Phase I Study of Safety and Feasibility of Transarterial Embolization of Incurable Hypervascular Pediatric Soft Tissue Sarcomas

Brief Summary

This is a single center, single arm phase I clinical trial exploring the feasibility and safety of performing transarterial embolization of incurable hypervascular pediatric soft tissue sarcomas with at least an index tumor with 50% arterial enhancement and a 3mm feeding vessel on pre study evaluation. The target study sample size is 10 tumors in a requisite number of participants. These patients will be enrolled to undergo evaluation of all angiographically visible tumors \>3cm with subsequent bland (not adsorbed to radioactive or chemotherapy) particle embolization of at least 25% perfusion to the target tumor.
