The Chicago Consensus on Peritoneal Surface Malignancies: Methodology.

The Chicago Consensus Working Group provides multidisciplinary recommendations for the management of peritoneal surface malignancies of various causes. These guidelines are developed with input from leading experts including surgical oncologists, medical oncologists, pathologists, radiologists, palliative care physicians, and pharmacists. These guidelines recognize and address the emerging need for increased awareness of the appropriate management of peritoneal surface disease. They are not intended to replace the quest for higher levels of evidence. This article explains the process and methodology of building these guidelines and pathways.
