Q

Cancer antigen-125 (CA-125) should be screened if a patient is suspected of having ovarian cancer. What cut off would trigger the need to perform an abdominal ultrasound in a patient according to NICE guidelines?

2 - >35 IU/mL
3 - >350 IU/mL
4 - >3500 IU/mL

Q

Cancer antigen-125 (CA-125) should be screened if a patient is suspected of having ovarian cancer. However, CA-125 has been showed be raised in all of the following, EXCEPT which one?

1 - endometriosis

1 - transvaginal ultrasound
2 - abdominal MRI
3 - abdominal CT

A

1 - transvaginal ultrasound

CT only if CA-125 is high and ultrasound suggest ovarian cancer

Bimanual examination can be effective at identifying a mass

21
Q

Why is it difficult to identify the prevalence of ovarian cysts?

A
  • most women don’t have any symptoms so don’t know they have them
  • normally a random finding in an examination
22
Q

In the follicular development of the menstrual cycle, which hormone is key for the development of follicles?

1 - LH
2 - FSH
3 - testosterone
4 - oestrogen

A

2 - FSH
- also drives the formation of the dominant follicle

23
Q

Which hormone is key for driving ovulation?

1 - LH
2 - FSH
3 - testosterone
4 - oestrogen

A

1 - LH

24
Q

There are functional and non-functional cysts. There are 3 types of functional cysts, what are they?

3 - chocolate, corpus luteum, theca letein
4 - follicular, corpus luteum, PCOS

A

1 - follicular, corpus luteum, theca letein

25
Q

Follicular cysts can grow and become >2.5cm in diameter. These follicular cysts contain granulosa cells. What do granulosa cells secrete which is able to decrease the frequency of menstruation (normal vaginal bleeding)?

A
  • estrogen
  • excess estrogen produced by follicular cells leads to decreased frequency of menstruation
  • decreased frequency of menstruation = increased risk of follicular cysts
26
Q

If pregnancy doesn’t occur, what is the general life span of the corpus luteum?

1 - 5 days
2 - 10 days
3 - 14 days
4 - 21 days

A

3 - 14 days

27
Q

1 - 4 weeks
2 - 8 weeks
3 - 12 weeks
4 - 14 weeks

A

4 - 14 weeks

28
Q

In the management of ovarian cysts a woman needs to be confirmed as non pregnant, what 2 tests could be performed?

1 - ultrasound and serum hCG
2 - ultrasound and urine pregnancy test
3 - urine pregnancy test and hCG
4 - urine pregnancy test and ultrasound

A

3 - urine pregnancy test and blood hCG

29
Q

51 year old lady is referred to the assessment unit by her primary care team. She has:

  • 2/52 history of breathlessness on exertion
  • several months of pelvic pain and increasing abdominal girth despite decreased appetite and poor oral intake
  • she looks unwell, her abdomen is tense and distended and you think she has ascites
  • SOB on exertion and bilateral pleural effusions

3 - CT TAP
4 - MRI

A

3 - CT TAP

TAP = thoracic, abdominal and pelvic

Results confirm an ovarian mass, large volume ascites, numerous omental (fat above abdominal organs) metastases and bilateral pleural effusions

31
Q

51 year old lady is referred to the assessment unit by her primary care team. She has:

  • 2/52 history of breathlessness on exertion
  • several months of pelvic pain and increasing abdominal girth despite decreased appetite and poor oral intake
  • she looks unwell, her abdomen is tense and distended and you think she has ascites
  • SOB on exertion and bilateral pleural effusions
  • raised CA125
  • ovarian mass, large volume ascites, numerous omental (fat above abdominal organs) metastases on CT

How can we identify the primary tumour?

1 - PET-CT
2 - image guided core biopsy
3 - needle biopsy
4 - any of the above

A

2 - image guided core biopsy

This will tell us the type of cancer

In this case a high grade serous epithelial ovarian cancer is confirmed from the metastatic biopsy

This is the most common form of ovarian cancer

32
Q

This is the basic staging for FIGO

Q

51 year old lady is referred to the assessment unit by her primary care team. She has:

  • 2/52 history of breathlessness on exertion
  • several months of pelvic pain and increasing abdominal girth despite decreased appetite and poor oral intake
  • she looks unwell, her abdomen is tense and distended and you think she has ascites
  • SOB on exertion and bilateral pleural effusions
  • raised CA125
  • ovarian mass, large volume ascites, numerous omental (fat above abdominal organs) metastases on CT

Is this women suitable for complete cytoreduction (removal of all visible cancer) of all macroscopic disease?

A
  • no

She has metastatic disease

Typically the aim of ovarian cancer is surgical cytoreduction, BUT not possible here

34
Q

The same as previous slide patient would receive 3 cycles of neoadjuvant platinum based chemotherapy, with the following results:

  • CA125 has fallen to the normal range
  • End of treatment CT TAP shows an excellent response with regression of several metastases and significant reduction of size of the others.

She is now operable and proceeds to surgery. She has a total abdominal hysterectomy and bilateral salpingo-oophorectomy and all other visible disease is removed. Is this surgery palliative or radical?

A
  • radical

The aim is curative

35
Q

Patients with ovarian cancer may have genetic mutations, such as the breast cancer susceptibility gene 1 and 2 (BRCA1/2). Which of the following should these patients be offered prior to and following treatment?

1 - genetic counselling
2 - breast cancer screening (annual MRI for 30-49 and mammogram a5 40 y/o)
3 - modify risk factors (smoking, obesity, exercise)
4 - preventative breast surgery (bilateral mastectomy and salpingo-oophorectomy)
5 - all of the above

A

5 - all of the above

36
Q

If a patient has a mutation in the tumour suppressor genes BRCA1 and 2, this can lead to tumour development. Which of the following drugs can be used to inhibit tumours that are growing due to BRCA 1 and 2 mutations?

1 - Aromatase inhibitors
2 - Tamoxifen
3 - PARP inhibitors
4 - all of the above

A

3 - PARP inhibitors

PARP = Poly (ADP-ribose) polymerase
PARP is an enzyme involve din DNA and cellular repair

If you inhibit PARP then tumour cells cannot continually repair themselves and die

Typically only with in BRCA1 and 2 mutations
