Surgery is the standard of care for symptomatic tenosynovial giant cell tumor (TGCT) when it can be accomplished without significant morbidity.1
Typically, arthroscopic synovectomy is used for resection of nodular-type TGCT (N-TGCT) while open synovectomy is common for diffuse-type TGCT (D-TGCT), however there is no clear consensus on the type of procedure.2 The preferred approach is resection when macroscopically complete resection is achievable, and it can be accomplished without significant morbidity for durable local control and improved QoL. The indication and expected outcome of surgery should be discussed with the multidisciplinary tumor board and patient.1
The likelihood of successful surgery is dependent on many factors, including location and subtype.1,3 N-TGCT can be managed by complete marginal resection, with low LRR. Surgery for D-TGCT is associated with high LR risk and postoperative complications. All cases should be discussed by the multidisciplinary tumor board.1
SURGERY FOR TGCT is not always curative1
Recurrence is still a risk following surgery for TGCT.
