Q

What do you do if the smear result is moderate dyskarosis?

A

Refer to colposcopy

19
Q

What do you do if the smear result is severe dyskarosis?

A

refer to colposcopy

20
Q

What do you do if the smear result shows glandular abnormalitis

A

refer to colposcopy

21
Q

What do you do if the smear result shows invasive cancer?

A

Urgent (within 2 week) referral

22
Q

How is acetic acid used in colposcopy?

A

Goes white with any abnormality and shows the extent of the lesion

23
Q

How is iodine used in colposcopy?

A

Goes brown in a normal cervix. If there is an absence of a stain it is abnormal

24
Q

What is cold coagulation of the cervix?

A

A hot probe which causes cells to burst

25
Q

What is LLETZ?

A

An electrosurgical technique where wire can cut through the loop of tissue

26
Q

How are people who have had a LLETZ/cold coagulation followed up after?

A

Test of cure which is a combined smear and HPV test after 6 months. If they are both negative then it is just 3 yearly repeat smears. If positive need further colposcopy

27
Q

What is the most common type of cervical cancer?

A

Squamous cell carcinoma

28
Q

How long does it take to go from HPV infection to high grade CIN to invasive cancer?

A

HPV –> High grade CIN: 6 months - 3 years

High grade CIN –> Invasive cancer: 5 - 20 years

29
Q

What part of the cervix does cervical cancer occur?

A

Transformational zone

30
Q

What does koilocytosis indicate on a cervical smear?

A

HPV infection

31
Q

What does CIN look like histologically?

A

Immature basal cells occupy more of the epithelium
Nuclear abnormalities
Excess mitotic activity

32
Q

What is meant by CIN1?

A

Basal 1/3rd of epithelium occupied by abnormal cells

33
Q

What is meant by CIN2?

A

Abnormal cells extend to middle 1/3rd

34
Q

What is meant by CIN3?

A

Abnormal cells occupy full thickness of the epithelium.

35
Q

Where does cervical glandular neoplasia originate from?

A

Endocervical epithelium

36
Q

Which type of HPV is particularly associated with adenocarcinoma?

A

HPV 18

37
Q

What is the most important prognostic factor for vulval squamous carcinoma?

A

Spread to inguinal lymph nodes

38
Q

What are the main two types of endometrial carcinoma? What are the main differences?

A
Endometriod adenocarcinoma (Type 1) 
- Oestrogen dependant 
- Younger women 
- Good prognosis 
Serous papillary carcinoma ( Type 2) 
- Non oesterogen dependent 
- Elderly women 
-   Poorer prognosis
39
Q

What endometrial thickness on biopsy is suggestive of endometrial cancer?

A

Over 4mm

40
Q

What is the main precursos for endometriod carcinoma?

A

Atypical hyperplasia

41
Q

What is the precursos for serous carcinoma?

A

Serous intraepithelial carcinoma

42
Q

What mutations are associated with endometrial type 1 tumours?

A

Atypical hyperplasia is the precursor
Microsatellite instability
Lynch syndrome - germline mutation of mismatch repair genes

43
Q

What does obesity cause endometrial cancer?

A

Adipocytes convert ovarian androgens into oestrogens with cause endometrial proliferation
SHBg is lower in obese women so free levels of the hormones are higher

44
Q

What gene mutation is associated with serous and clear cell cancer?

A

TP53 mutation and over expression
