Safety of intra-cerebrospinal fluid chemotherapy in onco-haematological patients: a retrospective analysis of 627 interventions
Abstract
Intra-cerebrospinal fluid chemotherapy (ICC) is used widely to treat or prevent neoplastic meningitis (NM), although its safety has not been thoroughly assessed. We aimed to analyse the incidence, severity and cause of the adverse reactions provoked by ICC in a cohort of onco-haematological patients. We retrospectively reviewed all the adverse reactions related to ICC procedures performed by the same researcher over a 5-year period. We classified them according to their severity and cause, and examined their association with certain characteristics of the patients and interventions. A total of 627 procedures were performed on 124 patients, in which 59 adverse reactions were documented (9.4 %). Thirty-two (54 %) of these were considered severe and 30 (51 %) were due to the drug itself. NM was associated with a higher incidence of adverse reactions (p = 0.002) and severe adverse reactions (p < 0.001). Adverse reactions were more common (p = 0.028) and more often severe (p = 0.008) when an Ommaya reservoir was used, as opposed to the lumbar puncture procedure. The use of liposomal cytarabine was also associated with a higher incidence of adverse reactions (p < 0.001) and serious adverse reactions (p < 0.001) than immediate-release...Continue Reading
