Childhood extracranial germ cell tumors form from developing sperm or egg cells that travel to parts of the body other than the brain.
As a fetus develops, certain cells form sperm in the testicles or eggs in the ovaries. Sometimes these cells travel to other parts of the body and grow into germ cell tumors. This summary is about germ cell tumors that form in parts of the body that are extracranial (outside the brain). Extracranial germ cell tumors are most common in teenagers 15 to 19 years old.
Caring for a patient with cancer affects the family caregiver's quality of life.
Family caregivers usually begin caregiving without training and are expected to meet many demands without much help. A caregiver often neglects his or her own quality of life by putting the patient's needs first. Today, many health care providers watch for signs of caregiver distress during the course of the patient's cancer treatment. When caregiver strain affects the quality of caregiving, the patient's well-being...
Childhood extracranial germ cell tumors are grouped as gonadal or extragonadal.
Malignant extracranial germ cell tumors are grouped into gonadal and extragonadal.
Gonadal Germ Cell Tumors
Gonadal germ cell tumors form in the testicles or ovaries.
Testicular Germ Cell Tumors
Testicular germ cell tumors usually occur before the age of 4 years or in teenagers and young adults.
Testicular germ cell tumors in teenagers and young adults are different from those that form in early childhood. They are more like testicular cancer in adults. Testicular germ cell tumors are divided into two main types, seminoma and nonseminoma. (See the PDQ summary on Testicular Cancer Treatment for more information.)
Seminoma: These tumors make a hormone called beta-human chorionic gonadotropin (β-hCG).
Nonseminoma: These tumors are usually large and cause symptoms. They tend to grow and spread more quickly than seminomas.
