Description and study of the steroid Metabolome in mucinous ovarian cancer

This study is open to women aged 18 or over. It's important that you understand the study and agree to take part. There are three different parts, and who can join depends on your current health situation.

For the first part, you might be eligible if you are having surgery for a growth on your ovary, or if you have recently been diagnosed with mucinous ovarian cancer and haven't started treatment yet. For the second part, you might be able to join if you have finished your first round of treatment for mucinous ovarian cancer.

Finally, for the third part, you could be eligible if you have a condition called pseudomyxoma peritonei or certain types of appendiceal (bowel) cancers. There are also specific reasons why you might not be able to join, such as if you've recently used hormonal contraception, hormone replacement therapy, or steroid treatments.

If you decide to take part, you'll first receive a detailed information sheet about the study, and everything will be explained clearly. If you're happy to go ahead, you'll sign a consent form. Then, you'll answer some questions about yourself and your health.

The main thing you'll be asked to do is collect all your urine over a 24-hour period, in your own home, at a time that suits you. You'll be given a special bottle for this. This urine sample will then be collected when you next visit the hospital.

If you're in the first or third part of the study, you'll only need to do this urine collection once. If you're in the second part of the study, you'll be asked to collect urine about every three months for two years. The researchers will try to arrange these collections to fit in with your regular hospital appointments, so it should be as convenient as possible.
