Q

Normal menstrual cycle

A

Days 1-4: menses

Days 5-13:

  • Follicular phase ovarian cycle: follicles develop, one follicle becomes dominant
  • Proliferative phase uterine cycle: endometrial proliferation

Day 14: ovulation

Days 15-28:

  • Luteal phase ovarian cycle: formation of corpus luteum
  • Secretory phase uterine cycle: endometrial changes to secretory lining under the influence of progesterone

Q

Hormones involved in the menstrual cycle and at which points

A

Days 5-13: rise in FSH -> development of follicles -> secretion of oestrogen

Day 14: when there is sufficient oestrogen, this causes a surge of LH to be released -> ovulation

Days 15-28: progesterone secreted by corpus luteum. if fertilisation does not occur then the corpus luteum will degenerate and progesterone levels fall. Oestrogen levels rise during this period.

Q

Management of uterine fibroids

A

Leave alone unless symptomatic, rapidly enlarging or concerned about subfertility

Q

Cervical screening programme

A

Offered every 3 years for women aged 25-49, and every 5 years to women aged 50-64

Women >65 only need a smear if they have recently had abnormal tests

73
Q

Cervical screening results interpretation

A

Inadequate: insufficient/ unsuitable sample. Repeat after 3 months. If 3 consecutive inadequate sample -> colposcopy within 6 weeks.

Negative (normal)

Borderline: abnormal nuclei but cant say for certain that it is dyskaryosis. Test HPV, if positive then colposcopy <6wks, if negative then return to normal screening programme

Mild dyskaryosis: usually cervical intraepithelial neoplasia grade 1 (CIN1) on biopsy. Test HPV, if positive colposcopy within 6 weeks, if negative return to normal screening programme.

Moderate dyskaryosis: CIN grade II. considered pre-cancerous with intermediate risk of developing into cancer. Colposcopy within 2 weeks.

Severe dyskaryosis: CIN grad III, high risk developing into cancer. Colposcopy within 2 weeks.

74
Q

What happens during colposcopy?

A

Examines the cervix to look for any abnormalities suggesting precancerous/cancerous changes.

If acetic acid is applied to the cervix, abnormal areas (such as CIN) tend to turn white (sometimes referred to as acetowhite).

If an iodine solution is applied, normal tissue (on the outside of the cervix) stains dark brown. Pre-cancerous abnormalities may not stain with iodine. The cells on the inner part of the cervix do not stain brown.

May take a biopsy to confirm the diagnosis.
Loop excision
Needle excision
Cone biopsy

75
Q

Risk factors for cervical cancer

A
HPV 16 and 18
Early age of first intercourse
High number of sexual partners
Low socioeconomic group
Smoking
Partner with prostatic or penile cancer
Premenopausal age
76
Q

Presentation and types of cervical cancer

A

90% are squamous cell carcinomas and 10% are adenocarcinomas

Presentation: may be asymptomatic.
PCB, discharge, IMB, ulcer/ mass

77
Q

Investigations for cervical cancer

A

Borderline or mild dyskaryosis at smear: HPV test -> if positive then colposcopy clinic in 6 weeks, if negative then return to normal screening programme

Moderate or severe dyskaryosis: colposcopy within 2 weeks

Colposcopy investigations: staining with acetic acid or iodine, and a biopsy (loop, needle, cone biopsy)

Following diagnosis -> MRI/CT examination to check for mets and staging

Blood tests and CXR may also be done

78
Q

Management and staging of cervical cancer

A

Staging:
0 - carcinoma in situ
1 - confined to cervix
2 - beyond the cervix
3 - spread to the pelvic side wall, or affecting ureter or lower third of vagina
4 - involves rectal or bladder mucosa, or beyond true pelvis

Management:

  • If a large loop excision has been done and the lesion has been completely removed then no further Mx is necessary
  • Surgery, chemo, radiotherapy are all options depending on patient circumstances
79
Q

Endometrial cancer risk factors

Endometrial cancer protective factors

A
Postmenopausal
Unopposed oestrogen (exogenous, obesity, PCOS, nulliparity, late menopause, tamoxifen)

Protective factors: COCP, combined HRT

80
Q

Features and presentation of endometrial cancer

A

Most are adenocarcinomas

Presentation: PMB, irregular bleeding, IMB, normal examination

81
Q

Endometrial hyperplasia

A

Premalignant condition

Simple hyperplasia and complex hyperplasia - treated with progesterone to encourage regression

Atypical hyperplasia has a high chance of developing into cancer so hysterectomy is advised

82
Q

Investigations for endometrial cancer

A

Gold standard: hysteroscopy and biopsy
Pelvic USS (measure endometrial thickness)
Endometrial sampling (pipelle biopsy)
MRI/CT for staging

Post menopausal women should have an endometrial thickness of <5mm due to their low oestrogen levels, endometrial cancer causes increased oestrogen which thickens the endometrium

83
Q

Staging and prognosis of endometrial cancer

A

Stage 1: body of the uterus (85% 5yr)
Stage 2: extends to cervix (60% 5yr)
Stage 3: adnexae, or +ve peritoneal cytology (40% 5yr)
Stage 4: involves bladder or bowel mucosa (10% 5yr)

84
Q

Management of endometrial cancer

A

Total abdominal hysterectomy and bilateral salpingo-oophorectomy = mainstay of treatment

Stage 3 requires surgical debulking before radiotherapy
Stage 4 requires a mixture of surgery, radiation and palliation

85
Q

Risk factors for ovarian cancer

Protective factors for ovarian cancer

A
Age (60-64 peak incidence)
FHx
BRCA 1/2
Lynch II syndrome
Nulliparity
Early menache and late menopause
Smoking
Obesity

Protective: pregnancy, breast feeding, exercise (due to less ovulation)

86
Q

Features and presentation of ovarian cancer

A

Epithelial, germ cell, sex-cord stromal, secondary malignant

Presentation: often a silent killer. Abdo distension, bloating, abdo pain, abdo mass, urinary frequency, PMB, loss of appetite

87
Q

Investigations for ovarian cancer

A

Pelvic USS
CA125 tumour marker
CT abdo pelvis (+/- chest)

Suspected patients under 40 should have AFP, b-hCG and CA125 levels

88
Q

Staging and prognosis for ovarian cancer

A

Stage 1: localised to ovary/ovaries (80% 5yr)
Stage 2: peritoneal deposits in pelvis (60% 5yr)
Stage 3: peritoneal deposits outside of pelvis (25% 5yr)
Stage 4: distant mets (5-10% 5yr)

89
Q

Management of ovarian cancer

A

Surgery: total abdominal hysterectomy and bilateral salpingo-oophorectomy and omentectomy (plus peritoneal washings)

Chemotherapy may be required post-op in stage 2 and 3

Surgery is usually for palliation in stage 4

90

A

1: partial/total removal of clitoris and/or prepuce
2: partial/total removal of clitoris and labia minora +/- excision of labia majora
3: narrowing of vaginal orifice with creation of a covering seal (apositioning of labia)
4: all other harmful procedures for non-medical reasons

95
Q

Cervical ectropion

  • what is it
  • presentation
  • investigations
  • management
A

High oestrogen causes the stratified squamous epithelium of the ectocervix to undergo metaplastic change into columnar epithelium with releases mucus

Presentation: asymptomatic, discharge, IMB, PCB

Ix: clinical diagnosis, pregnancy test, triple swabs, cervical smear

Mx: leave alone if asymptomatic, stop oestrogen medications, ablation (cryotherapy, or electrocautery)

96
Q

Cervical polyps

  • what are they
  • presentaiton
  • ix
  • mx
A

Benign growths protruding form inner surface of cervix

Asymptomatic, abnormal vaginal bleeding (menorrhagia, IMB, PCB, PMB), vaginal discahrge

Histological exam after removal, triple swabs, cervical smear

Mx:
Small polyps -> grab and twist with forceps -> falls off
Large polyps -> remove with diathermy

Send polyps for histology
