Giant cell tumors of bone
- 1. Giant cell tumour of bone Dr Abdul G Suhail MBBS,D.Ortho,MS (Ortho) Assistant Professor in Orthopaedics
- 2. History First described in 1818 by Sir Astley Cooper Described in detail in 1940 by Jaffe and Litchenstein
- 3. GIANT CELL TUMOUR DEFINITION: Distinct neoplasm arising from non-bone forming supportive connective tissue of marrow with network of stromal cells regularly interspersed with giant cells. ( Jaffe & Liechtenstein )
- 4. AGE OF PRESENTATION 75-80% OF PATIENTS 20-50 YRS 10% 15-20 YRS 10% >60 yrs <1.7% BELOW 15 YRS
- 5. SEX Male:Female- 1:1.3 (Benign) -3:1 (Malignant)
- 6. SITE Epiphyseo-metaphyseal region of long bones GCT –Described from all bones EXCEPT middle ear bones Axial skeleton- 8% UL:LL-1:3
- 7. Site 55% AROUND THE KNEE 10% in the distal radius 6% in the proximal humerus SPINE rarely involved (commoner in the sacrum) In the head and neck region the maxilla and mandible are more commonly involved
- 8. GIANT CELL TUMOUR INTRA ARTICULAR EXTENSION- 10% TRANS OSSIOUS EXTENSION- 5% Common sites Wrist Ankle & foot Forearm Leg
- 9. MULTICENTRIC INVOLVEMENT Incidence-0.5-5% Simultaneous Peculiar features hand metaphyseal abundant spindle cells GOLTZ syndrome ` occular defects skeletal anomaly multifocal GCT
- 10. GIANT CELL TUMOUR SIGNS&SYMPTOMS 1. PAIN 2. SWELLING 3. JOINT RESTRICTION 4. MUSCLE WASTING 5. NEUROLOGICAL SIGNS 6. PATHOLOGICAL #
- 11. Pathology GROSS End of bone is expanded. Eccentric lesion at the epiphyseometaphyseal region. Thin periosteum. Fleshy dark brown, soft, friable mass. Cystic spaces seen.
- 12. PATHOLOGY GROSS-
- 13. Pathology Microscopy Vascularized network of round,oval or spindle shaped stromal cells and multinucleated giant cells with numerous centrally placed nuclei
- 15. Grading Jaffe,Lichenstein and Portis(1940) GRADE 1o Conventional GCT o Stroma is inconspicuous o Giant cells dominate the field o No atypism of stromal cells and are loosely arranged o Stromal cells are predominantly spindle shaped
- 16. Grading GRADE 2o Boderline tumours o Stromal cells are prominent and tightly packed o Giant cells are less in number compared to grade 1 and their nuclei may show atypism o Stromal cells show atypism o These tumours have a strong chance for recurrence and some may undergo malignant change
- 17. Grading GRADE 3o Sarcomatous type of stroma o Frequently metastase o Stromal cells abundant and closely compacted and present an irregular whorled arrangement o Nuclei are unusually large, irregular and atypical o Giant cells are few in number and atypical
- 18. Modified grading Sannerkin et al(1980) Malignant GCT- with frank sarcomatous changes and full metastatic potential Borderline GCT- without sarcomatous changes but with abnormal mitoses or vascular permeation or both Conventional GCT- without features of any of the above two types
- 19. No correlation exists between histological grading and clinical behavior of the tumour. Hence grading not widely accepted.
- 20. GIANT CELLS in Giant cell tumor Numerous nuclei(15-150) Centrally placed uniform size nuclei Tuberculosis Number of nuclei are less Peripherally placed nuclei
- 21. Enneking staging for GCT Stage 1-(10-15%) Patients asymptomatic Discovered incidentally May cause pathological fracture Has sclerotic rim on x-ray or CT Relatively inactive on bone scans Histologically benign
- 22. Enneking staging for GCT Stage 2-(70%) Symptomatic Often associated with path: fracture Has expanded cortex but no break through Is active on bone scans Histologically benign
- 23. Enneking staging for GCT Stage 3-(10-15%) Symptomatic Rapidly growing mass Has cortical perforation with accompanying soft tissue mass Activity on bone scan extends beyond the lesion in x ray Shows intense hypervascularity on angiogram Histologically benign
