25
how common are uterine fibroids
very common - 70%
26
what is the mechanism of bleeding due to uterine fibroids
mechanism depends on the location of the fibroid but thought due to increasing endometrial cavity surface area and inhibiting uterine contraction- more likely with submucosal fibroid that subserosal.
27
what is the name of the classification system used to classify the location of a fibroid
FIGO
28
A 44-year-old woman is investigated for heavy menstrual bleeding following failed medical management. An abdominal ultrasound scan shows a fibroid measuring four centimetres in diameter at the fundus. It is protruding into the uterine cavity and is distorting the endometrium although the majority of the fibroid is located within the wall of the uterus. What terminology is used to describe this type of fibroid? A. Endometrial B. Intramural C. Pendunculated D. Submucosal E. Subserosal
D - submucosal
29
A subserosal fibroid will project into the endometrial cavity. True or false
False - subserosal will indent into the abdominal cavity
30
A submucosal fibroid projects into the uterine cavity True or False
True
31
A pedunculated fibroid projecting into the endometrial cavity is an example of what type of fibroid A - Intramural B- Subserosal C- Submucosal
B - Submucosal
32
If a fibroid is <3cm in size and not distorting the uterine cavity what is the first line management
LNG- IUS
33
If a fibroid is <3cm in size and not distorting the uterine cavity but the patient declines IUS what would be the second line non hormonal management options
NSAIDs or TXA
34
what hormonal options are there for Rx fibroids <3cm in size not distorting uterine cavity but patient declined LNG IUS
CHC, oral progestogens
35
If a fibroid is >3cm in size, causing obstetric or fertility issues or compressive symptoms what should the GP do?
refer to secondary care and can start TXA or NSAIDs (mefanamic acid 500mg TDS) whilst awaiting specialist review
36
what are the surgical options that a specialist may consider for fibroids >3cm distorting uterine cavity
Uterine artery embolisation Myomectomy Hysterectomy (definite treatment)
37
Laura is a 46 year old female who has completed her family. She has a large intra-mural fibroid measuring 9cm which is distorting the uterine cavity. She has failed medical management. What would be the definite treatment for Laura 1. UAE 2. Myomectomy 3. GNRH angonist 4. Hysterectomy
4. Hysterectomy
38
Laura is awaiting hysterectomy for treatment of a uterine fibroid measuring 9cm. She failed medical treatment. What two medications can be used to help shrink the fibroid prior to surgery 1. GnRH Agonist 2. IUS 3. Mefanamic acid 4. Esmya
1. GnRH agonist 4. Esmya
39
Goserelin, Leuporelin and Triptorelin are examples of what class of medications
GnRH agonist
40
Describe the MOA of GnRH agonist
GnRH agonist work by mimicing the action of GnRH. They are synthetic decapeptides. GnRH agonist continuously provide GnRH causing the anterior pituitary to release FSH and LH continuously. Normally GnRH is released in a pulsatile manner. When a patient initially starts on GnRH agonist it causes a surge in LH and FSH however after a period of time the anterior pituitary becomes de-sensitised to the GnRH agonist and leads to down regulation and reduced FSH/LH and reduced gonadotrophin. induces menopause state.
41
how long can GnRH agonists be used for
6 months, or up to 1 year with add back HRT
42
what class of medication is Esmya
Esmya is a selective progesterone receptor modulator (UPA) works to block the action of progesterone . Can only be used intermittently currently due to concerns over causing liver failure.
43
Ullipristal acetate exerts its effect A - on the anterior pituitary B- directly on the hypothalamus C- on the progesterone receptors lining the endometrial cavity
c- on progesterone receptors lining the endometrial cavity
44
how does UPA decrease fibroid size
Inhibits cell proliferation and induces apoptosis
45
a daily dose of UPA will inhibit ovulation True or false
True
46
A patient undergoes uterine artery embolisation for treatment of fibroids. one week later presents to A&E with history of fever, rigours and pelvic pain. Bloods demonstrate raised WBC and CRP. TV USS shows the known uterine fibroid but nil else. What do you think is the most likely cause? A- appendicitis B- Pelvic infection secondary to UAE C- Ovarian torsion D- post-embolisation syndrome
D- post embolisation syndrome
47
what is the risk of malignant transformation of fibroids A - 0.1% B - 0.2% C - 0.5% D - 1%
B - 0.2%
48
Why can fibroids cause sub fertility
failure of implantation - structurally as fibroid might be in the way and secondly fibroid secretes transforming growth factor Beta that interferes with implantation
49
Increasing in the number of cells describe the process of A - hyperplasia B- Dysplasia C- Metaplasia
A - hyperplasia
50
Histology that demonstrates cells with an abnormal appearance is describing A - hyperplasia B- Dysplasia C- Metaplasia
B - dysplasia
51
Conversion of one type of cell to another so that the cell has changed form is describing A - hyperplasia B- Dysplasia C- Metaplasia
C- Metaplasia
52
what causes endometrial hyperplasia
unopposed oestrogen binds to the oestrogen receptors in the endometrial cells and stimulates endometrial cell growth
53
what are some risk factors for causing endometrial hyperplasia
- obesity -unopposed oestrogen -early menarche and late menopause -nulliparity - oestrogen secreting tumours (granulose cell) an ovulation a/s menopause and PCOS
54
A 47 year old female with BMI of 35 is investigated due to IMB. TV USS demonstrates a thickened endometrium but nil else. Histological biopsy shows ''crowded cells, irregular size and shape and an increase in the number of cells but the cells do not appear atypical'' What would the first line management be
lose weight and continuous oral or local progestogen ideally - LNG -IUS, follow up in 6 months with second biopsy (this is endometrial hyperplasia without atypia)
55
in endometrial hyperplasia without atypia if a patient declines LNG- IUS would you use A) cyclical progestogens B) Continuous progestogens
Continuous oral progestogens
56
which oral continuous progestogen is the best option for pre-menopausal women with endometrial hyperplasia without atypia
Norethisterone
57
which oral continuous progestogen is the best option for peri- or post menopausal women with endometrial hyperplasia without atypia
medoxyprogesterone acetate
58
In patients with endometrial hyperplasia without atypia at what point can you discharge them from secondary care
two consecutive negative endometrial biopsies
59
sue has been treated for 12 months with LNG-IUS for endometrial hyperplasia without atypia. Biopsy today after 12 months of treatment shows no regression or improvement. What would be the definite treatment now?
Hysterectomy (as hyperplasia has failed to improve after 12 months of treatment)
60
A 48-year-old woman Para 2+0 undergoes a hysteroscopy and biopsy for persistent intermenstrual bleeding over the past 6 months. She has a BMI of 35 kg/m2 and takes metformin for type 2 Diabetes Mellitus. She is currently not in a relationship and has completed her family. The histology report is suggestive of endometrial hyperplasia with atypia. Which of the following is most likely to represent the best management option? A. Continuousoralprogestogens for 6months B. Cyclical oral progestogens for 12 months C. Endometrial ablation D. Insertion of LNG-IUS E. Total hysterectomy
E - total abdominal hysterectomy as she has atypia
61
a patient had hyperplasia with atypia and so has been recommended TAH + BSO. They are reluctant as want to avoid surgery and ask about endometrial ablation. Why do we avoid endometrial ablation in the management of endometrial hyperplasia with atypia
risk that not all is removed and also causes intrauterine adhesions making further histological surveillance very difficult
62
what medication used in treatment of breast cancer can increase risk of endometrial hyperplasia A - Tamoxifen B - aromatase inhibitors
A - tamoxifen
63
what percentage of women with endometrial hyperplasia with atypica will have underlying malignancy A - 25% B - 46% C - 35% D- 70%
B - 46%

in a women diagnosed with endometrial hyperplasia with atypia but wanting persevere fertility how would you manage
oral high dose continuous progestogens e.g 100mg MPA or LNG -IUS and review in 3/12 with histological biopsy
