After surgery, patients with complete resection and with proven or possible chemosensitive histologies proceed to chemotherapy on the low-risk regimen. Patients with questionable completeness of resection proceed to chemotherapy for standard-risk or high-risk tumors, as appropriate. Regardless of resection results, patients who underwent scrotal surgery for paratesticular tumors proceed to chemotherapy for standard-risk tumors. Alveolar RMS is considered high risk.
