BACKGROUND
Giant cell tumor of bone (GCT) is a bone-destroying tumor that sometimes recurs locally after treatment. A recent study showed increased levels of serum total acid phosphatase (TACP).
METHODS
We assessed TACP in the serum of 26 patients with primary GCT, and in 5 of them who developed a local recurrence.
RESULTS
We found a correlation between TACP level in serum and tumor size. TACP levels that were elevated preoperatively in patients with GCT became normalized after surgery, but increased in 3 of the 5 patients with local recurrence.
CONCLUSIONS
TACP could be used as a tumor marker for monitoring response to treatment of GCT.
