“I had treatment last year and I want to give something back.”
A study looking at changing the order you have treatment for breast cancer (Neo-RT)
This study is looking at giving radiotherapy and then starting hormone therapy before having surgery to remove breast cancer.
This study is open to women with breast cancer that:
• has receptors for the hormone oestrogen (ER positive) and
• doesn’t have receptors for the protein HER2 (HER2 negative)
More about this trial
Doctors treat ER positive and HER2 negative breast cancer with surgery followed by radiotherapy and then hormone therapy.
Researchers think that having radiotherapy then hormone therapy before surgery might be better. As this could shrink the cancer and so the surgeon might be able to save more of the breast.
To find out whether it is better they need to do a clinical trial. Before doing a clinical trial they need to know that changing the order of treatment is possible and acceptable. This is a feasibility study.
The aims of this feasibility study are to see if:
- it is possible to change the order of treatment
- changing the order of treatment helps shrink the cancer, which would reduce the amount of surgery women need and so save more of the breast
Who can enter
The following bullet points list the entry conditions for this study. Talk to your doctor or the trial team if you are unsure about any of these. They will be able to advise you.
Who can take part
You may be able to join this study if you are a woman and the all of the following apply:
- you have invasive breast cancer that has receptors for the hormone oestrogen (ER positive) and does not have receptors for HER2 (HER2 negative)
- you are able to have breast conserving surgery
- your cancer measures 20mm or more and the doctor can feel the lump
- your cancer is slow growing (grade 1) or intermediate (grade 2), you might be able to take part if your cancer is fast growing (grade 3) and you are not suitable to have chemotherapy before surgery
- your doctor thinks that radiotherapy might make it easier for you to have breast conserving surgery
- you are up and about for at least half the day and can look after yourself (performance status 0, 1 or 2)
- are at least 18 years old
Who can’t take part
You cannot join this study if any of these apply. You:
- have cancer in both breasts
- have cancer that has spread to another part of the body (metastatic)
- have cancer in 2 or more areas of the breast and you cannot have breast conserving surgery
- are not able to have radiotherapy
- are not able to take hormone therapy after surgery
- have had another cancer in the past 5 years unless it was successfully treated and there hasn’t been any sign of it since
- have another medical or mental health condition that the doctor or study team think could affect you taking part
- are pregnant
- are breastfeeding
This is a feasibility study. The team need 43 women to join. You have treatment in this order:
- hormone therapy
You have radiotherapy once a day Monday to Friday for 3 weeks or once a week for 5 weeks. You have a radiotherapy planning session before starting radiotherapy. This is to plan where the radiographers need to give the radiotherapy. It is just like having radiotherapy without having the treatment.
You start hormone therapy the day after your last radiotherapy treatment. You take it for 20 weeks before surgery.
Women who haven’t gone through the menopause (premenopausal women) might have another drug called a gonadotropin-releasing hormone agonist (GnRH) with tamoxifen.
You then have surgery to remove the cancer.
Quality of life
You fill in a questionnaire before starting treatment and then:
- before your surgery
- 6 months after surgery
- every year for 5 years
The questions ask about:
- your general health
- any side effects or complications from treatment
- your daily activities
This is a quality of life questionnaire.
The trial team will ask you to have a research MRI scan:
- before starting treatment
- at the start of your radiotherapy
- at the end of your radiotherapy
- after starting hormone therapy
- before having surgery
This research MRI scan is the same as an MRI scan but it takes longer to do. The research MRI scan takes an hour. You don’t have to agree to have these scans. You can still take part in the main study.
Women from Cambridge will be asked to have a research PET-MRI scan that is similar to an ordinary PET-MRI scan but it takes longer to do. You have the scan:
- before starting treatment
- at the end of radiotherapy
The scan takes an hour and 15 minutes. You have a blood tests during the PET-MR scans. You don’t have to agree to have these scans done. You can still take part in the main study.
Tissue and blood samples
The team will also ask permission to take some cancer tissue samples (biopsies) and blood sample during the study. You don’t have to agree to these. You can still take part in the main study.
You see the doctor to have tests before taking part. These tests include:
- physical examination
- planning CT scan
- an MRI scan or PET-MRI scan (You have the research MRI scan or the research PET-MRI scan instead if you agreed to these.)
You have an MRI scan or the research MRI scan before surgery.
You see the doctor within a month after your surgery and then at:
- 3 months
- 6 months
- then once a year for 5 years
