Giant cell tumour (GCT) of bone is a benign but locally aggressive tumour. Although topical adjuvants have been used in the past, local recurrence following intralesional excision of GCT of bone continues to remain a problem. The use of bisphosphonates as an anti-osteoclastic agent in the management of osteolytic bone metastases is well accepted. Therefore our study aims to retrospectively demonstrate whether the administration of bisphosphonate as an adjuvant can control aggressive local recurrence of GCT and prevent wide resections of bones or amputations. A retrospective study was performed between 2004 and 2010. 6 patients were diagnosed with aggressive local recurrence of appendicular GCT. All patients were treated for the primary tumour by surgical curettage and cryoablation followed by cementation or biological reconstruction. In 5 patients the tumour was located in the distal radius and in one in the first metacarpal bone. All recurrences were in the bone with large soft-tissue extension. After histological diagnosis – by CT core needle biopsy – the patients were treated by intravenous bisphosphonate, followed by clinical & radiological assessments.Aim
Method
Cryosurgery is a well established modality in the treatment of benign aggressive and low grade malignant tumours. In this setting it allows for intra-lesional resection and preservation of function without compromising oncological outcome. Here we present the outcome of 87 patients treated with cryosurgery for low-grade chondrosarcoma of bone. 87 patients were treated between 1988 and 2005. The mean age was 51 years (range, 8-77 years), and included 47 females and 40 males. Minimal follow-up was two years. Patients were treated for lesions of the distal femur (n = 30), proximal humerus (n = 33), proximal femur (n = 5), proximal tibia (n = 10), and the remaining sites included the iliac bone, distal tibia, forearm, carpal and tarsal bones (n=10). Patients were treated with intralesional curettage through a cortical window, adjuvant burr drilling, cryotherpay and reconstruction with cement or bone graft and hardware fixation when that was clinically indicated.Background
