Pharmacovigilance of carmustine: distinct neurotoxic and systemic safety signals identified in FAERS.
Article in BMC cancer, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundCarmustine (BCNU), a nitrosourea alkylating agent, is used in malignant gliomas, lymphomas, and hematopoietic stem cell transplantation. Although its major toxicities are recognized, comprehensive postmarketing evidence on the broader spectrum of carmustine related adverse event signals remains limited. This study evaluated carmustine related reporting signals using real world pharmacovigilance data.
methodsAdverse drug reaction (ADR) reports identifying BCNU as the primary suspect were extracted from the FDA Adverse Event Reporting System (FAERS, Q1 2004-Q1 2024). Disproportionality analyses using reporting odds ratio (ROR), proportional reporting ratio (PRR), information component (IC), and empirical Bayesian geometric mean (EBGM) were performed at both system organ class (SOC) and preferred term (PT) levels, with stratification by sex.
resultsIn total, 718 BCNU reports with 3,091 preferred terms were analyzed. Significant signals emerged for nervous system disorders (ROR = 2.74), blood and lymphatic system disorders (ROR = 2.95), and infections (ROR = 2.15). At the PT level, eosinophilic meningitis, pneumocephalus, and intracranial hypotension showed strong disproportional reporting signals among carmustine related reports. Descriptive sex stratified reporting patterns were observed, including intracranial hypotension in female reports and pseudomeningocele in male reports.
conclusionCarmustine related FAERS reports showed distinct neurotoxic, hematologic, and procedural reporting patterns, some with descriptive sex specific differences. These findings emphasize the need for continued post-marketing surveillance to inform clinical practice and optimize risk mitigation.
