Abstract
Background: This phase II trial investigated the efficacy and safety of oxaliplatin (O), 5-fluorouracil (5-FU), and folinic acid (FA) (OFF) as second-line treatment for patients with metastatic pancreatic adenocarcinoma after failure of first-line gemcitabine treatment. Patients and Methods: 37 patients with confirmed progressive disease on gemcitabine therapy were treated with OFF (O 85 mg/m<sup>2</sup> days 8, 22; FA 500 mg/m<sup>2</sup>, followed by 5-FU 2,600mg/m<sup>2</sup> days 1, 8, 15, 22) every 6 weeks. Patients were treated on an outpatient basis and remained on treatment until disease progression. Results: All patients were assessable for toxicity and effectiveness. We observed moderate hematotoxicity, the most common non-hematologic toxicity was neurotoxicity. A total of 12 patients had grade 3 nonhematologic toxicities: nausea and vomiting (4 patients), reversible neurotoxicity (5 patients), and diarrhea (3 patients). No grade 4 toxicities were observed. Median time to progression was 12 (1–125) weeks. Survival in second line was 22 (4–326+) weeks. Overall disease control rate was 49% (complete remission = 3%; partial remission = 3%; stable disease > 12 weeks = 43%). Conclusions: This regimen is feasible and active with an acceptable toxicity profile; it can be safely administered in an outpatient setting. There is an urgent need for further investigation in phase III trials.
