Abstract

This data article subsumes the data acquiration process, analysis and results of 'Circulating tumor DNA correlates with tumor burden and predicts outcome in pancreatic cancer irrespective of tumor stage' published in European Journal of Surgical Oncology (Eur J Surg Oncol. 2021 Dec 1:S0748-7983(21)00947-1. doi:10.1016/j.ejso.2021.11.138. PMID: 34876329) (Kirchweger et al., 2021). 28.5 mL of blood was obtained from 60 patients with localized pancreatic cancer directly prior to curative intended surgery as well as from 47 patients with metastasized pancreatic cancer (PDAC) directly prior to palliative intended systemic treatment initiation. Cell-free DNA preparation was done on the Chemagic 360 (Perkin Elmer, Waltham, Massachusetts, USA) using the kits CMG-1304 and CMG-844 from the same provider and quantified using the Quantus fluorometer (Promega, Madison, Wisconsin, USA). Screening for most common KRAS alterations (KRAS G12/G13 screening kit and additionally for KRAS Q61 if screening was negative) was performed utilizing the QX200™ Droplet Digital™ PCR System from Bio-Rad (Bio-Rad Laboratories, Hercules, CA, USA). Volumetric analysis was performed on contrast enhanced dual-energy CT scans in the arterial and portal venous phase prior to treatment initiation using Syngo.via (Siemens Healthcare, Forchheim, Germany) on MM Oncology Workflow adhering to RECIST 1.1 criteria (Eisenhauer et al., 2009). CtDNA predicts outcome in localized and disseminated disease. Moreover, it correlates with distant metastasis volume and positive lymph nodes but not primary tumor volume and therefore could indicate subclinical synchronous distant metastases in localized PDAC undetectable by current gold standard (computed tomography).
