Principles in the management of pediatric intestinal leiomyosarcomas.
Primary intestinal leiomyosarcomas in children are unusual tumors with little known about their natural history. Two patients (aged 9 and 10 years) with leiomyosarcoma of the jejunum treated at our institution are reported and added to the 20 other patients reported in the literature. The first patient had a grade 1 leiomyosarcoma completely resected, received no additional therapy, and remains alive with no evidence of disease 14 years later. The second patient presented with a perforated grade 2 leiomyosarcoma which was incompletely resected; he received combination chemotherapy with an initial good response, but eventually died from sarcomatosis 7 years after initial diagnosis. The 22 cases of pediatric intestinal leiomyosarcoma presented more commonly with obstruction or perforation, were able to be completely resected more often, and appear to have a better prognosis than in adults. Thus, intestinal leiomyosarcomas in children appear to have a natural history different from that of the same tumor arising in adults.
