Q

What is post-menopausal bleeding?

A

Vaginal bleeding occurring after 12 months of amenorrhoea in a woman of menopausal age or who has experienced the menopause – this affects 4-11% of postmenopausal women and accounts for 5% of all gynaecology outpatient referrals

Q

How does endometrial cancer tend to present symptomatically?

A
  • Post-menopausal bleeding - profuse and persistent
  • Pre-/perimenopausal - intermenstral bleeding/menorrhagia
  • Pyometra
  • Advanced disease - pelvic pain/mass, leg swelling, haematura, PR bleeding, weight loss, fatigue, symptoms of mets

Q

What would be your differential diagnosis for someone presenting with post-menopausal bleeding?

Study These Flashcards
A
  • Trauma
  • Ovarian tumour
  • Endometrial causes - Endometrial atrophy, Endometritis/PID, endometrial polyps, endometrial hyperplasia, endometrial cancer
  • Cervical causes - cervicitis, cervical polyps, cervical cancer
  • Vulval causes - dermatitis, vulval dystrophy, cancer
  • Bleeding disorder
  • Metasatic cancer
  • GU/PR bleeding - rectal carcinoma, bladder cancer etc.
18
Q

What is post-menopausal bleeding thought of as being due to until proven otherwise?

Study These Flashcards
A

Endometrial cancer

19
Q

What investigations would you consider for suspected endometrial cancer (to diagnose it)?

Study These Flashcards
A
  • Imaging - TVUSS
  • Other - Endometrial biopsy/curettage, hysteroscopy and biopsy
20
Q

What investigations would you consider doing to stage endometrial cancer?

Study These Flashcards
A
  • Bedside - ECG
  • Bloods - FBC, U+E’s, LFTs, group and save
  • Imaging - Consider MRI/CT abdo pelvis/PET scan
  • Other - Surgical staging
21
Q

What endometrial thickness on TVUSS would raise suspicion of endometrial cancer?

22
Q

What might histopathology of an endometrial cancer show?

Study These Flashcards
A

Adenocarcinoma

23
Q

What is regarded as the gold standard for staging of endometrail cancer?

Study These Flashcards
A

Surgical staging

24
Q

How is endometrial cancer graded?

Study These Flashcards
A

FIGO grading system - based on pathological aggressiveness of disease

25
What does G1 grading of endometrail cancer indicate?
5% or less of a non-squamous or non-morular solid growth pattern (good)
26
What does G2 staging of endometrial cancer indicate?
6-50% of a non-squamous or non-morular solid growth pattern (OK)
27
What does G3 staging of endometrial cancer indicate?
\>50% of a non-squamous or non-morular solid growth pattern (bad)
28
What does stage I endomtrial cancer mean?
Cancer limited to body of the uterus only
29
What does stage II endometrial cancer mean?
Limited to body of uterus and cervix
30
What does Stage III endometrial cancer mean?
Extenstion to uterine serosa, peritoneal cavity +/- lymph nodes
31
What does stage IV endometrial cancer mean?
Extension to adjacent organs or beyond true pelvis
32
How would you manage stage I endometrial cancer?
Total abdominal hysterectomy and bilateral salpingo-oophrectomy
33
How would you manage stage II endometrial cancer?
Exploratory laparotomy and surgical staging with: * **Radical hysterectomy,** * **Bilateral pelvic lymph node dissection (BPND) +/- para-aortic lymph node clearance** * **Pelvic and peritoneal washings for cytology** * **Omental sampling if indicated**
34
How would you manage stage III/IV endometrial cancer?
* **Exploratory laparotomy with maximal tumour debulking and full surgical staging** * **Consider chemotherapy** * **Consider radiotherapy** * **Progesterone**
35
How effective is chemotherapy in endometrial cancer?
Not very effective
36
What are the main chemotherapeutic medications usedd when treating endometrial cancer?
* **Doxorubicin** * **Paclitaxel** * **Carboplatin/cisplatin**
37
What hormonal therapy is used for palliation of symptoms?
High-dose progesterone
38
When is radiotherapy used in endometrial cancer?
Following surgery
39
How does radiotherapy help in endometrial cancer?
Adjuvant radiotherapy reduces the risk of local pelvic recurrence, but confers no survival advantages to women with disease severity less than stage Ib grade 3
40
What is the prognosis of stage IV endometrial cancer?
25%
41
What are complications of endometrial cancer treatment?
* **Vaginal stenosis/atrophy/fibrosis** - following radiotherapy * **Bladder instability** - following surgery * **Sexual dysfunction** - following treatment * **Local/distant spread** * **Lymphoedema** * **Toxicity** - associated with chemo * **Bowel or bladder fistulae** - following radiotherapy
