- Which 2 HPV strains cause HIGH-GRADE cervical cancers?
- Which 2 HPV strains cause genital warts (LOW GRADE lesion)
- HPV 16, 18** –> HIGH GRADE
- HPV 6,11 –> LOW GRADE
What is the only modifiable risk factor to reduce risk of cervical cancer?
- SMOKING *******
Other risk factors:
- Multiple sexual partners
- Young age at first intercourse
- HIV + Organ transplant
- STI’s
- DES exposure
- High parity
What are the pap smear screening guidelines based on age for …
- Under 21?
- 21-29?
- 30-65?
- 65+?
- no screening
- cytology alone every 3 years
- HPV and Cytology “cotesting” every 5 years (preferred)
- No screening following adequate negative prior screening
What are the pap smear screening guidelines following hysterectomy?
No screening
If 40 y/o patient had an unknown HPV status on her last pap result.
When is next pap?
3 years
(when unknown)
What 6 things can the 2001 Bethesda System tell us about a pap smear?
- Specimen type
- Specimen adequacy = satisfactory or unsatisfactory (not enough cells)
- General categorization
- - Organisms
- Other non neoplastic findings: inflammation, radiation, IUD
- Epithelial cell abnormalities
What are the guidelines for managment of a women w/ atypical squamous cells of undetermined significance
(ASC-US) on cytology?
Repeat cytology at 1 year and do HPV testing
What are the guidelines for managment of a women w/ atypical squamous cells of undetermined significance
(ASC-US) after repeat cytology at 1-year if….
Result is negative or ≥ASC is found?
then back to routine screening (if Negative)
or do colposcopy ( ≥ASC)
What are the guidelines for managment of a women w/…
Atypical squamous cells of undetermined significance
(ASC-US) if…
HPV testing is positive
HPV testing is negative?
- Positive = managed same as LSIL —> colposcopy
- Negative = repeat cotesting at 3 years
What are the guidelines for managment of a women w/…
LSIL and negative HPV test?
- Repeat co-testing at 1 year (preferred)
- but colposcopy is acceptable
- If cytology and HPV negative —> repeat at 3 years
- If ≥ASC or HPV positive –> then colposcopy
What are the guidelines for managment of a women…
1) w/ LSIL and no HPV test
or
2) LSIL with a positive HPV test?
Colposcopy
What are the guidelines for managment of a women w/ HSIL?
- I_mmediate loop electrosurgical excision_
or
- Colposcopy (w/ endocervical assessment)
What is the gold standard for diagnosis and treatment planning of abnormal pap smear?
- Colposcopy w/ directed biopsy
What are 2 CONCERNING findings on Colposcopy?
(that may indicated cervical cancer)
- Mosaicism***
- - Abnormal blood vessels****
Other colposcopy findings
- Acetowhite changes
- Punctuations (tiny blood vessels)
- Masses
Which 3 instances require excisional techniques for cervical neoplasia?
Cold Knife Cone (CKC)
Loop Electrode Excision Procedure (LEEP)
- + Endocervical curettage (needs cold knife cone)
- - Unsatisfactory colposcopy (No SCJ)
- - Substantial discrepancy btw pap and biopsy (i.e., high grade pap, but negative colposcopy)
