Foresight Diagnostics’ PhasED-Seq detects circulating tumor DNA at extremely low levels

Foresight Diagnostics Inc. has developed a circulating tumor DNA (ctDNA) detection platform for detecting minimal residual disease (MRD) in B-cell lymphomas, a form of non-Hodgkin lymphoma and the most common lymphoma in the U.S., accounting for about 85% of all cases. Now, it has published data showing its phased variant enrichment detection sequencing (PhasED-Seq) nearly doubled the identification of patients with aggressive lymphoma who were not cured by standard therapy and need new treatment options.

Following Cancer Progress in Real Time

HOUSTON – University of Houston engineering researcher Wei-Chuan Shih has been awarded $2.7 million from the National Institute of Biomedical Imaging and Bioengineering to detect cancer biomarkers in blood by counting exosomes. Known as “liquid biopsy,” the process, which requires only a simple blood draw, can improve the accuracy of measuring nearly invisible minimal residual disease (MRD) in cancer tumors.

ctDNA Identifies Patients Who Benefit From Immunotherapy in MIUC

Among patients with muscle-invasive urothelial carcinoma (MIUC), the presence of detectable circulating tumor DNA (ctDNA) after surgery may identify those who are likely to benefit from adjuvant immunotherapy with the immune checkpoint inhibitor atezolizumab (Tecentriq). The finding comes from a new analysis of data from the ImVigor010 trial, which had...

Circulating tumor DNA

This study states that HIV is an exclusion criterion for most lung cancer (LC) trials, however LC is the most common non-AIDS-defined malignancy in people living with HIV (PLHIV), poorer prognosis than the general population. Circulating tumor DNA (ctDNA) was a prognostic marker in LC patients from the general population. This study assessed ctDNA’s prognostic value in PLHIV from a dedicated phase II trial. Overall, 61 PLHIV with advanced non-squamous non-small-cell lung cancer (NSCLC) participated in the IFCT Phase II trial evaluating first-line four-cycle carboplatin (Ca) AUC5 pemetrexed (P) 500 mg/m2 induction therapy every 3 weeks, followed by P maintenance therapy. Blood samples collected before treatment were analyzed to detect ctDNA using ultra-deep targeted next-generation-sequencing (NGS). Appropriate samples were available from 55 PLVIH and analyzed for ctDNA detection. Including 42 males (76.4 %), 52.9 years median age, 51 smokers (92.7 %), five with non-squamous NSCLC Stage III (9%), 50 Stage IV (91 %), and performance status (PS) 0−2. ctDNA was detected in 35 patients (64 %), 22 with high and 13 with low ctDNA levels.

Human Blood Harbors Cell-Free Microbial DNA

Most biomarkers that clinicians use to diagnose cancer are human. But growing evidence for a link between the microbiome and malignancy presents an opportunity to look at the presence of microbial DNA as a way to identify and possibly predict disease. In a study published June 23 in Genome Biology, researchers demonstrate that it is possible to detect bacterial DNA in blood samples in both healthy people and melanoma patients.
