FOLFOX-4 regimen as fist-line chemotherapy in elderly patients with advanced gastric cancer: a safety study

Abstract

Gastric cancer is often diagnosed in advanced stage (AGC) and in elderly patients. Current chemotherapies induce severe toxicity and are difficult to deliver. Some authors have shown the activity and safety of oxaliplatin with various 5-fluorouracil (FU) and leucovorin (LV) infusions in AGC. The aim of our study was to evaluate the feasibility of the FOLFOX-4 regimen in elderly patients with AGC. From 6/2003 to 7/2005, 33 patients (median age 74 years, range 66-79 years) were enrolled into the study. 31 patients were assessable for the safety analysis and for response. We recorded complete response in 4 patients (13%), partial response in 6 patients (19%), 9 (29%) stable disease and 12 progressive disease for an overall response rate of 32% (95% CI, 16% to 48%). At median follow-up of 20 months the median time to progression was 6.4 months. The therapy was well tolerated, the main G1/2 toxicities were nausea, vomiting and diarrhea. Only 2 patients suffered from severe vomiting. Severe hematologic toxicities were uncommon. Anemia G3 was recorded in 3 patients, neutropenia G3 in 6 patients and febrile neutropenia in 1 patient. G1 and G2 neurotoxicity were a common event while G3 sensorial neuropathy was not reported. We conclude that although our patients were elderly and most had a PS 2, the regimen was manageable, easy to deliver, well accepted by the patients and active.
