The association of benzodiazepine and benzodiazepine-related drugs with outcomes after surgery for colorectal cancer

Résumé

Benzodiazepines increase plasma brain-derived neurotrophic factor (BDNF) level which, in turn, may improve survival in colorectal cancer (CRC) patients. This study aimed to evaluate the associations between benzodiazepine and benzodiazepine-related drugs (BZRD) use and outcomes of patients operated for CRC. This is a retrospective cohort study including patients operated for CRC at Limoges' University Hospital between 2010 and 2019. Data were collected from two sources: medical records of patients in the digestive, general and endocrine surgery department at Limoges University Hospital and from the Haute-Vienne general cancer registry. Patients were divided into benzodiazepine users and non-users. Outcomes were overall survival (OS) and recurrence-free survival (RFS). Among 504 patients who underwent surgery for CRC, 125 (24.8%) patients were treated with benzodiazepine/BZRD drugs. Users and non-users of benzodiazepine/BZRD showed no statistically significant differences in 5-year OS (45.5 ± 1.9% vs. 46.5 ± 1.1% p = 0.25) and 5-year RFS (41.0 ± 2.1% vs. 39.6 ± 1.3%, p = 0.94), even after adjustment for confounders and propensity score (OS: aHR=1.02, 95%CI: 0.71-1.48; RFS: aHR=1.00, 95%CI: 0.72-1.40). Subgroup analysis on CRC patients with psychiatric disorders revealed that benzodiazepine users had better RFS (aHR=0.58, 95%CI: 0.35-0.96) compared with non-users, particularly, patients with stages III or IV of CRC had better OS (aHR=0.27; 95%CI: 0.12-0.59) and RFS (aHR=0.30, 95%CI: 0.15-0.62). OS and RFS was significantly better in patients taking benzodiazepines classified as anxiolytics, having longer half-life, and producing active metabolites. In conclusion, benzodiazepine use was not associated with outcomes in CRC patients. Nevertheless, in subgroup of patients with psychiatric disorders and advanced CRC stage, benzodiazepine could improve survival.
