| アブストラクト | BACKGROUND: Intravesical chemotherapy and immunotherapy are common adjuvant treatments for non-muscle invasive bladder cancer post-surgery. Analyzing adverse events linked to these therapies, can assist in clinical decision-making and risk assessment. STUDY DESIGN AND METHODS: Disproportionality analysis was conducted to analyze data from the Food and Drug Administration Adverse Event Reporting System database from the first quarter of 2004 to the first quarter of 2024, exploring potential positive signals between Bacillus Calmette-Guerin, mitomycin-C, epirubicin, gemcitabine, and adverse events. RESULTS: The database retrieved 2018, 140, 31, and 85 adverse event reports associated with Bacillus Calmette-Guerin, mitomycin-C, epirubicin, and gemcitabine, respectively. Adverse reactions not mentioned in the label, such as aortic aneurysm and ocular congestion, were observed in preferred term level related to Bacillus Calmette-Guerin. Mitomycin-C exhibited specificity in skin and subcutaneous tissue diseases not reflected in the package insert. Gemcitabine-induced adverse drug reactions showed signals in vascular and lymphatic diseases meeting the screening criteria of all 4 indicators, with capillary leakage syndrome being the preferred term with the highest signal intensity. CONCLUSION: This study observed new adverse event signals, providing important assistance for drug selection in adjuvant therapy for non-muscle invasive bladder cancer postoperatively. |
