Q

CIN is the precursor lesion of invasive cancer, how is it graded?

A

Via biopsy:

CIN1: dyskaryosis in basal 1/3rd
CIN2: dyskaryosis in 2/3rds of epithelium
CIN3: full thickness dyskaryosis

Q

When do we intervene in management of CIN?

17
Q

What management do we offer for CIN 2/3?

A

cold coagulation

LLETZ: large loop excision biopsy

18
Q

When do we use LLETZ?

A

when woman has no intention of further pregnancy

as risk of cervical incompetence and preterm labour/miscarriage

19
Q

If CIN 1 identified on colposcopy what do we do?

A

Repeat smear in 12 months

20
Q

If smear found a glandular abnormality (gCIN) what do we do?

A

Send them directly for LLETZ

as possible risk of adenocarcinoma of the endocervix

21
Q

After treatment how do we test to see if its been effective?

A

repeat smear at 6 months

oncogenic HPV tested for too

22
Q

If cervical cancer is diagnosed what is the management?

A

Stage 1a: cone biopsy
Stage 1a2 - 2a: radical hysterectomy with bilateral pelvic node dissection
Stage 2b-4: radiotherapy +/- chemotherapy

23
Q

How can we prevent cervical cancer?

A

HPV vaccine

regular smear tests (screening)

24
Q

What are the 3 types of endometrial hyperplasia?

A

simple (0% risk of ca)
complex (1-2% risk of ca)
atypical (20% risk of ca)

25
What type of tumour are endometrial cancers?
majority adenocarcinoma 80% arise from hyperplasia - endometriod 20% dont arise from hyperplasia - squamous and clear cell other types: stromal sarcoma, carcinocarcinoma, leiomyosarcoma
26
How may someone with endometrial cancer present?
PMB abnormal intermenstrual bleeding menorrhagia
27
How do we assess suspected endometrial cancer?
``` PV + speculum TVU endometrial biopsy (pipelle) hysteroscopy staging (MRI) CTCAP ```
28
On TVU what thickness of endometrium is suspicious for endometrial cancer?
post menopausal >4mm | pre menopausal >16mm
29
How might someone with ovarian cancer present?
often vague symptoms for a few months: ``` SoB Fatigue, weight loss Urinary freq/urgency irregular bleeding/pelvic pain abdo pain, bloating, early satiety, reduced appetite change in BO ascited ```
30
How do we investigate for ovarian cancer?
``` Blood: tumour markers CA125 Imaging: 1st line TVUS Tissue sampling: ascetic tap (cytology) laparotomy/laparoscopy for biopsy ```
