Abstract
Rhabdomyosarcoma (RMS) is a tumor primarily of mesenchymal origin that
comprises approximately half of all pediatric sarcomas, which make up
7% of all pediatric tumors. The focus of this manuscript will include
recent changes in surgical and local control therapy of RMS. We will
discuss surgical therapy principles including improved outcomes
associated with complete surgical resection of the primary tumor either
prior to the initiation of chemotherapy or after induction of
chemotherapy, and in the setting of metastatic disease. We will also
discuss the increasing utilization of core needle biopsy for diagnosis
and the use of sentinel node biopsy techniques to determine the presence
of nodal disease. There have been refinements regarding optimal
prognostic factors including the adoption of fusion status over
histology, as well as updated risk stratification schemas to assure
optimal therapy. Since this manuscript is an international
collaboration, part of the discussion will also focus on comparisons
between North American and European surgical paradigms.
