title: [Reversible liver steatosis in patients treated with 5-fluorouracil and interferon-alpha].
abstract: Twenty-three patients with metastatic colorectal carcinoma were randomized as part of two multicenter Phase III trials to receive either 5-fluorouracil (5-FU)/interferon alpha-2A (INF-alpha) or 5-FU +/- leucovorin. The patients were evaluated regularly for response by CT of the abdomen when treatment began and then every six to eight weeks. incidentally, we found that four of 13 patients treated with 5-FU/INF-alpha and none of ten patients treated with 5-FU +/- leucovorin developed hepatic steatosis during treatment. The diagnoses were based on a decreased CT value of the liver parenchyma by the repeated CT, and histologically verified by liver biopsies. There was no relationship to cumulative 5-FU or INF-alpha dose. Based on posttreatment CT, the liver parenchyma changes were reversible after therapy was stopped. Recognition of this condition in patients receiving 5FU/INF-alpha is important to prevent a patient from being labeled as having progressive hepatic metastases.
