Description of intervention(s) / exposure
This study looks at the association between endometrial cystic spaces found on ultrasound in women with abnormal uterine bleeding and either endometrial hyperplasia or endometrial cancer.
The consenting participants will answer a short (15 minute) online health questionnaire and undergo a transvaginal pelvic ultrasound (30 minutes) to determine the presence or absence of endometrial cysts. The scan will be performed or directly supervised by a senior O&G ultrasound specialist. Where possible this will be timed to occur on the same day as their endometrial sampling to avoid a further trip to hospital.
Participants will then have endometrial sampling (hysteroscopy dilatation and curettage) which is routinely a day procedure.

Statistical methods / analysis

All data will be assessed for normality. Groups will be summarised using mean and standard deviations for continuous variables and proportions (percentages) for categorical variables. Univariable logistic regression will be used to compare variables between participants with and without endometrial cysts, quoting crude odds ratios with 95% confidence intervals. When modelling for risk factors and potential confounders multivariable logistic regression will be performed. Potential confounders include BMI, unopposed oestrogen therapy, polycystic ovarian syndrome, personal history of breast, ovarian or bowel cancer, family history of breast, ovarian or bowel cancer, Lynch syndrome, BRCA mutation, tamoxifen use. Potential risk factors include Age, ethnicity, menopausal status, endometrial ablation, hormonal therapies, parity, type 2 diabetes, gestational diabetes, hypertension, family history of diabetes, heart disease, hypertension or stroke. Exploratory sub analysis will be performed dividing the group on menopausal status.

Summary
Brief summary
This study aims to determine if there is any association between endometrial cystic spaces identified on ultrasound and the incidence of endometrial hyperplasia (abnormal uterine cell growth that may or may not become cancerous), and the incidence endometrial cancer in women with abnormal uterine bleeding.

Who is it for?
You may be eligible for this study if you are aged 30 or older, have been diagnosed with abnormal uterine bleeding and you have been referred to the Royal Women's Hospital (Melbourne) for a hysteroscopy dilatation and curettage (HDC) procedure, or an endometrial biopsy.

Study details
All participants who choose to enrol in this study will be asked to complete a 15 minute online health questionnaire, and undergo a transvaginal pelvic ultrasound to determine the presence or absence of endometrial cysts. The ultrasound scan will be performed or directly supervised by a senior ultrasound specialist. Where possible this visit will be timed to occur on the same day as the hysteroscopy to avoid a further trip to hospital.

It is hoped this research may improve health outcomes by allowing for early identification of endometrial hyperplasia or cancer, which could have additional positive impacts on the future management of women with endometrial cysts.
