1
Q

Cervical Intraepithelial Neoplasia (CIN)

A

The abnormal growth of potentially precancerous cells in the cervix. Most cases remain stable or are eliminated by the host’s immune system without intervention

Q

ASC-H

A

Cytologic changes suggestive of HSIL, but lacking definitive interpretation
Has a significantly higher predictive value for diagnosing CIN2 or CIN2 than ASC-US Paps

Q

Management of ASC-US Paps

A

Repeat Pap smear until there are 2 consecutive normal Paps
OR
Immediate colposcopy
OR
DNA testing for high-risk types of HPV
Those women with ASC-US Pap smears who test positive for high-risk HPV should undergo colposcopy
Those who test negative should have a Pap in 1 yr
A woman with ASC-US and positive HPV results has the same risk for high-grade dysplasia as if she had an LSIL Pap smear and thus requires colposcopic eval
A woman with ASC-US and negative HPV can be reassured, treated as if she had a nl Pap smear, and followed with a Pap in 1 yr

Q

Atypical glandular cells

A

Atypia that is of glandular rather than squamous origin
More likely to be serious with glandular abnormalities than an ASC-US Pap, so the work up is more aggressive than with an ASC-US Pap
If ID-ed, it will also report endocervical adenocarcinoma and adenocarcinoma in situ

Q

Atypical glandular cell management

A

All pts with AGC Pap smears should have colposcopy with endocervical sampling with the exception of pts with atypical endometrial cells
In those pts who have an AGC Pap smear with an abnormal bleeding hx, or who are >35 yrs, an endometrial bx should be added to the initial colposcopy and endocervical sampling

Q

LSIL management

A 
Referral for colposcopy
May do "watchful waiting" if under 25 yoa
Endocervical sampling (along with biopsies of any lesions visualized on colposcopy)is considered preferred in pts with unsatisfactory colposcopy or in those with satisfactory colposcopy and no lesion identified.

Q

Where are abnormal biopsy samples from LSIL colposcopy sent?

A

Pathologist determines if there is any evidence of precancerous changes, called cervical intraepithelial neoplasia
These changes are categorized as being mild (CIN1) or moderate to severe (CIN 2 or 3)

Q

Lesion <2 cm Confined to the vulva or perineum and with stromal invasion >1 mm No nodal metastasis
