Although diabetic peripheral neuropathy (DPN) and chemotherapy-induced peripheral neuropathy (CIPN) are different disease entities, they share similar neuropathic symptoms that impede quality of life for these patients. Despite having very similar downstream effects, there have been no direct comparisons between DPN and CIPN with respect to symptom severity and therapeutic responses. We compared peripheral nerve damage due to hyperglycemia with that caused by paclitaxel (PAC) treatment as represented by biochemical parameters, diverse sensory tests, and immunohistochemistry of cutaneous and sciatic nerves...

Chemotherapy-induced peripheral neuropathy (CIPN) represents a serious complication associated with anticancer drugs. Although there are no medications available that effectively prevent CIPN, many classes of drugs have been used to treat this condition, including anticonvulsants, serotonin and noradrenaline reuptake inhibitors, and opioids. However, these theraputic options yielded inconclusive results in CIPN clincal trials and produce assorted side effects with their prolonged use. Thus, there is an urgent need to develop efficacious and safe treatments for CIPN...

Chemotherapy-induced peripheral neuropathy (CIPN) is a potentially debilitating side effect of a number of chemotherapeutic agents that does not have any FDA-approved interventions or prevention strategies. Although the cellular mechanisms mediating CIPN remain to be determined, several lines of evidence support the notion that DNA damage may be a causative factor in neuropathy induced by a number of cancer therapies. Therapies including platinum agents and ionizing radiation cause DNA damage in sensory neurons and augmenting key steps in the base excision repair (BER) pathway reverses this damage...

Breast cancer is the most common cancer in women worldwide, with an incidence of 1.7 million in 2012. Breast cancer and its treatments can bring along serious side effects such as fatigue, skin toxicity, lymphedema, pain, nausea, etc. These can substantially affect the patients' quality of life. Therefore, supportive care for breast cancer patients is an essential mainstay in the treatment. Low-level light therapy (LLLT) also named photobiomodulation therapy (PBMT) has proven its efficiency in general medicine for already more than 40 years...

Chemotherapy-induced peripheral neuropathy (CIPN) is a common toxicity associated with chemotherapy, but researchers rarely study its risk factors, fall risk, and prevalence in long-term breast cancer survivors. We aimed to determine CIPN prevalence, risk factors, and association with psychological distress and falls among long-term breast cancer survivors. We conducted Cross-sectional analyses among postmenopausal women with a history of stage I-III breast cancer who received taxane-based chemotherapy. Participants reported neuropathic symptoms of tingling/numbness in hands and/or feet on a 0-10 numerical rating scale...

Chemotherapy-induced peripheral neuropathy (CIPN) is one of the most frequent neurologic complications experienced by patients receiving antineoplastic drugs. Involvement of the peripheral nerves may have an important impact on daily activi-ties and lead to severe impairment of the patient's quality of life (QoL). It seems to be of crucial importance to make a correct and early diagnosis of polyneuropathy and, if possible, spare the patient unnecessary suffering or loss of function. In the preceding article we have presented epidemiology, grading and pathogenesis of the toxic CIPN...

Chemotherapy may have detrimental effects on either the central or peripheral nervous system. Central nervous system neurotoxicity resulting from chemotherapy manifests as a wide range of clinical syndromes including acute, subacute, and chronic encephalopathies, posterior reversible encephalopathy, acute cerebellar dysfunction, chronic cognitive impairment, myelopathy, meningitis, and neurovascular syndromes. These clinical entities vary by causative agent, degree of severity, evolution, and timing of occurrence...

Chemotherapy-induced peripheral neurotoxicity (CIPN) seriously impairs patients' quality of life cumulatively and dose-dependently. Because assessment of CIPN usually depends on patients' subjective evaluation of symptoms, objective and quantitative measures are needed. We evaluated a point-of-care nerve conduction device (POCD), previously validated for the assessment of diabetic peripheral neuropathy. Sensory nerve action potential (SNAP) amplitude and sensory nerve conduction velocity (SNCV) of the sural nerve were measured using a portable, automated POCD (DPNCheck(®) , NeuroMetrix Inc...

Chemotherapy-induced peripheral neuropathy (CIPN) is one of the most important neurologic complications experienced by patients receiving chemotherapy. The neuropathy often interferes with daily activities and exercise leading to severe impairment of the patient's quality of life (QoL). The evolution of most CIPNs is characterized by a gradual onset of signs/symptoms, beginning in the lower limbs and advancing proximally into a bilateral stocking and glove distribution. Patients often complain of numbness, tingling and pain in the affected areas...

The phosphorylated form of the high-molecular-weight neurofilament heavy subunit (pNF-H) is a major structural protein in axons. The pNF-H level is elevated in the serum of certain patients with central nervous disorders, including chemotherapy-induced cognitive impairment. The present study was conducted to elucidate the potential role of pNF-H as a marker of chemotherapy-induced peripheral neuropathy (CIPN). A total of 71 patients with early breast cancer in various stages of treatment (following 1, 3 or 7 cycles of chemotherapy, or a previous history of breast cancer chemotherapy) were assessed with a self-administered PainDETECT questionnaire [pain location, pain intensity on an 11-point numeric rating scale (NRS), and various pain qualities] and a single serum pNF-H measurement...

Chemotherapy-induced peripheral neuropathy (CIPN) is a frequent adverse event. Nutritional status can become impaired in cancer patients, potentially contributing to neuropathy's evolution. Our aim was to evaluate serum micronutrients and prealbumin in a cohort of 113 solid-cancer patients receiving platinum and taxane compounds during the development and recovery of neuropathy, up to 1 year after finishing treatment. CIPN was graded according to Total Neuropathy Score(©) and NCI.CTCv3 at T0 (baseline), T1 (1-3 months), and T12 (12 months) after chemotherapy...

Longer remissions and better overall survival rates can be achieved with the introduction of new, effective treatments and targeted therapies in the past 1-2 decades, however, the incidence of side effects is also increasing parallelly. Chemotherapy-induced peripheral neuropathy (CIPN) is a common and potentially debilitating side effect due to peripheral somatic or autonomic nerve dysfunction. CIPN becomes increasingly important, as it affects patients' quality of life, and it is very often a dose limiting factor with the potential for reduced treatment efficacy...
