Q

What are sonohysterograms?

A

A technique in which fluid is injected through the cervix into the uterus, and ultrasound is used to make images of the uterine cavity. The fluid shows more detail of the inside of the uterus than when ultrasound is used alone

21
Q

What is the general management for endometrial hyperplasia if simple? Complex?

A

Simple = progesterone therapy

Complex = hysterectomy

22
Q

What endometrial tissue thickness is concerning for postmenopausal women?

A

More than 4 mm

23
Q

What is advanced imaging of the pelvis particularly indicated?

A

If there is evidence of endometrial cancer

24
Q

What are the treatments for endometrial cancer?

A

Total abdominal hysterectomy and removal of tubes + ovaries

25
Q

What is the medical treatment for endometrial cancer in the case of poor surgical candidates?

A

XRT or progesterone

26
Q

What are the routes through which endometrial cancer usually mets?

A

Local extension and lymphatics

Rare hematogenous spread

27
Q

What is the risk for endometrial cancer with postmenopausal bleeding?

A

20% ish

28
Q

What percent of endometrial cancers present with postmenopausal bleeding?

A

90%

29
Q

What, besides postmenopausal bleeding, are the s/sx of endometrial cancer?

A
  • Lower abdominal pain
  • Hematuria
  • Frequency
  • Rectal bleeding
  • hip or back pain
30
Q

What are the three modalities for assessing abnormal uterine bleeding?

A
  • Endometrial bx
  • US (saline sonohysterogram)
  • Hysteroscopy D&C
31
Q

What are the four aspects of pretreatment eval for endometrial CA?

A
  • PE
  • Endometrial sampling
  • Blood work
  • CXR
32
Q

What are the two most critical factors for the prognosis of endometrial cancer?

A

Grade and histology

33
Q

What is the 2nd most critical prognostic factor of endometrial CA?

A

Depth of myometrial invasion

34
Q

What are the important surgical prognostic factors?

A

Histological type

35
Q

What is the treatment failure of papillary adenoCA?

A

32%

36
Q

What is the treatment failure of serous papillary adenoCA?

A

63%

37
Q

What is the importance of depth of myometrial spread with uterine cancer?

A

Risk of lymph node spread, treatment failure, and death from disease

38
Q

How common are uterine sarcomas?

A

Less than 5% of uterine malignancies

39
Q

Sarcomas usually arise from what type of tissue?

A

Muscles

40
Q

What are uterine sarcomas?

A

Tumors arising from myometrium or stromal components

41
Q

What is the prognosis for uterine sarcomas?

A

Bad

42
Q

How common is fallopian tube cancer?

A

Super Rare (0.41/100,000)

43
Q

What are the primary risk factors for fallopian tube cancer? Associated risk factors?

A
  • BRCA1 and BRCA2

- Infertility and low parity

44
Q

Fallopian tube cancers are mostly of what type?

A

Adenocarcinomas

45
Q

What is hydrops tubae profluens?

A

Intermittent expulsion of clear or serosanguinous fluid from the vagina

46
Q

What is Latzko’s triad?

A

S/sx of tubal CA:

  • Intermittent serosanguineous d/c
  • Colicky pain
  • Mass
47
Q

Why is there an increased risk of endometrial cancer with PCOS?

A

Less frequent ovulation means that there is an increase in estrogen exposure

48
Q

How does birth control decrease the risk of endometrial cancer?

A

Lower estrogen amount, and increase progesterone
