What the trial was testing
The trial enrolled 1,803 patients with colorectal cancer. The study was sponsored by Austrian Breast & Colorectal Cancer Study Group and tracked outcomes across the full group of patients who matched the trial's eligibility profile.
It was a large trial designed to confirm whether the treatment works well enough for wider use. Trials at this stage are designed to produce evidence regulators and physicians can act on — not just observations to follow up later.
What the results showed
Adding zoledronic acid reduced the risk of cancer returning by 36% compared to hormone therapy alone.
The New England journal of medicine · 2009 · NCT00295646
These findings — that women who got zoledronic acid with hormone therapy had over a third less risk of their cancer coming back. — were published in the The New England journal of medicine and represent the headline result of the study.
Researchers tracked outcomes across 1,803 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.
What this means for patients
For patients with colorectal cancer, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.
What you can do now
Zoledronic acid is FDA-approved for bone health in cancer patients and is sometimes used alongside hormone therapy for breast cancer. This was a large-scale study showing it may help prevent cancer recurrence. If you're premenopausal with hormone-responsive breast cancer, ask your oncologist whether adding zoledronic acid to your hormone treatment could be right for you.
