Q

What is a precursor to endometrial carcinoma? What is it associated with?

A

Endometrial hyperplasia
Increased gland to stroma ratio
Associated with prolonged oestrogen stimulation:
Annovulation

19
Q

What is the most common cancer of the female genital tract

A

Endometrial adenocarcinoma

20
Q

How does endometrial adenocarcinoma present? When?

A

Irregular or postmenopausal bleeding

55-75 - perimeopausal and older

21
Q

What are the types of endometrial adenocarcinoma?

A

Endometrioid
Mimics proliferative glands
Typically arises in setting of endometrial hyperplasia
Spreads by myometrial invasion and direct extension

Serous
Poorly differentiated, aggressive, worse prognosis
Exfoliates, travels through Fallopian tubes, implants on peritoneum

22
Q

What causes endometrial adenocarcinoma in perimenopausal women?

A

Unopposed oestrogen from obesity
Exogenous oestrogen
Hormone secreting tumour
Tamoxifen (used to treat breast cancer)

23
Q

What are some risk factors of endometrial adenocarcinoma?

A

Early menarche, late menopause and few pregnancies - high oestrogen exposure
Obesity may produce oestrogen from androgens through adipose

24
Q

What is fibroid?

A

Leiomyoma

Benign tumour of uterine smooth muscle

25
Q

Symptoms of fibroids

A

Heavy menstrual loss and intermenstrual bleeding, pain, discharge and infertility.

26
Q

Are fibroids malignant? What does growth depend on?

A

No
Oestrogen
Regress after menopause

27
Q

What is leimyosarcoma?

A

Malignant tumour of myometrium

Infiltrate locally with metastasis by the blood stream to lungs and then systemically

28
Q

What are the symptoms of ovarian tumours? When do they occur?

A
Abdo pain
Abdo distension
Urinary/GI
Ascites
Menstrual disturbances
When they become large, invade adjacent structures or metastasise
29
Q

What can ovarian tumours arise from?

A

Mullerian epitehlium
Germ cells
Sex cord stroma
Metastases

30
Q

What are the risk factors for ovaria cancer?

A

Low parity
BRAC1/BRCA2 mutations
Smoking
Endometriosis

OCP is protective

31
Q

What is pseudomyoma peritonei

A

Cancer that begins as a polyp in the appendix and spreads through the wall.
Extensive mucinous ascites
Epithelial implants on peritoneal surfaces
Frequent involvement of ovaries
Intestinal obstruction

32
Q

What are teratoma?

A

Germ cell tumours that contain tissue from more than one germ layer:
skin hair teeth bone neural

33
Q

What does the presence of immature tissue indicate?

A

Risk for intra-abdominal spread

34
Q

What tumour markers are for non-gestational choriocarcinoma?

A

hCG

35
Q

What tumour marker is for yolk sac tumour

A

alpha fetoprotein

36
Q

What is the significance of sex cord tumours?

A

Commonly produce oestrogen’s and may be responsible for endometrial adenocarcinoma and isosexual precocious pubertyWHAT ARE THECOMAS?

37
Q

What are the comas?

A

Benign tumours derived from the ovarian stroma

May produce oestrogen.

38
Q

What do ovarian sertoli-leydig cells cause?

A
Defeminisation, amenorrhoea
Infertility
Breast atrophy
Hair loss
Hirsuitism
Clitoral hypertrophy
39
Q

What is high hCG associated with?

A

Gestational tumours.

40
Q

Give 3 gestational tumours

A

Hydatidiform mole
Invasive mole
Choriocarcinoma

41
Q

What do hydatidiform moles result from? What are they associated with? Presentation? Treatment?

A

Result from chromosomal defect in conceptus causing oedema of placental chorionic villi.
Associated with atypical trophoblastic hyperplasia - have potential for myometrial penetration.
Can present with miscarriage
Treated with curettage.

42
Q

How does invasive mole present? How is it differed from hydatidiform mole? Treatment

A

Penetrates uterine wall
Vaginal bleeding and uterine enlargement
Persistent elevated hCG
Treated with chemotherapy

43
Q

What is choriocarcinoma?
Presentation
Treatment

A

Malignant tumour of placenta composed of syncytiotrophoblast and cytotrophoblast without villi.
hCG levels high
Presents with vaginal spotting
Treated with uterine evacuation and chemo
