Childhood Extracranial Germ Cell Tumors Treatment (PDQ®): Treatment - Patient Information [NCI] - Treatment Option Overview
Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your child's condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups.
For childhood extracranial germ cell tumors, alpha-fetoprotein (AFP) tests are done to see if treatment is working. Continued high levels of AFP may mean the cancer is still growing. For at least 3 years after surgery, follow-up will include regular physical exams, imaging tests, and tumor marker tests.
