Abstract
BACKGROUND: The management of the GCT continues to be controversial. The most accepted treatment reported is extended curettage with various adjuvants. However, the rate of recurrence has been very high (10-66%). For better understanding of the lesion and its management, it has become necessary to revise the existing grading system. MATERIALS AND METHODS: The recommendation of the proposed grading is based on 480 cases of GCT along with the analysis of other major reports published. Out of these, 279 were grade-II and 109 grade-III which were subjected to en bloc excision and reconstruction with non-vascularized fibular graft. Depending on the site, the grafts were stabilized with a suitable plate or extra long Kirschner wires. RESULTS: The observations made in 480 cases over a period of 5 decades revealed that for Campanacci grade-II and grade-III lesions, en bloc excision and suitable reconstruction resulted in minimum recurrence rate of 1.2%. The fibular reconstruction after excision has proved advantageous to our patients as it provides a stable joint in the form of an arthrodesis of the neighboring joint. CONCLUSION: GCT of bone has been a challenging lesion. Extended curettage has been recommended as the choice of treatment but the reported rate of recurrence has been high. En bloc excision and suitable reconstruction with fibular strut graft have resulted in 1.2% recurrence. It is, therefore, suggested the existing grading system should be revised mainly for grade-II and grade-III lesions which can bring down the high rate of recurrence in this unpredictable tumor. LEVEL OF EVIDENCE: Level-IV.
