Real-World Analysis Reveals Unexpected Safety Signals for Temozolomide in Glioma Treatment
- A comprehensive analysis of 13,608 temozolomide-related adverse events from the FDA's FAERS database identified both expected hematologic toxicities and unexpected safety signals including pulmonary embolism and opportunistic infections.
- The study found that blood and lymphatic system disorders showed the strongest safety signal with a relative odds ratio of 5.94, confirming temozolomide's known myelosuppressive effects in real-world settings.
- Unexpected adverse events such as pulmonary embolism (ROR 4.96) and Pneumocystis jirovecii pneumonia (ROR 7.09) emerged as significant safety concerns, suggesting the need for updated clinical monitoring guidelines.
- The findings support lowering thresholds for thromboprophylaxis and Pneumocystis prophylaxis in temozolomide-treated patients compared to current clinical guidelines.
