Neutrophils are mobilized to peritoneal cavity in some patients with ovarian cancer dissemination; however, its pathological significance remains unknown. This study aimed to investigate the role of neutrophil extracellular traps (NETs) in ovarian cancer dissemination. We conducted a retrospective analysis of clinical data and samples from 340 patients with ovarian cancer who underwent primary surgery between 2007 and 2016 at the Osaka University Hospital. In vitro, NETs formation was induced by stimulating human peripheral neutrophils. The human ovarian cancer cell line, OVCAR8, was cocultured with NETs. For an ovarian cancer dissemination mouse model, we performed an intraperitoneal injection of OVCAR8 cells into nude mice. The association between NETs and peritoneal dissemination was explored, and model mice were treated with the PAD4 inhibitor GSK484 to assess antitumor efficacy. Neutrophilia (neutrophil count &amp;gt;7000\/mm3) correlated with shorter survival, advanced peritoneal dissemination, elevated granulocyte colony-stimulating factor (G-CSF) levels, increased neutrophil count in ascites, and augmented NETs foci in peritoneal dissemination sites. In vitro assays revealed that G-CSF stimulated neutrophils to form NETs, promoting cancer cell adhesion. In vivo investigations revealed that G-CSF\u2013producing tumor-bearing mice had accelerated peritoneal dissemination and poor prognosis. NETs formation was pathologically observed at the peritoneal dissemination sites. Inhibition of NETs formation by GSK484 significantly delayed peritoneal dissemination in vivo. In conclusion, G-CSF was associated with intra-abdominal NETs formation and increased peritoneal dissemination. NETs represent potential therapeutic targets for ovarian cancer, particularly in patients with neutrophilia.<\/jats:p>","DOI":"10.1093\/jleuko\/qiae166","type":"journal-article","created":{"date-parts":[[2024,7,31]],"date-time":"2024-07-31T21:43:25Z","timestamp":1722462205000},"page":"1157-1168","source":"Crossref","is-referenced-by-count":27,"title":["G-CSF
