Abstract

The efficacy of next‑generation sequencing (NGS) of tumor‑derived DNA from intraoperative peritoneal washing fluid (IPWF) of patients with pancreatic ductal adenocarcinoma (PDAC) who intend to undergo curative resection remains unclear. The aim of the present study was to evaluate whether genomic mutations in tumor‑derived DNA from IPWF samples of patients with PDAC who intend to undergo curative resection could be detected using NGS. A total of 12 such patients were included in this study. Cytology of IPWF (CY) was assessed and NGS of genomic tumor‑derived DNA from the IPWF was performed to determine whether genomic mutations could be detected in these patient samples. A total of 2 patients (16.7%) had a CY(+) status and 1 patient (8.3%) showed intraoperative macro‑peritoneal dissemination; 11 patients underwent radical surgery. Actionable gene alterations were detected in 8 (80.0%) out of the 10 patients with CY(‑) status based on NGS of IPWF samples, and 3 (37.5%) patients among those with actionable gene mutations identified from IPWF samples underwent peritoneal dissemination after surgery within ~12 months. The most common genomic mutation was in KRAS (9 patients, 75.0%), followed by TP53 (3 patients, 25.0%), SMAD4 (1 patient, 8.3%) and CDKN2A (1 patient, 8.3%). These findings indicated that the genomic mutations identified in tumor‑derived DNA from IPWF samples of patients with PDAC with a CY(‑) status who intend to undergo curative resection are potential biomarkers for predicting the recurrence of early peritoneal dissemination.
