Abstract

We report a case of infantile fibrosarcoma in an 8-month-old boy manifested as a right-sided lower leg mass. Repeated local recurrence and distant metastasis were noted during the following three-year period. Whole body fluoro-deoxyglucose positron emission tomography scan revealed an asymptomatic metastasis involving the fourth lumbar vertebrae. The patient received chemotherapy (VAC regimen) with Cyberknife$^{(R)}$ stereotactic hypofractionated radiotherapy (26 Gy; 4 fractions). This treatment reduced tumor size by 23% without acute radiation toxicity even after 33 months. This case suggests that combining chemotherapy and this form of radiotherapy may be safe and effective against childhood spinal metastasis.
