Objectives: The aim of this study was to evaluate the efficacy and safety of the combination Gemcitabine (Gem) plus nab-Paclitaxel (NabP) (Gem/NabP), followed bymaintenance Gemin older adults with locally advanced or metastatic pancreatic cancer (PC). Materials and methods: In this prospective observational study, the induction chemotherapy consisted of NabP 125 mg/m(2) followed by Gem 1000 mg/m(2) on days 1, 8, and 15 of a 4-week cycle. After a maximum of 3 cycles, patients without evidence of progressive disease (PD) were administered Gem 1000 mg/m(2) weekly for 3 of 4 weeks as maintenance therapy until documentation of PD or unacceptable toxicity. The primary endpoint was six-month disease-control rate (DCR). Results: Overall, 36 patients >70 years withmetastatic or locally advanced PCwere enrolled at participating Institutions. After completion of Gem/NabP, 18 (50%) patients achieved partial response, 13 (36%) had stable disease, and 5 (14%) had PD. Thirty-one patients (86%) received Gem monotherapy as maintenance treatment for a median of 3 cycles (range, 2-9 cycles). Six-month DCR was 61% (95% CI, 45-77), median PFS was 6.4 months (95% CI, 5.4-8.3), and median OS was 13.4 months (95% CI, 11.1-16.7). During Gem/NabP regimen, the most common grade 3 toxicity included neutropenia (22%), anemia (19%) and thrombocytopenia (8%). Grade 3 neuropathy was not observed. During Gem maintenance therapy, grade 3 hematological toxicity was described in 6 patients (19%). Conclusion: Gem/NabP followed by maintenance Gem appears to be safe and effective for older patients with locally advanced or metastatic PC. (C) 2019 Published by Elsevier Ltd.
