The Uterus And Cervix Flashcards

1
Q

Leiomyomata

A
  • Fibroids - benign tumours of the myometrium.
  • Present in 25% of women.
  • More common near menopause, Afro-caribbeans and in those with a family history.
  • Less common in parous women and with cocp.

Q

Fibroids - in menopause and pregnancy

A
  • They are oestrogen and progesterone dependant so shrink following the menopause.
  • Variable in pregnancy - can shrink, stay the same or grow in size - difficult to predict.

Q

Fibroids - Symptoms

A
  • 50% are asymptomatic and only discovered during abdo or pelvis examination.
  • Cause menorrhagia, dysmenorrhoea, pain if torsion occurs, urinary frequency if pressure on the bladder, hydronephrosis if pressure on ureter.
  • Fertility is affected if tubal ostia are blocked or if fibroids affect implantation.

Q

Fibroids - Complications

A
  • Red degeneration - caused by inadequate blood supply - pain, uterine tenderness, haemorrhage and necrosis.
  • Hyaline or cystic degeneration can occur after the menopause.
  • 0.1% are leiomyosarcoma - malignant tumour.

Q

Fibroids - investigations

A
  • Ultrasound is helpful but MRI or laparoscopy can sometimes be required to distinguish fibroids from an ovarian mass.
  • Hysteroscopy can be used to assess distortion if fertility is an issue.
  • Hb can be low due to bleeding or high as some fibroids produce erythropoetin.

Q

Fibroids - Medical Management

A
  • Large fibroids that remain in situ should be monitored regularly for malignant change.
  • Tanexamic acid, nsaids or progesterones can be tried but often ineffective for menorrhagia.
  • GnRH agonists cause amenorrhoea and fibroid shrinkage - induce temporary menopause. Use is limited for a maximum of 6 months due to side effects e.g. loss of bone density.

Q

Fibroids - Surgical Management

A
  • Hysteroscopic - 3-4cm fibroids can be removed following pretreatment with GnRH agonist.
  • Uterine artery embolisation by radiologists - reduces fibroid volume by 50%.
  • Myomectomy if fertility to be preserved.
  • Hysterectomy if fertility not required.

Q

Adenomyosis

A
  • Presence of endometrium in the myometrium.
  • Associated with fibroids and endometriosis.
  • Sx - can be asymptomatic but usually painful, regular and heavy menstruation.
  • Ix - adenomysis can be identified on MRI.

Q

Adenomyosis - Management

A
  • IUD, cocp and nsaids can be used to control sx.
  • GnRH agonists can help but max use is 6 months due to side effects - can be used to see if a hysterectomy would be beneficial.

Q

Endometritis

A
  • Infection of the uterine cavity - can potentially spread to the pelvis if left untreated.
  • Organisms - Chlamydia, gonococcus, E Coli, Staphylococcus or clostridia.

Q

Endometritis - Causes and Features

A
  • Causes - secondary to STI, as a complication of surgery e.g. C section or TOP, due to foreign tissue e.g. IUD or malignancy.
  • Features - painful and tender uterus, pv bleeding, open cervical os and systemic upset.

Q

Endometritis - Ix and Mx

A
  • Ix - high vaginal and cervical swabs and bloods.
  • Mx - broad spectrum abx and ERPC (evacuation of retained products of conception) if required.

Q

Intrauterine Polyps

A
  • Small and usually benign tumours commonly found in women aged 40-50 years especially when oestrogen levels are high e.g. tamoxifen.
  • Sx - can cause menorrhagia or IM bleeding.
  • Ix - diagnosed on ultrasound or hysteroscopy.
  • Mx - resection with cutting diathermy or avulsion.

Q

Endometrial Carcinoma

A
  • The most common genital tract malignancy.
  • Only 15% cases in premenopausal women.
  • >90% are adenocarcinoma and the next most common is adenosquamous carcinoma.

Q

Endometrial Ca - Risk Factors

A

Principle is high ratio of oestrogen to progesterone - exogenous unapposed oestrogen, obesity (androgen converted to oestrogen), PCOS, nulliparity, late menopause, ovarian granulose cell tumour or use of Tamoxifen.

16
Q

Endometrial Ca - Features

A

Most commonly post-menopausal bleeding but also intermenstrual bleeding or recent onset menorrhagia in premenopausal women.

17
Q

Endometrial Ca - Staging

A
  1. Confined to the uterus - 1a endometrium only, 1b < half or 1c > half of myometrium.
  2. There is spread to the cervix - 2a - endocervical glands or 2b - cervical stroma.
  3. Invades through the uterus - 3a - ovaries or fallopian tube, 3b - vagina and 3c - pelvic LNs.
  4. Distant spread - 4a - to bowel or bladder and 4b - metastases further afield.
18
Q

Endometrial Ca - Ix and Mx

A
  • Ix - USS, hysteroscopy and endometrial biopsy. An MRI is performed is spread suspected.
  • Mx - Surgery - 75% present in stage 1 and undergo hysterectomy and bilateral salpingo-ooprectomy unless unfit for surgery. Radiotherapy also used in patients at high risk of lymph node involvement.
19
Q

The Cervix - Histology

A
  • The endocervix is lined with columnar epithelium and ectocervix is lined with squamous epithelium.
  • The transformation zone - when columnar epithelium is exposed to vaginal ph and undergoes metaplasia to squamous epithelium. These cells are susceptible to neoplastic change.
20
Q

Cervical Ectropion

A
  • The columnar epithelium of the endocervix is visible at the os. Common in young women especially those on the cocp.
  • Can cause discharge or PC bleeding.
  • Can be treated with cryotherapy if problamatic following exclusion of carcinoma.
21
Q

Cervicitis

A
  • Acute - caused by STIs. Ulceration and infection are sometimes found in severe prolapses.
  • Chronic - often seen with an ectropion and causes abnormal discharge. Treat with abx.
22
Q

Cervical Polyps

A
  • Benign tumours of the endocervical epithelium.
  • Common in women over 40 years.
  • Can cause IM or PC bleeding.
  • Mx - polyps can be removed without anaesthetic and examined to exclude neoplasm.
23
Q

Nabothian Follicles

A

Where squamous epithelium has formed by metaplasia over endocervical cells. The columnar cell secretions are trapped and form cysts - white swellings.

24
Q

Cervical Intraepithelial Neoplasm (CIN)

A
  • Cervical dysplasia - atypical cells within the squamous epithelium.
  • Grade 1 - atypical cells in inner third.
  • Grade 2 - atypical cells in inner two thirds.
  • Grade 3 - atypical in full thickness - this is carcinoma in situ and if abnormal cells invade basement membrane its malignancy.
25
Q

Cervical Ca - Risk Factors

A
  • Human Papilloma Virus - sexually transmitted so number of sexual contacts is a risk factor.
  • Others - cocp, smoking, immunocompromise and long term steroid use.
26
Q

CIN - Mx

A

A large loop excision of the transformation zone (LLETZ) or diathermy loop excision (DLE) is performed under local anaesthetic for grades 2 and 3.

  • Complication - higher risk of preterm labour.
27
Q

Cervical Ca

A
  • Incidence is 1 in 80,000 women in the UK. Can affect women aged between 30-80 years.
  • 90% are squamous cell carcinoma and 10% are adenocarcinomas - worse prognosis as less are detected on smear tests.
28
Q

Cervical Ca - Clinical Features

A

Can be asymptomatic, post-coital bleeding, vaginal discharge, intermenstrual or postmenopausal bleeding are common.

29
Q

Cervical Ca - Staging

A
  1. Confined to the cervix.
  2. Invasion of the vagina.
  3. Invasion of lower vagina or pelvic walls.
  4. Invasion of bladder or rectal mucosa.
30
Q

Cervical Ca - Management

A
  • Microinvasive 1a disease - cone biopsy or hysterectomy in older women.
  • Other stage 1 and 2a - radical abdominal hysterectomy or chemo/radiotherapy in older women.
  • Stage 2b and upwards - chemo/radiotherapy.
