Q

important findings in pelvic exam

A
  • check rectovaginal portion (posterior cul de sac)

17
Q

washings needed for staging

A
  • diaphragm
  • right and left hemiabdomen
  • pelvis even if there is tumor rupture or tumor on external capsule
  • ascites or abdominal cavity
18
Q

t/f you need to remove primary ovarian / fallopian tube tumor with intact capsule

A

true, with thbso

infracolic omentectomy. infragastric omentectomy for gross omental involvement

19
Q

2 samples of random biopsy from

A
  • undersurface of right hemidiaphragm
  • bladder reflection
  • cul de sac
  • r and l paracolic recesses
  • r and l pelvic side walls
20
Q

what is systematic lymphadenectomy

A

complete pelvic ln dissection and paraaortic ln sampling

appendectomy also possible

21
Q

stage I ovarian ca

A
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
22
Q

stage II ovarian ca

A
IIa = extension on uterus and/or fallopian tubes and/or ovaries
IIb = extension to other pelvic intraperitoneal tissues
23
Q

stage III ovarian ca

A

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

24
Q

stage IV ovarian ca

A

IVa pleural effusion with (+) cytology

IVb parenchymal metastases and metastases to extraabdominal organs

25
Q

most frequent epithelial ovarian tumors

A

serous, mucinous, endometrioid, clear cell

26
Q

management for epithelial ovarian tumros

A

adjuvant chemo, paclitaxel-carboplatin

27
Q

most common ovarian epithelial tumor

A

serous cystadenocarcinoma (resembles fallopian tube e)

risk: reproductive, >40 yo

28
Q

classic triad for fallopian tube ca

A
  • clear or blood tinged vaginal discharge (hydrops tubae profluens)
  • pelvic pain
  • pelvic mass
29
Q

type of surgery for all ovarian/ fallopian/ peritoneal tumors

A

cytoreductive = want to get zero residual

30
Q

what is mucinous cystadenocarcinoma

A
  • mucin filled
  • risk: reproductive, 30-60
  • resemble endocervical or intestinal e.
31
Q

what is endometrioid ca

A
  • risk: peri or postmenopausal with low parity

- associated with endometriosis

32
Q

what is clear cell ca

A
  • less common, more aggressive
  • risk: 40-70 yo
  • identical histo with endometrium, cervix, vaginal tumors
  • hobnail cells w/ nucleus standing on stalk of cytoplasm
33
Q

second most frequent ovarian neoplasm

A

germ cell tumors

34
Q

what are germ cell tumors

A
  • risk: young (<30 yo)

- have homologous counterparts in males

35
Q

diagnosis for germ cell tumors

A
  • tumor markers

- frozen section

36
Q

management for germ cell tumors

A
  • remove ovary, stage
  • leave uterus and contra ovary (sensitive to chemo)
  • adjuvant: multiagent chemo
37
Q

most common malignant germ cell tumor

A

dysgerminoma

  • tumor marker: ldh
  • analogous to seminoma in males
38
Q

second most common malignant germ cell tumor

A

immature teratoma

  • tumor marker: afr
  • resemble benign dermoid cyst
39
Q

what is endodermal sinus tumor

A
  • yolk sac tumor

- tumor marker afp

40
Q

most common sex cord stromal tumor

A

granulosa cell tumor

  • estrogen producing
  • seen in extremes of age
  • tumor marker: inhibin
41
Q

rare sex cord stromal tumor

A

sertoli leydig cell tumor (androblastoma)

  • virilizing tumor
  • indolent
42
Q

what is metastatic ovarian tumor (krukenberg tumor)

A
  • usually bilateral and solid
  • signet ring adenoca
  • tx: remove tumor and manage primary site
  • poor prognosis
