Which oncogenic HPV subtype is the most likely to be persistent?
|
Type 16
|
|
What are the names of the oncogenic genes in the HPV virus? What proteins do they bond to?
|
E6 --> binds p53 and degrades it. Loss of p53 = damaged cells mutate.
E7 --> binds with pRb (retinoblastoma tumor suppresser) and allows damaged cells to survive (pRb inactivates damaged cels) |
|

|
70% oncogenic types
90% low risk types |
|
When should pap smear testing begin?
|
3 years after sexual intercourse initiation or age 21.

|
annual until 30, after 30 women with 3 negatives can undergo q3 yr testing
|
|

|
1 year after a negative Pap and positive HPV test, a patient is retested and the same results occur. What is the next step?
|
colposcopy
|
|
When should one stop screening for cervical ca?
|
ACS - age 70.
USPSTF - age 65 ACOG - continue to screen women who are sexually active with multiple partners or women with history of abnormal tests. |
|
A woman has a hyst and has always had normal pap smears. Does she need vaginal paps?
What about a women who has a hyst for dysplasia? |
normal paps --> no need for vaginal pap.
h/o high grade CIN --> can d/c screening after 3 consecutive neg tests. |
|
A woman has an ASCUS pap. What are the three options for triage of this result?
|
Repeat cytology at 6 & 12 mos, colpo, or HPV testing.

|
Colposcopy
|
|

|
Pap at 6 &12 or HPV in 12
|
|
What is the management of LSIL or ASCUS during pregnancy?
|
NO ECC. Defer colpo til 6 wks PP ok. If they have initial colpo that is negative, no further colpo or pap during pregnancy.
|
|
What are the options for an HSIL pap?
|

|
AGUS pap --> negative colpo, HPV positive --> Pap and HPV negative at 6 mos -->?
Pap ASC or > or HPV positive at 6 mos |
routine screening.
repeat colpo. |
|
LSIL or HPV + ASCUS --> CIN 1 on colposcopic biopsy.
|
DO NOT TREAT CIN 1.
Repeat pap in 6 and 12 mos, or HPV testing in 12 mos. |
|
HSIL pap --> CIN 1 on colpo biopsy
|
If colpo unsat -> diagnostic excisional procedure.
If Colpo satisfactory -> repeat 6 mo colpo&pap, or diagnostic excisional procedure. |
|
Adolescent with ASCUS or LSIL pap
|
Repeat pap at 12 mos. If HSIL or >, colpo. If <HSIL, repeat cytology 12 mos.
|
|
Adolescent with CIN 2 or 3-NOS
|
If colpo satisfactory, can monitor q6 mos for up to 2 years (24 mos). After 2 negative paps, can return to routine screening.
OR Treat. |
|
When should an adolescent absolutely be treated with a therapeutic procedure?
|
if CIN 3 specified, CIN2 or 3 persists for 2 years, or colpo is unsatisfactory.
|
|
Management of AIS in a woman who desires fertility?

1 in 135
|
|
You biopsy what appears to be a tumor. The result comes back with invasion <3 mm. What should you do?
The result comes back CIN. What should you do? |
In both cases, cone biopsy.
|
|
Define Stage I, II, III, IV for cervical cancer by organ involvement.
|
I = confined to cervix
II = spread beyond cervix but NOT to pelvic side wall or distal 1/3 vagina III = pelvic wall/hydro/lower 1/3 vag IV = met to other organs (bowel, bladder, beyond) |
|
What is the difference between IA and IB in cervical cancer staging?
|
IA = microscopic Or invasion<5 mm, spread <7 mm
IB = clinically visible or >5 mm invasion/ >7 mm lateral spread |
|
Cervical cancer : difference between IA1 and IA2
|
IA1 = invasion < / = 3 mm
IA2 = invasion > 3 to 5mm On both lateral spread <7 mm |
|
Cervical Ca: difference between IB1 and IB2
|
IB1 visible lesion <4 cm
IB2 visible lesion >4 cm |
|
Cervical CA: IIA versus IIB?
|
IIA no obvious parametrial involvement
IIB obvious parametrial involvement |

|
Can you ever do a cone biopsy for cervical CA? Whats the f/u after?
|
only for IA1 desiring feritility. Good prognosis if neg margins. Need pap q6mo for several years.
|
|
What is the treatment for IA2 cervical ca?
|
Cone vs trachelectomy vs simple hyst vs radical hyst.
establish diagnosis with cone. data for cone suggests higher rate of recurrence. LVSI positively correlated with recurrence, as well as depth of invasion. Simple vs radical hyst. Depth of invasion <5 mm in one study no nodal mets. Do nodes if LVSI present. |
|
Disease related deaths in IA1 versus IA2?
|
0.76% versus 1.8 %.
|
|
Treatment for IB1 cervical ca?
|
Radical hyst and radiation equal.
|
|
What are indications for post radical hyst radiation?
|
Positive or close margins, disease extension into parametria, lymph node mets
GOG trial comparing IB tumors with >1/3 stromal inv, LVSI, tumor >4 cm - postop pelvic radiation reduced recurrence risk but did not impact overall survival |
|
Treatment for IB2 cervical ca?
|
rad hyst ok, but if imaging identifies risk factors (bulky disease, PET shows lateral spread) consider radiation instead
|
|
Does chemo-radiation improve survival?
|
Cisplatin adjuvant increased progression free and overall survival.
|
|
What about stage IIA?
|
Radical hysterectomy ok.
|
|
What tumor size is the limit for trachelectomy?
|
2 cm
