Radiotherapy for persistent trophoblastic disease and choriocarcinoma

Persistent trophoblastic disease (PTD) is a tumour that can form in the womb after an abnormal type of pregnancy called a molar pregnancy.

Choriocarcinoma is a very rare tumour that can occur after a normal pregnancy, a molar pregnancy, a miscarriage or a termination of pregnancy (abortion).

These tumours are types of gestational trophoblastic disease (GTD).

When you might have radiotherapy

Radiotherapy for PTD and choriocarcinoma is rarely used. Usually you only have chemotherapy.

Your doctor might suggest you have radiotherapy to help reduce symptoms caused by persistent trophoblastic disease or choriocarcinoma that has spread from the womb to other parts of the body.

If your PTD or choriocarcinoma has spread to the brain you might have stereotactic radiotherapy. Stereotactic radiotherapy gives a high dose of radiotherapy to the disease in the brain.
