We propose that, at the primary location, OC cells can release specific cytokines (i.e., IL-6, IL-8, IL-1β, G-CSF, GROα, MCP-1, and TNFα) to the tumor environment (i.e., peritoneal fluid) which may attract neutrophils to pro-metastatic niches (for instance, omentum) to induce NETosis. The gene discussed is IL6; the disease is neoplasm.
