ON THIS PAGE: You will learn about how doctors describe a tumor’s growth or spread. This is called the stage. Use the menu to see other pages.
Staging is a way of describing where a tumor is located, if or where it has spread, and whether it is affecting other parts of the body. Doctors use diagnostic tests to find out the tumor's stage, so staging may not be complete until all of the tests are finished. Knowing the stage helps the doctor to decide what kind of treatment is best and can help predict a patient's prognosis, which is the chance of recovery. There are different stage descriptions for different types of tumors.
There are 2 types of staging for germ cell tumors, based on whether the patient has had surgery yet. First, the clinical stage is based on the results of tests done before surgery, such as a physical examination, CT scans, and MRI tests. Then, the pathologic stage is assigned based on information found during surgery, plus the laboratory results of any tissue removed during surgery. The stage provides a common way of describing the cancer so doctors can work together to plan the best treatments.
Cancer stage grouping
According to the Children’s Oncology Group, the following pathologic stages are used for germ cell tumors:
Stage I: The tumor has been entirely removed, and tumor markers are normal, or return to normal after surgery.
Stage II: Microscopic traces of the tumor are still present after surgery; tumor markers do not return to normal following surgery.
Stage III: Visible traces of tumor are left behind after initial treatment, and the lymph nodes are significantly affected.
Stage IV: The tumor has spread from its original site to other, more distant areas of the body.
Recurrent: A recurrent tumor is one that has come back after treatment. If the tumor does return, there will be another round of tests to learn about the extent of the recurrence. These tests and scans are often similar to those done at the time of the original diagnosis.
Information about the tumor’s stage will help the doctor recommend a specific treatment plan. The next section in this guide is Treatment Options. You may use the menu to choose a different section to read in this guide.
