Abstract
This Pediatric MATCH screening and multi-sub-study phase II trial studies how well treatment
that is directed by genetic testing works in pediatric patients with solid tumors,
non-Hodgkin lymphomas, or histiocytic disorders that have progressed following at least one
line of standard systemic therapy and/or for which no standard treatment exists that has been
shown to prolong survival. Genetic tests look at the unique genetic material (genes) of
patients' tumor cells. Patients with genetic changes or abnormalities (mutations) may benefit
more from treatment which targets their tumor's particular genetic mutation, and may help
doctors plan better treatment for patients with solid tumors or non-Hodgkin lymphomas.
