to help lower your temperature.

Allergic reaction

A reaction may happen during the infusion. Symptoms can include a skin rash, itching, swelling of the lips, face or throat, breathing difficulties, fever and chills. Your nurse will give you medicines beforehand to try to prevent a reaction.

Tell your doctor or nurse immediately if at any time you feel unwell. They will slow or stop your drip for a while and give you medicine to help relieve your symptoms.

  • Find out more about the COVID-19 vaccine and cancer

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.
