Soft tissue tumors (STTs) are frequently misdiagnosed in inexperienced hands. Having diagnosed and treated hundreds of patients with these difficult tumors in the last few years, Institut Curie physicians have collected core data contributing to breakthrough research into the morphological, biological, and molecular aspects of soft tissue tumors, resulting in valuable translational and clinical applications to patient treatment. Soft Tissue Tumors: A Multidisciplinary, Decisional Diagnostic Approach presents a distillation of these experiences, combined with valuable data and perspectives contributed by senior pathologists, oncologists, and radiologists from several of the world’s other leading cancer centers of excellence.
