Palbociclib in Treating Patients With Relapsed or Refractory Rb Positive Advanced Solid Tumors, Non-Hodgkin Lymphoma, or Histiocytic Disorders With Activating Alterations in Cell Cycle Genes (A Pediatric MATCH Treatment Trial)

This phase II Pediatric MATCH trial studies how well palbociclib works in treating patients with Rb positive solid tumors, non-Hodgkin lymphoma, or histiocytic disorders with activating alterations (mutations) in cell cycle genes that have spread to other places in the body and have come back or do not respond to treatment. Palbociclib may stop the growth of cancer cells by blocking some of the proteins needed for cell growth.
