Background: Pancreas adenocarcinoma is the sixth cause of cancer-related death worldwide and the mortality is increasing in the Western Countries. Recently, the association between nab-paclitaxel (nab-P) and gemcitabine (GEM) has significantly improved progression-free (PFS) and overall survival (OS) compared to GEM monotherapy (PFS: 5.5 vs 3.7 months; OS: 8.5 vs 6.7 months). Methods: Patients affected by metastatic pancreas adenocarcinoma were treated at the Department of Abdominal Oncology of the National Cancer Institute of Naples from July 2015 to July 2016 with nab-P at 125 mg per square meter of body-surface area followed by GEM at 1000 mg per square meter on days 1, 8, and 15 every 4 weeks. Computed tomography (CT) was done every three months of therapy. Toxicity was graded with NCI-CTC criteria v4.0. Objective responses were evaluated with RECIST. Analysis of time-to-progression is only descriptive. Pain was evaluated with a visual analogic scale. Results: Twenty-three patients were treated. Median age was 67 years (range: 45-81); 8 patients were ≥ 70 years old. Performance Status (PS) ECOG was 2 in 8 patients, 1 in 10 and 0 in 5. Twelve patients presented with diffuse hepatic metastases, 4 with carcinosis, 7 with more than one organ involvement. They received a median number of 13 administrations (range: 3-32) of therapy. During therapy Nab-P was reduced at 100 mg per square meter in all patients. The most common G3/G4 adverse events were neutropenia (13.0% G4, 8.6% G3, none was febrile), neuropathy (30.4% G3) and asthenia (G3 17.3%). The disease control rate was 43.4% (PR+SD 10/23); PR was registered in three patients (response rate: 13.0%). Twelve patients progressed and seven dead at September 20. The median time-to-progression was 7.9 months (95% confidence interval 5.8-11.2). After three months of therapy the PS improved in 14 patients as well as pain in 18 patients. Conclusions: We present an experience with nab-P and GEM association in a series with poor PS and highly metastatic disease relatively to the previous randomized study. The schedule is feasible with nab-P at 100 mg per square meter and it achieves a good disease control rate as well as a clinical benefit.
