ATYPICAL
SQUAMOUS CELLS
ATYPICAL SQUAMOUS CELLS
Abnormal cells are seen due to an infection or irritation or may
be precancerous
Least reproducible of cytological categories
Low risk of invasive ca (0.1-0.2%)
CIN 2,3 prevalence higher with ASC-H
ASC-H should be considered to represent equivocal HSIL
ASC-US
Initial evaluation may be by 3 Approaches:
2 repeat cytological exams performed at 6 month intervals
Testing for High-Risk HPV
Single colposcopic exam
REFLEX TESTING: refers to testing for high risk HPV at the time of initial
screening. This spares 40-60% of women from undergoing colposcopy.
Prevalence of HPV DNA positivity changes with age among women with
ASC-US
HPV testing only if 21years or over.
HPV testing more efficient in older women with ASC-US
because it refers a lower proportion to colposcopy
Recommended Management of Women
with ASC-US
ASC-US, HPV “-”: Repeat cytology 12 months
ASC-US, HPV “+”: Colposcopy
Negative colpo: do ECC
Unsatisfactory colpo do ECC
Satisfactory colpo,
with lesion present in TZ ECC (Acceptable)
POST COLPOSCOPY:
ASC-US, HPV “+”, No CINdo HPV* @ 12 months
-or- repeat cytology @6,12 months
Note: It is not recommended to perform HPV testing at intervals of < 12 months.

ASCUS
Recommended Management
of ASC-US
Excisional procedures unacceptable for ASC-US unless CIN II-III proven
on histology
Follow up – with REPEAT 6 monthly CYTOLOGICAL TESTING is
recommended, until two consecutive negative results for CIN or
malignancy are obtained. Then annual Follow up is recommended.
On a Repeat test if ASC-US or greater cytological abnormality is found
Colposcopy is recommended
Recommended Management of Women
with ASC-H (CANNOT EXCLUDE HSIL)
All should undergo Colposcopy
In women in whom CIN 2,3 is not identified at coloposcopy,follow up:
owith HPV testing at 12 months
Or
oCytological testing at 6&12 months is acceptable
On repeat Cytological testing, refer to Colposcopy, if
Subsequently test ‘+’ for HPV
Subsequently have ASC-US or greater

LSIL
Cytological diagnosis of LSIL, 2% of women
2nd most common abnormal cytology report (ASC-US is most common)
85% with LSIL, have biopsy-confirmed CIN
18% CIN II-III
.03% invasive cervical cancer
LSIL is highly predictive of HPV infection
COLPOSCOPY: recommended with LSIL

ECC is preferred for
Non-pregnant women in whom no lesions are identified
Women with an ‘unsatisfactory colposcopy’

In the absence of histologically identified CIN, diagnostic excisional or

0.45% OF cytology reports

Managing Women with HSIL
UNACCEPTABLE STRATEGIES
Ablation is unacceptable in the following circumstances:
Colposcopy has not been performed
CIN II-III is not identified histologically
ECC identifies CIN of any grade
Triage utilizing either of the following is unacceptable
Repeat cytology
HPV DNA testing
SIL in Pregnancy
Aim of Colposcopy is to Identify invasive Ca
Lesser lesions never treated
Colposcopy is preferred for pregnant, non-adolescent with LSIL, HSIL
In LSIL Deferring Colpo until at least 6 wks PostPartum is acceptable
In HSIL Colposcopy is recommended Performed by experienced
clinician
SIL in Pregnancy
Biopsy of lesions suspicious for CIN II-III or cancer is preferred
Biopsy of other lesions is acceptable
ECC is unacceptable in pregnancy
Re-evaluation with cytology / colposcopy is recommended no sooner
than 6 weeks PP
ASCUS & LSIL in ADOLESCENTS
Adolescent women Should not be screened unless they have been
sexually active for 3 years
HPV testing is unacceptable for adolescent with ASCUS or LSIL
>80% of sexually active adolescents test + for HPV over a 2 year obsv.
period
If HPV testing was performed, the results should not influence
management
With LSIL, follow-up with annual cytological testing is recommended
91% show regression at 36 months
CIN III before age 20, RARE
LSIL in POSTMENOPAUSAL WOMEN
Prevalence of HPV, CIN II-III decline with age in women with LSIL
Manage less aggressively, triage using HPV may be attractive
Postmenopause with LSIL, should be managed the same as
premenopausal women with ASC-US
Postmenopausal & immunosuppressed women with ASC-US should be
managed in the same manner as women in the general population.
ATYPICAL Glandular
Cells
ATYPICAL GLANDULAR CELLS
0.2% of Pap results
High incidence of underlying neoplasia (9-38% AGC have associated
neoplasia CIN 2 or 3, AIS, Cancer)
Both Cytology or HPV lack sensitivity to be used alone as a triage test.
ATYPICAL GLANDULAR CELLS
3 Categories:
AGC, NOS

AIS (adenocarcinoma in situ)
ATYPICAL GLANDULAR CELLS
INITIAL EVALUATION includes multiple tests
Colposcopy & ECC for all AGC

Endometrial evaluation ( if Age >35 yrs)
Diagnostic excisional procedure necessary inspite of initial negative
testing (if AGC favor neoplasia or AIS)

TOP 10 KEY POINTS
1.Initiate Pap smears at age 21, or 3 years after onset of sexual
intercourse
2.Excisional procedures unacceptable for ASC-US unless CIN II-III
(histology)
3.REFLEX testing with ASC-US spares 40-60 % colposcopy
4.ASC-H should be considered to represent equivocal HGSIL
5.HPV Screening used only for women >30 yrs.
6.For CIN I: cytological follow-up is the only recommended management
option, regardless of whether the colposcopic exam is satisfactory.
