Abstract

The present study aimed to evaluate whether the cerebrospinal fluid (CSF) neurofilament light chain (NfL) is a potential prognostic marker for patients with leptomeningeal metastasis (LM). NfL levels were measured in CSF using a single‑molecule array assay. A total of 42 patients with LM who were treated with ventriculo‑lumbar perfusion (VLP) chemotherapy and had available stored CSF samples from the lumbar subarachnoid space before VLP chemotherapy were included in the present study, in order to investigate the prognostic value of CSF NfL. The median CSF NfL level in patients with LM was 8.15 ng/ml; 30% of patients who had died at the time of analysis had CSF NfL levels higher than the calculated overall prognostic cut‑off value (11 ng/ml). The median overall survival after initiation of VLP chemotherapy was significantly longer in patients with LM and low CSF NfL levels compared with in patients with LM and high CSF NfL levels (P<0.001). The statistical significance remained after adjusting for other known prognostic factors and in a subgroup analysis according to age. In conclusion, CSF NfL could be considered a putative prognostic marker in patients with LM treated with VLP chemotherapy.
