Effect Of Folfirinox With Peg-G-Csf For Unresectable/Recurrent Pancreatic Cancer.

411Background: FOLFIRINOX (FFX) is a standard therapy for unresectable/recurrent pancreatic cancer, but it is associated with a high frequency of severe adverse events, especially blood toxicity. Human pegylated granulocyte colony-stimulating factor (PEG-G-CSF) can reduce the outpatient frequency during outpatient chemotherapy. However, there are few reports on the effectiveness of PEG-G-CSF in preventing febrile neutropenia during FFX. We retrospectively investigated the usefulness of PEG-G-CSF in reducing the incidence of FN during FFX. Methods: From June 2014 to January 2017, 40 patients with unresectable pancreatic cancer received FFX (including modified FFX) at our hospital. Twenty-three patients were administered PEG-G-CSF as primary/secondary preventive therapy (G group) and 17 were not administered any G-CSF (NG group). Results: The median patient ages in the G and NG groups were 65 (range, 48-78) and 63 (range, 42-81) years, respectively, and the male to female ratios were 13:10 and 11:6, respect...
