Аннотация
BACKGROUND: Alveolar soft part sarcoma (ASPS) is a rare type of soft tissue sarcoma. The infrequency of ASPS is such that it accounts for <1% of all soft tissue sarcomas and <0.1% of sarcomas concerning the head and neck, primarily those involving the orbit (48%) and tongue (25%). Traditional chemotherapy or radiotherapy of ASPS is often associated with poor outcome, even after comprehensive interventions.
METHODS AND RESULTS: We performed iodine-125 ((125) I) seed brachytherapy under ultrasound guidance through a submandibular puncture in a 4-year-old boy with recurrent ASPS of the tongue. The prescription dose was 120 Gy; therefore, 35 (125) I seeds were implanted with 0.77 mCi per seed, the total amount of activity being 26.95 mCi. CT scans confirmed a complete response after the treatment.
CONCLUSION: Our patient now has a recurrent-free survival of >30 months, an amount of time longer than the median rate described in the literature.
