Summary
Giant cell tumor (GCT) of bone is a rare bone tumor. This study analyzed 72 GCT cases, finding knee involvement in 54% and a 33% complication rate.
Area of Science:
- Orthopedic oncology
- Skeletal pathology
Background:
- Giant cell tumor (GCT) of bone is a primary bone tumor.
- GCTs are typically found in skeletally mature individuals.
Purpose of the Study:
- To describe the clinical characteristics and outcomes of 72 giant cell tumors of bone.
- To analyze the distribution, grading, and complications associated with GCT of bone.
Main Methods:
- Retrospective review of 72 diagnosed cases of GCT of bone.
- Analysis of patient demographics, tumor location, histological grading, and complications.
- Mean follow-up duration of 59.6 months for patients with at least two years of follow-up.
Main Results:
- The mean patient age was 35 years, with a female to male ratio of 1.3:1.
- Fifty-four percent of cases involved the knee region (distal femur, upper tibia, upper fibula).
- Histological grading revealed 49% grade I, 36% grade II, and 15% grade III GCTs. A 33% complication rate was observed.
Conclusions:
- Giant cell tumors of bone predominantly affect the knee region in adults.
- Histological grading is important for understanding GCT behavior and potential complications.
- Further research into GCT management and prevention of complications is warranted.
