Giant cell tumor of bone

Area of Science:

• Orthopedic Oncology
• Skeletal Neoplasms
• Bone Tumor Treatment

Background:

• Giant cell tumor of bone (GCTB) is an uncommon bone neoplasm.
• High rates of local recurrence are frequently observed following treatment.
• Recurrence is often linked to tumor aggressiveness or incomplete surgical removal.

Purpose of the Study:

• To evaluate the efficacy of a specific conservative treatment protocol for giant cell tumors of bone.
• To assess the local recurrence rates associated with this management strategy.
• To compare the long-term functional outcomes with other treatment modalities.

Main Methods:

• Retrospective review of 27 GCTB cases treated between 1984 and 1994.
• Surgical interventions included resection/reconstruction for aggressive tumors (Grade 3) and curettage/cementation for one case.
• A combination of radical curettage, high-speed burring, pulsatile lavage, and bone grafting was used for 16 cases.

Main Results:

• None of the 16 cases treated with radical curettage and bone grafting experienced local recurrence after a minimum 5-year follow-up.
• Aggressive tumors (Campanacci Grade 3) were treated with resection and reconstruction.
• Conservative management provided a bony matrix for subchondral bone, potentially improving long-term joint function.

Conclusions:

• Appropriate staging and tailored treatment, including conservative management for select cases, can achieve excellent local control of giant cell tumors.
• The described conservative approach (radical curettage, burring, lavage, bone graft) is effective in preventing recurrence.
• This method may offer superior long-term joint function compared to cementation or other contemporary treatments.
