From the Research
Giant cell tumors in the finger should be treated with surgical intervention, prioritizing curettage and bone grafting for smaller tumors, while considering denosumab as a neoadjuvant therapy to reduce tumor size and morbidity in selected cases, as supported by recent studies 1, 2.
Treatment Approach
The primary treatment for giant cell tumors in the finger involves surgical intervention. Curettage, which is the scraping out of the tumor, followed by bone grafting, is the most common approach for smaller, less aggressive tumors. This method aims to remove the tumor while preserving as much of the finger's function and structure as possible.
Role of Denosumab
Denosumab, a RANK ligand inhibitor, has been approved for the treatment of giant cell tumor of bone. Its role in the management of these tumors, especially in the context of finger involvement, is evolving. Denosumab can be considered as a neoadjuvant therapy to reduce tumor size, potentially making subsequent surgery less morbid 2. However, its use should be carefully considered, particularly in cases where curettage is planned, due to concerns about increased local recurrence rates 3.
Patient Evaluation and Follow-Up
Patients with giant cell tumors in the finger typically present with pain, swelling, and decreased range of motion in the affected finger. Diagnosis is confirmed through imaging studies such as X-rays and MRI, along with biopsy. After treatment, regular follow-up appointments are crucial due to the tumor's recurrence rate, which can range from 20-50%. Physical therapy may be recommended post-surgery to restore finger function and strength.
Considerations and Controversies
While denosumab offers a potential advancement in the management of giant cell tumors, particularly in cases where surgical options are limited, its long-term safety, optimal duration of treatment, and maintenance dose require further elucidation 1. The risk of local recurrence and malignant transformation with denosumab treatment is a concern that needs to be balanced against its benefits in reducing tumor size and potentially avoiding more extensive surgery.
Evidence Summary
Recent studies, including those published in 2020 and 2024 2, 1, provide insights into the efficacy and safety of denosumab in treating giant cell tumors of bone. These studies support the use of denosumab as part of the treatment strategy for selected cases, emphasizing the need for a multidisciplinary approach to manage these tumors effectively. The most recent and highest quality study 1 highlights denosumab's potential in reducing tumor size and improving patient outcomes, although it also notes the necessity of careful patient selection and monitoring due to potential complications.
