Core Tip

Core tip: Hyperthermal intraperitoneal chemotherapy is widely used as a standard treatment option for peritoneum invading gastrointestinal cancer. Our in vitro results suggest that optimal temperature has to be taken into consideration for achieving optimal therapeutic effect. In addition to cisplatin, hyperthermia up to 43 °C does not affect the viability of AGS, Caco-2, and T3M4 cells in a synergistic manner. However, some regimens of hyperthermia and cisplatin treatment are beneficial regarding an increase in intracellular cisplatin concentration and enhancement apoptosis of gastrointestinal cancer cells.
