Purpose Of Review:
This review discusses publications highlighting current research on toxic, chemotherapy-induced peripheral neuropathies (CIPNs), and drug-induced peripheral neuropathies (DIPNs).
Recent Findings:
The emphasis in clinical studies is on the early detection and grading of peripheral neuropathies, whereas recent studies in animal models have given insights into molecular mechanisms, with the discovery of novel neuronal, axonal, and Schwann cell targets. Some substances trigger inflammatory changes in the peripheral nerves. Pharmacogenetic techniques are underway to identify genes that may help to predict individuals at higher risk of developing DIPNs. Several papers have been published on chemoprotectants; however, to date, this approach has not been shown effective in clinical trials.
Summary:
Both length and nonlength-dependent neuropathies are encountered, including small-fiber involvement. The introduction of new diagnostic techniques, such as excitability studies, skin laser Doppler flowmetry, and pharmacogenetics, holds promise for early detection and to elucidate underlying mechanisms. New approaches to improve functions and quality of life in CIPN patients are discussed. Apart from developing less neurotoxic anticancer therapies, there is still hope to identify chemoprotective agents (erythropoietin and substances involved in the endocannabinoid system are promising) able to prevent or correct painful CIPNs.

Area of Science:
- Neuroscience
- Pharmacology
- Oncology
Background:
- Peripheral neuropathies, including chemotherapy-induced (CIPN) and drug-induced (DIPN), are significant clinical challenges.
- Current research investigates the molecular mechanisms underlying these conditions.
Purpose of the Study:
- To review current research on toxic CIPNs and DIPNs.
- To highlight advancements in early detection, molecular mechanisms, and therapeutic strategies.
Main Methods:
- Review of recent publications on CIPN and DIPN.
- Analysis of clinical studies focusing on detection and grading.
- Examination of animal model studies for molecular insights.
- Evaluation of pharmacogenetic approaches and chemoprotectant research.
Main Results:
- Clinical studies emphasize early detection and grading of neuropathies.
- Animal models reveal novel neuronal, axonal, and Schwann cell targets.
- Inflammatory changes in peripheral nerves are observed with certain substances.
- Pharmacogenetics aims to identify high-risk individuals for DIPNs.
- Chemoprotectant trials have not yet proven effective.
Conclusions:
- Peripheral neuropathies involve length-dependent, nonlength-dependent, and small-fiber types.
- New diagnostic techniques (excitability studies, Doppler flowmetry, pharmacogenetics) aid early detection and mechanistic understanding.
- Approaches to improve function and quality of life in CIPN patients are discussed.
- Developing less neurotoxic therapies and identifying effective chemoprotective agents (e.g., erythropoietin, endocannabinoid system modulators) offer hope for preventing or correcting painful CIPNs.
