Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Potential patients were approached in the Dana-Farber Breast Oncology clinic and Newton Wellesley Hospital. Eligible patients were then presented with the study and given an opportunity to sign consent. The recruitment period ran from March 30th 2009 to May 1st, 2012.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
A total of 17 patients were enrolled in this study; however, only 16 patients started treatment. One patient withdrew from the study before starting treatment.

Reporting Groups
  Description
Letrozole-Leuprolide

Patients will receive 2.5mg oral letrozole daily and either 7.5mg monthly of Leuprolide IM or 22.5mg every three months of Leuprolide IM. Zoledronic acid 4mg IV every 6 months x 4 will also be offered optionally.

leuprolide: Given intramuscularly beginning on day 1 and then either 7.5 mg every month or 22.5 mg every 3 months for two years

letrozole: Taken orally once a day 6-8 weeks after initial leuprolide administration

zoledronic acid: If desired, given intravenously every 6 months for a total of 4 injections (optional)
