Treatment patterns, toxicity, and outcomes of elderly patients with advanced pancreatic cancer receiving first-line chemotherapy.

71Background: Advanced pancreatic cancer (APC) has a poor prognosis despite treatment with palliative chemotherapy. Randomized trials have demonstrated improved overall survival (OS) with combination chemotherapy including 5-fluorouracil, irinotecan, leucovorin, and oxaliplatin (FOLFIRINOX) or nab-plaxictaxel and Gemcitabine (NG) compared to Gemcitabine (GEM) alone, however, combination therapy is associated with higher rates of toxicity. There is limited data regarding the efficacy and toxicity of FOLFIRINOX, NG, and GEM in elderly patients with APC. Objective: Describe the treatment patterns, toxicity, and outcomes of patients ≥ 65 years of age treated with first-line palliative FOLFIRINOX, NG, or GEM. Methods: Patients ≥ 65 diagnosed with APC from 2012-2016 and treated with palliative chemotherapy in Manitoba were identified from the Manitoba Cancer Registry. Retrospective review identified patients who received first line FOLFIRINOX, NG, or GEM. Patient and treatment characteristics including hematolo...
