Q

Describe colposcopy?

A

this allows the cervix to be examined in more detail through the use of a speculum and microscope
the squamocolumnar junction must be visualised
abnormal epithelium contains more protein and less glycogen than normal epithelium meaning when acetic acid is applied they appear white in colour and easily identifiable
can then take punch biopsy for histopathology

Q

Describe stages of cervical cancer?

A

1: just in cervix (although A2 and B risk of lymph nodes involvement)
2: spread to adjacent organs e.g. vagina or uterus

Q

Treatment of cervical cancer recurrences?

A

most recurrences are only suitable for palliative care

19
Q

Describe the HPV vaccine?

A

this is for age 12-13 now given to boys as well as girls, in two doses six months apart
currently using quadrivalent vaccine covering 16,18,6 and 11
offers about 70% protection
nanovalent vaccine exists but not used in Uk yet

20
Q

Most uterine malignancies arise from _____

A

the endometrium- most commonly adenocarcinoma

21
Q

What is considered to increase risk of endometrial malignancy? What does this then mean?

A

high levels of oestrogen are considered to increase risk

factors that may increase oestrogen include: PCOS, late menopause, nulliparity, obesity, unopposed oestrogen, HRT, tamoxifen, oestrogen secreting tumours
interestingly evidence of endometrial cancer is lower in women who have used the COCP

22
Q

Presentation of endometrial carcinoma?

A

AUB is principle symptom
post menopausal bleeding!
less commonly vaginal discharge
pain is rare in early disease

23
Q

Post menopausal bleeding is ____

A

malignancy until proven otherwise

24
Q

Investigations for endometrial carcinoma?

A

TV US is usually first line and in post menopausal women can measure endometrial thickness, smooth regular endometrium < 4 mm makes malignancy unlikely
endometrial biopsy
D and C
hysteroscopy allows visualisation of the uterine cavity, enabling biopsy/ curettage to be done

25
Q

Treatment of endometrial carcinoma?

A

main stay of treatment is surgical: hysterectomy and bilateral oophorectomy laparoscopically, lymphadenectomy may be advised in some cases
if there is spread beyond the uterus treatment is tailored to the individual
radiotherapy be used as an adjuvant to prevent recurrence
radiotherapy or high dose progesterones can also be used in those unsuitable for surgery
in widespread disease chemo may be considered

26
Q

Prognosis of endometrial carcinoma?

A

most have a good prognosis with no recurrence

27
Q

Risk factors for fibroids?

A

age, obesity, afro carribbean ethnicity, nulliparity

28
Q

Symptoms of fibroids?

A

heavy and/ or painful periods, abdo pain, lower back pain, urinary frequency, constipation, dyspareunia

29
Q

Treatment of fibroids?

A

symptom relief: mirena coil, tranexamic acid, NSAIDs, COCP, progesterone pill days 5-26
to shrink fibroids: GnRH analogues or ullipristal acetate
surgery to remove uterus or fibroids if very bad (myomectomy, hysterectomy and uterine artery embolisation)

30
Q

What is the peak age of ovarian cancer?

A

75- mainly occurs in the elderly

31
Q

Risk factors for ovarian cancer?

A

number of times ovulated is biggest risk factor therefore…

COCP decreases risk
Breast feeding decreases risk
nulliparity increases risk

5-10% of cases have a genetic predisposition so FH increases risk
HNPCC and BRCA1 and 2 are implicated

endometriosis may increase risk

32
Q

Presentation of ovarian cancer?

A

may be asymptomatic and often presents late as symptoms are non-specific
bloating, early satiety, abdo pain or swelling, constipation and menstrual changes
most patients complain of abdo distension which may be due to ascites or mass

33
Q

In any women with new onset IBS over 50 ______

A

must think of ovarian cancer

34
Q

What is the RMI?

A

Risk of malignancy index for ovarian cancer

= USS score x menopausal score x Ca125

35
Q

Suspicious USS findings for ovarian cancer include?

A

complex mass with solid and cystic area, multi loculated, thick septations, associated ascites, bilateral disease

36
Q

Describe some markers for ovarian cancer?

A

Ca125 is raised in 80% ovarian cancers but also raised in many other conditions so it’s better for monitoring progression as opposed to making a diagnosis

Carcino-embryonic antigen (CEA) may be raised in ovarian cancer esp in mucinous tumours

65% of germ cell tumours produce raised hCG and AFP

37
Q

Management of ovarian tumours?

A

treatment for benign tumours is excision and drainage
epithelial tumours get combo of chemo and surgery
may do conservative management if want to preserve fertility and only remove one ovary, if unfit for surgery may just do chemo
non epithelial tumours are often sensitive to chemo, often more important to preserve fertility as patients are younger

38
Q

Prognosis of ovarian cancers?

A

5 year survival is 40%

germ cell tumours have higher survival at 75%

39
Q

What is endometriosis?

A

condition where there are deposits of endometrium outside the uterine cavity
this tissue undergoes cyclical changes and will breakdown and bleed at the time of menstruation

40
Q

Presentation of endometriosis?

A 
pelvic pain
severe period pain affecting QOL 
dyspareunia 
pain on urination or defaecation during period
heavy periods 
nausea, constipation and diarrhoea 
infertility
41
Q

Investigations for endometriosis?

A

abdo US, TV US
dont need MRI unless deep endometriosis
may do diagnostic laparoscopy

42
Q

Management of endometriosis?

A

analgesics- NSAIDs, paracetamol, neuromodulators
Hormonal- COP, progesterone, GnRH analogues (not good long term), IUS Mirena
Surgery

43
Q

Explain the different types of fibroid?

A
  • Most common are intramural fibroids which lie within the myometrium
  • Subserosal fibroids are located on the serosal outer surface and extend outwards, they deform the normal contour of the uterus
  • Submucosal fibroids develop near the inner surface of the endometrium and extend into the endometrial cavity either causing a distortion of the cavity or filling the cavity if they are pedunculated
