When to Get Pap Smears
ACOG Recommendations
When to Get Pap Smears ACOG Recommendations –1st Pap Smear at age when patient becomes sexually active (or by age 18)
When to Get Pap Smears ACOG Recommendations –1st Pap Smear at age when patient becomes sexually active (or by age 18) –Yearly pap smears thereafter

Performing Pap Smear
Cervix visualised – superficial layer of cells in cervical canal taken on a spatula or swab stick – spread on a slide, fixed and stained with Papanicolou stain – examined under mircoscope

Evaluating the Pap Smear
First, the smear is evaluated for adequacy of sample

What to Inform Patients Prior to Obtaining Pap Smear
No douching or usage of vaginal medications, lubricants, or spermicides within 2-3 days of exam (these products may hide abnormal cells)

Improving Access to Pap Smears
50% of patients who die of cervical cancer have never had a Pap Smear
Improving Access to Pap Smears 50% of patients who die of cervical cancer have never had a Pap Smear Uninsured, older patients and those who live in rural areas have limited access to Pap Smears
Improving Access to Pap Smears 50% of patients who die of cervical cancer have never had a Pap Smear Uninsured, older patients and those who live in rural areas have limited access to Pap Smears These groups must be targeted to reduce rates of cervical cancer.
Treatment
Surgery for early stage 1
Treatment Surgery for early stage 1 Stage 2 onwards radiotherapy and / or surgery
Prognosis
CIN cure rate 95 – 100%
Prognosis CIN cure rate 95 – 100% Stage 1 – after treatment – 5 yr survival 80%
Prognosis CIN cure rate 95 – 100% Stage 1 – after treatment – 5 yr survival 80% Decreased to 14 % for Stage 4
