(31 cards)
endometrial hyperplasia
endometrial gland proliferation (precursor to endometrial carcinoma)
*due to unopposed estrogen w/o progesterone
common cuases of endom. hyperplasia
chronic anovulation, PCOS, perimenopause, obesity (conversion of androgen to estrogen in adipose tissue)
how soon after does hyperplasia occur with estrogen only treatment?
3 yrs
what time of life do most women get hyperplasia?
after menopause
s/sx of hyperplasia?
bleeding–> menorrhagia, metorrhagia, postmenopausal bleeding
+/- vag d/c
dx of hyperplasia
transvaginal US : endometrial stripe > 4mm *screening
what is the definitive dx for hyperplasia?
endometrial bx
indications for an endometrial bx?
> 35 yrs, ↑endometrial stripe seen on TVUS, patients on unopposed estrogen tx, Tamoxifen, AGS on Pap smear or persistent bleeding w/endometrial stripe >4mm
tx of endometrial hyperplasia w/o atypia
Progestin (PO or IUD Mirena) → Stops estrogen from being unopposed, limiting endometrial growth
Repeat endometrial bx in 3-6 mos
tx of endometrial hyperplasia w/ atypia
hysterectomy, but can just use progesterone
endometiral cancer
mos common gyn malignancy in US
*MC in postmenopausal
RF for endo CA
↑Estrogen Exposure, nulliparity, chronic anovulation, PCOS, obesity, estrogen replacement therapy, late menopause, Tamoxifen (estrogen stimulates endometrial growth), HTN, diabetes
OCPs and ovarian /endometrial cancers
protective againse
s/sx of endo ca
abnormal uterine bleeding, postmenopausal bleed
menorrhagia or metrorrhagia
what is metrorrhagia?
bleeding that occurs btw periods
dx of edno CA
biopsy
US: endometrial strip > 4mm –> may r/o other causes of bleeding
what ist the MC endo CA?
adenocarcinoma, then sarcoma
how is stage I endo CA tx?
hysterectomy, post-op radiation
*one of the most curable of gyn cancers
stage 2/3 tx
TAH-BSO + lymph node escision
Stage IV
systmeic chemo
endometriosis
Presence of endometrial tissue (stroma & gland) outside the endometrial (uterine) cavity
