Q

ASC-US- management

A
Repeat cytology (1 yr):
-if ASC- colposcopy
HPV testing:
-if HPV positive- colposcopy
-if HPV neg- repeat cotesting in 3 yrs

Q

LSIL- management

A

LSIL w/ neg HPV test:
-repeat cotesting (1 yr)- if ASC or HPV + test- colposcopy
LSIL w/ no HPV test: colposcopy
LSIL with + HPV test: colposcopy

17
Q

HSIL- management

A

-Immediate loop electrosurgical excision
OR
-colposcopy- No CIN2,3 or CIN2,3

18
Q

HPV- gold standard for dx

A

colposcopy with directed biopsy

19
Q

Colposcopy

A
  • colposcope- microscope with magnification
  • cervix is washed with 3% acetic acid- large nuclei of abnormal cells turn white (acetowhite changes)
  • must visualize entire SCJ!!
  • directed bx and ECC (endocervical curettage)
20
Q

colposcopy- look for?

A
  • acetowhite changes
  • punctuations (red dots)
  • mosaicism
  • abnormal vessels
  • masses
21
Q

LSIL with + HPV test- do what?

A

colposcopy!!

22
Q

treatment

A
  • ablative (cant follow up- so never considered)
  • excisional:
  • cold knife cone- if EEC +
  • LEEP (loop electrode excisional procedure)- if EEC negative
23
Q

excisional tx- done when?

A
  • ECC + (needs cold knife cone)
  • unsatisfactory colposcopy (no SCJ)
  • discrepancy b/w pap and bx
24
Q

risks of excisional procedures

A
  • cervical incompetency- 2nd trimester pregnancy loss
  • PPROM (preterm premature rupture of membranes)
  • cervical stenosis
  • bleeding, infection- operative risks
25
Q

Cervical carcinoma

A
  • precursor lesions precede invasive carcinoma by 10 yrs
  • 91% caused by HPV
  • SCC- 80%
  • adenocarcinoma/adenosquamous- 15%
  • spread by direct invasion and lymphatics
  • staged clinically
26
Q

Cervical carcinoma- sx’s

A
  • watery vaginal bleeding
  • postcoital bleeding (after sex)
  • intermittent spotting
27
Q

Cervical carcinoma- management- microinvasive

A

-cold knife cone or hysterectomy

28
Q

Cervical carcinoma- management- invasive (stage 1A2)

A

-radical hysterectomy with LN dissection

29
Q

Cervical carcinoma- management- bulky dz (1b and 2a)

A

-radical hysterectomy with LN dissection or radiation tx and cisplatin based chemotx

30
Q

Cervical carcinoma- management- stage 2b and greater

A

-external beam radiation and concurrent cisplatin based chemotx

31
Q

prevention of cervical cancer

A
  • sexual abstinence/ limit number of partners
  • use barrier protection!!!
  • regular exams and pap smears
  • vaccination!!!
32
Q

HPV vaccine

A
  • 3 injection series- 1st dose, 2nd dose 2 months later, 3rd dose 6 months from 1st
  • or 2 dose series in < 15 yo
  • recommended vaccination for all girls and boys ages 9-26!!!!
33
Q

Gardasil

A
  • 4 strain vaccine- 6, 11, 16, 18

- 9 strain- 31, 33, 45, 52, 58

34
Q

Cervarix

A
  • against 16 and 18

- no longer available in US!!

35
Q

HPV vaccine- SE’s

A
  • dizziness
  • HA
  • injection site rxns
