Cervical & Uterine Disease Flashcards
screening for cervical disease age 21-29
cytology alone q 3 years
no HPV testing
screening for cervical disease age 30-65
HPV & cytology q 5 years
indications for yearly screening for cervical disease (4)
immunocompromised
CIN 2/3
hx cervical CA
HIV +
HIV+ cervical disease screenings
cytology 2x in the year after diagnosis
annually thereafter
what cytology finding is consistent w/ CIN 1
low-grade squamous intraepithelial lesion (LSIL)
LSIL + HPV –>
LSIL w/o HPV –>
colposcopy
repeat cotesting at 1 year
cytology finding consistent w/ CIN 2/3
high-grade squamous intraepithelial lesion (HSIL)
CIN 1
lower 1/3 of epithelium
lesions typically regress in 12 mo
CIN 2
lower 2/3 of epithelium
about 50% regress
22% progress to CIN 3
few increase to invasive cancer
CIN 3
involves > 2/3 of the epithelial thickness
up to 40% progress to invasive cancer
goal of colposcopy
& if not achieved?
complete visualization of the transformation zone
incomplete visualization –> endocervical curettage
high risk & low risk HPV
high: 16,18
low: 6, 11
ablative method goal & indications (3)
destroys TZ, no specimen collection
persistent CIN > 2 years
CIN 2,3 w/ adequate colposcopy
no suspicion for invasive or endocervical disease
ablative methods (2) and healing time
cryothrapy
laser
4-8 weeks
excision treatment goals & indications
removes entire TZ, provides a diagnostic specimen
inadequate colposcopy
high grade lesions/atypical glandular cells
CIN 2+ or recurrent CIN 2,3
