Background: Despite a large number of randomized trials, there is no consensus as to the best regimen for advanced gastroesophageal cancer. Combination therapy with docetaxel, cisplatin, and 5-FU has shown increased response rates, progression-free survival (PFS) and overall survival (OS), but at the cost of significant toxicity. Based on a small phase II study, FLOT has been adopted by some groups given its better toxicity profile. We aim at reporting our experience with this regimen Methods: Patients with unresectable advanced gastroesophageal adenocarcinoma who received FLOT (oxaliplatin 85 mg/m2, leucovorin 200 mg/m2, and fluorouracil 2600 mg/m2 as a 24h infusion in combination with docetaxel 50 mg/m2 on day 1 every 2 weeks) as first-line therapy at our institution were retrospectively evaluated. PFS and OS were estimated by the Kaplan-Meier method. Results: A total of 23 patients were reviewed, most of them with metastatic disease (60%). Median age was 56 years (range 26–76) and 74% were male. Median PFS and OS were 5,2 (95% CI 4,0-6,3) and 8,5 months (95% CI 4,4-12,6), respectively. Only 13%of the patients experienced prolonged PFS (>12 months). There were no deaths due to the treatment. Conclusions: Before FLOT could be adopted as a first-line regimen for metastatic gastroesophageal cancer, phase III trials are urgently needed comparing FLOT with more traditional regimens.
