Childhood Soft Tissue Sarcoma Treatment (PDQ®): Treatment - Health Professional Information [NCI] - General Information

Fortunately, cancer in children and adolescents is rare, although the overall incidence of childhood cancer has been slowly increasing since 1975.[1] Children and adolescents with cancer should be referred to medical centers that have a multidisciplinary team of cancer specialists with experience treating the cancers that occur during childhood and adolescence. This multidisciplinary team approach incorporates the skills of the primary care physician, pediatric surgical subspecialists, pediatric radiation oncologist, pediatric hematologist/oncologist, rehabilitation specialist, pediatric nurse specialists, social workers, and others to ensure that children receive treatment, supportive care, and rehabilitation that will achieve optimal survival and quality of life. Refer to the PDQ Supportive and Palliative Care summaries for specific information about supportive care for children and adolescents with cancer.

Guidelines for pediatric cancer centers and their role in the treatment of pediatric patients with cancer have been outlined by the American Academy of Pediatrics.[2] At these pediatric cancer centers, clinical trials are available for most types of cancer that occur in children and adolescents, and the opportunity to participate in these trials is offered to most patients/families. Clinical trials for children and adolescents with cancer are generally designed to compare potentially better therapy with therapy that is currently accepted as standard. Most of the progress made in identifying curative therapies for childhood cancers has been achieved through clinical trials. Information about ongoing clinical trials is available from the NCI Web site.

Dramatic improvements in survival have been achieved for children and adolescents with cancer. Between 1975 and 2002, childhood cancer mortality has decreased by more than 50%.[1] Childhood and adolescent cancer survivors require close follow-up because cancer therapy side effects may persist or develop months or years after treatment. Refer to the PDQ summary on Late Effects of Treatment for Childhood Cancer for specific information about the incidence, type, and monitoring of late effects in childhood and adolescent cancer survivors.

Incidence

Pediatric soft tissue sarcomas (STSs) are a heterogenous group of malignant tumors that originate from primitive mesenchymal tissue and account for 7% of all childhood tumors.[3] Multidisciplinary evaluation in centers that have surgical and radiotherapeutic expertise is of critical importance to ensure the best clinical outcome for these patients. Although surgery with or without radiation therapy can be curative for a significant proportion of patients, the addition of chemotherapy might benefit subsets of children with the disease; therefore, enrollment into clinical trials is encouraged.

Rhabdomyosarcoma, a tumor of striated muscle, is the most common STS in children aged 0 to 14 years and accounts for 50% of tumors in this age group.[4] (Refer to the PDQ summary on Childhood Rhabdomyosarcoma Treatment for more information.) The remaining STSs are commonly referred to as nonrhabdomyosarcomatous STSs and account for about 3% of all childhood tumors.[5] This heterogeneous group of tumors includes neoplasms of:[6]

  • Connective tissue (e.g., desmoid fibromatosis, liposarcoma).
  • Peripheral nervous system (e.g., malignant peripheral nerve sheath tumor).
  • Smooth muscle (e.g., leiomyosarcoma).
  • Vascular tissue (blood and lymphatic vessels, e.g., angiosarcoma).

In children, synovial sarcoma, fibrosarcoma, fibrohistiocytic tumors, and malignant peripheral nerve sheath tumors predominate.[7,8] The distribution of STSs by histology and age, based on the Surveillance Epidemiology and End Results (SEER) information from 1975 to 2008, is depicted in Table 1. The distribution of histologic types by age is shown in Figure 1.
