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.

Condition or disease Intervention/treatment Phase
Giant Cell Tumor of Bone Drug: Zoledronic Acid Phase 3

Detailed Description:
The purpose of the clinical study is to investigate whether the local delivery of bisphosphonate (BP-loaded PMMA bone cement) as a surgical adjuvant can decrease the local recurrence rate of giant cell tumor of bone. The investigators will evaluate whether bisphonsphonate as a surgical adjuvant improves secondary outcomes, such as pain, function, fever, or wound complications. The hypothesis is that the local administration of bisphosphonate will decrease the recurrence rate of GCT compared to traditional aggressive intralesional curettage.

Arms and Interventions

Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Arm Intervention/treatment
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.
 Drug: Zoledronic Acid
4 mg of zoledronic acid (Zometa) will be added to each bag of bone cement
Other Name: zoledronate


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. The endpoint for patient participation will be local recurrence [ Time Frame: Followed for 2 years postoperatively for study end points ]
    Local recurrence of giant cell tumor of bone


Secondary Outcome Measures :
  1. MSTS Score [ Time Frame: Followed for 2 years postoperatively for study end points ]
    The Musculoskeletal Tumor Society (MSTS) scoring system is a validated and well-accepted functional scoring system used in orthopaedic oncology research

  2. Surgical site infection [ Time Frame: Follow-ups will consist of clinical visits. The clinical visits will be at 2 weeks postoperatively, 6 weeks postoperatively, and then every three months for the first two years after surgery. ]
    The surgical site will be assessed for a surgical site infection (SSI) as defined by CDC guidelines after surgery and during scheduled follow-up as outlined in time frame below.

  3. Wound healing [ Time Frame: Follow-ups will consist of clinical visits. The clinical visits will be at 2 weeks postoperatively, 6 weeks postoperatively, and then every three months for the first two years after surgery. ]
    The surgical site will be assessed after surgery and during scheduled follow-up as outlined in time frame below for wound healing issues/concerns.

  4. Potential bisphosphonate complications related to systemic administration [ Time Frame: Followed for 2 years postoperatively for study end points ]
    Patients will be followed for atypical femur fractures and avascular necrosis (AVN) of jaw
