A

When endometrial tissue grows outside of the uterine cavity

Q

Investigation and management for endometriosis

A

Gold - diagnostic laparoscopy
(Endometrial tissue seen on an ovary is called a ‘chocolate cyst’)

Mx- OCP - back to back, no breaks -> Mirena / depot
Surgical -> ablation and fulguration or excision
(Need to take into account fertility - pregnancy improves Sx as no ovulation)

Q

In PCOS what does the term ‘polyfollicular’ mean? Basic pathophysiology ?

A

Each month the follicle is expelled onto the surface of ovary and turns into a cyst

Ovaries are overstimulated (GnRH-LH) and produces an excess of testosterone which causes an increase in insulin levels and dyslipidaemia

36
Wilson and jugner criteria for screening
Knowledge of the disease The condition should be important. There must be a recognisable latent or early symptomatic stage. The natural course of the condition, including development from latent to declared disease, should be adequately understood. Knowledge of the test Suitable test or examination. Test acceptable to population. Case finding should be continuous (not just a 'once and for all' project). Treatment Accepted treatment for patients with recognised disease. Facilities for diagnosis and treatment available. Agreed policy concerning whom to treat as patients. Cost considerations Costs of case finding (including diagnosis and treatment of patients diagnosed) economically balanced in relation to possible expenditures on medical care as a whole.
37
What should be measured in all women under 40 with complex ovarian mass? Why?
Lactate dehydrogenase LDH Alpha-fetoprotein AFP HCG Possibility of germ cell tumours
38
Endometrial ca is oestrogen dependent. What are the risk factors and how are some of them related to this fact?
HRT (especially tibolone -> selective oestrogen receptor modulator) Obesity - peripheral conversion of adipose tissue -> oestrone Diabetes HNPCC (genetics) PCOS
39
Stages of endometrial ca ? Mx at each stage?
1 - confined to a)endometrium b)more than half of myometrium Total abdominal hysterectomy with bilateral salpingo-oophorectomy 2- involves corpus and cervical stroma Radical hysterectomy with pelvic node clearance 3- local spread beyond uterus De bulking surgery with chemo and radio - sentinel node biopsy may be taken 4- bladder / bowel mucosa

50 y/o lady presented to her GP with increased abdominal swelling. She has noticed that her tummy was getting bigger. She describes herself as getting fatigued more recently and has episodes of bloating. She also reports a change in her appearance of her breast. FH: Her mother passed away from bowel CA. SH: She smokes 20 cigarettes a day and drinks 14 units a week. Examination of her abdomen showed a smooth pelvic abdominal mass that is palpable below the umbilicus. Examination of her breast showed dimpling of the skin. No erythema around the breast was noted. DDx? Ix and why?
Ovarian cyst / cA Breast Ca Bloods - FBC, LFT, U&E, tumour markers (Ca125, CEA, AFP, b-HCG, inhibit, oestradiol) -tumour burden, baseline (in case of surgery) Imaging - transvaginal US, CT abdo / pelvis / chest -identify any abnormality in overlies an confirm if cyst is benign Breast triple assessment -genetic profiling / grading
41
Parts of the breast triple assessment
``` Examination Fine needle aspiration (cytology) Imaging -if >35 can do mammogram If <35 USS -> MRI if either are not definitive ```
42
Mx of ovarian cyst
Conservative Watch and wait if <50mm 50-70mm -> annual follow up Surgical Persistent simple cyst 5-10cm or complex cysts can have surgical removal to prevent torsion
43
What is oligomenorrhea?
Periods occur between 35days and 6 months
44
Mnemonic to remember pathological causes of amenorrhea?
``` A THOOP Adrenal Thyroid Ovary Outflow tract obstruction Pituitary ```
45
Diagnosis of PCOS needs?
2/3 of 1- polycistic ovaries on US (12 or more follicles on enlarged ovary) 2- irregular periods (over 35 days appart) 3- Hirsutism - clinical - acne or excess body hair - biochemical - raised testosterone
46
Features of PCOS
``` Subfertility Oligo/amorhorrea Hirsutism / Acne Obesity Miscarriage ```
47
PCOS ix?
``` Bloods FSH - usually normal Prolactin - exclude prolactinoma TSH Serum testosterone LH - usually raised ``` Ultrasound - pelvic / trans vaginal Screening for diabetes Check lipids

Management of PCOS ? Specific drug for facial Hirsutism
Advice diet and exercise Treat with oral contraceptive if fertility not required Hirsutism Cyproterone acetate / sprironolactone (antiandrogens) [must avoid conception on these] Metformin - insulin sensitiser - reduces insulin - reduces Hirsutism / androgens Eflorthinine (topical androgen) -for facial hirtuism

When it invades the basement membrane

Stages of Cervical Ca? What is the classification called?
FIGO classification (international federation of gynae and obs) Stage 0 - CIS Stage 1 - Ca confined to CERVIX only (a-microscopy only, 1b-visible macroscopically) Stage 2- confined to cervix and UTERUS Stage 3 - invades the PELVIC WALL And/or LOWER 1/3 of vagina And/or causes KIDNEY problems Stage 4 - ca extended beyond PELVIS And/or involves BLADDER/RECTUM
55
What is parametrium
Fibrous tissue that separate the supravaginal portion of the cervix from the bladder -> informs of cervix and extends laterally between layers of broad ligaments
56
Management of cervical ca based on stage.... 1a? Lymph node negative? Lymph node positive ?
1a - cone biopsy or simple hysterectomy LN-ve Desire fertility -> radical trachelectomy If don’t require fertiliy or already at stage 2a -> Radical abdominal hysterectomy (hysterectomy, pelvic node clearance, removal of parametrium, + upper 1/3 of vagina) LN+ve or stage 2b+ Chemoradiotherapy -> also used if older / medically unfit
57
What happens in radical trachelectomy?
80% of cervix and upper vagina removed
58
What is adenomyosis? Symptoms?Older or younger population than endometriosis? Seen O/E? Investigation for diagnosis? Mx?
Endometrial tissue disperses within myometrium Can be ASx menorrhagia, pain (constant but worse on periods) ~40yrs (older and often after children) Mildly enlarged, tender uterus MRI for diagnosis Hysterectomy -mirena / COCP for sx relief
59
What hormone reduces risk of endometrial ca?
Progesterone Unopposed oestrogen causes excessive proliferation of endometrial cells
60
Where is the most common place for recurrence of endometrial ca?
Vaginal vault usually within 3 yrs | -> radiotherapy of vaginal vault after TAHBSO surgery
61
Types of ca of ovarian epithelium? | Unique features?
Serous adeonoCa Endometrioid Mucinous Clear cell Most common type of ovarian cyst
62
2 Germ cell tumours in ovarian Ca unique feautres
Teratomas Grow hair / teeth Smal bilateral often asx Dysgerminoma Teens / young adults Particularly sensitive to radiotherapy
63
Type of stromal ovarian ca? Unique feature?
Sex cord tumours | Secrete inhibin -> used as tumour marker for recurrence
64
