Peritoneal malignancy is a rapidly growing field within surgical oncology. National and International treatment programmes and training curricula are being established worldwide to co-ordinate treatment and management of these challenging clinical problems. A large body of evidence now exists, but the practical implications of this evidence base remain unclear. The Peritoneal Malignancy Institute in Basingstoke, the largest centre in the world, is at the forefront of new developments and techniques. This manual combines the experience of the PMI with the latest evidence to provide a practice-oriented guide to the successful set up and running of a peritoneal malignancy unit.
