A

20-30%

42
Q

From what cell type does adenocarcinoma of the cervix develop?

A

Columnar epithelium

43
Q

Cysts under what size in pre-menopausal women don’t require F/U?

A

50mm - will resolve within 3 cycles

44
Q

What should the F/U of simple cyst between 50 and 70mm be?

A

F/U in 1 year - if not resolved, consider operative management

45
Q

Group II ovulation disorders account for what % of ovulation disorders?

A

80-85%

46
Q

PCOS accounts for what % of anovulatory infertility?

A

75%

47
Q

What is the hormonal profile in PCOS?

A

Normal gonadotrophins
Normal oestrogen
Increased testosterone
Decreased SHBG

48
Q

How do Nabothian follicles come about?

A

Benign, mucus containing cysts trapped within the cervical transformation zone

Occur following squamous metaplasia of columnar epithelium

49
Q

What factors decrease the risk of ovarian Ca?

A

Oral contraceptive use
Higher Parity
Breast feeding
Hysterectomy
Tubal Ligation
Statins
SLE

50
Q

What factor increases the risk of ovarian Ca?

A

HRT

51
Q

What are the features of mucinous cyst adenomas?

A

Usually large
Multilocular
Thin walled septa
Locules may vary in echogenicity due to variation in fluid content

52
Q

What are the features of serous cyst adenomas?

A

Usually unilocular

53
Q

What is the origin of an ovarian dermoid cyst?

A

Purely ectodermal in origin, so contains dermal and epidermal elements

54
Q

What is the origin of an ovarian mature cystic teratoma?

A

Tissue can arise from any of the three germ cell layers (mesoderm, endoderm and ectoderm). Normally 2 of the 3 are seen

55
Q

What are the features of ovarian fibromas?

A

BENIGN
Ascites
Solid, hypo echoic mass on USS
A type of sex-cord stromal tumour
Histological appearances include spindle cells and collagen

56
Q

What are the features of thecomas?

A
  • Sex cord-stromal tumour, arising from theca cells
  • Almost always benign
  • USS features are variable, may be hypoechoic, solid or mixed
  • Most common in postmenopausal women
  • Oestrogen secreting so cause endometrial hyperplasia resulting in post-menopausal bleeding –> high risk for endometrial cancer
57
Q

Aside from thecomas, what type of tumours are also oestrogen secreting?

A

Granulosa cell tumours (although not always benign, unlike thecomas)

58
Q

An RMI of what suggests need referral for specialist MDT (according to NICE)?

A

> 250

58

How are PCO defined on USS?

A

One or both ovaries with 12 or more follicles (with a diameter of 2-9mm) or an ovarian volume greater than 10cm-cubed

59
Q

How is RMI - RMI = U x M x Ca-125 - calculated?

A

USS features (1 point for each)
- Multilocular cysts
- Solid areas
- Metastases
- Ascites
- Bilateral lesions

USSscore:
0 points = 0
1 point = 1
2-5 points = 3

Menopausal status
Pre-menopausal = 1
Post-menopausal = 3

60
Q

What is the lifetime risk of ovarian cancer?

A

2% - leading cause of death from gynaecological cancer

61
Q

What is the 5 year survival for ovarian cancer?

A

35%

62
Q

A Ca-125 > than what warrants further investigation?

A

35

63
Q

In women <40 with suspected ovarian cancer, what other tumour markers should be requested?

A

Alpha fetoprotein (AFP)
Beta human chorionic gonadotrophin (beta-hCG) Serum CA125

64
Q

What size hysteroscopes should be used in outpatients?

A

2.7mm with a 3–3.5mm sheath

65
Q

What can be used for endometrial protection/withdrawal in oligo/amenorrhoea in PCOS?

A

A cyclical progestogen, such as medroxyprogesterone 10 mg daily for 14 days every 1–3 months
CHC
LNG-IUS

If unacceptable, regular USS 6-12 monthly may be required for surveillance

66
Q

What additional antenatal considerations should be given for women with PCOS?

A

An OGTT, ideally pre-conceptually, but also before 20 weeks, and again 24-28 weeks

66
Q

What surveillance should be in place for those with endometrial hyperplasia without atypia?

A

6-monthly
2 consecutive 6-monthly negative biopsies required prior to discharge
In those with high risk of recurrence, e.g. high BMI, consider annual biopsy

67
Q

In whom with endometrial hyperplasia without atypia, may hysterectomy be indicated?

A

Not wanting to preserve their fertility and:
1. When progression to atypical hyperplasia occurs during F/U

  1. There is no histological regression of hyperplasia
    despite 12 months of treatment
  2. There is relapse of endometrial hyperplasia after completing progestogen treatment
  3. There is persistence of bleeding symptoms
  4. The woman declines to undergo endometrial surveillance or comply with medical treatment
68
Q

In women with endometrial hyperplasia WITH atypia, whom decline hysterectomy, what should their F/U be?

A

Review intervals should be every 3/12 until 2 consecutive negative biopsies are obtained
