Q

what information does the bethesda classification give you?

A

cytology: tells you what the cells from a pap smear LOOK like, NOT what the tissue is (doesn’t Dx the cancer)

Q

what is the bethesda classification system?

A

from American society of colposcopy and cervical pathology: a way of describing pap smears so txt guidlines can be unified worldwide

Q

pap shows ___ cells (what classification is this?)

dysplastic cells. (cytology is bethesda classification)

Q

what if pap result is ASC-H, what do you need to do? why ?

A

“atypical squamous cell - can’t rule out high grade” .. higher rate of HPV infection so you need colposcopy

Q

what is LGSIL? what does management of this depend on?

A

low grade squamous intraepithelial lesion . depends on age and HPV
(status negative HPV test …and under 24- repeat test with only cytology.. and over 24- repeat test with co-test)

Q

why do you need endometrial biopsy if you have AGC results?

A

differentiate between endometrial and endocervical cells

THIS is a high level of concern

A

pap every 3 years

26
Q

Age 25-29: with Hx of normal pap results, how often do you do routine screening?(maybe weeds)

A

pap every 3 years

27
Q

Age 30+ (HPV negative): how often do you do routine screening?(maybe weeds)

A

pap every 3 years BUT prefer co-test every 5 years

28
Q

Age 30+ (HPV positive): how often do you do routine screening?(maybe weeds)

A

HPV typing BUT prefer co-test ever year

29
Q

ASC-US age 21-24(maybe weeds)

A

reflex HPV test, BUT prefer repeat pap in 1 year

30
Q

ASC-US age 24-29(maybe weeds)

A

repeat pap in 1 year, BUT prefer reflex HPV test

31
Q

ASC-US age 30+ HPV negative(maybe weeds)

A

repeat co-testing in 3 years

32
Q

ASC-US age 30+ HPV positive(maybe weeds)

A

colposcopy

33
Q

LSIL age 21-24 (maybe weeds)

A

repeat pap in 1 year

34
Q

LSIL age 24-29(maybe weeds)

A

colposcopy

35
Q

LSIL age 30+ HPV negative (maybe weeds)

A

colposcopy BUT prefer repeat pap in 1 year

36
Q

LSIL age 30+ HPV positive (maybe weeds)

A

colposcopy

37
Q

anyone with ASC-H?

A

colposcopy!

38
Q

HSIL age on anyone over 24? (maybe weeds)

A

colposcopy (or excision txt)

39
Q

AGC on any age? what is the follow-up treatment?

A

vary depending on AGC subcategory but include colposcopy, endocervical and endometrial sampling

40
Q

what is CIN?

A

cervical intraepithelial neoplasia AKA cervical dysplasia. A histological Dx. (CIN 1-3) higher CIN number = worse

41
Q

HIV infection or immunosuppressed pts, proceed to ____ for any pap abnormality!

A

colposcopy!

42
Q

DES exposure pts, what was this known to cause? what is there an increased risk of ?

A

causes abnormalities of uterus and cervix in women who were exposed in utero. higher risk of vaginal cancer

43
Q

DES exposure pts need screening how often?

A

yearly!

44
Q

who is HPV infection most common in ?

A

teens and early 20s

45
Q

vaccines are against what HPV strains?

A

16 and 18

46
Q

screening rules for women under 20years old (weeds)

A

Considered anyone 20 and younger
Very likely to regress spontaneously – Pap should not be done
However, IF Pap is done …
If result is ASCUS, ASC-H or LGSIL, repeat Pap in 1 year
If Pap still LGSIL or less in a year, repeat Pap in 12 months
Colposcopy for HGSIL

47
Q

screening for post-menopausal women (weeds)

A

Often have atrophic vaginal mucosa and cervical mucosa
Atrophic cells can appear dysplastic
Transformation zone often regressed far inside the endocervical canal
Give vaginal estrogen (if no contraindication) and repeat Pap
HPV typing helpful

48
Q

is HPV testing useful?

A

useful for ASCUS to determine txt plan

- more useful in older patients b/c clearance is less likely (those over 25)

49
Q

when did/does gardasil 9 come out?

A

october 2018

50
Q

what was the first gardasil?

A

quadrivalent for 6, 11, 16, 18

51
Q

CIN stages (1,2,3, CIS)

A

1: mild, 2: moderate, 3: severe
CIS: carcinoma in situ

52
Q

CIN peaks in the ___s

A

20s

53
Q

____ in every ___ deaths is cancer related (of any type of cancer)

A

1 in 4

54
Q

FIGO staging of cervical cancer: staging can be based on ___ not ___ findings. why is this important?

A

clinical not surgical findings
- allows staging in areas with limited resources (when surgery not available) .. however its still used in institutions where surgery IS available

55
Q

risk factors for cervical cancer (maybe weeds)

A

Early age at first intercourse
Multiple partners or a partner with multiple partners
Lower socioeconomic group (age at first intercourse?)
Smoking
Immunodeficient
Oral contraceptive use

56
Q

txt for cervical cancer( maybe weeds)

A

Surgery (simple hysterectomy) only for stage IA1; total hysterectomy; or conservative surgery if fertility desired
Greater than IA1 stage needs lymph node dissection and radical hysterectomy (with BSO, LND)
Possible radiation + chemotherapy

57
Q

cervical cancer prevention (maybe weeds)

A

Awareness
Routine Paps
HPV Vaccination
Condom use- prostaglandins in semen fuel dysplasia growth; prevent spread of HPV and other STIs
Dietary (high vegetable consumption decreases risk of acquiring HPV by 54%)

58
Q

what is the GOLD standard in Dx cervical dysplasia and cancer?

A

colposcopy
