Clinical Trials in CRS and HIPEC: Ongoing Trials and Future Directives

Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) have gained momentum as a viable treatment option for primary or recurrent malignancies with peritoneal metastasis (PM). Despite significant progress over the last 30 years, this field has lacked in high-quality randomized, controlled trials, with most data supporting the use of CRS and HIPEC coming from smaller retrospective and prospective trials. Ultimately, validation of treatment efficacy and outcomes will require large, collaborative, well-organized, outcomes-based studies. Thus far, the use of CRS and HIPEC in metastatic gastric, ovarian, pancreatic, and other gastrointestinal malignancies has spurred further development of a growing number of prospective clinical trials to study outcomes and survival benefit. This chapter summarizes some of the notable, completed clinical trials and current trials being conducted.
