BACKGROUND Preoperative chemoradiotherapy has become the current standard regimen for locally advanced rectal cancer (LARC). However, the additional benefit of oxaliplatin to preoperative chemotherapy was still controversial. On one hand, oxaliplatin may improve the tumor response rate of even prolong the survival time. On the other hand, it can bring a series of adverse effects. Opinions vary ...

BACKGROUND Oxaliplatin, a platinum-based chemotherapeutic agent, causes an unusual acute peripheral neuropathy. Oxaliplatin-induced acute peripheral neuropathy appears in almost all patients rapidly after infusion, and is triggered or exacerbated by cold, while its mechanisms are poorly understood. In this study, the involvement of thermosensitive transient receptor potential channels (TRPA1, T...

To date, clinical studies combining the new generation of targeted therapies and chemotherapy have had mixed results. Preclinical studies can be used to identify potential antagonism/synergy between certain agents, with the potential to predict the most efficacious combinations for further investigation in the clinical setting. In this study, we investigated the sequence-dependent interactions ...

BACKGROUND Oxaliplatin chemotherapy induced neuropathy is a dose related cumulative toxicity that manifests as tingling, numbness, and chronic pain, compromising the quality of life and leading to discontinued chemotherapy. Patients report marked hypersensitivity to cold stimuli at early stages of treatment, when sensory testing reveals cold and heat hyperalgesia. This study examined the morpho...

Oxaliplatin, an anti-cancer chemotherapeutic agent used for the treatment of colorectal cancer, commonly causes gastrointestinal side-effects such as constipation, diarrhoea, nausea, and vomiting. Damage to enteric neurons may underlie some of these gastrointestinal side-effects, as the enteric nervous system (ENS) controls functions of the bowel. In this study, neuronal loss and changes to the...

Hepatic injury induced by oxaliplatin has been reported. Even though agents are available that reduce oxaliplatin-induced hepatocyte toxicity, their mode of action has remained obscure. In the present study, hepatic L02 cells were incubated with different combinations of oxaliplatin and carbocisteine. Significantly increased levels of reactive oxygen species (ROS) were found in L02 cells treate...

PURPOSE Most colon cancers show low sensitivity to treatment with oxaliplatin and a specific strategy is needed to overcome this problem. Our approach uses RNA interference to silence the expression of target genes responsible for the development of oxaliplatin resistance. Profile analysis of genes related to the regulation of apoptosis allowed identification of target genes showing the greates...

BACKGROUND Oxaliplatin displays potent activity in advanced colorectal cancer. The aim of this study was to estimate the potential efficacy of oxaliplatin for hepatic arterial infusion (HAI) chemotherapy. MATERIALS AND METHODS The anti-proliferative effects of oxaliplatin in human HT29 and NMG64/84 colon and COLO-357 MIA PaCa-2 and PMH2/89 pancreatic cancer cell lines and in fresh liver metas...

The influence of Glucagon-like peptide-1 (GLP-1) and Exendin-4 on development of intrahepatic cholangiocarcinoma (ICC) is evaluated in the study. In vitro tests, including acute toxicity test, cell colony formation assays, cells proliferation and apoptosis, transwell assay, were performed. An ICC in situ tumor animal model was established. Then, animals were randomly divided into four groups (n...

BACKGROUND Oxaliplatin is a platinum-based chemotherapy drug characterized by the development of acute and chronic peripheral neuropathies. The chronic neuropathy is a dose-limiting toxicity. We previously reported that repeated administration of oxaliplatin induced cold hyperalgesia in the early phase and mechanical allodynia in the late phase in rats. In the present study, we investigated the...
