MedicalResearch.com: What is the background for this study? What are the main findings?

Response: 30% of patients with newly diagnosed advanced NSCLC can be treated successfully with targeted therapies, often yielding higher response rates than chemotherapy or immune checkpoint inhibitors. Selecting first-line therapy for patients with NSCLC requires assessment of an expanding list of guideline-recommended genomic biomarkers (EGFR, ALK, ROS1, BRAF, RET, MET amplification and exon 14 skipping, and ERBB2, with NTRK newly added)

Standard-of-care (SOC) testing relies on tissue, which is limited by biopsy-related risks, specimen insufficiency, and lab processing duration, which hamper timely optimal treatment selection

–          NILE is a large, prospective, multicenter, head-to-head study of SOC tissue-based genomic testing to plasma-based comprehensive cfDNA genomic testing (Guardant360®). For the four biomarkers with FDA approved therapies, up to 34% of patients were tested by SOC tissue testing versus 95% with cfDNA testing. NILE met its primary endpoint – cfDNA performed similar to tissue in the detection of guideline-recommended biomarkers and cfDNA results were delivered significantly faster than SOC tissue testing (median 9 days vs. 15 days).Using cfDNA testing first, 87% of patients with a guideline-recommended biomarker would have been detected, compared to 67% if SOC tissue testing was first.

Misdiagnosis Common Among Young Adults With Colon Cancer

MedicalResearch.com Interview with:
Ronit Yarden, PhD, MHSA
Director of Medical Affairs
Colorectal Cancer Alliance, a patient advocacy organization
Washington, D.C. 

MedicalResearch.com: What is the background for this study? What are the main findings? 

Response: The colorectal Cancer Alliance is a patient advocacy group (the largest advocacy group for colorectal cancer) and its mission is to provide support to patients, survivors, their caregivers and family members as well as advocate on their behalf for.  The organization is also committed to raise awareness for screening and early detection of colorectal cancer to help save lives and to provide funding for innovative colorectal cancer research.

As part of our support we sought to identify some of the clinical, emotional and financial experiences and unmet needs of patients under 50 years old.  We conducted an online survey that was promoted through social media and 1195 patients and survivors completed our survey.  Continue reading
