Ovarian Epithelial Cancer clinical trials

Preoperative Ascites Drainage Versus Standard Care for Patients With Advanced Ovarian Cancer

Patients with significant ascites and advanced ovarian cancer (AOC), undergoing complex, cytoreductive surgery are at risk of malnutrition, poor quality of life and the risk of hypo- or hypervolemia in a perioperative period. All these factors may cause hemodynamic consequences during anesthesia and surgery, and elevate the risk of morbidity and mortality. The objective of the study is to evaluate, whether slow ascites evacuation for a few days before the surgery for AOC, could 1) influence the hemodynamic consequences of ascites on systemic circulation in patients undergoing surgery, 2) improve patient's quality of life and 3) ability to feed correctly before treatment starts, and thus lower the risk of perioperative morbidity. Eligible patients are those with significant ascites, diagnosed or suspected for AOC, who are scheduled for primary surgery (both upfront cytoreduction or laparoscopic evaluation before neoadjuvant chemotherapy), that cannot be performed within next 7 or more days, for any reason. Patients will be asked to fill in quality of life questionnaire (QLQ). Clinical data, a Subjective Global Assessment (SGA) will be recorded. Patients will be randomized to either intervention arm A - insertion of vascular catheter into abdominal cavity and slow, systematic, daily ascites evacuation, or to observation arm B - standard of care with just observation (acute large volume (>5000ml) paracentesis allowed if needed). Patients in both groups will be encouraged to use oral nutritional support. Randomization will be open, 1:1, for every eligible, consecutive patient. After 7 days patients will be interviewed, asked to fill in QLQ, patient's experience on the treatment survey, a SGA will be recorded. During the first hour of the surgery hemodynamic data from anethetic charts will be recorded along with other clinical data concerning patient's characteristics, surgery details and 30-day postoperative follow-up. A template is provided. The hypothesis of the study is that slow, systematic ascites evacuation few days before surgery for advanced ovarian cancer can facilitate hemodynamic control of systemic circulation of patients undergoing surgery, and improve patients' quality of life, feeding ability before treatment starts. Secondary we would expect lower risk of perioperative morbidity and mortality.
