TGen-led research shows ability to do next-generation sequencing for patients with advanced cancers
Date:10/30/2013

SCOTTSDALE, Ariz. Oct. 30, 2013 A pilot study led by the Translational Genomics Research Institute (TGen) and the Virginia G. Piper Cancer Center at Scottsdale Healthcare shows that, even for patients with advanced and rapidly transforming cancer, researchers can find potential therapeutic targets using the latest advances in genomic sequencing.

Sequencing spells out, or decodes, the billions of letters of DNA and other genomic data so that clinicians can discover what genetic changes might lead to cancer.

Better optics and faster computers, which are the hallmarks of today's Next Generation Sequencing (NGS), are leading to genomic analysis that enables development of new drugs that target specific genetic mutations. However, because patients' tumors often contain multiple abnormalities, their cancer often progresses beyond initial targeted therapies.

Researches showed that the most cutting-edge NGS whole genome sequencing (WGS), and even more advanced whole transcriptome sequencing (WTS) can reveal larger numbers of targets in an individual's tumor, and that these "could be addressed using specific therapeutic agents, and perhaps reduce the chance of progression," according to the pilot study published today in the scientific journal PLOS ONE.

The study A Pilot Study Using Next Generation Sequencing in Advanced Cancers: Feasibility and Challenges reported results on nine patients evaluated at the Virginia G. Piper Cancer Center Clinical Trials at Scottsdale Healthcare, a partnership of Scottsdale Healthcare and TGen.

"Patients with advanced cancer often exhaust treatment options. Targeting a single abnormality is not sufficient to prevent progression," said Dr. Glen Weiss, an Associate Professor in TGen's Cancer and Cell Biology Division and the study's lead author.

"We demonstrate the feasibility of using NGS in advanced cancer patients so that treatments for patients with progressing tumors
