Nomogram for Giant Cell Tumor of Bone
骨巨細胞腫のノモグラム

Orthopedic surgeons perform curettage (joint-preserving surgery) rather than en bloc resection for bone giant cell tumors of the extremities in order to achieve good functional outcomes; however, a high local recurrence risk remains a concern. If the risk of local recurrence is adequately understood, careful examination and frequent imaging studies can be performed in high-risk patients, enabling early detection of local recurrence and subsequent curettage or radiofrequency ablation, thereby preserving the joint. We have developed a web-based nomogram to predict the risk of local recurrence after curettage of bone giant cell tumors of the extremities. This nomogram can be provided to clinicians to enhance their ability to assess patient prognosis, strengthen prognosis-based decision-making, improve patient stratification, and inform patients in the clinic. External validation using data from other institutions is required in the future.

This nomogram has been developed by Masunaga T, Tsukamoto S, Kurakami H, Honoki K, Fujii H, and Kido A from Nara Medical University, Nara, Japan and Donati DM and Errani C from IRCCS Istituto Ortopedico Rizzoli, Bologna, Italy.

The nomogram is intended solely to provide reference information based on statistics. When making actual treatment decisions, we recommend consulting with your attending physician. Our institutes shall not be liable for any disadvantages arising from the use of this nomogram. Use of this nomogram and the results of calculations are at your own risk. We encourage the user to rely on the published papers for details.
