Hyperthermic intraperitoneal chemotherapy as palliative treatment for malignant ascites A single-center experience and a review of the literature.

Malignant ascites is an abnormal accumulation of fluid in the peritoneal cavity of patients with intraperitoneal cancer dissemination. This clinical condition could represent the terminal evolution of a lethal disease and could influence the prognosis, severely impairing the patients' quality of life. Treatment options include a multitude of different procedures with limited efficacy and some degree of risk; diuretics, paracentesis, peritoneo-venous shunts and intraperitoneal biologic agents like anti-VEGF molecules, metalloproteinase inhibitors and immunomodulators are included. None of these approaches have been established as a standard of care because of their low efficacy or severe side effects. The last two decades saw the emergence of cytoreductive surgery with hyperthermic intraperitoneal perioperative chemotherapy (HIPEC) as a viable therapeutic approach resulting in an effective cure against refractory malignant ascites. The following describes our experiences with 3 cases together with a literature review.
