NGS of prostate cancer

Schütz, E. et al. Comparative analysis of the chromosomal origins of circulating nucleic acids in breast and prostate cancer. J ClinOncol 28:15s, 2010 (suppl; abstr 10505).

The aim of this study was to find signature CNA sequences from patients with breast cancer (BCa) or prostate cancer (PCa) compared to healthy controls, with respect to their predictive potential, as well as to provide new insights into tumor biology.

Breast Cancer cfDNA with NGS

Beck, J. et al. Next Generation Sequencing of Serum Circulating Nucleic Acids from Invasive Ductal Breast Cancer Patients Reveals Differences to Healthy and Non-malignant Controls. Mol. Cancer Res. 2010; 8: 385-92.

Circulating nucleic acids (CNA) isolated from serum or plasma are increasingly recognized as biomarkers for cancers.We report specific DNA-transposable element sequences that could discriminate all stages of invasive ductal breast carcinoma with significant specificity and sensitivity.

NGS of cell-free DNA in Healthy Humans

Beck, J. et al. Profile of the circulating DNA in apparently healthy individuals. Clin Chem. 2009; 55: 730-8.

Circulating nucleic acids (CNAs) have been shown to have diagnostic utility in human diseases. The use of mass sequencing and bioinformatics provides the basis for new diagnostic approaches that use CNAs as biomarkers for both malignant and nonmalignant diseases.

NGS of cell-free DNA in animals

Gordon, Paul MK, et al. Disease-specific motifs can be identified in circulating nucleic acids from live elk and cattle infected with transmissible spongiform encephalopathies. Nucleic Acids Research 37.2 (2009): 550-556.

In a 25-month time-course experiment, CNAs were isolated from blood samples of 24 elk (Cervuselaphus) orally challenged with chronic wasting disease (CWD) infectious material.Our results may become useful for the early diagnosis of TSE in live elk and cattle.

Liquid biopsies in predicting and monitoring response to therapy in advanced pancreatic cancer

Madappa N. Kundranda Genomic change index (GCI) and liquid biopsies in predicting and monitoring response to therapy in advanced pancreatic ductal adenocarcinoma (PDAC). J Clin Oncol 33, 2015 (suppl 3; abstr 309).

Advanced PDAC is a lethal disease with dismal 5 year survival. The current modalities for monitoring therapy response using serum (CA) 19-9 levels have poor specificity and radiological responses have long lag times. Tests for rapid and accurate clinical assessment are needed for early decision making.

Prognostic value of cell-free DNA in patients with oropharyngeal cancers.

Julia Beck, Margret Rave-Fraenk, et al. Prognostic value of cell-free DNA in patients with oropharyngeal cancers.J Clin Oncol 34, 2016 (suppl; abstr e17511).

Tumor derived plasma cell-free DNA (TcfDNA) is described as biomarker to monitor tumor burden in cancer. Large somatic genome aberrations are hallmarks of malignancies and detectable in cfDNA. However, levels of TcfDNA are variable according to cancer types. We obtained copy-number instability (CNI) scores of cfDNA in treatment-naïve head and neck cancers before and after therapy.
