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.

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists

Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy.  SP binds and activates...

Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists01:29

Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists

Dopamine receptor antagonists, also known as antipsychotic agents, are critical in managing chemotherapy-induced vomiting. These antiemetic agents block dopamine receptors in the chemoreceptor trigger zone (CTZ), inhibiting signal transmission to the vomiting center. Antipsychotic agents encompass phenothiazines (PTZ), butyrophenones, benzamides, and thienobenzodiazepines (Zyprexa), which are utilized for their antiemetic and sedative properties.
Phenothiazines, such as prochlorperazine...

Pharmacokinetics in Pediatric Patients: Drug Distribution

Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight,...

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids01:21

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

Tetrahydrocannabinol (THC) is a phytocannabinoid that primarily interacts with the CB1 receptor, a type of G protein-coupled receptor (GPCR) predominantly in and around the chemoreceptor trigger zone (CTZ) and emetic center. THC also blocks the serotonin receptor activity in the dorsal vagal complex (DVC) by inhibiting serotonin release. THC exerts its anti-emetic effects through these interactions, which are beneficial for patients undergoing chemotherapy.
Two synthetic agonists of THC,...

Pharmacokinetics in Pediatric Patients: Drug Metabolism

In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses...

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
