Frequent question: Which tumors are considered germ cell tumors?

What are the two types of germ cell tumors?

There are two types of germ cell tumors that start in the gonads, or reproductive organs: seminomas, which are slower-growing, and nonseminomas, which are faster-growing tumors. These germ cell tumors typically form during puberty.

What are the germ cell tumors?

Germ cell tumors are growths of cells that form from reproductive cells. The tumors may be cancerous or not cancerous. Most germ cell tumors occur in the testicles or the ovaries. Some germ cell tumors occur in other areas of the body, such as the abdomen, brain and chest, though it’s not clear why.

What is the most common germ cell tumor?

Teratomas are the most common type of germ cell tumor to develop in extragonadal (not in the ovary or testes) areas. Doctors usually treat teratomas with surgery because chemotherapy doesn’t work in a benign tumor.

What is the survival rate of germ cell tumor?

The survival and cure rates also depend on several factors, including the stage of the disease. The cure rate for children with a stage I or stage II germ cell tumor is 90%. The cure rate for a stage III tumor is 87%. The cure rate for a stage IV tumor is 82%.

Do germ cell tumors grow fast?

This is a germ cell tumor that is most often malignant, but may also be benign. This tumor most often affects the ovaries or testes, and the lower spine. They are often malignant and grow fast.

Is germ cell tumor curable?

Treatment for malignant tumors includes surgery or chemotherapy. The outlook depends on the stage of the cancer, the tumor’s size and whether it has spread to other parts of your body. Most germ cell tumors are treatable.

What percentage of germ cell tumors are cancerous?

Germ cell tumors are rare. Germ cell tumors account for about 2 to 4 percent of all cancers in children and adolescents younger than age 20. Germ cell tumors can spread (metastasize) to other parts of the body. The most common sites for metastasis are the lungs, liver, lymph nodes, and central nervous system.

What percentage of germ cell tumors are malignant?

Malignant germ cell tumors of the mediastinum are uncommon, representing only 3 to 10% of tumors originating in the mediastinum. They are much less common than germinal tumors arising in the testes, and account for only 1 to 5% of all germ cell neoplasms.

Is germ cell tumors aggressive?

They form in the testicles and ovaries. It’s often an aggressive cancer that spreads quickly to the lymph nodes and other parts of the body. They’re typically treated with surgery and chemotherapy.

How is germ cell tumors diagnosed?

A biopsy is the removal of a small amount of tissue for examination under a microscope. Other tests can suggest that a germ cell tumor is present, but only a biopsy can make a definite diagnosis and determine if the tumor is benign or cancerous. A pathologist then analyzes the sample(s).

Do germ cell tumors run in families?

Familial testicular germ cell tumors are well known in literature. Only few cases are reported where both brother and sister of the same family suffered from germ cell malignancies.
