INTRODUCTION: Data suggest a role of the potassium channel SK3 (KCNN3 gene) in oxaliplatin-induced neurotoxicity (OIN). Length variations in the polymorphic CAG repeat of the KCNN3 gene may be associated with the risk of OIN. MATERIALS AND METHODS: We performed patch-clamp experiments on HEK293 cell lines, expressing SK3 channel isoforms with short (11) or long (24) CAG repetitions, to measure intracellular calcium concentrations to test the effects of oxaliplatin on current density...

Neurological complications of paediatric cancers are a substantial problem. Complications can be primary from central nervous system (CNS) spread or secondary from indirect or remote effects of cancer, as well as cancer treatments such as chemotherapy and radiation therapy. In this review, we present the clinical and imaging findings of rare but important neurological complications in paediatric patients with cancer. Neurological complications are classified into three phases: pre-treatment, treatment and post-remission...

Background: Histone deacetylases (HDACs) regulate gene expression by changing histone deacetylation status. Neurotoxicity is one of the major side effects of cisplatin, which reacts with deoxyribonucleic acid (DNA) and has excellent antitumor effects. Suberoylanilide hydroxamic acid (SAHA) is an HDAC inhibitor with neuroprotective effects against cisplatin-induced neurotoxicity. Purpose: We investigated how cisplatin with and without SAHA pretreatment affects HDAC expression/activity in the brain by using 6-([18 F]fluoroacetamido)-1-hexanoicanilide ([18 F]FAHA) as a positron emission tomography (PET) imaging agent for HDAC IIa...

Oxaliplatin-based chemotherapy is a well-established regimen for patients with inoperable and metastatic colorectal cancer. However, one of the major limitations of oxaliplatin-based chemotherapy is sensory neuropathy. It was previously reported that introduction of intermittent oxaliplatin treatment to an oxaliplatin-based regimen has a significant benefit on efficacy or safety. Here, we prospectively assessed whether efficacy and safety of first-line chemotherapy for advanced colorectal cancer are achieved by introduction of withdrawal of oxaliplatin treatment for a certain period (intermittent oxaliplatin treatment)...

The potential neurotoxic effects of anticancer drugs, like doxorubicin (DOX) and mitoxantrone (MTX; also used in multiple sclerosis), are presently important reasons for concern, following epidemiological data indicating that cancer survivors submitted to chemotherapy may suffer cognitive deficits. We evaluated the in vitro neurotoxicity of two commonly used chemotherapeutic drugs, DOX and MTX, and study their underlying mechanisms in the SH-SY5Y human neuronal cell model. Undifferentiated human SH-SY5Y cells were exposed to DOX or MTX (0...

Cytotoxic drugs applied in chemotherapy enter the aquatic environment after patient's metabolism and excretion, in both main compounds and their respective metabolites. The increased consumption and discharge of these drugs raise concern on the genotoxic burden to non-target aquatic species, due to their unselective action on DNA. Settlement and adsorption of cytotoxic drugs to aquatic sediments pose risks to benthic species through chronic exposure. The aim of the present study was to assess the effects induced by the anticancer drug cyclophosphamide (CP) on the polychaete Nereis diversicolor, after 14 days of exposure to environmental relevant concentrations (10, 100, 500 and 1000 ng L-1 )...

Peripheral Nervous System (PNS) neurotoxicity caused by cancer drugs hinders attainment of chemotherapy goals. Due to leakiness of the blood nerve barrier, circulating chemotherapeutic drugs reach PNS neurons and adversely affect their function. Chemotherapeutic drugs are designed to target dividing cancer cells and mechanisms underlying their toxicity in postmitotic neurons remain to be fully clarified. The objective of this work was to elucidate progression of events triggered by antimitotic drugs in postmitotic neurons...

Although the benefit for any type of antifungal prophylaxis in patients with acute myelogenous leukemia is well accepted, less is known about the risk for invasive fungal infections (IFIs) and the optimal prophylaxis strategies in patients with acute lymphocytic leukemia (ALL). Based on recent studies, ALL is a disease that appears to be associated with significant risk for IFIs. The pharmacokinetic interactions between azoles and vincristine, an antineoplastic agent that is part of modern combination chemotherapies in ALL, results in clinically significant neurotoxicity that makes the use of azoles problematic...

Liu Jun Zi Tang (LJZT) has been used to treat functional dyspepsia and depression, suggesting its effects on gastrointestinal and neurological functions. LJZT is currently used as a complementary therapy to attenuate cisplatin-induced side effects, such as dyspepsia. However, its effect on chemotherapy-induced neuropathic pain or neurotoxicity has rarely been studied. Thus, we explored potential mechanisms underlying LJZT protection against cisplatin-induced neurotoxicity. We observed that LJZT attenuated cisplatin-induced thermal hyperalgesia in mice and apoptosis in human neuroblastoma SH-SY5Y cells...

BACKGROUND: Glioblastoma (GBM) is the most common malignant brain tumor in adult patients. Tumor recurrence commonly occurs around the resection cavity, especially after subtotal resection (STR). Consequently, the extent of resection correlates with overall survival (OS), suggesting that depletion of postoperative tumor remnants will improve outcome. OBJECTIVE: To assess safety and efficacy of adding stereotactic radiosurgery (SRS) to the standard treatment of GBM in patients with postoperative residual tumor...

BACKGROUND: Chemotherapy-induced peripheral neuropathy (CIPN) is a significant side effect of cancer treatment, potentially leading to early cessation of chemotherapy, enduring symptoms and long-lasting disability. Evidence from preclinical and clinical studies suggests that duloxetine, a serotonin-noradrenaline reuptake inhibitor, may be effective in the symptomatic treatment of CIPN. This double blind, placebo controlled, phase II randomised cross-over trial aims to determine whether treatment with duloxetine results in a reduction in chronic neuropathic symptoms experienced as a result of neurotoxic chemotherapy treatment...

Life-threatening chemotherapy-induced thrombocytopenia can increase the risk of bleeding due to a dramatic low platelet count, which may limit or delay treatment schedules in cancer patients. The pressing need for the rapid alleviation of the symptoms of thrombocytopenia has prompted us to search for novel highly effective and safe thrombopoietic agents. Pharmacological investigations have indicated that dencichine can prevent and treat blood loss and increase the number of platelets. On the basis of the neurotoxicity of dencichine, D-dencichine is artificially synthesized in the laboratory...

INTRODUCTION: The prognosis for leptomeningeal metastasis (LM) remains extremely poor regardless of intrathecal chemotherapy with various drugs, and thus, new treatments are necessary. Butyrate is an endogenous 4-carbon saturated fatty acid, has been investigated as an anti-tumor agent because of its multiple suppressive effects on several tumors. In this study, we investigated the cellular basis of sodium butyrate (SB), a sodium salt compound of butyrate, in vitro and evaluated the clinical potential of intrathecal SB administration for LM in vivo...

Because the number of cytotoxic agents available for the treatment of metastatic colorectal cancer (mCRC) is limited, rechallenge with the same chemotherapy agents can provide a continuum of treatment. This study investigated the efficacy and feasibility of oxaliplatin rechallenge in mCRC patients who had been previously exposed to oxaliplatin-based chemotherapy. Patients were included if they had mCRC and evaluable disease, had remained disease-free or progression-free for at least 6 months after the last dose of prior oxaliplatin-based therapy, and were retreated with oxaliplatin therapy...
