Is cancer a systemic disease? Does regional nodal metastases instigate distant metastasis or promote failure at the primary site? These are just two of the issues discussed in this new volume based on the results of a symposium on the diagnosis, significance and treatment of occult regional nodal metastases in the most common types of cancer. Occult Nodal Metastasis in Solid Carcinomata presents material for all levels of interest–from basic science to clinical application, and will be of practical use to medical libraries, oncologists, radiologists, clinical pathologists, immunologists, and cell and molecular biologists.
