ATLANTIS: Malignant Ascites in Ovarian Cancer: Impact of Total Paracentesis on Hemodynamics
Study Details
Study Description
Brief Summary
The ATLANTIS-study was designed to determine the safety of a full paracentesis in patients with malignant ascites due to ovarian cancer. The underlying hypothesis states, that full paracentesis does not impair safety, compared to fractioned paracentesis with clamping of the drain. Half of the patients will receive a full paracentesis, while the other half will receive fractioned paracentesis with clamping of the drain after 3 liters of ascites was evacuated. All patients receive extensive monitoring of hemodynamics and kidney function.

Detailed Description
Background: Malignant ascites is common in ovarian cancer and often causes symptoms such as abdominal pressure and shortness of breath, resulting in an decreased quality of life for the patient. Paracentesis is a safe and easy method for symptom relief. But no guidelines exist on the management of ascites drainage in ovarian cancer. In many cases a partial paracentesis is performed, due to fear of hemodynamic instability or kidney failure, with partial drainage of the intraperitoneal fluid on the first day and subsequent drainage on the next day. As there is no study that reported a deteriorated health due to full paracentesis in ovarian cancer, the decision whether a partial or total paracentesis is performed depends entirely on the department or the physician.
Since a total paracentesis can be performed as an out-patient treatment, this approach is often preferred by the patient. Full paracentesis is also more efficient and cost-effective.
The objective of the ATLANTIS-study is to prove the safety of total paracentesis regarding hemodynamic changes and kidney failure.
Methods: ATLANTIS is a randomized, prospective, clinical study that aims to include 60 patients. Patients with histologically confirmed epithelial ovarian, fallopian tube and peritoneal cancer are randomized into two arms: Partial (3 Liter) and total paracentesis. Before, during and for two hours after the paracentesis, an advanced hemodynamic monitoring is performed to ensure the patients' safety. The monitoring includes mean arterial pressure and stroke volume. After the initial phase of extensive monitoring (2 hours), the blood pressure is measured for a period of 24 hours to evaluate not only short term, but also long-term hemodynamic changes. Before and 24 hours after the paracentesis, blood samples are analyzed to detect a potential acute kidney failure.

Outcome Measures
Primary Outcome Measures
- Change of stroke volume [20 minutes prior to paracentesis, during paracentesis up to the end of paracentesis, an average of 50 minutes]
Stroke volume is measured by advanced hemodynamic monitoring
- Change of mean arterial pressure [20 minutes prior to paracentesis, during paracentesis up to the end of paracentesis, an average of 50 minutes]
Mean arterial pressure is measured by advanced hemodynamic monitoring
Secondary Outcome Measures
- Incidence of side effects in the post-paracentesis interval [24 hours after the finish of the paracentesis]
Incidence of hypotension (medical intervention indicated) and impairment of kidney function (KIDIGO criteria)
- Incidence of symptoms in the post-paracentesis interval [24 hours after the finish of the paracentesis]
Incidence of hypotension (medical intervention indicated) and impairment of kidney function (KIDIGO criteria)
- Change of stroke volume in the post-paracentesis interval [2 hours after the finish of the paracentesis]
Stroke volume is measured by advanced hemodynamic monitoring
- Change of mean arterial pressure in the post-paracentesis interval [2 hours after the finish of the paracentesis]
Mean arterial pressure is measured by advanced hemodynamic monitoring
- Change of laboratory values [Serial measurements: 2 hours prior to paracentesis, 24 hours after paracentesis]
Measurement in plasma (Blood count, creatinin, AST, ALT, urea, aldosterone, renin, sodium, potassium, albumin, C-reactive protein, leukocytes)
- Urine excretion [24 hours after the finish of paracentesis]
Urin volume
- Quality of life- pre and post paracentesis: EQ-5D questionnaire [2 hours before paracentesis, 24 hours after paracentesis and 1 week after paracentesis]
Measured with the EuroQuol-Group 5 Dimensions - Visual analog scale (EQ-5D VAS) questionnaire, the questionnaire directs to characterize the quality of life by mobility, activities, pain and fear and subjective scale between 1 (worst) and 100 (best)
- Ascites related symptoms- pre and post paracentesis [2 hs before paracentesis, 24-hours after paracentesis and 1 week after paracentesis]
Measured with the and Functional Assessment of Chronic Illness Therapy-Ascites Index (FACIT-AI) questionnaire, the questionnaire directs to characterise the symptoms associated to ascites regarding 13 factors e.g. appetite, sleep, activities, symptoms, emotional distress by 0 to 4 points. The maximum score is 52 (best result: 13x4), 0 is the minimum score (worst result 13x0)
- Measurement of exact drainage volume [Within 1 hour after the finish of paracentesis]
Measurement of exact drainage volume in millilitre
- VEGF (vascular endothelial growth factor) level [Within 1 hour after the finish of paracentesis]
Measurement of the concentration of hormone vascular endothelial growth factor in ascites
- Change of venous return and mean systemic filling pressure [20 minutes prior to paracentesis, during paracentesis up to the end of paracentesis, an average of 50 minutes]
Venous return and mean systemic filling pressure is measured by advanced hemodynamic monitoring
