TY - JOUR T1 - The Evaluation of Thermal Cisplatin Sensitization in Normal and XP Human Cells Using Mild Hyperthermia at 40 and 41 °C JF - Anticancer Research JO - Anticancer Res SP - 2649 LP - 2653 VL - 25 IS - 4 AU - G.P.

While mild hyperthermia itself for up to 6 hours showed little to no toxic effects, it did result in significant sensitization of response to cisplatin treatment. Sensitization for the normal and mutant cell line was comparable, indicating that nucleotide excision repair (NER) probably does not have a role in this process. For the 41 °C heating, thermotolerance developed and heating times greater than 4 hours resulted in protective effects from cisplatin cytotoxicity. This was not observed for heating at 40 °C for up to 6 hours. Copyright© 2005 International Institute of Anticancer Research (Dr. John G. Delinassios), All rights reserved ER -
