-Age 30-65- Pap w/ HPV testing every 5 yrs or pap alone every 3 years
-In 2016: women 25 and up consider primary HPV screening as alternative to cytology based screening but cytology or co-testing still preferred
123
When should you stop pap smear screening?
1. 65 and over
2. Total hysterectomy for benign indications
3. H/o hyster for CIN 2/3 or w/ h/o CIN2/3- continue pap smear alone every 3 years until 20 yrs after initial post treatment surveillance

132
F/up for ASC-US cytology & neg HPV?
cotesting in 3 years
133
F/up for women 30 and, cytology neg, HPV +?
1. Repeat cotest 12 mos, if pap ASCUS or higher or HPV +, colpo, if both normal cotest in 3 years
2. Immediate HPV 16, 18, if pos-> colpo, if HPV neg cotest 12 m
134
Pap-ASCUS >25 yo
1. Traige testing w/ HPV preferred
high risk HPV +--> colpo
Negative-->routine age based testing
2. If no HPV testing done: repeat pap in 12 m
If ASC-> colpo
135
ASCUS Pap 21-25 yo
Pap Q 12 m
HPV and colpo NOT done routinely, only if Pap =HSIL or >, at subsequent paps even ASC gets a colpo
HPV is common due to repeat infections (not persistent infx which is a cancer risk)

consider similar to HSIL, risk of CIN2,3 is 50%
COLPOSCOPY, NO HPV TESTING
137
LSIL <25 yo
