General Medical Information

Unusual Cancers of Childhood

This treatment information summary for children with unusual cancers is an overview of prognosis, diagnosis, classification, and treatment. The National Cancer Institute created the PDQ database to increase the availability of new treatment information and its use in treating patients. Information and references from the most recently published literature are included after review by pediatric oncology specialists.

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 incorporates the skills of the primary care physician, pediatric surgical subspecialists, radiation oncologists, pediatric medical oncologists/hematologists, rehabilitation specialists, pediatric nurse specialists, social workers, and others in order to ensure that children receive treatment, supportive care, and rehabilitation that will achieve optimal survival and quality of life. 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, there are clinical trials available for most of the 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 diagnosed with cancer are generally designed to compare potentially better therapy with therapy that is currently accepted as standard. Much 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.

The tumors discussed in this summary are diverse; the discussion is arranged in descending anatomic order, from infrequent tumors of the head and neck to rare tumors of the urogenital tract and skin. All of these cancers are rare enough that most pediatric hospitals might see fewer than two in a year. Most of these tumors are more frequent in adults with cancer; thus, much of the information about these tumors may also be sought through sources relevant to adults with cancer.
