Oxaliplatin often induces
peripheral neuropathy, a dose-limiting adverse reaction, and in rare cases leads to
sinusoidal obstruction syndrome. We thus conducted a retrospective cohort study to examine the relationship between
oxaliplatin-induced
peripheral neuropathy (OIPN) and hepatic impairment, and then perform a fundamental study to analyze the underlying mechanisms. Analysis of medical records in
cancer patients treated with
oxaliplatin indicated that laboratory test parameters of hepatic impairment including AST, ALT and APRI (AST to platelet ratio index) moderately increased during
oxaliplatin treatment, which was positively correlated with the severity of OIPN (grades 1-4), and associated with later incidence of survivors with OIPN grades ≥2. In mice, hepatic injury induced by CCl4 or
ethanol accelerated OIPN in mice, an effect prevented by inactivation of high mobility group box 1 (
HMGB1), known to participate in OIPN, by the
neutralizing antibody or
thrombomodulin alfa capable of promoting its
thrombin-dependent degradation.
Oxaliplatin also aggravated the hepatic injury in mice. CCl4 released
HMGB1 from cultured hepatic parenchymal cells, and
oxaliplatin at clinically achievable concentrations released
HMGB1 from hepatic parenchymal and non-parenchymal cells. Our clinical and preclinical data suggest that the development of mild hepatic impairment during
oxaliplatin treatment is associated with later aggravation of OIPN.
