This is a new edition of the original text of the same name, by Das Gupta, published in 1983. Since then, much has happened to expand the knowledge base with regard to both soft-tissue conditions and their treatment. The current edition is not merely an updated text; it has been substantially revised and reworked with new material and the addition of many new authors. Soft-tissue sarcoma represents a small fraction of the entire spectrum of cancers, and only a few texts cover this entity exclusively. Often, it is lumped together with other topics in books focusing on the broader subjects of musculoskeletal tumors and general oncology, resulting in only brief, superficial coverage. Several of the existing texts that are devoted exclusively to soft-tissue tumors are already highly regarded; however, these consist mainly of comprehensive pathology texts and radiographic and surgical atlases. This book is unique in that it fills a niche by bridging the gap between the basic pathology and the clinical treatment of these tumors. Therefore, it will be most useful to clinicians as a reference for making treatment decisions. No other comprehensive text within the field fulfills this need as effectively.
