Definition
 Gestational trophoblastic disease (GTD) refers to a spectrum
of interrelated but histologically distinct tumors originating
from the placenta.
 Characterized by a reliable tumor marker, which is the β-
subunit of human chorionic gonadotropin (β-hCG).

3
 Gestational trophoblastic neoplasia (GTN)
refers to the subset of GTD that develops malignant sequelae.
These tumors require normal staging and typically respond
favorably to chemotherapy. Most commonly, GTN develops
after a molar pregnancy but may follow any gestation

6
• It is a benign neoplasm of the chorionic villi.
• Incidence:
1:2000 pregnancies in United States and Europe, but
10 times more in Asia. The incidence is higher
toward the beginning and more toward the end of
the childbearing period. It is 10 times more in
women over 45 years old.

• The uterus is distended by thin walled,
translucent, grape-like vesicles of different
sizes. These are degenerated chorionic villi
filled with fluid.
• There is no vasculature in the chorionic villi
leads to early death and absorption of the
embryo.

Hydatidiform :mole
Hyperplasia of trophobasitc cells • Hydropic
swelling of all villi • Vessles are usually absent

9
Pathology
 There is trophoblastic proliferation, with mitotic activity affecting
both syncytial and cytotrophoblastic layers. This causes excessive
secretion of hCG, chorionic thyrotrophin and progesterone. On
the other hand, oestrogen production is low due to absence of
the foetal supply of precursors.

Pathology
High hCG causes multiple theca lutein cysts in
the ovaries in about 50% of cases.
Cysts may reach a large size
10 cm or more.

• Cysts disappear
within few months(2-3),
after evacuation of the mole.

• High hCG causes multiple theca lutein cysts in
the ovaries in about 50% of cases. It also
results in exaggeration of the normal early
pregnancy symptoms and signs.

 Partial moles are optimally diagnosed when
three or our major diagnostic criteria are
demonstrated:
 (1) two populations o villi,
 (2) enlarged, irregular, dysmorphic villi (with
trophoblast inclusions),
 (3) enlarged, cavitated villi (≥ 3 to 4 mm), and
 (4) syncytiotrophoblast hyperplasia/atypia

DIAGNOSIS
5/13/2021
med-trainings.com
21
Symptoms
•Amenorrhoea: usually of short period (2-3 months).
•Exaggerated symptoms of pregnancy especially
vomiting.
•Vaginal discharge
•Abdominal pain: may be,
o dull-aching due to rapid distension of the uterus, o
colicky due to starting expulsion,
o sudden and severe due to perforating mole.
Discharge
The main complaint, due to separation of vesicles from
uterine wall, there may be a blood stained watery
discharge, the watery part is from ruptured vesicles.
Prune juice disharge may occur.
The blood is brown because it has retained for
sometime in the uterine cavity.
passage of vesicles is diagnostic. The blood may be
concealed causing enlargement & tenderness of
uterus.

22
Abdominal pain : may be
- dull-aching due to rapid distension of the
uterus by the mole or by concealed haemorrhage.
- Colicky due to starting expulsion,
- Sudden And Severe due to perforating mole
- Ovarian pain due to stretching of the ovarian
capsule or complication in the cystic ovary as
torsion

23
Pre-eclampsia in 20-30% of cases, usually before 20 weeks’ gestation.
Pallor indicating anemia may be present.
Hyperthyroidism in 3-10% of cases manifested by enlarged thyroid gland,
tachycardia (due to chorionic thyrotropin secreted by trophoplast &HCG
also has a thyroid stimulating effect.
Breast signs of pregnancy
5/13/2021
med-trainings.com
24
Signs
Abdominal examination:
• The uterus is larger than the period of
amenorrhoea in50% of cases, corresponds to
it in 25% and smaller in 25% with inactive or
dead mole.
• The uterus is doughy in consistency
• Foetal parts and heart sound cannot be
detected except in partial mole.
5/13/2021

25
Signs
* Local examination:
> Passage of vesicles (sure sign).
>Bilateral ovarian cysts (5-20 cm) in
50%
of cases.

Investigations
5/13/2021
med-trainings.com
27
Urine pregnancy test: is positive in high dilution. 1/200 is
highly suggestive, 1/500 is surely diagnostic. In normal
pregnancy it is positive in dilutions up to 1/100.
Serum β-hCG level: is highly elevated (>100000 mIU/ml).
* Ultrasonography reveals:
o The characteristic intrauterine "snow storm"
appearance,
o no identifiable foetus,
o bilateral ovarian cysts may be detected.
X-ray: shows no foetal skeleton.
Partial Mole: Complex mass with many
cystic areas (between arrowheads) and
an embryo (arrow) in a patient with a β-
HCG of 280,000 miu/ml

Complications
5/13/2021
med-trainings.com
31
• Haemorrhage.
• Infection due to absence of the amniotic sac.
• Perforation of the uterus.
• Pregnancy induced hypertension
• Hyperthyroidism.
• Subsequent development of
choriocarcinoma
Treatment
5/13/2021
med-trainings.com
32
• As soon as the diagnosis of vesicular mole is
established the uterus should be evacuated.
• The selected method depends on the size of
the uterus, whether partial expulsion has
already occur or not, the patient's age and
fertility desire.
• Cross- matched blood should be available
before starting.
Points to note
Nulliparous women are not given
prostanoids to ripen the cervix since these
drugs can induce uterine contractions and
might increase the risk of trophoblastic
embolization to the pulmonary vasculature.
Because o the tremendous vascularity of
these placentas, blood products should be
available prior to the evacuation, and
adequate infusion lines established.
5/13/2021

33
Suction evacuation
5/13/2021
med-trainings.com
34
It is carried out under GA.
An infusion of 20 units oxytocin in 500 m1 of 5% glucose
should be maintained throughout the procedure.
Dilatation of the cervix is done up to a Hegar's number
equal to the period of amenorrhoea in weeks e.g. No.
10 Hegar for 10 weeks’ amenorrhoea. The suction
canula used will be of the same size also.
Suction evacuation
contd…
• A suction canula which may be metal or a disposable plastic
preferred) is introduced into the uterine cavity
• The canula is connected to a suction pump adjusted at negative
pressure of 300-500 mmHg according to the duration of
pregnancy.
• Although some recommended a gentle sharp curettage to the
uterus after evacuation, it is preferable to wait one week for fear
of uterine perforation.
• Following curettage, because o the possibility o partial mole and
its attendant fetal tissue, Rh immune globulin is given to
nonsensitized Rh D-negative women.

35
Hysterotomy
5/13/2021
med-trainings.com
36
• It may be needed for evacuation of a large
mole to minimise and facilitate control of
bleeding.
Hysterectomy:It should be considered in
women over 40 years who have completed
their family for fear of developing
choriocarcinoma.

37
• As choriocarcinoma may complicate the
vesicular mole after its evacuation,
detection of serum ß-hCG by
radioimmunoassay for 2 years is essential.
• About 3-5% of H.Mole develop
choriocarcinoma & 15-20% become locally
invasive.

5/13/2021

38
• Detection is done every:
hCG levels: obtained within 48 hrs of
evacuation,
Weekly until not detectable for three
consecutive weeks.
Monthly till 6-12 months( partial or comp)
Risk of GTN is <1% after an undectable hCG is
attained.

• Pelvic Ultrasound:
• Performed with hCG values to monitor
involution of pelvic structures and identify
persistent disease.

• Reliable contraception:
• Hormonal or Barrier recommended.
• IUCD has risk of perforation X.
• A new gestation should be avoided because it
will obscure value of monitoring hCG levels.
• If hCG remains undectable for 6-12 months
woman desirous of pregnancy may
discontinue contraception
GTD: 5, Studd Current Progress in Obst & Gyne, 2019
• Persistent high level indicates remnants of
molar tissues which necessitate
chemotherapy (methotrexate) with or
without curettage. Hysterectomy is indicated
if women had enough children.
5/13/2021
med-trainings.com
41
• Rising hCG, level after disappearance means
developing of choriocarcinoma or a new pregnancy.
So combined contraceptive pills should be used for
prevention of pregnancy which can be misleading.
• It is expected that urine pregnancy test is negative 4
weeks after evacuation and serum β-hCG is
undetectable 4 months after evacuation.
* Early features suggesting residual molar tissue include:
o recurrent or persistent vaginal bleeding, o
amenorrhoea,
o failure of uterine involution,
o persistence of ovarian enlargement.
5/13/2021

42
Persistent GTD
 After evacuation of complete or partial mole hCG
levels show a plateau or rise over several weeks(days
1,7,14,21) more than 4 values in 3 weeks
 Rise in serum hCG >10% during these weeks
 Serum hCG remains detectable for 6 months or more
 Histological of chorioarcinoma or invasive mole
 Identification of clinical or radiological metastasis.

  • 9. Hydatidiform :mole Hyperplasia of trophobasitc cells • Hydropic swelling of all villi • Vessles are usually absent 5/13/2021 med-trainings.com 9
  • 10. Pathology  There is trophoblastic proliferation, with mitotic activity affecting both syncytial and cytotrophoblastic layers. This causes excessive secretion of hCG, chorionic thyrotrophin and progesterone. On the other hand, oestrogen production is low due to absence of the foetal supply of precursors. 5/13/2021 med-trainings.com 10
  • 11. Pathology High hCG causes multiple theca lutein cysts in the ovaries in about 50% of cases. Cysts may reach a large size 10 cm or more. 5/13/2021 med-trainings.com 11 • Cysts disappear within few months(2-3), after evacuation of the mole.
  • 12. Pathology 5/13/2021 med-trainings.com 12 • High hCG causes multiple theca lutein cysts in the ovaries in about 50% of cases. It also results in exaggeration of the normal early pregnancy symptoms and signs.
  • 15. Partial mole 5/13/2021 med-trainings.com 15 - A part of trophoblastic tissue only shows molar changes. - There is a foetus or at least an amniotic sac. - It is the result of fertilization of an ovum by 2 sperms so the chromosomal numberis 69 chromosomes

  • 21. DIAGNOSIS 5/13/2021 med-trainings.com 21 Symptoms •Amenorrhoea: usually of short period (2-3 months). •Exaggerated symptoms of pregnancy especially vomiting. •Vaginal discharge •Abdominal pain: may be, o dull-aching due to rapid distension of the uterus, o colicky due to starting expulsion, o sudden and severe due to perforating mole.
  • 22. Discharge The main complaint, due to separation of vesicles from uterine wall, there may be a blood stained watery discharge, the watery part is from ruptured vesicles. Prune juice disharge may occur. The blood is brown because it has retained for sometime in the uterine cavity. passage of vesicles is diagnostic. The blood may be concealed causing enlargement & tenderness of uterus. 5/13/2021 med-trainings.com 22
  • 23. Abdominal pain : may be - dull-aching due to rapid distension of the uterus by the mole or by concealed haemorrhage. - Colicky due to starting expulsion, - Sudden And Severe due to perforating mole - Ovarian pain due to stretching of the ovarian capsule or complication in the cystic ovary as torsion 5/13/2021 med-trainings.com 23
  • 24. Pre-eclampsia in 20-30% of cases, usually before 20 weeks’ gestation. Pallor indicating anemia may be present. Hyperthyroidism in 3-10% of cases manifested by enlarged thyroid gland, tachycardia (due to chorionic thyrotropin secreted by trophoplast &HCG also has a thyroid stimulating effect. Breast signs of pregnancy 5/13/2021 med-trainings.com 24
  • 25. Signs Abdominal examination: • The uterus is larger than the period of amenorrhoea in50% of cases, corresponds to it in 25% and smaller in 25% with inactive or dead mole. • The uterus is doughy in consistency • Foetal parts and heart sound cannot be detected except in partial mole. 5/13/2021 med-trainings.com 25
  • 26. Signs * Local examination: > Passage of vesicles (sure sign). >Bilateral ovarian cysts (5-20 cm) in 50% of cases. 5/13/2021 med-trainings.com 26
  • 27. Investigations 5/13/2021 med-trainings.com 27 Urine pregnancy test: is positive in high dilution. 1/200 is highly suggestive, 1/500 is surely diagnostic. In normal pregnancy it is positive in dilutions up to 1/100. Serum β-hCG level: is highly elevated (>100000 mIU/ml). * Ultrasonography reveals: o The characteristic intrauterine "snow storm" appearance, o no identifiable foetus, o bilateral ovarian cysts may be detected. X-ray: shows no foetal skeleton.
  • 28. Partial Mole: Complex mass with many cystic areas (between arrowheads) and an embryo (arrow) in a patient with a β- HCG of 280,000 miu/ml 5/13/2021 med-trainings.com 28

  • 31. Complications 5/13/2021 med-trainings.com 31 • Haemorrhage. • Infection due to absence of the amniotic sac. • Perforation of the uterus. • Pregnancy induced hypertension • Hyperthyroidism. • Subsequent development of choriocarcinoma
  • 32. Treatment 5/13/2021 med-trainings.com 32 • As soon as the diagnosis of vesicular mole is established the uterus should be evacuated. • The selected method depends on the size of the uterus, whether partial expulsion has already occur or not, the patient's age and fertility desire. • Cross- matched blood should be available before starting.
  • 33. Points to note Nulliparous women are not given prostanoids to ripen the cervix since these drugs can induce uterine contractions and might increase the risk of trophoblastic embolization to the pulmonary vasculature. Because o the tremendous vascularity of these placentas, blood products should be available prior to the evacuation, and adequate infusion lines established. 5/13/2021 med-trainings.com 33
  • 34. Suction evacuation 5/13/2021 med-trainings.com 34 It is carried out under GA. An infusion of 20 units oxytocin in 500 m1 of 5% glucose should be maintained throughout the procedure. Dilatation of the cervix is done up to a Hegar's number equal to the period of amenorrhoea in weeks e.g. No. 10 Hegar for 10 weeks’ amenorrhoea. The suction canula used will be of the same size also.
  • 35. Suction evacuation contd… • A suction canula which may be metal or a disposable plastic preferred) is introduced into the uterine cavity • The canula is connected to a suction pump adjusted at negative pressure of 300-500 mmHg according to the duration of pregnancy. • Although some recommended a gentle sharp curettage to the uterus after evacuation, it is preferable to wait one week for fear of uterine perforation. • Following curettage, because o the possibility o partial mole and its attendant fetal tissue, Rh immune globulin is given to nonsensitized Rh D-negative women. 5/13/2021 med-trainings.com 35
  • 36. Hysterotomy 5/13/2021 med-trainings.com 36 • It may be needed for evacuation of a large mole to minimise and facilitate control of bleeding. Hysterectomy:It should be considered in women over 40 years who have completed their family for fear of developing choriocarcinoma.
  • 37. Follow up 5/13/2021 med-trainings.com 37 • As choriocarcinoma may complicate the vesicular mole after its evacuation, detection of serum ß-hCG by radioimmunoassay for 2 years is essential. • About 3-5% of H.Mole develop choriocarcinoma & 15-20% become locally invasive.
  • 38. Follow up 5/13/2021 med-trainings.com 38 • Detection is done every: hCG levels: obtained within 48 hrs of evacuation, Weekly until not detectable for three consecutive weeks. Monthly till 6-12 months( partial or comp) Risk of GTN is <1% after an undectable hCG is attained. GTD: 5, Studd Current Progress in Obst & Gyne, 2019
  • 39. Follow up 5/13/2021 med-trainings.com 39 • Pelvic Ultrasound: • Performed with hCG values to monitor involution of pelvic structures and identify persistent disease. GTD: 5, Studd Current Progress in Obst & Gyne, 2019
  • 40. Follow up 5/13/2021 med-trainings.com 40 • Reliable contraception: • Hormonal or Barrier recommended. • IUCD has risk of perforation X. • A new gestation should be avoided because it will obscure value of monitoring hCG levels. • If hCG remains undectable for 6-12 months woman desirous of pregnancy may discontinue contraception GTD: 5, Studd Current Progress in Obst & Gyne, 2019
  • 41. • Persistent high level indicates remnants of molar tissues which necessitate chemotherapy (methotrexate) with or without curettage. Hysterectomy is indicated if women had enough children. 5/13/2021 med-trainings.com 41
  • 42. • Rising hCG, level after disappearance means developing of choriocarcinoma or a new pregnancy. So combined contraceptive pills should be used for prevention of pregnancy which can be misleading. • It is expected that urine pregnancy test is negative 4 weeks after evacuation and serum β-hCG is undetectable 4 months after evacuation. * Early features suggesting residual molar tissue include: o recurrent or persistent vaginal bleeding, o amenorrhoea, o failure of uterine involution, o persistence of ovarian enlargement. 5/13/2021 med-trainings.com 42
  • 43. Persistent GTD  After evacuation of complete or partial mole hCG levels show a plateau or rise over several weeks(days 1,7,14,21) more than 4 values in 3 weeks  Rise in serum hCG >10% during these weeks  Serum hCG remains detectable for 6 months or more  Histological of chorioarcinoma or invasive mole  Identification of clinical or radiological metastasis. 5/13/2021 med-trainings.com 43
