Main pathological features Three subtypes of embryonal RMS (primitive and intermediate). The main difference between the three subgroups was the number of rhabdomyoblasts Mixture of spindle cell and sclerosing features. Only 63% of cases showed rhabdomyoblasts The most common subtype was alveolar RMS (46.7%), followed by embryonal RMS (30.0%), spindle cell/sclerosing RMS, and pleomorphic RMS
Treatment Surgical resection and chemotherapy Combination of surgery, VAC chemotherapy, and/or radiotherapy Surgery, chemotherapy, and radiotherapy (singular or combined)
Surgery Tumor resection Local excision, palatectomy, neck resection, orbit resection Tumor resection
Chemotherapy protocol • VCR, actinomycin D
• Adriamycin and cyclophosphamide (stages I, II, III)
• Stage IV Ifosfamide replaces cyclophosphamide
• 11 (68.8) VAC
• 4 (25.0) VCR, CDDP and THP-ADR
