NBDC Research ID: hum0403.v1
SUMMARY
Aims: To prospectively identify new biomarkers by evaluating gene mutations and microRNA expression using tumor tissues and free nucleic acids collected from patients with urologic cancer.
Methods: Cell-free DNAs extracted from plasma samples were subjected to a circulating tumor DNA analysis using the AVENIO ctDNA Expanded Kit (Roche Diagnostics, Basel, Switzerland). DNA concentration was assessed using a Qubit fluorometer (Thermo Fisher Scientific, Waltham, MA, USA).
Participants/Materials: 16 plasma samples were collected before immune checkpoint inhibitor treatment and 9 plasma samples were collected after immune checkpoint inhibitor treatment from 16 metastatic urothelial carcinoma patients.
