Cervical Intraepithelial neoplasia Flashcards
Where does cervical cancer fall in terms of the incidence of gyn malignancies?
3rd
In whom is incidence and mortality of cervical cancer the highest?
Incidence highest in hispanic women, but mortality highest in blacks
When was it discovered that HPV causes cervical cancer?
2008
Is HPV screening by itself recommended?
Not currently–combined with Pap
What is an ectropion? Is this normal?
Cervix is inverted– this is normal
What is the role of acetic acid in determining cervical abnormalities?
visualize abnormal areas by dehydrating so that squamous cells with dense nuclei will appear white
What are nabothian cysts? Treatment?
Cervical mucus gland that is plugged
Self limiting and asymptomatic
What is the recommendation for pap smears? (when start, how often, what is done)
- Begin at age 21 (regardless of age at first intercourse)
- Tested with cervical cytology alone (not HPV)
- q 3 years
Why is co testing for HPV not recommended for pap smears for 21-29 years?
high prevalence in 21-29 years and low incidence of cervical CA
When does HPV co-testing begin? How often? At what age does it stop?
- Co-test at 30-65 q 5 years
- Screen cytology alone 1 3 years
Who should be screened for cervical cancer more often?
-immunocompromised
-h/o cervical CA
-
When do Pap smears stop? Who is the exception to this?
65, unless immunocompromised or has a h/o cervical CA
Do women with a total hysterectomy need a pap smear?
Nah
Are pap smears and HPV testing recommended for below 21 years?
No
True or false: most epithelial abnormalities require further assessment
True
What is a colposcopy?
Microscope on wheels for cervical screens
What are the treatment modalities for cervical cancer?
Cryotherapy
-Excisional (LEEP)
What is the LEEP procedure?
Loop electrocautery excision
When is a cone excision indicated?
Concern for deeper carcinoma
What percent of cervical cancer is SCC?
90%
Adenocarcinomas of the cervix are most commonly (endophytic or exophytic)? What are the characteristics of this in terms of malignancy?
Endophytic
Aggressive
What are the lesions that are commonly found with adenocarcinoma of the cervix?
Skip lesions–start from multiple areas
Does microinvasion apply to adenoCA?
No
What are the s/sx of cervical CA? (if any)
- Vaginal d/c
- Odor
- Abnormal bleeding
- Postcoital bleeding
What are the structures that are affected with direct extension of cervical CA?
- Involvement of the pelvic side wall
- venous compression
- Hydroureter
What is the only gyn CA that is staged clinically?
Cervical
What are IVPs? What are they used for?
Intravenous pyelogram– an x-ray examination of the kidneys, ureters and urinary bladder that uses iodinated contrast material injected into veins
What is stage 0 cervical CA?
CIS
What is stage 1 cervical CA?
carcinoma confined to the cervix
What is stage 2 cervical CA?
Carcinoma extends beyond the cervix either to the vagina or parametrium
What is stage 3 cervical CA?
Lower 1/3 of the vagina or the pelvic side wall
What is stage 4 cervical CA?
CA extends beyond the true pelvis or involves the mucosa of the bladder
Treatment for cervical CA depends largely on what?
Staging
What is the treatment for IA, IA2, IIB and above?
- IA1 = Excise
- IA2 = Radial hysterectomy
- II and above = XRT and chemo
What is excised with a radical hysterectomy? (4)
- uterus + ovaries
- pelvic side wall
- upper 2/3 of vagina
- pelvic nodes
What are the risks of radical hysterectomy? (3)
- Ureteral occlusions
- Ureteral fistula
- Bladder atony
Why bladder atony with radical hysterectomy?
Damage to the nerves
What are the two different XRTs for cervical CA?
EBRT
Brachytherapy
What is brachytherapy?
Intracavitary radiation –Place radioactive things in cervix to crush CA
What are the complications of XRT to the cervix?
- Ileus
- Urinary frequency
- dyspareunia
What is pelvic exenteration?
Radical procedure for recurrent cervical CA
–Radial hysterectomy + cystectomy, and rectum removal
True or false: HPV vaccines must be given before or at the onset of sexual activity to be effective
True
What is the difference between partial, total, and radical hysterectomy?
Partial = just the uterus Total = uterus + cervix Radical = above + vagina
What is the concern with performing the LEEP procedure?
If take too much tissue, may cause cervical issues
