Abstract
In recent years, indolylglyoxylamide-based derivatives have received much attention due to their application in drug design and discovery, leading to the development of a wide array of compounds that have shown a variety of pharmacological activities. Combining the indole nucleus, already validated as a "privileged structure," with the glyoxylamide function allowed for an excellent template to be obtained that is suitable to a great number of structural modifications aimed at permitting interaction with specific molecular targets and producing desirable therapeutic effects. The present review provides insight into how medicinal chemists have elegantly exploited the indolylglyoxylamide moiety to obtain potentially useful drugs, with a particular focus on compounds exhibiting activity in in vivo models or reaching clinical trials. All in all, this information provides exciting new perspectives on existing data that can be useful in further design of indolylglyoxylamide-based molecules with interesting pharmacological profiles. The aim of this report is to present an update of collection data dealing with the employment of this moiety in the rational design of compounds that are able to interact with a specific target, referring to the last 20 years.

Tetrodotoxin for Chemotherapy-Induced Neuropathic Pain: A Randomized, Double-Blind, Placebo-Controlled, Parallel-Dose Finding Trial. Toxins (Basel) 2021; 13:toxins13040235. [PMID: 33805908 PMCID: PMC8064362 DOI: 10.3390/toxins13040235] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2021] [Revised: 03/20/2021] [Accepted: 03/23/2021] [Indexed: 12/15/2022] Open
Abstract
Tetrodotoxin (TTX) has emerged as a potentially efficacious agent for chemotherapy-induced neuropathic pain (CINP), a prevalent, debilitating condition often resistant to analgesics. This randomized, double-blind, dose-finding study was undertaken to explore safety and trends in efficacy of four TTX doses and to identify a dose for further study. One hundred and twenty-five patients with taxane- or platinum-related CINP received subcutaneous placebo or TTX (7.5 µg twice daily (BID), 15 µg BID, 30 µg once daily (QD), 30 µg BID) for four consecutive days. Primary outcome measure was average patient-reported Numeric Pain Rating Scale (NPRS) score during Days 21–28 post-treatment. Changes in mean NPRS score were not statistically different between cohorts, due to small trial size and influence of a few robust placebo responders. Cumulative responder analysis showed significant difference from placebo with 30 µg BID cohort using the maximum response at any timepoint (p = 0.072), 5-day (p = 0.059), 10-day (p = 0.027), and 20-day (p = 0.071) rolling averages. In secondary quality of life (QOL) outcomes, 30 µg BID cohort also differed significantly from placebo in a number of SF-36 and CIPN20 subscales. Most adverse events (AE) were mild or moderate with oral paresthesia (29.6%) and oral hypoesthesia (24.8%) as most common.

Abstract
This review summarizes the adverse effects on the central and/or peripheral nervous systems that may occur in response to antineoplastic drugs. In particular, we describe the neurotoxic side effects of the most commonly used drugs, such as platinum compounds, doxorubicin, ifosfamide, 5-fluorouracil, vinca alkaloids, taxanes, methotrexate, bortezomib and thalidomide. Neurotoxicity may result from direct action of compounds on the nervous system or from metabolic alterations produced indirectly by these drugs, and either the central nervous system or the peripheral nervous system, or both, may be affected. The incidence and severity of neurotoxicity are principally related to the dose, to the duration of treatment, and to the dose intensity, though other factors, such as age, concurrent pathologies, and genetic predisposition may enhance the occurrence of side effects. To avoid or reduce the onset and severity of these neurotoxic effects, the use of neuroprotective compounds and/or strategies may be helpful, thereby enhancing the therapeutic effectiveness of antineoplastic drug.

Abstract
Several thiophene featuring compounds are known for their promising antiproliferative activity. Prompted by the urgent need to identify new potent anticancer agents, 16 compounds of benzamides, benzylamines, and urea analogues incorporating a cyclohepta[b]thiophene scaffold were synthesized and biologically evaluated with a cell proliferation assay using the A549 nonsmall cell lung cancer cell line. Compound 17 demonstrated both potent and broad-spectrum anticancer activity with submicromolar 50% growth inhibition (GI50) values. It also showed superior antiproliferative activity (vs nocodazole) in OVACAR-4, OVACAR-5, CAKI-1, and T47D cell lines with GI50 values of 2.01 (vs 22.28), 2.27 (vs 20.75), 0.69 (vs 1.11), and 0.362 (vs 81.283) μM, respectively. Additionally, compound 17 displayed minimal cytotoxicity based on 50% lethal concentration (LC50) values toward all tested cell lines. Further cell-based mechanistic studies of compound 17 revealed its ability to induce cell cycle arrest of A549 cells as evidenced by dose dependent G2/M accumulation. Furthermore, induction of early apoptosis along with activation of caspase 3, 8, and 9 were confirmed in A549 cells treated with compound 17. Targeting tubulin polymerization may explain the mechanism of the antiproliferative activity of compound 17 based on cell cycle analysis, detected apoptosis, and in vitro inhibition of tubulin polymerization. In vitro data were further supported by in vivo antitumor efficacy studies of compound 17 in a CT26 murine model for which the results showed a reduction in the tumor growth compared to untreated mice. Overall, compound 17 has the potential to function as a promising candidate for further development of potent anticancer chemotherapeutics.

Abstract
Microtubule (MT) inhibitors show anti-cancer activity in a wide range of tumors in vitro and demonstrate high clinical efficacy. To date they are routinely included into many chemotherapeutic regimens. While the mechanisms of MT inhibitors’ interactions with tubulin have been well-established, the relationship between their concentration and effect on neoplastic cells is not completely understood. The common notion is that tumor cells are most vulnerable during division and all MT inhibitors block them in mitosis and induce mitotic checkpoint-associated cell death. At the same time multiple evidence of more subtle effects of lower doses of MT inhibitors on cell physiology exist. The extent of efficacy of the low-dose MT inhibitor treatment and the mechanisms of resulting cell death currently present a critical issue in oncology. The prospect of MT inhibitor dose reduction is promising as protocols at higher concentration have multiple side effects. We assessed cell cycle changes and cell death induced by MT inhibitors (paclitaxel, nocodazole, and vinorelbine) on human lymphoid B-cell lines in a broad concentration range. All inhibitors had similar accumulation effects and demonstrated “trigger” concentrations that induce cell accumulation in G2/M phase. Concentrations slightly below the “trigger” promoted cell accumulation in sub-G1 phase. Multi-label analysis of live cells showed that the sub-G1 population is heterogeneous and may include cells that are still viable after 24 h of treatment. Effects observed were similar for cells expressing Tat-protein. Thus cell cycle progression and cell death are differentially affected by high and low MT inhibitor concentrations.

Anticancer activity of a novel small molecule tubulin inhibitor STK899704. PLoS One 2017; 12:e0173311.

Abstract
We have identified the small molecule STK899704 as a structurally novel tubulin inhibitor. STK899704 suppressed the proliferation of cancer cell lines from various origins with IC50 values ranging from 0.2 to 1.0 μM. STK899704 prevented the polymerization of purified tubulin in vitro and also depolymerized microtubule in cultured cells leading to mitotic arrest, associated with increased Cdc25C phosphorylation and the accumulation of both cyclin B1 and polo-like kinase 1 (Plk1), and apoptosis. Unlike many anticancer drugs such as Taxol and doxorubicin, STK899704 effectively displayed antiproliferative activity against multidrug-resistant cancer cell lines. The proposed binding mode of STK899704 is at the interface between αβ-tubulin heterodimer overlapping with the colchicine-binding site. Our in vivo carcinogenesis model further showed that STK 899704 is potent in both the prevention and regression of tumors, remarkably reducing the number and volume of skin tumor by STK899704 treatment. Moreover, it was significant to note that the efficacy of STK899704 was surprisingly comparable to 5-fluorouracil, a widely used anticancer therapeutic. Thus, our results demonstrate the potential of STK899704 to be developed as an anticancer chemotherapeutic and an alternative candidate for existing therapies.

Abstract
Proteasomal system plays an important role in protein turnover, which is essential for homeostasis of cells. Besides degradation of oxidized proteins, it is involved in the regulation of many different signaling pathways. These pathways include mainly cell differentiation, proliferation, apoptosis, transcriptional activation and angiogenesis. Thus, proteasomal system is a crucial target for treatment of several diseases including neurodegenerative diseases, cystic fibrosis, atherosclerosis, autoimmune diseases, diabetes and cancer. Over the last fifteen years, proteasome inhibitors have been tested to highlight their mechanisms of action and used in the clinic to treat different types of cancer. Proteasome inhibitors are mainly used in combinational therapy along with classical chemo-radiotherapy. Several studies have proved their significant effects but serious side effects such as peripheral neuropathy, limits their use in required effective doses. Recent studies focus on peripheral neuropathy as the primary side effect of proteasome inhibitors. Therefore, it is important to delineate the underlying mechanisms of peripheral neuropathy and develop new inhibitors according to obtained data. This review will detail the role of proteasome inhibition in cancer therapy and development of peripheral neuropathy as a side effect. Additionally, new approaches to prevent treatment-limiting side effects will be discussed in order to help researchers in developing effective strategies to overcome side effects of proteasome inhibitors.

Abstract
BACKGROUND Natural products including Agrimonia eupatoria are considered an incomparable source of molecular diversity that has led to the medicines, especially for pain treatment. To investigate the antinociception of Agrimonia eupatoria, we examined its activity in a rat model of cisplatin neuropathy. MATERIALS AND METHODS Male Sprague-Dawley rats received intraperitoneal (i.p.) cisplatin twice a week at a dose of 2 mg/kg (cumulative dose, 20 mg/kg) for 4 weeks. Before each injection, 2 ml of sterile saline solution was given subcutaneously to prevent renal damage via hyperhydration. The mice were treated with gabapetin as a positive control drug with a 100mg/kg intraperitoneal injection. A. eupatoria extract of 200mg/kg was solved in saline and then treated by oral administration. RESULTS The mice treated with A. eupatoria showed lower withdrawal duration in the pin-prick and plantar tests, and a higher withdrawal threshold in the paw-withdrawal threshold test as compared to control animals in a cisplatin-induced neuropathic model. In the case of cold-allodynia, A. eupatoria treatment increased paw-withdrawal duration in a chemical test. A. eupatoria showed a more outstanding effect than gabapentin in all used tests for preventing cisplatin-induced nerve injury for 4 weeks. CONCLUSIONS Our results suggest that A. eupatoria extract showed an antinociceptive effect in the pin-prick test, plantar test, and paw-withdrawal threshold test using a cisplatin-induced neuropathic rat model.

Abstract
PURPOSE To gain insight into the association of physical activity (PA), chemotherapy-induced peripheral neuropathy (CIPN) and health-related quality of life among colorectal cancer survivors, up to 11 years after diagnosis. METHODS Data of the second data wave of a Dutch prospective population-based survey among colorectal cancer survivors diagnosed between 2000 and 2009 as registered by the Eindhoven Cancer Registry was used. Eighty-three percent (n = 1648) of patients filled out the EORTC QLQ-C30 and the EORTC QLQ-CIPN20 of which 506 patients (31%) were treated with chemotherapy. RESULTS Treatment with chemotherapy was associated with a higher percentage of patients reporting CIPN symptoms regardless of PA. Furthermore, not meeting the Dutch PA guideline of 150 min of moderate to vigorous PA a week was associated with more CIPN among patients treated with chemotherapy. Also patients not treated with chemotherapy reported CIPN-like symptoms, especially when not meeting the PA guideline. Statistically significant and clinically relevant worse scores on almost all EORTC QLQ-C30 subscales were reported by those not meeting the PA guideline compared to those who did meet the guideline, regardless of CIPN symptoms. However, these differences were more pronounced in the group with many CIPN symptoms (e.g. upper 30%). IMPLICATIONS FOR CANCER SURVIVORS Alertness among health care professionals and patients for the importance of PA is warranted, as meeting the PA guideline was associated with less CIPN-like symptoms and a higher health-related quality of life regardless of treatment with chemotherapy.

Abstract
Peripheral neuropathy is a common adverse effect of bortezomib-based chemotherapy. In this study we have investigated the role played by subtype 5 of metabotropic receptors in bortezomib induced peripheral neuropathy. Rats were administered with bortezomib three times weekly at 0.20 mg/kg for a total of 4 weeks in presence or absence of mGluR5 antagonist MPEP. The animals were submitted to paw-pressure test and tail sensory nerve conduction measurement more times during the treatment and follow-up. Bortezomib treatment induced a progressively increasing hyperalgesia in rat which was accompanied by a significant reduction in sensory nerve conduction velocity (SNCV). MPEP prevented the emergence of bortezomib-induced pain and counteracted SNCV reduction when co-administered with bortezomib treatment. Spinal extracellular glutamate levels increased in rats treated with bortezomib. Bortezomib-induced onset of the hyperalgesia and SNCV decrease could be prevented by agents that promote the reuptake of glutamate maintaining spinal glutamate at basal level. Our data support the manipulation of the glutamatergic system through the mGluR5 receptor in bortezomib induced peripheral neuropathy. The use of antagonists at the mGluR5, initiated at the same time as bortezomib-chemotherapy, might reduce the number of patients who develop painful peripheral chemo-neuropathy.

Abstract
Introduction Gemcitabine is a pyrimidine nucleoside analog that becomes triphosphorylated and in this form it competitively inhibits cytidine incorporation into DNA strands. Diphosphorylated gemcitabine irreversibly inhibits ribonucleotide reductase thereby preventing deoxyribonucleotide synthesis. Functioning as a potent chemotherapeutic, gemcitabine decreases neoplastic cell proliferation and induces apoptosis which accounts for its effectiveness in the clinical treatment of several leukemia and carcinoma cell types. A brief plasma half-life due to rapid deamination, chemotherapeuticresistance and sequelae restricts gemcitabine utility in clinical oncology. Selective “targeted” gemcitabine delivery represents a molecular strategy for prolonging its plasma half-life and minimizing innocent tissue/organ exposure. Methods A previously described organic chemistry scheme was applied to synthesize a UV-photoactivated gemcitabine intermediate for production of gemcitabine-(C4-amide)-[anti-HER2/neu]. Immunodetection analysis (Western-blot) was applied to detect the presence of any degradative fragmentation or polymerization. Detection of retained binding-avidity for gemcitabine-(C4-amide)-[anti-HER2/neu] was determined by cell-ELISA using populations of chemotherapeutic-resistant mammary adenocarcinoma (SKBr-3) that highly over-express the HER2/neu trophic membrane receptor. Anti-neoplastic cytotoxicity of gemcitabine-(C4-amide)-[anti-HER2/neu] and the tubulin/microtubule inhibitor, griseofulvin was established against chemotherapeutic-resistant mammary adenocarcinoma (SKBr-3). Related investigations evaluated the potential for gemcitabine-(C4-amide)-[anti-HER2/neu] in dual combination with griseofulvin to evoke increased levels of anti-neoplastic cytotoxicity compared to gemcitabine-(C4-amide)-[anti-HER2/neu]. Results Covalent gemcitabine-(C4-amide)-[anti-HER2/neu] immunochemotherapeutic and griseofulvin exerted anti-neoplastic cytotoxicity against chemotherapeutic-resistant mammary adenocarcinoma (SKBr-3). Covalent gemcitabine-(C4-amide)-[anti-HER2/neu] immunochemotherapeutic or gemcitabine in dual combination with griseofulvin created increased levels of anti-neoplastic cytotoxicity that were greater than was attainable with gemcitabine-(C4-amide)-[anti-HER2/neu] or gemcitabine alone. Conclusion Gemcitabine-(C4-amide)-[anti-HER2/neu] in dual combination with griseofulvin can produce enhanced levels of anti-neoplastic cytotoxicity and potentially provide a basis for treatment regimens with a wider margin-of-safety. Such benefits would be possible through the collective properties of; [i] selective “targeted” gemcitabine delivery; [ii] relatively lower toxicity of griseofulvin compared to many if not most conventional chemotherapeutics; [iii] reduced total dosage requirements faciliated by additive or synergistic anti-cancer properties; and [iv] differences in sequelae for gemcitabine-(C4-amide)-[anti-HER2/neu] compared to griseofulvin functioning as a tubulin/microtubule inhibitor.

Abstract
Immunochemotherapeutics, epirubicin-(C3-amide)-SS-[anti-HER2/neu] with an internal disulfide bond, and epirubicin-(C3-amide)-[anti-HER2/neu] were synthesized utilizing succinimidyl 2-[(4,4'-azipentanamido) ethyl]-1,3'-dithioproprionate or succinimidyl 4,4-azipentanoate respectively. Western blot analysis was used to determine the presence of any immunoglobulin fragmentation or IgG-IgG polymerization. Retained HER2/neu binding characteristics of epirubicin-(C3-amide)-[anti-HER2/neu] and epirubicin-(C3-amide)-SS-[anti-HER2/neu] were validated by cell-ELISA using a mammary adenocarcinoma (SKBr-3) population that highly over-expresses trophic HER2/neu receptor complexes. Cytotoxic anti-neoplastic potency of epirubicin-(C3-amide)-[anti-HER2/neu] and epirubicin-(C3-amide)-SS-[anti-HER2/neu] between epirubicin-equivalent concentrations of 10-10 M and 10-6 M was determined by measuring the vitality/proliferation of chemotherapeutic-resistant mammary adenocarcinoma (SKBr-3 cell type). Cytotoxic anti-neoplastic potency of benzimidazoles (albendazole, flubendazole, membendazole) and griseofulvin were assessed between 0-to-2 μg/ml and 0-to-100 μg/ml respectively while mebendazole and griseofulvin were analyzed at fixed concentrations of 0.35 μg/ml and 35 g/ml respectively in dual combination with gradient concentrations of epirubicin-(C3-amide)-[anti-HER2/neu] and epirubicin-(C3-amide)-SS-[anti-HER2/neu]. Cytotoxic anti-neoplastic potency for epirubicin-(C3-amide)-[anti-HER2/neu] and epirubicin-(C3-amide)-SS-[anti-HER2/neu] against chemotherapeutic-resistant mammary adenocarcinoma (SKBr-3) was nearly identical at epirubicin-equivalent concentrations of 10-10 M and 10-6 M. The benzimadazoles also possessed cytotoxic anti-neoplastic activity with flubendazole and albendazole being the most and least potent respectively. Similarly, griseofulvin had cytotoxic anti-neoplastic activity and was more potent than methylselenocysteine. Both mebendazole and griseofulvin when applied in dual combination with either epirubicin-(C3-amide)-[anti-HER2/neu] or epirubicin-(C3-amide)-SS-[anti-HER2/neu] produced enhanced levels of cytotoxic anti-neoplatic potency.

Abstract
CONTEXT Persistent pain after treatment for breast cancer (PPBCT) is a common side effect of breast cancer treatment, with prevalence as high as 50%. It is predominantly a neuropathic condition. OBJECTIVES The aim of this cross-sectional, questionnaire-based study was to examine the emotional characteristics of patients with PPBCT in long-term breast cancer patients. A secondary objective was to characterize the risk factors and severity of that pain. METHODS From March 1, 2010 to April 9, 2010, long-term follow-up patients were invited to complete a questionnaire. This recorded their surgical and demographic data and ascertained whether they had PPBCT. If the patient had pain, she completed a range of validated self-report questionnaires and questions about the nature of the pain, including a visual analogue scale. RESULTS One hundred eleven patients completed the questionnaire; 33 (29.7%) patients reported chronic pain at a median time of 64 months postoperatively (interquartile range 54.25). Patients with persistent pain were not significantly more anxious (t(105)=-0.369, P=0.713) or depressed (t(105)=0.713, P=0.507) than patients without pain. Patients with constant pain compared with intermittent pain were significantly more anxious (t(25)=-3.460, P=0.002). Preoperative pain conferred a fivefold increased risk of PPBCT (odds ratio [OR]=5.17, 95% confidence interval [CI]=1.79-14.97, P=0.002); chemotherapy conferred a threefold increased risk (OR=3.004, 95% CI=1.22-7.40, P=0.017). CONCLUSION We have shown significant numbers of patients suffer from PPBCT. At a median time of 64.5 months, women with pain are not significantly more anxious or depressed than women without pain. Preoperative pain and chemotherapy have been highlighted as risk factors.

Abstract
Anthracyclines and taxanes have remarkable anticancer efficacy, but have poor selectivity and high toxicity. Targeted delivery of chemotherapeutics has emerged as a strategy to achieve higher drug levels at the tumor site, to spare noncancerous tissue and potentially to use lower systemic drug doses, thus preventing side effects. In this study, we targeted the HER2 receptor using the monoclonal antibody (mAb) Herceptin (Trastuzumab) chemically conjugated to Doxorubicin or Taxol. In vitro, drug-Herceptin conjugates exhibited cytotoxicity comparable to equimolar concentrations of free drugs, with the benefit that the cytotoxicity of the conjugates was selective for cells expressing the HER2 target. In vivo, treatment of tumor-bearing mice with Taxol-Herceptin conjugates had a reduction of primary tumors comparable to equivalent doses of free drugs. However, Taxol-Herceptin conjugates significantly reduced metastasis compared with equivalent doses of free drugs. Thus, the data support the concept that conjugates might target metastasis better than primary tumors. This would offer a potential therapeutic approach for management of metastatic breast cancer.

Abstract
Axonal degeneration is a molecular self-destruction cascade initiated following traumatic, toxic, and metabolic insults. Its mechanism underlies a number of disorders including hereditary and diabetic neuropathies and the neurotoxic side effects of chemotherapy drugs. Molecules that promote axonal degeneration could represent potential targets for therapy. To identify such molecules, we designed a screening platform based on intoxication of Drosophila larvae with paclitaxel (taxol), a chemotherapeutic agent that causes neuropathy in cancer patients. In Drosophila, taxol treatment causes swelling, fragmentation, and loss of axons in larval peripheral nerves. This axonal loss is not due to apoptosis of neurons. Taxol-induced axonal degeneration in Drosophila shares molecular execution mechanisms with vertebrates, including inhibition by both NMNAT (nicotinamide mononucleotide adenylyltransferase) expression and loss of wallenda/DLK (dual leucine zipper kinase). In a pilot RNAi-based screen we found that knockdown of retinophilin (rtp), which encodes a MORN (membrane occupation and recognition nexus) repeat-containing protein, protects axons from degeneration in the presence of taxol. Loss-of-function mutants of rtp replicate this axonal protection. Knockdown of rtp also delays axonal degeneration in severed olfactory axons. We demonstrate that the mouse ortholog of rtp, MORN4, promotes axonal degeneration in mouse sensory axons following axotomy, illustrating conservation of function. Hence, this new model can identify evolutionarily conserved genes that promote axonal degeneration, and so could identify candidate therapeutic targets for a wide-range of axonopathies.

Abstract
Despite aggressive treatment regimes, glioma remains a largely fatal disease. Current treatment limitations are attributed to the precarious locations within the brain where such tumors grow, their highly infiltrative nature precluding complete resection and lack of specificity among agents capable of attenuating their growth. Here, we show that in vitro, glioma cells of diverse origins internalize a peptide encompassing a tubulin-binding site (TBS) on the neurofilament light protein. The internalized peptide disrupts the microtubule network, inhibits migration and proliferation, and leads to apoptosis. Using an intracerebral transplant model, we show that most, if not all, of these responses to peptide exposure also occur in vivo. Notably, a single intratumor injection significantly attenuates tumor growth, while neither peptide uptake nor downstream consequences are observed elsewhere in the host nervous system. Such preferential uptake suggests that the peptide may have potential as a primary or supplementary glioblastoma treatment modality by exploiting its autonomous microtubule-disrupting activity or engaging its capacity to selectively target glioma cells with other cell-disrupting cargos.

Abstract
BACKGROUND Chemotherapy-induced peripheral neuropathy (CIPN) is characterized by numbness, tingling, and shooting/burning pain. This analysis was performed to describe the relationship between numbness, tingling, and shooting/burning pain in patients with CIPN, as reported using the EORTC QLQ-CIPN20 (CIPN20). METHODS Baseline CIPN20 data were provided for all patients on a prospective trial designed to treat patients with bothersome CIPN. Baseline frequencies for the items on the CIPN20 are primarily described by descriptive statistics and histograms, with correlational analyses between individual items. RESULTS A majority of the 199 patients accrued to this study reported "quite a bit" to "very much" numbness (57%) or tingling (63%) in the hands compared to "a little" or "not at all" (numbness (43%), tingling (38%)). Fewer patients reported "quite a bit" to "very much" shooting/burning pain in the hands (18%). Numbness and tingling in the hands were highly correlated (r = 0.69), while neither were highly correlated with shooting/burning pain. Similar results were observed in the feet. More severe ratings for tingling and shooting/burning pain were ascribed to the lower extremities, as opposed to the upper extremities. CONCLUSIONS In patients with CIPN, severe sensory neuropathy symptoms (numbness, tingling) commonly exist without severe neuropathic pain symptoms (shooting/burning pain), while the reverse is not common. Symptoms in the feet should be evaluated distinctly from those in the hands as the experience of symptoms is not identical, for individual patients, in upper versus lower extremities.

Abstract
CONTEXT Several chemotherapy agents induce polyneuropathy that is painful for some patients, but not for others. We assumed that these differences might be attributable to varying patterns of pain modulation. OBJECTIVES The aim of the present study was to evaluate pain modulation in such patients. METHODS Twenty-seven patients with chemotherapy-induced polyneuropathy were tested for detection thresholds (cold, warm, and mechanical) in both the forearm and foot, as well as for heat pain threshold, mechanical temporal summation (TS), and conditioned pain modulation (CPM; also known as the diffuse noxious inhibitory control-like effect), which were tested in the upper limbs. RESULTS Positive correlations were found between clinical pain levels and both TS (r=0.52, P=0.005) and CPM (r=0.40, P=0.050) for all patients. In addition, higher TS was associated with less efficient CPM (r=0.56, P=0.004). The group of patients with painful polyneuropathy (n=12) showed a significantly higher warm detection threshold in the foot (P=0.03), higher TS (P<0.01), and less efficient CPM (P=0.03) in comparison to the group with nonpainful polyneuropathy. CONCLUSION The painfulness of polyneuropathy is associated with a "pronociceptive" modulation pattern, which may be primary to the development of pain. The higher warm sensory thresholds in the painful polyneuropathy group suggest that the severity of polyneuropathy may be another factor in determining its painfulness.

Abstract
BACKGROUND Chemotherapy-induced peripheral neuropathy (CIPN) is a troublesome chronic symptom that has no proven pharmacologic treatment. The purpose of this double-blind randomized placebo-controlled trial was to evaluate a novel compounded topical gel for this problem. METHODS Patients with CIPN were randomized to baclofen 10 mg, amitriptyline HCL 40 mg, and ketamine 20 mg in a pluronic lecithin organogel (BAK-PLO) versus placebo (PLO) to determine its effect on numbness, tingling, pain, and function. The primary endpoint was the baseline-adjusted sensory subscale of the EORTC QLQ-CIPN20, at 4 weeks. RESULTS Data in 208 patients reveal a trend for improvement that is greater in the BAK-PLO arm over placebo in both the sensory (p = 0.053) and motor subscales (p = 0.021). The greatest improvements were related to the symptoms of tingling, cramping, and shooting/burning pain in the hands as well as difficulty in holding a pen. There were no undesirable toxicities associated with the BAK-PLO and no evidence of systemic toxicity. CONCLUSION Topical treatment with BAK-PLO appears to somewhat improve symptoms of CIPN. This topical gel was well tolerated, without evident systemic toxicity. Further research is needed with increased doses to better clarify the clinical role of this treatment in CIPN.

Abstract
Chemotherapy-induced neurotoxicity is a significant problem associated with successful treatment of many cancers. Tubulin is a well-established target of antineoplastic therapy; however, tubulin-targeting agents, such as paclitaxel and the newer epothilones, induce significant neurotoxicity. Eribulin mesylate, a novel microtubule-targeting analogue of the marine natural product halichondrin B, has recently shown antineoplastic activity, with relatively low incidence and severity of neuropathy, in metastatic breast cancer patients. The mechanism of chemotherapy-induced neuropathy is not well understood. One of the main underlying reasons is incomplete characterization of pathology of peripheral nerves from treated subjects, either from patients or preclinically from animals. The current study was conducted to directly compare, in mice, the neuropathy-inducing propensity of three drugs: paclitaxel, ixabepilone, and eribulin mesylate. Because these drugs have different potencies and pharmacokinetics, we compared them on the basis of a maximum tolerated dose (MTD). Effects of each drug on caudal and digital nerve conduction velocity, nerve amplitude, and sciatic nerve and dorsal root ganglion morphology at 0.25 × MTD, 0.5 × MTD, 0.75 × MTD, and MTD were compared. Paclitaxel and ixabepilone, at their respective MTDs, produced significant deficits in caudal nerve conduction velocity, caudal amplitude and digital nerve amplitudes, as well as moderate to severe degenerative pathologic changes in dorsal root ganglia and sciatic nerve. In contrast, eribulin mesylate produced no significant deleterious effects on any nerve conduction parameter measured and caused milder, less frequent effects on morphology. Overall, our findings indicate that eribulin mesylate induces less neuropathy in mice than paclitaxel or ixabepilone at equivalent MTD-based doses.

Abstract
Formation of microtubules is a dynamic process that involves polymerization and depolymerization of αβ-tubulin heterodimers. Drugs that enhance or inhibit tubulin polymerization can destroy this dynamic process, arresting cells in the G(2)/M phase of the cell cycle. Although drugs that target tubulin generally demonstrate cytotoxic potency in the subnanomolar range, resistance due to drug efflux is a common phenomenon among the antitubulin agents. We recently reported a class of 4-substituted methoxybenzoyl-aryl-thiazoles (SMART) that exhibited great in vitro potency and broad spectrum cellular cytotoxicity. Evaluation of the in vitro and in vivo anticancer activities of 3 SMART compounds, SMART-H (H), SMART-F (F), and SMART-OH (OH), with varying substituents at the 4-position of aryl ring, demonstrated that they bind potently to the colchicine-binding site in tubulin, inhibit tubulin polymerization, arrest cancer cells in G(2)/M phase of the cell cycle, and induce their apoptosis. The SMART compounds also equipotently inhibit the growth of parental and MDR-overexpressing cells in vitro, indicating that they can overcome multidrug resistance. In vivo antitumor efficacy studies in human prostate (PC-3) and melanoma (A375) cancer xenograft models demonstrated that SMART-H and SMART-F treatments resulted in %T/C values ranging from 4% to 30%. In addition, in vivo SMART-H treatment for 21 days at the higher dose (15 mg/kg) failed to produce any apparent neurotoxicity. These studies provide the first in vivo evidence and proof-of-concept that SMART compounds are similarly efficacious to currently FDA approved antitubulin drugs for cancer treatment, but they can circumvent P-glycoprotein-mediated drug resistance.

Abstract
BACKGROUND ATP7A, ATP7B and CTR1 are metal transporting proteins that control the cellular disposition of copper and platinum drugs, but their expression in dorsal root ganglion (DRG) tissue and their role in platinum-induced neurotoxicity are unknown. To investigate the DRG expression of ATP7A, ATP7B and CTR1, lumbar DRG and reference tissues were collected for real time quantitative PCR, RT-PCR, immunohistochemistry and Western blot analysis from healthy control adult rats or from animals treated with intraperitoneal oxaliplatin (1.85 mg/kg) or drug vehicle twice weekly for 8 weeks. RESULTS In DRG tissue from healthy control animals, ATP7A mRNA was clearly detectable at levels similar to those found in the brain and spinal cord, and intense ATP7A immunoreactivity was localised to the cytoplasm of cell bodies of smaller DRG neurons without staining of satellite cells, nerve fibres or co-localisation with phosphorylated heavy neurofilament subunit (pNF-H). High levels of CTR1 mRNA were detected in all tissues from healthy control animals, and strong CTR1 immunoreactivity was associated with plasma membranes and vesicular cytoplasmic structures of the cell bodies of larger-sized DRG neurons without co-localization with ATP7A. DRG neurons with strong expression of ATP7A or CTR1 had distinct cell body size profiles with minimal overlap between them. Oxaliplatin treatment did not alter the size profile of strongly ATP7A-immunoreactive neurons but significantly reduced the size profile of strongly CTR1-immunoreactive neurons. ATP7B mRNA was barely detectable, and no specific immunoreactivity for ATP7B was found, in DRG tissue from healthy control animals. CONCLUSIONS In conclusion, adult rat DRG tissue exhibits a specific pattern of expression of copper transporters with distinct subsets of peripheral sensory neurons intensely expressing either ATP7A or CTR1, but not both or ATP7B. The neuron subtype-specific and largely non-overlapping distribution of ATP7A and CTR1 within rat DRG tissue may be required to support the potentially differing cuproenzyme requirements of distinct subsets of sensory neurons, and could influence the transport and neurotoxicity of oxaliplatin.

Abstract
Background Cisplatin is primarily used for treatment of ovarian and testicular cancer. Oxaliplatin is the only effective treatment for metastatic colorectal cancer. Both are known to cause dose related, cumulative toxic effects on the peripheral nervous system and thirty to forty percent of cancer patients receiving these agents experience painful peripheral neuropathy. The mechanisms underlying painful platinum-induced neuropathy remain poorly understood. Previous studies have demonstrated important roles for TRPV1, TRPM8, and TRPA1 in inflammation and nerve injury induced pain. Results In this study, using real-time, reverse transcriptase, polymerase chain reaction (RT-PCR), we analyzed the expression of TRPV1, TRPM8, and TRPA1 induced by cisplatin or oxaliplatin in vitro and in vivo. For in vitro studies, cultured E15 rat dorsal root ganglion (DRG) neurons were treated for up to 48 hours with cisplatin or oxaliplatin. For in vivo studies, trigeminal ganglia (TG) were isolated from mice treated with platinum drugs for three weeks. We show that cisplatin and oxaliplatin-treated DRG neurons had significantly increased in TRPV1, TRPA1, and TRPM8 mRNA expression. TG neurons from cisplatin treated mice had significant increases in TRPV1 and TRPA1 mRNA expression while oxaliplatin strongly induced only TRPA1. Furthermore, compared to the cisplatin-treated wild-type mice, cisplatin-treated TRPV1-null mice developed mechanical allodynia but did not exhibit enhancement of noxious heat- evoked pain responses. Immunohistochemistry studies showed that cisplatin-treated mice had no change in the proportion of the TRPV1 immunopositive TG neurons. Conclusion These results indicate that TRPV1 and TRPA1 could contribute to the development of thermal hyperalgesia and mechanical allodynia following cisplatin-induced painful neuropathy but that TRPV1 has a crucial role in cisplatin-induced thermal hyperalgesia in vivo.

Abstract
AIM The current prospective study sought to trace the incidence and severity of oxaliplatin-induced peripheral neuropathy (OXLIPN) and to determine its clinical and electrophysiological pattern. PATIENTS AND METHODS Twenty-five adult patients scheduled to be treated with 12 courses of the oxaliplatin-based regimen, FOLFOX-4, for metastatic colon cancer participated in this study. Patients were clinically and electrophysiologically monitored at baseline and followed-up during chemotherapy. The severity of OXLIPN was summarized by means of a modified Total Neuropathy Score (TNS). RESULTS Evidence of OXLIPN was disclosed in 16 of the 25 patients (64%). The mean TNS values for patients manifesting some grade of OXLIPN were 13.9 +/- 5.8 (range 7-28). All longitudinal comparisons concerning the motor conduction parameters failed to reach significance. By contrast, comparisons of the median changes at baseline and each of the follow-up studies revealed significant decrease in all sensory action potentials examined. CONCLUSION Our results indicate that the majority of patients treated with the FOLFOX-4 regimen would manifest an axonal, predominately sensory peripheral neuropathy, of mild to moderate severity.

Abstract
Indibulin (ZIO-301/D-24851) is an orally applied small molecule with antitumor activity based upon destabilization of microtubule polymerization. The purpose of this phase I study was to determine the maximum tolerated dose (MTD) as well as the dose limiting toxicity (DLT), the pharmacokinetics, safety and tolerability of orally administered indibulin as capsule formulation in patients with advanced solid tumors. Patients received a single dose of indibulin. Seven dose-levels were evaluated: 100 mg, 150 mg, 250 mg, 350 mg and 600 mg once daily (QD), 450 mg and 600 mg twice daily (BID). After a washout period, patients received indibulin at the pre-defined daily dose for 14 days every 3 weeks (multiple dose part). A total of 28 patients entered the study. Indibulin administered as capsules was generally well tolerated. The MTD was not reached. There was a disproportionate increase of the area under the plasma concentration-time curve (AUC) with dose, with declining AUC corrected for dose starting at the 250 mg dose-level. There was no significant difference in AUC of indibulin after multiple dosing (day 1-14) compared to single administration (day-4). Inter-patient variability in AUC (102% CV) was high. A plateau in drug exposure was observed prior to reaching the MTD. Continued dose-escalation was unlikely to yield any increase in exposure of indibulin. The formulation needs optimization to increase the systemic exposure upon oral administration.

Abstract
Background Cisplatin has been in use for 40 years for treatment of germ line and other forms of cancer. Oxaliplatin is approved for treatment of metastatic colorectal cancer. Thirty to forty percent of cancer patients receiving these agents develop pain and sensory loss. Oxaliplatin induces distinctive cold-associated dysesthesias in up to 80% of patients. Results We have established mouse models of cisplatin and oxaliplatin-induced neuropathy using doses similar to those used in patients. Adult male C57BL6J mice were treated with daily intraperitoneal injection for 5 days, followed by 5 days of rest, for two cycles. Total cumulative doses of 23 mg/kg cisplatin and 30 mg/kg oxaliplatin were used. Behavioral evaluations included cold plate, von Frey, radiant heat, tail immersion, grip strength and exploratory behavior at baseline and at weekly intervals for 8 weeks. Following two treatment cycles, mice in the cisplatin and oxaliplatin treatment groups demonstrated significant mechanical allodynia compared to control mice. In addition, the cisplatin group exhibited significant thermal hyperalgesia in hind paws and tail, and the oxaliplatin group developed significant cold hyperalgesia in hind paws. Conclusion We have therefore established a model of platinum drug-induced painful peripheral neuropathy that reflects the differences in early thermal pain responses that are observed in patients treated with either cisplatin or oxaliplatin. This model should be useful in studying the molecular basis for these different pain responses and in designing protective therapeutic strategies.

Abstract
Microtubule-stabilizing and microtubule-destabilizing agents are commonly used as anticancer agents. Although highly effective, success with these agents has been limited due to their relative insolubility, cumbersome synthesis/purification, toxic side effects, and development of multidrug resistance. Hence, the identification of improved agents that circumvent one or more of these problems is warranted. We recently described the rational design of a series of triazole-based compounds as antimitotic agents. Members of this N-substituted 1,2,4-triazole family of compounds exhibit potent tubulin polymerization inhibition and broad spectrum cellular cytotoxicity. Here, we extensively characterize the in vitro and in vivo effects of our lead compound from the series 1-methyl-5-(3-(3,4,5-trimethoxyphenyl)-4H-1,2,4-triazole-4-yl)-1H-indole, designated T115. We show that T115 competes with colchicine for its binding pocket in tubulin, produces robust inhibition of tubulin polymerization, and disrupts the microtubule network system inside the cells. In addition, T115 arrests human cancer cells in the G(2)-M phase of cell cycling, a hallmark of microtubule destabilizing drugs. T115 also inhibits cell viability of several cancer cell lines, including multidrug-resistant cell lines, in the low nanomolar range. No cytotoxicity was observed by T115 against normal human skin fibroblasts cell lines, and acute toxicity studies in normal nontumor-bearing mice indicated that T115 is well-tolerated in vivo (maximum total tolerated dose, 400 mg/kg). In a mouse xenograft model using human colorectal (HT-29) and prostate (PC3) cancer cells, T115 significantly inhibited tumor growth when administered i.p. Taken together, our results suggest that T115 is a potential drug candidate for cancer chemotherapy.

Abstract
Chemotherapy-induced peripheral neuropathy (CIPN) is still a common and disabling side effect of many chemotherapy agents in use today. Unfortunately, neither prophylactic strategies nor symptomatic treatments have proven useful yet. This review will discuss the diagnosis and evaluation of neuropathy in cancer patients, as well as reviewing the various prophylactic and symptomatic treatments that have been proposed or tried. However, sufficient evidence is lacking to recommend any of these treatments to patients suffering with CIPN. Therefore, the best approach is to treat symptomatically, and to start with broad-spectrum analgesic medications such as non-steroidal anti-inflammatory drugs (NSAIDs). If NSAIDs fail, a reasonable second-line agent in properly selected patients may be an opioid. Unfortunately, even when effective in other types of neuropathic pain, anti-depressants and anticonvulsants have not yet proven effective for treating the symptoms of CIPN.

Abstract
PURPOSE To determine the recommended phase II dose of combination ixabepilone plus carboplatin based on the maximum tolerated dose, pharmacokinetics, optimum schedule, and safety. EXPERIMENTAL DESIGN Patients with advanced solid malignancies were treated with escalating doses of carboplatin plus ixabepilone administered on day 1 (schedule A) or days 1 and 8 (schedule B) of a 21-day cycle. Blood was sampled during cycle 1 for pharmacokinetic analysis of ixabepilone (both schedules) and carboplatin (schedule B). RESULTS Fifty-two patients were treated with ixabepilone doses ranging from 30 to 50 mg/m2 per 21-day cycle plus carboplatin area under curve (AUC) 5 or 6 (Calvert formula). On schedule A (ixabepilone 40 mg/m2 over 1 hour plus carboplatin AUC 6), 2 of 2 patients experienced dose-limiting toxicity (DLT). On schedule B (ixabepilone 25 mg/m2 over 1 hour on days 1 and 8 plus carboplatin AUC 6), 3 of 3 patients experienced DLT. DLT was myelosuppression; however, cumulative sensory neuropathy limited extended dosing on schedule A. Ixabepilone and carboplatin pharmacokinetics were similar to those using either drug as monotherapy, indicating an absence of pharmacokinetic drug interactions. Based on DLTs and tolerability with repeated dosing, the recommended doses were 30 mg/m2 ixabepilone (1-hour infusion) d1 q3w plus carboplatin AUC 6 (schedule A) and 20 mg/m2 ixabepilone (1 hour infusion) d1, d8 q3w plus carboplatin AUC 6 (schedule B). CONCLUSIONS Data from the present study show the feasibility and tolerability of combination ixabepilone plus carboplatin, with ixabepilone administered on day 1 or on days 1 and 8 on a 21-day cycle.

Abstract
Chemotherapy-induced peripheral neuropathy (CIPN) is a major dose limiting side effect of many commonly used chemotherapeutic agents, including platinum drugs, taxanes, epothilones and vinca alkaloids, and also newer agents such as bortezomib and lenolidamide. Symptom control studies have been conducted looking at ways to prevent or alleviate established CIPN. This manuscript provides a review of studies directed at both of these areas. New evidence strongly suggests that intravenous calcium and magnesium therapy can attenuate the development of oxaliplatin-induced CIPN, without reducing treatment response. Accumulating data suggest that vitamin E may also attenuate the development of CIPN, but more data regarding its efficacy and safety should be obtained prior to its general use in patients. Other agents that look promising in preliminary studies, but need substantiation, include glutamine, glutathione, N-acetylcysteine, oxcarbazepine, and xaliproden. Effective treatment of established CIPN, however, has yet to be found. Lastly, paclitaxel causes a unique acute pain syndrome which has been hypothesised to be caused by neurologic injury. No drugs, to date, have been proven to prevent this toxicity.

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
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
Indibulin is a synthetic small molecule which antitumor activity is based upon destabilization of microtubules. The primary study objectives were to determine the impact of fasted and fed condition on pharmacokinetic parameters, as well as the maximum tolerated dose of the oral drinking solution of indibulin administered once daily for 14 days every 3 weeks in patients with solid tumors. In the pilot food effect part, patients received a single dose of 20 mg indibulin on day-8 and -4, fasted or fed, in a randomized crossover design. In the dose-escalation part, patients received a single dose of indibulin on day-4. Three dose levels were evaluated: 20, 40 and 80 mg. After a washout period, patients received indibulin once daily for 14 days every 3 weeks (multiple dose part). Blood samples were collected in the pilot food effect- and in the dose escalation study. A total of 14 patients entered, of which 6 completed the food effect study. The ratio of indibulin (fed/fasted) in the food effect study for AUC(0-72) was estimated as 1.24 (P=0.082, 95%CI 0.96-1.41) and C(max) ratio was 0.89 (P=0.54, 95%CI 0.55-1.44). Interpatient variability was high. Higher peak plasma concentrations were reached under fasting conditions which was undesired regarding tolerability. Therefore the dose escalation study was continued under fed conditions. Dose limiting toxicities, nausea and vomiting, appeared to be related to the increased volume of the solvent lactic acid. This study is continued, evaluating indibulin administered as capsules on the recommended dose level of 60 mg daily for 14 days.

Abstract
AIMS Bortezomib (Velcade), a novel proteasome inhibitor, has shown promise in the treatment of malignancies, including multiple myeloma and non-Hodgkin's lymphoma. Several studies have identified neuropathy as a potentially dose-limiting side effect of treatment with bortezomib. We report the clinical and electrodiagnostic data from four patients who developed signs and symptoms of peripheral neuropathy from treatment with bortezomib. MATERIALS AND METHODS Patients were included if they were enrolled in active phase 2 trials of bortezomib for non-Hodgkin's lymphoma or prostate cancer, developed signs and symptoms of peripheral neuropathy, and were referred for electrodiagnostic evaluation. RESULTS Four patients, including two with non-Hodgkin's lymphoma and two with prostate cancer, underwent electrodiagnostic testing. Electrodiagnostic evaluation showed pre-existing peripheral nervous system disorders in three out of four patients. Multiple peripheral nervous system disorders were present in two out of four patients. CONCLUSIONS Bortezomib can cause a predominately sensory axonal polyneuropathy. Pre-existing peripheral nervous system disorders, such as neuropathy and radiculopathy, are common in patients with cancer, and may pre-dispose to the development of symptomatic neuronal toxicity when treated with bortezomib. Baseline electrodiagnostic evaluation may identify patients with pre-existing peripheral nervous system disorders at risk for additive neuronal toxicity from neurotoxic chemotherapeutic agents.

Abstract
AIM A randomized, open label with blind assessment, controlled trial was performed to assess efficacy and adverse-event profile of vitamin E, given as supplementation for prophylaxis against cisplatin-induced peripheral neuropathy (CIPN). PATIENTS AND METHODS A total of 30 patients scheduled to receive six courses of cumulative cisplatin-based regimens were randomly allocated to treatment and control groups and were then studied by means of neurological examination and electrophysiological study. Patients assigned to group I (n=14) orally received vitamin E at a daily dose of 600 mg/day during chemotherapy and 3 months after its cessation were compared to patients of group II (n=16), who received no vitamin E supplementation and served as controls. The severity of neurotoxicity was summarized by means of a modified Peripheral Neuropathy (PNP) score. RESULTS The incidence of neurotoxicity differed significantly between groups, occurring in 3/14 (21.4%) of patients assigned to the vitamin E supplementation group and in 11/16 (68.5%) of controls (p=0.026). The relative risk (RR) of developing neurotoxicity was significantly higher in case of controls, RR=2.51, 95% C.I.=1.16-5.47. Mean PNP scores were 4.99+/-1.33 for patients of group I and 10.47+/-10.62 for controls, (p=0.023). None of the adverse events or deaths occurred, were judged as likely to be related to the vitamin E supplementation. CONCLUSION Vitamin E effectively and safely protects patients with cancer from occurrence of cisplatin neurotoxicity.

Abstract
The current study aimed to assess the viability of sympathetic sudomotor fibers in cancer patients treated with cisplatin or paclitaxel-based chemotherapy and to ascertain whether this method could contribute to the diagnostic sensitivity of conventional techniques. Sympathetic skin response (SSR) from the hand and sole of 23 cancer patients (nine females and 14 males, mean age 62.4 +/- 10.5 years) was recorded unilaterally before and after chemotherapy with six courses of cumulative cisplatin or paclitaxel containing regimens. Clinical and electrophysiological data were also collected and correlated with the SSR results. Twenty-three healthy subjects served as controls. SSR abnormalities were only present in patients with evidence of peripheral neuropathy assessed by conventional nerve conduction techniques. Three patients had absent SSR in the upper limb whilst six patients had absent SSR both in the upper and lower limbs. In the upper limb, the mean SSR latency was not significantly altered through time (P = 0.086). In the lower limb the mean delay from baseline to follow-up was significantly changed (P = 0.029). In patients, the mean SSR latency was significantly prolonged compared with controls in both upper limb (P = 0.001) and lower limb (P = 0.000). SSR abnormalities were strongly related to sensory conduction abnormalities as detected by conventional techniques (r = 0.39, P = 0.004). Our results showed that SSR does not seem to add to the diagnostic sensitivity of conventional techniques in chemotherapy-induced neuropathy. However, its role in the disclosure of small fibers neuropathy abnormalities is worth considering. Further studies are warranted to address this important issue.

Abstract
Combined anticancer therapy using platinum compounds and antitubulins has increased the risk of neurotoxicity. However, the combination of low-dose cisplatin (CDDP) with toxic doses of paclitaxel significantly reduces cellular death in a human neuroblastoma SH-SY5Y cell line. To analyze the mechanisms of this protection, we evaluated various signaling molecules possibly involved in apoptosis and some relevant cell cycle regulatory proteins. CDDP does not interfere with the tubulin-stabilizing action of paclitaxel. The evaluation of molecular pathways involved in apoptosis indicates that the Bcl-2 but not the caspases may be involved in the CDDP protection of paclitaxel-induced apoptosis. The increase in p53 protein and its nuclear accumulation suggests a possible involvement of p53 in CDDP protection. The use of the chemical inhibitor of p53, pifithrin alpha, excluded this possibility. The study of cyclins and the flow cytometric analysis (fluorescence-activated cell sorting) suggest that CDDP exerts a protective action by blocking cells early in the cell cycle. The determination of the mitotic index indicates that CDDP prevents cells from reaching the mitosis. We concluded that low doses of CDDP are protective against toxic doses of paclitaxel and that the possible mechanism of this protection is that the CDDP prevents human neuroblastoma SH-SY5Y cells from achieving mitosis.

Abstract
OBJECTIVE The current study intended to determine the incidence, severity and reversibility of paclitaxel plus carboplatin (CP)-induced peripheral neuropathy (CPPN) and to describe its clinical and electrophysiological features. PATIENTS AND METHODS We prospectively studied 21 adult patients scheduled to be treated with 6 courses of cumulative carboplatin plus paclitaxel (CP) regimens for a non-myeloid malignancy. They were followed-up by neurological examination and electrophysiological study during chemotherapy and 3 months after its discontinuation. The severity of neurotoxicity was assessed by means of a modified peripheral neuropathy (PNP) score. RESULTS Evidence of CPPN was recorded in 14 of the 21 patients (66.6 %). The sensory symptoms were present in the lower limbs first and then involved the upper limbs. No statistical significance, concerning the changes from baseline to subsequent mean scores in all motor conduction parameters examined,was revealed. By contrast, comparisons of the mean changes at baseline and each of the follow-up studies showed significant decrease in all sensory action potentials examined. The mean PNP scores for patients that manifested some grade of neurotoxicity were 17.9 +/- 9.8. The followup data 3 months after the discontinuation of chemotherapy showed that the CP-induced neuropathy was at least partially reversed. CONCLUSIONS CP-induced neuropathy was symmetrical, distal and predominantly sensory in character, though minor to moderate motor signs were only evident in severely affected patients. Reversibility of CP-induced neuropathy was partially observed after the suspension of chemotherapy.

Abstract
HER2 is a validated therapeutic target for cancer. There are no natural ligands, but monoclonal antibodies and peptides that bind HER2 act as artificial ligands, selectively affecting HER2-overexpressing tumors. One reported mechanism for this effect is receptor downregulation, but the expected correlation of ligand-dependent HER2 internalization and tumor inhibition remain poorly characterized. Moreover, HER2 ligands have limited therapeutic efficacy and often they require adjuvant treatment with the chemotherapeutic Taxol. Here, we generated a series of HER2 ligands (Anti-HER2/neu peptide ligands, AHNPmonovalent and AHNPbivalent) with different valency and correlated their internalization-promoting ability to biological potency. Since AHNPbivalent (but not AHNPmonovalent) induces rapid receptor internalization, we exploited this feature to deliver cytotoxic conjugates coupling AHNPbivalent and Taxol (Taxol . AHNPbivalent). The prodrug conjugate releases Taxol after receptor-mediated internalization, and cytotoxicity can be used as a marker of internalization. Taxol . AHNPbivalent is significantly more cytotoxic than free Taxol + free AHNPbivalent. Hence, the Taxol x AHNP(bivalent) prodrug binds to HER2, induces receptor internalization and downregulation, and the subsequent release of free Taxol inside the targeted cell results in synergistic toxicity, The effect is selective towards HER2- expressing cells. This work links HER2 receptor internalization and growth arrest, and the chemical conjugation strategy may yield improved and HER2 selective therapeutics.

Abstract
Chemotherapy-induced peripheral neurotoxicity (CIPN) is a major clinical problem because it represents the dose-limiting side effects of a significant number of antineoplastic drugs. The incidence of CIPN varies depending on the drugs and schedules used, and this can be quite high, particularly when neurophysiological methods are used to make a diagnosis. However, even when CIPN is not a dose-limiting side effect, its onset may severely affect the quality of life of cancer patients and cause chronic discomfort. In this review the features of CIPN due to the administration of the most widely used drugs, such as platinum drugs, taxanes and vinca alkaloids, and of two old drugs with new clinical applications, suramin and thalidomide, will be discussed. Moreover, the earliest data regarding the neurotoxicity of some new classes of very promising antineoplastic agents, such as epothilones and proteasome inhibitors, will be discussed. Finally, the data available on neuroprotectants, evaluated in the attempt to prevent CIPN, will be summarised.

Abstract
Chemotherapy remains the preferred choice of treatment for prostate cancer but modest drug response and significant toxicity by conventional methods of administration limit their efficacy. In our study, we determined the efficacy of paclitaxel (Tx)-loaded biodegradable nanoparticles (NPs) on tumor inhibition. We hypothesized that NPs following conjugation to transferrin (Tf) ligand (NPs-Tf) would enhance the therapeutic efficacy of the encapsulated drug. The antiproliferative activity of NPs was determined in human prostate cancer cell line (PC3) and their effect on tumor inhibition in a murine model of prostate cancer. NPs (approximately 220 nm in diameter, 5.4% w/w drug loading) under in vitro conditions exhibited sustained release of the encapsulated drug (60% release in 60 days). The IC50 (concentration of drug for 50% inhibition of cell growth) of the drug with Tf-conjugated NPs (Tx-NPs-Tf) was about 5-fold lower than that with unconjugated NPs (Tx-NPs) or drug in solution. Animals that received a single-dose intratumoral injection of Tx-NPs-Tf (Tx dose= 4 mg/kg) demonstrated complete tumor regression and greater survival rate than those that received either Tx-NPs or Tx-Cremophor EL formulation. In conclusion, sustained release NPs demonstrated greater antitumor activity following their conjugation to Tf ligand.

Abstract
Using doses close to those used clinically, we have developed an animal model of vincristine-induced nociceptive sensory neuropathy after repeated intravenous injection in male Sprague-Dawley rats. In order to validate the model, three different doses (50, 100 and 150 microg/kg) of vincristine were injected every 2nd day until five injections had been given. The sensory behavioural assessment revealed mechanical hyperalgesia and allodynia associated with cold thermal hyperalgesia and allodynia. With regard to electrophysiological evaluation, we observed a decrease in the nerve conduction velocity in the highest dose group. Morphological studies revealed few degenerated fibers in the sciatic nerve and many degenerated myelinated axons in the fine nerve fibers of the subcutaneous paw tissue. Finally, to develop an animal model, we chose the 150 microg/kg dose because of the good general clinical status of the rats without motor function changes associated with severe sensation disorders like hyperalgesia and allodynia. This model of vincristine-induced painful neuropathy will be used to explore physiopathological mechanisms implied in the genesis of neuropathic pain and also to test new analgesic and neuroprotective drugs.

Abstract
Venlafaxine, a new antidepressant with fewer side effects, could be of interest to reduce neuropathic pain following antineoplasic drug treatment. In the present study, we demonstrated that venlafaxine inhibits hyperalgesia in a new rat model of neuropathy induced by the antineoplasic drug vincristine, and exerts its effect preferentially via supraspinal and spinal mechanisms.

Abstract
trans-Resveratrol (3,4',5-trihydroxystilbene) is able to significantly reduce paclitaxel-induced apoptosis in the human neuroblastoma (HN) SH-SY5Y cell line, acting on several cellular signaling pathways that are involved in paclitaxel-induced apoptosis. trans-Resveratrol reverses phosphorylation of Bcl-2 induced by paclitaxel and concomitantly blocks Raf-1 phosphorylation, also observed after paclitaxel exposure, thus suggesting that Bcl-2 inactivation may be dependent on the activation of the Raf/Ras cascade. trans-Resveratrol also reverses the sustained phosphorylation of JNK/SAPK, which specifically occurs after paclitaxel exposure.Overall, our observations demonstrate that (a) the toxic action of paclitaxel on neuronal-like cells is not only related to the effect of the drug on tubulin, but also to its capacity to activate several intracellular pathways leading to inactivation of Bcl-2, thus causing cells to die by apoptosis, (b) trans-resveratrol significantly reduces paclitaxel-induced apoptosis by modulating the cellular signaling pathways which commit the cell to apoptosis.
