Abstract
Malignant ascites due to peritoneal metastasis is one of the major problems caused by advanced gastrointestinal cancer. Although drainage of a large amount of ascitic fluid improves symptoms such as abdominal fullness, it may lead to protein loss and renal dysfunction. Cell‑free and concentrated ascites reinfusion therapy (CART) may help avoid such complications due to paracentesis. The purpose of this study was to evaluate the safety of CART. We performed a total of 51 sessions of CART in 5 patients, 4 of whom had gastric cancer and 1 appendiceal cancer. We retrospectively evaluated laboratory data immediately prior to CART, on the following day, 1 week later and 2 weeks later. We also measured the amount of total protein and albumin in collected and concentrated ascites. The mean amount of collected ascites was 4,007 ml. All the patients exhibited improvement of symptoms such as abdominal fullness. Four patients developed fever (>38˚C) immediately after reinfusion of the concentrated ascites and 3 of these patients required corticosteroid administration. The mean total protein and albumin in the collected ascites were 122 and 64 g, respectively, and those in the concentrated ascites 75 and 39 g, respectively. The serum levels of total protein, albumin and creatinine after CART were almost identical to those prior to CART. Blood hemoglobin concentration was significantly decreased 1 day after CART and returned to baseline levels in 1‑2 weeks. CART does not cause renal dysfunction and does not decrease serum albumin; therefore, repeated CART is safe and may be used to improve the symptoms of malignant ascites from gastrointestinal cancer.
