• The tumor is found only in the testicle or in the retroperitoneum (area outside or behind the abdominal wall); and
• The tumor has not spread to organs other than the lungs; and
• The levels of all the tumor markers are slightly above normal.

For seminoma, all of the following must be true:

• The tumor has not spread to organs other than the lungs; and
• The level of alpha-fetoprotein (AFP) is normal. Beta-human chorionic gonadotropin (β-hCG) and lactate dehydrogenase (LDH) may be at any level.

Intermediate Prognosis

For nonseminoma, all of the following must be true:

• The tumor is found in one testicle only or in the retroperitoneum (area outside or behind the abdominal wall); and
• The tumor has not spread to organs other than the lungs; and
• The level of any one of the tumor markers is more than slightly above normal.

For seminoma, all of the following must be true:

• The tumor has spread to organs other than the lungs; and
• The level of AFP is normal. β-hCG and LDH may be at any level.

Poor Prognosis

For nonseminoma, at least one of the following must be true:

• The tumor is in the center of the chest between the lungs; or
• The tumor has spread to organs other than the lungs; or
• The level of any one of the tumor markers is high.

There is no poor prognosis grouping for seminoma testicular tumors.
