Popis: Background. Thirty previously untreated patients with metastatic colorectal carcinoma were randomized as part of two multicenter Phase III trials. Twenty-two patients were randomized to receive either 5-fluorouracil (5-FU)/interferon alfa-2A (IFN-α) or 5-FU/leucovorin (11 patients in each arm). Eight patients were randomized to receive 5-FU/IFN-α or 5-FU alone (4 patients in each arm). Methods. Twenty-three patients (13 patients treated with 5-FU/IFN-α and 10 patients treated with 5-FU/leucovorin or 5-FU alone) were evaluated regularly for response by computed tomography (CT) scans of the abdomen when treatment began and then every 6-8 weeks. Results. Incidentally, four patients developed hepatic steatosis during treatment with IFN-α and 5-FU. The diagnosis was based on a decreased CT value of the liver parenchyma by repeated CT scans of the abdomen during treatment, and this diagnosis was verified histologically by liver biopsy. There was no relationship to cumulative IFN-α or 5-FU dose. Based on posttreatment CT scans, the liver parenchyma changes were reversible after therapy was stopped, and there were no significant clinical sequelae. No patients treated with 5-FU/leucovorin or 5-FU alone experienced a decreased CT value of the liver parenchyma. Conclusion. Hepatic steatosis was been observed in approximately 30% of patients treated with IFN-α and 5-FU. The hepatic changes were fully reversible after the treatment was stopped. Recognition of this condition is important to prevent a patient from being labeled as having progressive hepatic metastases. Cancer 1995 ;75 : 2592-6.
