Abstract
In an aspect, a method for detecting the presence or absence of cancer in a subject comprises: (a) obtaining samples from the subject from different time points, wherein a first sample obtained at first time point is a polynucleotide sample from a tumor tissue specimen and a second sample obtained at second time point is a cell-free polynucleotide sample from a blood sample; (b) processing polynucleotides from each of the samples, comprising: i) tagging at least a portion of the polynucleotides, thereby generating tagged parent polynucleotides; ii) amplifying at least a portion of the tagged parent polynucleotides to generate progeny polynucleotides; iii) enriching at least a portion of the progeny polynucleotides for target genomic regions; thereby generating enriched polynucleotides; and iv) sequencing at least a portion of the enriched polynucleotides to generate sequencing reads; and (c) analyzing genomic regions for at least one epigenetic feature from the sequencing reads.
