The mu opioid receptor (MOR) and metabotropic glutamate receptor 5 (mGluR5) are well-established pharmacological targets in the management of chronic pain. Both receptors are expressed in spinal cord. MMG22, a bivalent ligand containing two pharmacophores separated by 22 atoms that simultaneously activates MOR and antagonizes mGluR5 has been shown to produce potent reversal of tactile hypersensitivity in rodent models of LPS- and bone-cancer-induced chronic pain. The present study assessed whether intrathecal MMG22 also is effective in reducing pain of neuropathic origin...

Cisplatin is an effective chemotherapeutic agent indicated in cancer chemotherapy. However, its clinical use is associated with peripheral neuropathy that invariably impairs patient quality of life. Gabapentin (GBP) is an effective analgesic for neuropathic pain conditions but its clinical efficacy in cisplatin-induced neuropathic pain (CINP) is limited, in addition to generating unwanted side-effects. In this study, a gabapentin-salicylaldehyde derivative [gabapentsal (GPS)] was synthesized and evaluated to explore any potential benefit in comparison with GBP in a rat model of CIPN...

INTRODUCTION: Management of patients with cancer suffering from neuropathic pain refractory to opioids and gabapentinoids remains an important challenge. Duloxetine is one of the choices after first-line treatment fails. The efficacy of duloxetine has been reported in patients with non-cancer disease and in chemotherapy-induced peripheral neuropathy, but no randomised clinical trials have examined its effects on neuropathic cancer pain refractory to first-line treatment. The objective of this study is to assess the analgesic efficacy of duloxetine in patients suffering from neuropathic cancer pain refractory to opioids and gabapentinoids...

Chemotherapy-induced neuropathic pain is a debilitating and common side effect of cancer treatment. Mitochondrial dysfunction associated with oxidative stress in peripheral nerves has been implicated in the underlying mechanism. We investigated the potential of melatonin, a potent antioxidant that preferentially acts within mitochondria, to reduce mitochondrial damage and neuropathic pain resulting from the chemotherapeutic drug paclitaxel. In vitro, paclitaxel caused a 50% reduction of mitochondrial membrane potential and metabolic rate, independent of concentration (20-100μM)...

CONTEXT: Neuropathic pain can be present in patients developing chemotherapy-induced peripheral neuropathy (CIPN). Nerve growth factor (NGF) is trophic to small sensory fibers and regulates nociception. OBJECTIVES: We investigated the changes in serum NGF and intraepidermal nerve fiber density (IENFD) in skin biopsies of cancer patients receiving neurotoxic chemotherapy in a single-center prospective observational study. METHODS: Patients were evaluated before and after chemotherapy administration...

BACKGROUND: For the treatment of patients with cancer to be successful and well-tolerated, the complications and side effects of the disease and its treatment must be treated and limited as far as possible. Summarized recommendations based on the constantly increasing evidence in the area of supportive care must be defined, standardized, and communicated. METHODS: We systematically reviewed the literature on the topics of anemia, neutropenia, nausea/vomiting, diarrhea, oral mucositis, skin toxicity, and peripheral neurotoxicity induced by cancer treatment, as well as osseous complications, extravasation, and side effects of radiotherapy...

Vincristine (VNC) is commonly used to treat pediatric cancers, including the most prevalent childhood malignancy, acute lymphoblastic leukemia. Although clinical evidence suggests that VNC causes peripheral neuropathy in children, the degree to which pediatric chemotherapeutic regimens influence pain sensitivity throughout life remains unclear, in part because of the lack of an established animal model of chemotherapy-induced neuropathic pain during early life. Therefore, this study investigated the effects of VNC exposure between postnatal days (P) 11 and 21 on mechanical and thermal pain sensitivity in the developing rat...

Background Paclitaxel is commonly used as a cancer chemotherapy drug that frequently causes peripheral neuropathic pain. Inflammasome is a multiprotein complex consisting of Nod-like receptor proteins (NLRPs), apoptosis-associated speck-like protein, and caspase-1, which functions to switch on the inflammatory process and the release of interleukin-1β. Growing evidences have supported that peripheral interleukin-1β is critical in enhancing paclitaxel-induced neuropathic pain. However, whether activation of NLRP3 inflammasome in peripheral nerve contributes to paclitaxel-induced neuropathic pain is still unclear...

Prokineticin1 and prokineticin2 belong to a new family of chemokines identified in several species including mammals and characterized by the presence of five disulfide bridges. These proteins signal through two G-coupled receptors (prokineticin-receptor1 and prokineticin-receptor2) widely expressed in all tissues and involved in a large spectrum of biological activities, including angiogenesis, hematopoiesis, immune processes, inflammation and nociceptive transmission. Prokineticin2 is overexpressed in inflamed tissues and has a crucial role in neutrophil dependent inflammation and hypernociception...

Many chemotherapy treatments induce peripheral neuropathy (CIPN). These patients often experience neuropathic pain (NP) that reduces the quality of life. The aim of this prospective, open label study was to evaluate the efficacy and tolerability of tapentadol (TP) in patients affected by CIPN. CIPN were consecutively enrolled in a prospective open label study at the Neuro-Oncology Unit of the Regina Elena National Cancer Institute in Rome. During the titration phase, each patient initially received doses of TP 50 mg twice a day...

Oxaliplatin (L-OHP) is a platinum-based anticancer agent used to treat various types of cancer. It frequently causes acute and chronic peripheral neuropathies, such as cold allodynia and mechanical hyperalgesia. Ninjin'yoeito (NYT) is a formula used in traditional Japanese Kampo medicine to improve recovery from diseases and other medical disorders. We previously reported that treatment with a boiling-water extract of NYT prevented L-OHP-induced damage to neurite-like outgrowths from differentiated PC12 cells...

BACKGROUND: Pain is still a burden for many patients with cancer. A recent trial showed superiority of methadone over fentanyl in neuropathic pain, and we expect that this could increase the amount of patients treated with methadone. METHODS: We performed a randomized controlled non-inferiority trial in patients with nociceptive pain. 82 strong-opioids naive patients with head-and-neck cancer with substantial pain (pain NRS≥4) due to radiation therapy were included...

Antimicrotubulin chemotherapeutic agents such as vincristine (VCR), often induce peripheral neuropathic pain. It is usually permanent and seriously harmful to cancer patients' quality of life and can result in the hampering of clinical treatments. Currently, there is no definitive therapy, and many of the drugs approved for the treatment of other neuropathic pain have shown little or no analgesic effect. It is therefore vital to find new and novel therapeutic strategies for patients suffering from chemotherapeutic agent-induced neuropathic pain to improve patients' quality of life...

Although cisplatin (CDDP) is a key drug in cancer chemotherapy, CDDP-induced peripheral neuropathy is a dose-limiting factor. We previously reported that CDDP-induced peripheral neuropathy, which progressed from allodynia to hypoalgesia, was ameliorated by the administration of CDDP to rats at a specific time. However, mechanical allodynia cannot be prevented therapeutically. Pregabalin (PGN) is used to suppress neuropathic pain from herpes zoster and diabetes. Therefore, we investigated the effects of PGN on CDDP-induced mechanical allodynia in rats...

Chemotherapeutic drugs, including bortezomib, often cause painful peripheral neuropathy, which is a severe dose-limiting adverse effect experienced by many cancer patients. The glutamate N-methyl-d-aspartate receptors (NMDARs) at the spinal cord level are critically involved in the synaptic plasticity associated with neuropathic pain. In this study, we determined whether treatment with bortezomib, a proteasome inhibitor, affects the NMDAR activity of spinal dorsal horn neurons. Systemic treatment with bortezomib in rats did not significantly affect postsynaptic NMDAR currents elicited by puff application of NMDA directly to dorsal horn neurons...

Despite affecting millions of people, chronic pain is generally treated insufficiently. A major point of focus has been the lack of translation from preclinical data to clinical results, with the predictive value of chronic pain models being a major concern. In contrast to current focus on stimulus-based nociceptive responses in preclinical research, development of behavioural tests designed to quantify suspension of normal behaviour is likely a more equivalent readout for human pain-assessment tests. In this study, we quantified grid-climbing behaviour as a non-stimulus-evoked behavioural test for potential use as a measure of neuropathic and cancer-induced bone pain in mice...

LESSONS LEARNED: Pregabalin is a medication that can decrease neuronal hyperexcitability, relieve neuropathic pain, and reach stable plasma levels after a titration period of only a few days.Its use during oxaliplatin infusions was not able to decrease the incidence of chronic, oxalipaltin-related neuropathic pain, compared with placebo. BACKGROUND: Patients with colorectal cancer (CRC) receiving oxaliplatin (OXA) develop acute and chronic painful oxaliplatin-induced peripheral neuropathy (OXAIPN)...

As inflammatory and immune responses are involved in pathophysiology of debilitating neuropathic pain, reagents that can modulate these two responses may have therapeutic potential. Morin, derived from the moraceae family of plants, benefits inflammation-related diseases, but its antinociceptive effects on cancer pain remain elusive. In the present study, we investigated antinociceptive effects of morin on bone cancer pain using a rat model, where rats were subject to implantation of Walker 256 mammary gland carcinoma cells into the tibia...

Preclinical Research The presence of pain as part of the cancer process is variable. Glioblastoma multiform (GBM) can produce bone metastasis, a condition that involves other pathological phenotypes including neuropathic and inflammatory pain. Tramadol and gabapentin are drugs used in the treatment of neuropathic pain. However, there are no studies evaluating their analgesic effects in bone metastasis. We produced a pain model induced by the inoculation of glioma cells (10(5) ) into the rat femur, by perforating the intercodiloid fossa...
