title: Surgery of soft tissue sarcomas in children.
abstract: Surgery of soft tissue sarcomas in children has been modified by the introduction of multidisciplinary treatment so that major amputation and exenterations are now rare in the management of these tumors in children. Surgery must still be well planned for total removal of the tumor with preservation of limbs and, in most instances, the function of pelvic organs. The commonest soft tissue sarcomas in children are embryonal rhabdomyosarcoma (RMS), fibrosarcoma, and synovial sarcoma. Treatment of embryonal RMS can now achieve a 2-year survival of 80% at all sites. Surgery and irradiation are used to control the primary tumor and multidrug chemotherapy to control metastases or prevent dissemination of localized tumor. Fibrosarcoma in children, usually a low-grade, extra-abdominal desmoid lesion, does not respond to radiation treatment or chemotherapy, and management is by surgery alone. It shows a marked tendency to local recurrence, and multiple local resections may be necessary for cure. Ninety percent of the children with this tumor can be salvaged by surgery and careful follow-up. The management of synovial sarcoma is surgical and similar to that of RMS. Although not radiosensitive as is RMS, this tumor has responded well to multidisciplinary treatment. Adequate resection is now followed by a chemotherapy protocol similar to that used in osteogenic sarcoma. The smaller numbers of these tumors and their varied natural history make evaluation of treatment difficult. Other soft tissue sarcomas seen with extreme rarity in children are liposarcoma, angiosarcoma, and neurosarcoma. These tumors are treated with the same protocol as that of RMS.
