| アブストラクト | BACKGROUND: Gemcitabine is widely used in the treatment of various cancers. This study aims to evaluate gemcitabine-associated adverse events (AEs) using the Food and Drug Administration Adverse Event Reporting System (FAERS) database. RESEARCH DESIGN AND METHODS: We analyzed data spanning from January 2004 to June 2023. Employing reporting odds ratio (ROR) and Bayesian confidence propagation neural network (BCPNN) algorithms, we identified AEs with positive signals in patients administered gemcitabine. RESULTS: Out of 16,623,939 reports, 23,645 involved gemcitabine as the 'primary suspected (PS)' resulting in 74,306 AEs. Consistent with the reports in the specification and clinical trials, thrombocytopenia, pyrexia, neutropenia, and anemia were the most common AEs. Notably, our study identified some unexpected AEs such as abdominal pain, pleural effusion, ascites, and gastrointestinal hemorrhage, among others. The most significant SOC was 'Blood and lymphatic system disorders'. The median onset time for gemcitabine-related AEs was 24 days (interquartile range [IQR] 6-82 days), with most cases occurring within the initial 30 days following gemcitabine administration. CONCLUSION: Gemcitabine is associated with a broad spectrum of AEs affecting multiple organ systems, with a notable incidence of hospitalization. The study highlights both expected and unexpected AEs, which could enhance future clinical applications and safety of gemcitabine. |
