GYN (part 3)-Exam 2 Flashcards
Papanicolaou test – “Pap Smear”
* Routine screening for what?
* May also screen for what?
* When should you should you start screenign?
* What should be biopsied?
- Routine screening for cervical cancer, or cell changes known to lead to cancer
- May also screen for HPV
- Should start screening at age 21, even if sexually active earlier.
- ALL visible abnormal cervical lesions should be biopsied
Under notes
What is the timeline for paps?
Anyone with a cervix between the ages of 21 and 30 should get a Pap smear at least once every three years.Between the ages of 30 and 65, you should have one every five years.
How do you do the brush at the cervix?
Brush is the best at he squamocolumnar junction.
Where does 90% of squamous cervical intraepithelial neoplasia (CIN) occurs?
within the transformation
* This is why it is so important to get cells from the squamous epithelium (exocervix) and the columnar epithelium (endocervix).
She said FYI
Cervical Intraepithelial Neoplasia (CIN)
* Hormonal influence of puberty + changes in vaginal pH causes what?
causes squamous margin to encroach on the single-layer, mucous secreting epithelium, creating an area of metaplasia - “transformation zone”
Cervical Intraepithelial Neoplasia (CIN): HPV types
* What are the high risk HPV cancer related types
* HPV types associated with genital warts?
Human papillomavirus (HPV) types.
* High Risk HPV-cancer related types: 16 and 18 (70%), 31, 33 and 45
* HPV types associated with genital warts: 6 & 11 (90%) (condyloma acuminata)
Cervical Intraepithelial Neoplasia (CIN)
* What are the classification?
Describes degree of abnormality
* CIN 1 = LSIL
* CIN 2, 3 = HSIL
U. S. Preventive Services Task Force Recommendation: PAP
* When do you do screenings? (average risk group)
- Women aged 21-29 - screening with cytology (pap smear or liquid based) every 3 years
- Women aged 30-65 - screening with cytology every 3 years + HPV testing every 5 years or with co-testing (both) q 5 years
U. S. Preventive Services Task Force Recommendation: PAP
* What is the screening timeline for high risk group?
ANY previous abnormal cytology screening or HIV or DES exposure in utero -> yearly screening
American Cancer Society Guidelines: pap+HPV
* Screening should begin when?
* What is the timeline?
* Who should stop cervical cancer screening?
- Screening should begin at age 25
- Women aged 25-65 should have HPV test q 5 years combined with PAP test or a PAP test alone q 3 years
- Women over 65 who have had regular screenings for past 10 years with no history of CIN2 or more serious diagnosis should stop cervical cancer screening
Cerival cancer
* What is the most primary initating event? What is it?
* What are other risk factors?(4)
HPV infection is the primary initiating event
* HPV a double stranded DNA virus infects epithelium near transformation zone.
* HPV 16 & 18 most frequently associated
Other risk factors: Multiple sex partners, first intercourse <18yo, smoking, STD and DES exposure
- Most women are infected with HPV, but most clear it.
- Some women keep a chronic infection, and it is thought there is a genetic predisposition associated
Screening for cervical cancer
* What test
* make take how long to progress?
* Primary prevention is what?
- Pap test
- May take years to progress from dysplasia to cancer
- Primary prevention is via HPV vaccines
Clinical Presentation: Cervical cancer
* What are the early stages and later stages?
Early stages are asymptomatic
Later stages:
* Post-intercourse bleeding
* Intermenstrual cycle bleeding
* Persistent yellow discharge
* Foul smelling discharge
* Heavy menstrual bleeding
* Pelvic/sacral pain
* Most common presentation of later stage cancer is a visible lesion on the cervix
cervix cancer
* how do you dx it?
- Most found during Pap test screening of asymptomatic women
- Colposcopy with biopsy
- MRI or PET-CT used for staging
cervix cancer
* What are all the different treatments? (5)
How do you do cryotherapy?
Cervix cancer
* How do you conization/cone biopsy?
Cervix cancer
* How do you do a loop Excisional Biopsy?
