Overview of the methods for sample collection and sequencing. (A) Tumor samples from biopsy were obtained at baseline (T0). Blood samples were obtained at baseline (T0), Cycle 1 Day 3 (T1), at time of surgery (T2), during follow-up (T3- every 3–6 month intervals for 5 years), and during relapse (T4). (B) Baseline tumor samples were subjected to whole exome sequencing (WES) and variants were identified to build a custom micro-panel. All blood samples (T0–T4) were assessed using the amplicon based custom micro-panel. C. Sequencing was subjected to unique molecular identifier (UMI) based error correction. Variant allele fractions (VAFs) were ascertained for baseline biopsies and ctDNA blood samples at all timepoints.
