Trial Outcomes & Findings for Phase II Study of Ixabepilone in Metastatic Breast Cancer and Its Effects on the Ultrastructure of Neurons (NCT NCT00627978)

NCT ID: NCT00627978

Last Updated: 2018-06-26

Results Overview

Digital photographs for morphometry were captured at a magnification of 8000-16,000x and the photos were uploaded onto an imaging platform of transmission electron microscope (iTEM) (Olympus, Mu¨nster, Germany). The figures were enlarged by 50%, and an individual linear array was used to measure the axonal diameter (cross-sectional area) and the number of unmyelinated axons per Remak Schwann cell was enumerated according to the established methodology.
