Abstract: Abstract: Tumor lysis syndrome (TLS) is the rapid dissolution of tumor cells and cell contents, and its metabolite is rapidly released into the blood, causing a series of complications such as high uric acid, high potassium, high phosphorus,hypocalcemia and acute renal insufficiency. TLS is commonly seen in patients with rapidly growing malignant tumors that are sensitive to chemotherapy, and which is rare in solid tumors. We found one case of primary liver cancer with acute TLS, who was given hemodialysis to protect the liver and symptomatic treatment, and the patient is on the mend.

Key words: liver neoplasms, postoperative complications, tumor lysis syndrome, transcatheter arterial chemoembolization, extracorporeal dialysis
