AbstractBackground: Malignant ascites (MA) represents 10% of all causes of ascites and is associated with a poor prognosis. The PleurX tunneled peritoneal catheter is a device that allows the management of MA at home in a palliative care context (renamed AscitX catheter for this work). The objective of this study was to analyze real-world data of AscitX use for cancer patients with MA, to describe complications associated with the insertion of this device, and to identify factors influencing patient outcomes. Methods: Fifty-six patients with AscitX catheter insertion between October 2018 and October 2022 in our comprehensive cancer center were retrospectively analyzed. Computed tomography (CT) scans were reviewed by two radiologists to determine the presence of liver and peritoneal metastases and to identify portal hypertension. Results: The majority of patients were followed for pancreatic cancer (39%), followed by ovarian cancer (18%). We identified four cases of severe infections post-insertion and two moderate infections. The median survival time after AscitX insertion was 18 days. A Kaplan-Meier analysis did not identify differences in survival time between patients with peritoneal metastases and those with liver metastases. In contrast, CT-diagnosed portal hypertension and the absence of diuretic treatment were independently associated with a better prognosis. Regarding post-catheter end-of-life management, 41% of the patients died at home. Conclusions: AscitX catheter safety appears to be acceptable and most of the palliative care patients included in our study died at home. We identified CT-diagnosed portal hypertension as associated with better prognosis, as well as the absence of diuretic treatment.
