abstract = {BACKGROUNDPaclitaxel chemotherapy frequently induces
dose-limiting sensory axonal polyneuropathy. Given that
sensory symptoms are challenging to assess objectively in
clinical practice, an easily accessible biomarker for
chemotherapy-induced polyneuropathy (CIPN) holds the
potential to improve early diagnosis. Here, we describe
neurofilament light chain (NFL), a marker for neuroaxonal
damage, as a translational surrogate marker for
CIPN.METHODSNFL concentrations were measured in an in vitro
model of CIPN, exposing induced pluripotent stem
cell-derived sensory neurons (iPSC-DSNs) to paclitaxel.
Patients with breast or ovarian cancer undergoing paclitaxel
chemotherapy, breast cancer control patients without
chemotherapy, and healthy controls were recruited in a
cohort study and examined before chemotherapy (V1) and after
28 weeks (V2, after chemotherapy). CIPN was assessed by the
validated Total Neuropathy Score reduced (TNSr), which
combines patient-reported symptoms with data from clinical
examinations. Serum NFL (NFLs) concentrations were measured
at both visits with single-molecule array
technology.RESULTSNFL was released from iPSC-DSNs upon
paclitaxel incubation in a dose- and time-dependent manner
and was inversely correlated with iPSC-DSN viability. NFLs
strongly increased in paclitaxel-treated patients with CIPN,
but not in patients receiving chemotherapy without CIPN or
controls, resulting in an $86\%$ sensitivity and $87\%$
specificity. An NFLs increase of +36 pg/mL from baseline was
associated with a predicted CIPN probability of more than
0.5.CONCLUSIONNFLs was correlated with CIPN development and
severity, which may guide neurotoxic chemotherapy in the
future.TRIAL REGISTRATIONClinicalTrials.gov
