Pegram, Alena A. Chekmasova, Gavin H. Imperato and Renier J. Brentjens Preface Suddenly we heard a voice crying, "This is the sea. This is the deep sea. This is the vast and mighty sea." And when we reached the voice it was a man whose back was turned to the sea, and at his ear he held a shell, listening to its murmur” Khalil Gibran – The Madman For decades we have been learning about the interplay between tumors and the immune system. Our knowledge seemed somewhat incomplete and indirect, like listening to the ocean waves through a shell. Only recently, cancer immunotherapy has started to become a reality, with Provenge (Dendreon Corporation, WA), an autologous antigen-presenting cell preparation, earning the approval of United States Food and Drug Administration (FDA) for the treatment of advanced prostate cancer in 2010. This book provides an excellent review of the field of cancer immunotherapy, with special focus on prostate cancer, one of the most common cancers and a leading cause of cancer deaths in industrialized countries. The directions of immunotherapy of melanomas are also dicsussed in some detail within this book. Several chapters are dedicated to novel immunotherapeutic approaches utilizing the immunostimulatory functions of cell-based and protein-based vaccines, Toll-like receptors, Glycosphingolipids, Stress molecules, Type III Interferons, Interleukin 12 and biological plant-based compounds such as Triterpenes. I would like to thank the people who helped with this publication, especially Ms Petra Nenadic. Finally, I dedicate this book to my family, my mentors and mentees throughout my career.
