GYN malignancy Flashcards
what is endo CA
most common
- epithelial tumor
2 types of edno CA
type 1 - E dependent
type 2 E indep
risk factors for E dep
- obesty
- chronic anov (PCOS)
- unopposed E use
- tmoxifen
- early menarche/late meno
- Fam hx
prevention
avopid risk factors
screening for endo**
none
3 warning signs for endo
- post-meno bleeds
- irreg vag. bleeds
- abdo bloating, pain, bowel sx
diagnostic test for endo ca
- endo biopsy with pipelle instrument
- US is not appropriate replacement
morphology of type 1
- resembles normal endo
- increased gland to stroma
- cribiform architecture
- nuclear atypia
what is grading in endo
amount of solid area
- more solid area is worse
what can be seen in E dependent before
precursor lesions
4 types of lesions
simple vs. complex
with or without atypia
complex with atypia has 50% risk
2 types of type 2
serous (papillary)
clear cell
- both are high grade
morpho of serous
- papillary archi
- high grade nuclear
- macro nuleai
morpho of clear cell
- clear cytoplasm
- high nuclear grade
- various architecture
precursors for serous and clear cell
serous - endometrial intraepitheliam carcinoma
clear cell - none
4 prognostic factors
- myoinvasion
- lymphovascular invasion
- cervical invasion
- mets
mgmt of edno CA
surgical
outcomes for 2 types
type 1 - usually found early and cured
type 2 - usually found late and poor
etiology of cerv. CA
HPV- most only dev. sublincal infection
3 cofactors
- smoking
- immunocompromise
- OCP
2 types of cerv. prevention
1ry - avoid HPV and cofactors
2ry - paps
2 types of 2ry prevention
- traditional - pap smear
- liquid based cytology medium
- less false neg
- increase sens
tips for collection
- before bimanual
- don’t contam. with lube
- collect before STD swabs
- ensure visualization
what are challenges in cerv. screening
- high false neg
- less reduction in adenocarcinoma
- is opportunitic - relies on pt and halthcare provider
when to start screen
21 - long time to dev SIL and LSIL is transient
how often
annual is standard practice, but if have negs, can do every 2-3 years because of sig. lead time
when to stop
consider stopping at 65-70 or hysterectomy with normal pap Hx
- continue if at risk
- continure in hyterectomy if HSIL in past
what to do with abnormal result
colposcopic eval
*** bethesda classification
satisfactory vs. unsat
neg vs. epithelial cell abnormal
2 types of abnormal
- squamous
- ASC (us or H)
- LSIL
- HSIL
- carcinoma - glandular
- AGC atypical glandular cells
- AGC favour neoplasia
- adenocarcinoma
what is only one that doesn’t need colposcopy
ASC-US
- up to 5%
option for ASC-US
- immed. colposcopy
- repeat smears q6mox3
- HPV DNA test
5 alternative causes for abnormal smears
- atrophic changes
- inflamm/infection
- regen after injury
- CA of other source
- previous radiation
what is pap test NOT
screening test, not a diagnostic test
4 types of squamous lesions
normal squam cell
LSIL
HSIL
SCC
** what is cytopathology
koilocyte - HPV infected cell
- enlarged nuc
- irreg nuc
- hyperchromasia
- binucleation
- cytopasmic halo
3 types of glandular leasion
normal endo glands
adenocarcinoma in situ
adenocarcinoma
