Background: This study aimed to clarify whether or not switching lenograstim for pegfilgrastim enables the sustained effects of decreasing neutropenia and shortening the length of hospitalization in patients receiving taxane-based chemotherapy. Methods: Patients being treated docetaxel and nedaplatin therapy in our facility were enrolled in this study. In the first courses of therapy, we administered lenograstim when grade 3 neutropenia occurred (group A). In the second or subsequent courses of therapy, we administered lenograstim when grade 2 neutropenia occurred through March 2015 (group B) and then administered pegfilgrastim on day 2 of chemotherapy from April 2015 (group C). We retrospectively evaluated the incidence of severe neutropenia and febrile neutropenia (FN), length of hospitalization, and other adverse events. Results: FN was observed in 10% (4/41) of group B and 0% (0/36) of group C (p=0.0511). Grade 3-4 neutropenia occurred in 76% (31/41) of group B and 3% (1/36) of group C (p<0.0001). The median length of hospitalization was 12 days in group B and 6 days in group C (p<0.0001). Conclusion: Pegfilgrastim significantly reduced the incidence of neutropenia and the length of hospitalization. Pegfilgrastim may therefore improve the quality of life of these patients.
