Q

What is the main cause of cervical cancer?

A

High risk HPVs: HPV16, HPV18

Dysplasia of squamous cells in cervical epithelium, induced by HPV infection

9
Q

How is CIN staged?

A

CIN I progressing to CIN II progressing to CIN III which can become invasive carcinoma

10

Q

Where is invasive cervical carcinoma likely to spread?

A

Cervical, pelvic and para-aortic nodes

Bladder, uterus , rectum and vagina

14
Q

How is invasive cervical carcinoma treated?

A

Microinvasive - cervical cone excision

Invasive - hysterectomy, LN dissection (radio and chemo if advanced)

15
Q

What is the typical presentation of invasive cervical carcinoma?

A

Screening abnormality or vaginal bleeding

16
Q

What is the precursor to endometrial adenocarcinoma?

A

Endometrial hyperplasia

17
Q

What are some causes of endometrial adenocarcinoma?

A

Prolonged oestrogen: anovulation, adipose causing oestrogen secretion (obesity) and exogenous oestrogen

18
Q

How does endometrial adenocarcinoma present and at what ages?

A

Usually 55-75

Irregular or post-menopausal vaginal bleeding

19
Q

What is the treatment for endometrial adenocarcinoma?

A

Hysterectomy

20
Q

What are the types of endometrial adenocarcinoma?

A

Endometrioid, serous carcinoma

21
Q

Describe endometrioid endometrial adenocarcinoma: (include where it spreads)

A

Mimics proliferative glands

Spread by myometrial invasion to cervix, bladder and rectum, local LNs and distant sites

22
Q

Describe serous endometrial adenocarcinoma: (include where it spreads)

A

Poorly differentiated, exfoliates and travels through Fallopian tubes to peritoneal surfaces

23
Q

What are some tumours of the myometrium?

A

Leiomyoma (fibroids)

Leiomyosarcoma

24
Q

How does leiomyoma present?

A

Heavy/painful periods, urinary frequency, infertility (can be asymptomatic)

25
Q

When is leiomyosarcoma likely to present?

A

40-60

26
Q

Where does leiomyosarcoma commonly metastasise to?

A

Lungs

27
Q

When do ovarian tumours commonly present?

A

Benign: 20-45
Malignant: 45-65

28
Q

Generally, how do ovarian tumours present?

A

Abdominal pain, distension, urinary and GIT symptoms, ascites, intestinal obstruction

29
Q

What is the marker for ovarian tumours?

A

Serum CA-125

30
Q

How can ovarian tumours be classified?

A

Mullerian epithelium
Germ cells
Sex cord stromal cells
Metastasis

31
Q

What are the types of epithelial ovarian tumours?

A

Serous, mucinous or endometrioid

32
Q

What are the risk factors for developing epithelial ovarian tumours?

A

Nulliparity, OCP is protective, heritable mutations (BRCA), smoking, endometriosis

33
Q

Describe serous epithelial ovarian tumours:

A

Spread to peritoneal surfaces and omentum, associated with ascites

34
Q

Describe mucinous epithelial ovarian tumours:

A

Large, cystic mass with sticky fluid, often benign or borderline

35
Q

Describe endometrioid epithelial ovarian tumours:

A

With tubular glands like endometrium, can be due to endometriosis

36
Q

What is pseudomyoxma peritonei?

A

Originating from appendix, cancer cells that produce mucus and mucinous ascites. Often involves the ovaries and colon
