"I am glad that taking part in a trial might help others on their own cancer journey.”
A study looking for changes in PET-CT scans of women with ovarian, fallopian or primary peritoneal cancer that has come back
Please note - this trial is no longer recruiting patients. We hope to add results when they are available.
This study is looking for early changes that may show up in PET-CT scans of women with ovarian cancer, fallopian tube cancer or primary peritoneal cancer that has come back (relapsed).
As chemotherapy has side effects it is better to find out as soon as possible if the treatment is helping. If it is not working as well as the doctors hope, they can stop treatment or make changes, depending on the situation.
PET scans are a different type of scan. Doctors usually use these to measure the spread of cancer. They don’t currently use them to see how well chemotherapy is working
The researchers want to combine the PET scan and the CT scan into 1 scan called a PET-CT scan.
The aim of this study is to find out if a PET-CT scan is better than a CT scan alone at showing how well chemotherapy is working for women with relapsed ovarian, fallopian tube or primary peritoneal cancer.
Who can enter
You can enter this study if
- You have epithelial ovarian cancer, fallopian tube cancer or primary peritoneal cancer that has come back (relapsed) and can be seen on a CT scan
- You have had carboplatin or cisplatin (platinum drugs) before
- Your cancer has come back 6 months or more after you have had carboplatin or cisplatin
- You are having carboplatin or cisplatin again to treat your cancer
- You are well enough to take part in this trial (performance status 0, 1, 2)
- Your kidneys work well enough to take part in this trial
- You have gone through the menopause and have not had a period for 2 years OR you and your partner are willing to use reliable contraception if there is a chance you may become pregnant
- You are 35 years or older
You cannot enter this study if you
- Have had surgery to the tummy (abdomen) in the last 6 weeks
- Have had radiotherapy to the tummy or the area between your hips (pelvis) in the last 6 months
- Have a blockage in the bowel (bowel obstruction) that has not gone away
- Are having, or have had, another drug as a part of a clinical trial in the last 30 days before starting treatment in this trial
- Have diabetes that is not well controlled (your morning sugar level is greater than 8.3 mmol/L)
- Have another serious medical condition that could affect you taking part in this trial
- Are pregnant
Doctors hope to recruit 20 to 40 women into this study in 2 UK hospitals. Everyone taking part will have chemotherapy to treat their cancer.
In this study, everyone will have 4 or 5 PET-CT scans. You will have a scan
- Before you start chemotherapy
- After the 1st cycle of chemotherapy
- After the 2nd cycle of chemotherapy
- After you have finished chemotherapy
Those having 5 scans in total will have two scans before they start chemotherapy.
Two weeks after the last PET-CT scan, the researchers will telephone you to ask how you are.
You will have a CT scan after 3 cycles of chemotherapy. You would have this scan even if you were not taking part in this study.
You will have another CT scan 9 months after starting chemotherapy. This is for the researchers.
You will have 5 or 6 extra visits to the hospital as a part of this study. Each visit will last about 3 hours in total.
You have your first PET-CT scan a few days before you start chemotherapy. You cannot eat anything for 4 hours before the scan.
Firstly, you will have a fine needle put into a vein in your arm to give the radioactive ‘tracer’.
Before taking the scan, the researchers will take a small amount of blood to measure your blood sugar levels. If your blood sugar levels are too high, to give the radioactive ‘tracer’, the researchers will ask you to wait for a few hours.
This will be repeated each time you have a PET-CT scan.
There is a small amount of radioactivity in the tracer injection for the PET-CT scan. But this shouldn’t cause any side effects.
The ‘contrast’ dye for the CT scan may cause some side effects including itching, flushing and a metallic taste in your mouth.
