This volume has been conceived to provide different approaches used to overcome resistance through the use of chemo or immunosensitizing agents, used in combination with cytotoxic drugs. This volume has been divided arbitrarily into two sections, namely, chemosensitization and immunosensitization. Chemosensitization refers to the use of sensitizing agents that can reverse resistance to chemotherapeutic drugs. Immunosensitization refers to agents that can sensitize tumor cells through cytotoxic mechanisms mediated by host immune cells and/or corresponding cytotoxic factors. The authors in this volume are well established investigators in the field of sensitization and represent expertise in novel approaches used for sensitization. This volume is by no means all inclusive and primarily represents some examples that have been selected for reference.
