Insights
Vincristine-induced peripheral neuropathy (VIPN) in children is a significant concern. This review identifies patient factors, VCR dose, and genetics influencing VIPN, aiming for safer, personalized chemotherapy.
Area of Science:
- Pediatric Oncology
- Neuroscience
- Pharmacology
Background:
- Vincristine (VCR) is a crucial chemotherapy agent for pediatric cancers.
- Vincristine-induced peripheral neuropathy (VIPN) is a common, dose-limiting side effect impacting children's quality of life.
- The precise mechanisms and contributing factors of VIPN in pediatric populations remain incompletely understood.
Purpose of the Study:
- To systematically review and synthesize existing literature on factors influencing VIPN development in children.
- To identify patient characteristics, treatment variables, and genetic predispositions associated with VIPN.
- To evaluate current methods for assessing VIPN in pediatric patients.
Main Methods:
- Systematic literature review of 28 publications.
- Analysis of studies examining patient demographics, VCR dosage and administration, pharmacokinetics, and genetic factors.
- Assessment of tools used for VIPN evaluation in children.
Main Results:
- Factors associated with increased VIPN risk include Caucasian race, higher VCR dose, and older age; however, findings for age and clearance were conflicting.
- Specific genetic pathways implicated in VIPN development were identified.
- Significant heterogeneity in VIPN assessment tools hinders cross-study comparability.
Conclusions:
- Understanding the multifactorial influences on VIPN in children is essential for optimizing VCR therapy.
- Personalized VCR treatment strategies, informed by patient-specific factors, can enhance efficacy and minimize neurotoxicity.
- Standardization of VIPN assessment tools is needed to improve research consistency and clinical management.
Abstract:
Vincristine-induced peripheral neuropathy (VIPN) is a dose-limiting side effect of vincristine (VCR) treatment in children, leading to diminished quality of life. Much remains unknown about the underlying mechanisms of VIPN. This review systematically summarizes the available literature concerning contributing factors of VIPN development in children. Studied factors include patient characteristics, VCR dose, administration method, pharmacokinetics, and genetic factors. Furthermore, this review reports on currently available tools to assess VIPN in children. In total, twenty-eight publications were included. Results indicate that Caucasian race, higher VCR dose, older age and low clearance negatively influence VIPN, although results regarding the latter two factors were rather conflicting. Moreover, genetic pathways influencing VIPN were identified. Furthermore, the studied tools to assess VIPN seriously impairs comparability across study results. Studying the factors and their interactions that seem to influence VIPN in children, should aid in personalized VCR treatment, thereby increasing VCR effectiveness while minimizing toxicity.
