“…Direct cancer cell infiltration from the primary tumor to the hernia mesh has been reported as a possible cause, especially for colon cancer exposed to the peritoneum 4,6 . Moreover, floating malignant tumor cell implantation is considered a cause of metastasis to the hernia repair mesh 5,7 . In addition, some inflammatory cytokines and growth factors such as interleukin-1 beta, interleukin-6), tumor necrosis factor-alpha, epidermal growth factor, basic fibroblast growth factor, heparin-binding epidermal growth factor–like growth factor, and 2 spliced variants of vascular endothelial-derived growth factor contribute to cancer cell implantation, adhesion, and growth at the hernia repair site.…”
