Genomic analysis of circulating tumor DNA (ctDNA) is increasingly incorporated into the clinical management patients with advanced cancer. Beyond profiling, ctDNA also can enable calculation fraction (TF), which has previously been found to be prognostic. While most prognostic models in metastatic cancer are type specific and require significant patient-level data, quantification TF potential serve as a pragmatic, tumor-agnostic tool.This study utilized cohort nationwide de-identified...
One of the great challenges in therapeutic oncology is determining who might achieve survival benefits from a particular therapy.

Abstract Introduction: Distinguishing the origin of variants detected by LBx is essential as tumor-somatic and germline, but not CH variants, can provide prognostic insights inform treatment decisions. We describe a machine learning model that generates variant predictions for SVs (including base substitutions short indels) LBx. Method: For all in FoundationOne®Liquid CDx (F1LCDx) assay, VOP 3-way probability originated CH, or tumor-somatic. Tumor-somatic germline probabilities be summed to...
A majority of patients with metastatic colorectal cancer (mCRC) experience recurrence post curative-intent surgery. The addition adjuvant chemotherapy has shown to provide limited survival benefits when applied all patients. Therefore, a biomarker assess molecular residual disease (MRD) accurately and guide treatment selection is highly desirable for high-risk This feasibility study evaluated the prognostic value tissue comprehensive genomic profiling (CGP)-informed, personalized circulating...
In 2001, genetic testing for BRCA1 and BRCA2 was introduced in Ontario, women at high-risk of breast or ovarian cancer. To date over 30,000 individuals have been tested throughout Ontario. Testing offered to all Ontario residents who were eligible under any 13 criteria. We report the results tests conducted Mount Sinai Hospital from 2007 2014. A total 4726 tested, 764 (16.2%) found carry a pathogenic variant (mutation). Among 3684 men underwent without known familial BRCA mutation, 331...
Abstract Introduction: Monitoring of ctDNA can be a minimally invasive complement to tumor imaging for assessing treatment effect. Technical limitations require methods distinguish signal from clonal hematopoiesis (CH), often including non-tumor sequencing. We developed tumor-naïve panel (FoundationOne® Monitor) quantify fraction (TF). TF analytical validation used peripheral blood mononuclear cell (PBMC) then leveraged plasma collected serially patients with aNSCLC in the real-world (rw)...
Circulating tumor DNA (ctDNA) detection postoperatively may identify patients with urothelial cancer at a high risk of relapse. Pragmatic tools building off clinical next-generation sequencing (NGS) platforms could have the potential to increase assay accessibility.We evaluated widely available Foundation Medicine comprehensive genomic profiling (CGP) platform as source variants for tracking ctDNA when analyzing residual samples from IMvigor010 (ClinicalTrials.gov identifier NCT02450331),...
Emerging technologies focused on the detection and quantification of circulating tumor DNA (ctDNA) in blood show extensive potential for managing patient treatment decisions, informing risk recurrence, predicting response to therapy. Currently available tissue-informed approaches are often limited by need additional sequencing normal tissue or peripheral mononuclear cells identify non-tumor-derived alterations while tissue-naïve sensitivity.
