FOLFOX as a therapeutic option in patients with hepatic failure due to liver metastasis of gastrointestinal (GI) system malignancies: A case series.

Abstract

e16378 Background: The treatment options for patients with hepatic metastasis presenting with liver dysfunction, particularly those experiencing severe hyperbilirubinemia, are limited. The oxaliplatin and fluorouracil/folinic acid regimen, known as FOLFOX, stands out as a viable option based on its pharmacokinetics. However, clinical data regarding the specific dosage and tolerability of this regimen are limited, and clear recommendations are not currently available. Patients and Methods: Patients who presented with severe hyperbilirubinemia immediately after the diagnosis of GI adeno cancer, and who were not eligible for drainage options, were prospectively observed in our clinic in Turkey throughout the year 2023. Severe hyperbilirubinemia was defined as a bilirubin level > 5mg/dL. The FOLFOX regimen was administered every two weeks, and the fluorouracil dose was initially reduced by 50% for the first two cycles. Subsequently, the dose was increased to the total amount if no toxicity occurred. Results: Six cases of GI cancer patients meeting the criteria were identified. Subsequent laboratory data for these six patients were collected after initiating the FOLFOX regimen. All six patients underwent the FOLFOX regimen with dose reduction for the first two cycles. Following the first cycle of chemotherapy, bilirubin levels dropped and normalized (Table 1), leading to an improvement in the patients' clinical condition. Conclusions: While our series is limited by a small number of patients, treatment with FOLFOX has proven to be feasible and may yield significant benefits in patients with severe liver dysfunction caused by GI cancer, especially when no further drainage options are available.
