The Tumor Microenvironment

This book explores the many biological and physical aspects of the tumor microenvironment. It represents a superb compilation of the latest thoughts and data on this topic, and the in-depth chapters are written by known professionals in the field. This book will explore the many biological and physical aspects of the tumor microenvironment. The book will include chapters on the various cells that influence tumor growth and function as well as the cell-associated and soluble proteins that can promote invasion and metastasis. Several chapters will describe endothelial cells and pericytes that form tumor vasculature. Insights on the role of progenitor and stem cells will be included. The contribution of the supporting stroma will be addressed in addition to cell-cell signaling and cell-matrix interactions. Additional chapters will describe the influence of infiltrating cells of the immune system on tumor growth.

The fact that tumors are composed of both tumor cells and host cells has long been known. These tumor-associated cells include vascular endothelial cells and pe- cytes, as well as inflammatory cells such as neutrophils, monocytes, macrophages, mast cells and eosinophils, and lymphocytes. The tumor cells also interact with stromal cells and with elements of the tissue extracellular matrix. What has been less appreciated is the role that these cells could have in modulating the growth, invasion, and metastasis of the tumor. Early on, the elements of what we now call the tumor microenvironment were considered to be more or less innocent bysta- ers to the role of the tumor cells as they grew and invaded local sites. Today, there is an increased understanding of the critical role of the tumor microenvironment as dramatically influencing the course of tumor development and dissemination. This volume represents a superb compilation of the latest thoughts and data regarding the role of each essential component of the tumor microenvironment in cancer development and progression. Perhaps, the earliest recognition of the role of nonmalignant cells as cancer re- lators was the recognition that lymphocytes can participate in what was termed immune surveillance in the 1960s. Our understanding of tumor immunity has improved markedly since then, and there are now successful clinical studies sh- ing the potential use of immune-based therapies in cancer treatment.

Klappentext
The field of cancer biology and developmental therapeutics is continually evolving as new methodologies are developed and new targets are discovered. Although multiple therapeutics directly target the malignant cells these drugs rarely prevent recurrence of disease or the progression of metastasis. The complex biology of tumors presents challenges in designing treatments that will eliminate the malignant cells as well as the supporting network of vasculature and stroma that allows for the comparison of tumors to developing organs in embryos. In addition to blood vessels and malignant cells, tumors consist of fibroblasts, immune and inflammatory cells, and a myriad of proteins that comprise the extracellular matrix. Effective eradication of malignant disease requires therapeutic strategies that factor in targeting the tumor microenvironment. In the past decade, a new class of anticancer drugs has emerged that interferes with tumor angiogenesis; however the clinical benefit from treatment with the first generation antiangiogenic agents added to the standard of care is often modest. Thus, there remains a critical need to understand the tumor microenvironment and to develop anti-cancer therapies that address this aspect of malignant disease. The first edition of The Tumor Microenvironment is intended to give a current perspective on the role of the tumor microenvironment in malignant progression and detail strategies for novel therapies directed towards the cellular matrix. This book explores the many biological and physiological aspects of the tumor as a tissue and includes chapters on the variety of cells that influence tumor growth and spread as well as the cell-associated and soluble proteins that can promote invasion and metastasis. Several chapters describe endothelial cells and pericytes that form tumor vasculature. Insights into the role of progenitor and stem cells are included. The contribution of the supporting stroma is addressed in addition to cell-cell signaling and cell-matrix interactions. Additional chapters describe the influence of infiltrating cells of the immune system on tumor growth. The Tumor Microenvironment is the definitive text detailing cutting edge research by experts in the field and will be a valued resource in the study of this important area of cancer biology for many years to come.
