24
Q

Letrozole is?

A

Aromatase inhibitor,
reduces androgen conversion to estrogen,
stimulates follicular development for ovulatory induction

25
Q

gonadorelin is?

A

GnRH agonist, stimulates release of FSH/LH from pituitary

26
Q

Novarel is?

A

Human chorionic gonadotropin

Similar structure to LH, triggers ovulation after gonadotropin folliclestimulation

27
Q

metformin helps get pregnant via?

A

Insulin sensitizer, decreases insulin,testosterone, BMI; promotes ovulation

28
Q

Clomiphene citrate is

A

Anti-estrogen, stimulates follicular development for ovulation induction

29
Q

Day 3 labs are:

A

FSH and estradiol levels, AMH levels, and AFC

30
Q

Clomiphene citrate works via?

A
  • antiestrogen, binds to estrogen receptors in the hypothalamus–>
  • ↑ FSH and LH –>
  • follicular maturation and ovulation
31
Q

Clomiphene citrate is best used for?

A

women with chronic anovulation or mild hypothalamic insufficiency after specific causes of hypothalamic dysfunction have been ruled out.

32
Q

Human menopausal gonadotropins are used for?

A

a form of FSH, or FSH + LH

directly stimulate follicular maturation in patients for whom Clomid has failed,

33
Q

ovarian Hyper-stimulation syndrome

A

Very dangerous

fertility stuff–> ovarian enlargement, torsion, and rupture

34
Q

Risk factors for endometrial carcinoma include

A 
nulliparity
late menopause
 hypertension
 exposure to unopposed estrogens. 
*obesity confers the greatest risk of developing endometrial carcinoma,
35

Approximately 80-90% of women with endometrial carcinoma present with ?

A

vaginal bleeding or discharge as their only presenting symptom

36

Breast	28%
Lung	14%
Colon	10%
Uterine 6%
Ovary	3%
37
Q

Risk factors for endometrial cancer include

A 
late menopause
 unopposed estrogen therapy
 nulliparity
obesity
Tamoxifen therapy
diabetes mellitus.
38
Q

Unopposed estrogen replacement therapy does increase the risk of endometrial cancer, but not when?

A

taken in combination

39
Q

Routine eval for endometrial ca would include

A

chest x-ray- lungs most common site for mets

40
Q

The recommended components of the surgical approach to an early endometrial cancer are ?

A

extrafascial total abdominal hysterectomy
bilateral salpingo-oophorectomy

atrophy of the endometrium (60-80%)
hormone replacement therapy (15-25%)
 endometrial cancer (10-15%)
polyps (2-12%)
hyperplasia (5-10%).

Any history of vaginal bleeding requires assessment of the endometrium.

thickening
thus US does not help you eval if apt is getting CA from the drug
If they do get CA, likely to show symptoms
