Workup
Laboratory Studies
- Perform routine chemistries and CBC count with differential and platelets to obtain basic baseline information prior to administration of general anesthesia or chemotherapy.
Imaging Studies
- The goal of the evaluation in a patient with a suspected rhabdomyosarcoma should be to define the local extent of the tumor (ie, resectability), lymph node involvement, and distant metastasis.
- CT scanning or MRI of the primary tumor is necessary to assess the size of the tumor and its extension into adjacent structures. These studies also assist in narrowing the differential diagnoses. Positron emission tomography (PET)/CT scanning may prove to be valuable in staging and preoperative evaluation of pediatric rhabdomyosarcoma.6
- Perform a bone scan to rule out metastatic disease to the skeletal structures.
- A CT scan of the chest is also recommended to rule out metastasis to the pulmonary parenchyma.
Diagnostic Procedures
- Evaluate the bone marrow using bone marrow aspiration to rule out metastatic spread to the bone marrow.
Histologic Findings
The diagnosis of rhabdomyosarcoma should be confirmed through a tissue specimen, which may be attained via fine needle, core, incisional, or excisional biopsy. The characteristic histologic finding of rhabdomyosarcoma is that of a small, blue, round cell. Cross striations may be seen with light microscopy. The histologic subtypes are discussed in Pathophysiology. For additional information, see the article Rhabdomyosarcoma in eMedicine’s Pathology volume.
Staging
Once the diagnosis of rhabdomyosarcoma has been made, the tumor should be staged. The staging system currently used for rhabdomyosarcomas is the Lawrence/Gehan Staging System, which is initiated preoperatively and then completed after resection.
- Stage and primary disease sites
- Stage 1 - Orbit/eyelid, head and neck (excluding parameningeal [PM]), genitourinary (excluding bladder/prostate)
- Stage 2 - Bladder/prostate, extremity, PM, other (eg, trunk, retroperitoneum), smaller than 5 cm
- Stage 3 - Bladder/prostate, extremity, PM, other (eg, trunk, retroperitoneum), larger than 5 cm
- Stage 4 - All others
- IRS Group postsurgical pathologic grouping
- Group I - Localized disease, completely resected (clear margins, negative regional nodes)
- Group II - Microscopic disease remaining (at margins or in regional nodes)
- Group III - Incomplete resection or biopsy findings indicating gross residual disease (locally or in regional nodes)
- Group IV - Distant metastases present at onset
