[A Case of Concentrated Ascites Reinfusion Therapy(CART)for Abundant Refractory Ascites in Cecal Cancer with Peritoneal Dissemination Followed by the Readministration of Chemotherapy].

A 66-year-old man underwent laparoscopic ileocecal resection for cecal cancer with liver metastasis(cT3N1M1a, cStage Ⅳa). One month later, combination chemotherapy with capecitabine, oxaliplatin, and bevacizumab was administered for liver metastasis. However, during the treatment, peritoneal dissemination and abundant diuretic-resistant ascites was revealed, resulting in poor dietary intake. One year and 11 months after the surgery, the chemotherapy was interrupted and cell-free and concentrated ascites reinfusion therapy(CART)was undergone as palliative care. The initial volume of retrieved ascites was 6,500 mL, and the volume was increased gradually to a maximum of 14,020 mL without hemodynamic instability. Totally CART was administered 10 times during 7 months without any complications: mean volume of retrieved ascites; 9,780 mL/unit, the interval between therapies; 2-3 weeks. Serum albumin level did not decrease since CART administration. His oral intake and daily activities were improved by CART. These clinical outcomes contributed to the readministration of chemotherapy. We present a recent case of safe and periodical CART for abundant refractory ascites in cecal cancer with peritoneal dissemination, resulting in the improvement of QOL and the readministration of chemotherapy.
