Extragonadal Germ Cell Tumors Treatment

Stages of Extragonadal Germ Cell Tumors

After an extragonadal germ cell tumor has been diagnosed, tests are done to find out if cancer cells have spread to other parts of the body.

The extent or spread of cancer is usually described as stages. For extragonadal germ cell tumors, prognostic groups are used instead of stages. The tumors are grouped according to how well the cancer is expected to respond to treatment. It is important to know the prognostic group in order to plan treatment.

There are three ways that cancer spreads in the body.

The three ways that cancer spreads in the body are:

When cancer cells break away from the primary (original) tumor and travel through the lymph or blood to other places in the body, another (secondary) tumor may form. This process is called metastasis. The secondary (metastatic) tumor is the same type of cancer as the primary tumor. For example, if breast cancer spreads to the bones, the cancer cells in the bones are actually breast cancer cells. The disease is metastatic breast cancer, not bone cancer.

The following prognostic groups are used for extragonadal germ cell tumors:

Good prognosis

A nonseminoma extragonadal germ cell tumor is in the good prognosis group if:

A seminoma extragonadal germ cell tumor is in the good prognosis group if:

Intermediate prognosis

A nonseminoma extragonadal germ cell tumor is in the intermediate prognosis group if:

A seminoma extragonadal germ cell tumor is in the intermediate prognosis group if:

Poor prognosis

A nonseminoma extragonadal germ cell tumor is in the poor prognosis group if:

Seminoma extragonadal germ cell tumor does not have a poor prognosis group.
