Trial Outcomes & Findings for Development of Vitamin D as a Therapy for Breast Cancer - Phase 2 (NCT NCT00656019)

NCT ID: NCT00656019

Last Updated: 2017-12-02

Results Overview

Vitamin D levels in serum were correlated to classic prognostic and predictive factors for breast cancer, and the gene expression profile of breast core biopsy specimens. The outcome is reported as the proportion of subjects with a discernible pattern for expression of the set of 40 evaluated genes
