To Study the Individual Variants of Chemotherapy-Induced Neurotoxicity

Integrating Clinical and Genomic Profiles for Prediction and Prevention of Chemotherapy-induced Neuropathy Via Big Bio-Data Analytics

To study the risk prediction of chemotherapy-induced peripheral neuropathy (CIPN) by the clinical bioinformatics and genomic profile.

Study Overview

• Status: Active, not recruiting
• Conditions: Neurotoxicity Syndromes
• Intervention / Treatment: Other: Questionnaires; Procedure: Peripheral nervous system examination; Genetic: Whole Genome Sequence

Detailed Description

This is a prospective, observational, cohort study, monitoring the chemotherapy-induced peripheral neurotoxicity by traditional clinical scales, neurological examinations, and semi-quantitative assessments. Moreover, all the genetic changes will be analyzed by next generation sequencing and we will try to identify relevant variants in individuals who suffer from chemotherapy-induced neurotoxicity.
