The effect of surgical factors on recurrence of tendon sheath giant cell tumours

Abstract

In this retrospective study, we evaluated the impact of tumour-related and surgical factors on the recurrence of giant cell tumours of tendon sheath. A total of 95 patients were treated at our institution between February 2012 and March 2021. We identified the factors most likely to be associated with recurrence from evaluation of classification, neurovascular invasion, bone erosion and joint invasion. Based on these criteria, we identified 49 patients with a high risk of recurrence. Of the 95 patients, recurrence was observed in 17. Among the 49 patients classified as high-risk, 13 were found to have recurrence. This study demonstrates that recurrence is more common in the high-risk patient group. Level of evidence: IV
