Rinsing of the belly cavity with heated chemotherapy is designed to kill peritoneal cancer tumor homes that are invisible to the naked eye and are left behind after resection of the tumor. Chemotherapy poured into the cavity of the stomach, enters very little in the rest of the body and causes far fewer side effects than the same amount of chemotherapy given via intravenous infusion. In this way, we can deliver much larger quantities and thus exposing the tumor cells at concentrations that are up to 100 times higher than via an infusion.
If in addition the drug is heated, it increases the destructive effect on tumor cells and the depth of penetration in the remaining homes.
