Auto Transplant for High Risk or Relapsed Solid or CNS Tumors

Study Overview
=================
Brief Summary
-----------------
This is a standard of care treatment guideline for high risk or relapsed solid tumors or CNS tumors consisting of a busulfan, melphalan, thiotepa conditioning (for solid tumors) or carboplatin and thiotepa conditioning (for CNS tumors) followed by an autologous peripheral blood stem cell transplant. For solid tumors, if appropriate, disease specific radiation therapy at day +60. For CNS tumors, the conditioning regimen and autologous peripheral blood stem cell transplant will be given for 3 cycles.
