Abstract
PURPOSE OF REVIEW This review aims to discuss pathophysiology, diagnosis, clinical presentation, and treatment of chemotherapy-induced peripheral neuropathy. Agent-specific presentation and pathophysiology is also being discussed. RECENT FINDINGS As new systemic oncological treatments continue to be developed, the number of cancer survivors continues to grow. Survivors are living longer with the long-term side effects of oncological treatments. We reviewed the pathophysiology of agent-specific chemotherapy-induced peripheral neuropathy and the updates in its treatment and preventative tools. Chemotherapy-induced peripheral neuropathy is a debilitating long-term side effect that often impairs cancer survivors' function and quality of life. The increasing life expectancy of cancer survivors has resulted in increased prevalence of this condition. Understanding its intricacies can provide physicians with better treatment tools and research opportunities to develop or identify new therapeutic agents.

Potential Mediators of Oxaliplatin-Induced Peripheral Neuropathy From Adjuvant Therapy in Stage III Colon Cancer: Findings From CALGB (Alliance)/SWOG 80702. J Clin Oncol 2023; 41:1079-1091. [PMID: 36367997 PMCID: PMC9928634 DOI: 10.1200/jco.22.01637] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2022] [Revised: 08/29/2022] [Accepted: 10/06/2022] [Indexed: 11/13/2022] Open
Abstract
PURPOSE We sought to evaluate the independent and interactive associations of planned treatment duration, celecoxib use, physical activity, body mass index (BMI), diabetes mellitus, and vitamin B6 with oxaliplatin-induced peripheral neuropathy (OIPN) among patients with stage III colon cancer enrolled in a clinical trial. METHODS We conducted a prospective, observational study of 2,450 patients with stage III colon cancer enrolled in the CALGB/SWOG 80702 trial, randomly assigned to 6 versus 12 cycles of adjuvant fluorouracil, leucovorin, and oxaliplatin chemotherapy with or without 3 years of celecoxib. OIPN was reported using the Common Terminology Criteria for Adverse Events (CTCAE) during and following completion of chemotherapy and the FACT/GOG-NTX-13 15-17 months after random assignment. Multivariate analyses were adjusted for baseline sociodemographic and clinical factors. RESULTS Patients assigned to 12 treatment cycles, relative to 6, were significantly more likely to experience higher-grade CTCAE- and FACT/GOG-NTX-13-reported neuropathy and longer times to resolution, while neither celecoxib nor vitamin B6 intake attenuated OIPN. Exercising ≥ 9 MET-hours per week after treatment relative to < 9 was associated with improvements in FACT/GOG-NTX-13-reported OIPN (adjusted difference in means, 1.47; 95% CI, 0.49 to 2.45; P = .003). Compared with patients with baseline BMIs < 25, those with BMIs ≥ 25 were at significantly greater risk of developing higher-grade CTCAE-reported OIPN during (adjusted odds ratio, 1.18; 95% CI, 1.00 to 1.40; P = .05) and following completion (adjusted odds ratio, 1.23; 95% CI, 1.01 to 1.50; P = .04) of oxaliplatin treatment. Patients with diabetes were significantly more likely to experience worse FACT/GOG-NTX-13-reported neuropathy relative to those without (adjusted difference in means, -2.0; 95% CI, -3.3 to -0.73; P = .002). There were no significant interactions between oxaliplatin treatment duration and any of these potentially modifiable exposures. CONCLUSION Lower physical activity, higher BMI, diabetes, and longer planned treatment duration, but not celecoxib use or vitamin B6 intake, may be associated with significantly increased OIPN severity.

Abstract
Neuropathic pain is defined as pain caused by a lesion or disease of the somatosensory nervous system and affects 7-10% of the worldwide population. Neuropathic pain can be induced by the use of drugs, including taxanes, thus triggering chemotherapy-induced neuropathic pain or as consequence of metabolic disorders such as diabetes. Neuropathic pain is most often a chronic condition, and can be associated with anxiety and depression; thus, it negatively impacts quality of life. Several pharmacologic approaches exist; however, they can lead numerous adverse effects. From this perspective, the use of nutraceuticals and diet supplements can be helpful in relieve neuropathic pain and related symptoms. In this review, we discuss how diet can radically affect peripheral neuropathy, and we focus on the potential approaches to ameliorate this condition, such as the use of numerous nutritional supplements or probiotics.

Abstract
Purpose The aim of our study was to analyze the use of complementary and alternative medicine (CAM) supplements, identify possible predictors, and analyze and compile potential interactions of CAM supplements with conventional cancer therapy. Methods We included outpatient cancer patients treated at a German university hospital in March or April 2020. Information was obtained from questionnaires and patient records. CAM–drug interactions were identified based on literature research for each active ingredient of the supplements consumed by the patients. Results 37.4% of a total of 115 patients consumed CAM supplements. Potential interactions with conventional cancer treatment were identified in 51.2% of these patients. All types of CAM supplements were revealed to be a potential source for interactions: vitamins, minerals, food and plant extracts, and other processed CAM substances. Younger age (< 62 years) (p = 0.020, φc = 0.229) and duration of individual cancer history of more than 1 year (p = 0.006, φc = 0.264) were associated with increased likelihood of CAM supplement use. A wide range of different CAM supplement interactions were reviewed: effects of antioxidants, cytochrome (CYP) interactions, and specific agonistic or antagonistic effects with cancer treatment. Conclusion The interaction risks of conventional cancer therapy with over-the-counter CAM supplements seem to be underestimated. Supplements without medical indication, as well as overdoses, should be avoided, especially in cancer patients. To increase patient safety, physicians should address the risks of interactions in physician–patient communication, document the use of CAM supplements in patient records, and check for interactions.

Anticancer Agents Med Chem 2020; 19:1775-1783. [PMID: 30914033 DOI: 10.2174/1871520619666190325150624] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2018] [Revised: 03/08/2019] [Accepted: 03/19/2019] [Indexed: 11/22/2022]
Abstract
BACKGROUND Cisplatin (CisPt) has a well-recognized anticancer activity by interacting with DNA and inducing programmed cell death. However, theoretical studies performed on the molecular level suggest that such nonspecific interactions can also take place with many competitive compounds, such as vitamins containing aromatic rings with lone-pair orbitals. OBJECTIVE This work is a theoretical study on the initial Pt-N7(N1) bond formation with vitamins from B group and their comparison with values characterizing native purines. METHODS Geometries of studied structures were optimized with an aid of Gaussian 09 using the B3LYP functional with the 6-31G** basis set. Atomic orbitals of platinum were represented by the lanl2dz basis. Solvation free energies were evaluated by a self-consistent reaction field (SCRF) approach. A dielectric constant of 78 for water was used in the PCM continuum model computations along with radii Bondii. RESULTS The affinities of mono-aqua cis~[Pt(NH3)2Cl(H2O)]+ and di-aqua cis~ [Pt(NH3)2(H2O)2]2+ derivatives of Cisplatinum toward compounds belonging to the group of eight B vitamins were studied and compared to interactions with canonical purines. All the values of ΔGr unambiguously indicate that reactions with cisPt-diaqua are more preferable, but the comparison of ΔGr values obtained for compounds from vitamin B group and the ones characterizing complexes created by Guanine molecules indicates higher affinity of cisPt monomers toward purines. CONCLUSION Based on the observations, the regular intake of vitamin-rich beetroot or carrot juices is strongly discouraged during anticancer therapy using CisPt drug. To confirm the results of the performed computational study, detailed clinical trials should be performed.

Abstract
Chemotherapy-induced peripheral neuropathy (CIPN) is an adverse effect of chemotherapy that is frequently experienced by patients receiving treatment for cancer. CIPN is caused by many of the most commonly used chemotherapeutic agents, including taxanes, vinca alkaloids, and bortezomib. Pain and sensory abnormalities may persist for months, or even years after the cessation of chemotherapy. The management of CIPN is a significant challenge, as it is not possible to predict which patients will develop symptoms, the timing for the appearance of symptoms can develop anytime during the chemotherapy course, there are no early indications that warrant a reduction in the dosage to halt CIPN progression, and there are no drugs approved to prevent or alleviate CIPN. This review focuses on the etiology of CIPN and will highlight the various approaches developed for prevention and treatment. The goal is to guide studies to identify, test, and standardize approaches for managing CIPN.

Abstract
Background and Aims: In cancer patients, a common complication during chemotherapy is chemotherapy-induced peripheral neuropathy (CIPN). For this reason, we decided to conduct a phase II prospective study on 33 patients with multiple myeloma at first diagnosis, to evaluate whether a nutraceutical compound given for 6 months during bortezomib (BTZ) treatment succeeded in preventing the onset of neurotoxicity. Methods: Neurological evaluation, electroneurography, and functional and quality of life (QoL) scales were performed at baseline and after 6 months. We administered a tablet containing docosahexaenoic acid 400 mg, α-lipoic acid 600 mg, vitamin C 60 mg, and vitamin E 10 mg bid for 6 months. Results: Concerning the 25 patients who completed the study, at 6-month follow-up, 10 patients had no neurotoxicity (NCI-CTCAE [National Cancer Institute-Common Terminology Criteria for Adverse Events] = 0), while 13 progressed to NCI-CTCAE grade 1, 1 had NCI-CTCAE grade 1 with pain, and 1 experienced a NCI-CTCAE grade 2. Painful symptoms were reported only in 2 patients, and we observed stability on functional and QoL scales in all patients. None of the 25 patients stopped chemotherapy due to neurotoxicity. Conclusions: Our data seem to indicate that the co-administration of a neuroprotective agent during BTZ treatment can prevent the appearance/worsening of symptoms related to CIPN, avoiding the interruption of BTZ and maintaining valuable functional autonomy to allow normal daily activities. We believe that prevention remains the mainstay to preserve QoL in this particular patient population, and that future studies with a larger patient population are needed.

Abstract
Radiotherapy (RT) causes morbidity and long-term side effects. A challenge in RT is to maximize cancer cells killing while minimizing damage to normal tissue. The ideal radio-protector selectively improves survival and limits damage to normal tissues while reducing survival of cancer cells. Muscle-derived dipeptide, L-carnosine (CAR) is a potent antioxidant, with radio-protective, but also anticancer properties, affecting the cell cycle of cancer cells. We tested CAR effects in lung cancer cells, differentiated and undifferentiated normal cells. We hypothesized that CAR antioxidant properties will confer protection to the two normal cell lines against RT, while preventing lung cancer cell proliferation, and that CAR may act as a radiosensitizer of lung cancer cells due to its effects on cell-cycle progression of cancer cells. Under the experimental conditions reported here, we found that CAR increased radio-sensitivity of lung (A549) cancer cells by increasing the percentage of cells in G2/M (radiosensitive) phase of cell cycle, it negatively affected their bioenergetics, therefore reduced their viability, and DNA-double strand break repair capacity. CAR had either no effect or reduced RT-induced damage in normal cells, depending on the cell type. CAR is a versatile natural occurring compound, that could improve RT-induced lung cancer cells killing, while reducing the damage to normal differentiated and undifferentiated cells.

Abstract
Most of the population does not seek professional advice before taking vitamin products and their indiscriminate use can lead to serious health risks. This study aims to demonstrate, through bibliographic survey, the risks of indiscriminate use of vitamin products related to hypervitaminosis and major drug interactions which the multivitamins are involved. A bibliographic survey was conducted in the databases LILACS, SciELO, PubMed, Medline, Micromedex, Drugs.com and textbooks on the subject. Vitamins are commonly described as harmless products by the majority of the population, but these trace elements can interact with other substances, causing mild disconforts or treatment failure for the patient, severe consequences to the body and can lead to death. To avoid the indiscriminate use of vitamin products, it is necessary that health professionals know and use specific laboratory tests for the determination of vitamins in the body, preventing these products from being unnecesarily prescribed. Also, the knowledge about what the possible effects of the indiscriminate use of vitamin supplements can lead to the rational use of these products.

Abstract
Cisplatin (cisPt) is one of the strongest anticancer agents with proven clinical activity against a wide range of solid tumors. Its mode of action has been linked to its ability to crosslink with the canonical purine bases, primarily with guanine. Theoretical studies performed at the molecular level suggest that such nonspecific interactions can also take place with many competitive compounds, such as vitamins of the B group, containing aromatic rings with lone-pair orbitals. This might be an indicator of reduction of the anticancer therapeutic effects of the Cisplatin drug in the presence of vitamins of the B group inside the cell nucleus. That is why it seems to be important to connect CisPt with nanostructures and in this way prevent the drug from combining with the B vitamins. As a proposal for a new nanodrug, an attempt was made to implement Cispaltin (CisPt) ligand on functionalized C60 fullerenes and on a cube rhombellane homeomorphic surface. The symmetry of the analyzed nanostructures is an important factor determining the mutual affinity of the tested ligand and nanocarriers. The behavior of Cisplatin with respect to rhombellane homeomorphs and functionalized fullerenes C60, in terms of their (interacting) energy, geometry and topology was studied and a detailed analysis of structural properties after docking showed many interesting features.

Abstract
Background and Aims: Peripheral neuropathy is a common complication of chemotherapy that can induce marked disability that negatively affects the quality of life in patients with multiple myeloma (MM). The aim of this study was to prevent the onset or the worsening of peripheral neuropathy in MM patients treated with bortezomib (BTZ), using a new nutritional neuroprotective compound. We report preliminary results of 18 out of 33 patients who completed the study. Methods: We administered a tablet of Neuronorm to patients, containing docosahexaenoic acid 400 mg, α-lipoic acid 600 mg, vitamin C 60 mg, and vitamin E 10 mg bid for the whole follow-up period. Neurological visit assessment, electroneurography, and evaluation scales were performed at baseline and after 6 months. Results: At 6 months, 8 patients had no chemotherapy-induced peripheral neuropathy, while 10 patients experienced chemotherapy-induced peripheral neuropathy of grade 1 according to the Common Terminology Criteria for Adverse Events, one of them with pain. Seventeen patients did not report painful symptoms; no limitation of functional autonomy and stability in quality of life domains explored was observed. Conclusions: Our results seem to indicate that early introduction of a neuroprotective agent in our patients with MM treated with BTZ could prevent the onset or the worsening of neuropathic pain, avoiding the interruption of the therapy with BTZ, and maintaining a good functional autonomy to allow normal daily activities. Despite the limitations due to the fact that this is a preliminary study, in a small population, with short follow-up, our data seem to indicate that the nutraceutical may have some potential to be considered for a future trial.

Antioxidants as precision weapons in war against cancer chemotherapy induced toxicity - Exploring the armoury of obscurity. Saudi Pharm J 2017; 26:177-190.

Abstract
Cancer is the leading cause of mortality worldwide, accounting for almost 13% of deaths in the world. Among the conventional cancer treatments, chemotherapy is most frequently carried out to treat malignant cancer rather than localised lesions which is amenable to surgery and radiotherapy. However, anticancer drugs are associated with a plethora of side effects. Each drug, within every class, has its own set of adverse reactions which may cause patient incompliance and deterioration of the quality of life. One of the major causes of adverse reactions, especially for drugs targeting DNA, is the excessive production of reactive oxygen species (ROS) and subsequent build up of oxidative stress. To curb these undesired side effects, several dietary supplements have been tested, amongst which antioxidants have gained increasing popularity as adjuvant in chemotherapy. However, many oncologists discourage the use of antioxidant rich food supplements because these may interfere with the modalities which kill cancer by generating free radicals. In the present review, all studies reporting concomitant use of several antioxidants with chemotherapy are indiscriminately included and discussed impartially. The effect of supplementation of thirteen different antioxidants and their analogues as a single agent or in combination with chemotherapy has been compiled in this article. The present review encompasses a total of 174 peer-reviewed original articles from 1967 till date comprising 93 clinical trials with a cumulative number of 18,208 patients, 56 animal studies and 35 in vitro studies. Our comprehensive data suggests that antioxidant has superior potential of ameliorating chemotherapeutic induced toxicity. Antioxidant supplementation during chemotherapy also promises higher therapeutic efficiency and increased survival times in patients.

Abstract
PURPOSE OF REVIEW The purpose of this mini review is to evaluate the literature on B vitamins and chemotherapy-induced peripheral neuropathy. RECENT FINDINGS One hundred and five journal articles were evaluated and nine manuscripts were included. There was one in vitro, one was an animal and seven were human studies. The in vitro study was a safety study on vitamin B6 and oxaliplatin which was not directly related to CIPN. The animal study evaluated vitamin B3 on paclitaxel administration with positive results. The human studies varied using a vitamin B complex, vitamin B12 only and vitamin B6. Chemotherapy-induced peripheral neuropathy (CIPN) continues to plague patients and the medical fraternity. Currently, there are still no conclusive protective or treatment options. B vitamins have been found to play a role in CIPN prevention, but further studies are required to ascertain possible protection and treatment options.

Abstract
Objective. To provide a comprehensive review of the chemotherapy induced dermatological toxi-city, palmar-plantar erythrodysesthesia (PPE), including clinical presentation, drugs implication in causing the reaction, and approaches for management. Data sources. A search of MEDLINE (1966-2002), IDIS (1985- 2002) and CANCERLIT (1993-2002) databases was conducted using the terms (and variations of the terms) palmar-plantar erythrodysesthesia, hand-foot syndrome, and acral erythema. Bibliographies from selected articles were also reviewed for appropriate references. Data extraction. The retrieved literature was reviewed to include all articles pertaining to the incidence, clinical presentation, mechanism, pathology, diagnosis, treatment and prevention of PPE. Data synthesis. PPE is a distinctive, localized cutaneous reaction to certain antineoplastic agents. A number of drugs have been implicated, including most commonly cytarabine, fluorouracil, doxorubicin, and capecitabine. There appears to be an association with administration schedules that lead to elevated peak plasma concentrations, such as in high-dose therapy, or after prolonged periods of constant exposure, as with continuous infusions, regular oral dosing, or liposomal formulations. The extent and severity of the reaction, time of onset, and duration are variable. Symptoms can occur to both hands and feet, and include dysesthesia, paresthesia, erythema, swelling, pain, blistering, ulceration, and desquamination. Cessation of the offending agent appears to be the most important step in the management of PPE. Dose modification may be necessary for subsequent cycles. As the course of PPE is self-limiting, treatment is commonly supportive and based on the type and severity of symptoms encountered. This can include analgesia, emollient or soothing creams, wound care, and cold compresses. Administration of corticosteroids has produced mixed results. Pyridoxine shows promise as both a treatment and preventative strategy, although confirmation in prospective clinical trials is needed. Advice should be provided to patients to ensure prompt recognition of toxicity and plans for prevention and amelioration of symptoms provided.

Abstract
OBJECTIVE Neurological complications such as chemotherapy-induced peripheral neuropathy (CIPN) and neuropathic pain are frequent side effects of neurotoxic chemotherapy agents. An increasing survival rate and frequent administration of adjuvant chemotherapy treatments involving neurotoxic agents makes it imperative that accurate diagnosis, prevention, and treatment of these neurological complications be implemented. METHODS A consideration was undertaken of the current options regarding protective and treatment interventions for patients undergoing chemotherapy with neurotoxic chemotherapy agent or experience with CIPN. Current knowledge on the mechanism of action has also been identified. The following databases PubMed, the Cochrane Library, Science Direct, Scopus, EMBASE, MEDLINE, CINAHL, CNKI, and Google Scholar were searched for relevant article retrieval. RESULTS A range of pharmaceutical, nutraceutical, and herbal medicine treatments were identified that either showed efficacy or had some evidence of efficacy. Duloxetine was the most effective pharmaceutical agent for the treatment of CIPN. Vitamin E demonstrated potential for the prevention of cisplatin-IPN. Intravenous glutathione for oxaliplatin, Vitamin B6 for both oxaliplatin and cisplatin, and omega 3 fatty acids for paclitaxel have shown protection for CIPN. Acetyl-L-carnitine may provide some relief as a treatment option. Acupuncture may be of benefit for some patients and Gosha-jinki-gan may be of benefit for protection from adverse effects of oxaliplatin induced peripheral neuropathy. CONCLUSIONS Clinicians and researchers acknowledge that there are numerous challenges involved in understanding, preventing, and treating peripheral neuropathy caused by chemotherapeutic agents. New insights into mechanisms of action from chemotherapy agents may facilitate the development of novel preventative and treatment options, thereby enabling medical staff to better support patients by reducing this debilitating side effect.

Abstract
BACKGROUND Health care policies and guidelines that are clear and consistent with research evidence are important for maximizing clinical outcomes. To determine whether cancer centers in Canada and the United States had policies and/or guidelines about antioxidant use, and whether policies were aligned with the evidence base, we reviewed current research evidence in the field, and we undertook a survey of the policies and guidelines on antioxidant use at cancer institutions across North America. METHODS A survey of policies and guidelines on antioxidant use and the development and communication of the policies and guidelines was conducted by contacting cancer institutions in North America. We also conducted a Website search for each institution to explore any online resources. RESULTS Policies and guidelines on antioxidant use were collected from 78 cancer institutions. Few cancer institutions had policies (5%) but most provided guidelines (69%). Antioxidants from diet were generally encouraged at cancer institutions, consistent with the current research evidence. In contrast, specific antioxidant supplements were generally not recommended at cancer institutions. Policies and guidelines were developed using evidence-based methods (53%), by consulting another source (35%), or through discussions/conference (26%), and communicated mainly through online resources (65%) or written handouts (42%). For cancer institutions that had no policy or guideline on antioxidants, lack of information and lack of time were the most frequently cited reasons. CONCLUSIONS Policies and guidelines on antioxidants from diet were largely consistent with the research evidence. Policies and guidelines on antioxidant supplements during treatment were generally more restrictive than the research evidence might suggest, perhaps due to the specificity of results and the inability to generalize findings across antioxidants, adding to the complexity of their optimal and safe use. Improved communication of comprehensive research evidence to cancer institutions may aid in the development of more evidence-based policies and guidelines.

Abstract
Background Hand-foot syndrome (HFS) is a relatively frequent dermatologic toxic reaction to certain anti-cancer chemotherapies. The syndrome can evolve into a distressing condition that limits function and affects quality of life. Pyridoxine (vitamin B6) has been used empirically for the prevention of HFS caused by anti-cancer therapy. However, evidence of its efficacy remains controversial. Methodology//Principal Findings Systematic literature searches were conducted on the Cochrane Library, PUBMED, EMBASE, LILACS, CBM, CNKI, VIP, WANFANG and the U.S. ClinicalTrials.gov website. We included all related randomized controlled trials (RCTs) irrespective of language. Reviewers from different professions independently assessed all potential studies and extracted data. Subgroup analysis was planned according to dose of pyridoxine. 5 RCTs involving 607 patients were contributed to the meta-analysis. No significant differences were found between patients receiving pyridoxine and placebo for prevention of incidence of HFS and grade 2 or worse HFS (relative risk (RR) 0.96, 95%confidence interval (CI) 0.86–1.06; RR0.95, 95%CI 0.73–1.24, respectively). Similarly, no significant improvement in quality of life was detected among patients. However, significant difference was found for prevention of grade 2 or worse HFS with pyridoxine 400 mg daily compared to 200 mg (RR0.55, 95%CI 0.33–0.92). Conclusions/Significance There is inadequate evidence to make any recommendation about using pyridoxine for prevention of HFS caused by chemotherapy. However, pyridoxine 400 mg may have some efficacy. Further studies of large sample sizes are needed to evaluate the efficacy and safety of pyridoxine, especially at high dose, in comparison with placebo.

Abstract
Chemotherapy induced peripheral neuropathy [CIPN] is a common significant and debilitating side effect resulting from the administration of neurotoxic chemotherapeutic agents. These pharmaco-chemotherapeutics can include taxanes, vinca alkaloids and others. Moderate to severe CIPN significantly decreases the quality of life and physical abilities of cancer patients and current pharmacotherapy for CIPN e.g. Amifostine and antidepressants have had limited efficacy and may themselves induce adverse side effects. To determine the potential use of nutraceuticals i.e. vitamin E, acetyl-L-carnitine, glutamine, glutathione, vitamin B6, omega-3 fatty acids, magnesium, calcium, alpha lipoic acid and n-acetyl cysteine as adjuvants in cancer treatments a systematic literature review was conducted. Revised clinical studies comprised of randomized clinical trials that investigated the anti-CIPN effect of nutraceuticals as the adjuvant intervention in patients administered chemotherapy. Twenty-four studies were assessed on methodological quality and limitations identified. Studies were mixed in their recommendations for nutraceuticals. Currently no agent has shown solid beneficial evidence to be recommended for the treatment or prophylaxis of CIPN. The standard of care for CIPN includes dose reduction and/or discontinuation of chemotherapy treatment. The management of CIPN remains an important challenge and future studies are warranted before recommendations for the use of supplements can be made.

Abstract
Background Ovarian cancer stem cells are characterized by self-renewal capacity, ability to differentiate into distinct lineages, as well as higher invasiveness and resistance to many anticancer agents. Since they may be responsible for the recurrence of ovarian cancer after initial response to chemotherapy, development of new therapies targeting this special cellular subpopulation embedded within bulk ovarian cancers is warranted. Methods A high-throughput screening (HTS) campaign was performed with 825 compounds from the Mechanistic Set chemical library [Developmental Therapeutics Program (DTP)/National Cancer Institute (NCI)] against ovarian cancer stem-like cells (CSC) using a resazurin-based cell cytotoxicity assay. Identified sets of active compounds were projected onto self-organizing maps to identify their putative cellular response groups. Results From 793 screening compounds with evaluable data, 158 were found to have significant inhibitory effects on ovarian CSC. Computational analysis indicates that the majority of these compounds are associated with mitotic cellular responses. Conclusions Our HTS has uncovered a number of candidate compounds that may, after further testing, prove effective in targeting both ovarian CSC and their more differentiated progeny.

Abstract
BACKGROUND Pyridoxine is frequently used to treat capecitabine-induced hand-foot syndrome (HFS), although the evidence of benefit is lacking. We performed a randomised placebo-controlled trial to determine whether pyridoxine could avoid the need for capecitabine dose modifications and improve outcomes. METHODS A total of 106 patients planned for palliative single-agent capecitabine (53 in each arm, 65%/35% colorectal/breast cancer) were randomised to receive either concomitant pyridoxine (50 mg po) or matching placebo three times daily. RESULTS Compared with placebo, pyridoxine use was associated with an increased rate of avoiding capecitabine dose modifications (37% vs 23%, relative risk 0.59, 95% CI 0.29, 1.20, P=0.15) and fewer grade 3/4 HFS-related adverse events (9% vs 17%, odds ratio 0.51, 95% CI 0.15-1.6, P=0.26). Use of pyridoxine did not improve response rate or progression-free survival. CONCLUSION Pyridoxine may reduce the need for capecitabine dose modifications and the incidence of severe HFS, but does not impact on antitumour effect.

Abstract
Palmar-plantar erythrodysesthesia, or hand-foot syndrome (HFS), is emerging as a common, dose-dependent toxicity of many newer chemotherapy drugs. Frequently, HFS is a dose-limiting toxicity requiring discontinuation of treatment, chemotherapy dose reductions, or delays. The spectrum of symptoms of HFS can be mild, with erythema of the distal extremities, or it can be severe enough to interfere with activities of daily living. Although the exact mechanism is unknown, there are several approaches to ameliorating the symptoms of this complication. These include antiinflammatory agents, vitamin products, and peripheral vasoconstricting agents.

Abstract
AIM The aim of the present study was to compare the efficacy of 200 mg versus 400 mg daily of pyridoxine in preventing or delaying the onset of palmar-plantar erythrodysesthesia (PPE) in capecitabine-treated patients. METHODS Patients with histologically confirmed breast cancer or colorectal cancer receiving single agent capecitabine started at 2000 to 2500 mg/m(2) daily from day 1 to 14 every 3 weeks were randomly assigned to receive 200 mg or 400 mg daily of pyridoxine for PPE prophylaxis. The primary endpoint was the reduction of incidence of grade 2 or greater PPE. Secondary endpoints were reduction of severe PPE and prolongation of time to development of grade 2 or greater PPE. RESULTS There were 56 patients in this study. The baseline characteristics were generally similar in both groups. The high dose arm had less PPE than the low dose arm (11 of 28 or 39% vs 20 of 28 or 71%, relative risk = 0.26 [0.08, 0.79], P = 0.031). Grade III PPE developed in 3 of 28 (10.7%) versus none in patients receiving 200 mg versus 400 mg pyridoxine, respectively (relative risk 2.12 [1.594, 2.819], P = 0.24). High dose pyridoxine had a longer time to development of grade 2 or greater PPE compared to the low dose arm, 87 days versus 62 days. The 400 mg pyridoxine group had, however, a worsened tumor response and tended to have greater tumor treatment failure and shorter time to treatment failure. CONCLUSION With the limitation of sample size in this study, there was a trend to improve PPE incidence and time to event with a higher dose of pyridoxine. Further validation of these results in a larger population is warranted.

Abstract
PURPOSE Oxaliplatin (OHP) in combination with 5-fluorouracil/leucovorin (FOLFOX) is clinically used as frontline therapy in patients with advanced colorectal carcinoma (CRC), with response rates ranging from 46 to 71%. This combination is now considered a standard treatment for metastatic CRC and also in the post-operative adjuvant setting. Reversible, cumulative, peripheral sensory neuropathy is the principal dose-limiting toxicity of OHP therapy. Pyridoxine (vitamin B6) has been shown to reduce cisplatin and fluoropyrimidine-related neurotoxicity but its administration with OHP has not yet been studied. Low doses of pyridoxine are free of side effects; it can be given orally. If pyridoxine administration with oxaliplatin has no adverse effect on OHP cytotoxicity effects, it will be a simple and cost-effective way to minimise OHP-induced neurotoxicity. METHODS In vitro simultaneous combination of OHP and pyridoxine was studied in 6 CRC cell lines (HT29, Widr, SW480, HCT116, H630 and SW1116), in an ovarian cancer cell line (A2780) and its cisplatin-resistant subline (ADDP) and in an oestrogen-dependent breast cancer cell line (MCF-7). Three fixed concentrations of pyridoxine: 1, 10 and 25 μM were combined with varying concentrations of OHP, and the growth inhibitory effects were evaluated using the MTT cell growth assay. RESULTS Oxaliplatin induced consistent cytotoxicity in all cell lines with GI(50) values between 0.23 and 7.6 μM. Addition of pyridoxine at concentrations of 1-25 μM does not affect OHP cytotoxicity. CONCLUSIONS Administration of pyridoxine, at concentrations extending across possible therapeutic plasma levels in humans, does not antagonise OHP antitumour effects in a range of relevant tumour cell lines. This study provides a foundation for clinical studies to test whether pyridoxine can minimise OHP-related neurotoxicity, and clinicians can be confident that pyridoxine is very unlikely to reverse the antitumour effects of OHP, as seems to be the case with Ca/Mg infusions. This could prove to be a cost-effective way to minimise OHP-related neurotoxicity, allowing more effective less toxic treatment and better outcomes in patients.

Abstract
Purpose To determine whether concurrent pyridoxine therapy can prevent the development of hand-foot syndrome (HFS) in patients being treated with capecitabine. Methods Chemotherapy-naive patients with GI tract cancers scheduled for capecitabine-containing chemotherapy were randomly assigned to concurrent oral pyridoxine (200 mg/d) or placebo. Patients were stratified by chemotherapy regimen and monitored until development of National Cancer Institute Common Toxicity Criteria grade 2 or worse HFS or capecitabine-containing chemotherapy ended. Patients in the placebo group who developed grade 2 or worse HFS were randomly assigned again to receive pyridoxine or placebo in the next chemotherapy cycle to determine whether pyridoxine could improve HFS. Results The median number of chemotherapy cycles to grade 2 or worse HFS was three in both groups. Grade 2 or worse HFS developed in 55 (30.6%) of 180 placebo-treated patients and in 57 (31.7%) of 180 pyridoxine patients. The cumulative dose of capecitabine to grade 2 or worse HFS was not different between the two groups (median not reached in either group; hazard ratio [HR] = 0.95; P = .788). Randomization of the 44 patients in the placebo group with grade 2 or worse HFS to placebo or pyridoxine for the next cycle resulted in no significant difference in the proportion showing improvement of HFS (42.9% v 47.8%; HR = 1.12; P = .94). By multivariate analysis, age ≥ 56 years (HR = 1.768; 95% CI, 1.190 to 2.628; P = .005) was an independent risk factor for grade 2 or worse HFS, and combined use of docetaxel (HR = 2.046; 95% CI, 0.880 to 4.755; P = .096) was of borderline significance. Conclusion Pyridoxine is not effective in prevention of capecitabine-associated HFS.

Abstract
Despite nearly two decades of research investigating the use of dietary antioxidant supplementation during conventional chemotherapy and radiation therapy, controversy remains about the efficacy and safety of this complementary treatment. Several randomized clinical trials have demonstrated that the concurrent administration of antioxidants with chemotherapy or radiation therapy reduces treatment-related side effects. Some data indicate that antioxidants may protect tumor cells as well as healthy cells from oxidative damage generated by radiation therapy and some chemotherapeutic agents. However, other data suggest that antioxidants can protect normal tissues from chemotherapy- or radiation-induced damage without decreasing tumor control. We review some of the data regarding the putative benefits and potential risks of antioxidant supplementation concurrent with cytotoxic therapy. On the basis of our review of the published randomized clinical trials, we conclude that the use of supplemental antioxidants during chemotherapy and radiation therapy should be discouraged because of the possibility of tumor protection and reduced survival.

Abstract
Although the role of systemic chemotherapy has been established for the treatment of advanced gastric cancer, the prognosis of these patients remains poor, with a median overall survival of less than 1 year. Based on the results of several randomized Phase III trials, 5-fluorouracil continuous infusion plus cisplatin, with or without epirubicin, has become the global reference regimen for this patient population. However, treatment with fluorouracil infusion requires either frequent hospitalizations or the use of a central venous access device, harboring potential complications. Capecitabine, a tumor-activating oral prodrug of fluorouracil, may be more advantageous in terms of patient convenience, safety and efficacy. Two recent randomized Phase III trials have shown that capecitabine could replace infusional fluorouracil in cisplatin-based regimens. Furthermore, Phase II trials have shown that many other capecitabine-based doublet or triplet chemotherapy regimens incorporating newer cytotoxic agents are active and well tolerated. Many promising biological agents are now being tested in Phase III trials, incorporating capecitabine combinations as control arms, in patients with advanced gastric cancer.

Abstract
STUDY OBJECTIVES To determine the frequency and type of complementary and alternative medicine (CAM) use among healthy volunteers participating in research, and to investigate the potential for interactions between commonly used CAM modalities and various drugs. DESIGN Prospective evaluation. SETTING University general clinical research center. SUBJECTS Sixty healthy adults participating in an ongoing drug study. MEASUREMENTS AND MAIN RESULTS The clinical study database was queried to determine the use and type of existing and newly started CAM throughout the study period. Baseline characteristics were compared between users and nonusers of CAM to identify differences between them. Potential CAM-drug interactions were classified based on curated databases and primary literature sources. Of the 60 subjects enrolled, 30 (50%) used CAM during the study. Of these, 26 (87%) were using CAM at study entry. Baseline CAM users were on average 7 years older than nonusers (p=0.03) and had high-density lipoprotein cholesterol concentrations 10 mg/dl higher than those of nonusers (p=0.04). The group using CAM had more women and nonsmokers than the other group. Several potential CAM-drug interactions were identified. CONCLUSION Because of high rates of CAM use (50% of the subjects were using biologically based CAM) and the many potential CAM-drug interactions, CAM use should be rigorously addressed in clinical practice and research. Failure to capture this information may have clinical repercussions through pharmacokinetic and pharmacodynamic interference of clinical response and clinical trial results. Clinicians and researchers may be able to identify those most likely to use CAM by their baseline characteristics; this would help target those patients and research subjects for more thorough assessment and follow-up.

Abstract
Laryngeal carcinoma is the 11th commonest form of cancer in men world-wide, with 121,000 new cases in 1985. More than 95% of all laryngeal malignancies are squamous cell carcinomas. Treatment indications in cancer of the larynx are often controversial, since there are few comparative studies of different available therapeutic approaches. Surgery and radiotherapy are both widely used, and the choice between these two procedures is the most common therapeutic decision which has to be taken. Laryngeal function preservation has gained more and more weight in the last decades and chemotherapy is also a significant component of several curative approaches. In the last decades, several organ-preserving surgical techniques have become available and consequently total laryngectomy results less applied. Regardless of the treatment modality, Tis, T1, T2 laryngeal carcinomas have an 80-90% probability of cure, whereas for more advanced tumours this is approximately 60%. The most effective approach to laryngeal cancer remains prevention and early diagnosis when this cancer is curable with function preserving treatments.

Abstract
BACKGROUND Although cis-diamminedichloroplatinum (II) (cisplatin) is an effective anticancer agent, its clinical use is highly limited predominantly due to its adverse effects on renal functions. The present work examined the therapeutic potential of edaravone, a free radical scavenger, for inhibiting cisplatin-induced renal injury. METHODS Edaravone, 3-methyl-1-phenyl-pyrazolin-5-one, was administrated intravenously at a dose of 30 mg/kg of body weight to male Wistar rats (200-220 g). After 30 min, cisplatin was injected intraperitoneally at a dose of 5 mg/kg of body weight. At the indicated times after the treatment, functions and histological changes of the kidney were analyzed. To test the therapeutic potential of edaravone in chemotherapy, its effect on the anticancer action of cisplatin was examined in ascites cancer-bearing rats. RESULTS We found that cisplatin rapidly impaired the respiratory function and DNA of mitochondria in renal proximal tubules, thereby inducing apoptosis of tubular epithelial cells within a few days and chronic renal dysfunction associated with multiple cysts one-year after the administration. Administration of edaravone inhibited the cisplatin-induced acute injury of mitochondria and their DNA and renal epithelial cell apoptosis as well as the occurrence of chronic renal dysfunction and multiple cyst formation. The anticancer effect of cisplatin remained unaffected by intravenous administrating of edaravone. CONCLUSIONS These results indicate that edaravone may have therapeutic potential for inhibiting the acute and chronic injury of the kidney induced by cisplatin.

Abstract
PURPOSE Capecitabine has demonstrated high efficacy as first-line treatment for metastatic colorectal cancer (MCRC). Oxaliplatin shows synergy with fluorouracil (FU), with little toxicity overlap. The XELOX regimen (capecitabine plus oxaliplatin), established in a previous dose-finding study, should improve on infused oxaliplatin with FU and leucovorin (FOLFOX) regimens. The present studies further characterize efficacy and safety of the XELOX regimen. PATIENTS AND METHODS The antitumor activity of XELOX was investigated in a colon cancer xenograft model. Patients with MCRC received first-line XELOX in 3-week treatment cycles: intravenous oxaliplatin 130 mg/m(2) (day 1) followed by oral capecitabine 1,000 mg/m(2) twice daily (day 1, evening, to day 15, morning). RESULTS A preclinical study confirmed that capecitabine has supra-additive activity with oxaliplatin. In the clinical study, 53 of 96 patients (55%) achieved an objective response, and 30 (31%) experienced disease stabilization for >/= 3 months following treatment. After 24 months' minimum follow-up, median time to disease progression (TTP) and median overall survival were 7.7 and 19.5 months, respectively. XELOX safety was predictable and similar to the FOLFOX4 regimen, except that myelosuppression was uncommon with XELOX (grade 3 or 4 neutropenia, 7%). Most adverse events were mild to moderate, the most common being acute sensory neuropathy (85%). Sixty-day, all-cause mortality was 2%. CONCLUSION XELOX is a highly effective first-line treatment for MCRC. Response rates, TTP, and overall survival are similar to those observed with FU/leucovorin/oxaliplatin combinations. XELOX provides a more convenient regimen, likely to be preferred by both patients and healthcare providers. Capecitabine has the potential to replace FU/LV in combination with oxaliplatin for MCRC.

Abstract
We recently reported the synthesis of a cationic superoxide dismutase (SOD) derivative (AH-SOD) that rapidly and selectively accumulates in and around proximal tubule cells and effectively dismutes superoxide radicals in situ. The present study revealed that administration of cis-diamminedichloroplatinum(II)-elicited oxidative stress in renal mitochondria, decreased the renal expression of Bcl-x, released cytochrome c from mitochondria to cytosol, and induced apoptosis and renal dysfunction by a mechanism that was inhibited by AH-SOD. These results suggest that targeting SOD to proximal tubule cells protects renal function and permits the administration of fairly high doses of nephrotoxic anticancer agents, such as cisplatin, without causing renal injury.

Abstract
Palmar plantar erythrodysesthesia (PPE) is a distinctive and relatively frequent toxic reaction related to some chemotherapeutic agents. Doxorubicin, cytarabine, docetaxel, and fluorouracil are the most frequently implicated agents. PPE seems to be dose dependent and both peak drug concentration and total cumulative dose determine its occurrence. PPE presents as a painful erythema, often preceded by paresthesia, located on the palms and soles in the context of treatment with chemotherapy. Histologically, PPE shows few specific findings. Mild spongiosis, scattered necrotic and dyskeratotic keratinocytes and vacuolar degeneration of the basal layer is seen. Dermal changes in most cases include dilated blood vessels, papillary edema, and a sparse superficial perivascular lymphohistiocytic infiltrate can be found in varying degrees in the epidermis. Withdrawal or dose reduction of the implicated drug usually gives rise to amelioration of the symptoms. Supportive treatments such as topical wound care, elevation, and cold compresses may help to relieve the pain. Use of systemic corticosteroids, pyridoxine (vitamin B6), blood flow reduction, and, recently, topical 99% dimethyl-sulfoxide have been used with variable outcomes. It could be of interest to consider them as preventive measures when drugs with a strong association with PPE are going to be administered.

Abstract
From December 1982 to December 1986, 52 patients with recurrent ovarian cancer were treated with single-agent HMM. Chemotherapy was given for a period of 1 year unless progression of disease or toxicity was noted. Survival was determined from the time of diagnosis to the date of death or September 30, 1992. The regimen was well tolerated with only one case of severe gastrointestinal toxicity. Nine patients were found to be clinically free of disease following completion of HMM treatment; they had initially responded to cisplatin-based therapy (i.e., potentially cisplatin-sensitive) and subsequently recurred. Four were found to have gross disease at the time of reassessment laparotomy. Three of these 9 patients are alive 81-92 months since diagnosis, having maintained disease-free intervals of up to 6 years. The median survival for the 9 patients without evidence of disease at the end of therapy was 75 months versus 9 months for the nonresponders. No patient who had progressive disease on first-line cisplatin-based combination chemotherapy (i.e., primary cisplatin-resistant) responded to second-line single-agent oral hexamethylmelamine. With a follow-up close to 10 years, our data show that hexamethylmelamine, with reasonable toxicity, can provide an extended, disease-free interval to a selected group of patients.

Abstract
27 patients with ovarian cancer FIGO stages IIc-IV were treated with carboplatin 7 x (glomerular filtration rate + 25) mg given intravenously on day 1 and hexamethylmelamine (HMM) 150 mg/m2 orally on days 2-15, every 28 days. 3 patients were not evaluable for response. Clinical response was seen in 17 patients (71%), with six (25%) complete and 11 (46%) partial responses. The median progression-free survival was 15.6 months and the median cancer-related survival was 21.3 months. 4 patients (15%) experienced grade 3 mental depression; none had peripheral neuropathy above grade 1. The haematological toxicity was moderate, none had grade 4 leucopenia, but 4 (15%) had grade 4 thrombocytopenia. Carboplatin plus HMM had few side-effects and a high response rate with a survival comparable to other platinum-based combinations.

Abstract
Altretamine (hexamethylmelamine) is a cytotoxic antineoplastic agent which appears to require metabolic activation. Metabolic intermediates may act as alkylating agents; however, altretamine is not directly cross-resistant with classical alkylating agents. Objective response rates to orally administered altretamine as salvage therapy in patients with advanced ovarian cancer were 0 to 33%, with disease stabilisation in a further 8 to 78% of patients. Response rates appear to be higher in patients who have responded to previous alkylating agent or cisplatin-based therapy. There is some evidence that addition of altretamine to platinum-based combination regimens used for induction therapy of advanced ovarian cancer may improve long term survival, particularly in patients with limited residual disease. Although altretamine displays some activity in small cell lung cancer, it is unlikely to have any clinical role in the management of non-ovarian cancer. Altretamine appears to be relatively well tolerated, with gastrointestinal, neurological and haematological toxicities being the main dose-limiting adverse effects. However, assessment of accurate incidence rates for these effects is complicated by the use of altretamine with cisplatin. On the basis of the emerging body of clinical evidence, altretamine appears to have a limited role in the treatment of persistent or recurrent advanced ovarian cancer, primarily in patients who are potentially platinum sensitive yet intolerant of platinum analogues. Additionally, altretamine may be added to platinum-based regimens for induction therapy of advanced ovarian cancer. At the doses currently recommended, altretamine offers a reasonably well tolerated regimen that can be administered orally and is suitable for use on an outpatient basis.

Abstract
Clinical trials with several toxicity protectors (cytoprotective or chemoprotective agents) have been performed during the past decade. These trials are quite complex since they must include sufficient dose-limiting events for study, and assessment of both toxicity (and therefore the efficacy of protection) and antitumor effects must be carried out. However, it is inevitable that with greater understanding of drug actions, one seeks to manipulate these for greater antitumor activity (biochemical modulation) or for lesser dose-limiting toxicity (cytoprotection) or for both. Examples of cytoprotective agents include dexrazoxane (ICRF-187), protecting against doxorubicin cardiotoxicity, and amifostine protecting against the myelosuppression of platinum and alkylating agents. In spite of the challenges encountered in the clinical development of these drugs, studies of cytoprotectors have led to a considerable understanding of important therapeutic issues and tangible clinical benefit in specific clinical situations.

Abstract
PURPOSE Dose intensity (DI, expressed in mg/m2/wk) may be an important factor in the clinical use of cisplatin (DDP). We have explored the shortening of the cycle interval as a way to increase the DI of DDP. PATIENTS AND METHODS DDP 180 mg/m2 was given intravenously (i.v.) over 4 hours; sodium thiosulfate (STS) was given i.v. in the opposite arm at a loading dose of 4 g/m2, followed by 12 g/m2 over 6 hours. Each cycle was repeated every two weeks. Seventy-five cycles were administered to 28 patients in this clinical trial. RESULTS In 19 patients who received 2 or more cycles of chemotherapy, a delay of three or more days was required on 17/66 courses (26%); the mean DDP DI actually received by these patients was 83 mg/m2/wk (88% of the planned DI). The major side effect was ototoxicity; this occurred in 9 patients (33%), but none required a hearing aid. Myelosuppression was moderate with thrombocytopenia greater than neutropenia. Nephrotoxicity (creatinine > 2 mg/dl) occurred on only 2 cycles (3%). Three patients (11%) developed symptoms of peripheral neuropathy. In 23 evaluable patients, the overall response rate was 39%. CONCLUSION It is feasible to give 180 mg/m2 of DDP and STS every two weeks with tolerable nephrotoxicity but without blocking other types of toxicity, such as myelosuppression and ototoxicity. The shortening of cycle intervals resulted in a markedly increased DI.
