Blood borne biomarkers, such as secreted proteins, circulating tumor DNA
(ctDNA) and circulating tumor cell (CTC), have garnered much attention
as minimally invasive cancer biomarkers for the “liquid biopsy” of
tumors over the past decade. In this talk, we will describe three
magnetic-nanoparticle-based diagnostic tools that have been used to
assess cancer in peripheral blood successfully: 1) Stanford spin-off
MagArray Inc. has launched REVEAL, a cancer-specific blood test that may
aid clinicians in characterizing indeterminate pulmonary nodules
(4-30mm) in current smokers aged 25-85. The REVEAL Score is calculated
using an algorithm based on the measurement of 3 clinical factors and 3
blood proteins associated with the presence of lung cancer. The assay is
optimized to rule out lung cancer with a negative predictive value
(NPV) of = 95%. 2) We have developed sequence-specific capture of
hypermethylated or mutated genes of interest from cfDNA for early
detection of NSCLC and colorectal cancer (CRC). With downstream analysis
of PCR products on giant magnetoresistive (GMR) biosensors and
high-resolution melt analysis for a highly multiplexable assay, we have
achieved a sensitivity of 0.01% mutant/methylated allele fractions. Our
optimized assay has the ability to detect down to 16 pg (~4 genome
equivalents) of hypermethylated DNA spiked-in to 3.5 mL of plasma. 3) We
have utilized the MagSifter and immunocytochemistry combined with
automated image analysis and machine learning techniques (random forest,
transfer learning) for the enumeration and diagnosis/prognosis of NSCLC
derived CTCs in patient samples, which are well suited for therapy
selection and monitoring.
