Abstrakt: Purpose: To evaluate the health-related quality of life (HRQoL), global health status (GHS), and deterioration-free survival of an elderly population (> 70 years) with unresectable locally advanced (LAPC) or metastatic pancreatic cancer (mPC) treated with nab-paclitaxel in combination with gemcitabine. Methods: In this open-label, single-arm, multicenter, phase II trial, patients received 4-week cycles of intravenous (i.v.) nab-paclitaxel at a dose of 125 mg/m2, followed by i.v. injections of gemcitabine at a dose of 1000 mg/m2 on days 1, 8 and 15 until disease progression or unacceptable toxicity was observed. The primary outcome was the HRQoL (deterioration-free rate at 3 months as evaluated with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30. Results: Eighty patients (median age: 74.6 years) were enrolled (56 with mPC, 24 with LAPC). The percentage of patients who had not experienced deterioration at 3 months was 54.3% (95% CI 41.6–67.0%). The median (interquartile range) time until definite deterioration was 1.6 (1.1–3.7) months. The objective response rate and clinical benefit rate were achieved by 11 (13.8%, 95% CI 6.2–21.3%) and 54 patients (67.5%, 95% CI 57.2–77.8%), respectively. The median overall survival was 9.2 months (95% CI 6.9–11.5), and the median progression-free survival was 7.2 months (95% CI 5.8–8.5). Only fatigue and neutropenia demonstrated a grade 3–4 toxicity incidence > 20%. Conclusions: Our study confirms the clinical benefit of the combination of nab-paclitaxel and gemcitabine in an elderly population with pancreatic cancer in terms of improved survival and clinical response. However, we were unable to confirm a benefit in terms of quality-of-life. [ABSTRACT FROM AUTHOR]
