Study Notes
Molar Pregnancies
- A molar pregnancy is a type of abnormal pregnancy characterized by rapid growth of nonviable tissue.
- Histologically, a molar pregnancy is composed of abnormal placental villi with numerous trophoblast cells forming chorionic vesicles filled with blood or blood clots.
- There are two types of molar pregnancies: complete hydatidiform mole and partial hydatidiform mole.
Complete Hydatidiform Mole
- All placental villi are abnormal, and the conceptus is absent or malformed.
- Placental tissue becomes enlarged and partially or entirely replaced by edematous vesicles with little or no villous tissue.
Partial Hydatidiform Mole
- Placental villi are partly abnormal, and the fetus is either normal or malformed.
Diagnosis and Treatment
- Histological examination of the placental tissue can confirm the presence of a molar pregnancy.
- In a complete hydatidiform mole, the placental villi are replaced by cystic vesicles containing chorionic vesicles filled with blood or blood clots.
- Suction curettage is the preferred method of evacuation, especially for those who want to preserve fertility.
- Rhesus-negative patients should receive rhesus immunoglobulin at the time of evacuation.
Risks and Complications
- Women over 40 years old have a 10 times higher risk of developing a molar pregnancy.
- Adolescent girls and women between 36-40 years old have a 2 times higher risk.
- Molar pregnancies can lead to gestational trophoblastic neoplasia (GTN), which is a type of cancer that occurs in the uterus.
- GTN can spread to other parts of the body, such as the lungs, liver, and brain.
Gestational Trophoblastic Neoplasia (GTN)
- GTN can occur after any type of pregnancy, not just molar pregnancies.
- Symptoms of GTN include abnormal vaginal bleeding, seizures, headaches, and hemoptysis.
- Diagnosis of GTN is based on a plateau or increase in hCG levels, vaginal bleeding, and histological examination.
- Treatment of GTN includes chemotherapy, surgery, and radiation therapy.
Choriocarcinoma
- Choriocarcinoma is a type of GTN that originates from the placenta.
- It can occur after any type of pregnancy, not just molar pregnancies.
- Symptoms of choriocarcinoma include abnormal vaginal bleeding, seizures, headaches, and hemoptysis.
- Diagnosis of choriocarcinoma is based on histological examination and high levels of hCG.
- Treatment of choriocarcinoma includes chemotherapy and surgery.### Imaging in Gestational Trophoblastic Neoplasia
- Doppler ultrasound examination is used to visualize a complete hydatidiform mole with a vascular uterine mass.
- Chest radiography is essential to detect pulmonary metastases, which are the most common type of metastasis.
- Brain MRI is recommended to exclude haemorrhagic metastases, especially in patients with seizures.
Treatment Resistance and Staging
- The FIGO prognostic scoring and anatomical staging systems are used to predict the potential for development of resistance to monochemotherapy with methotrexate or dactinomycin.
- The combined prognostic score helps identify patients who are at risk of treatment resistance.
- The FIGO system has been used since 2002 to allow comparison of data between physicians treating gestational trophoblastic neoplasia.
Radiographic Imaging
- Chest CT is not necessary when chest radiography findings are normal, as discovery of micrometastases does not affect outcome.
- If lesions are noted on chest radiograph, brain MRI and body CT are recommended to exclude more widespread disease.
