First-line gemcitabine plus nab-paclitaxel for elderly patients with metastatic pancreatic cancer: Crossing the frontier of age?

Abstract Background Gemcitabine plus nab-paclitaxel (Gem-Nab) represents a standard first-line treatment for metastatic pancreatic cancer (mPC), but few data are available for elderly patients. We aimed to add evidence about safety and efficacy of Gem-Nab in this population. Methods We collected data of 156 patients with mPC aged ≥65 years receiving Gem-Nab. Patients were stratified according to age: Results The median age was 71 years (range: 65–87 years). The toxicity profile was similar between group 1 and 2, except for all-grade anaemia (92.1% vs. 78.7%, respectively; p = 0.04) and neurotoxicity (61.9% vs. 40.4%, respectively; p = 0.02), also as a result of a lower dose intensity of nab-paclitaxel (83.3% vs. 90.5%, respectively; p = 0.04) administered to oldest patients. The response rate was 25.6% (group 1 vs. 2: 20.0% vs. 29.7%; p = 0.12). After a median follow-up of 26.5 months, median overall survival (OS) and progression-free survival (PFS) were similar between the groups (p > 0.05). The starting dose of Gem-Nab did not affect PFS and OS (p > 0.05). Conclusion Gem-Nab is active and effective in older patients with mPC, with the results in line with the general mPC population enrolled in clinical trials. Mild dose modifications for elderly patients might be considered to improve safety without impairing efficacy.
