Abstract 3644

Background

Gemcitabine/nabpaclitaxel is a polychemotherapy regimen currently used to treat metastatic pancreatic cancer patients with a good performance status (PS). Gemcitabine/nabpaclitaxel significantly improves overall survival (OS) and progression free survival (PFS), but few data are available in elderly patients. Therefore, we carried out a retrospective analysis to evaluate efficacy and safety profile of this combination in a cohort of elderly patients.

Methods

All cases of metastatic pancreatic adenocarcinoma in patients over 70 years old treated at our Department between 2014 and 2016 with gemcitabine/nab-paclitaxel were retrospectively reviewed. The primary objective was to evaluate the safety and efficacy of this regimen in the elderly population.

Results

Forty-six patients with a median age of 73 years (range: 70-79) were included in this analysis: males: 19 (41%); PS2: 6 (13%); primary location: head 26 (57%); biliary stent:14 (30%); previous surgery: 5 (11%); adjuvant CT 5 (11%). Overall response rate (ORR) was 33.3%; median progression-free survival (PFS) was 7 mo (95% CI 5.89-9.10) and median overall survival (OS) was 12 mo (95% CI 10.7-16.13). Treatment was well tolerated. No grade 4 toxicity was reported. Grade 3 toxicity included neutropenia in 5 pts (10%), peripheral neuropathy in 2 pts (4.3%), thrombocytopenia in 2 pts (4%), diarrhea in 3 pts (6.5%), nausea and vomiting in 1 pt (2.1%), and fatigue in 2 pts (4.3%). No significant difference in terms of efficacy and safety was recorded with a cohort of 50 pts under 70 years of age: ORR: 36.6%; median PFS 6.7 mo (95% CI 5.966-8.034), and median OS 10.5 mo (95% CI 7.864-12.136). Finally, pain control was achieved in 15 of 24 patients (62.5%) with a performance status improvement of 10% according to the Karnofsky scale.

Conclusions

Although pancreatic cancer mostly affects elderly people, clinical trials often include few elderly pts. These data suggest that combination of gemcitabine plus nab-paclitaxel is effective and safe in an unselected population of elderly pts showing no differences in outcome between older patients and younger patients treated with this combination.
