Gynaecology: Bleeding Disorders and Cancer Flashcards
(124 cards)
1
Q
Define Post-Menopausal Bleeding?
A
Vaginal bleeding occurring at least 12 months after the last menstrual period.
2
Q
What is PMB presumed to be until proven otherwise?
A
Endometrial Carcinoma.
3
Q
Apart from Endometrial Carcinoma, what are some alternative diagnoses for PMB?
A
- Endometrial hyperplasia (with or without Atypia or Polyps)
- Cervical Carcinoma
- Ovarian Carcinoma
- Atrophic Vaginitis (diagnosis of exclusion)
- Cervicitis
- Cervical polyps
- Foreign bodies e.g. Pessaries
4
Q
What initial investigations should be performed for a woman presenting with PMB?
A
- Bimanual examination
- Speculum examination
- Cervical smear (if not already performed through national screening programme)
- Transvaginal USS
5
Q
What does TVS show?
A
- Endometrial thickness
- Pelvic pathology e.g. fibroids, ovarian cysts
- Fluid in the endometrial cavity (indicates increased risk of malignancy)
6
Q
When should a patient with PMB go in for an endometrial biopsy and hysteroscopy?
A
If…
- Endometrial thickness >4/5mm (depends on the literature) OR
- Multiple episodes of PMB
7
Q
What management options tend to follow a presentation of PMB?
A
Generally it’ll be either cancer or atrophic vaginitis…
- Cancer: surgical management options, chemotherapy
- AV: Oestrogen cream
8
Q
What is the most important thing to check when a patient presents reporting PMB?
A
Is the bleeding actually coming from the vagina, rather than the urethra or rectum
9
Q
What are the first and second line treatment options for heavy menstrual bleeding?
A
- Tranexamic acid, PO
- Merina coil
10
Q
Why is post menopausal bleeding such a concern?
A
PM women do not menstruate, therefore any bleeding noticed is pathological.
11
Q
What questions are important to ask in a PMB history?
A
- Spotting vs Bleeding vs Flooding
- Any concurrent bladder or bowel problems
- Symptoms of cancer
- RFs for cancer
- Cervical smear history
- HPV vaccine history
- Sexually active/protection
12
Q
What are the most common risk factors for endometrial cancer?
A
Non-oestrogen related:
- Smoking
- HTN
- Diabetes
Oestrogen related:
- Obesity
- PCOS Leads to many follicles, leads to high oestrogen levels)
- Tamoxifen (stimulates endometrial hyperplasia)
- Lynch syndrome (genetic mutation which increases risk of bowel and endometrial cancer)
Prolonged Oestrogen exposure:
- Nulliparity
- Early menarche
- Late menopause
13
Q
What are some causes of PMB?
A
Vaginal:
- Atrophic vaginitis
- Vulvar cancer
- Lichen sclerosis
Cervical:
- Polyps
- Ectropion
- Cancer
Uterus:
- EM cancer
- EM Hyperplasia
- EM polyp
14
Q
How would you investigate a women with PMB?
A
Visualise the vagina and cervix with an external exam + speculum.
Examine the uterus with a TVUSS within 2 weeks (urgent pathway).
15
Q
What is an Ectropion?
A
- Condition in which the glandular cells of the inner cervix begin to develop outside of the cervix, which should be squamous cells
- Symptoms: clear vaginal discharge, PCB, IMB
- Area looks red and irritated, can be indistinguishable from cancer so should be investigated
- Causes include: random congenital, hormone related (common in puberty), pregnancy, while on oral contraceptives
16
Q
What are you looking at in the TVUSS of a woman with PMB?
A
Endometrial thickness, if greater than 4mm (5 in some hospitals), need hysteroscopy and pipelle biopsy
17
Q
What would a pipelle biopsy show and how are each managed?
A
EM Hyperplasia w/o Atypia:
- Treat with progesterone
EM Hyperplasia w/ Atypia:
- Hysterectomy (possibly TAH BSO)
EM adenocarcinoma:
- Requires CT CAP for staging
- Staged using FIGO system
- If advanced refer to TAH BSO
- +/- Removal of lymph nodes depending on metastasis
+/- Radiotherapy +/- Chemotherapy (mostly paliative)
18
Q
What is a TAH BSO?
A
Total abdominal hysterectomy with bilateral salpingo-oophorectomy.
19
Q
What is the benefit of TAH BSO over just a hysterectomy?
A
- Prevents future ovarian cancer + need for intervention
- Prevents development of malignant disease (impossible to tell that early whether or not there are mets in the ovaries).
20
Q
What are your differentials for Post-Coital Bleeding?
A
- Infection
- Cancer
- Cervical Ectropion
- Cervical or Endometrial Polyps
- Vaginal atrophic changes
- Sexual abuse or trauma
21
Q
What are your differentials for Inter-Menstrual Bleeding?
A
Don’t forget…
- Think of PREGNANCY causes e.g. Ectopic, Gestational Trophoblastic Disease
- Physiological causes (Ovulation, Peri-menopause)
- Medications e.g. SSRIs, anti-coagulants, Tamoxifen, missed COCP
Vaginal causes:
- Adenosis
- Vaginitis
Cervical causes:
- STIs
- Polyps
- Ectropion
Uterine causes:
- Fibroids
- Polyps
- Adenomyosis
- Endometritis
In all cases CANCER
22

A
Endometriosis.
23
Q
What are the most common causes of Chronic Pelvic Pain?
A
- PID
- Endometriosis
- Ovarian cyst
24
Q
What are the differential diagnoses for Heavy Menstrual Bleeding?
A
Use the Mnemonic; PALM-NOICE
PALM = structural factors:
- Polyps (endometrial or cervical)
- Adenomyosis (look for bulky uterus)
- Leiomyoma (aka Fibroid)
- Malignancy (or hyperplasia)
NOICE = non-structural factors:
- Not classified
- Ovulatory dysfunction (PCOS or Hypothyroidism)
- Iatrogenic
- Coagulopathy
- Endometrial
25
How is HMB typically managed?
First line:
- Tranexamic acid (esp. if still trying to conceive!), which can cut down bleeding by up to 60%
- Mirena coil.
Alternatively:
- Other hormonal options (POP, implant, Depo, COCP)
- Surgical managements (discussed later)
- GnRH analogues can be used to manage fibroids conservatively
26
What coagulopathy is most commonly associated with HMB? What history features do you look for?
Von Willebrand's disease. Look for:
- Heavy bleeding since menarche
- Excessive surgical or dental bleeding
- Bleeding gums
- Easy bruising
- PPH
- Family history
Other coagulopathies linked to HMB include platelet disorders, leukaemia, thrombocytopenia
27
How is VWD diagnosed?
Von Willebrand antigen, might also look for factor 8 activity
28
What is considered a normal cycle?
- Length of 24-32 days
- Regularity (although this drops with age)
- N.B: if cycle flits between the normal range e.g. one month is 25 days another is 30, this is still considered regular
- Menstrual blood loss 37-43ml/cycle and mostly in first 48 hours
- However 10% of women lose more than 80ml, 3/4 of whom are anaemic
29
What factors affect degree of MBL?
- Age, highest in 40s-50s decade
- Genetics
- Parity, more children heavier periods (possibly due to adenomyosis)
30
What is the difference between menorrhagia and metrorrhagia?
Menorrhagia = HMB
Metrorrhagia = Heavy irregular bleeding
31
What is Dysfunctional Uterine Bleeding?
Heavy menstrual bleeding with no recognisable pelvic pathology, pregnancy or general bleeding disorders
aka Primary Menorrhagia
32
How do you clinically assess how heavy someone's periods are?
Difficult, can't strictly rely on subjective reporting of heaviness (50% of menorrhagia have normal loss).
Best judge is based on:
- Impact on QoL: staying off work, impact on social life, bleeding through clothing, soiling bed, disrupted sleep
- Anaemia!!!
33
When is a patient with HMB high vs low risk?
Low risk =
- Below 45
- No IMB
- No risk factors for endometrial cancer (e.g. HTN, diabetes, PCOS, fam history, obesity)
High risk =
- Above 45
- Or IMB
- Or risk factors for Endometrial cancer
- Or Suspected pathology
34
How do the assessment pathways differ between low and high risk HMB patients?
Low risk are deemed to probably not have any serious underlying pathology, therefore only go for:
- History
- Examination
- FBC
- First line treatment
- Follow up
High risk patients could well have something sinister, therefore also get:
- Pelvic USS
- Possibly Hysteroscopy and Biopsy
- THEN get first line treatment
35
What are the surgical management options for HMB?
Used for specific conditions e.g.
- Polyps= Hysteroscopic removal of polyps (MYOSURE system)
- Fibroids = Myomectomy or Uterine Artery Ablation
- Endometrial Ablation (NOVASURE- only if family complete!!!)
Can also do a Hysterectomy (definitive management)
36
How can fibroids/fibroid based HMB be managed?
Medically = GnRH analogues (good but tends to only be temporary)
Surgically = Myomectomy or Uterine Artery Embolization
37
What is the emergency management of HMB?
HMB can be managed in the short term using:
- Norethisterone 5mg PO TDS, up to 7 days
- GnRH analogues can be given monthly as injections to induce temporary medical menopause
- GnRH analogues are good for stopping heavy periods while anaemia is corrected in preparation for another, more surgical intervention e.g. in fibroids.
38
Define Oligomenorrhoea?
Infrequent periods. Cycle greater than 35 days in length but still under 6 months in length
39
Define Amenorrhoea and what are the two types?
Primary:
- No menarche by age 16
Secondary:
- Absent periods for at least 3 months if cycles previously regular
- Absent periods for at least 6 months if previously oligomenorrhoea
40
What are the main causes of Oligomenorrhoea?
- Constitutional
| - Anovulation (so PCOS, Thyroid disease, Prolactinoma, CAH)
41
What are the physiological causes of amenorrhoea?
- Prepubertal
- Pregnancy
- Menopause
42
What is Cryptomenorrhoea?
- Menses ae occurring but without external blood flow (e.g. due to imperforate hymen, absent vagina)
- Haematocolpos (blood build up in vagina)
- Haematometra (blood build up in uterus)
43
What are some pathological causes of PRIMARY amenorrhoea?
- Delayed puberty
- Imperforate hymen
- Absent vagina
- Mullerian agenesis
- Turner's
- PCOS
- CAH
44
What are some pathological causes of SECONDARY amenorrhoea?
- Pregnancy
- PCOS
- Premature menopause
- Prolactinoma
- Thyroid disease
- Cushing's
- Eating disorder
- Exercise induced
- Asherman's
- Sheehan syndrome
45
How do you distinguish primary and secondary amenorrhoea?
Primary = never had a period
Secondary = No periods in 6 months or 3 cycles
46
What is Sheehan's syndrome?
- Massive PPH
- Hypovolaemia
- Under-perfusion of the pituitary
- Becomes non functional
47
How can you distinguish between infrequent/absent periods caused by the Hypothalamus/Pituitary vs Ovaries vs Uterus
Blood test for FSH and Oestrogen:
- Hypo or Pit causes have low both
- Ovarian causes have high FSH but low oestrogen
- Uterine causes will have normal bloods
48
How would you investigate a patient with PRIMARY amenorrhoea?
- History and exam
- Check for normal pubertal developments
- Pregnancy test +/- b-hCG
- TSH
- Prolactin
- LH, FSH
- Pelvic USS if FSH normal
49
What are the differentials in a patient with primary amenorrhoea with LOW FSH?
Caused by lack of stimulation from pituitary:
- Constitutional delay
- Eating disorder
- Exercise induced amenorrhoea
- Stress induced (common in famine or war victims)
- Chronic illness
50
What are the differentials in a patient with primary amenorrhoea with HIGH FSH?
If test high FSH, pituitary is working but ovaries are not responding, have to send for karyotyping
- 46XX = primary ovarian failure (or premature menopause)
- 46XO = Turner's syndrome
51
What is the next step in the investigation of a patient with primary amenorrhoea with NORMAL FSH?
Require a Pelvic USS, check for presence of uterus.
If present, it's either:
- imperforate hymen
- vaginal agenesis
- transverse septum
If absent, send for karyotyping, it's either:
- 46 XX = Mullerian agenesis
- 46 XY = Androgen insensitivity
52
What are the three important tests for primary amenorrhoea and what do they most commonly indicate?
FSH:
- Low = Pituitary dysfunction (constitutional delay, eating disorder)
- High = Ovarian dysfunction (Primary ovarian failure, Turner's)
- Normal = something else
Pelvic USS:
- Absent uterus = Genetic conditions = Mullerian agenesis, androgen insensitivity
- Present uterus = imperforate hymen, vaginal agenesis
Karyotyping exists to identify the genetic conditions which can cause amenorrhoea (if necessary) e.g. Turner's. Mullerian...
53
How do you investigate a patient with amenorrhoea?
- History and exam
- Pregnancy
- TSH
- Prolactin
- FSH (more diagnostic)
- Pelvic USS (if FSH normal)
54
How would you interpret FSH results in a patient with secondary amenorrhoea?
If low = Pituitary = eating disorder, exercise or stress induced, chronic illness, Sheehan syndrome.
If high = Ovarian = premature ovarian failure, Turner mosaic
If normal = PCOS/Uterine so need Pelvic USS or Hysteroscopy. Most likely uterine cause is adhesions.
55
What is PCOS?
- Heterogenous endocrine disorder with unknown aetiology (link to diabetes)
- Clusters in families and accounts for 90% of amenorrhoea cases.
- Usually emerges in adolescence
56
What are the features of PCOS?
Hyperandrogenism:
- Acne
- Hirsutism (hair growth)

Also commonly get psych issues e.g. depression
57
What conditions can present similarly to PCOS?
- Hypothyroidism
- Hyperprolactinaemia
- Cushing's disease
Less closely:
- Simple obesity
- CAH
- Androgen secreting tumour
- Primary ovarian failure
58
How do you diagnose PCOS?
Rotterdam Criteria- Need 2/3 of...
- Oligomenorrhoea or anovulation
- Clinical and/or biochemical signs of hyperandrogenism (acne, hirsutism, obesity)
- Polycystic ovaries on imaging (12 follicles or more)
59
What blood tests should be ordered in potential PCOS cases?
To rule out differentials:
- TSH (Hypothyroidism)
- Serum prolactin (Hyperprolactinaemia)
Classic PCOS picture =
- Raised testosterone
- Raised LH
- Normal FSH
- Low Progesterone
- Low Sex Hormone Binding Globulin (SHBG)
Use Test and SHBG to calculate free androgen index (FAI), raised = classic of PCOS
60
What are the management options for PCOS?
Conservative:
- Weight loss is the primary intervention for PCOS! (especially good if trying to get pregnant)
- Encourage generally healthy lifestyle
- Offer screening for impaired glucose tolerance (diabetic link)
- Ask about mental wellbeing and refer appropriately
Specific management depends on what woman wants
61

COCP or Cyclical Progestogens
62
What specific intervention would you offer a woman with PCOS who wants to conceive?

- Folic acid
- Fertility assessment + partner's semen
- Refer to fertility services
- May require ovulation induction
63
What specific intervention would you offer a woman with PCOS who wants to manage their acne?
Acne:
- COCP is good for this as well, will cause periods to return
- If not should go under dermatology care for retinoids, antibiotics (nice)
Hirsutism:
- Waxing
- Laser treatment
64
What are the long term implications of PCOS?
- Higher risk of type 2 diabetes

66
How does PCOS present (menstruation wise)?
Fluctuation between HMB and Amenorrhoea
67
What is the most important contraindication of Tranexamic acid?
DVTs and PEs, as its a pro-clotting agent
68
What are the 5 common interventions for HMB?
1) Tranexamic Acid (for bleeding) +/- Mefenamic Acid (for pain)
2) Hormonal therapy: Mirena, COCP, POP, Depo...

5) If all else fails, Hysterectomy
69
How do you take Tranexamic acid?
When the bleeding occurs, 1g, 3 times a day.
70
What is crucial to check before sending a patient in for endometrial ablation?
- Is there family complete, EA can be sterilising
- Pregnancy is absolutely contraindicated following
- Must have taken an endometrial biopsy, can't miss cancer.
71
What is the classic Endometriosis presentation and what is the diagnostic gold standard?
CYCLICAL pain + pain on pooing, intercourse + irregular menstruation
72
What are the main management options for Endometriosis?
Medical:

- Mirena, COCP, POP...
(a good option is COCP trycycling, where they take it for 90 days straight)
Surgical:
- Diathermy
- Resection
- Hysterectomy
73
What is essential to test before performing a hysterectomy for endometriosis?
GnRH analogue test. Puts patients into a pseudo menopausal state which should cure their pain. IF it doesn't something else is going on and it would be worthwhile to address that before removing the uterus.
74
What are the most common gynae cancers in the UK?
Uterus and Ovarian and Cervical.
Vulval and Vaginal less common.

- Ca125
- Abdominal or Pelvic USS
103
What women are at greatest risk of cervical cancer?
Bimodal age distribution:
- 30s
- 80s
More common in women of lower SES due to reduced uptake of screening programmes.
104
What are the RFs and PFs of cervical cancer?
RFs:
- Young age at first intercourse
- Multiple partners
- No barrier contraception
- Smoking
- Long term COCP use
- Immunosuppression
Only recognised PFs are vaccination and compliance to screening programmes
105
What are the high risk (oncogenic) HPV types?
16 and 18 are the two the vaccine works against, others are rarer e.g. 31, 33, 34, 35...
Produce proteins E6 and E7 which suppresses the p53 tumour suppressor gene.
106
How common is HPV infection?
Most women will be infected at some point in their life, commonest in teens and early 20s, infection lasts about 8 months.
Cervical cancer should be viewed as a rare complication of a common infection.
107
What is CIN?
When HPV is not cleared by the body, persists, it causes...
Cervical Intraepithelial Neoplasia, an asymptomatic pre-malignant condition affecting the Transformation Zone. 60% CN1 regresses spontaneously, 30% CN3 progresses to invasive cancer over the next 5-10 years.
108
How is CIN classified?
Based on degree of infiltration of basement membrane: CN1, CN2, CN3.
Histological diagnosis.
109

1 = Confined to cervix
2 = Beyond cervix but not pelvic side wall or lower third of vagina
3 = Pelvic spread, reaches side wall or lower third of vagina
4 = Distant spread or invades adjacent organs
111
How is Cervical cancer managed?
Depends on stage:
- Micro-invasive carcinoma can be managed conservatively, cone biopsy if concerns about fertility. If family complete, hysterectomy is appropriate
- Stages 1b-2a: Wertheim's radical hysterectomy OR chemoradiotherapy
- Beyond stage 2a: Chemoradiotherapy
- Post-Op Radiotherapy can be offered
Ideally patients only have one of surgery or CR, both has too many side effects.

- 3 yearly between 25 and 50
- 5 yearly between 50 and 65
- After 65 only selected patients
116
How are the results from a cervical smear interpreted?
Normal = Routine recall
Moderate or Severe Dyskaryosis = Colposcopy + Histology

VIN (premalignant condition) can present as:
- Asymptomatic
- Itching, burning, pain
- Same as CIN mostly resolved but can progress to cancer
121
