Study Details

Brief summary:

The purpose of the clinical study is to investigate whether the local delivery of bisphosphonate as a surgical adjuvant can decrease the chance of a giant cell tumor of bone coming back to the same location. The hypothesis is that the local administration of bisphosphonate will decrease the rate of the tumor returning compared to traditional aggressive surgical removal of the tumor.

Eligibility Criteria

Sex: All

Age: 18+

Healthy Volunteers: Accepted

Inclusion Criteria:

  • Primary benign GCT of bone
  • Lesion located in an extremity
  • Lesion amenable to reconstruction (intralesional curettage) defined as having at least one intact column of bone after removal
  • No previous systemic bisphosphonate or denosumab therapy

Exclusion Criteria:

  • Recurrent GCT of bone
  • Non-extremity location
  • Lesion too extensive for intralesional treatment, either due to bone loss, joint invasion, or large soft tissue component

Interventions and Outcome Measures

Arms

no intervention: Control group

The surgical procedure for all patients will include extensive curettage of the lesion to remove macroscopic tumor, high-speed burring of the residual cavity, adjuvant treatment to the residual cavity, followed by packing of the cavity with either polymethylmethacrylate (PMMA) bone cement (Simplex P; Stryker, Mahwah, New Jersey) alone or bone cement with subchondral allograft bone graft. The choice of cavity reconstruction will be at the discretion of the treating surgeon. Traditional local adjuvants (argon beam coagulation, phenol, ethanol, or cryotherapy) will be used depending on surgeon preference. In addition to the above standard treatment, the patients will be randomized into one of two study arms. In Arm 1, the control group, no additional local therapy will be utilized.

experimental: Bisphosphonate group

In Arm 2, the bisphosphonate group, 4 mg of zoledronic acid (Zometa) will be added to each bag of bone cement.

Interventions

Zoledronic Acid

4 mg of zoledronic acid (Zometa) will be added to each bag of bone cement

Primary outcome measure

  • The endpoint for patient participation will be local recurrence [ Time Frame: Followed for 2 years postoperatively for study end points ]
