A study looking at the structure of the body and how it affects treatment side effects (CANDO-3)

Cancer type:

Breast cancer

Status:

Open

Phase:

Other

This study is looking at the amount of muscle and fat in the body and how it might affect the side effects of chemotherapy. 

It is open to women with early breast cancer Open a glossary item that has grown into the breast tissue (invasive breast cancer Open a glossary item).

More about this trial

Chemotherapy is one of the main treatments for breast cancer. To work out how much chemotherapy you have doctors take your height and weight. 

However the structure of everyone’s body is different and not everybody has the same amounts of muscle and fat. Having less muscle, but with more fat, has been linked to being less able to tolerate chemotherapy. This could make a difference to how bad the side effects of chemotherapy might be. 

Using a machine that is like advanced bathroom scales the team can now assess the amount of muscle and fat in your body.   

In this study the team use the machine before each of your chemotherapy treatments.

They will also ask you about any side effects that you might have had from the previous treatment.

The main aim of the study is to find out whether the differences in the amount of muscle and fat in the body can affect how bad chemotherapy side effects might be. 

Please note you might not benefit directly from taking part in this study but the information gained could help people in the future who are having chemotherapy.

  • have any other medical condition that could affect you taking part
  • have a pacemaker

Trial design

The study team need 300 women to take part. 

Taking part does not affect your chemotherapy treatment at all. 

You see a member of the study team before each cycle of treatment Open a glossary item. They take measurements such as your weight and grip strength. You also stand on a machine that takes more detailed measurements of the structure of your body.

This is a Seca body analysis machine. It is like a big digital set of weighing scales with hand grips on the side to hold on to. You take off your shoes and socks to stand on the machine. You need to stay still for 75 seconds while it takes the measurements. The team member will tell what you need to do and how. 

Participant on the study measuring machine

The team ask your doctor at the hospital a few questions about your treatment. They also look at your medical records. They might also ask to look at the results of any CT scans Open a glossary item you might have as part of your treatment. 

Questionnaires
You fill in some questionnaires before you start your treatment then:

  • half way through your course of treatment
  • at the end of treatment
  • 3 months after you finish treatment

The questions ask about your lifestyle and general health. The research team will also ask about any side effects that you might have had. This takes about 20 minutes to do.

Hospital visits

The team will try their best to see you only when you are coming to the Hospital to see your cancer doctors and nurses or to have your treatment.

The  research study visits before each treatment take about 20 minutes.

Side effects

There are no side effects from taking part in the study.

Each type of chemotherapy treatment has its own side effects. Your doctor will talk to you about the possible side effects of your treatment. 

We have information about general side effects of chemotherapy.
