Endometrial ca Flashcards
What is the cause of endometrial carcinoma?
The prolonged exposure to oestrogen which causes unopposed endometrial proliferation and hyperplasia which can lead to carcinoma
What are the two types of endometrial carcinoma?
Type 1-caused by prolonged oestrogen stimulation
Type 2-more familial association and caused by strophic endometrium
What are the risk factors for developing endometrial carcinoma?
- Obesity-conversion of androgens to oestrogen
- Nulliparity and infertility because of increased exposure to oestrogen
- Late menopause-after 52 years and early menarche
- HRT-Make sure the women takes progesterone for a minimum of 11 days to combat the oestrogen
- Women with PCOS-anovulatory
- Family history of Lynch syndrome
- Tamoxifen use in breast ca patients
- Hypertension, DM
What is the normal menstrual cycle?
Proliferation phase with oestrogen and the secretory phase with progesterone
What is the most common histology of endometrial ca?
Adenocarcinoma 60-80%
What are the histological types of endometrial ca?
- Adenocarcinoma
- Adenocarcinoma with squamous hyperplasia
- Clear cell carcinoma which originates from the Müllerian ducts
What are the symptoms of endometrial ca?
- Post-menopausal bleeding-any PMB is malignant until proven otherwise
- Vaginal discharge purulent caused by infection of the tumour itself
- Pain which is a late sign
What is the spread of the ca?
- Direct spread
- laterally: endometrium, myometrium, adnexa, abdomen
- vertically: cervical glands to the vagina wall
- anteriorly/posteriorly: bladder, pouch of Douglas
What is the lymphatic spread of the ca?
If the carcinoma is more in the fungus it will be in the para-aortic LN
If the carcinoma is in the pelvic area- External iliac, internal iliac, obturator
What is the haematogenous spread?
It is a late sign but Mets to the lungs, liver, bones and brain
What examinations do you do in a patient with endometrial ca?
- Speculum
- Bimanual vaginal exam
- Rectal exam
- Transvaginal ultrasound: >5mm biopsy <5mm follow up
