Childhood Extracranial Germ Cell Tumors Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Treatment of Malignant Extragonadal Extracranial GCTs in Children

continued...

Most mediastinal GCTs in adolescents and young adults occur in males, and 22% to 50% have cytogenetic changes consistent with Klinefelter syndrome.[14,15] The age of presentation is younger in patients with Klinefelter syndrome.[14,15] As with sacrococcygeal tumors, primary chemotherapy is usually necessary to facilitate surgical resection of mediastinal GCTs, and the completeness of resection is a very important prognostic indicator.[6,16] Survival rates for the older adolescent and young adult population with mediastinal tumors are generally less than 60%.[4,17,18,19]; [20][Level of evidence: 3iiA]

Patients with a malignant mediastinal primary tumor and extracranial metastases are at the highest risk of developing brain metastases and are monitored closely for signs and symptoms of central nervous system involvement.[21][Level of evidence: 3iiB] (Refer to the PDQ summary on Extragonadal Germ Cell Tumors Treatment for more information about the treatment of adult patients.)

Malignant Extragonadal Extracranial GCTs (Retroperitoneum)

Malignant GCTs located in the retroperitoneum or abdomen usually present in children before the age of 5 years; most tumors are of advanced stage and locally unresectable at diagnosis.[22] A limited biopsy followed by platinum-based chemotherapy to shrink tumor bulk can lead to complete tumor resection in most patients. Despite the advanced-stage disease in most patients, the 6-year EFS using PEB was 83% in the Pediatric Oncology Group/Children's Cancer Group intergroup study.[22]

Malignant Extragonadal Extracranial GCTs (Head and Neck Sites)

Although rare, benign and malignant GCTs can occur in the head and neck region, especially in infants. Often the airway is threatened. Surgery for nonmalignant tumors and surgery plus chemotherapy for malignant tumors can be curative.[23][Level of evidence: 3iiiDii]

Current Clinical Trials

Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with childhood extragonadal germ cell tumor. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.

General information about clinical trials is also available from the NCI Web site.
