Q

What can the 2001 Bethesda System tell us about a pap smear?

A
    • Specimen type (conventional or liquid-based)
    • Specimen adequacy = satisfactory for eval or unsatisfactory (not enough cells)
    • General categorization: negative/abnormal/other
      1. - Organisms
      2. - Other non neoplastic findings: inflammation, radiation, IUD
      3. - Epithelial cell abnormalities

Q

In the 2001 Bethesda System, what does general categorization tell us about the pap smear?

A
  1. Negative for intraepithelial lesions or malignancy
  2. Abnormality of epithelial cell: see interpretation/result for details

Q

Cervical changes from NL => cervical cancer

A
  1. NL
  2. LSIL
  3. HSIL
  4. Cervical cancer
20
Q

Managment of a women w/ atypical squamous cells of undetermined significance (ASC-US) on cytology

A
  1. Repeat cytology at 1 year
    1. (-) => back to routine screening
      • ASC => + colposcopy
  2. Do HPV testing
    1. (-): repeat cotesting @ years
    2. (+; managed same as LSIL): coloscopy
21
Q

What are the guidelines for managment of a women w/ LSIL pap smear?

A
  1. LSIL with (-) HPV test
  2. LSIL with no HPV test
  3. LSIL with (+) HPV test
22
Q

What are the guidelines for managment of a women w/ LSIL and (-) HPV test?

A
  1. Repeat co-testing at 1 year (preferred), but colposcopy is acceptable
    1. @ co-testing:
      1. If cytology and HPV negative => repeat at 3 years
      2. If ≥ASC or HPV positive => then colposcopy
23
Q

What are the guidelines for managment of a women w/ LSIL and no HPV test or a (+) HPV test?

A

Colposcopy

24
Q

What are the guidelines for managment of a women w/ HSIL?

A
  1. Immediate loop electrosurgical excision
  2. Colposcopy (w/ endocervical assessment)
25
**Gold standard** for diagnosis and treatment planning of abnormal pap smear
**_Colposcopy_ w/ directed biopsy;** **cervix is washed w 3% acetic acid, which dehydrates cell and large nuclei of abnormal cell turns white (acetowhite changes)**
26
To be adequate, what **must** be seen on coloscopy?
**SQJ**
27
What are the abnormalities you are looking for on **Colposcopy**?
1. Acetowhite changes 2. Punctuations (tiny blood vessels) 3. Mosaicism 4. Abnormal blood vessels 5. Masses
28
What is CIN for: 1. Acetowhite changes 2. Punctuations (tiny blood vessels) 3. Mosaicism 4. Abnormal blood vessels 5. Masses
1. Acetowhite changes: CIN 1 2. Punctuations (tiny blood vessels/dots): CIN 2, maybe 3 3. Mosaicism: BAD; almost always CIN 3 4. Abnormal blood vessels 5. Masses
29
What is seen in **high grade lesions (CIN 3)?**
1. LOTS of **acetowhite changes** 2. **Mocaicism**
30
What are the **2 main treatment options** for abnormal pap smears? Mark most common
1. **Ablative** (cryotherapy or laser) = destroy cervical tissue 2. **Excisional** (CKC or LEEP) **\*\*\***
31
What are the 2 types of exisional procedures?
* 1. **CKC** = cold knife cone * 2. **LEEP** = loop electrode excisional procedure
32
WHEN are **excisional** techniques done? (3)
1. **(+) ECC** (endocervical curettage) =\> perform CKC 2. **Unsatisfactory colposcopy** (NO SCJ) 3. **Discrepancy between pap and biopsy** (High grade pap, but negative colposcopy)
33
4 **risks** of with **excisional** **procedures** for cervical neoplasia?
1. ↑ risk of cervical incompetence causing pregnancy loss in 2nd trimester 2. ↑ risk of preterm premature rupture of membranes (PPROM) 3. Cervical stenosis 4. Operative risks (bleeding, infection)
34
Median age of diagnosis of cervical cancer When do precursor lesions precede invasive carcinoma?
* **47 YO** * 10 years before
35
How is **cervical carcinoma** staged?
**- Clinically** by: 1. **PE** 2. **Radiologic exams** --\> CXR and skeletal XR's + intravenous pyelogram 3. Cystoscopy 4. Sigmoidoscopy 5. Liver function studies
36
How is **microinvasive** cervical carcinoma managed clinically? **Invasive**?
1. **Cold knife cone** or **hysterectomy** 2. **Radical hysterectomy** w/ **LN dissection**
37
Prevention of cervical cancer (4)
1. Abstinence/ decrease partners 2. Contraception 3. Regular exams and pap smears (dec by 40%) 4. HPV vaccine
38
**HPV vaccine recommendations**
- All M/F **9 to 45 YO**
39
How many injections are in a series of **HPV vaccine** and what is the recommendation for scheduling?
**3 injections:** * 1st dose * 2nd dose 2 months later * 3rd dose 6 months from the first (can still be given if interval varies) In children \<15 YO: give 2 doses separated by **6-12 month**
40
If a patient already has an **abnormal pap** can they receive an HPV vaccine; what about during **pregnancy** and **breast feeding?**
1. - **YES:** abnormal pap or breastfeeding 2. - **NO:** pregnancy
41
What are the 2 **Gardasil** vaccines?
* 1. **4 strain** (6, 11, 16, 18): protects against 70% * 2. **9 strain** (+ 31, 33, 45, 52, 58)
42
What drug is NO longer on the market for girls 9-25 and protects against 16 and 18?
**Cervarix**
43
List 6 AE's associated with HPV vaccination?
1. Syncope\*\* (most common) 2. Dizziness 3. HA + fever + nausea 4. Injection site rxns (pain, swelling, and redness)
44
If a patient has a **+ pap smear (HSIL),** but a **(-) colopscopy,** what do you do?
**Exision**
45
If a patient has a **unnsatisfactory colposcopy**, and the SQJ cannot be be seen. What do we do?
Excisiojn
