Stereotactic Radiation Therapy for Pediatric Sarcomas


I'm Interested

Trial ID: NCT01763970


The stereotactic body radiation therapy (SBRT) literature focuses on clinical outcomes in the adult population. However, SBRT has a particularly strong rationale for application in pediatrics given that high biologically effective doses have been shown to increase control in histologies, such as sarcoma, which are common in the pediatrics population. With stereotactic radiation therapy techniques, a reduction in normal tissue dose surrounding the target lesion of interest may also be accomplished resulting in lower toxicity. Given that pediatric patients with sarcomas, presenting with limited metastases in lung and bone, are still considered to be a curable population with aggressive local therapy, SBRT could have a significant impact on outcomes in oligometastatic patients who may be otherwise unresectable.
