markers and interventions are defıned at the outset. The National<br />

Cancer Institute (NCI) MATCH prospective clinical trial<br />

will open for patients age 18 or older in which standard therapy<br />

has failed and who are willing to undergo a rebiopsy. 44 Analysis<br />

of approximately 200 genes that have been selected for alignment<br />

with a targeted agent will be performed in one of four<br />

Clinical Laboratory Improvement Amendment-certifıed laboratories.<br />

The trial will use FDA-approved drugs outside of their<br />

indication as well as agents not yet approved but that have<br />

shown activity in a given tumor type. The NCI MATCH study<br />

will be open to all four adult cooperative groups. NCI is now<br />

planning a Pediatric MATCH study with COG, thus, paving the<br />

way for precision medicine for all COG members.<br />

SUMMARY AND CONCLUSIONS<br />

Next-generation genomic analysis of pediatric tumors has<br />

yielded profound insights into the origins of childhood cancers<br />

and has shed light on biologic pathways that drive tumorigenesis<br />

and drug resistance. Integration of new agents<br />

on a backbone of traditional therapy is being pursued in<br />

many tumor types, and there is great anticipation that such<br />

approaches will lead to improved outcomes. The integration<br />

of NGS into therapeutic decision making for individual patients<br />

poses many technical, fınancial, and biologic challenges.<br />

It may be anticipated that such hurdles will be<br />

overcome through careful application of precision medicine<br />

in the context of rigorous clinical trials.<br />
