Surgery Ovary Flashcards
causes of pelvic mass by frequency and age group
read
when to suspect malignancy
pelvic or adnexal mass in extreme of age
prepubertal vs postmenopausal masses
prepubertal: functional cyst, gem cell tumor
postmenopausal: epithelial ovarian tumor
clinical presentation of pelvic mass
vague fullness, pressure, early satiety, flatulence
late: increasing abdominal girth, pain, mass, bleeding
abdominal enlargement happens when ovary is ___
10-15 cm
___ has the greatest influence in evaluation of pelvic mass
age, neoplasms more prevalent in older women
important findings in pelvic exam
- check rectovaginal portion (posterior cul de sac)
- firm nodularity in posterior cul de sac = further evaluation
- benign: cystic and movable
- malignant: solid and fixed
pertinent lab exams
all premenopausal: pregnancy test and cbc
ca 25 + he4
what is ca 125
- tumor marker for epithelial ovarian tumors
- n: <35 u/ml
- not effective screening tool
tumor markers
epithelial ovarian ca = ca 125 mucinous cystadenoca = ca 125, ca 19-9 mixed germ cell tumor, chorioca = bhcg granulosa cell tumor = inhibin yolk sac tumor = afp dysgerminoma = ldh
diagnostic test of choice for evaluating pelvic mass
uts
characteristics of ovarian mass
solid areas, thickened capsule, adhesions, size and composition, laterality
excellent modality for retroperitoneal masses
ct scan
central pathogenesis in ovarian ca
incessant ovulation
risk factors and protective factors for ovarian ca
risk: age, fhx, late menopause, nulliparity, late childbearing
protective: ocp, breastfeeding, tubal ligation
t/f ovarian ca is staged with ct scan
false, surgically with histopath confirmation
washings needed for staging
- diaphragm
- right and left hemiabdomen
- pelvis even if there is tumor rupture or tumor on external capsule
- ascites or abdominal cavity
t/f you need to remove primary ovarian / fallopian tube tumor with intact capsule
true, with thbso
infracolic omentectomy. infragastric omentectomy for gross omental involvement
2 samples of random biopsy from
- undersurface of right hemidiaphragm
- bladder reflection
- cul de sac
- r and l paracolic recesses
- r and l pelvic side walls
what is systematic lymphadenectomy
complete pelvic ln dissection and paraaortic ln sampling
appendectomy also possible
stage I ovarian ca
Ia = 1 ovary or fallopain tube 1b = both ovaries of fallopian tube 1c1 = surgical spill 1c2 = capsule ruptured before surgery or tumor on ovarian/f tube surface 1c3 = malignant cells in ascites or peritoneal washings
stage II ovarian ca
IIa = extension on uterus and/or fallopian tubes and/or ovaries IIb = extension to other pelvic intraperitoneal tissues
stage III ovarian ca
IIIa1 = microscopic positive retroperitoneal ln only
IIIa2 - microscopic extrapelvic peritoneal involvement +/- retroperitoneal
IIIb = macroscopic peritoneal metastasis beyong pelvis up to 2 cm - metastasis to retro ln
IIIc = macroscopic peritoneal metastasis beyond pelvis >2 cm
stage IV ovarian ca
IVa pleural effusion with (+) cytology
IVb parenchymal metastases and metastases to extraabdominal organs
most frequent epithelial ovarian tumors
serous, mucinous, endometrioid, clear cell
management for epithelial ovarian tumros
adjuvant chemo, paclitaxel-carboplatin
most common ovarian epithelial tumor
serous cystadenocarcinoma (resembles fallopian tube e)
risk: reproductive, >40 yo
classic triad for fallopian tube ca
- clear or blood tinged vaginal discharge (hydrops tubae profluens)
- pelvic pain
- pelvic mass
type of surgery for all ovarian/ fallopian/ peritoneal tumors
cytoreductive = want to get zero residual
what is mucinous cystadenocarcinoma
- mucin filled
- risk: reproductive, 30-60
- resemble endocervical or intestinal e.
what is endometrioid ca
- risk: peri or postmenopausal with low parity
- associated with endometriosis
what is clear cell ca
- less common, more aggressive
- risk: 40-70 yo
- identical histo with endometrium, cervix, vaginal tumors
- hobnail cells w/ nucleus standing on stalk of cytoplasm
second most frequent ovarian neoplasm
germ cell tumors
what are germ cell tumors
- risk: young (<30 yo)
- have homologous counterparts in males
diagnosis for germ cell tumors
- tumor markers
- frozen section
management for germ cell tumors
- remove ovary, stage
- leave uterus and contra ovary (sensitive to chemo)
- adjuvant: multiagent chemo
most common malignant germ cell tumor
dysgerminoma
- tumor marker: ldh
- analogous to seminoma in males
second most common malignant germ cell tumor
immature teratoma
- tumor marker: afr
- resemble benign dermoid cyst
what is endodermal sinus tumor
- yolk sac tumor
- tumor marker afp
most common sex cord stromal tumor
granulosa cell tumor
- estrogen producing
- seen in extremes of age
- tumor marker: inhibin
rare sex cord stromal tumor
sertoli leydig cell tumor (androblastoma)
- virilizing tumor
- indolent
what is metastatic ovarian tumor (krukenberg tumor)
- usually bilateral and solid
- signet ring adenoca
- tx: remove tumor and manage primary site
- poor prognosis
