Background and study aims
Ovarian cancer is the main cause of death from gynaecological malignancies in the UK. Despite massive funding in developing drugs and new treatment strategies, survival rates remain much poorer when compared to other cancers with 3 in 10 women alive at 10 years. In addition, 1 in 10 of all ovarian cancer is familial and most commonly caused by a fault/alteration in the BRCA1 or BRCA2 gene. BRCA1/BRCA2 carriers have a 17-44% risk over their life of developing ovarian cancer and 65-72% risk of developing breast cancer. This is much higher than for women who do not carry the gene who have a 1 in 50 (2%) and a 1 in 8 (12%) lifetime risk of developing ovarian and breast cancer respectively. Focusing on developing strategies to prevent ovarian cancer in women at increased risk may have a significant impact on disease burden. There is currently no screening programme for ovarian cancer available on the NHS unlike other female cancers such as cervical and breast cancer. The current practice is to offer women who are at increased risk, once they have completed their family, surgery to remove their fallopian tubes and ovaries. This procedure is called risk reducing salpingo-oophorectomy (RRSO). This significantly reduces the risk of ovarian cancer by 90% but leads to early menopause. This has serious implications on a woman's general health. Not only does early menopause result in menopausal type symptoms such as hot flushes, changes in mood and pain during intercourse, it also increases the risk of osteoporosis (brittle bones), heart disease, stroke and dementia. Current research suggests that many cancers of the ovary actually start in the fallopian tube. This has led to the proposal of an alternative strategy which involves offering women surgery in two stages. The first operation involves removing the fallopian tubes. The second operation involves removing the ovaries after the patient has gone through the menopause (average age 51 in the UK). The advantage of this new surgical prevention strategy is that it offers some protection against ovarian cancer in young women whilst avoiding the negative health consequences of early menopause which can have a significant impact on quality of life. At present the precise level of benefit obtained from removing the tubes alone is not known. There are no research studies to show whether this two-stage procedure is acceptable and effective for preventing ovarian cancer. Further research is needed to establish this. The aim of this study is to collect the views of women at increased risk on this ‘two-stage’ strategy to prevent ovarian cancer.

Who can participate?
Women aged over 18, living in the UK who are at increased risk of developing tubal/ovarian cancer because they carry an alteration/fault in the BRCA1/BRCA2/RAD51C/RAD51D/BRIP1 gene or have a strong family history of breast and ovarian cancer or ovarian cancer alone

What does the study involve?
Participants complete an online or paper questionnaire to gather information about their attitudes towards the two-staged surgical approach to reduce the risk of ovarian cancer. The questionnaire is conducted just once per participant. There are no follow up questionnaires.

What are the possible benefits and risks of participating?
Participants will help researchers understand how women feel about this new two-staged surgical approach of preventing ovarian cancer. It will help develop future research studies for ovarian cancer prevention and benefit the health of women at increased risk of ovarian cancer in the future. The drawback to participating is the inconvenience of completing a questionnaire.

Scientific titleSurvey to determine attitudes of women at high risk of ovarian cancer towards Risk Reducing Early Salpingectomy and Delayed Oophorectomy (RRESDO) for ovarian cancer prevention
Study objectivesRisk reducing early salpingectomy with delayed oophorectomy is an acceptable surgical prevention strategy for women who are at increased risk of ovarian cancer.
Ethics approval(s)West Midlands - Edgbaston Research Ethics Committee, 21/08/2017, REC ref: 17/WM/0324
Health condition(s) or problem(s) studiedPrevention of ovarian cancer
InterventionParticipants who have met the study's inclusion/exclusion criteria and who have provided informed consent will be given a questionnaire to complete. This will gather information about their attitudes towards a novel two staged surgical approach (risk reducing early salpingectomy with delayed oophorectomy) to reduce the risk of ovarian cancer. The questionnaire may be completed online or using a paper version. The questionnaire is conducted just once per participant. There are no follow up questionnaires.
Intervention typeOther
Primary outcome measureAwareness and interest in an early salpingectomy and delayed oophorectomy strategy for ovarian cancer prevention, measured using a questionnaire at a single timepoint
Secondary outcome measuresThere are no secondary outcome measures
