7.1 Definitions for adverse event reporting Adverse event (AE) assessment, data collection and reporting will be done to ensure the safety of patients enrolled in this study. Adverse events secondary to both cytoreductive surgery and the utilization of intraperitoneal chemotherapy will be monitored closely, recorded appropriately and reported as required. The descriptions and grading scales found in the revised NCI Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 will be utilized for AE reporting. All appropriate treatment areas should have access to a copy of the CTCAE version 4.0. A copy of the CTCAE version 4.0 can be downloaded from the Cancer Therapy Evaluation Program (CTEP) web site (http://ctep.cancer.gov).
