Abstract
ABSTRACT We have previously shown that intradermal injection of high-molecular-weight hyaluronan (500-1200 kDa) produces localized antihyperalgesia in preclinical models of inflammatory and neuropathic pain. In the present experiments, we studied the therapeutic effect of topical hyaluronan, when combined with each of 3 transdermal drug delivery enhancers (dimethyl sulfoxide [DMSO], protamine or terpene), in preclinical models of inflammatory and neuropathic pain. Topical application of 500 to 1200 kDa hyaluronan (the molecular weight range used in our previous studies employing intradermal administration), dissolved in 75% DMSO in saline, markedly reduced prostaglandin E 2 (PGE 2 ) hyperalgesia, in male and female rats. Although topical 500- to 1200-kDa hyaluronan in DMSO vehicle dose dependently, also markedly, attenuated oxaliplatin chemotherapy-and paclitaxel chemotherapy-induced painful peripheral neuropathy (CIPN) in male rats, it lacked efficacy in female rats. However, following ovariectomy or intrathecal administration of an oligodeoxynucleotide antisense to G-protein-coupled estrogen receptor (GPR30) mRNA, CIPN in female rats was now attenuated by topical hyaluronan. Although topical coadministration of 150 to 300, 300 to 500, or 1500 to 1750 kDa hyaluronan with DMSO also attenuated CIPN, a slightly lower-molecular-weight hyaluronan (70-120 kDa) did not. The topical administration of a combination of hyaluronan with 2 other transdermal drug delivery enhancers, protamine and terpene, also attenuated CIPN hyperalgesia, an effect that was more prolonged than with DMSO vehicle. Repeated administration of topical hyaluronan prolonged the duration of antihyperalgesia. Our results support the use of topical hyaluronan, combined with chemically diverse nontoxic skin penetration enhancers, to induce marked antihyperalgesia in preclinical models of inflammatory and neuropathic pain.

Abstract
ABSTRACT High-molecular-weight hyaluronan (HMWH) is an agonist at cluster of differentiation (CD)44, the cognate hyaluronan receptor, on nociceptors, where it acts to induce antihyperalgesia in preclinical models of inflammatory and neuropathic pain. In the present experiments, we studied the CD44 second messengers that mediate HMWH-induced attenuation of pain associated with oxaliplatin and paclitaxel chemotherapy-induced peripheral neuropathy (CIPN). While HMWH attenuated CIPN only in male rats, after ovariectomy or intrathecal administration of an oligodeoxynucleotide (ODN) antisense to G protein-coupled estrogen receptor (GPR30) mRNA, female rats were also sensitive to HMWH. Intrathecal administration of an ODN antisense to CD44 mRNA markedly attenuated HMWH-induced antihyperalgesia in male rats with CIPN induced by oxaliplatin or paclitaxel. Intradermal administration of inhibitors of CD44 second messengers, RhoA (member of the Rho family of GTPases), phospholipase C, and phosphatidylinositol (PI) 3-kinase gamma (PI3Kγ), attenuated HMWH-induced antihyperalgesia as does intrathecal administration of an ODN antisense to PI3Kγ. Our results demonstrated that HMWH induced antihyperalgesia in CIPN, mediated by its action at CD44 and downstream signaling by RhoA, phospholipase C, and PI3Kγ.

Abstract
Objective This narrative review describes experimental animal models of sensorineural hearing loss (SNHL) caused by ototoxic agents. Background SNHL primarily results from damage to the sensory organ within the inner ear or the vestibulocochlear nerve (cranial nerve VIII). The main etiology of SNHL includes genetic diseases, presbycusis, ototoxic agents, infection, and noise exposure. Animal models with functional and anatomic damage to the sensory organ within the inner ear or the vestibulocochlear nerve mimicking the damage seen in humans are employed to explore the mechanism and potential treatment of SNHL. These animal models of SNHL are commonly established using ototoxic agents. Methods A literature search of PubMed, Embase, and Web of Science was performed for research articles on hearing loss and ototoxic agents in animal models of hearing loss. Conclusions Common ototoxic medications such as aminoglycoside antibiotics (AABs) and platinum antitumor drugs are extensively used to induce SNHL in experimental animals. The effect of ototoxic agents in vivo is influenced by the chemical mechanisms of the ototoxic agents, the species of animal, routes of administration of the ototoxic agents, and the dosage of ototoxic agents. Animal models of drug-induced SNHL contribute to understanding the hearing mechanism and reveal the function of different parts of the auditory system in humans.

[PMID: 33232830 DOI: 10.1016/j.jpain.2020.11.004] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/07/2020] [Revised: 11/09/2020] [Accepted: 11/13/2020] [Indexed: 12/15/2022]
Abstract
TACAN (Tmem120A), a mechanotransducing ion channel highly expressed in a subset of nociceptors, has recently been shown to contribute to detection of noxious mechanical stimulation. In the present study we evaluated its role in sensitization to mechanical stimuli associated with preclinical models of inflammatory and chemotherapy-induced neuropathic pain (CIPN). Intrathecal administration of an oligodeoxynucleotide antisense (AS-ODN) to TACAN mRNA attenuated TACAN protein expression in rat dorsal root ganglia (DRG). While TACAN AS-ODN produced only a modest increase in mechanical nociceptive threshold, it markedly reduced mechanical hyperalgesia produced by intradermal administration of prostaglandin E2, tumor necrosis factor alpha, and low molecular weight hyaluronan, and systemic administration of lipopolysaccharide, compatible with a prominent role of TACAN in mechanical hyperalgesia produced by inflammation. In contrast, TACAN AS-ODN had no effect on mechanical hyperalgesia associated with CIPN produced by oxaliplatin or paclitaxel. Our results provide evidence that TACAN plays a role in mechanical hyperalgesia induced by pronociceptive inflammatory mediators, but not CIPN, compatible with multiple mechanisms mediating mechanical nociception, and sensitization to mechanical stimuli in preclinical models of inflammatory versus CIPN. PERSPECTIVE: We evaluated the role of TACAN, a mechanotransducing ion channel in nociceptors, in preclinical models of inflammatory and CIPN. Attenuation of TACAN expression reduced hyperalgesia produced by inflammatory mediators but had not chemotherapeutic agents. Our findings support the presence of multiple mechanotransducers in nociceptors.

Neuroprotective influence of sitagliptin against cisplatin-induced neurotoxicity, biochemical and behavioral alterations in Wistar rats. Mol Cell Biochem 2018; 455:91-97.

Abstract
Cisplatin has been extensively used as a chemotherapeutic agent since around 40 years, though its usage is limited due to severe adverse effects like neurotoxicity that might be because of oxidative stress. Hence, the present study was planned to investigate the possible protective role of sitagliptin against cisplatin-associated neurotoxic, biochemical, and behavioral alterations in male Wistar rats. Sitagliptin is a dipeptidyl peptidase-4 inhibitor that shows dual effects by improving the control on metabolism as well as decreasing the debility in cognitive function that is associated with increased insulin sensitivity and antioxidant property. For the in vitro assay, cultured rat pheochromocytoma (PC12) cells were exposed to different concentrations (10, 20, and 50 mM) of sitagliptin for 24 h. Cisplatin at 5 mM concentrations was added and cell viability was assessed using MTT assay. For in vivo study, animals were divided into four groups. Group I (Vehicle control): animals were administered 0.9% (w/v) of normal saline (1 mL/100 g; p.o.). Group II (Cisplatin): animals were treated with cisplatin (2 mg/kg; i.p.). Group III (Cisplatin + sitagliptin): animals were administered cisplatin along with sitagliptin. Group IV (Sitagliptin): animals were given sitagliptin (10 mg/kg; p.o.). All the treatments were administered for 8 weeks. On last day of treatment, behavioral evaluations including locomotor and rotarod studies were performed. In addition, several antioxidant enzymes were also estimated from cerebellum tissues; such as levels of thiobarbituric acid reactive substance (TBARS) were determined as a marker of lipid peroxidation, reduced glutathione (GSH) and catalase (CAT) were also estimated. Histological study of cerebellum tissue was also performed after performing the behavioral study. Exposure to cisplatin decreased cell viability in PC12 cells which were significantly increased by co-treatment with sitagliptin. In in vivo study, cisplatin significantly elevated the level of TBARS and reduced the level of antioxidant enzymes such as GSH and CAT which were significantly restored in sitagliptin + cisplatin group of rats. In addition, cisplatin impaired performance on the locomotor and rotarod activities, whereas sitagliptin significantly improved the performance of both activities. These results suggested the neuroprotective influence of sitagliptin by protecting cerebellum part of brain against cisplatin-induced toxicity.

Abstract
The mechanisms involved, and possible treatment targets, in orofacial pain due to cancer are poorly understood. The aim of the first of this two-part series is to review the involved pathophysiological mechanisms and explore their possible roles in the orofacial region. However, there is a lack of relevant research in the trigeminal region, and we have therefore applied data accumulated from experiments on cancer pain mechanisms in rodent spinal models. In the second part, we review the clinical presentation of cancer-associated orofacial pain at various stages: initial diagnosis, during therapy (chemo-, radiotherapy, surgery), and in the post-therapy period. In the present article, we provide a brief outline of trigeminal functional neuro-anatomy and pain-modulatory pathways. Tissue destruction by invasive tumors (or metastases) induces inflammation and nerve damage, with attendant acute pain. In some cases, chronic pain, involving inflammatory and neuropathic mechanisms, may ensue. Distant, painful effects of tumors include paraneoplastic neuropathic syndromes and effects secondary to the release of factors by the tumor (growth factors, cytokines, and enzymes). Additionally, pain is frequent in cancer management protocols (surgery, chemotherapy, and radiotherapy). Understanding the mechanisms involved in cancer-related orofacial pain will enhance patient management.

Abstract
Background Bogijetong decoction (BGJTD) is a herbal drug formulation used in the traditional Asian medicine to treat neuropathic insults associated with diabetes and anticancer therapy. To understand the biological basis of BGJTD on protective effects against neuropathy, we investigated physiological and biochemical responses of the sciatic nerves deranged by taxol injection or crush injury in the rats. Methods Dissociated Schwann cells and neurons were prepared from the sciatic nerve and dorsal root ganglia (DRG) respectively and were treated with taxol and BGJTD. The sciatic nerve in the rat was injected with taxol or given crush injury. Animals were then administered orally with BGJTD. Effects of BGJTD treatment on cultured cells and in vivo sciatic nerves and DRG tissues were examined by immunofluorescence staining and western blot analysis. Sciatic nerve regeneration was assessed by histological observation using retrograde tracing technique and by behavioral hot plate test. Eighteen different herbal components of BGJTD were divided into 4 subgroups and were used to select herbal drugs that enhanced neurite outgrowth in cultured neurons. Results Morphological abnormalities in the sciatic nerve axons and DRG tissue caused by taxol injection were largely improved by BGJTD treatment. BGJTD treatment enhanced neurite outgrowth in cultured DRG neurons and improved Schwann cell survival. Phospho-Erk1/2 levels were elevated by BGJTD administration in the injured- or taxol-injected sciatic nerves. Vimentin phosphorylation catalyzed by cell division cycle 2 (Cdc2) kinase was induced from Schwann cells in the sciatic nerves after taxol injection and crush injury, and phospho-vimentin levels were further upregulated by BGJTD treatment. Retrograde tracing of DiI-labeled DRG sensory neurons revealed growth-promoting activity of BGJTD on axonal regeneration. A drug group (Be) composed of 4 active herbal components which were selected by neurite growth-enhancing activity was as effective as BGJDT for the recovery of thermal sensitivity of the hind paws which had been suppressed by taxol administration. Conclusions These data suggest that BGJTD and its active herbal components may protects the peripheral nerve from damage caused by taxol injection and nerve crush.

Abstract
OBJECTIVES/HYPOTHESIS The aim of this study was to investigate the potential protective effect of curcumin on paclitaxel-induced ototoxicity in rats by means of immunohistochemical and histopathological analysis and distortion product otoacoustic emissions (DPOAEs). STUDY DESIGN Animal study. METHODS Forty Sprague-Dawley rats were randomized into five groups. Group 1 was administered no paclitaxel and curcumin during the study. Groups 2, 3, 4 and 5 were administered 5 mg/kg paclitaxel; 200 mg/kg curcumin; 5 mg/kg paclitaxel, followed by 200 mg/kg curcumin; 200 mg/kg curcumin and a day later 5 mg/kg paclitaxel followed intraperitoneally by 200 mg/kg curcumin once a week for 4 consecutive weeks, respectively. After the final DPOAEs test, the animals were sacrificed and their cochlea were prepared for hematoxylin and eosin and caspase-3 staining. RESULTS The DPOAEs thresholds and histopathological and immunohistochemical findings were substantially correlated in all groups. The histopathologic findings in the cochlea of the paclitaxel-treated animals showed not only changes in the organ of Corti, but also damage to the stria vascularis and spiral limbus, including nuclear degeneration, cytoplasmic vacuolization, and atrophy of intermediate cells. Additionally, cochlear changes in group 2, such as intense apoptosis, were confirmed by caspase-3 immunohistochemical staining. In group 4, coreceiving curcumin could not sufficiently prevent paclitaxel-induced ototoxicity, and the results in group 5 were similar to the control group. CONCLUSIONS In our study, we have concluded that pre- and coreceiving curcumin can significantly protect the cochlear morphology and functions on paclitaxel-induced ototoxicity in rats. Curcumin might be considered as a potential natural product that, used as a dietary supplement, could be easily given to patients undergoing paclitaxel chemotherapy. LEVEL OF EVIDENCE NA

Abstract
OBJECTIVES/HYPOTHESIS Cisplatin produces toxic lesions to outer hair cells (OHCs) in the cochlear base but not in the apex. The objective of this study was to compare the pharmacokinetic profile of cisplatin in scala tympani (ST) perilymph in the cochlear base and apex, respectively. STUDY DESIGN In vivo animal study. METHODS Forty-seven guinea pigs were given an intravenous bolus injection of an ototoxic dose of cisplatin. Ten to 240 minutes after cisplatin was given, blood, cerebrospinal fluid (CSF), and ST perilymph were aspirated within the same target time. ST perilymph was aspirated from the basal turn and from the apex of the cochlea by two different sampling techniques. Liquid chromatography with postcolumn derivatization was used for quantitative determination of the parent drug. RESULTS Ten minutes after administration, the concentration of cisplatin in ST perilymph was 4-fold higher in the basal turn of the cochlea than in the apex. At 30 minutes, the drug concentrations did not differ. At 60 minutes, the level of cisplatin in ST perilymph and blood UF was equivalent. The perilymph-blood ratio increased thereafter with time. CONCLUSION The pharmacokinetic findings of an early high concentration of cisplatin in the base of the cochlea and delayed elimination of cisplatin from ST perilymph compared to blood might correlate to the cisplatin-induced loss of OHCs in the base of the cochlea.

Abstract
Cisplatin, carboplatin, nedaplatin, and oxaliplatin are widely used in contemporary oncology; however, their ototoxic and neurotoxic side effects are quite different as discussed in this review. Cisplatin is considered the most ototoxic, but despite its reputation, the magnitude of hair cell loss that occurs with a single, large drug bolus is limited and confined to the base of the cochlea. For all of these platinum compounds, a major factor limiting damage is drug uptake from stria vascularis into the cochlear fluids. Disrupting the blood-labyrinth barrier with diuretics or noise exposure enhances drug uptake and significantly increases the amount of damage. Combined treatment with ethacrynic acid (a loop diuretic) and cisplatin results in rapid apoptotic hair cell death characterized by upregulation of initiator caspase-8 and membrane death receptor, TRADD, followed by downstream executioners, caspase-3 and caspase-6. Unlike cisplatin, nedaplatin and oxaliplatin are highly neurotoxic when applied to cochlear cultures preferentially damaging auditory nerve fibers at low concentrations and hair cells at high concentrations. Carboplatin, considered far less ototoxic than cisplatin, is paradoxically highly toxic to chinchilla inner hair cells and type I spiral ganglion neurons; however, at high doses it also damages outer hair cells. Hair cell death from cisplatin and carboplatin is characterized in its early stages by upregulation of p53; blocking p53 expression with pifithrin-α prevents hair cell death. Major differences in the toxicity of these four platinum compounds may arise from several different metal transporters that selectively regulate the influx, efflux, and sequestration of these drugs.

Abstract
Primary headache disorders are highly prevalent worldwide. The impact of primary headaches to the individual is significant and reflects physical suffering and decreased social and occupational functioning. The economic burden to society is enormous and represents direct healthcare costs and the indirect costs associated with decreased workplace productivity and work absences. The last decade has witnessed tremendous advances both in our understanding of the biology of headache and in our therapeutic armamentarium.

Effect of the chronic combined administration of cisplatin and paclitaxel in a rat model of peripheral neurotoxicity. Eur J Cancer 2008; 45:656-65. [PMID: 19091544 DOI: 10.1016/j.ejca.2008.10.038] [Citation(s) in RCA: 32] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2008] [Revised: 10/14/2008] [Accepted: 10/24/2008] [Indexed: 11/22/2022]
Abstract
We have characterised for the first time the general and neurological side effects experienced when using a series of chronic non-lethal cisplatin + paclitaxel schedules in Wistar rats, selected according to our previous experience and the animals' maximum tolerated dose. At the pathological level, the use of combination schedules was definitely more toxic at the kidney and sternal bone marrow level than the single-agent schedules. At the neurophysiological examination based on the assessment of the nerve conduction velocity measurement in the tail nerve, we identified only one combination schedule that was more neurotoxic than the similar schedules based on single-agent administration. This observation was confirmed by the neuropathological examination performed on the sciatic nerve, dorsal root ganglia, ventral and dorsal roots. Our study supports the hypothesis that the general and, to a lesser extent, neurological effects of a combination of cisplatin and paclitaxel are different from those of the administration of both drugs as single agents. We believe that these models may be useful for testing neuroprotective strategies.

Abstract
BACKGROUND Lamotrigine, an antiepileptic agent, has been reported as being effective in reducing symptoms of neuropathy associated with various etiologies. Based on such data, a multicenter double-blind, placebo-controlled, randomized trial was conducted to evaluate the effect of lamotrigine on pain and other neuropathic symptoms due to chemotherapy-induced peripheral neuropathy (CIPN). METHODS Patients with symptomatic CIPN with symptom scores of either 1) >3 on a 0-10 Numerical Rating Scale (NRS) or 2) >1 on the 0-3 the Eastern Cooperative Oncology Group (ECOG) neuropathy scale (ENS) were eligible (higher numbers corresponding to greater severity of symptoms in both scales). Patients were randomly assigned to receive lamotrigine (target dose of 300 mg/day) or placebo for 10 weeks. Endpoints were measured biweekly. RESULTS In all, 131 patients were enrolled. Both groups were well matched at baseline. Over the 10-week period of the trial, the average pain scores (NRS) for the lamotrigine and placebo arms declined in both arms, with no statistically significant difference noted between the changes in the 2 groups (0.3 and 0.5 unit reduction from baseline, respectively; P=.56). Similarly, decreases in the ENS with therapy were not statistically different (0.4 and 0.3, respectively; P=.3). Changes in other subjective symptom scales were also not found to be statistically different between the 2 groups. Toxicities were mild and similar in each group. CONCLUSIONS The results suggest that lamotrigine is not effective for relieving neuropathic symptoms in patients because of CIPN.

Abstract
Peripheral neuropathy is a well recognized toxicity of taxanes, usually resulting to dose modification and changes in the treatment plan. Taxanes produce a symmetric, axonal predominantly sensory distal neuropathy with less prominent motor involvement. A "dying back" process starting from distal nerve endings followed by effects on Schwann cells, neuronal body or axonal transport changes and a disturbed cytoplasmatic flow in the affected neurons is the most widely accepted mechanism of taxanes neurotoxicity. The incidence of taxanes-induced peripheral neuropathy is related to causal factors, such as single dose per course and cumulative dose and risk factors including treatment schedule, prior or concomitant administration of platinum compounds or vinca alcaloids, age and pre-existing peripheral neuropathy of other causes. The most reliable method to assess taxanes neurotoxicity is by clinical examination combined with electrophysiological evaluation. There is currently no effective symptomatic treatment for paclitaxel-associated pain, myalgias and arthralgias. Tricyclic antidepressants and anticonvulsants have been used as symptomatic treatment of neurotoxicity with some measure of success. Therefore, new approaches for prophylaxis against taxanes-induced peripheral neuropathy are needed. Several neuroprotective agents including, thiols, neurotrophic factors, and antioxidants hold promise for their ability to prevent neurotoxicity resulting from taxanes exposure. However, further confirmatory trials are warranted on this important clinical topic. This review critically looks at the pathogenesis, incidence, risk factors, diagnosis, characteristics and management of taxanes-induced peripheral neuropathy. We also highlight areas of future research.

Abstract
BACKGROUND The antiepileptic agent, gabapentin, has been demonstrated to relieve symptoms of peripheral neuropathy due to various etiologies. On the basis of these data, a multicenter, double-blind, placebo-controlled, crossover, randomized trial was conducted to evaluate the effect of gabapentin on symptoms of chemotherapy-induced peripheral neuropathy (CIPN). METHODS Patients with symptomatic CIPN who complained of 'average' daily pain scores of either 1) >/=4 on a 0-10 numerical rating scale (NRS); or 2) >/=1 on the 0-3 Eastern Cooperative Oncology Group neuropathy scale (ENS) were eligible (higher numbers indicate greater severity of symptoms in both scales). Patients were randomized to receive gabapentin (target dose, 2700 mg) or placebo for 6 weeks. Crossover occurred after a 2-week washout period. CIPN-related symptoms were evaluated weekly by questionnaires. Statistical methods followed established methods for crossover designs, including Student t tests to compare average intrapatient differences between treatments and linear models to adjust for potential concomitant covariates. RESULTS There were 115 patients who were randomly assigned to the treatment or control arm. Both groups were well matched by symptoms at study entry. Changes in symptom severity were statistically similar between the 2 groups during the study. Adverse events were mild and similar in both groups. CONCLUSIONS This trial failed to demonstrate any benefit to using gabapentin to treat symptoms caused by CIPN.

Abstract
The current prospective study sought to trace the incidence and severity of cisplatin plus paclitaxel (DDP+P)-induced neuropathy and to determine its clinical and electrophysiological pattern. Furthermore, it was attempted to describe its evolution by following up the course of peripheral neuropathy (PN) during chemotherapy as well as 3 months after its discontinuation. Thirteen adult patients scheduled to be treated with six courses of cumulative DDP+P-based regimens for a non-myeloid malignancy participated in this study. These patients were clinically and electrophysiologically monitored at baseline, during chemotherapy and 3 months after its discontinuation. The severity of PN was summarized by means of a modified PN score. Evidence of PN was disclosed in nine of the 13 patients (69.2%). The mean PN score for patients that manifested some grade of PN was 17.3 +/- 6.1 (range 9-28). All longitudinal comparisons concerning the motor conduction velocities (MCV) variables failed to reach significance. By contrast, comparisons of the mean changes at baseline and each of the follow-up studies revealed a significant decrease in all sensory action potentials examined. The follow-up evaluation performed 3 months after the discontinuation of chemotherapy showed that the DDP+P-induced neuropathy persists and progresses over time. Our results indicate that the majority of patients treated with a DDP+P-based regimen at full dose intensities would manifest an axonal, predominately sensory PN, of mild to moderate severity, which would persist for several months after the discontinuation of chemotherapy.

Abstract
OBJECTIVE To investigate the effects of taxol on the inner ear in a mice model. METHODS This study was performed on 112 ears of 56 albino Swiss mice. All animals underwent baseline auditory brainstem response (ABR) testing bilaterally and baseline Peak Equivalent Sound Pressure Levels (PESPLs) were obtained. The mice were randomly assigned to seven groups consisting of one control and six study groups. The control group received no medications while the mice in groups 1-6 received 1 x 60, 1 x 20, 2 x 20, 3 x 20, 4 x 20 and 5 x 20 mg/kg taxol intraperitoneally. Control ABR assessments were performed 3 weeks after the last dose. The animals were then sacrificed while still anaesthetised and the bullae (cochleae included) were dissected from their temporal bones. Haematoxylin-eosin and Masson's trichrome stains were used to demonstrate connective tissue, and periodic acid Schiff (PAS) stain was used to highlight epithelial elements. RESULTS Significant decreases in the hearing levels were observed in all the groups which received taxol. No correlation was observed between the dose given and the degree of hearing loss. The sections from the control group showed no histopathologic abnormalities while the sections from the study groups demonstrated vacuolisation in the epithelial cells of the spiral limbus, and the stria vascularis, vacuolisation of the fibroblasts and decreasing the number of the fibroblasts in the spiral limbus. CONCLUSION Taxol causes mild to moderate sensorineural hearing loss in mice. Histopathologically, there were degenerative changes in the cochlea resembling the ones that take place in salisylate and interferon alpha 2a ototoxicity which are thought to be reversible. There was no sensory cell loss. The hearing loss begins with doses less than or equal to 20mg/kg and is not dose dependent after this dose. Hearing monitorisation with audiologic evaluation is strongly recommended before and during the use of the drug in human subjects.

Abstract
Peripheral neuropathy induced by cancer chemotherapy represents a large unmet need for patients due to the absence of treatment that can prevent or mitigate this common clinical problem. Chemotherapy-induced peripheral neuropathy (CIPN) diagnosis and management is further compounded by the lack of reliable and standardized means to diagnose and monitor patients who are at risk for, or who are symptomatic from, this complication of treatment. The pathogenesis and pathophysiology of CIPN are not fully elucidated, but there is increasing evidence of damage or interference with tubulin function. The diagnosis of CIPN may present a diagnostic dilemma due to the large number of potential toxic etiologies and conditions, which may mimic some of the clinical features; the diagnosis must be approached with care in such patients. The incidence and severity of CIPN is commonly under-reported by physicians as compared with patients. The development of new and reliable methods for the assessment of CIPN as well as safe and effective treatments to prevent this complication of treatment would represent important medical advancements for cancer patients.

Abstract
BNP7787 (disodium 2,2′-dithio-bis-ethane sulphonate; Tavocept™) is a novel agent developed to protect against cisplatin (cis-diammine-dichloroplatinum(II))-associated chronic toxicities. In this study, we determined the recommended dose of BNP7787 when preceding a fixed dose of cisplatin, the pharmacokinetics (PKs) and the possible reduction of saline hydration. Patients with advanced solid tumours received BNP7787 in escalating doses of 4.1–41 g m−2 as a 15-min intravenous (i.v.) infusion followed by cisplatin 75 mg m−2 as a 60-min i.v. infusion together with pre- and postcisplatin saline hydration in a volume of 2200 ml; cycles were repeated every 3 weeks. PK was carried out using BNP7787, cisplatin and the combination. Twenty-five patients were enrolled in stage I of the study to determine the recommended dose of BNP7787. No dose-limiting toxicity was reached. The highest dose level of 41 g m−2 resulted in a low incidence of grade 2 toxicities, being nausea and vomiting, dry mouth or bad taste and i.v. injection site discomfort. Doses of BNP7787 ⩾18.4 g m−2 did not show a drug interaction between BNP7787 and cisplatin. In stage II of the study, patients received a fixed dose of BNP7787 of 18.4 g m−2 preceding cisplatin and were entered in prespecified reduced saline hydration steps. A total of 21 patients in cohorts of six to nine patients received reduced saline hydration of 1600 ml (step A), 1000 ml (step B) and 500 ml (step C). In step C, two out of six evaluable patients experienced grade 1 nephrotoxicity. Cisplatin acute toxicities in all 46 patients were as expected. Only five patients complained of paresthesias grade 1 and six developed slight audiometric changes. Partial tumour response was observed in four patients and stable disease in 15 patients. In conclusion, BNP7787 was tolerated well up to doses of 41 g m−2. The recommended dose of 18.4 g m−2 enabled safe reduction of the saline hydration schedule for cisplatin to 1000 ml. Further studies will assess whether BNP7787 offers protection against platinum-related late side effects.

Abstract
BACKGROUND We investigated the possible use of clinical signs of chemotherapy-induced peripheral neurotoxicity (CIPN) or of nerve growth factor (NGF) circulating levels to predict the final outcome of CIPN. PATIENTS AND METHODS Sixty-two women affected by locally advanced squamous cervical carcinoma treated with TP (paclitaxel 175 mg/m2 over a 3 h infusion plus cisplatin 75 mg/m2) or TIP (TP plus ifosphamide 5 mg/m2) were examined and scored according to the Total Neuropathy Score (TNS), before and during chemotherapy. RESULTS A correlation with the final severity of CIPN was observed with vibration perception and deep tendon reflex evaluation, while pin sensibility, strength, and autonomic symptoms and signs were not informative. A highly significant correlation existed between the decrease in circulating levels of NGF and the severity of CIPN (r = -0.579; P < 0.001; 95% confidence limits -0.702 to -0.423). However, circulating levels of NGF were not effective as predictors of the final neurological outcome of each patient. CONCLUSION Our study indicates that a precise clinical evaluation of the peripheral nervous system of patients treated with platinum and taxane combination polychemotherapy not only gives reliable information regarding the course of CIPN, but also can be used to predict the final neurological outcome of the treatment.

Abstract
Logically, the choice of any ultimate optimum therapy requires, as well as comparison of the survival outcomes, a comparison of both subjective and objective toxicities in terms of incidence, degree of severity, and duration. Frequently such detail is not collected in large studies. Both cisplatin and paclitaxel are effective but neurotoxic drugs for ovarian cancer. The optimum choice is further complicated in that carboplatin is a possible alternative for cisplatin, being less neurotoxic but having greater hematologic toxicity. Similarly, 3-h and 24-h infusion schedules of paclitaxel have different incidences in opposite directions of hematologic and neurologic toxicities. One hundred fifty two eligible Canadian patients entered in a European-Canadian study that compared paclitaxel-cisplatin (PT, 79) patients with cyclophosphamide-cisplatin (PC, 73 patients) had both subjective and objective neurotoxicity data collected from treatment initiation to disease progression. Incidence, degree, and duration (compared in an analogous way to remission durations) of neurotoxicity were compared in the two arms to quantify the additional paclitaxel toxicity. No significant differences were found for motor toxicity, motor impairment, hearing impairment, or insomnia. For sensory changes during treatment, toxicity (all grades, 91% vs. 49%; grade 3 or higher, 29% vs. 3%) incidence, subjective impairment (a little or more, 89% vs. 40%; lots, 54% vs. 11%) incidence, and toxicity duration (all grades only), and impairment durations (both degrees) were all worse for PT. During follow-up, only the incidence of all-grade sensory toxicity was worse and this was not reflected by any other parameters. We conclude that paclitaxel adds considerably, but only temporarily, to the sensoy neurotoxicity of cisplatin.

Abstract
Chemotherapy-induced encephalopathies occur in a variety of clinical settings and the most detailed accounts have been described following combination methotrexate and radiation therapy. The case described herein developed severe encephalopathy following a high-dose chemotherapy protocol used in the treatment of metastatic carcinoma of the breast. Visual symptoms developed 3 weeks after completing high-dose chemotherapy and peripheral blood hematopoietic stem cell transplantation. Over the next several weeks, additional neurologic deficits developed and continued to progress despite various treatment interventions. Diffuse deep gray matter damage was identified on MR imaging and a brain biopsy revealed pathological findings similar in many respects to those described for methotrexate/radiation, cisplatin, BCNU and/or 5 FU/levamisole-related leukoencephalopathy. The patient succumbed to complications resulting from the CNS disorder, 8 weeks after the onset of symptoms. This case is unusual for two reasons. First, the patient developed severe encephalopathy following a high-dose chemotherapy protocol commonly used in the treatment of metastatic breast carcinoma and second, the encephalopathy involved primarily deep gray matter structures rather than white matter.

Abstract
LY355703 is a synthetic derivative of the marine cryptophycins, cytotoxic agents which induce mitotic arrest by binding at the microtubule vinca binding domain. Promising preclinical features of LY355703 were the 40-400 greater potency than paclitaxel or vinca alkaloids, the broad spectrum of antitumor activity in xenografts and the antitumour activity in multidrug resistant (MDR)-expressing murine tumours. Aims of this study were to define the maximum tolerated dose (MTD) and the dose recommended for Phase II, the pattern of toxicity, the pharmacokinetic profile and to document hints of antitumour activity of LY355703 given as 2-h infusion on day 1 every 3 weeks (Study 1) or, later on, on days 1, 8 and 15 every 4 weeks (Study 2). The latter weekly regimen was selected because of the acute dose-related toxicity reported in Study 1. The dose was escalated using a modified Continual Reassessment Method. Pharmacokinetic studies were performed on day 1 of cycle 1 in both studies; LY355703 plasma concentrations were assessed by liquid chromatography with tandem mass spectrometry. A total of 35 adult patients with solid tumours entered Study 1; the dose was escalated from 0.1 to 1.92 mg/m(2); at this dose 2 of 5 patients presented grade 3 neuropathy and myalgias; 1.48 mg/m(2) was then recommended for Phase II study. A total of 8 patients were treated in Study 2 at 1 mg/m(2); cumulative long-lasting neuroconstipation and neurosensory toxicity precluded the completion of the cycle in 9 out of 15 cycles; the clinical development of the weekly regimen was then discontinued. Other toxicities included cardiac dysrhythmia and mild alopecia. Pharmacokinetics of LY355703 appeared to be linear over the dose range studied. The administration of LY355703 on a 3-week schedule is associated with an acute dose-dependent peripheral neuropathy and myalgia of high interpatient variability for which possible risk factors and pharmacokinetic correlates could not be identified.

Abstract
When treating patients for metastatic cancer, there is always a balance between the benefits of treatment and resulting side-effects. Peripheral sensory neuropathy (PSN) is a side-effect of many anticancer agents used in routine practice. Oxaliplatin is a relatively new agent currently licensed in over 50 countries including France, Germany and the UK for the treatment of metastatic colorectal cancer. Although it is a new agent, it is from the same family of drugs as cisplatin, an agent that has been used for many years. PSN is the most commonly discussed side-effect associated with oxaliplatin. Oxaliplatin-induced PSN is characterized by two distinct syndromes: a transient acute dysaesthesia and a cumulative distal neurotoxicity. Importantly, both are generally reversible after stopping treatment. Oxaliplatin-induced acute PSN is triggered and exacerbated by cold and can be greatly reduced in affected patients simply by avoiding cold conditions. Oxaliplatin-induced cumulative PSN may also be managed by temporary cessation of treatment.

Abstract
PURPOSE To study feasibility and efficacy of a new salvage regimen in patients with relapsed and/or refractory germ cell tumors. PATIENTS AND METHODS Between May 1995 and February 1997, 80 patients were entered onto a phase II study. Conventional-dose salvage treatment with three cycles of paclitaxel 175 mg/m(2), ifosfamide 5 x 1.2 g/m(2), and cisplatin 5 x 20 mg/m(2) (TIP) was followed by one cycle of high-dose chemotherapy (HDCT) with carboplatin 500 mg/m(2) x 3, etoposide 600 mg/m(2) x 4, and thiotepa 150 to 250 mg/m(2) x 3 (CET). In 23 patients, one additional cycle of paclitaxel 175 mg/m(2) and ifosfamide 5 g/m(2) (TI) was given immediately before TIP to improve stem-cell mobilization. RESULTS Fifty-five (69%) of 80 patients responded to TIP, 24 (30%) of 80 patients had stable disease (n = 5) or tumor progression (n = 19), and one patient died. Only 62 (78%) of 80 patients received subsequent HDCT. Among those, 41 (66%) of 62 patients responded and 20 (32%) of 62 patients had stable disease (n = 3) or tumor progression (n = 17). One patient died after HDCT from multiorgan failure. Survival probabilities at 3 years were 30% for overall and 25% for event-free survival. Peripheral neurotoxicity with sensorimotor impairment grade 2 through 4 in 29%, paresthesias grade 2 through 4 in 24%, and skin toxicity grade 2 through 3 in 15% of patients were the most relevant side effects. CONCLUSION Treatment with TIP followed by high-dose CET is feasible and can induce long-term remissions in 25% of patients with relapsed or refractory germ cell tumors. Peripheral nervous toxicity in approximately one third of patients is a disadvantage of this salvage strategy.

Abstract
Chronic pain, lymphoedema, post-irradiation neuropathy and other symptoms are reported in as many as 75% of women following breast cancer treatment. This study examined pain and sensory abnormalities in women following breast cancer surgery. Sensory tests were carried out on operated and contralateral sides in 15 women with spontaneous pain and sensory abnormalities and 11 pain-free women. Testing included the VAS score of spontaneous pain, detection and pain threshold to thermal and mechanical stimuli, temporal summation to repetitive heat and pinprick stimuli, and assessment of skin blood flow during repetitive brush and pinprick stimulation. Sensory threshold to pinprick and thermal stimuli was significantly higher on the operated side in both groups while pressure pain threshold was significantly lower in pain patients on the operated side compared to the contralateral side. No side to side difference was seen in pressure pain threshold in the pain-free group. Evoked pain intensity to repetitive stimuli at 0.2 and 2.0 Hz was significantly higher on the operated side in pain patients compared to the control area while no such difference was seen in pain-free patients. Cutaneous blood flow measured by laser Doppler (flux) was significantly higher when the skin was tapped at 2.0 Hz on the operated side compared to contralaterally in pain patients, while no side to side difference was seen in pain-free patients. Pinprick-evoked pain was correlated to spontaneous pain but not to flux. Spontaneous pain was not correlated to flux. Sensitization seems to be a feature in breast cancer-operated women with pain, but not in pain-free women.

Abstract
We assessed the peripheral neuropathic changes induced by biweekly combination chemotherapy including paclitaxel 100-165 mg/m2 (in a 3-h infusion), epirubicin 75 mg/m2 and cisplatin 50 mg/m2 (TEC) in patients with advanced ovarian cancer. Neurologic evaluation, including a standardized questionnaire, bed-side neurological examination, and quantitative determination of vibratory perception thresholds (VPT) and grip strength took place before therapy, after 3 and 6 cycles, and thereafter whenever possible. During chemotherapy all patients received granulocyte colony-stimulating factor from days 2 to 12. Pretreated patients received amifostine two times, before epirubicin and before cisplatin administration. Neuropathic symptoms developed in 11/13 non-pretreated patients and in 7/9 chemotherapy-pretreated patients. Neuropathic signs developed in all patients. Neuropathic symptoms and signs were predominantly sensory in character. VPT changes developed primarily in the feet. According to National Cancer Institute of Canada Common Toxicity Criteria, grade 3 peripheral neuropathy after 6 cycles developed in 1/6 and 2/4 non-pretreated patients who received TEC containing paclitaxel 150 and 165 mg/m2, respectively. We conclude that peripheral neuropathy is dose-limiting in chemonaïve patients treated with biweekly TEC combination chemotherapy, at paclitaxel dose level 165 mg/m2 in a 3-h intravenous administration.

Abstract
Peripheral neurotoxicity is a dose-limiting side-effect for a number of effective chemotherapeutic agents, including platinum compounds, taxanes, and vinca alkaloids. New experimental chemotherapy drugs that cause neuropathy include suramin and Dolostatin-10. A better understanding of cellular mechanisms will lead to novel treatment strategies that will protect neurons without decreasing therapeutic efficacy.
