29
Q

What causes Gestational Trophoblastic Disease?

A

Abnormal Proliferation of the Trophoblast: supplying the embryo with nourishment and later forming the major part of the placenta

30
Q

What are the three types of Gestational Trophoblastic Disease?

A
  • HYDATIFORM MOLE - benign trophoblastic disease
  • INVASIVE MOLE (CHORIOADENOMA DESTRUENS) - malignant nonmetastatic trophoblastic disease
  • CHORIOCARCINOMA - malignant metastatic trophoblastic disease
31
Q

True or False: 1 in 100 pregnancies in US and Europe result in Hydatiform Mole

A

False: 1 in 1000 pregnancies in US and Europe result in a Hydatiform Mole
The highest incidences are in Far East and Asia

32
Q

What are some of the Risk factors for Gestational Trophoblastic Disease?

A
  • AGE (OVER 40YEARS OR UNDER 20 YEARS)
  • PREVIOUS MOLAR PREGNANCY
  • BLOOD TYPE
  • BIRTH CONTROL PILLS
  • NUMBER OF SEXUAL PARTNERS
  • SOCIOECONOMIC
33
Q

What are the 2 types of Hydatiform Mole?

A

Complete and Incomplete

34
Q

What is a COMPLETE Hydatiform Mole?

A
  • Fertilization of defective ovum by single sperm that duplicates
  • Fertilization of one ovum by two sperm
  • Higher malignant potential
  • Hydropic degeneration and swelling of the chorionic villi
  • Proliferation of the trophoblast
  • Absence of fetus and amnion
35
Q

What is an INCOMPLETE Hydatiform Mole?

A
  • Fertilization of a normal egg by two sperm
  • Fertilization of a normal ovum by a sperm with a diploid set of chromosomes
  • Focal and less advanced hydatiform changes
  • Some villi spared and not others
  • Fetus, fetal parts, or amniotic sac rarely present
36
Q

A Theca Lutein Cysts is found in 20-30% of patients with what kind of pregnancy?

A

Molar Pregnancy

37
Q

What is a molar pregnancy?

A

Molar pregnancy is an abnormal form of pregnancy in which a non-viable fertilized egg implants in the uterus and will fail to come to term.

38
Q

What is the cause of Theca Lutein Cysts?

A

Elevated levels of Human chorionic gonadotropin (hCG)

39
Q

True or False: Theca Lutein Cysts are unilateral

A

False: They are Bilateral

Q

True or False: Theca Lutein Cysts are prone to hemorrhage

A

True

41
Q

How long after the evacuation of the uterus will a Theca Lutein Cyst remain?

A

2-4 Months

42
Q

What is Gestational trophoblastic disease (GTD)?

A

Gestational trophoblastic disease (GTD) is a group of pregnancy-related conditions that develop inside a woman’s uterus (womb). The abnormal cells start in the tissue that would normally become the placenta. The placenta is the organ that develops during pregnancy to feed the fetus.

A
  • IRREGULAR VAGINAL BLEEDING DURING PREGNANCY
  • DISCREPANT UTERINE HEIGHT
  • HYPEREMESIS

44
Q

Lab findings for Gestational trophoblastic disease (GTD)?

A

ELEVATED SERUM hCG
>100,000mIU/ml
Triple the normal level
Continue to rise 100 days after LMP

45
Q

US Findings in 1st trimester for Gestational trophoblastic disease (GTD)

A
  • Blighted ovum
  • Missed abortion
  • Degenerating leiomyoma
  • Hydropic placenta
  • Endometrial cancer
  • Adenomyosis
46
Q

US Findings in 2nd trimester for Gestational trophoblastic disease (GTD)

A
  • Soft tissue mass with sonolucent areas of different sizes
  • “snow flake or lacey pattern”
  • Absence of fetal parts
  • Myometrium may appear hypoechoic
  • Uterus large for dates
  • Bilateral theca lutein cysts may be present
47
Q

What is an invasive mole?

A

Invasive mole is a tumorous growth associated with gestation and falls under the spectrum of gestational trophoblastic disease

48
Q

Chorioadenoma Destruens is also known a?

A

Invasive Mole

49
Q

True or False: Invasive moles are Malignant non-metastatic trophoblastic diseases that are a progression of a benign disease

A

True

50
Q

What percentage do invasive moles occur?

A

15-18% of cases

51
Q

Invasive moles penetrate and invade what area?

A

the Myometrium

52
Q

If elevated levels of hCG are present, what is the suspected reason?

A

Invasive Mole

53

Ultrasound Appearance of an invasive mole

A 
Cannot distinguish from benign condition
Enlarged uterus
Cystic spaces of varying sizes 
Echogenic areas within uterus
Diagnosed after hysterectomy with examination of myometrium
54
Q

What is Choriocarcinoma?

A

Choriocarcinoma is a fast-growing cancer that occurs in a woman’s uterus (womb)

Malignant Metastatic Trophoblastic Disease

55
Q

What percentage of Hydatiform moles become choriocarcinoma?
