Trophoblastic diseases treatment

Trophoblastic diseases are rare diseases that can develop in connection with pregnancy. In our specialized gynaecological cancer center, we treat these with surgery and/or chemotherapy. The therapy depends on the type and spread of the disease.

Trophoblastic diseases develop from the tissue that forms during pregnancy to nourish the embryo (trophoblast). It is a group of diseases that can be benign (benign) or malignant (malignant). The most important forms include

  • Bubble mole (hydatiform mole)
  • Invasive mole
  • Chorionic carcinoma
  • Rarer: placental site trophoblastic tumor (PSTT) and epithelioid trophoblastic tumor (ETT)

Trophoblastic diseases occur in around 0.5 in 1,000 pregnancies and can develop both during and after pregnancy.

Diagnosis with us

Various examinations are carried out to clarify the situation:

  • Medical interview and physical examination
  • Gynecological examination
  • Ultrasound of the uterus
  • Blood test for the pregnancy hormone beta-hCG

A precise diagnosis is important in order to select the appropriate treatment.

Treatment options for trophoblastic diseases

The type of treatment depends on the type of disease. We offer the following treatment options at our center:

Surgery

The most common treatment for a bladder mole is scraping out the uterus (curettage), often using suction. In certain cases – especially if family planning is complete or the disease is advanced – it may be necessary to remove the uterus (hysterectomy).

Curettage is a routine procedure in gynecology in which the mucous membrane is removed from the inside of the uterus. The procedure is usually performed under a short general anesthetic and is often combined with a hysteroscopy in order to better assess the uterine cavity.

Even if the operation only lasts a short time, patients are monitored in the recovery room afterwards in order to detect complications such as post-operative bleeding at an early stage. Mild abdominal cramps and bleeding may occur for a few days.

For the first few days after the operation we recommend

  • Use pads instead of tampons to reduce the risk of infection.
  • To take it easy physically.
  • Severe or persistent pain, fever or unusually heavy bleeding should be checked by a doctor immediately.

Chemotherapy

Chemotherapy is the most important treatment for malignant forms such as invasive mole or chorionic carcinoma. Different medications are used depending on the risk group. We plan chemotherapy for trophoblastic diseases individually for each patient, depending on the tumor stage, general condition and concomitant diseases, and monitor it regularly with blood tests (beta-hCG) to check the success of the treatment. Chemotherapy is usually carried out on an outpatient basis in our day clinic.

Aftercare

After treatment, regular check-ups at our center are important in order to detect a recurrence at an early stage. These include:

  • Regular blood tests (beta-hCG)
  • Gynecological examinations

During follow-up care, it is recommended to refrain from a new pregnancy until the checks have been completed.

Second opinion

We also offer second opinions for externally diagnosed and treated trophoblastic diseases. Please register for this via our referral form.

Frequently asked questions about the treatment of trophoblastic diseases

In most cases, it is possible to become pregnant again after treatment and aftercare have been completed. Your treatment team will advise you individually.

Most trophoblastic diseases are very treatable today. The chances of recovery are very high – especially with early diagnosis and treatment in a specialized gynaecological tumor center.
