Under 21
21-29
30-65
65 and over
After Hysterectomy
Under 21 = NO SCREENING
21-29 = Cytology alone every 3 years
30-65 = HPV and cytology COTESTING every 5 years
65 and over = No screening folowing adequate negative prior screening
After Hysterectomy = NO screening
What is the stepwise progression from NORMAL cervical tissue to cervical cancer?
Normal –> LSIL –> HSIL–> Cervical cancer
What does ASC-US stand for?
Atypical squamous cells of undetermined significance
What does LSIL stand for?
Low grade squamous intraepithelial lesions
If your patient presents with LSIL, what is the next best step?
Colposcopy
What does HSIL stand for?
High grade squamous intraepithelial lesions
What is a colposcopy?
Directed biopsy for diagnosis and treatment planning of the cervix
During a colposcopy, the cervix is washed with a _______________ which dehydrates cell and large nuclei of abnormal cells and turns them white
During a colposcopy, the cervix is washed with a 3% acetic acid which dehydrates cell and large nuclei of abnormal cells and turns them white
What are the specific visual changes OB/GYNs are looking for during a colposcopy?
Acetowhite changes
