Last Updated: 2014-04-24

Results Overview

17 women with early breast cancer receiving adjuvant Aromatase Inhibitor (AI) therapy were treated with a single 5 mg IV dose of zoledronic acid. Urine and serum NTx and serum CTx were measured at baseline and month 12.

Participant Flow

Recruitment period was from 1/10/2007 for first patient consented to 12/29/2009 last patient consented. The patients were all seen in the Milton S. Hershey Medical Center Oncology clinic \& were treated from first patient Day 1 of 1/16/2007 to last patient month 12 of 2/01/2011.

Following consent, this trial only had 1 arm \& all patients were given a one time dose of Zoledronic Acid 5 mg IV. All 17 patients were then followed for 12 months from day 1 \& their urine \& serum were collected in order to evaluate the urine N-telopeptide (NTx) \& serum NTx \& C-telopeptide (CTx) levels.
