Cervical Dysplasia Flashcards

1
Q

what is cervical dysplasia?

A

Dysplasia defined is abnormal growth or development of cells, tissues, or organs.
Pap smear - screen for cervical dysplasia
The pap indicates the amount of “abnormal cell growth” occurring on the cervix.

Q

What are the different categories for the Besthesda system?

A

Squamous Cell (Ectocervical cells)
ASC-US: Atypical squamous cells of undetermined significance
ASC-H: Atypical squamous cells-cannot exclude
high grade squamous intraepithelial lesion
LGSIL: Low grade squamous intraepithelial lesion (CIN 1 and 2)
HGSIL: High grade squamous intraepithelial lesion
(CIN 3 and CIS)
CIS: Carcinoma in situ
Squamous Cell Cancer

Glandular Cell (Columnar cells)
AGC-US: Atypical glandular cells of undetermined significance (endocervical canal)
Can be normal in post menopausal people but always need to do an EMB (endometrial biopsy)
AIS: Adenocarcinoma in situ
Adenocarcinoma

Q

Describe the CIN system:

A 
CIN I/Mild Dysplasia (includes HPV 
    effect)
CIN II/Moderate Dysplasia
CIN III/Severe Dysplasia/CIS
Cancer
19
Q

How do you relate the results of Besthesda and CIN?

A 
Mild = CIN I = LGSIL
Moderate = CIN II = LGSIL/HGSIL
Severe/CIS = CIN III = HGSIL
20
Q

What are some ways that you can get abnormal pap results that are actually BENIGN?

A 
Infection:
  treat accordingly-no repap needed
Atrophic:
  vaginal estrogen and repeat in  6 month/year
ASCUS -high risk HPV (-):
  12 months
  if repeat pap is same ? colposcopy
21
Q

What are NON-benign presentations of pap results? is a colposcopy indicated?

A

ASCUS &+HPV,AGUS,LGSIL,HGSIL/CIS

need COLPOSCOPY

22
Q

how soon should be a colposcopy be scheduled after menses?

A

1-2 weeks

23
Q

If patient is of child-bearing age, you should always test for ______ before doing a colposcopy?

A

pregnancy!!

24
Q

what will a colposcopy tell you?

A

acetic acid will turn abnormal areas white

25
Q

If a pregnant woman has an abnormal pap smear, what is the goal?

A

rule out invasive cancer.

26
Q

When is treatment initiated in pregnant woman with abnormal pap smear?

A

treatment is deferred until 6 weeks postpartum unless cancer. a very small (.4%) actually progress to cancer.

27
Q

Do most regress after delivery of the baby?

A

yes

28
Q

Describe a colposcopy in pregnancy:

A
  1. Colposcopy with biopsy before 12 wks
    (No ECC done , to see if HGSIL or CA because it can dilate the cervix and cause a miscarriage )
  2. ASCUS HPV (+) colposcopy or defer till PP
  3. Mild dysplasia colposcopy or defer till PP
  4. Mod/Severe dysplasia: colp early, repap w/ colp at 20 wks
    (No biopsies or ECC done at 20 wks - unless obvious CA)
29
Q

What treatment options are available?

A

Cryotherapy:
Effective for small non-invasive lesions
freezing cervix with liquid NO2 probe; depth of 4-5 mm.;

CO2 Laser Ablation:
Larger visible lesions
Burning cervix with CO2 laser; depth of 6-7 mm
Need anesthesia

LEEP/LEETZ( loop electrical excision proc.):
Excisional biopsy for CIN
Cuts to depth of 6-10 mm.
Tissue to pathology

Conization:
For severe dysplasia (CIN III)
Cold-knife cone (surgical blade) or LEEP
Used for areas that involve ecto/endo tissue

Hysterectomy

30
Q

How will you treat for small non-invasive lesions?

A

cryotherapy

31
Q

How will you treat for larger, visible lesions?

A

c02 laser ablation

32
Q

How will you treat for CIN

A

LEEP

33
Q

How will you treat for severe dysplasia?

A

Conization

34
Q

What is the definitive treatment?

A

hysterectomy is serious enough

35
Q

What are 70% of cervical cancers due to?

A

HPV 16 and 18

high risk

36
Q

T/F: most HPV infections lead to cancer

A

FALSE

most new infections will clear within one year, and 95% by 2 years.

37
Q

What does HPV persistence signify?

A

Infection detected at more than one visit (usually 4-6 months apart)

Most important predictor of high grade cervical cancer precursors

38
Q

What is a reflex HPV?

A

it is added onto a pap smear for high risk patients. It determines the DNA sequence

39
Q

In what population is a co-test indicated?

A

> 30 years old

40
Q

What is cervista

A

only tests for HPV 16 and 18

41
Q

Describe the HPV immunizations available

A 
CERVARIX:
Indicated for the prevention of cervical cancer
Covers HPV strains 16 and 18 
Approved for males/females ages 10-25
3 dose series, 0, 1, and 6 months
Not to be given in pregnancy

GARDASIL:
Same as other except covers types 6,11,16,18

42
Q

Who should get the HPV vaccine?

A

Indicated in girls and women;boys and men ages 9-26 for the prevention of the following diseases caused by HPV types 6, 11, 16, and 18:

  1. Cervical cancer
  2. Cervical, vaginal and vulvar precancerous or dysplastic lesions
  3. Genital warts (condyloma acuminata) (boys and men)

Ideally vaccine should be administered before onset of sexual activity, but males and females who are sexually active should still be vaccinated.

43
Q

Is the vaccine effective against existing disease?

A

evidence does not show that

Males and Females not yet sexually active can be
expected to have the full benefit of vaccination

Sexually active males and females may not have full
benefit because they may have been infected with
vaccine HPV types, however:

44
Q

HPV vaccine for pregnant people:

A

Initiation of the vaccine series should be delayed
until after completion of pregnancy

If pregnant after initiating the vaccination series, remaining doses should be delayed until after pregnancy

If a vaccine dose administered during pregnancy,
no indication for intervention

Exposures to vaccine in pregnancy should be
reported (800) 986-8999
