neurotoxicity chemotherapy symptoms

No effective treatments are available for alleviating persistent symptoms of chemotherapy-induced peripheral neurotoxicity. 2019 Feb;98(2):240-249. doi: 10.1111/aogs.13477. Moreover, the markedly different perception of CIPN severity using physician-assessed measures (e.g., the widely used National Cancer Institute Common Toxicity Criteria [NCI-CTC] adverse events scale and the more comprehensive Total Neuropathy Score, clinical version) or patient-reported outcome measures (e.g., the European Organisation for Research and Treatment of Cancer [EORTC] QLQ-C30 and CIPN20 modules) is emerging very clearly. Honoraria: None. It occurs when exposure to a substance – specifically, a neurotoxin or neurotoxicant– alters the normal activity of the nervous system in such a way as to cause permanent or reversible damage to nervous tissue. May 14, 2015. The cure of cancer frequently is based on complex, hazardous, and toxic treatments, which are accepted because of their potential life-saving effects. A careful drug history should be taken, including recent administration of narcotic analgesia and antiemetic cover, used frequently for cancer patients undergoing chemotherapy and/or for symptom control. Acupuncture is effective for the prevention of neurotoxicity caused by oxaliplatin-based chemotherapy. The availability of large registries of patients with cancer who were carefully observed—such as the Patient-Reported Outcomes Following Initial Treatment and Long-Term Evaluation of Survivorship (PROFILES) registry—has allowed investigations on the persistence of CIPN-related long-term effects in several cancer types and, therefore, on the relationship existing with different treatments. JCO Oncology Practice To achieve a proper understanding of the long-term effects of CIPN, knowledge of the basic pathogenetic and clinical features related to the use of the different neurotoxic dugs is necessary. 22 Patients may also develop acute confusion in the absence of cerebellar signs, which may … Spinal cord toxicity can occur following intrathecal administration of certain cytotoxics in acute leukemias, lymphomas, and brain tumors. All of the subscales of the short-form (SF)-36 were significantly associated with the presence and severity of CIPN, but no objective assessment of CIPN presence was included in the study design. Patients present with cognitive deficits, which may progress to dementia, coma, and death.10–14 MRI imaging shows widespread changes throughout the white matter,15–18 and histologically, there is axonal swelling, demyelination, and neuronal death.19 Those most at risk are patients treated with methotrexate or cytarabine, particularly if given intrathecally or if cranial radiotherapy preceded cytotoxic administration.9 Elderly patients with primary central nervous system lymphoma undergoing treatment with high-dose methotrexate and whole-brain radiotherapy (WBRT) are at particularly high risk of developing this complication.20 There is no specific therapy that can halt the progressive decline, and overall the prognosis is poor. Leukoencephalopathy may follow on from acute encephalopathy, but may also be the first indication of neurotoxicity several months to years after administration of cytotoxic drugs. Relationships are considered self-held and compensated unless otherwise noted. Neurotoxicity with chemotherapy is common and second only to myelosuppression as a reason to limit dosing. Chemotherapy-Induced Peripheral Neurotoxicity in CancerSurvivors: An Underdiagnosed Clinical Entity? In rarer situations, this can be due to paraneoplastic syndromes, which tend to have a subacute onset and may be associated with the presence of antineuronal antibodies. Central neurotoxicity of chemotherapy, neurotoxic agents & consequences. There is no universal grading system for the evaluation of patients with neurological toxicity although two neurotoxicity scoring systems are frequently used: NCI-CTC 3 (National Cancer Institute Common Toxicity Criteria version 3) and ECOG (Eastern Cooperative Oncology Group).
