Current Clinical Trials

The prognosis for children with metastatic soft tissue sarcomas is poor,[1-6] and these children should receive combined treatment with chemotherapy, radiation therapy, and surgical resection of pulmonary metastases. In a prospective randomized trial, chemotherapy with vincristine, dactinomycin, doxorubicin, and cyclophosphamide with or without dacarbazine led to tumor responses in one-third of patients with unresectable or metastatic disease. The estimated 4-year survival rate, however, was poor, with fewer than one-third of the children surviving.[6-8]

Children with isolated pulmonary metastases should undergo exploratory thoracotomy in an attempt to resect all gross disease. The estimated 5-year survival rate after thoracotomy for pulmonary metastasectomy has ranged from 10% to 58% in adult studies. Formal segmentectomy, lobectomy, and mediastinal lymph node dissection are unnecessary.[9]

Vincristine, doxorubicin, and ifosfamide with granulocyte colony-stimulating factor have been used in patients with unresected or metastatic tumors. The Pediatric Oncology Group evaluated the combination of doxorubicin and ifosfamide in children with unresected or metastatic soft tissue sarcomas because several adult trials have suggested that ifosfamide-based regimens may be superior to other chemotherapeutic regimens for soft tissue sarcomas.[10]

Check for U.S. clinical trials from NCI's PDQ Cancer Clinical Trials Registry that are now accepting patients with metastatic childhood soft tissue sarcoma. 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.
