Official Title: Retrospective Analysis of Patients Treated With Bevacizumab in GHPSJ Intraperitoneal for the Treatment of Refractory Malignant Ascites
Brief Summary:
The refractory malignant ascites is a complication of advanced stages of many cancer types. It is characterized clinically by abdominal pressure sensation, shortness of breath and pelvic pain. Thus, it contributes to decreased quality of life for these patients in palliative care.
Conventional treatment is based on paracentesis of ascites. The progression of the disease leads to increased production of ascites requiring more frequent paracentesis. Main therapeutic alternatives are constituted by the controversial use of diuretics and the use of an antibody inhibiting the activity of the Vascular Endothelial Growth Factor (VEGF): bevacizumab. Catumaxomab, a monoclonal antibody anti-EpCAM and CD3, developed for the treatment of refractory malignant ascites showed no sufficient clinical benefit.
VEGF is overexpressed in many tumors. VEGF causes an increase in capillary permeability and capillary filtration surface generating increased protein extravasation. These phenomena are responsible for an increase of the volume of ascites product. Thus the use of inhibitors of VEGF, such as bevacizumab, could reduce the production of ascites.
The efficacy of bevacizumab to decrease the volume of ascites product was demonstrated on small animals in intraperitoneal administration.
Studies in humans are few and the doses used are not consistent from one study to another.
Detailed Summary:
Main objective / secondary:
The objective of this study is to describe the population, adverse effects, the volume of ascites product and time between paracentesis in patients receiving bevacizumab in intraperitoneal through a refractory malignant ascites.
