What Factors Influence the Outcome of Surgically Treated Soft Tissue Sarcomas of the Hand and Wrist?

摘要

>Background: Soft tissue sarcomas (STS) of the hand are exceedingly rare. The aim of this study was to review our institution’s experience with STS of the hand to identify factors affecting outcomes and survivorship. >Methods: We retrospectively reviewed the records of 46 hand STS treated with definitive surgery at our institution between 1992 and 2013. Pertinent demographics as well as information regarding the surgical procedure, and disease status at latest follow-up were reviewed. Mean age at diagnosis was 38 years with a mean follow-up of 5 years. >Results: The most common tumor subtypes were epithelioid (n = 10) and synovial sarcoma (n = 8). Sixty-one percent were superficial in location. Thirty-three patients had had a nononcologic resection prior to definitive surgical treatment at our institution. Ultimately, negative margins were obtained in all cases. Local recurrence was observed in 5 patients and distant metastases in 14 patients. Tumor sizes ≥2 cm, American Joint Committee on Cancer (AJCC) grade, and depth of the tumor were found to adversely affect the outcome in terms of disease-free and overall survival. Reexcision of an inadvertently excised tumor at an outside institution did not adversely affect the outcome. The 10-year overall and disease-free survival was 72% and 63%. >Conclusions: Local recurrence after a wide excision was observed infrequently; however, distant disease was relatively common. Tumors with a size ≥2 cm were associated with a worse disease-free and overall survival, highlighting the aggressive nature of these tumors.
