title: Oxaliplatin and Bolus-Modulated 5-Fluorouracil as a Second-Line Treatment for Advanced Pancreatic Cancer: Can Bolus Regimens Replace FOLFOX When Considered for Second Line?
abstract: Objective. Comparing activity of 2 regimens combining oxaliplatin to bolus modulated fluorouracil as second line treatment in advanced pancreatic adenocarcinoma pretreated with gemcitabine-containing schedule. Methods. Forty eight patients with advanced pancreatic adenocarcinoma were randomly assigned to receive either FU 500 mg/m(2) IV bolus weekly ×6 weeks plus leucovorin 500 mg/m(2) IV weekly for 6 weeks during each 8-week cycle plus oxaliplatin 85 mg/m(2) IV on weeks 1, 3, and 5 of each 8-week (FLOX) OR receive weekly intravenous infusions of oxaliplatin 40 mg/m(2), 5-FU 500 mg/m(2), and leucovorin 250 mg/m(2) (3 weeks on, 1 week off). Results. Non progression(PR+SD) was found in 33.5% for first regimen and 29% for second regimen, and 37.5% had clinical benefit (FLOX regimen) compared to 50% in 3-weeks regimen. The median TTP was 3.9,4 months respectively. Median OS was 8, 9 months for both regimens. Only one case in 3-weeks arm suffered from grade IV diarrhea. Two cases > grade 2 neutropenia were observed; one in each treatment groups. Grade 3 anemia was recorded in 3 patients (2 in FLOX arm, one in 3-weeks arm). Conclusions. Both regimens showed encouraging efficacy, acceptable toxicity, and clinical benefit.
