Efficacy of S-1 monotherapy for older patients with unresectable pancreatic cancer: A retrospective cohort study

摘要

Objectives: Pancreatic cancer is a fatal malignancy that frequently occurs in older patients. However, limited evidence is available on the effects of chemotherapy on older patients with unresectable pancreatic cancer. Here we explored the efficacy of S-1, an oral fluorouracil drug, compared with gemcitabine, as first-line chemotherapy.
