Outline of Final Research Achievements |
This study aims to establish customized NGS panels to detect circulating tumor DNA (ctDNA) from various solid tumors. Two panels were established: JFCR cfDNA screening panel for cancer screening and JFCR cfDNA actionable mutation panel for alterations detection with therapeutic implication. JFCR screening panel is a 33 cancer gene panel, designed after assessing mutation profiles from TCGA and COSMIC databases. By using reference standard, JFCR cfDNA screening panel was able to detect mutation as low as 0.2% of molecular allele frequency. ctDNA detection rate varies among solid cancers and stages, range between 50-67% by using this panel. JFCR cfDNA actionable mutation panel is a 59 gene panel that covers actionable mutations, copy number variations and fusions. The average ctDNA detection rate is 79% in various solid tumor with limit of detection at 0.1%. This study include only very small sample size, further studies are needed to evaluate the feasibility of these panels.

Academic Significance and Societal Importance of the Research Achievements |
Next generation sequencing (NGS) of circulating tumor DNA (ctDNA) enables the evaluation of genetic profiles of the primary and metastatic tumor sites. This study established customize ctDNA NGS panels that could be used for detection, monitoring and treatment selection for cancer patients.
