PURPOSE: The dose limiting toxicity of oxaliplatin (l-HOP) is neurotoxicity, which is characterized by an acute neuropathy and a clinically distinct chronic neuropathy. This randomized study evaluated if prolonged l-HOP infusion over the conventional l-HOP schedule was useful in reducing acute and possibly chronicl-HOP induced neurotoxicity in colon and gastric cancer patients receivingl-HOP-based regimen as adjuvant chemotherapy. METHODS:Sixty-four patients were randomly assigned to group A (26 colon and 6 gastric cancer) and to group B (23 colon and 9 gastric cancer). Chemotherapy in both groups consisted of l-HOP 85 mg/m(2) i.v. only on day 1, with leucovorin 100 mg/m(2) i.v. as a 2-h infusion followed by bolus 5-fluorouracil (5-FU) 400 mg/m(2)/day and a 22-h infusion of 5-FU 600 mg/m(2)/day, repeated for two consecutive days every 2 weeks for a maximum of 12 cycles. Patients in group A received l-HOP as a continuous 6-h i.v. infusion, and patients in group B received l-HOP as the conventional 2-h i.v. infusion. RESULTS: The percentage of patients presenting with grade >/=2 neurotoxicity was statistically lower in group A than in group B (28.1% vs. 59.3%: P = 0.02). There was a statistically lower percentage of cycles with grade >/=2 neurotoxicity in group A (6.1%) than in group B (18.5%) (P < 0.001). CONCLUSIONS: This study suggests that l-HOP as a continuous 6-h infusion is useful in preventing and reducing acute l-HOP induced neurotoxicity in patients with colon and gastric cancer receiving FOLFOX-4 regimen as adjuvant treatment.
