The National Cancer Institute (NCI) provides the PDQ pediatric cancer treatment information summaries as a public service to increase the availability of evidence-based cancer information to health professionals, patients, and the public.

Cancer in children and adolescents is rare. 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, an orthopedic surgeon experienced in bone tumors, a pathologist, radiation oncologists, pediatric oncologists, rehabilitation specialists, 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 summaries on Supportive and Palliative Care 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.[1] 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.

In recent decades, dramatic improvements in survival have been achieved for children and adolescents with cancer. 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.)

Osteosarcoma is a bone tumor that occurs predominantly in adolescents and young adults. It accounts for approximately 5% of childhood tumors. In children and adolescents, more than 50% of these tumors arise from the bones around the knee. There appears to be no difference in presenting symptoms, tumor location, and outcome for younger patients (<10 years) compared with adolescents.[2] Two trials conducted in the 1980s were designed to address the natural history of surgically treated localized, resectable osteosarcoma of the extremity. The outcome of patients in these trials who were treated with surgical removal of the primary tumor recapitulated the historical experience before 1970; more than half of these patients developed metastases within 6 months of diagnosis, and overall, almost 90% [3] developed recurrent disease within 2 years of diagnosis.[4] Overall survival for patients treated with surgery alone was statistically inferior.[5] The natural history of osteosarcoma has not changed over time, and fewer than 20% of patients with localized resectable primary tumors treated with surgery alone can be expected to survive free of relapse.[4,6-8]
