Trial Outcomes & Findings for Ultrasound in Detecting Taxane-Induced Neuropathy in Patients With Breast Cancer (NCT NCT03139435)

NCT ID: NCT03139435

Last Updated: 2024-04-08

Results Overview

Will be determined by ultrasound in the tibial nerve. Will be compared to the historical data from healthy patients using two-sample t-test (two-sample t-test selected as primary data from the historical control patients is available and will be used for analysis). Will also compare the nerve cross-sectional area in our study sample to that in the historical diabetic neuropathy patients and historical oxaliplatin neuropathy patients using one-sample t-test. The general linear model will be used to evaluate any factors (e.g., age) that may be associated with the nerve cross-sectional area. Due

Will be determined by ultrasound of the sural nerve. Spearman's rank correlation coefficient will be used to examine the associations between nerve cross-sectional area and nerve conduction studies. The general linear model will be also used to evaluate the association after adjusting for one or two risk factors (e.g., age). Nerve cross-sectional area will be treated as the dependent variable.
