Background: Only a few reports on the clinical features and management of childhood leiomyosarcoma are available. To contribute additional information on the management of this rare tumor, we report on a series of 16 pediatric patients treated from 1982 to 1998 by the Soft Tissue Sarcoma Italian Cooperative Group. Patients and methods: Primary surgery was conservative in all but two patients, and consisted of biopsy - three cases, non-radical excision - four, and radical resection - nine (involving a primary re-excision in 4 of 9). In two cases secondary radical surgery was performed after primary chemotherapy. Chemotherapy was administered to 9 of 16 patients, radiotherapy to three. Results: After a median follow-up of seven years (range 3-18), the five-year event-free survival (EFS) and overall survival were 56.3% and 72.9%, respectively; 12 of 16 patients were alive (nine of them in continuos complete remission). Univariate analysis was performed to compare EFS according to different subgroups: size represented the most significant prognostic factor. Conclusions: Complete surgical resection is the mainstay of treatment for leiomyosarcoma. The role of both adjuvant chemotherapy and radiotherapy has yet to be established, and awaits cooperative multicentric studies.
