Starting with the end.
Finishing with the prevention.
Don’t need to know the rare types
IIa upper vagina with no parametrial invasion
IIb Parametrial invasion
Most treated with Radiotherapy and chemotherapy
Occasional IIa will get surgery
Treatment: radical radiotherapy and chemotherapy
And how we prevent Cervical Cancer.
Two types of epithelium on the cervix interact to create an area that is vulnerable to the oncogenic HPV virus. The penis does not have this type of interaction
Columnar (produces mucous)
What is metaplasia?
NOTE: This cervix has
had acetic acid applied,
the SCJ is not obvious
with the naked eye or
with out acetic acid.
Normal Process !!
Conversion of a normal glandular epithelium to a normal squamous epithelium
Starts at puberty, accelerates at pregnancy
These cells are uniquely vulnerable to HPV infection.
(Human papillomavirus infection)
(80% of ever sexually active females)
(Cervical Intraepithelial Neoplasia)
(1-3% of those infected with HPV)
(?% Of those with dysplasia who do not get diagnosed and treated)
HSIL high grade
LSIL low grade
‘Persistent infection with one of the carcinogenic types of HPV is a necessary, but not sufficient, cause of both squamous and glandular malignancy.’
Technique described on one of the documents on HOMER
(Technique for obtaining satisfactory pap smears)
Guideline for Screening for Cervical Cancer (on Homer)
Pathologist or cytotechnician create the report.
Bad news: Many ways a pap can be abnormal, and type of change and age of woman dictates next step.
Good news: The pathologist will tell you what to do as part of the report.
Pap Smears: necessary for precancer and cancer to develop.A. Normal Pap, B. ASCUS (not normal, not precancerous…atypical squam cells undet. Significance)C. LSIL-low grade C. HSIL – high grade
Redo pap if you get ASCUS
Squamous necessary for precancer and cancer to develop.
Normal (vast majority)
ASC-H (atyp squam, high grade)
Normal (vast majority)
AGC-(atypical glandular cells)
AdenocarcinomaPap results-see Management of Abnormal cytology in Clinical Practice Guidelines.
Areas of mosaic, punctation, white
epithelium suggest areas of dysplasia.
Biopsy suspicous areas (small, representative sample)
Must treat entire transformation zone:
LEEP (loop electrosurgical excision procedure)-most common
Hysterectomy-rare, usually only if other indications
