(ACTION) Adoptive Cellular Therapy following Dose-Intensified Temozolomide in Newly-diagnosed Pediatric High-grade Gliomas


It is believed that the body's immune system protects the body by attacking and killing tumor cells. T-lymphocytes (T-cells) are part of the immune system and can attack when they recognize special proteins on the surface of tumors. In most patients with advanced cancer, T-cells are not stimulated enough to kill the tumor.

In this research study, we will use a patient's tumor to make a vaccine which we hope will stimulate T-cells to kill tumor cells and leave normal cells alone.
