Carcinoma of Uterus and Ovaries - Tieman Flashcards
leiomyoma regression
stimulated by estrogen
-so post-menopausal women - regresses
ovary gonadostromal tumor
produce estrogen
-so get endometrial hyperplasia**
most common female genital tract malignancy
uterine carcinoma
abnormal vaginal bleeding in perimenopausal/postmenopausal women
uterine carcinoma
risk fx for uterine carcinoma
obesity unopposed estrogen stimulation - permarin tamixifen nulliparity diabetes late menopause PCOS lynch syndrome
ovarian carcinoma
most LETHAL
because presents late
obesity
increased estrogen - fat cells secrete androstenedione - converted to estrogen
decreased risk of uterine carcinoma
ovulation progestin therapy combo BCPs** eraly menopause multiparity
complex atypical hyperplasia
not cancer - but 8x increased risk
recommend TAH-BSO
endometrial carcinoma staging
done surgically**
stage 1a endometrial carcinoma
confined to endometrium
stage 1b endometrial carcinoma
invasion to <1/2 myometrium
stage 1c endometrial carcinoma
invasion to >1/2 myometrium
stage 2 endometrial carcinoma
invades endocervical canal
stage 3 endometrial carcinoma
tumor in peritoneum, vagina, nodes
stage 4 endometrial carcinoma
distant mets
evaluation of abnormal vaginal bleeding
pelvic exam/pap smear
endometrial sampling
transvaginal U/S
fractional D and C
endometrial stripe
should be <5mm
favorable histo of endometrial carcinoma
endometroid
grade
differentation
lymph drainage of endometrial cancer
iliac/para-aortic nodes
stage 1, grade 1 and 2 endometrial cancer
TAH-BSO
peritoneal washings
removal enlarged nodes
stage 1c or 2, grade 3 endometrial cancer
TAH-BSO
cytology
iliac/paraaortic node dissection - with radiation
stage 3 and 4 endometrial cancer
surgical debulking
radiation
chemotherapy
remove everything that looks bad - to make chemo/rad work better
fractional D and C
to see if cancer to endocervical canal
stage 1 vs. 2
increased risk of ovarian carcinoma
white nulliparity/infertile late childbearing late menopause fam hx BRCA**
decresed risk of ovarian carcinoma
ovulation interrupted
oral contraceptives multiparity breast feeding tubal ligation hysterectomy
most lethal cancer female genital tract
ovarian
due to late stage of disease at diagnosis
increasing girth, pelvic fullness, pelvic discomfort
most patient - stage 3 or 4 age 50-70yo
ovarian cancer screening
non proven to be effective
beta-HCG
choriocarcinoma
AFP
dermoid ovarian cancer
CA125 and 19-9
epithelial derived
most ovarian cancers
majority serous epithelium
B9 and low grade - not removed - young women who still want children
ovarian cancer spread
internal iliac, common iliac, paraaortic nodes
germ cell tumors
dysgerminomas and teratomas
granulosa thecal cell tumor
secrete E/PR
sertoli-leydig cell tumor
secrete androgens
ovarian cancer staging
done surgically
stage 1 ovarian cancer
confined to ovary
stage 2 ovarian cancer
tumor spread confined to pelvis
stage 3 ovarian cancer
confined to abdominal peritoneal surfaces or retroperitoneal nodes
stage 4 ovarian cancer
distant mets
optimal cytorecuduction
get rid of every part of tumor
ovarian cancer treatment
radiation or platinum based chemotherapy dependent upon stage, histology, and grade of tumor
stage 1 low grade ovarian cancer tx
no further tx
stage 1 high grade ovarian cancer tx
platinum based chemo - paclitaxel
germ cell tumor of ovary tx
platinum based chemo, blemycin, etoposide
gonadal-stromal tumors of ovary
relatively chemoresistant
most important aspect of tx for long term prognosis of ovarian cancer
excision of any visible tumor
bowel prep
mandatory for ovarian ca surgery
bc may be location of spread - and may need to take it
