A

Elderly

26
Q

What is the most common type of sex cord stromal tumour’

A

27
Q

What is Ca 125 a marker for?

A

Epithelial ovarian cancer (serous)

28
Q

What is Ca 19-9 a marker for=

A

Epithelial ovarian cancer (mucinous)

29
Q

What is inhibin a marker for?

A

Sex cord stromal tumour (granulose cell)

30
Q

What is beta HCG a marker for ?

A

Germ cell tumour

- choriocarcinoma, dysgerminoma

31
Q

What is AFP a marker for?

A

Germ cell tumour

  • endodermal yolk sac
  • Immature teratoma
32
Q

What is endometriosis?

A

Endometrial tissue lying outside the uterine cavity

33
Q

What are possible locations for endometriosis?

A

Peritoneum ( pelvic side walls, pouch of Douglas, uterosacral ligament, bladder)
Ovary (endometrioma)
FT
Umbilicus, abdo scar, pleural cavity

34
Q

What is a poor consequence of endometriosis?

A

INFERTILITY (due to fibrosis and adhesion formation each month, as the endometrial tissue responds to hormonal changed)

35
Q

What is adenomyositis?

A

Endometrial tissue penetrating through into myometrium

36
Q

What are clinical features of endometriosis?

A

Severe cyclclical pelvic pain
HMB , dysmenorrhoea
dyspareunia
low back pain severe fatigue

37
Q

What are clinical exam factors suggestive of endometriosis?

A

Tenderness in pouch of Douglas
Adnexal mass
Fixed retroverted uterus
thick uterosacral ligament

38
Q

How do you dx endometriosis?

A

TVUSS
MRI
Laparoscopy

39
Q

How do you manage endometriosis ?

A

Medical

  • analgesics (NSAIDS, avoid opiates)
  • COCP (tricycle)
  • progestogens
  • GnRH agonist

Surgical

  • Excision of endometrial tissue
  • oophorectomy / FT removal / hysterectomy
40
Q

Why should you tricycle COCP

A

Better at alleviating symptoms (induces amenorrhoea)

41
Q

How long max can you give GnRH agonist, and why?

A

6 months max

risk of osteoporosis

42
Q

What is surgical tx for endometriosis?

A

Fertility sparing
- ablate/excise endometriosis

Hysterectomy, oophorectomy + immediate oestrogen only HRT

43
Q

What is chronic pelvic pain=

A

Intermittent /constant pain in lower abdo of a woman of min 6 month duration, that is NOT dysmenorrhoea or dyspareunia or due to pregnancy

44
Q

What are gynaecological causes of chronic pelvic pain?

A 
Endometriosis 
Adenomyosis 
Adhesions - chronic PID 
uterine fibroids 
ovarian cyst
45
Q

When do corpus luteal cysts occur?

A

Following ovulation

46
Q

How do you manage corpus luteal cysts?

A

Expectant (with analgesia)

They usually self resolve in 2-3 months (like all simple cysts) if they are not excessively big

47
Q

Who do theca luteal cysts occur in?

A

Pregnant women

48
Q

What is the outcome of theca luteal cysts?

A

They usually self resolve

49
Q

What is Meig Syndrome?

A

TRIAD:

  • Ovarian fibroma
  • Ascites
  • Pleural effusion
50
Q

Who does Meig Syndrome usually occur in?

A

Women over 40

51
Q

How do you manage Meig Syndrome?

A

Drain ascites and pleural effusion
THEN
Surgically remove the fibroma

52
Q

What is a thecoma?

A

A benign oestrogen secreting tumour

Presents after menopause

53
Q

What symptoms can a thecoma cause?

A

Symptoms of excess oestrogen

e.g. PMB

54
Q

What are the two theories for endometriosis?

A

Samson’s Theory - retrograde menstruation along FT and subsequent implantation on pelvic peritoneum

Meyer’s Coelomic Metaplasia Theory - De-differentiation of peritoneal cells to primitive origin, then into endometrial cells

55
Q

What are endometriosis findings on examination?

A

Thickening/nodularity of uterosacral ligaments
Tenderness in Pouch of Douglas
Adnexal mass
Fixed retroverted uterus

56
Q

What is the gold standard diagnostic method for endometriosis?

A

LAPAROSCOPY
