This study looked at how many women with womb cancer have Lynch syndrome. This is a condition that can run in families. If you have Lynch syndrome, you have a higher risk of developing some cancers.
The study was open for people to join between 2015 and 2017. The team first published results in 2019.
More about this trial
There are several factors that can increase someone’s risk of developing womb cancer. These include:
- getting older
- being overweight
- not having children
- inherited genetic changes
Lynch syndrome is when people have inherited certain genetic changes from their parents.
People who have Lynch syndrome have an increased chance of developing some cancers. This includes womb cancer, ovarian cancer and bowel cancer. You may hear Lynch syndrome being called hereditary non polyposis colon cancer, or HNPCC.
Researchers wanted to find out how many women with womb cancer had Lynch syndrome. And how those women felt about being tested for it.
The main aims of this study were to find out:
- how many women with womb cancer have Lynch syndrome and how best to identify them
- whether women with womb cancer want to be tested for Lynch syndrome
- whether it is cost effective for the NHS to test women with womb cancer for Lynch syndrome
Summary of results
The research team found that it is important to offer testing for Lynch syndrome to all women who have womb cancer.
Study design
This study was for women in the Manchester area who had been diagnosed with womb cancer.
They completed a questionnaire about their health, lifestyle and family history. And the research team looked at tissue and blood samples for genetic changes.
Anyone who was found to have Lynch syndrome was given advice and support. They were also offered regular screening for bowel cancer.
Results
A total of 500 women took part in this study. Tests showed that 16 of them (3%) had Lynch syndrome.
The researchers concluded that it was cost effective to offer all women with womb cancer a test for Lynch syndrome. They recommended that all women with womb cancer should be routinely offered testing.
Following this research, in 2020, NICE recommended that all women diagnosed with womb cancer should be offered a test for Lynch syndrome. If they do have Lynch syndrome, their relatives can be tested as well.
