False
- post menopausal women
Endometrial cancer typically infiltrates ______
Myometrium
Peak incidence occurs in which age group?
50-60 year olds

Endometrioid carcinoma
Serous carcinoma
What is the main risk factor for endometrial cancer?
Obesity
Sex hormone binding globulin levels are HIGHER/LOWER in obese women?
Lower
Why is obesity a risk factor for endometrial cancer?
Adipocytes express aromatase.
Aromatase converts ovarian androgens -> oestrogens.
Increased level of oestrogen induces endometrial proliferation.
Which condition is associated with endometrial cancer?
Lynch syndrome
Endometrial cancer - clinical features
Abnormal bleeding
- post menopausal bleeding
Endometrial cancer - investigations
Transvaginal US - assess thickness of endometrium MRI scan - assess degree of myometrial invasion CT scan - looks for distal nodal mets
Endometrial cancer - how many stages are there
4
Endometrial cancer - stage I
Confined to uterus
Ia - less than 50% myometrial invasion
Ib - over 50% myometrial invasion
Endometrial cancer - stage II
Tumour invades cervical stroma
Endometrial cancer - stage III
Local and/or regional tumour spread
Endometrial cancer - stage IV
Tumour invades bladder and/or bowel mucosa and/or distant metastases
Endometrial cancer - management if the tumour has not invaded?
Hysterectomy
Endometrial cancer - management options
Surgery - hysterectomy
Radiotherapy
Chemotherapy
